Arg_parser is an argument parser that follows POSIX and GNU conventions for
|
|
command line arguments. There exist C++ and C versions of Arg_parser. The
|
|
C++ version is implemented as a C++ class, while the C version is
|
|
implemented as a single struct plus associated functions. Both are simpler,
|
|
easier to use, and safer than 'getopt_long'.
|
|
|
|
For maximum stability, Arg_parser is self-contained. It extracts all the
|
|
information it needs from its arguments to avoid refering to them later.
|
|
This avoids index-out-of-bounds errors.
|
|
|
|
Arg_parser does not modify its arguments, nor uses any global variables. So
|
|
you may create more than one parser in your program if you need or want to.
|
|
|
|
The C++ version of Arg_parser can also parse options from configuration
|
|
files.
|
|
|
|
To use Arg_parser in your own programs simply copy the files 'arg_parser.h'
|
|
and 'arg_parser.cc' (or 'carg_parser.h' and 'carg_parser.c' for the
|
|
C version) in your source tree. See the file 'main.cc' ('cmain.c') for an
|
|
example of use.
|
|
|
|
Arg_parser was developed as the argument parser for GNU moe, because moe's
|
|
argument parsing is rather complex. Then I used it in my other projects,
|
|
including GNU ddrescue, GNU ed, lzip, GNU ocrad, tarlz, and zutils, with
|
|
excellent results.
