===== CLI =====

GroIMP can be started without its graphical interface, with a CLI. Unlike the Headless mode, the CLI enables interaction with multiple the models during run time including opening and closing models, running simulations, editing RGG files etc. Its a valuable feature especially on remote server or for small changes. It syntax of the commands is oriented on basic linux command.

===== Installation & Execution =====

The CLI can be installed using the GroIMP [[01_user_documentation:03_interacting_with_groimp:02_panels:14_plugin_manager|plugin manager]] (which also works in [[01_user_documentation:user-guide:pluginmanager#usage_from_commandline|headless]] or compiled from [[https://gitlab.com/grogra/groimp-plugins/CLI|source]].  

To start the CLI application in a terminal the additional parameter -a cli is needed:

<code bash>
java -Xverify:none -jar core.jar --headless -a cli
</code>

The name core.jar can variate based on the way GroIMP was installed.



===== Structure =====

==== Projects ====

The CLI can be used to manage multiple workbenches. The currently used workbench is defined in the prefix of the command line:
 [**myProject**]%%>>%%

After starting the CLI the first workbench is always "base", which is similar to the empty window when starting the GUI. This workbench cant do much more then creating or opening other projects.

==== Commands ====

The commands to interact with GroIMP and the proejcts are sorted by level of usage. There is currently three levels: 

  * application for managing the different projects and for basic interaction with the operation system
  * window for managing the panels(the cli version) of the current workbench
  * workbench for editing and execution the current project as well general project management

The list can be found below.

===== List of Commands =====

The commands are sorted by level of usage. There is currently three levels: at application, window, or workbench level. The first character of a command indicates at which level it should be executed. 

**Note: the command ''$help'' lists most of the available commands with a description**
