satellite.nvim

satellite.nvim is a Neovim plugin that displays decorated scrollbars.

NOTE: Many API's required to implement a decorated scrollbar in Neovim do not yet exist, and because of this, this plugin implements fairly unideal and unoptimised workarounds to get desired behaviours.

Features

Display marks for different kinds of decorations across the buffer. Builtin handlers include:
- Cursor
- Search results
- Diagnostic
- Git hunks (via gitsigns.nvim)
- Marks
- Quickfix
Handling for folds
Mouse support

Requirements

Neovim nightly

Usage

Enabled by default. Configuration can optionally be passed to the setup() function. Here is an example with most of the default settings:

require('satellite').setup {
  current_only = false,
  winblend = 50,
  zindex = 40,
  excluded_filetypes = {},
  width = 2,
  handlers = {
    cursor = {
      enable = true,
      -- Supports any number of symbols
      symbols = { '⎺', '⎻', '⎼', '⎽' }
      -- symbols = { '⎻', '⎼' }
      -- Highlights:
      -- - SatelliteCursor (default links to NonText
    },
    search = {
      enable = true,
      -- Highlights:
      -- - SatelliteSearch (default links to Search)
      -- - SatelliteSearchCurrent (default links to SearchCurrent)
    },
    diagnostic = {
      enable = true,
      signs = {'-', '=', '≡'},
      min_severity = vim.diagnostic.severity.HINT,
      -- Highlights:
      -- - SatelliteDiagnosticError (default links to DiagnosticError)
      -- - SatelliteDiagnosticWarn (default links to DiagnosticWarn)
      -- - SatelliteDiagnosticInfo (default links to DiagnosticInfo)
      -- - SatelliteDiagnosticHint (default links to DiagnosticHint)
    },
    gitsigns = {
      enable = true,
      signs = { -- can only be a single character (multibyte is okay)
        add = "│",
        change = "│",
        delete = "-",
      },
      -- Highlights:
      -- SatelliteGitSignsAdd (default links to GitSignsAdd)
      -- SatelliteGitSignsChange (default links to GitSignsChange)
      -- SatelliteGitSignsDelete (default links to GitSignsDelete)
    },
    marks = {
      enable = true,
      show_builtins = false, -- shows the builtin marks like [ ] < >
      key = 'm'
      -- Highlights:
      -- SatelliteMark (default links to Normal)
    },
    quickfix = {
      signs = { '-', '=', '≡' },
      -- Highlights:
      -- SatelliteQuickfix (default links to WarningMsg)
    }
  },
}

The :SatelliteDisable command disables scrollbars.
The :SatelliteEnable command enables scrollbars. This is only necessary if scrollbars have previously been disabled.
The :SatelliteRefresh command refreshes the scrollbars. This is relevant when the scrollbars are out-of-sync, which can occur as a result of some window arrangement actions.

Configuration

There are various settings that can be configured. Please see the documentation for details.

Handlers

Satellite provides an API to implement handlers for the scrollbar, see HANDLERS for more details.

Credit

This plugin was based on nvim-scrollview which provides a very good implementation for a normal scrollbar.
