iterm2browser

iterm2browser is a command line tool to convert iterm color schemes to styles you can use in the browser. It outputs css, json, and less variables.

There are 2 types of css output. The first is formatted to be used with ansi_up. The second is formatted to be used with term.js / tty.js

iterm2browser is basically a wrapper around iterm-colors that outputs to template files.

You can find some converted styles here with a demo of them in action.

Install

npm install -g iterm2browser

Usage

Usage: iterm2browser <command> [options] <file/URL> <output>

Options:

  -h, --help           output usage information
  -V, --version        output the version number
  -p, --prefix [name]  Add a prefix to the output
  -a, --append         Append to output file

Commands:

  css      Convert to css
  termjs   Convert to term.js compatible css
  json     Convert to a json representation
  less     Convert to less variables

The prefix command is useful for adding css classes to styles. See output format below.

The append flag will append styles to the output file. Without, it will write over the output file.

Examples

iterm2browser css cobalt2.itermcolors cobalt2.css

iterm2browser css --append ir_black.itermcolors styles.css

iterm2browser less http://github.com/that/style/there that.less

Output Formats

CSS Output
Provides these styles:

• .fg
• .bg
• ::selection
• .ansi-{color}-fg, .ansi-{color}-bg, .ansi-bright-{color}-fg, and .ansi-bright-{color}-bg for black, red, green, yellow, blue, magenta, cyan, and white

Prefixes are applied this pattern: {{ prefix }} .fg

So iterm2browser css --prefix=".cobalt2" cobalt2.itermcolors cobalt2.css would output: .cobalt2 .fg {...}

Termjs Output
You can set termjs colors when you start a terminal with json, but how do you change it on the fly, whenever you want? Nasty hacks, thats how. Termjs css output looks like this:
{{ prefix }} span[style*=";color:#eeeeec;"] {color: {{ theme_color }} !important;}

It works by overriding the default inline styles termjs sets for fg and bg colors. Nasty. It also provides .fg and .bg like the normal css output.

JSON Output
Follows this pattern (without the outer prefix level if it is omitted):

{
  "{{prefix}}": {
    "fg":            "{{ c.foreground }}",
    "bg":            "{{ c.background }}",
    "black":         "{{ c.palette.0 }}",
    "red":           "{{ c.palette.1 }}",
    "green":         "{{ c.palette.2 }}",
    "yellow":        "{{ c.palette.3 }}",
    "blue":          "{{ c.palette.4 }}",
    "magenta":       "{{ c.palette.5 }}",
    "cyan":          "{{ c.palette.6 }}",
    "white":         "{{ c.palette.7 }}",
    "brightBlack":   "{{ c.palette.8 }}",
    "brightRed":     "{{ c.palette.9 }}",
    "brightGreen":   "{{ c.palette.10 }}",
    "brightYellow":  "{{ c.palette.11 }}",
    "brightBlue":    "{{ c.palette.12 }}",
    "brightMagenta": "{{ c.palette.13 }}",
    "brightCyan":    "{{ c.palette.14 }}",
    "brightWhite":   "{{ c.palette.15 }}"
  }
}

LESS Output
Outputs color variables you can use elsewhere.
Follows this format: @{{prefix}}brightRed using the same variable names as the JSON output.

Custom Formats

If you want to add or change a format, you can add or edit a .mustache template in lib/templates. Compile the template with the Hogan's hulk command:

hulk *.mustache > compiled.js

If your template was named mine.mustache, you would then run iterm2browser with the mine command:

iterm2browser mine cobalt2.itermcolors cobalt2.css
