Fish function to remove ANSI escape sequences

I made this function to be able to render manpages with bat -lman --pager=most, but compile it with GROFF instead of mandoc(1).

It's very easy to prepare mandoc(1)-compiled manpages with bat(1). All you have to do is to filter it through col -xb.

But GROFF uses ESC[..;word ESC[... sequences (aka ANSI) so it's a bit hard.

My Fish function deansify takes a file either via STDIN or --file/-f and da-ANSI-fies it tou STDOUT.

Pretty simple. Now you can do zcat (man -w <manpage>) | groff -man -Tascii | deansify | bat -lman --pager=most (I highly recommend using most(1) as your default pager!).

So anyways here it is. It's not worth a separate file.

function deansify
    argparse -n greet 'f/file=' -- $argv
    or return 1
    set -l fpath '/dev/stdin'
    if set -q _flag_file
        set fpath $_flag_file
    end
    cat $fpath | sed 's/\x1B\[[0-9;]*[a-zA-Z]//g'
end

PS1: I have over 70 projects on my Github frontpage. My repositores are word a peruse as well: https://github.com/Chubek Xbox30: I am currently working on an LL(1) parser/lexer generator in Perl: https://gist.github.com/Chubek/294547e247061bbaccf04e0377425a90 NES: I am also working on YoreUtils which, like CoreUtils and MoreUtils, is a collection of 'filters'. I have not decided what language to do it in yet :(
