You can also build golauncher locally with
Note: plugins are standalone binaries and not part of golauncher, you need to install them separately, or if you are developing, use
--plugin-dir to point to a specific plugin directory.
Once you have
golauncher installed you can either run it from the terminal with
golauncher, or either start it from the application menu.
GLOBAL OPTIONS: --theme value [$THEME] --plugin-dir value [$PLUGIN_DIR]
Golauncher takes optionally a theme with
--theme and an additional directory to scan for plugins (
The plugin directory must contains binary prefixed with
golauncher- in order to be loaded.
golauncher is extensible from the bottom up, and indeed the core does provide no functionalities besides the GUI displaying.
Building from source
$ git clone https://github.com/mudler/golauncher $ cd golauncher $ make build
Note that plugins are shipping core functionalities of
golauncher are built separately, in order to build the default plugin set:
$ make -C plugins/ build
This will build the default set of plugins, to try them out you can either run
make test or:
$ mkdir plugin-build $ make DESTDIR=$PWD/plugin-build -C plugins install $ golauncher --plugin-dir plugin-build/usr/local/bin/
Extensions can be written in any language.
golauncher reads binaries starting with
golauncher- prefix inside
$PATH and automatically invokes them while the user is submitting inputs to retrieve results to be displayed to the user. Optionally, golauncher takes a
PLUGIN_DIR environment variable (or
--plugin-dir as args) to specify an additional plugin directory to use.
All the current functionalities of golauncher are split into separate plugins.
Golauncher supports custom themes, you can find examples inside the themes folder.
To run golauncher with a theme, run:
$ THEME=/home/mudler/.golauncher/monokai.yaml golauncher or $ golauncher --theme /home/mudler/.golauncher/monokai.yaml
