📡 minimap.vim

Blazing fast minimap for vim, powered by 🛰 code-minimap written in Rust.

✨ Features

• Blazing-fast (see benchmark).
• Dynamic scaling.
• Real-time highlight.
• It can be used to scroll buffer (in vim's way!).

📥 Installation

Requirement

• 🛰code-minimap is required. The plugin receives rendered minimap from it.
• vim8.2+, or neovim 0.5.0+.

Use your favorite plugin manager, vim-plug for example:

Plug 'wfxr/minimap.vim'

If you need to install the plugin manually, you can refer to this issue: #2.

You can use cargo to install 'code-minimap' simultaneously (Only recommended for rust users):

Plug 'wfxr/minimap.vim', {'do': ':!cargo install --locked code-minimap'}

📑 Example configuration

let g:minimap_width = 10
let g:minimap_auto_start = 1
let g:minimap_auto_start_win_enter = 1

🛠 Commands

⚙ Options

⚙ Color Options

Minimap.vim sets its own color groups to give a reasonable default.

You can create your own colorgroup by specifying the foreground and background colors for the cterm or gui:

:highlight minimapCursor ctermbg=59  ctermfg=228 guibg=#5F5F5F guifg=#FFFF87

For more information, see :help highlight

Note: some colorschemes will clear all previous colors, so you may have to add an autocmd to ensure your custom colorgroups are added back:

autocmd ColorScheme *
        \ highlight minimapCursor            ctermbg=59  ctermfg=228 guibg=#5F5F5F guifg=#FFFF87 |
        \ highlight minimapRange             ctermbg=242 ctermfg=228 guibg=#4F4F4F guifg=#FFFF87

If you prefer to disable this behavior, set g:minimap_enable_highlight_colorgroup to 0 / false. This is useful if you have a color scheme that sets the minimap highlight groups explicitly.

💬 F.A.Q

---

Highlight and scroll are not working properly.

Check the vim version you are using. minimap.vim requires vim 8.2+ or neovim 0.5.0+.

---

Integrated with diagnostics or git status plugins?

Git integration is supported. See g:minimap_git_colors and #72.

---

Minimap window is too wide for me, how to use it as a simple scrollbar?

You can reduce the width of the minimap window:

let g:minimap_width = 2

Or use scrollbar.nvim instead if what you want is a pure scrollbar indicator.

---

How do the color priorities work?

A higher priority color group will override a lower priority color group. By default, search > cursor/window position > git colors

---

I don't like the default highlight group, how to change it?

Choose any one of the highlight groups (or define a new one) and just set it for minimap like this:

hi MinimapCurrentLine ctermfg=Green guifg=#50FA7B guibg=#32302f
let g:minimap_cursor_color = 'MinimapCurrentLine'

All existing highlight groups can be displayed by :hi.

---

Minimap shows up as a jumble of characters?

Check that your encoding is set to utf-8 and not latin1 (for Vim users). Also, ensure that you're using a Unicode-compatible font that has Braille characters in it.

---

What is g:minimap_highlight_range and how do you use it?

You can have the minimap highlight all the visible lines in your current window by setting g:minimap_highlight_range. If you use Neovim, and your version is recent enough (after November 7, 2020), you can set this option to update the highlight when the window is scrolled.

---

I'm using g:minimap_highlight_search and the highlighted searches don't go away until I :nohlsearch and save!

It is recommended that you create a mapping to run :nohlsearch and clear the minimap all in one action. For example:

nnoremap <silent> `` :nohlsearch<CR>:call minimap#vim#ClearColorSearch()<CR>

---

I'm using g:minimap_background_processing on MacOS and the minimap isn't working!

The version of wc that ships with MacOS does not have support for the -L flag. To use background processing on MacOS, install gnu-wc. Example via homebrew:

brew install coreutils

📋 Running Unit Tests

• Install Testify.
• From the top level directory (minimap.vim/) vim +TestifySuite for a yay/nay from your shell.
• For a more detailed run, open vim at the top level and run :TestifySuite. README.md works, but an empty buffer at the top level works too.
• To hone in on one test file, open that file (located in the t/ directory) and run :TestifyFile.
  • (As a note, the t/ directory is named such as a requirement from Testify. :TestifySuite runs all the tests in the t/ directory)
