Hi there. I've developed a module for scripting at Broadcom, and I received permissions to publish it to CPAN. The module is "unifdef+". It's functionality is based on the bash utility unifdef, but it's a bit more advanced (it simplifies the precompiler conditionals for example, and has support to process dependencies in Kconfig files, and some limited support for Makefiles, which still needs work). It would be good to push upstream, as it is very useful for feature tracking.
I was reading through http://engineering.tilt.com/lessons-learned-cpan/ and they suggested I email this address to figure out the best name for this module. Currently, it exists as UnifdefPlus.pm, which is invoked from some wrappers: unifdef+.pl, unkconfig.pl and unmakefile.pl. The usage for unifdef+ is as follows: Usage: unifdef+ [options] file unifdef+ [options] -F file unifdef+ [options] [-I file] [-O file] unifdef+ --version Options: -D name[=val] declare name as defined. All compiler directives related to name will be simplified as if name was defined as val. If val is not specified, a value of 'y' will be assumed. This option may be repeated multiple times. -U name declare name as undefined. All compiler directives related to name will be simplified as if name was undefined. This option may be repeated multiple times. -I filename Take input from filename -O filename Send output to filename -F filename Modify filename --simplifiedonly Only output lines within a simplified #if/#elif/#else/#endif clause --dbg run with debugging enabled --version outputs the current version of unifdef+ Description: The unifdef+ utility is designed to simplify c and cpp files based on preprocessor conditionals. It has the ability to expand and simplify preprocessor conditionals ( #if, #ifdef, #elif, #else, #endif statements) based on the values passed in on the command line. If a preprocessor conditional contains any of the macros specified on the command line, unifdef+ will substitute the known values and then proceed to simplify the expression. If the condition resolves to either true or false, all unused code is removed from the output. Otherwise, the condition is replaced with the simplified version in the output. Exit Status: The exit status will be 0 if the input has not been modified, 1 if there are modifications, or 2 if there is an error processing the input. Example: unifdef+ -U CC_FEATURE1 -D CC_VER=12 -D CC_FEATURE2=y somefile.c Thanks, John
