This example demonstrates how you can wrap a C API
that has a callback interface, so that you can
pass Python functions to it as callbacks.
The files cheesefinder.h and cheesefinder.c
represent the C library to be wrapped.
The file cheese.pyx is the Pyrex module
which wraps it.
The file run_cheese.py demonstrates how to
call the wrapper.

This example demonstrates how Pyrex-generated code
can be called directly from a main program written in C.
In this example, the module's initialisation function
(called "initembedded", since the module is called
"embedded") is called explicitly. This is necessary
because the module is not being imported using the
normal Python import mechanism.
The Windows makefiles were contributed by
Duncan Booth <Duncan.Booth@SuttonCourtenay.org.uk>.

<hr width="100%"></center>
|
||||
|
||||
<h2>
|
||||
What is Pyrex all about?</h2>
|
||||
Pyrex is a language specially designed for writing Python extension modules.
|
||||
It's designed to bridge the gap between the nice, high-level, easy-to-use
|
||||
world of Python and the messy, low-level world of C.
|
||||
<p>You may be wondering why anyone would want a special language for this.
|
||||
Python is really easy to extend using C or C++, isn't it? Why not just
|
||||
write your extension modules in one of those languages?
|
||||
</p><p>Well, if you've ever written an extension module for Python, you'll
|
||||
know that things are not as easy as all that. First of all, there is a
|
||||
fair bit of boilerplate code to write before you can even get off the ground.
|
||||
Then you're faced with the problem of converting between Python and C data
|
||||
types. For the basic types such as numbers and strings this is not too
|
||||
bad, but anything more elaborate and you're into picking Python objects
|
||||
apart using the Python/C API calls, which requires you to be meticulous
|
||||
about maintaining reference counts, checking for errors at every step and
|
||||
cleaning up properly if anything goes wrong. Any mistakes and you have
|
||||
a nasty crash that's very difficult to debug.
|
||||
</p><p>Various tools have been developed to ease some of the burdens of producing
|
||||
extension code, of which perhaps <a href="http://www.swig.org">SWIG</a>
|
||||
is the best known. SWIG takes a definition file consisting of a mixture
|
||||
of C code and specialised declarations, and produces an extension module.
|
||||
It writes all the boilerplate for you, and in many cases you can use it
|
||||
without knowing about the Python/C API. But you need to use API calls if
|
||||
any substantial restructuring of the data is required between Python and
|
||||
C.
|
||||
</p><p>What's more, SWIG gives you no help at all if you want to create a new
|
||||
built-in Python <i>type. </i>It will generate pure-Python classes which
|
||||
wrap (in a slightly unsafe manner) pointers to C data structures, but creation
|
||||
of true extension types is outside its scope.
|
||||
</p><p>Another notable attempt at making it easier to extend Python is <a href="http://pyinline.sourceforge.net/">PyInline</a>
|
||||
, inspired by a similar facility for Perl. PyInline lets you embed pieces
|
||||
of C code in the midst of a Python file, and automatically extracts them
|
||||
and compiles them into an extension. But it only converts the basic types
|
||||
automatically, and as with SWIG, it doesn't address the creation
|
||||
of new Python types.
|
||||
</p><p>Pyrex aims to go far beyond what any of these previous tools provides.
|
||||
Pyrex deals with the basic types just as easily as SWIG, but it also lets
|
||||
you write code to convert between arbitrary Python data structures and
|
||||
arbitrary C data structures, in a simple and natural way, without knowing
|
||||
<i>anything</i> about the Python/C API. That's right -- <i>nothing at all</i>!
|
||||
Nor do you have to worry about reference counting or error checking --
|
||||
it's all taken care of automatically, behind the scenes, just as it is
|
||||
in interpreted Python code. And what's more, Pyrex lets you define new
|
||||
<i>built-in</i> Python types just as easily as you can define new classes
|
||||
in Python.
|
||||
</p><p>Sound too good to be true? Read on and find out how it's done.
|
||||
</p><h2>
|
||||
The Basics of Pyrex</h2>
|
||||
The fundamental nature of Pyrex can be summed up as follows: <b>Pyrex is
|
||||
Python with C data types</b>.
|
||||
<p><i>Pyrex is Python:</i> Almost any piece of Python code is also valid
|
||||
Pyrex code. (There are a few limitations, but this approximation will serve
|
||||
for now.) The Pyrex compiler will convert it into C code which makes equivalent
|
||||
calls to the Python/C API. In this respect, Pyrex is similar to the former
|
||||
Python2C project (to which I would supply a reference except that it no
|
||||
longer seems to exist).
|
||||
</p><p><i>...with C data types.</i> But Pyrex is much more than that, because
|
||||
parameters and variables can be declared to have C data types. Code which
|
||||
manipulates Python values and C values can be freely intermixed, with conversions
|
||||
occurring automatically wherever possible. Reference count maintenance
|
||||
and error checking of Python operations is also automatic, and the full
|
||||
power of Python's exception handling facilities, including the try-except
|
||||
and try-finally statements, is available to you -- even in the midst of
|
||||
manipulating C data.
|
||||
</p><p>Here's a small example showing some of what can be done. It's a routine
|
||||
for finding prime numbers. You tell it how many primes you want, and it
|
||||
returns them as a Python list.
|
||||
</p><blockquote><b><tt><font size="+1">primes.pyx</font></tt></b></blockquote>
|
||||
|
||||
<blockquote>
|
||||
<pre> 1 def primes(int kmax):<br> 2 cdef int n, k, i<br> 3 cdef int p[1000]<br> 4 result = []<br> 5 if kmax > 1000:<br> 6 kmax = 1000<br> 7 k = 0<br> 8 n = 2<br> 9 while k < kmax:<br>10 i = 0<br>11 while i < k and n % p[i] <> 0:<br>12 i = i + 1<br>13 if i == k:<br>14 p[k] = n<br>15 k = k + 1<br>16 result.append(n)<br>17 n = n + 1<br>18 return result</pre>
|
||||
</blockquote>
|
||||
You'll see that it starts out just like a normal Python function definition,
|
||||
except that the parameter <b>kmax</b> is declared to be of type <b>int</b>
|
||||
. This means that the object passed will be converted to a C integer (or
|
||||
a TypeError will be raised if it can't be).
|
||||
<p>Lines 2 and 3 use the <b>cdef</b> statement to define some local C variables.
|
||||
Line 4 creates a Python list which will be used to return the result. You'll
|
||||
notice that this is done exactly the same way it would be in Python. Because
|
||||
the variable <b>result</b> hasn't been given a type, it is assumed to hold
|
||||
a Python object.
|
||||
</p><p>Lines 7-9 set up for a loop which will test candidate numbers for primeness
|
||||
until the required number of primes has been found. Lines 11-12, which
|
||||
try dividing a candidate by all the primes found so far, are of particular
|
||||
interest. Because no Python objects are referred to, the loop is translated
|
||||
entirely into C code, and thus runs very fast.
|
||||
</p><p>When a prime is found, lines 14-15 add it to the p array for fast access
|
||||
by the testing loop, and line 16 adds it to the result list. Again, you'll
|
||||
notice that line 16 looks very much like a Python statement, and in fact
|
||||
it is, with the twist that the C parameter <b>n</b> is automatically converted
|
||||
to a Python object before being passed to the <b>append</b> method. Finally,
|
||||
at line 18, a normal Python <b>return</b> statement returns the result
|
||||
list.
|
||||
</p><p>Compiling primes.pyx with the Pyrex compiler produces an extension module
|
||||
which we can try out in the interactive interpreter as follows:
|
||||
</p><blockquote>
|
||||
<pre>>>> import primes<br>>>> primes.primes(10)<br>[2, 3, 5, 7, 11, 13, 17, 19, 23, 29]<br>>>></pre>
|
||||
</blockquote>
|
||||
See, it works! And if you're curious about how much work Pyrex has saved
|
||||
you, take a look at the <a href="primes.c">C code generated for this module</a>

Support for certain Python language features which are planned but not

</ul>
|
||||
|
||||
<ul>
|

<li>
|
||||
C++ support. This could be a very big can of worms - careful thought required
|

before going there.</li>
|
||||
</ul>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
Reading C/C++ header files directly would be very nice, but there are some
|
||||
severe problems that I will have to find solutions for first, such as what
|
||||
to do about preprocessor macros. My current thinking is to use a separate
|
||||
tool to convert .h files into Pyrex declarations, possibly with some manual
|

intervention.</li>

Use a <tt>cdef extern from</tt> block to include the Numeric header file

|

You're probably trying to access it through a reference which Pyrex thinks
|
||||
is a generic Python object. You need to tell Pyrex that it's a reference
|
||||
to your extension type by means of a declaration. For example,<br>
|
||||
<blockquote><tt>cdef class Vegetables:</tt><br>
|
||||
<tt> cdef int rhubarb</tt><br>
|
||||
<br>
|
||||
<tt>...</tt><br>
|

<tt>cdef Vegetables veg</tt><br>
|
||||
<tt>veg.rhubarb = 42</tt><br>

|

<h2><a name="Quack"></a>Python says my extension type has no method called 'quack', but I know it does. What gives?</h2>

You may have declared the method using <span style="font-family: monospace;">cdef</span> instead of <span style="font-family: monospace;">def</span>. Only functions and methods declared with <span style="font-family: monospace;">def</span> are callable from Python code.<br><br>

Python features</h2>
|
||||
Pyrex is not quite a full superset of Python. The following
|
||||
restrictions apply: <blockquote> <li> Function
|
||||
definitions (whether using <b>def</b> or <b>cdef</b>)
|
||||
cannot be nested within other function definitions.<br> </li>
|
||||
<li> Class definitions can only appear at the top
|
||||
level of a module, not inside a function.<br> </li>
|
||||
<li> The<tt> import *</tt> form of import
|
||||
is not allowed anywhere (other forms of the import statement are fine,
|
||||
though).<br> </li> <li> Generators
|
||||
cannot be defined in Pyrex.<br> <br> </li> <li>
|
||||
The <tt>globals()</tt> and <tt>locals()</tt>
|
||||
functions cannot be used.</li> </blockquote> The above
|
||||
restrictions will most likely remain, since removing them would be
|
||||
difficult and they're not really needed for Pyrex's intended
|
||||
applications. <p>There are also some temporary limitations,
|
||||
which may eventually be lifted, including: </p> <blockquote>
|
||||
<li> Class and function definitions cannot be placed inside
|
||||
control structures.<br> </li> <li> List comprehensions are not yet
|
||||
supported.<br> </li> <li> There is no
|
||||
support for Unicode.<br> </li> <li>
|
||||
Special methods of extension types cannot have functioning
|
||||
docstrings.<br> <br> </li> <li> The use of
|
||||
string literals as comments is not recommended at present, because they are not accepted in
|
||||
places where executable statements are not allowed.</li></blockquote><hr style="width: 100%; height: 2px;"><h2><a name="SemanticDifferences"></a>Semantic
|
||||
differences between Python and Pyrex</h2> <h3> Behaviour
|
||||
of class scopes</h3> In Python, referring to a method of a class
|
||||
inside the class definition, i.e. while the class is being defined,
|
||||
yields a plain function object, but in Pyrex it yields an unbound method<sup><font size="-2"><a href="#Footnote1">1</a></font></sup>.
|
||||
A consequence of this is that the
|
||||
usual idiom for using the classmethod and staticmethod functions, e.g. <blockquote>
|
||||
<pre>class Spam:</pre> <pre> def method(cls):<br> ...</pre><pre> method = classmethod(method)</pre>
|
||||
</blockquote>
|
||||
will not work in Pyrex. This can be worked around by defining the
|
||||
function <i>outside</i> the class, and then assigning the
|
||||
result of classmethod or staticmethod inside the class, i.e. <blockquote>
|
||||
<pre>def Spam_method(cls):<br> ...</pre> <pre>class Spam:</pre><pre> method = classmethod(Spam_method)</pre>
|
||||
</blockquote> <hr width="100%"><span style="font-weight: bold;">Footnotes</span><br><hr style="width: 100%; height: 2px;"><a name="Footnote1"></a>1.
|
||||
The reason for the different
|
||||
behaviour
|
||||
of class scopes is that Pyrex-defined Python functions are PyCFunction
|
||||
objects,
|
||||
not PyFunction objects, and are not recognised by the machinery that
|
||||
creates
|
||||
a bound or unbound method when a function is extracted from a class. To
|
||||
get
|
||||
around this, Pyrex wraps each method in an unbound method object itself
|
||||
before
|
||||
storing it in the class's dictionary.<br><br>--- </body></html>

|
||||
One of the main uses of Pyrex is wrapping existing libraries of C code.
|
||||
This is achieved by using <a href="#ExternDecls">external
|
||||
declarations</a> to declare the C functions and variables from
|
||||
the library that you want to use. <p>You can also use <a href="#PublicDecls">public declarations</a> to make C
|
||||
functions and variables defined in a Pyrex module available to external
|
||||
C code. The need for this is expected to be less frequent, but you
|
||||
might want to do it, for example, if you are embedding Python in
|
||||
another application as a scripting language. Just as a Pyrex module can
|
||||
be used as a bridge to
|
||||
allow Python code to call C code, it can also be used to allow C code
|
||||
to
|
||||
call Python code.</p><hr style="width: 100%; height: 2px;"> <h2> <a name="ExternDecls"></a>External
|
||||
declarations</h2> By default, C functions and variables declared
|
||||
at the module level are local to the module (i.e. they have the C <b>static</b>
|
||||
storage class). They can also be declared <b>extern</b> to
|
||||
specify that they are defined elsewhere, for example: <blockquote>
|
||||
<pre>cdef extern int spam_counter</pre> <pre>cdef extern void order_spam(int tons)</pre></blockquote>
|
||||
<h3>
|
||||
<a name="ReferencingHeaders"></a>Referencing C
|
||||
header files</h3> When you use an extern definition on its own as
|
||||
in the examples above, Pyrex includes a declaration for it in the
|
||||
generated C file. This can cause problems if the declaration doesn't
|
||||
exactly match the declaration that will be seen by other C code. If
|
||||
you're wrapping an existing C library, for example, it's important that
|
||||
the generated C code is compiled with exactly the same declarations as
|
||||
the rest of the library. <p>To achieve this, you can tell Pyrex
|
||||
that the declarations are to be found in a C header file, like this: </p>
|
||||
<blockquote> <pre>cdef extern from "spam.h":</pre> <pre> int spam_counter</pre><pre> void order_spam(int tons)</pre>
|
||||
</blockquote> The <b>cdef extern from</b> clause
|
||||
does three things: <ol><li> It directs Pyrex to place a <b>#include</b>
|
||||
statement for the named header file in the generated C code.<br> </li>
|
||||
<li> It prevents Pyrex from generating any C code for
|
||||
the declarations found in the associated block.<br> </li>
|
||||
<li> It treats all declarations within the block as
|
||||
though they
|
||||
started with <b>cdef extern</b>.</li></ol>
|
||||
It's important to understand that Pyrex does <i>not</i>
|
||||
itself read the C header file, so you still need to provide Pyrex
|
||||
versions of any declarations from it that you use. However, the Pyrex
|
||||
declarations don't always have to
|
||||
exactly match the C ones, and in some cases they shouldn't or can't. In
|
||||
particular: <ol><li> Don't use <b>const</b>.
|
||||
Pyrex doesn't know anything about const,
|
||||
so just leave it out. Most of the time this shouldn't cause any
|
||||
problem,
|
||||
although on rare occasions you might have to use a cast.<sup><a href="#Footnote1"> 1</a></sup><br> </li>
|
||||
<li> Leave out any platform-specific extensions to C
|
||||
declarations such as <b>__declspec()</b>.<br> </li>
|
||||
<li> If the header file declares a big struct and you
|
||||
only want
|
||||
to use a few members, you only need to declare the members you're
|
||||
interested in. Leaving the rest out doesn't do any harm, because the C
|
||||
compiler will use the full definition from the header file.<br> <br>
|
||||
In some cases, you might not need <i>any</i> of the
|
||||
struct's members, in
|
||||
which case you can just put <tt>pass</tt> in the body of
|
||||
the struct declaration,
|
||||
e.g.<br> <br> <tt> cdef extern
|
||||
from "foo.h":<br>
|
||||
struct spam:<br>
|
||||
pass</tt><br> <br>
|
||||
Note that you can only do this inside a <b>cdef extern from</b>
|
||||
block; struct
|
||||
declarations anywhere else must be non-empty.<br> <br> </li><li>
|
||||
If the header file uses typedef names such as <b>size_t </b>to
|
||||
refer to platform-dependent flavours of numeric types, you will need a
|
||||
corresponding <b>ctypedef</b> statement, but you don't
|
||||
need to match the type exactly, just use something of the right general
|
||||
kind (int, float, etc). For example,</li><ol><pre>ctypedef int size_t</pre></ol>
|
||||
will work okay whatever the actual size of a size_t is (provided the
|
||||
header file defines it correctly). <br> <li>
|
||||
If the header file uses macros to define constants, translate them into
|
||||
a dummy <b>enum</b> declaration.<br> </li>
|
||||
<li> If the header file defines a function using a
|
||||
macro, declare it as though it were an ordinary function, with
|
||||
appropriate argument and
|
||||
result types.</li></ol> A few more tricks and tips: <ul><li>
|
||||
If you want to include a C header because it's needed by another
|
||||
header, but don't want to use any declarations from it, put <tt><font size="+1">pass</font></tt> in the extern-from
|
||||
block:</li></ul> <ul><ul><tt>cdef extern
|
||||
from "spam.h":</tt><br><tt>
|
||||
pass</tt></ul></ul> <ul><li> If you want
|
||||
to include some external declarations, but don't want to specify a
|
||||
header file (because it's included by some other header that you've

|
||||
header file name:</li></ul> <blockquote> <blockquote><tt>cdef

||||
extern from *:</tt> <br> <tt>
|
||||
...</tt></blockquote> </blockquote> <h3> <a name="StructDeclStyles"></a>Styles of struct, union
|
||||
and enum declaration</h3> There are two main ways that structs,
|
||||
unions and enums can be declared in C header files: using a tag name,
|
||||
or using a typedef. There are also some variations based on various
|
||||
combinations of these. <p>It's important to make the Pyrex
|
||||
declarations match the style used in the
|
||||
header file, so that Pyrex can emit the right sort of references to the
|
||||
type
|
||||
in the code it generates. To make this possible, Pyrex provides two
|
||||
different
|
||||
syntaxes for declaring a struct, union or enum type. The style
|
||||
introduced
|
||||
above corresponds to the use of a tag name. To get the other style, you
|
||||
prefix
|
||||
the declaration with <b>ctypedef</b>, as illustrated
|
||||
below. </p> <p>The following table shows the various
|
||||
possible styles that can be found in a header file, and the
|
||||
corresponding Pyrex declaration that you should put in the <b>cdef
|
||||
exern from </b>block. Struct declarations are used as an
|
||||
example; the same applies equally to union and enum declarations. </p>
|
||||
<p>Note that in all the cases below, you refer to the type in
|
||||
Pyrex code simply
|
||||
as <tt><font size="+1">Foo</font></tt>,
|
||||
not <tt><font size="+1">struct Foo</font></tt>.

<a name="AccessingAPI"></a>Accessing
|
||||
Python/C API routines</h3> One particular use of the <b>cdef
|
||||
extern from</b> statement is for gaining access to routines in
|
||||
the Python/C API. For example, <blockquote> <pre>cdef extern from "Python.h":</pre>
|
||||
<pre> object PyString_FromStringAndSize(char *s, Py_ssize_t len)</pre></blockquote>
|
||||
will allow you to create Python strings containing
|
||||
null bytes. <h3> <a name="SpecialTypes"></a>Special
|
||||
Types</h3><p>Pyrex predefines the name <span style="font-family: monospace;">Py_ssize_t</span>
|
||||
for use with Python/C API routines. To make your extensions compatible
|
||||
with 64-bit systems, you should always use this type where it is
|
||||
specified in the documentation of Python/C API routines.</p><h3><a name="CallingConventions"></a>Windows Calling
|
||||
Conventions</h3><p>The <span style="font-family: monospace;">__stdcall</span>, <span style="font-family: monospace;">__fastcall</span> and <span style="font-family: monospace;">__cdecl</span> calling
|
||||
convention specifiers can be used in Pyrex, with the same syntax as
|
||||
used by C compilers on Windows, for example,</p><pre style="margin-left: 40px;">cdef extern int __stdcall FrobnicateWindow(long handle)<br><br>cdef void (__stdcall *callback)(void *)<br></pre>If
|
||||
__stdcall is used, the function is only considered compatible with
|
||||
other __stdcall functions of the same signature.<br><br> <hr width="100%"> <h2> <a name="CNameSpecs"></a>Resolving
|
||||
naming conflicts - C name specifications</h2> Each Pyrex module
|
||||
has a single module-level namespace for both Python
|
||||
and C names. This can be inconvenient if you want to wrap some external
|
||||
C functions and provide the Python user with Python functions of the
|
||||
same
|
||||
names. <p>Pyrex 0.8 provides a couple of different ways of
|
||||
solving this problem. The best way, especially if you have many C
|
||||
functions to wrap, is probably to put the extern C function
|
||||
declarations into a different namespace using the facilities described
|
||||
in the section on <a href="sharing.html">sharing
|
||||
declarations between Pyrex modules</a>. </p> <p>The
|
||||
other way is to use a <b>c name specification</b> to give
|
||||
different Pyrex and C names to the C function. Suppose, for example,
|
||||
that you want to wrap an external function called <tt>eject_tomato</tt>.
|
||||
If you declare it as </p> <blockquote> <pre>cdef extern void c_eject_tomato "eject_tomato" (float speed)</pre>
|
||||
</blockquote> then its name inside the Pyrex module will be <tt>c_eject_tomato</tt>,
|
||||
whereas its name in C will be <tt>eject_tomato</tt>. You
|
||||
can then wrap it with <blockquote> <pre>def eject_tomato(speed):<br> c_eject_tomato(speed)</pre>
|
||||
</blockquote> so that users of your module can refer to it as <tt>eject_tomato</tt>.
|
||||
<p>Another use for this feature is referring to external names
|
||||
that happen to be Pyrex keywords. For example, if you want to call an
|
||||
external function called <tt>print</tt>, you can rename it
|
||||
to something else in your Pyrex module. </p> <p>As well
|
||||
as functions, C names can be specified for variables, structs, unions,
|
||||
enums, struct and union members, and enum values. For example, </p>
|
||||
<blockquote> <pre>cdef extern int one "ein", two "zwei"<br>cdef extern float three "drei"<br><br>cdef struct spam "SPAM":<br> int i "eye"</pre><tt>cdef
|
||||
enum surprise "inquisition":</tt> <br> <tt>
|
||||
first "alpha"</tt> <br> <tt> second
|
||||
"beta" = 3</tt></blockquote> <hr width="100%">

<h2><a name="Using_Pyrex_Declarations_from_C"></a>Using
|
||||
Pyrex Declarations from C</h2>Pyrex
|
||||
provides two methods for making C declarations from a Pyrex module
|
||||
available for use by external C code – public declarations and C API
|
||||
declarations.<br><br><div style="margin-left: 40px;"><span style="font-weight: bold;">NOTE:</span> You do <span style="font-style: italic;">not</span> need to use
|
||||
either of these to make declarations from one Pyrex module available to
|
||||
another Pyrex module – you should use the <span style="font-weight: bold;">cimport</span> statement
|
||||
for that. <a href="sharing.html">Sharing Declarations
|
||||
Between Pyrex Modules</a>.</div><h3><a name="PublicDecls"></a>Public Declarations</h3>
|
||||
You can make C types, variables and functions defined in a Pyrex module
|
||||
accessible to C code that is linked with the module, by declaring them
|
||||
with the <b><tt>public</tt></b> keyword: <blockquote><tt>cdef
|
||||
public struct Bunny: # public type declaration<br>
|
||||
int vorpalness<br><br>cdef public int spam #
|
||||
public variable declaration</tt> <p><tt>cdef public
|
||||
void grail(Bunny *): # public function declaration</tt> <br>
|
||||
<tt> ...</tt></p> </blockquote>
|
||||
If there are any <tt>public</tt> declarations in a Pyrex
|
||||
module, a header file called <b><span style="font-style: italic;">modulename</span>.h</b>
|
||||
file is generated containing equivalent C declarations for inclusion in
|
||||
other C code.<br><br>Any
|
||||
C code wanting to make use of these declarations will need to be
|
||||
linked, either statically or dynamically, with the extension module.<br><br>If
|
||||
the Pyrex module resides within a package, then the name of the .h file
|
||||
consists of the full dotted name of the module, e.g. a module called <span style="font-weight: bold;">foo.spam</span> would have
|
||||
a header file called <span style="font-weight: bold;">foo.spam.h</span>.
|
||||
<h3><a name="C_API_Declarations"></a>C API
|
||||
Declarations</h3><p>The other way of making declarations available to C code is to declare them with the <span style="font-family: monospace; font-weight: bold;">api</span>
|
||||
keyword. You can use this keyword with C functions and extension types. A header file called "<span style="font-weight: bold;"><span style="font-style: italic;">modulename</span>_api.h</span>"
|
||||
is produced containing declarations of the functions and extension types, and a function
|
||||
called <span style="font-weight: bold;">import_<span style="font-style: italic;">modulename</span>()</span>.</p><p>C
|
||||
code wanting to use these functions or extension types needs to include the header and call

the import_<span style="font-style: italic;">modulename</span>()

with the extension module in any way, as the Python import machinery is

both, otherwise you may get conflicting dual definitions.<br><br>If

|

provides facilities for releasing the Global Interpreter Lock (GIL)
|

before calling C code, and for acquiring the GIL in functions that are

to be called back from C code that is executed without the GIL.<br><h3>Releasing the GIL</h3>You can release the GIL around a section of code using the<span style="font-family: monospace; font-weight: bold;"> with nogil </span>statement:<br><pre style="margin-left: 40px;">with nogil:<br> <code to be executed with the GIL released><br></pre>Code in the body of the statement <span style="font-style: italic;">must not manipulate Python objects</span>,

This section describes a new set of facilities introduced in Pyrex 0.8
|
||||
for making C declarations, functions and extension types in one Pyrex module available
|
||||
for use in another Pyrex module. These facilities are closely modelled on
|
||||
the Python import mechanism, and can be thought of as a compile-time version
|
||||
of it.

<h2><a class="mozTocH2" name="mozTocId989010"></a> <a name="DefAndImpFiles"></a>Definition and Implementation files</h2>
|
||||
|
||||
A Pyrex module can be split into two parts: a <i>definition file</i> with
|
||||
a <tt>.pxd</tt> suffix, containing C declarations that are to be available
|
||||
to other Pyrex modules, and an <i>implementation file</i> with a <tt>.pyx</tt>
|
||||
suffix, containing everything else. When a module wants to use something
|
||||
declared in another module's definition file, it imports it using the <a href="#CImportStatement"><b>cimport</b> statement</a>.
|
||||
<h3><a class="mozTocH3" name="mozTocId411233"></a> <a name="WhatDefFileContains"></a>What a Definition File contains</h3>
|
||||
|
||||
A definition file can contain:
|
||||
<ul>
|
||||
|
||||
<li> Any kind of C type declaration.</li>
|
||||
|
||||
<li> <b>extern</b> C function or variable declarations.</li><li>Declarations of C functions defined in the module.</li>
|
||||
|
||||
<li> The definition part of an extension type (<a href="#SharingExtensionTypes">see below</a>).</li>
|
||||
|
||||
|
||||
</ul>
|
||||
|
||||
It cannot contain any non-extern C variable declarations.
|
||||
<p>It cannot contain the implementations of any C or Python functions, or
|
||||
any Python class definitions, or any executable statements. </p>
|
||||
|
||||
|
||||
<blockquote>NOTE: You don't need to (and shouldn't) declare anything in a
|
||||
declaration file <b>public</b> in order to make it available to other Pyrex
|
||||
modules; its mere presence in a definition file does that. You only need a
|
||||
public declaration if you want to make something available to external C code.</blockquote>

<h3><a class="mozTocH3" name="mozTocId20347"></a> <a name="WhatImpFileContains"></a>What an Implementation File contains</h3>
|
||||
|
||||
An implementation file can contain any kind of Pyrex statement, although
|
||||
there are some restrictions on the implementation part of an extension type
|
||||
if the corresponding definition file also defines that type (see below).
|
||||
|
||||
<h2><a class="mozTocH2" name="mozTocId950993"></a> <a name="CImportStatement"></a>The <tt>cimport</tt> statement</h2>
|
||||
|
||||
The <b>cimport</b> statement is used in a definition or implementation
|
||||
file to gain access to names declared in another definition file. Its syntax
|
||||

<p>It is important to understand that the <b>cimport</b> statement can <i>only</i>
|
||||
be used to import C data types, C functions and variables, and extension
|
||||
types. It cannot be used to import any Python objects, and (with one exception)
|
||||
it doesn't imply any Python import at run time. If you want to refer to any
|
||||
Python names from a module that you have cimported, you will have to include
|
||||
a regular <b>import</b> statement for it as well. </p>
|
||||
|
||||
|
||||
<p>The exception is that when you use <b>cimport</b> to import an extension
|
||||
type, its type object is imported at run time and made available by the
|
||||
name under which you imported it. Using <b>cimport</b> to import extension
|
||||
types is covered in more detail <a href="#SharingExtensionTypes">below</a>.

|

|

When you <b>cimport</b> a module called <tt>modulename</tt>, the Pyrex

compiler searches for a file called <tt>modulename.pxd</tt> along the search

||||
path for include files, as specified by <b>-I</b> command line options.
|
||||
<p>Also, whenever you compile a file <tt>modulename.pyx</tt>, the corresponding
|
||||
definition file <tt>modulename.pxd</tt> is first searched for along the

conflicts</h3>
|
||||
|
||||
The cimport mechanism provides a clean and simple way to solve the problem
|
||||
of wrapping external C functions with Python functions of the same name.
|
||||
All you need to do is put the extern C declarations into a .pxd file for
|
||||
an imaginary module, and cimport that module. You can then refer to the C
|
||||
functions by qualifying them with the name of the module. Here's an example:

|
||||
|
||||
An extension type can be made available via cimport by splitting its definition into two parts, one in
|
||||
a definition file and the other in the corresponding implementation file.
|
||||
<br>
|
||||
|
||||
<br>
|
||||
|
||||
The definition part of the extension type can only declare C attributes
|
||||
and C methods, not Python methods, and it must declare <i>all</i> of that
|
||||
type's C attributes and C methods.<br>
|
||||
|
||||
<br>
|
||||
|
||||
The implementation part must implement all of the C methods declared in
|
||||
the definition part, and may not add any further C attributes or methods. It may also
|
||||
define Python methods.
|
||||
<p>Here is an example of a module which defines and exports an extension
|
||||
type, and another module which uses it. <br>

<p>Some things to note about this example: </p>
|

|
||||
|
||||
<ul>
|
||||
|
||||
<li> There is a <tt>cdef</tt> <tt>class</tt> <tt>Shrubbery</tt> declaration in both Shrubbing.pxd
|
||||
and Shrubbing.pyx. When the Shrubbing module is compiled, these two declarations
|
||||
are combined into one.</li>
|
||||
|
||||
|
||||
<li> In Landscaping.pyx, the <tt>cimport</tt> <tt>Shrubbing</tt> declaration
|
||||
allows us to refer to the Shrubbery type as <tt>Shrubbing.Shrubbery</tt>.
|
||||
But it doesn't bind the name <tt>Shrubbing</tt> in Landscaping's module namespace
|
||||
at run time, so to access <tt>Shrubbing.standard_shrubbery</tt> we also
|
||||
need to <tt>import</tt> <tt>Shrubbing</tt>.</li>
|
||||
|
||||
|
||||
</ul>If you are exporting an extension type that has a base class, the
|
||||
base class must be declared in the definition part. Repeating the base
|
||||
class in the implementation part is not necessary, but if you do, it
|
||||
must match the base class in the definition part.<h2><a class="mozTocH2" name="mozTocId144977"></a><a name="CircularCImports"></a>Circular cimports</h2>If
|
||||
you have two structs, unions or extension types defined in different
|
||||
.pxd files, and they need to refer to each other, there is a potential
|
||||
for problems with circular imports. These problems can be avoided by
|
||||
placing forward declarations of all the structs, unions and extension
|
||||
types defined in the .pxd file <span style="font-style: italic;">before</span> the first <span style="font-family: monospace;">cimport</span> statement.<br><br>For example:<br><br><table style="text-align: left; margin-left: 40px;" border="1" cellpadding="5" cellspacing="2"><tbody><tr><td style="vertical-align: top; white-space: nowrap; text-align: left; background-color: rgb(255, 204, 24); font-family: monospace;">foo.pxd</td><td style="vertical-align: top; white-space: nowrap; text-align: left; background-color: rgb(255, 204, 24); font-family: monospace;">blarg.pxd</td></tr><tr><td style="vertical-align: top; white-space: nowrap; text-align: left; font-family: monospace; background-color: rgb(255, 204, 24);">cdef struct Spam<br><br>from blarg cimport Eggs<br><br>cdef struct Spam:<br> Eggs *eggs</td><td style="vertical-align: top; white-space: nowrap; text-align: left; background-color: rgb(255, 204, 24); font-family: monospace;">cdef struct Eggs<br><br>from foo cimport Spam<br><br>cdef struct Eggs:<br> Spam *spam</td></tr></tbody></table><br>If
|
||||
the forward declarations weren't present, a circular import problem
|
||||
would occur, analogous to that which arises in Python when two modules
|
||||
try to import names from each
|
||||
other. Placing the forward declarations before the <span style="font-family: monospace;">cimport</span> statements ensures that all type names are known to the Pyrex compiler sufficiently far in advance.<br><br>Note
|
||||
that any .pyx file is free to cimport anything it wants from any .pxd
|
||||
file without needing this precaution. It's only when two .pxd files
|
||||
import each other that circular
|
||||
import issues arise. <hr width="100%">Back to the <a href="overview.html">Language Overview</a>

|

source file names consist of the name of the module followed by a <span style="font-family: monospace;">.pyx</span> extension,
|
||||
for example a module called <span style="font-family: monospace;">primes</span>
|
||||
would have a source file named <span style="font-family: monospace;">primes.pyx</span>.<br><h2><a class="mozTocH2" name="mozTocId146379"></a>Modules in Packages</h2>If
|
||||
your module is destined to live in a package, the Pyrex compiler needs
|
||||
to know the fully-qualified name that the module will eventually have.<br><br>There are currently two ways to give it this information:<br><ol><li>Name the source file with the full dotted name of the module. For
|
||||
example, a module called <span style="font-family: monospace;">primes</span> to be installed in a package called <span style="font-family: monospace;">numbers</span> would
|
||||
have a source file called <span style="font-family: monospace;">numbers.primes.pyx</span>.<br><br></li><li>Place the source file in a <span style="font-style: italic;">package directory</span>. To Pyrex, a package directory is one that contains a file called either <span style="font-family: monospace;">__init__.py</span> or <span style="font-family: monospace;">__init__.pyx</span>. For example, a package called <span style="font-family: monospace;">numbers</span> containing a module called <span style="font-family: monospace;">primes</span> would have the source files laid out like this:</li></ol><div style="margin-left: 80px;"><span style="font-family: monospace;">numbers</span><br style="font-family: monospace;"><div style="margin-left: 40px;"><span style="font-family: monospace;">__init__.py</span><br style="font-family: monospace;"><span style="font-family: monospace;">primes.pyx</span><br></div></div><br>This will ensure that the __name__ properties of the module and any
|
||||
classes defined in it are set correctly. If you don't do this, you may
|
||||
find that pickling doesn't work, among other problems. It also ensures
|
||||
that the Pyrex compiler has the right idea about the layout of the
|
||||
module namespace, which can be important when accessing extension types
|
||||
defined in other modules.<br>
|
||||
<h2><a class="mozTocH2" name="mozTocId431365"></a>Building an Extension</h2>There are two steps involved in creating an extension module from Pyres sources:<br><ol><li>Use the Pyrex compiler to translate the .pyx file into a .c file.</li><li>Compile the .c file with a C compiler and link it with whatever libraries it needs, to produce an extension module.</li></ol>There
|
||||
are a variety of ways of accomplishing these steps, either separately
|
||||
or together. One way is to compile the Pyrex source manually from the
|
||||
command line
|
||||
with the Pyrex compiler, e.g.<br>
|
||||
<br><div style="margin-left: 40px;"><span style="font-family: monospace;">pyrexc -r primes.pyx</span><br>
|
||||
</div><br>
|
||||
This will compile <span style="font-family: monospace;">primes.pyx</span>
|
||||
and any other source files that it depends on, if any of them have
|
||||
changed since the last compilation, and produce a file called <span style="font-family: monospace;">primes.c</span>,
|
||||
which then needs to be compiled with the C compiler using whatever
|
||||
options are appropriate on your platform for generating an extension
|
||||
module.<br><br>You
|
||||
can perform the C compilation using distutils and a <span style="font-family: monospace;">setup.py</span> file, or with a conventional
|
||||
Makefile. There's a Makefile in the Demos directory (called <span style="font-family: monospace;">Makefile.nodistutils</span>)
|
||||
that shows how to do this for Linux.<br><br>Another approach is to put code at the beginning of your <span style="font-family: monospace;">setup.py</span> file to import the Pyrex compiler and call it from Python. You can then follow this with a normal call to <span style="font-family: monospace;">setup()</span> to compile the resulting .c files.<br>
|
||||
<br>You can also perform both steps at once in a <span style="font-family: monospace;">setup.py</span> file using the distutils
|
||||
extension provided with Pyrex. See the <span style="font-family: monospace;">Setup.py</span>
|
||||
file in the <span style="font-family: monospace;">Demos</span>
|
||||
directory for an example of how to use it. A disadvantage of this
|
||||
method is that you won't be able to take advantage of Pyrex's own
|
||||
dependency checking features to compile only the Pyrex sources which
|
||||
have changed.<br><h3><a class="mozTocH3" name="mozTocId233830"></a>Command Line</h3>You can run the Pyrex compiler from the command line using either the <span style="font-family: monospace;">pyrexc</span> shell command or the Python version of it, <span style="font-family: monospace;">pyrexc.py</span>.<br><br>The following command line options exist:<br><br><table style="text-align: left; margin-left: 40px;" border="1" cellpadding="2" cellspacing="2"><tbody><tr><td style="font-weight: bold;" align="left" nowrap="nowrap" valign="top">Short</td><td style="font-weight: bold;" align="left" nowrap="nowrap" valign="top">Long</td><td style="font-weight: bold;" align="left" nowrap="nowrap" valign="top">Description</td></tr><tr><td align="left" nowrap="nowrap" valign="top">-v</td><td align="left" nowrap="nowrap" valign="top">--version</td><td align="left" nowrap="nowrap" valign="top">Display the version number of the Pyrex compiler</td></tr><tr><td align="left" nowrap="nowrap" valign="top">-l</td><td align="left" nowrap="nowrap" valign="top">--create-listing</td><td align="left" nowrap="nowrap" valign="top">Produces a .lis file for each compiled .pyx file containing error messages</td></tr><tr><td align="left" nowrap="nowrap" valign="top">-I</td><td align="left" nowrap="nowrap" valign="top">--include-dir</td><td style="vertical-align: top; text-align: left; width: 200px;">Specifies

|
||||
distutils extension provided with Pyrex allows you to pass .pyx files
|

directly to the Extension constructor in your setup file.<br><br>To use it, you need to put the following at the top of your setup.py file:<br><br><div style="margin-left: 40px; font-family: monospace;">from Pyrex.Distutils.extension import Extension<br>from Pyrex.Distutils import build_ext<br></div><br>and you need to specify the Pyrex version of the build_ext command class in your setup() call:<br><br><div style="margin-left: 40px; font-family: monospace;">setup(<br> ...<br> cmdclass = {'build_ext': build_ext}<br>)<br></div><br>Using
|
||||
the distutils extension is not currently recommended, because it's
|
||||
unable to automatically find cimported modules or check the timestamps
|
||||
of .pxd files and included sources. It also makes it harder to turn off
|
||||
the use of Pyrex for people who are only installing your module and not
|
||||
modifying the sources.<br><h2><a class="mozTocH2" name="mozTocId559484"></a>Distributing Pyrex modules</h2>It
|
||||
is strongly recommended that you distribute the generated .c files as
|
||||
well as your Pyrex sources, so that users can install your module
|
||||
without needing to have Pyrex available.<br><br>It is also recommended that Pyrex compilation <span style="font-style: italic;">not</span>
|
||||
be enabled by default in the version you distribute. Even if the user
|
||||
has Pyrex installed, he probably doesn't want to use it just to install
|
||||
your module. Also, the version he has may not be the same one you used,
|
||||
and may not compile your sources correctly.<br><br>---<br></body></html>

<html><head><meta content="text/html; charset=ISO-8859-1" http-equiv="content-type"><title>0.9.9 Release Notes</title></head><body><h1>Release Notes for Pyrex 0.9.9</h1><h2>C++ Features</h2>Some features for interfacing with C++ code have been introduced in this release. Structs declared with '<span style="font-family: monospace;">cdef+ struct</span>' may have constructors and member functions, there is a '<span style="font-family: monospace;">new</span>' operator for instantiating them, and they may be deallocated using the '<span style="font-family: monospace;">del</span>' operator. Details may be found in the <a href="LanguageOverview.html">Language Overview</a> under <a href="Manual/using_with_c++.html">Using Pyrex with C++</a>.<br><h2>Changes to Exception Semantics</h2>The
|
||||
behaviour surrounding exceptions caught using a try-except statement
|
||||
were previously an inconsistent mixture of Pyrex and Python semantics.
|
||||
Attempts to make the behaviour match Python more closely were requiring
|
||||
the generation of increasingly convoluted and inefficient code, so I
|
||||
decided to backtrack and return to something simpler.<br><br>Pyrex no
|
||||
longer places caught exceptions into the thread state. This ensures
|
||||
that exceptions and tracebacks do not leak out of the except clause
|
||||
that caught them, unless you do something to explicitly preserve them.<br><br>It also means that you <span style="font-style: italic;">cannot</span> retrieve an caught exception in Pyrex using <span style="font-family: monospace;">sys.exc_info()</span>. If you want to capture the exception, you need to bind it to a name in the <span style="font-family: monospace;">except</span> clause.<br><br>To capture the traceback, the syntax of the <span style="font-family: monospace;">except</span> clause has been extended to allow a third argument. For example,<br><pre style="margin-left: 40px;">try:<br> start_vehicle()<br>except HovercraftError, err, tb:<br> print "Can't start:", err<br> traceback.print_tb(tb)<br></pre>As previously, a <span style="font-family: monospace;">raise</span> statement with no arguments must be lexically enclosed in the <span style="font-family: monospace;">except</span>
|
||||
clause which caught the exception that you are trying to re-raise. In
|
||||
order to re-raise it from somewhere else, you will need to explicity
|
||||
communicate the exception and traceback to that place and use an
|
||||
ordinary <span style="font-family: monospace;">raise</span> statement.<br><h2>Planned Change to None-checking</h2>Currently,
|
||||
an argument to a Python function that is declared as an extension type
|
||||
will, by default, be allowed to receive the value None; to prevent
|
||||
this, you must qualify the argument declaration with '<span style="font-family: monospace;">not None</span>'.<br><br>This
|
||||
arrangement has proved to be error-prone, because it requires the
|
||||
programmer to be aware of the 'not None' feature and to remember to use
|
||||
it everywhere necessary. Failure to do so results in a Pyrex module
|
||||
that is prone to being crashed hard if it is passed a None value that
|
||||
it is not expecting.<br><br>To improve this situation, I am planning to make '<span style="font-family: monospace;">not None</span>' the default in a future release of Pyrex. In order to allow None as a legal argument value, it will be necessary to use an '<span style="font-family: monospace;">or None</span>' qualifier.<br><br>In release 0.9.9, the '<span style="font-family: monospace;">or None</span>'
|
||||
qualifier may be used, but it is optional. In preparation for the
|
||||
change of default, the Pyrex compiler will issue a warning (once per
|
||||
run) if it encounters an extension type argument that is not qualified
|
||||
with either 'or None' or 'not None'. For example, if <span style="font-family: monospace;">Spam</span> and <span style="font-family: monospace;">Eggs</span> are extension types and you have a function declared as<br><pre style="margin-left: 40px;">def frobulate(Spam s, Eggs e not None):<br> ...<br></pre>then in order to eliminate the warning, you will need to change it to<br><pre style="margin-left: 40px;">def frobulate(Spam s or None, Eggs e not None):<br> ...</pre>In a later release, when 'not None' has become the default, it will be possible to drop the 'not None' qualifiers.<br><h2>Non-GC Extension Types</h2>It
|
||||
is now possible to define and extension type with Python attributes
|
||||
that does not participate in cyclic garbage collection, using a new <span style="font-family: monospace;">nogc</span> option, for example:<br><pre style="margin-left: 40px;">cdef class Spam [nogc]:<br> """This class doesn't participate in GC even though<br> it has a Python attribute."""<br> object sausages</pre><h2>Other New Features</h2>Some other minor feature additions and modifications have been made.<br><ul><li><span style="font-family: monospace;">size_t </span>is now a built-in type and is the type returned by the <span style="font-family: monospace;">sizeof</span> operator. Also, the sizes of <span style="font-family: monospace;">size_t</span> and <span style="font-family: monospace;">Py_ssize_t</span> are now assumed to be somewhere between <span style="font-family: monospace;">long</span> and <span style="font-family: monospace;">long long</span>.<br><br></li><li>Operations
|
||||
between two int types of the same rank now return an
|
||||
unsigned result if either of the operands is unsigned; if the ranks
|
||||
differ, the result has the same type as the wider-ranked operand. I
|
||||
think this is the best
|
||||
approximation of the ANSI C rules that is possible without knowing the
|
||||
exact sizes of the types.<br><br><span style="font-family: monospace;"></span></li><li><span style="font-family: monospace;">PyString_InternFromString</span> is now exposed under the name <span style="font-family: monospace; font-weight: bold;">cintern</span><span style="font-weight: bold;"> </span>rather than <span style="font-family: monospace;">intern</span>, because it is not a complete replacement for the Python <span style="font-family: monospace;">intern</span> function (it can't handle strings containing null bytes).<br></li><li>The
|
||||
size check that was previously generated when importing an extension
|
||||
type has been disabled for the time being until I can think of
|
||||
something better. It was generating too many false positives, for
|
||||
example from different versions of numpy.<br><br></li><li>The <span style="font-family: monospace;">__fastcall</span> calling convention option is now supported. Also, Pyrex no longer assumes that <span style="font-family: monospace;">__cdecl</span>
|
||||
is the default calling convention. To be considered compatible, two
|
||||
function types must either be declared with the same calling
|
||||
convention, or both must leave it unspecified.<br><br></li><li>As I have been threatening for some time, using <span style="font-family: monospace;">__new__</span>
|
||||
as the name of the initialisation method of an extension type has
|
||||
become an error rather than just a warning. In some future release, <span style="font-family: monospace;">__new__</span> will re-emerge with more Python-like semantics.</li></ul><br></body></html>

Pyrex - Installation Instructions
|
||||
=================================
|
||||
|
||||
You have two installation options:
|
||||
|
||||
(1) Run the setup.py script in this directory
|
||||
as follows:
|
||||
|
||||
python setup.py install
|
||||
|

This will install the Pyrex package
|
||||
into your Python system.
|
||||
|
||||
OR
|
||||
|
||||
(2) If you prefer not to modify your Python
|
||||
installation, arrange for the directory
|
||||
containing this file (INSTALL.txt) to be in
|
||||
your module search path.
|
||||
|
||||
For example, create a pyrex.pth file in your
|
||||
Python installation's Lib/site-packages
|
||||
directory and insert a line containing the
|
||||
fully qualified path to the directory containing
|
||||
this file.
|
||||
|
||||
On unix, also put the bin directory on your PATH.
|
||||
|
||||
On Win32 copy the pyrexc.py file to your Python
|
||||
installation's Scripts directory, which should
|
||||
already be on the PATH.

|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but not
|
||||
limited to compiled object code, generated documentation, and

|
||||
"Work" shall mean the work of authorship, whether in Source or Object
|
||||
form, made available under the License, as indicated by a copyright
|
||||
notice that is included in or attached to the work (an example is
|
||||
provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the
|
||||
purposes of this License, Derivative Works shall not include works
|
||||
that remain separable from, or merely link (or bind by name) to the
|
||||
interfaces of, the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including the
|
||||
original version of the Work and any modifications or additions to
|
||||
that Work or Derivative Works thereof, that is intentionally submitted
|

to Licensor for inclusion in the Work by the copyright owner or by an
|
||||
individual or Legal Entity authorized to submit on behalf of the
|
||||
copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent to
|
||||
the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control
|
||||
systems, and issue tracking systems that are managed by, or on behalf
|
||||
of, the Licensor for the purpose of discussing and improving the Work,
|
||||
but excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of, publicly
|
||||
display, publicly perform, sublicense, and distribute the Work and
|
||||
such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except
|
||||
as stated in this section) patent license to make, have made, use,
|
||||
offer to sell, sell, import, and otherwise transfer the Work, where
|
||||
such license applies only to those patent claims licensable by such
|
||||
Contributor that are necessarily infringed by their Contribution(s)
|
||||
alone or by combination of their Contribution(s) with the Work to
|
||||
which such Contribution(s) was submitted. If You institute patent
|
||||
litigation against any entity (including a cross-claim or counterclaim
|
||||
in a lawsuit) alleging that the Work or a Contribution incorporated
|
||||
within the Work constitutes direct or contributory patent
|
||||
infringement, then any patent licenses granted to You under this
|
||||
License for that Work shall terminate as of the date such litigation
|
||||
is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the Work
|
||||
or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You meet
|
||||
the following conditions:
|
||||
|
||||
1. You must give any other recipients of the Work or Derivative Works
|
||||
a copy of this License; and
|
||||
|
||||
2. You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
3. You must retain, in the Source form of any Derivative Works that
|
||||
You distribute, all copyright, patent, trademark, and attribution
|
||||
notices from the Source form of the Work, excluding those notices that
|
||||
do not pertain to any part of the Derivative Works; and
|
||||
|
||||
4. If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained within
|
||||
such NOTICE file, excluding those notices that do not pertain to any
|
||||
part of the Derivative Works, in at least one of the following places:
|
||||
within a NOTICE text file distributed as part of the Derivative Works;
|
||||
within the Source form or documentation, if provided along with the
|
||||
Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The
|
||||
contents of the NOTICE file are for informational purposes only and do
|
||||
not modify the License. You may add Your own attribution notices
|
||||
within Derivative Works that You distribute, alongside or as an
|
||||
addendum to the NOTICE text from the Work, provided that such
|
||||
additional attribution notices cannot be construed as modifying the
|
||||
License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may
|
||||
provide additional or different license terms and conditions for use,
|
||||
reproduction, or distribution of Your modifications, or for any such
|
||||
Derivative Works as a whole, provided Your use, reproduction, and
|
||||
distribution of the Work otherwise complies with the conditions stated
|
||||
in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work by
|
||||
You to the Licensor shall be under the terms and conditions of this
|
||||
License, without any additional terms or conditions. Notwithstanding
|
||||
the above, nothing herein shall supersede or modify the terms of any
|
||||
separate license agreement you may have executed with Licensor
|
||||
regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or agreed
|
||||
to in writing, Licensor provides the Work (and each Contributor
|
||||
provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR
|
||||
CONDITIONS OF ANY KIND, either express or implied, including, without
|
||||
limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
|
||||
MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely
|
||||
responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your
|
||||
exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise, unless
|
||||
required by applicable law (such as deliberate and grossly negligent
|
||||
acts) or agreed to in writing, shall any Contributor be liable to You
|
||||
for damages, including any direct, indirect, special, incidental, or
|
||||
consequential damages of any character arising as a result of this
|
||||
License or out of the use or inability to use the Work (including but
|
||||
not limited to damages for loss of goodwill, work stoppage, computer
|
||||
failure or malfunction, or any and all other commercial damages or
|
||||
losses), even if such Contributor has been advised of the possibility
|
||||
of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer, and
|
||||
charge a fee for, acceptance of support, warranty, indemnity, or other
|
||||
liability obligations and/or rights consistent with this License.
|
||||
However, in accepting such obligations, You may act only on Your own
|
||||
behalf and on Your sole responsibility, not on behalf of any other
|
||||
Contributor, and only if You agree to indemnify, defend, and hold each
|
||||
Contributor harmless for any liability incurred by, or claims asserted
|
||||
against, such Contributor by reason of your accepting any such
|
||||
warranty or additional liability.

|
||||
Lexicon(specification) builds a lexical analyser from the given
|
||||
|specification|. The specification consists of a list of
|
||||
specification items. Each specification item may be either:
|
||||
|
||||
1) A token definition, which is a tuple:
|
||||
|
||||
(pattern, action)
|
||||
|
||||
The |pattern| is a regular axpression built using the
|
||||
constructors defined in the Plex module.
|
||||
|
||||
The |action| is the action to be performed when this pattern
|
||||
is recognised (see below).
|
||||
|
||||
2) A state definition:
|
||||
|
||||
State(name, tokens)
|
||||
|
||||
where |name| is a character string naming the state,
|
||||
and |tokens| is a list of token definitions as
|
||||
above. The meaning and usage of states is described
|
||||
below.
|
||||
|
||||
Actions
|
||||
-------
|
||||
|
||||
The |action| in a token specication may be one of three things:
|
||||
|
||||
1) A function, which is called as follows:
|
||||
|
||||
function(scanner, text)
|
||||
|
||||
where |scanner| is the relevant Scanner instance, and |text|
|
||||
is the matched text. If the function returns anything
|
||||
other than None, that value is returned as the value of the
|
||||
token. If it returns None, scanning continues as if the IGNORE
|
||||
action were specified (see below).
|
||||
|
||||
2) One of the following special actions:
|
||||
|
||||
IGNORE means that the recognised characters will be treated as
|
||||
white space and ignored. Scanning will continue until
|
||||
the next non-ignored token is recognised before returning.
|
||||
|
||||
TEXT causes the scanned text itself to be returned as the
|
||||
value of the token.
|
||||
|
||||
3) Any other value, which is returned as the value of the token.
|
||||
|
||||
States
|
||||
------
|
||||
|
||||
At any given time, the scanner is in one of a number of states.
|
||||
Associated with each state is a set of possible tokens. When scanning,
|
||||
only tokens associated with the current state are recognised.
|
||||
|
||||
There is a default state, whose name is the empty string. Token
|
||||
definitions which are not inside any State definition belong to
|
||||
the default state.
|
||||
|
||||
The initial state of the scanner is the default state. The state can
|
||||
be changed in one of two ways:
|
||||
|
||||
1) Using Begin(state_name) as the action of a token.
|
||||
|
||||
2) Calling the begin(state_name) method of the Scanner.
|
||||
|
||||
To change back to the default state, use '' as the state name.

Pyrex - Usage Instructions
|
||||
==========================
|
||||
|
||||
Building Pyrex extensions using distutils
|
||||
-----------------------------------------
|
||||
|
||||
Pyrex comes with an experimental distutils extension for compiling
|
||||
Pyrex modules, contributed by Graham Fawcett of the University of
|
||||
Windsor (fawcett@uwindsor.ca).
|
||||
|
||||
The Demos directory contains a setup.py file demonstrating its use. To
|
||||
compile the demos:
|
||||
|
||||
(1) cd Demos
|
||||
|
||||
(2) python setup.py build_ext --inplace
|
||||
|
||||
or
|
||||
|
||||
python setup.py build --build-lib=.
|
||||
|
||||
(You may get a screed of warnings from the C compiler, but you can
|
||||
ignore these -- as long as there are no actual errors, things are
|
||||
probably okay.)
|
||||
|
||||
Try out the extensions with:
|
||||
|
||||
python run_primes.py
|
||||
python run_spam.py
|
||||
python run_numeric_demo.py
|
||||
|
||||
|
||||
Building Pyrex extensions by hand
|
||||
---------------------------------
|
||||
|
||||
You can also invoke the Pyrex compiler on its own to translate a .pyx
|
||||
file to a .c file. On Unix,
|
||||
|
||||
pyrexc filename.pyx
|
||||
|
||||
On other platforms,
|
||||
|
||||
python pyrexc.py filename.pyx
|
||||
|
||||
It's then up to you to compile and link the .c file using whatever
|
||||
procedure is appropriate for your platform. The file
|
||||
Makefile.nodistutils in the Demos directory shows how to do this for
|
||||
one particular Unix system.
|
||||
|
||||
|
||||
Command line options
|
||||
--------------------
|
||||
|
||||
The pyrexc command supports the following options:
|
||||
|
||||
Short Long Argument Description
|
||||
-----------------------------------------------------------------------------
|
||||
-v --version Display version number of pyrex compiler
|
||||
-l --create-listing Write error messages to a .lis file
|
||||
-I --include-dir <directory> Search for include files in named
|
||||
directory (may be repeated)
|
||||
-o --output-file <filename> Specify name of generated C file (only
|
||||
one source file allowed if this is used)
|
||||
|
||||
Anything else is taken as the name of a Pyrex source file and compiled
|
||||
to a C source file. Multiple Pyrex source files can be specified
|
||||
(unless -o is used), in which case each source file is treated as the
|
||||
source of a distinct extension module and compiled separately to
|
||||
produce its own C file.

Description: compile native-code modules for Python from Python-like syntax
|
||||
Pyrex lets you write code that mixes Python and C data types any way you want,
|
||||
and compiles it into a C extension for Python.
|
||||
.
|
||||
You can get very large speedups for tasks that don't need all the dynamic
|
||||
features of Python, with very small differences in syntax and much less
|
||||
hassle than writing your modules from scratch in C.

||||
.
|
||||
This Emacs mode is derived from the Python language mode, python-mode,
|
||||
and provides syntax highlighting for Pyrex scripts.

|

.RI " files" ...
|
||||
.SH DESCRIPTION
|
||||
This manual page documents briefly the
|
||||
.B pyrexc
|
||||
command.
|
||||
This manual page was written for the Debian distribution
|
||||
because the original program does not have a manual page.
|
||||
.PP
|
||||
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
|
||||
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
|
||||
.\" respectively.
|
||||
\fBpyrexc\fP is a python script that converts a .pyx file to C, so it can
|
||||
be compiled for use as a Python module.
|
||||
.PP
|
||||
You then need to compile the .c file along with the include files for
|
||||
Python, and link it into a shared library.
|
||||
.PP
|
||||
The HTML documentation explains this better, and the Demo examples show how
|
||||
to automate the compile and link stages more easily.
