Filesystem structure of a Horde 4 application

Each Horde application has a common filesystem structure. This helps organizing the several components of the application and simplifies working with unknown applications.

These are the directories available in every Horde application:

Directory	Content
/	Base directory with the controller scripts called by the browser
bin/	Binary and other standalone CLI scripts
config/	Configuration files
docs/	Administrator documentation
lib/	Application-specific library files
locale/	Original and compiled translations; application help files
migration/	Setup and migration files
templates/	Template files
themes/	Themes directories
themes/default/	Base theme
themes/defaults/graphics/	Base theme icons

Usually there are more directories, depending on the application:

• If there are many controller scripts for an application, they may be grouped into directories under the base directory.
• The lib/ directory has many levels of subdirectories. See Doc/Dev/FrameworkH4 for details.
• The locale/ directory has a subdirectory for each locale, e.g. locale/de/ or locale/zh_TW/ if locale has multiple regions. These subdirectories contain the translated help file help.xml and the directory LC_MESSAGES/ which contains the actual, compiled translation, e.g. imp.mo and original source file, e.g. imp.po.
• The templates/ directory groups all templates for a single controller script into one subdirectory. All templates for a script called list.php are inside templates/list/ for example.
• Each theme has a subdirectory, e.g. themes/bluewhite/; if a theme provides its own icon set, the icons are inside a graphics/ subdirectory, e.g. themes/bluewhite/graphics/.
• Some applications have sub-sets of their icons grouped into subdirectories, e.g. themes/graphics/flags/.
