Triggers

Introduction

Terminix supports the concept of triggers, these are regular expressions defined by the user that when matched against text output by the terminal trigger an action. A trigger consists of a regular expression, the action to execute and a parameter string. Depending on the action, the parameter can not be used at all, a single string or a semi-colon delimited list of variables.

The result of the regular expression can be referenced as tokens in the parameter, Terminix will substitute the tokens in the parameter prior to executing the action. The token $0 refers to the complete regular expression match. If groups were defined in the regular expression, the tokens $1, $2, $3, etc refer to the individual group captures.

Supported Actions

The following actions are supported by Terminix:
