Solarized Colorscheme for Vim
=============================

details and colorscheme versions for Vim, Mutt, popular terminal emulators and 
other applications.

Downloads
---------

If you have come across this colorscheme via the [Vim-only repository] on 
github, or the [vim.org script] page see the link above to the Solarized 
homepage or visit the main [Solarized repository].

The [Vim-only repository] is kept in sync with the main [Solarized repository] 
and is for installation convenience only (with [Pathogen] or [Vundle], for 
instance).  Issues, bug reports, changelogs are centralized at the main 
[Solarized repository].

Installation
------------

### Option 1: Manual installation

1.  Move `solarized.vim` to your `.vim/colors` directory. After downloading the 
    vim script or package:

        $ cd vim-colors-solarized/colors
        $ mv solarized.vim ~/.vim/colors/

### Option 2: Pathogen installation ***(recommended)***

1.  Download and install Tim Pope's [Pathogen].

2.  Next, move or clone the `vim-colors-solarized` directory so that it is 
    a subdirectory of the `.vim/bundle` directory.

    a. **Clone:** 

            $ cd ~/.vim/bundle
            $ git clone git://github.com/altercation/vim-colors-solarized.git

    b. **Move:**

        In the parent directory of vim-colors-solarized:
        
            $ mv vim-colors-solarized ~/.vim/bundle/

### Modify .vimrc

After either Option 1 or Option 2 above, put the following two lines in your 
.vimrc:

    syntax enable
    set background=dark
    colorscheme solarized

or, for the light background mode of Solarized:

    syntax enable
    set background=light
    colorscheme solarized

I like to have a different background in GUI and terminal modes, so I can use 
the following if-then. However, I find vim's background autodetection to be 
pretty good and, at least with MacVim, I can leave this background value 
assignment out entirely and get the same results.

    if has('gui_running')
        set background=light
    else
        set background=dark
    endif

See the [Solarized homepage] for screenshots which will help you 
select either the light or dark background.

### IMPORTANT NOTE FOR TERMINAL USERS:

If you are going to use Solarized in Terminal mode (i.e. not in a GUI version 
like gvim or macvim), **please please please** consider setting your terminal 
emulator's colorscheme to used the Solarized palette. I've included palettes 
for some popular terminal emulator as well as Xdefaults in the official 
Solarized download available from [Solarized homepage]. If you use 
Solarized *without* these colors, Solarized will need to be told to degrade its
colorscheme to a set compatible with the limited 256 terminal palette (whereas 
by using the terminal's 16 ansi color values, you can set the correct, specific 
values for the Solarized palette).

If you do use the custom terminal colors, solarized.vim should work out of the
box for you. If you are using a terminal emulator that supports 256 colors and 
don't want to use the custom Solarized terminal colors, you will need to use 
the degraded 256 colorscheme. To do so, simply add the following line *before* 
the `colorschem solarized` line:

    let g:solarized_termcolors=256

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 two lines specified above but 
does include several other options that can be set in your .vimrc file.

Set these in your vimrc file prior to calling the colorscheme.
"
    option name               default     optional
    ------------------------------------------------
    g:solarized_termcolors=   16      |   256
    g:solarized_termtrans =   0       |   1
    g:solarized_degrade   =   0       |   1
    g:solarized_bold      =   1       |   0
    g:solarized_underline =   1       |   0
    g:solarized_italic    =   1       |   0
    g:solarized_contrast  =   "normal"|   "high" or "low"
    g:solarized_visibility=   "normal"|   "high" or "low"
    ------------------------------------------------

### Option Details

*   g:solarized_termcolors

    This is set to *16* by default, meaning that Solarized will attempt to use 
    the standard 16 colors of your terminal emulator. You will need to set 
    those colors to the correct Solarized values either manually or by 
    importing one of the many colorscheme available for popular terminal 
    emulators and Xdefaults.

*   g:solarized_termtrans

    If you use a terminal emulator with a transparent background and Solarized 
    isn't displaying the background color transparently, set this to 1 and 
    Solarized will use the default (transparent) background of the terminal 
    emulator. *urxvt* required this in my testing; iTerm2 did not.

    Note that on Mac OS X Terminal.app, solarized_termtrans is set to 1 by 
    default as this is almost always the best option. The only exception to 
    this is if the working terminfo file supports 256 colors (xterm-256color).

*   g:solarized_degrade

    For test purposes only; forces Solarized to use the 256 degraded color mode 
    to test the approximate color values for accuracy.

*   g:solarized_bold | g:solarized_underline | g:solarized_italic

    If you wish to stop Solarized from displaying bold, underlined or 
    italicized typefaces, simply assign a zero value to the appropriate 
    variable, for example: `let g:solarized_italic=0`

*   g: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.

*   g: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.

Toggle Background Function
--------------------------

Solarized comes with a Toggle Background plugin that by default will map to 
<F5> if that mapping is available. If it is not available you will need to 
either map the function manually or change your current <F5> mapping to 
something else.

To set your own mapping in your .vimrc file, simply add the following line to 
support normal, insert and visual mode usage, changing the "<F5>" value to the 
key or key combination you wish to use:

    call togglebg#map("<F5>")

Note that you'll want to use a single function key or equivalent if you want 
the plugin to work in all modes (normal, insert, visual).

Code Notes
----------

Use folding to view the `solarized.vim` script with `foldmethod=marker` turned 
on.

I have attempted to modularize the creation of Vim 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 sixteen values in the 
GUI section and testing in gvim (or mvim) 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.
