GSH scripts, plugins and classes are linked dynamically, when a class/sub/struct is referenced by a sub/class then it is dynamically loaded and linked to the calling sub/class.
When a command is read/entered into gsh it first searches for a plugin by that name and then looks for a script of that name. As the sub or script is loaded, references to classes or structures or subs are linked to the loading object dynamically.
This approach allows the development of small apps that can be combined at compile time into a executable script.
This is the root directory used by gsh to store retrieve data and programs. Most operations involve this directory path.
gsh searches these directories for integrated plugin functions. It searches in the order shown. the $subspath variable can be set to override these directories. /usr/share/gsh/subs contains the default versions, this should be last in the search path. Subs are plugin modules that are loaded dynamically as referenced by shell scripts and programs.
gsh searches these directories for integrated class definitions. It searches in the order shown. the $classpath variable can be set to override these directories. /usr/share/gsh/class contains the default versions, this should be last in the search path. Classes are plugin classes that are loaded dynamically as referenced by shell scripts and programs.
gsh searches these directories for integrated structure definitions. It searches in the order shown. the $structpath variable can be set to override these directories. /usr/share/gsh/struct contains the default versions, this should be last in the search path. Structures are included when referenced by shell scripts, programs, plugins and classes. This is particularly useful for structures or classes that are used by many apps.
gsh searches these directories for executable gsh scripts. It searches in the order shown. These are in fact games, tools etc. The $scriptpath variable can be set to override these directories. /usr/share/gsh/scripts contains the default versions, this should be last in the search path.
scriptpath="~/vars/scripts;~/vars/games;/usr/share/gsh/scripts"
structpath="~/vars/struct;/usr/share/gsh/struct"
