Harpoon Setup

[amalavet]

Just thought if anyone wanted to have pinned buffers map to harpoon, this would be helpful

return {
    "romgrk/barbar.nvim",
    dependencies = { "ThePrimeagen/harpoon" },
    config = function()
        local barbar = require("barbar")
        local state = require("barbar.state")
        local render = require("barbar.ui.render")
        local harpoon = require("harpoon")

        barbar.setup({
            hide = {
                inactive = true,
            },
            icons = {
                pinned = { filename = true, buffer_index = true },
                diagnostics = { { enabled = true } },
            },
        })

        local function unpin_all()
            for _, buf in ipairs(state.buffers) do
                local data = state.get_buffer_data(buf)
                data.pinned = false
            end
        end

        local function get_buffer_by_mark(mark)
            for _, buf in ipairs(vim.api.nvim_list_bufs()) do
                local buffer_path = vim.api.nvim_buf_get_name(buf)

                if buffer_path == "" or mark.value == "" then
                    goto continue
                end

                local mark_pattern = mark.value:gsub("([%(%)%.%%%+%-%*%?%[%]%^%$])", "%%%1")
                if string.match(buffer_path, mark_pattern) then
                    return buf
                end

                local buffer_path_pattern = buffer_path:gsub("([%(%)%.%%%+%-%*%?%[%]%^%$])", "%%%1")
                if string.match(mark.value, buffer_path_pattern) then
                    return buf
                end

                ::continue::
            end
        end

        local function refresh_all_harpoon_tabs()
            local list = harpoon:list()
            unpin_all()
            for _, mark in ipairs(list.items) do
                local buf = get_buffer_by_mark(mark)
                if buf == nil then
                    vim.cmd("badd " .. mark.value)
                    buf = get_buffer_by_mark(mark)
                end
                if buf ~= nil then
                    state.toggle_pin(buf)
                end
            end
            render.update()
        end

        vim.api.nvim_create_autocmd({ "BufEnter", "BufAdd", "BufLeave", "User" }, {
            callback = refresh_all_harpoon_tabs,
        })
    end,
}

One other note, I have my harpoon add call the "User" autocmd to update the tabs

        vim.keymap.set("n", "<leader>pa", function()
            harpoon:list():add()
            vim.cmd(":do User")
        end, { desc = "Harpoon: Add file" })
