NAME

f2py - Fortran to Python interface generator

SYNOPSIS

(1) To construct extension module sources:

f2py [<options>] <fortran files> [[[only:]||[skip:]] <fortran functions> ] [: <fortran files> ...]

(2) To compile fortran files and build extension modules:

f2py -c [<options>, <config_fc options>, <extra options>] <fortran files>

(3) To generate signature files:

f2py -h <filename.pyf> ...< same options as in (1) >

DESCRIPTION

This program generates a Python C/API file (<modulename>module.c) that contains wrappers for given Fortran or C functions so that they can be called from Python. With the -c option the corresponding extension modules are built.

OPTIONS

-h <filename>
Write signatures of the fortran routines to file <filename> and exit. You can then edit <filename> and use it instead of <fortran files>. If <filename>==stdout then the signatures are printed to stdout.
<fortran functions>
Names of fortran routines for which Python C/API functions will be generated. Default is all that are found in <fortran files>.
skip:
Ignore fortran functions that follow until `:'.
only:
Use only fortran functions that follow until `:'.
:
Get back to <fortran files> mode.
-m <modulename>
Name of the module; f2py generates a Python/C API file <modulename>module.c or extension module <modulename>. Default is 'untitled'.
--[no-]lower
Do [not] lower the cases in <fortran files>. By default, --lower is assumed with -h key, and --no-lower without -h key.
--build-dir <dirname>
All f2py generated files are created in <dirname>. Default is tempfile.mktemp().
--overwrite-signature
Overwrite existing signature file.
--[no-]latex-doc
Create (or not) <modulename>module.tex. Default is --no-latex-doc.
--short-latex
Create 'incomplete' LaTeX document (without commands \documentclass, \tableofcontents, and \begin{document}, \end{document}).
--[no-]rest-doc
Create (or not) <modulename>module.rst. Default is --no-rest-doc.
--debug-capi
Create C/API code that reports the state of the wrappers during runtime. Useful for debugging.
-include'<includefile>'
Add CPP #include statement to the C/API code. <includefile> should be in the format of either `"filename.ext"' or `<filename.ext>'. As a result <includefile> will be included just before wrapper functions part in the C/API code. The option is depreciated, use `usercode` statement in signature files instead.
--[no-]wrap-functions
Create Fortran subroutine wrappers to Fortran 77 functions. --wrap-functions is default because it ensures maximum portability/compiler independence.
--help-link [..]
List system resources found by system_info.py. [..] may contain a list of resources names. See also --link-<resource> switch below.
--quiet
Run quietly.
--verbose
Run with extra verbosity.
-v
Print f2py version ID and exit.
--include_paths path1:path2:...
Search include files (that f2py will scan) from the given directories.

CONFIG_FC OPTIONS

The following options are effective only when -c switch is used.
--help-compiler
List available Fortran compilers [DEPRECIATED].
--fcompiler=<name>
Specify Fortran compiler type by vendor.
--compiler=<name>
Specify C compiler type (as defined by distutils)
--fcompiler-exec=<path>
Specify the path to F77 compiler [DEPRECIATED].
--f90compiler-exec=<path>
Specify the path to F90 compiler [DEPRECIATED].
--help-fcompiler
List available Fortran compilers and exit.
--f77exec=<path>
Specify the path to F77 compiler.
--f90exec=<path>
Specify the path to F90 compiler.
--f77flags=...
Specify F77 compiler flags.
--f90flags=...
Specify F90 compiler flags.
--opt=...
Specify optimization flags.
--arch=...
Specify architecture specific optimization flags.
--noopt
Compile without optimization.
--noarch
Compile without arch-dependent optimization.
--debug
Compile with debugging information.

EXTRA OPTIONS

The following options are effective only when -c switch is used.
--link-<resource>
Link extension module with <resource> as defined by numpy_distutils/system_info.py. E.g. to link with optimized LAPACK libraries (vecLib on MacOSX, ATLAS elsewhere), use --link-lapack_opt. See also --help-link switch.
-L/path/to/lib/ -l<libname>
-D<define> -U<name> -I/path/to/include/
<filename>.o <filename>.so <filename>.a
-DPREPEND_FORTRAN -DNO_APPEND_FORTRAN -DUPPERCASE_FORTRAN -DUNDERSCORE_G77
Macros that might be required with non-gcc Fortran compilers.
-DF2PY_REPORT_ATEXIT
To print out a performance report of F2PY interface when python exits. Available for Linux.
-DF2PY_REPORT_ON_ARRAY_COPY=<int>
To send a message to stderr whenever F2PY interface makes a copy of an array. Integer <int> sets the threshold for array sizes when a message should be shown.

Numerical Python 13 or higher (20.x,21.x,22.x,23.x are supported).

Dire qu'une merveille est une chose contraire à l'expérience, revient à
dire qu'elle diffère de l'expérience acquise ou plutôt qu'elle diffère
de cette partie de notre expérience qui a été recueillie, transmise, et
systématisée par les gens compétents. Mais cela signifie simplement que
cette chose est nouvelle, étrange. Plus la merveille est grande, plus
les témoignages en sa faveur doivent être probants.
