1. INTRODUCTION *indent-guides-introduction*
Indent Guides is a plugin for visually displaying indent levels in Vim.
This plugin should work with gVim out of the box, no configuration needed.
Features:~
* Can detect both tab and space indent styles.
* Automatically inspects your colorscheme and picks appropriate colors (gVim
only).
* Will highlight indent levels with alternating colors.
* Full support for gVim and basic support for Terminal Vim.
* Seems to work on Windows gVim 7.3 (haven't done any extensive tests
though).
* Customizable size for indent guides, eg. skinny guides (soft-tabs only).
* Customizable start indent level.
* Highlight support for files with a mixture of tab and space indent styles.
==============================================================================
2. COMMANDS *indent-guides-commands*
------------------------------------------------------------------------------
:IndentGuidesToggle *:IndentGuidesToggle*
Toggles the indent guides on and off.
------------------------------------------------------------------------------
:IndentGuidesEnable *:IndentGuidesEnable*
Enables the indent guides for the current buffer and any other buffer upon
entering it.
------------------------------------------------------------------------------
:IndentGuidesDisable *:IndentGuidesDisable*
Disables the indent guides for the current buffer and any other buffer upon
entering it.
==============================================================================
3. OPTIONS *indent-guides-options*
------------------------------------------------------------------------------
*'indent_guides_indent_levels'*
Use this option to control how many indent levels to display guides for.
Default: 30. Values: integer.
>
let g:indent_guides_indent_levels = 30
<
------------------------------------------------------------------------------
*'indent_guides_auto_colors'*
Use this option to control whether or not the plugin automatically calculates
the highlight colors. Will use the current colorscheme's background color as a
base color.
Default: 1. Values: 0 or 1.
>
let g:indent_guides_auto_colors = 1
<
If you set this option to 0, be sure to manually define some highlight colors
in an autocmd.
>
let g:indent_guides_auto_colors = 0
autocmd VimEnter,Colorscheme * :hi IndentGuidesOdd guibg=red ctermbg=3
autocmd VimEnter,Colorscheme * :hi IndentGuidesEven guibg=green ctermbg=4
<
Alternatively you can add the following lines to your colorscheme file.
>
hi IndentGuidesOdd guibg=red ctermbg=3
hi IndentGuidesEven guibg=green ctermbg=4
<
------------------------------------------------------------------------------
*'indent_guides_color_change_percent'*
Use this option to control the percent at which the highlight colors will be
lightened or darkened.
Default: 10 (10%). Values: between 0 and 100.
>
let g:indent_guides_color_change_percent = 10
<
------------------------------------------------------------------------------
*'indent_guides_guide_size'*
Use this option to customize the size of the indent guide. By default the
value is set to 0, which will set the guide size to be the same as the
|shiftwidth|. Setting this value to be larger than the |shiftwidth| is essentially
the same as setting it to 0.
A common use of this setting is to create skinny indent guides, which look
great with a |shiftwidth| of 4 or more.
NOTE: This option only works for soft-tabs (spaces) and not hard-tabs.
Default: 0. Values: between 0 and |shiftwidth|.
>
let g:indent_guides_guide_size = 1
<
------------------------------------------------------------------------------
*'indent_guides_start_level'*
Use this option to control which indent level to start showing guides from.
Default: 1. Values: between 1 and g:|indent_guides_indent_levels|.
>
let g:indent_guides_start_level = 2
<
------------------------------------------------------------------------------
*'indent_guides_space_guides'*
Use this option to control whether the plugin considers spaces as indention.
Default: 1. Values: 0 or 1.
>
let g:indent_guides_space_guides = 0
<
------------------------------------------------------------------------------
*'indent_guides_tab_guides'*
Use this option to control whether the plugin considers tabs as indention.
Default: 1. Values: 0 or 1.
>
let g:indent_guides_tab_guides = 0
<
------------------------------------------------------------------------------
*'indent_guides_soft_pattern'*
Use this option to explicitly specify a pattern for soft indentation. For
example to match spaces only in the beginning of line use ' ' pattern.
Default: '\s'. Values: Vim regexp.
>
let g:indent_guides_soft_pattern = ' '
<
------------------------------------------------------------------------------
*'indent_guides_enable_on_vim_startup'*
Use this option to control whether the plugin is enabled on Vim startup.
Default: 0. Values: 0 or 1.
>
let g:indent_guides_enable_on_vim_startup = 0
<
------------------------------------------------------------------------------
*'indent_guides_exclude_filetypes'*
Use this option to specify a list of filetypes to disable the plugin for.
Default: ['help']. Values: list of strings.
>
let g:indent_guides_exclude_filetypes = ['help', 'nerdtree']
<
------------------------------------------------------------------------------
*'indent_guides_default_mapping'*
Use this option to control whether the default mapping (<Leader>ig) gets set.
Default: 1. Values: 0 or 1.
>
let g:indent_guides_default_mapping = 0
<
==============================================================================
4. MAPPINGS *indent-guides-mappings*
The default mapping for toggling indent guides is <Leader>ig. You can easily
map it to other keys. For example:
>
:nmap <silent> <Leader>ig <Plug>IndentGuidesToggle
<
You can also map some other commands that are not mapped by default. For
example:
>
:nmap <silent> <Leader>ie <Plug>IndentGuidesEnable
:nmap <silent> <Leader>id <Plug>IndentGuidesDisable
<
==============================================================================
5. TERMINAL VIM *indent-guides-terminal-vim*
At the moment Terminal Vim only has basic support. This means is that colors
won't be automatically calculated based on your colorscheme. Instead, some
preset colors are used depending on whether `background` is set to `dark` or
`light`.
When `set background=dark` is used, the following highlight colors will be
defined:
>
hi IndentGuidesOdd ctermbg=black
hi IndentGuidesEven ctermbg=darkgrey
<
Alternatively, when `set background=light` is used, the following highlight
colors will be defined:
>
hi IndentGuidesOdd ctermbg=white
hi IndentGuidesEven ctermbg=lightgrey
<
If for some reason it's incorrectly defining light highlight colors instead of
dark ones or vice versa, the first thing you should check is that the
`background` value is being set correctly for your colorscheme. Sometimes it's
best to manually set the `background` value in your `.vimrc`, for example:
>
colorscheme desert256
set background=dark
<
Alternatively you can manually setup the highlight colors yourself, see
|indent_guides_auto_colors| for an example.

6. ABOUT *indent-guides-about*
Why did I build this plugin?~
* I believe indent guides make nested code easier to read and understand.
* Other editors have them and it's high time Vim did.
* None of the existing indent guide plugins on the market suited my needs.
* I wanted to learn me some VimL.

hex codes from his CSApprox plugin.
