Setup

require("scrollbar").setup()

![search](./assets/search.gif) #### Setup (Packer) ```lua use { "kevinhwang91/nvim-hlslens", config = function() -- require('hlslens').setup() is not required require("scrollbar.handlers.search").setup({ -- hlslens config overrides }) end, } ``` OR ```lua use { "kevinhwang91/nvim-hlslens", config = function() require("hlslens").setup({ build_position_cb = function(plist, _, _, _) require("scrollbar.handlers.search").handler.show(plist.start_pos) end, }) vim.cmd([[ augroup scrollbar_search_hide autocmd! autocmd CmdlineLeave : lua require('scrollbar.handlers.search').handler.hide() augroup END ]]) end, } ``` If you want to leave only search marks and disable virtual text: ```lua require("scrollbar.handlers.search").setup({ override_lens = function() end, }) ```

Config

Defaults

```lua require("scrollbar").setup({ show = true, show_in_active_only = false, set_highlights = true, folds = 1000, -- handle folds, set to number to disable folds if no. of lines in buffer exceeds this max_lines = false, -- disables if no. of lines in buffer exceeds this hide_if_all_visible = false, -- Hides everything if all lines are visible throttle_ms = 100, handle = { text = " ", blend = 30, -- Integer between 0 and 100. 0 for fully opaque and 100 to full transparent. Defaults to 30. color = nil, color_nr = nil, -- cterm highlight = "CursorColumn", hide_if_all_visible = true, -- Hides handle if all lines are visible }, marks = { Cursor = { text = "•", priority = 0, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "Normal", }, Search = { text = { "-", "=" }, priority = 1, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "Search", }, Error = { text = { "-", "=" }, priority = 2, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "DiagnosticVirtualTextError", }, Warn = { text = { "-", "=" }, priority = 3, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "DiagnosticVirtualTextWarn", }, Info = { text = { "-", "=" }, priority = 4, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "DiagnosticVirtualTextInfo", }, Hint = { text = { "-", "=" }, priority = 5, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "DiagnosticVirtualTextHint", }, Misc = { text = { "-", "=" }, priority = 6, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "Normal", }, GitAdd = { text = "┆", priority = 7, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "GitSignsAdd", }, GitChange = { text = "┆", priority = 7, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "GitSignsChange", }, GitDelete = { text = "▁", priority = 7, gui = nil, color = nil, cterm = nil, color_nr = nil, -- cterm highlight = "GitSignsDelete", }, }, excluded_buftypes = { "terminal", }, excluded_filetypes = { "cmp_docs", "cmp_menu", "noice", "prompt", "TelescopePrompt", }, autocmd = { render = { "BufWinEnter", "TabEnter", "TermEnter", "WinEnter", "CmdwinLeave", "TextChanged", "VimResized", "WinScrolled", }, clear = { "BufWinLeave", "TabLeave", "TermLeave", "WinLeave", }, }, handlers = { cursor = true, diagnostic = true, gitsigns = false, -- Requires gitsigns handle = true, search = false, -- Requires hlslens ale = false, -- Requires ALE }, }) ```

Colors/Highlights

Color takes precedence over highlight i.e. if color is defined, that will be used to define the highlight instead of highlight.

Mark type highlights are in the format of Scrollbar<MarkType> and Scrollbar<MarkType>Handle. If you wish to define these yourself, add set_highlights = false to the setup.

Example config with tokyonight.nvim colors

local colors = require("tokyonight.colors").setup()

require("scrollbar").setup({
    handle = {
        color = colors.bg_highlight,
    },
    marks = {
        Search = { color = colors.orange },
        Error = { color = colors.error },
        Warn = { color = colors.warning },
        Info = { color = colors.info },
        Hint = { color = colors.hint },
        Misc = { color = colors.purple },
    }
})

Custom Handlers

One can define custom handlers consisting of a name and a lua function that returns a list of marks as follows:

require("scrollbar.handlers").register(name, handler_function)

handler_function receives the buffer number as argument and must return a list of tables with line, text, type, and level keys. Only the line key is required.

Key	Description
`line`	The line number. Required.
`text`	Marker text. Defaults to global settings depending on `type`.
`type`	The marker type. Default is `Misc`.
`level`	Marker level. Default is `1`.

E.g. the following marks the first three lines in every buffer.

require("scrollbar.handlers").register("my_marks", function(bufnr)
    return {
        { line = 0 },
        { line = 1, text = "x", type = "Warn" },
        { line = 2, type = "Error" }
    }
end)
