Support 256 colors

[andersk]

Because 256 colors ought to be enough for anybody.

This is what keeps me from using mosh for barnowl, so I'd be interested in a fix.

Hmm, why does it keep you from using barnowl? Do you really want the 256 colors, or is something broken?

[keithw]

(Some people seem to have added a line to their .screenrc that tells screen to modify the "xterm" terminfo entry to make it support 256color mode. The line looks like "termcapinfo xterm 'Co#256[...]".

The byobu people sometimes mistakenly recommend this, but it's terribly misguided -- "xterm" only supports the ANSI 8 colors, and this is what mosh advertises. If you want 256color mode, it's fine to use "xterm-256color", but please don't modify the xterm entry, as it will give lousy results on terminals that implement it. I wonder if this is the problem you're having...?)

I had a line like that in my .screenrc (barnowl-256color doesn't seem to display all 256 colors without it). Removing it reverted to the 8 ANSI colors.

I use 50-60 colors at a time in my barnowl and have gotten used to the differentiation this provides.

Instead of putting that in your ~/.screenrc, use this ~/.bashrc snippet to set your TERM to xterm-256color. Then you’ll get 256 colors in ssh+screen+barnowl and a decent fallback to the nearest 16 colors in mosh+screen+barnowl.

I agree, though, that I’d use mosh more if it actually supported 256 colors.

I pushed tentative support for 256 colors to the 256color branch. (It assumes a 256-color local terminal.)

Could you please test and let me know if it works for your applications?

I put the server on linerva and you can get it with --server='athrun mosh_project mosh-server-256-beta'

[ternus]

Works for me. Thanks!

Edit: DOH! I was setting the $TERM on the server but not my local machine. I found my problem using mosh-client -c. Working great now!

Still having problems getting this to work. I tried compiling the server from github and installing the latest client for mac (via the pkg).

I have my $TERM set to xterm-256color (I also tried screen-256color and screen-256color-bce). When running a colortest I'm only seeing 16 colors. If I connect directly via ssh I see the full 256 colors in the colortest.

I've dug around and the only place I can find mention of 256 color support is in some commit messages from a month ago. Any suggestions?

Thanks!
