function wysiwyg_get_libraries in Wysiwyg 5.2

Same name and namespace in other branches
  1. 6.2 wysiwyg.module \wysiwyg_get_libraries()
  2. 7.2 wysiwyg.module \wysiwyg_get_libraries()

Return an array of library directories.

Returns an array of library directories from the all-sites directory (i.e. sites/all/libraries/), the profiles directory, and site-specific directory (i.e. sites/somesite/libraries/). The returned array will be keyed by the library name. Site-specific libraries are prioritized over libraries in the default directories. That is, if a library with the same name appears in both the site-wide directory and site-specific directory, only the site-specific version will be listed.

Return value

A list of library directories.
