mu script [options] [<pattern>]
mu <script-name> [<script-options>]
mu script is the mu command to list available mu scripts. The scripts are to be implemented in the Guile programming language, and therefore only work if your mu is built with support for Guile. In addition, many scripts require you to have gnuplot installed.
Without any parameters, mu script lists the available scripts. If you provide a pattern (a regular expression), only the scripts whose name or one-line description match this pattern are listed. See the examples below.
mu ships with a number of scripts.
when listing the available scripts, show the long descriptions.
-- all options on the right side of the -- are passed to the script.
List all available scripts (one-line descriptions):
$ mu script
List all available scripts matching month (long descriptions):
$ mu script -v month
Run the msgs-per-month script for messages matching 'hello', and pass it the --textonly parameter:
$ mu msgs-per-month --query=hello --textonly
mu script returns 0 when all went well, and returns some non-zero error code when this is not the case.
You can make your own Scheme scripts accessible through mu script by putting them in <muhome>/scripts (which is typically ~/.mu/scripts). It is a good idea to document the scripts by using some special comments in the source code:
;; INFO: this is my script -- one-line description ;; INFO: (longer description) ;; INFO: --option1=<foo> (describe option1) ;; INFO: etc.
