configuration for using solarized theme with crosh

If you are running ChromeOS, have a minimal chroot installed (no X), are working with it using mostly tmux/screen + editor of choice + other terminal tools, then this is a quick guide to set crosh up to properly use the solarized colorscheme. We do this by configuring crosh through the javascript console (ctrl+shift+j).

First (optional?) set crosh to 256 color mode by opening crosh, and entering the javascript console. Set $TERM:

term_.prefs_.set('environment', { TERM: "xterm-256color" })

(not sure about the importance of this step, and screen-256color could probably work the same. I use tmux, and it's working with this.)

Secondly, set $TERM for your chroot session, in your .bashrc, .zshenv, whatever..

export TERM=screen-256color

or xterm-256color if you aren't using tmux/screen.

Thirdly, (optional) it's a good idea to force tmux into 256 color mode, so I have it aliased (.zshenv):

alias tmux="tmux -2"

Now, we need to configure the colors for crosh:

base03 =     "#002b36";
base02 =     "#073642";
base01 =     "#586e75";
base00 =     "#657b83";
base0 =      "#839496";
base1 =      "#93a1a1";
base2 =      "#eee8d5";
base3 =      "#fdf6e3";
yellow =     "#b58900";
orange =     "#cb4b16";
red =        "#dc322f";
magenta =    "#d33682";
violet =     "#6c71c4";
blue =       "#268bd2";
cyan =       "#2aa198";
green =      "#859900";

term_.prefs_.set('color-palette-overrides',
        [ base02 , red     , green  , yellow,
        blue     , magenta , cyan   , base2,
        base03   , orange  , base01 , base00,
        base0    , violet  , base1  , base3 ]);

This overrides the default color-palette with the palette matching the dark solarized colorscheme. In vim (or equivalent), set background=light should now work.

Customizing crosh

Here are some useful things. '...' usually means you can put some CSS-readable value, f.ex. '#bababa'.

Remove scrollbar? term_.prefs_.set('scrollbar-visible', false);

Disable bold? term_.prefs_.set('enable-bold', false)

Change foreground, background or cursor color: term_.prefs_.set('foreground-color', '...')

Blinking cursor? term_.prefs_.set('cursor-blink', false)

Screwed something up? Globally undo everything you changed: term_.prefs_.resetAll()

Some documentation is available here.
