NAME

     libbash — A bash shared libraries package.

DESCRIPTION

     libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash
     scripts whose functions you may want to load and use in scripts of your own.

     It  contains  a  ‘dynamic  loader’  for  the  shared  libraries  (   ldbash(1)),   a   configuration   tool
     (ldbashconfig(8)), and some libraries.

     Using  ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash
     shared library that can be loaded using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with ‘#EXPORT=’.  That line will contain (after the ‘=’) a list
            of functions that the library exports.  I.e. all the function that will be usable after loading that
            library will be listed in that line.

     3.     It must contain a line that begins with ‘#REQUIRE=’.  That line will contain (after the ‘=’) a list
            of bash libraries that are required for our library.  I.e. every bash library that is in use in our
            bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define)
            only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in
            ‘#EXPORT=’) should begin with:
                  __<library_name>_
            For example, internal function myfoosort of hashstash library should be named as
                  __hashstash_myfoosort
            This helps to avoid conflicts in global name space when using libraries that come from different
            vendors.
