The ^[ blahblahblah ^G ANSI escape (^[ == ESC, as many VIers and some EMACSers already know) sequence allows a program to change the terminal's color. Mutt uses it to change the colors of various things, including its own messages. You only need to include it in your regexps if you have mutt color its own messages (which includes coloring PGP output, attachments, autoview output, etc.). I'm starting to think that coloring messages should be done by a display_filter rather than Mutt itself, since these types of filtering ops shouldn't really have to mess with control characters ... I guess when you ask why I miss ELM, I have to answer that it liked going to extremes to delegate functionality to separate programs, whereas Mutt sometimes tries to do a tad too much all by itself, IMHO. . . > I > didn't investigate any further than to recognize the need to fix my > sed expressions. Truth be told, that won't quite fix the issue once and for all, either. In cases where only Mutt's message is colored but the rest isn't, there will be an ANSI reset color change escape sequence at the end of the line, so you'll need another ^[ blablablah ^G pattern at the end, before the EOL marker. However, Allister's version (getting rid of the SOL and EOL markers altogether) solves both problems quite nicely, as long as nobody tries to talk about the [-- blah --] stuff in his email ;-) If you insist on solving the problem correctly, you need to figure out the codes Mutt generates under your particular config, put them into the regexp, and disable convert_meta in your config. That way, your filter will only kill [-- blah --] sequences generated by Mutt. A shortcut way (if you don't mind losing [-- blah --] sequences in email) is to make the ANSI sequences at the start and end optional in your regexp. HTH, - Dave -- Uncle Cosmo, why do they call this a word processor? It's simple, Skyler. You've seen what food processors do to food, right? Please visit this link: http://rotter.net/israel
