Need help with statusline.

[dharmx]

I was trying to integrate this to my custom statusline and at first it was working perfectly fine:

local M = {}

local config = require("statusline.config").treesitter

function M.treesitter()
  local format = "%#Statusline#"
  if _G.packer_plugins and _G.packer_plugins["nvim-gps"].loaded then
    local scopes = require "nvim-gps"
    local fallback = string.format(
      "%%#StatusLineScopesOFF#%s%%#StatusLineScopes#%%#StatusLineScopesReverse#%s%%#Statusline#",
      config.disabled_icon,
      config.style.left
    )

    local location = string.format(
      "%%#StatusLineScopesON#%s%%#StatusLineScopes#%s%%#StatusLineScopesReverse#%s%%#Statusline#",
      config.enabled_icon,
      scopes.get_location(),
      config.style.left
    )

    format = scopes.is_available() and location or fallback
  end

  return format
end

return M

But the problem with the above snippet is that it throws error for filetypes that do not have a treesitter parser.

E5108: Error executing lua ...nvim/site/pack/packer/opt/nvim-gps/lua/nvim-gps/init.lua:358: bad argument #1 to 'pairs' (table expected, got string)
stack traceback:
        [C]: in function 'pairs'
        ...nvim/site/pack/packer/opt/nvim-gps/lua/nvim-gps/init.lua:358: in function 'get_location'
        ...maker/.config/nvim/lua/statusline/modules/treesitter.lua:25: in function 'treesitter'
        /home/maker/.config/nvim/lua/statusline/init.lua:29: in function </home/maker/.config/nvim/lua/statusline/init.lua:20>

I used a workaround to get through this by the way:

local parser_location = stdpath "data" .. string.format("/site/pack/packer/opt/nvim-treesitter/parser/%s.so", bo.filetype)
if not exists(parser_location) then return format end

Now everything was fine for a solid 3 days, until I opened a markdown file. Now, it again threw that same error. So, I verified if a parser was installed, and it was. To workaround this I excluded mardown completely.

StatusLine = function(state)
  set_colors(api.nvim_get_mode().mode)
  local combined = "%#StatusLineInactive#%=" .. modules.filename(true) .. "%="
  if state == "active" then
    local ok, ts = pcall(modules.treesitter)
    local left = table.concat {
      modules.mode(),
      modules.dirname(),
      modules.filename(),
      ok and ts or "%#Statusline#",
    }
    local right = table.concat {
      "%=",
      modules.diagnostics(),
      modules.lsp(),
      modules.git(),
      modules.position(),
    }
    combined = left .. right
  elseif state == "inactive" then
    combined = "%#StatuslineNC#"
  end
  return combined
end

I am not really sure if this is a bug or, not so, I would love to have some insight! Maybe a treesitter API utility function that looks if the parser supports X or, not(?)

I haven't looked at the config closely, but this error

E5108: Error executing lua ...nvim/site/pack/packer/opt/nvim-gps/lua/nvim-gps/init.lua:358: bad argument #1 to 'pairs' (table expected, got string)
stack traceback:

will occur only when the get_location function is called when is_available is false.

[SmiteshP]

But the problem with the above snippet is that it throws error for filetypes that do not have a treesitter parser.

You could try replacing the call to get_location with a custom function like this

local functionl my_gps()
    if gps.is_available() then
        return gps.get_location()
    else
        return ""
    end
end

This is so embarassing! I wish I could delete this issue!!! This is the code now... so much shorter.

function M.treesitter()
  local fallback = "%%#StatusLineScopesOFF#%s%%#StatusLineScopes#%%#StatusLineScopesReverse#%s%%#Statusline#"
  local available = "%%#StatusLineScopesON#%s%%#StatusLineScopes#%s%%#StatusLineScopesReverse#%s%%#Statusline#"
  if packer_plugins and packer_plugins["nvim-gps"].loaded then
    local scopes = require "nvim-gps"
    return scopes.is_available()
        and string.format(available, config.enabled_icon, scopes.get_location(), config.style.left)
      or string.format(fallback, config.disabled_icon, config.style.left)
  end
  return "%#Statusline#"
end

Thanks for the quick response by the way! Closing...

Haha no worries 😄
