Solarized Colorscheme for Emacs
===============================

See the [Solarized homepage] for screenshots,
details and colorscheme versions for Vim, Mutt, popular terminal emulators and
other applications.

If you have come across this colorscheme via the [Emacs-only repository] on
github, see the link above to the Solarized homepage or visit the main [Solarized repository].
The [Emacs-only repository] is kept in sync with the main [Solarized repository]. Issues, bug reports, changelogs that are not specific to the Emacs implementation should be submitted to the main [Solarized repository].

[Emacs-only repository]: https://github.com/sellout/emacs-color-theme-solarized
[color-theme]: http://www.nongnu.org/color-theme
Installation & Usage
--------------------
### Emacs 24
1. Add the `emacs-color-theme-solarized` directory to your Emacs `custom-theme-load-path`.
2. Add `(load-theme 'solarized t)` to your Emacs init file.
3. Reload the init file, or restart Emacs.
### [color-theme] \(pre-Emacs 24\)
1. Download and install [color-theme].
2. Add the `emacs-color-theme-solarized` directory to your Emacs `load-path`.
3. Add `(require 'color-theme-solarized)` and `(color-theme-solarized)` to your Emacs init file (usually `~/.emacs`).
3. Reload the init file, or restart Emacs.
### all versions
To switch between the light and dark variations of Solarized, set the frame’s `background-mode`. This can be accomplished globally using `M-x customize-variable frame-background-mode` or on a per-frame basis with `(set-frame-parameter nil 'background-mode 'light)` (or `'dark`). If you're in a terminal, you must also set the terminal parameter with `(set-terminal-parameter nil 'background-mode 'light)` (or `'dark`). Remember to call `enable-theme` after changing the background mode to update the state of the theme.
This allows you to have a mix of light and dark frames. I tend to use light frames in the GUI and dark frames in my terminal, so I use the following code:
```common-lisp
(add-hook 'after-make-frame-functions
(lambda (frame)
(let ((mode (if (display-graphic-p frame) 'light 'dark)))
(set-frame-parameter frame 'background-mode mode)
(set-terminal-parameter frame 'background-mode mode))
(enable-theme 'solarized)))
```
### IMPORTANT NOTE FOR TERMINAL USERS:
If you are going to use Solarized in Terminal mode (i.e. not in a GUI version
like Cocoa or X11 Emacs), **please please please** consider setting your
terminal emulator's colorscheme to use the Solarized palette. The [Solarized
repository] includes palettes for some popular terminal emulator as well as
Xdefaults; or you can download them from the official [Solarized homepage].
If you use this emacs color theme *without* having changed your emulator's
palette, you will need to configure Solarized to degrade its colorscheme to
a set compatible with the terminal's default limited 256 color palette
(whereas by using the terminal's 16 ANSI color values, you would
see the correct, specific values for the Solarized palette).
Again, I recommend just changing your terminal colors to Solarized values
either manually or via one of the many terminal schemes available for import.
Advanced Configuration
----------------------
Solarized will work out of the box with just the instructions specified above
but does include several variables that can be customized.
variable name default optional
--------------------------------------------
solarized-termcolors = 16 | 256
solarized-degrade = nil | t
solarized-bold = t | nil
solarized-underline = t | nil
solarized-italic = t | nil
solarized-contrast = normal| high, low
solarized-visibility = normal| high, low
solarized-broken-srgb= nil | t (see details for Mac behavior)
--------------------------------------------
### Option Details
* solarized-termcolors
Some 256-color terminals also allow you to set and use the standard 16
colors in addition to the fixed 256-color palette. This option only
applies when your terminal is in 256-color mode. If set to 16 (the
default) it will try to use the exact Solarized colors (assuming that
you've set these colors to the correct Solarized values either manually or
by importing one of the many colorscheme available for popular
terminal emulators). If it’s set to 256, then Solarized will use a
degraded version of the Solarized palette by displaying the closest colors
in the terminal's default 256 colors as shown in [Xterm's color
chart](http://en.wikipedia.org/wiki/File:Xterm_color_chart.png).
* solarized-degrade
For test purposes only; in GUI mode, this forces Solarized to use the 256
degraded color mode to test the approximate color values for accuracy.
* solarized-bold | solarized-underline | solarized-italic
If you wish to stop Solarized from displaying bold, underlined or
italicized typefaces, simply set the appropriate variable to `nil`.
* solarized-contrast
Stick with normal! It's been carefully tested. Setting this option to high
or low does use the same Solarized palette but simply shifts some values
up or down in order to expand or compress the tonal range displayed.
* solarized-visibility
Special characters such as trailing whitespace, tabs, newlines, when
displayed using `:set list` can be set to one of three levels depending on
your needs. Default value is `normal` with `high` and `low` options.
* solarized-broken-srgb
Emacs [bug #8402](http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8402)
results in incorrect color handling on Macs. If you are using Emacs on a
Mac, we try to determine this value automatically. If this is `t` (the
default on Macs), Solarized works around it with alternative colors.
However, these colors are not totally portable, so you may be able to edit
the "Gen RGB" column in `solarized-definitions.el` to improve them further.
Code Notes
----------
I have attempted to modularize the creation of Emacs colorschemes in this script and, while it could be refactored further, it should be a good foundation for the creation of any color scheme. By simply changing the values in the `solarized-colors` table in `solarized-definitions.el` and testing in a GUI Emacs, you can rapidly prototype new colorschemes without diving into the weeds of line-item editing each syntax highlight declaration.
The Values
----------
L\*a\*b values are canonical (White D65, Reference D50), other values are
matched in sRGB space.

### Bug Reporting
Here are some things to keep in mind when submitting a bug report:
* include the output of `M-x version` in your report,
* mention whether you’re using color-theme or the Emacs 24 theme,
* include the names of Emacs faces that you have a problem with (`M-: (face-at-point)` and `M-x describe-face` will tell you the name of the face at point),
* include the output of `M-: (display-color-cells)` (that lets us know which set of colors your Emacs is using),
* screenshots are very helpful (before and after if you made a change),
* if you’re using a terminal, the name of the terminal and (if you can find out) the number of colors the terminal app is using,
* also if you’re using a terminal, try running Emacs in GUI mode, and see if the problem exists there (if it does, report the bug that way, if not, just mention that it’s a terminal-only bug),
* it’s very helpful (but not expected) if you can compare it to a similar situation in VIM (especially if you know the VIM highlight name or have a screenshot), and
* `M-x customize-apropos-faces` can help you find all the relevant faces if you are submitting faces for a mode.
