To change this set the `prefix` during built, e.g. `meson build --buildtype release -Dprefix=$HOME/.local/`. - -Plugins will be installed into the same directory and from thereon will be selected automatically depending on their precedence. This behaviour can be overridden at runtime by setting the environment variable `LIBDECOR_PLUGIN_DIR` and pointing it to a directory with a valid plugin. - -### Debug and Development Builds - -During development and when debugging, it is recommended to enable the AddressSanitizer and increase the warning level: -1. `meson build -Dinstall_demo=true -Db_sanitize=address -Dwarning_level=3` -2. `meson compile -C build` - -You may have to install `libasan6` (apt) or `libasan` (dnf). Otherwise linking will fail. - -By default `libdecor` will look for plugins in the target directory of the installation. Therefore, when running the demos directly from the `build` directory, no plugins will be found and the fallback plugin without any decorations will be used. - -On Meson 0.58.0 and above, this can be corrected using `devenv`, i.e., to run the demo: - -`meson devenv -C build libdecor-demo` - -On older Meson versions, the search path for plugins can be overridden by the environment variable `LIBDECOR_PLUGIN_DIR`. To use the `cairo` plugin, point to the plugin directory: - -`export LIBDECOR_PLUGIN_DIR=build/src/plugins/cairo/` - -and run the demo: - -`./build/demo/libdecor-demo`. - - -### Code of Conduct - -libdecor follows the Contributor Covenant, found at: -https://www.freedesktop.org/wiki/CodeOfConduct - -Please conduct yourself in a respectful and civilised manner when interacting -with community members on mailing lists, IRC, or bug trackers.
