Question

am not getting colorized output

I installed this plugin per instructions, using fisher.

If I do man less, I don't get any color.

If I add cless git help log, also per docs, I also don't get any color.

I'm a fish newbie, but any tips on where to look?

Hi, can you give me the output if functions man please?

And what OS are you running on?

My guesses right now

Your OS doesn't use termcap (https://unix.stackexchange.com/questions/108699/documentation-on-less-termcap-variables)
Your man is not configured to use LESS

I'm on Fedora Linux, 34 beta to be specific.

Oh, and output:

functions man
# Defined in /home/bruce/.config/fish/functions/man.fish @ line 1
function man --description 'Run man with added colors'
    cless /usr/bin/man $argv
end

If I do this, I get colors, however ~~but with some funky artifacts~~:

set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"
set -x MANROFFOPT "-c"

Hi, that is very strange. When you do set -x MANPAGER "sh -c 'col -bx | bat -l man -p'", you are configuring your man to use bat, which provides color out of the box, so that is not using this plugin.
I think it's possible your binary at /usr/bin/man is not using LESS for its paging. Can you try removing set -x MANPAGER "sh -c 'col -bx | bat -l man -p'" and then testing your environment to see if there's still a MANPAGER var being set?

Worst case, you could try this other fish plugin that does almost the same thing: https://github.com/decors/fish-colored-man

It is very strange.

I dropped out of fish to the default bash shell, and PAGER and MANPAGER are not set.

Pretty sure less is default on Fedora, but I have no idea how to confirm that!

In any case, I'll close this; I'll figure something out; the bat solution seems good ATM.

Thanks!

I'm guessing it's because you need to set this env like I did, also on Fedora:

export GROFF_NO_SGR=1

...as mentioned here in the comments:

man-colored-fish sets that for Fedora as well:
