Configuration

(Default values are shown below)

require'treesitter-context'.setup{
  enable = true, -- Enable this plugin (Can be enabled/disabled later via commands)
  max_lines = 0, -- How many lines the window should span. Values <= 0 mean no limit.
  min_window_height = 0, -- Minimum editor window height to enable context. Values <= 0 mean no limit.
  line_numbers = true,
  multiline_threshold = 20, -- Maximum number of lines to collapse for a single context line
  trim_scope = 'outer', -- Which context lines to discard if `max_lines` is exceeded. Choices: 'inner', 'outer'
  mode = 'cursor',  -- Line used to calculate context. Choices: 'cursor', 'topline'
  -- Separator between context and content. Should be a single character string, like '-'.
  -- When separator is set, the context will only show up when there are at least 2 lines above cursorline.
  separator = nil,
  zindex = 20, -- The Z-index of the context window
  on_attach = nil, -- (fun(buf: integer): boolean) return false to disable attaching
}

Commands

TSContextEnable, TSContextDisable and TSContextToggle.

Appearance

Use the highlight group TreesitterContext to change the colors of the context. Per default it links to NormalFloat.

Use the highlight group TreesitterContextLineNumber to change the colors of the context line numbers if line_numbers is set. Per default it links to LineNr.

Use the highlight group TreesitterContextBottom to change the highlight of the last line of the context window. By default it links to NONE. However, you can use this to create a border by applying an underline highlight, e.g:

hi TreesitterContextBottom gui=underline guisp=Grey

Jumping to context (upwards)

vim.keymap.set("n", "[c", function()
  require("treesitter-context").go_to_context()
end, { silent = true })
