TengoModifyMessage allows you to specify the location of a tengo (https://github.com/d5/tengo/) script. This script will receive every incoming message and can be used to modify the Username and the Text of that message. The script will have the following global variables: to modify: msgUsername and msgText to read: msgChannel and msgAccount The script is reloaded on every message, so you can modify the script on the fly. Example script can be found in https://github.com/42wim/matterbridge/tree/master/gateway/bench.tengo and https://github.com/42wim/matterbridge/tree/master/contrib/example.tengo The example below will check if the text contains blah and if so, it'll replace the text and the username of that message. text := import("text") if text.re_match("blah",msgText) { msgText="replaced by this" msgUsername="fakeuser" } More information about tengo on: https://github.com/d5/tengo/blob/master/docs/tutorial.md and https://github.com/d5/tengo/blob/master/docs/stdlib.md
