Cobalt2

A Sublime Text theme based on our old blue friend cobalt.

A refined colour scheme that is easy on the eyes and takes small UI elements into account. Includes full Sublime Text theme (sidebar, search, tabs, etc...) as well as support for SublimeLinter, git diffing and a growing number of plugins.

See below for examples. Read more at http://wesbos.com/cobalt2-theme-sublime-text-2/

Installation

Open package control tools → Command Palette and type Install Package
Search for Cobalt2 and hit enter

Penultimately, open Preferences → Settings - User. Add the following lines. Only the first two are required but I recommend using all of them:

"color_scheme": "Packages/Theme - Cobalt2/cobalt2.tmTheme",
"theme": "Cobalt2.sublime-theme",   
"highlight_line": true,
"indent_guide_options": [ "draw_normal", "draw_active" ],
 "highlight_modified_tabs": true,
 "line_padding_bottom": 1,
 "line_padding_top": 1,
 "wide_caret": true,
 "caret_extra_bottom": 2,
 "caret_extra_top": 2,
 "caret_extra_width": 3,
 "caret_style": "phase",
 "bold_folder_labels": true,

Finally, restart Sublime for the Theme to be fully applied.

color_scheme defines how the code looks and theme defines how the sidebar, tabs, search, command palette work.

Options

Sidebar Font Size

Change the sidebar's font size by using these settings in your user config:

{
"sidebar_font_big": true,
"sidebar_font_small": true
}

Sidebar Padding

Adjust the sidebar's padding by using these settings in your user config:

{
"sidebar_medium": true,
"sidebar_large": true,
"sidebar_xlarge": true
}

Requirements

For sidebar icons, you need to be running the latest version of Sublime Text 3 - this feature is very new and not supported in older versions of Sublime Text.

While Cobalt2 covers all languages, I write mostly JavaScript and CSS so I welcome any additions for other languages.
