Hello Tim, Op 30-12-17 om 12:58 schreef address@hidden:
1) I suspect that the eight basic colours that can be selected — white, black, red, blue, green, yellow, magenta, and cyan — map directly (and numerically) to the terminal palette (which, in my case, is GNOME Terminal 3.18.3 on Ubuntu 16.04.3). If that's the case, then the /only/ way I can manipulate the palette is to do so at the terminal level — correct?
Correct. There are two patches that add support for 256 colors, though: https://savannah.gnu.org/patch/?8553 https://savannah.gnu.org/patch/?6873 So... if you find nano lacking in color, you could brush one of those up and start lobbying for its inclusion. :)
2) I'm familiar with Perl regular expressions, but the regexes used in syntax files seem to be a tad different. I gather from the docs that they are 'extended regular expressions'. Am I to understand from this that we have/full/ support of everything in Chapter 3 of the /GNU Grep 3 Manual/ (http://www.gnu.org/software/grep/manual/grep.html#Regular-Expressions)?
Right. Although I don't see mention of \` and \' there, so the following may be a more complete summary: https://www.gnu.org/software/gnulib/manual/html_node/egrep-regular-expression-syntax.html Benno
