Error from fts/common.lua attempt to index python

[MikeLemo1]

I've basically installed iron on ubuntu 24.04 the latest nvim with lazy in bash with the following slightly edited config:

 local M = {
  'Vigemus/iron.nvim'
}

function M.config()
  local iron = require("iron.core")

  iron.setup {
    config = {
      -- Whether a repl should be discarded or not
      scratch_repl = true,
      -- Your repl definitions come here
      repl_definition = {
        sh = {
          -- Can be a table or a function that
          -- returns a table (see below)
          command = {"bash"}
        }
      },
      -- How the repl window will be displayed
      -- See below for more information
      repl_open_cmd = require('iron.view').bottom(40),
    },
    -- Iron doesn't set keymaps by default anymore.
    -- You can set them here or manually add keymaps to the functions in iron.core
    keymaps = {
      send_motion = "<space>sc",
      visual_send = "<space>sc",
      send_file = "<space>ef",
      send_line = "<space>el",
      send_paragraph = "<space>sp",
      send_until_cursor = "<space>su",
      send_mark = "<space>sm",
      mark_motion = "<space>mc",
      mark_visual = "<space>mc",
      remove_mark = "<space>md",
      cr = "<space>s<cr>",
      interrupt = "<space>s<space>",
      exit = "<space>sq",
      clear = "<space>cl",
    },
    -- If the highlight is on, you can change how it looks
    -- For the available options, check nvim_set_hl
    highlight = {
      italic = true
    },
    ignore_blank_lines = true, -- ignore blank lines when sending visual select lines
  }

  -- iron also has a list of commands, see :h iron-commands for all available commands
  vim.keymap.set('n', '<space>rs', '<cmd>IronRepl<cr>')
  vim.keymap.set('n', '<space>rr', '<cmd>IronRestart<cr>')
  vim.keymap.set('n', '<space>rf', '<cmd>IronFocus<cr>')
  vim.keymap.set('n', '<space>rh', '<cmd>IronHide<cr>')

end

doing send_file sends the following error:

E5108: Error executing lua: ....local/share/nvim/lazy/iron.nvim/lua/iron/fts/common.lua:99: attempt to in
dex field 'python' (a nil value)
stack traceback:

Any idea?

Also I'm not sure how to run the whole file, one line, visual selection with lua functions

@MikeLemo1 I am not associated to dev-team but here is a fix if you are in Linux:
Find the common.lua file inside of the package and set local is_python = false in line 93.
For the dev team (@nickeisenberg ) : there seems to be some nasty circular dependency: "common-> config -> init->python->common" Id be interested to write a PR if you guys'd like.

@MikeLemo1 @ottersome Hey sorry for the late reply. There is a bug here that I noticed awhile back. I have been busy and was not able to get to it. The problem is that if repl_definition is not nil then you need to specify the setup for each language.

@ottersome feel free to submit a PR! That would be highly appreciated and I can look at it this weekend.

@MikeLemo1 a quick fix for this right now would be to do either of the following in your configuration:

1. repl_definition = nil

    local python_format = require("iron.fts.common").bracketed_paste_python
    local repl_definition = {
      python = {
        command = { "python3" },
        format = python_format
      }
    }

    iron.setup {
      config = {
        ...,
        repl_definition = repl_definition
        ..., 
      },
      ...,
    }
