mistfly statusline

mistfly statusline is a simple, fast and informative statusline for Vim.

:point_right: Neovim users should use the pure-Lua linefly plugin instead of mistfly.

mistfly provides a number of useful builtin components:

• Git changes
• Diagnostic status
• Macro-recording status
• Current search count
• Spell status
• Indent status (tabs or spaces and their associated width)

mistfly also provides optional tabline support when the appropriate setting is enabled; refer to mistflyTabLine.

mistfly will adapt it's colors to the colorscheme currently in effect. Colors can also be customized if desired.

Lastly, mistfly is a lean statusline plugin clocking in at about 500 lines of code. For comparison, the lightline, airline and lualine statusline plugins contain over 3,600, 7,300 and 8,200 lines of code respectively. In fairness, the latter plugins are more featureful, configurable and visually pleasing.

:warning: mistfly has a predominantly fixed layout, this will not be an appropriate statusline plugin if layout flexibility is desired.

Screenshots

The above screenshots are using the nightfly colorscheme and the Iosevka font with Git changes, diagnostics and indent-status enabled.

Statusline Startup Comparison

A startup comparison of mistfly against various popular statusline plugins, with their out-of-the-box defaults, on a clean and minimal Vim setup with the moonfly colorscheme. The Vim startup times in the following table are provived by the dstein64/vim-startuptime plugin.

Startup times are the average of five consecutive runs. Note, stock is run without any statusline plugin.

Startup times as of March 2024 on my system; performance on other systems will vary.

Plugins, Linters and Diagnostics supported

• vim-devicons and nvim-web-devicons

• Gitsigns

• GitGutter

• Signify

• ALE

• Coc

• Obsession

:zap: Requirements

mistfly requires Vim 8 (or later), Neovim is not supported. The pure-Lua linefly plugin should instead be used with Neovim.

Please also make sure that the laststatus option is set to either: 1, 2 or 3.

Installation

Install bluz71/vim-mistfly-statusline with your preferred plugin manager.

vim-plug:

Plug 'bluz71/vim-mistfly-statusline'

lazy.nvim:

{ 'bluz71/vim-mistfly-statusline' },

Please do not lazy-load mistfly.

Layout And Default Colors

The mistfly-statusline layout consists of three groupings, the left-side, middle and right-side as follows:

+-------------------------------------------------+
| A | B | C | D          M          W | X | Y | Z |
+-------------------------------------------------+

Sections marked with a * are linked to a highlight group and are colored, refer to the next section for details.

Sections C, D & W will not be displayed when the statusline width is less than 80 columns.

Note, filenames will be displayed as follows:

• Pathless filenames only for files in the current working directory

• Relative paths in preference to absolute paths for files not in the current working directory

• ~-style home directory paths in preference to absolute paths

• Possibly shortened, for example foo/bar/bazz/hello.txt will be displayed as f/b/b/hello.txt when statusline width is less than 120 columns.

• Possibly trimmed. A maximum of four path components will be displayed for a filename; if a filename is more deeply nested then only the four most significant components, including the filename, will be displayed with an ellipsis prefix symbol used to indicate path trimming.

Highlight Groups And Colors

Sections marked with * in the previous section are linked to the following custom highlight groups with their associated fallbacks if the current colorscheme does not support mistfly.

Note, the following colorschemes support mistfly, either within the colorscheme (moonfly & nightfly) or within this plugin (all others):

• moonfly

• nightfly

• dracula

• edge

• embark

• everforest

• gruvbox

• gruvbox-material

• retrobox

• sonokai

Lastly, if the fallback colors do not suit then it is very easy to override with your own highlights.

:gift: Here is a simple example of customized mistfly colors. Save the following at the end of your initialization file after setting your colorscheme.

highlight! link MistflyNormal DiffChange
highlight! link MistflyInsert WildMenu
highlight! link MistflyVisual IncSearch
highlight! link MistflyCommand WildMenu
highlight! link MistflyReplace ErrorMsg
