A code minimap for Vim

The Sublime text-editor can display an useful overview of the code as a minimap sidebar.

We can implement the same thing in Vim, relying on the Drawille library to 'draw' in text mode.

minimap in action

This code is made available under a MIT license. See LICENSE for details.

Features

  • displays the minimap of the currently active buffer (and updates when switching to a different buffer)
  • synchronized scrolling
  • live update while typing

Installation

Note that this extension requires Vim with Python support.

Vundle

With vundle, simply add: Plugin 'severin-lemaignan/vim-minimap' to your .vimrc and run :PluginInstall from vim.

Janus

With Janus just clone inside .janus.

cd ~/.janus
git clone https://github.com/severin-lemaignan/vim-minimap.git vim-minimap

AUR

AUR just has vim-minimap-git package.

Usage

:Minimap to show the minimap, :MinimapClose to hide it.

Default mappings: <Leader>mm to display the minimap, <Leader>mc to close it.

To overwrite the default keybindings, using following settings in ``.vimrc'':

let g:minimap_show='<leader>ms'
let g:minimap_update='<leader>mu'
let g:minimap_close='<leader>gc'
let g:minimap_toggle='<leader>gt'

Settings

You can customize the color of the highlighting by setting g:minimap_highlight in your vimrc:

let g:minimap_highlight='Visual'

Note: To find out which highlights are available on your vim installation use :hi to get the list.

Troubleshooting

Weird display

Problem:

Certain fonts do not display plain dots and empty spaces, but plain dots and circles for braille characters.

For example, with Inconsolata:

Solution:

As a result, you may want to use any other font that display braille characters in a way that suit the minimap plugin, like Ubuntu Mono, or Droid Sans Mono.

With Ubuntu Mono:
