Cython (http://cython.org) is a compiler for code written in the
|
||
|
Cython language. Cython is based on Pyrex by Greg Ewing.
|
||
|
|
||
|
Usage: cython [options] sourcefile.{pyx,py} ...
|
||
|
|
||
|
Options:
|
||
|
-V, --version Display version number of cython compiler
|
||
|
-l, --create-listing Write error messages to a listing file
|
||
|
-I, --include-dir <directory> Search for include files in named directory
|
||
|
(multiple include directories are allowed).
|
||
|
-o, --output-file <filename> Specify name of generated C file
|
||
|
-t, --timestamps Only compile newer source files
|
||
|
-f, --force Compile all source files (overrides implied -t)
|
||
|
-v, --verbose Be verbose, print file names on multiple compilation
|
||
|
-p, --embed-positions If specified, the positions in Cython files of each
|
||
|
function definition is embedded in its docstring.
|
||
|
--cleanup <level> Release interned objects on python exit, for memory debugging.
|
||
|
Level indicates aggressiveness, default 0 releases nothing.
|
||
|
-w, --working <directory> Sets the working directory for Cython (the directory modules
|
||
|
are searched from)
|
||
|
--gdb Output debug information for cygdb
|
||
|
--gdb-outdir <directory> Specify gdb debug information output directory. Implies --gdb.
|
||
|
|
||
|
-D, --no-docstrings Strip docstrings from the compiled module.
|
||
|
-a, --annotate Produce a colorized HTML version of the source.
|
||
|
--annotate-coverage <cov.xml> Annotate and include coverage information from cov.xml.
|
||
|
--line-directives Produce #line directives pointing to the .pyx source
|
||
|
--cplus Output a C++ rather than C file.
|
||
|
--embed[=<method_name>] Generate a main() function that embeds the Python interpreter.
|
||
|
-2 Compile based on Python-2 syntax and code semantics.
|
||
|
-3 Compile based on Python-3 syntax and code semantics.
|
||
|
--3str Compile based on Python-3 syntax and code semantics without
|
||
|
assuming unicode by default for string literals under Python 2.
|
||
|
--lenient Change some compile time errors to runtime errors to
|
||
|
improve Python compatibility
|
||
|
--capi-reexport-cincludes Add cincluded headers to any auto-generated header files.
|
||
|
--fast-fail Abort the compilation on the first error
|
||
|
--warning-errors, -Werror Make all warnings into errors
|
||
|
--warning-extra, -Wextra Enable extra warnings
|
||
|
-X, --directive <name>=<value>[,<name=value,...] Overrides a compiler directive
|
||
|
-E, --compile-time-env name=value[,<name=value,...] Provides compile time env like DEF would do.
|
||
|
--module-name Fully qualified module name. If not given, it is deduced from the
|
||
|
import path if source file is in a package, or equals the
|
||
|
filename otherwise.
|
||
|
-M, --depfile Produce depfiles for the sources
|
