PROGRAM:

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.mkdtemp().

--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.

REQUIREMENTS


Python 1.5.2 or higher (2.x is supported).

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

Optional Numarray 0.9 or higher partially supported.

numpy_distutils from Scipy (can be downloaded from F2PY homepage)
