LazyGit Statusline Override

lazygit-statusline.lua

--============================================================================--
--
-- Lazygit Editor Detection and Statusline Customization
--
--============================================================================--
--
-- This plugin detects when Neovim is launched from lazygit as an editor and
-- changes the statusline color to indicate this special editing mode. This helps
-- prevent confusion when editing files from within lazygit, as the editor
-- appears fullscreen and can be mistaken for a regular Neovim session.
--
-- To use this, configure lazygit to launch nvim with a flag:
-- os:
--   edit: 'nvim --cmd "let g:lazygit_editing=1" {{filename}}'
--   editAtLine: 'nvim --cmd "let g:lazygit_editing=1" +{{line}} {{filename}}'
--   editAtLineAndWait: 'nvim --cmd "let g:lazygit_editing=1" +{{line}} {{filename}}'
--   editInTerminal: true
--
-- On macOS the lazygit configuration lives here, by default: /Users/jon/Library/Application Support/lazygit/config.yml
