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.
|
||
|
|
|
||

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
|
||
|
|
<
|

|
|
|
||
|
|
------------------------------------------------------------------------------
|

|

>

|
|
------------------------------------------------------------------------------
|
||
|

|
||
|
|
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.
|
||
|
|
>
|

|
||
|
|
>

|
||
|
|
<
|
||
|
|
|
||
|
|
==============================================================================
|
||
|
|
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.
