Expected lua string

[KeqiZeng]

HI! At first, thanks a lot for the nice plugin.

When I used this plugin just now, I got an error:

E5108: Error executing lua ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:89: Expected lua string
stack traceback:
        [C]: in function 'cmd'
        ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:89: in function 'run_filetype'
        ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:138: in function 'run_code'
        [string ":lua"]:1: in main chunk

here is my minimal init.lua about code_runner:

use { 'CRAG666/code_runner.nvim', requires = 'nvim-lua/plenary.nvim' }   in packer

require('code_runner').setup {
  term = {
    position = "belowright",
    size = 8
  },
  filetype_path = "$HOME/.config/nvim/code_runner.json",
  project_path = "$HOME/.config/nvim/projects.json"
}

and here is my coder_runner.json:

{
      "python": "python -u"
}

It seems also like this for other languages.

I'm getting the same issue and still happens after the latest fix. The only way to fix the issue is to add vim.g.fileCommands = {python = 'python3'} to my init.lua.

Now I get this error:

E5108: Error executing lua ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:43: attempt to index field 'fileC
ommands' (a nil value)
stack traceback:

        ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:81: in function 'run_filetype'
        ...cker/start/code_runner.nvim/lua/code_runner/commands.lua:138: in function 'run_code'
        [string ":lua"]:1: in main chunk

I also try to addvim.g.fileCommands = {python = 'python3'}(as @KarimLeVallois said) to my init.lua, but there is nothing different on my laptop.

I find this issue is same as #14. I try to configure in pure lua as you recommended, and it works fine for a single file. So I think this plugin maybe can not correctly recognize my json flie? What should I do if i want to configure with json? Thank you so much for your effort!!

[CRAG666]

This is my personal configuration, yes use json file

require('code_runner').setup({
  term = {
    size = 15,
  },
  filetype_path = vim.fn.expand('~/.config/nvim/code_runner.json'),
  project_path = vim.fn.expand('~/.config/nvim/project_manager.json'),
}

{
    "javascript": "node",
    "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",
    "kotlin": "cd $dir && kotlinc-native $fileName -o $fileNameWithoutExt && ./$fileNameWithoutExt.kexe",
    "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt && $dir/$fileNameWithoutExt",
    "cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir/$fileNameWithoutExt",
    "python": "python -u",
    "shellscript": "bash",
    "csharp": "cd $dir && mcs $fileName && mono $fileNameWithoutExt.exe",
    "typescript": "deno run",
    "rust": "cd $dir && rustc $fileName && $dir$fileNameWithoutExt",
    "dart": "dart"
}

[CRAG666]

This is a setup using pure lua:

require('code_runner').setup {
  term = {
    size = 15,
  },
  filetype = {
    java = "cd $dir && javac $fileName && java $fileNameWithoutExt",
    python = "python -u",
    typescript = "deno run",
    rust = "cd $dir && rustc $fileName && $dir/$fileNameWithoutExt"
  },
}

The error existed before the last commit, try to update the plugin and check if the problem persists, because of all the tests that I have done, the plugin works without any problem. Remember that if it is json, you should not include trailing commas, that is, a comma after the last element. In case you use lua also try to write a correct table format because all these things the plugin cannot or should not handle. Finally, if this is resolved, I would appreciate closing the issue or, if applicable, doing a pr.

try to expand the url, above leave how you do it in vim, remember that code runner works with absolute not relative paths, in fact I will be more clear, I will add more explanation of this in the README

[CRAG666]

Thank you for letting me know that the projects weren't working, data that failed because I called them projects and not project. It was so simple to correct but here I leave the complete example configuration:

require('code_runner').setup {
  term = {
    size = 15,
  },
  filetype = {
    java = "cd $dir && javac $fileName && java $fileNameWithoutExt",
    python = "python -u",
    typescript = "deno run",
    rust = "cd $dir && rustc $fileName && $dir/$fileNameWithoutExt"
  },
  project = {
    ["~/prueba"] = {
      name = "App1",
      description = "Tmx frontend api",
      file_name = "prueba.py"
    },
  }
}

Sorry for being late in replying. Now it works totally fine. I think my issue comes from here:

At first I just copy the config example to my init.lua, but it can't work so good.

Just now I change

filetype_path = "$HOME/.config/nvim/code_runner.json",
project_path = "$HOME/.config/nvim/projects.json"

to

filetype_path = vim.fn.expand('~/.config/nvim/code_runner.json'),
project_path = vim.fn.expand('~/.config/nvim/project_manager.json'),

Then it can works fine. Whatever, thank you so much again for your explanation.
