You make take it as is, or you may further work on it, if you think that is still needed. Thank you! I translated the regexps to rx (which I personally find more maintainable and has plenty of precedence in this context) and tightened them up further. They are now anchored at beginning-of-line again, and file names cannot start with whitespace (for disambiguation and speed). I also removed the part that matches the actual message text since it isn't needed, and it would highlight (with an underline in the standard theme) the whole text which is a bit ungainly to read. If the message is multi-line, which earlier examples in this discussions indicated might be the case, then only the first would be highlighted this way which wasn't ideal either. Patch attached, please tell me what you think. Does tsc distinguish between warnings, errors, and 'informational' messages (such as locations of interest that are not errors in their own right)? The examples you supplied all had the word "error" in a prominent place. It would be possible to join the two tsc rules into a single one which would be slightly faster, but having them separate could also be an advantage since it would allow for them to be disabled individually in case of clashes.
