 +----
 +
 +===== Configuration =====
 +
 +You can override the default cache directory ''$HOME/.cache'' in which, besides other non-essential files, thumbnails are stored:
 +
 +
 +  * **D-Bus/ systemd**
 +     * create a file below ''~/.config/environment.d/'' and inside set XDG_CACHE_HOME. E.g:
 +     * ''XDG_CACHE_HOME=$HOME/.my_new_cache''
 +
 +  * **Other**
 +     * Extend  $HOME/.profile, $HOME/.bash_rc or similar
 +     * ''export XDG_CACHE_HOME=$HOME/.my_new_cache''
 +
 +After that, re-login, make sure the variable is set, and check if it works fine.
 +
 +Tumbler has a configuration file ''tumbler.rc'' described in a [[available_plugins#configuration|dedicated page]].
 +
 +----
 +===== Available Plugins =====
 +
 +Tumbler allows to load a number [[:xfce:tumbler:available_plugins:|additional tumbler plugins]] to support different file formats. Most plugins are loaded by default, if the required libraries are provided. 
 +
 +----
 +
 +===== Standards compliance =====
 +
 +
 +Tumbler supports and implements the following standards/specifications:
 +  * [[https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html|XDG Base Directory Specification]]
 +  * [[https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html|Thumbnail Managing Standard]]
 +  * [[https://wiki.gnome.org/Attic/DraftThumbnailerSpec|Thumbnail Management D-Bus Specification]]

 +

 +----
 +
 +===== Debugging Support =====
 +
 +As with all Xfce components, you can [[https://docs.xfce.org/xfce/building#building_the_packages|set debug support at compile time]], but this is more likely to be of interest to developers or package maintainers.
 +
 +To get debug logs at runtime, starting with Tumbler 4.17.0 (first stable release 4.18.0), you can do the following:
 +
 +  pkill tumblerd
 +  G_MESSAGES_PREFIXED= G_MESSAGES_DEBUG=all $(pkg-config --variable=libdir tumbler-1)/tumbler-1/tumblerd
 +
 +[[|Back To Top]]
 +----
 +
 +===== Required packages =====
 +
 +Tumbler depends on the following packages:
 +
 +  * GLib >= 2.66.0
 +
 +Tumbler can optionally use the following packages:
 +
 +  * gdk-pixbuf >= 2.40.0 (various image formats, some of them requiring the installation of optional libraries specific to gdk-pixbuf; also required for all other plugins below)
