@Betelgeuse1 Thanks for sharing this code snippet, I was just trying to do the same thing.

For those who would also like to get GitChange highlight, you can rely on the non public function of gitsign require('gitsigns.hunks').calc_signs

View Code

local gitsign = require('gitsigns')
local gitsign_hunks = require('gitsigns.hunks')

require('scrollbar.handlers').register('git', function(bufnr)
    local nb_lines = vim.api.nvim_buf_line_count(bufnr)
    -- NOTE: change to corresponding marks from scrollbar setup 
    local colors_type = {
        add = 'GitAdd',
        delete = 'GitDelete',
        change = 'GitChange',
        changedelete = 'GitChange'
    }

    local lines = {}
    local hunks = gitsign.get_hunks(bufnr)
    if hunks then
        for _, hunk in ipairs(hunks) do
            hunk.vend = math.min(hunk.added.start, hunk.removed.start) + hunk.added.count + hunk.removed.count
            local signs = gitsign_hunks.calc_signs(hunk, 0, nb_lines)
            for _, sign in ipairs(signs) do
                table.insert(lines, {
                    line = sign.lnum,
                    type = colors_type[sign.type]
                })
            end
        end
    end
    return lines
end)

Don't know if it's pertinent but I started working on an handler for that purpose, got this far.

-- new marks
GitAdd = {
  text = { "█" },
  priority = 5,
  color = palette.blue[1],
  cterm = nil,
  highlight = "CursorColumn",
},
GitDel = {
  text = { "█" },
  priority = 5,
  color = palette.red[1],
  cterm = nil,
  highlight = "CursorColumn",
},
GitChg = {
  text = { "█" },
  priority = 5,
  color = palette.orange[1],
  cterm = nil,
  highlight = "CursorColumn",
},

-- custom handler -- not working right now
require('scrollbar.handlers').register('git', function()
  local hunks = require('gitsigns').get_hunks()
  local lines = {}

  if hunks == nil then
    return lines
  end

  for _, hunk in pairs(hunks) do
    for i = 1, #hunk.added, 1 do
      table.insert(lines, {
        line = hunk.added[i].start + (i - 2),
        type = "GitAdd",
      })
    end
    for i = 1, #hunk.removed, 1 do
      table.insert(lines, {
        line = hunk.removed[i].start + (i - 2),
        type = "GitDel",
      })
    end
  end

  return lines
end)
