NAME
ldbash -- Dynamic loader for libbash(7) libraries. SYNOPSIS
ldbash [-h | --help] ldbash [-l | --list] ldbash [-L | --load lib,[lib] ...] ldbash [-U | --unload lib,[lib] ...] ldbash [-e | --externlist lib,[lib] ...] ldbash [--externlist-all] ldbash [--i | --internlista lib,[lib] ...] ldbash [--internlist-all] DESCRIPTION
ldbash is used to manipulate libbash(7) libraries. Its main function is to load specific library. It can also print list of available libraries, list functions each library exports, unload functions, etc. In case of --load and --unload ,the output is intended to be passed to bash eval command. Options -h | --help Print options summary -l | --list Display list of available libraries. The libraries names listed, may be passed as parameters to other invocations of ldbash. I.e. first you run ldbash --list to see what is available and then you may load it. -L | --load lib,[lib] ... Load given libraries - i.e. print string that should be passed to eval command. Usually the string contains various source commands. Libraries that given libraries depend on are also loaded. Libraries only loaded if their dependencies are satisfied. Dependencies are resolved using ldbash.cache file, which is created by ldbashconfig(8). -U | --unload lib,[lib] ... Unload given libraries, but not their dependencies. The output should be passed to eval command (in the same manner as with --load ). -e | --externlist lib,[lib] ... List all symbols that are exported by given libraries. Symbols are usually functions that given libraries implement. --externlist-all List all exported symbols of all available libraries. Symbols are usually functions that library implement. -i | --internlist lib,[lib] ... List all internal symbols (i.e. global variables/functions) of given libraries. This is intended mostly for developers that want to develop library of their own, and want to be sure that they don't override any already defined symbol. --internlist-all List all internal symbols of all available libraries. This is intended mostly for developers that want to develop library of their own, and want to be sure that they don't override any already defined symbol. FILES
/etc/ldbash.cache Cache file that contains information about libraries dependencies and list of exported symbols. See ldbashconfig((8)) for further details. BUGS
The script can't load libraries if their file name starts with '-'. (If someone uses file names that start with a '-' he/she deserves it!) AUTHORS

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. 4. See html manual for full version of this guide. AUTHORS
