Filesystem structure of a Horde application

This information is valid for Horde 3 only. See Doc/Dev/Filesystem for Horde 4 and later.

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
config/	Configuration files
docs/	Administrator documentation
lib/	Application-specific library files
locale/	Compiled translations and help files
po/	Translations
scripts/	CLI scripts for setup and maintenance
scripts/sql/	SQL scripts for setup
scripts/upgrades/	CLI and SQL scripts for upgrades
templates/	Template files
themes/	Base stylesheet and theme directories
themes/graphics/	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/FrameworkH3? for details.
• The locale/ directory has a subdirectory for each locale, e.g. locale/de_DE/. These subdirectories contain the translated help file help.xml and the directory LC_MESSAGES/ which contains the actual, compiled translation, e.g. imp.mo.
• The scripts/ directory may contain other directories for special purposes, e.g. ldap/.
• 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/.
