Top Forums Programming Which language is best suited for regular expressions perl,python.ruby ? Post 302416024 by figaro on Saturday 24th of April 2010 11:29:23 AM

I would like to approach it from the opposite direction: if you master regular expressions well enough and know from your architect what the target language is, you are in a much better position to understand how you can implement the requirements. We routinely develop prototypes with regular expressions in Javascript and ask our developers to implement it on the target environment. The language then turns out to be much less of an issue, since the prototype regex can usually be copied with some syntactical modifications.

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --extension-suffix ] [ --configdir ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --extension-suffix print suffix used for extension modules (including the _d modified for debug builds). --configdir prints the path to the configuration directory under which the Makefile, etc. can be found). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
