Code_Runner



🔥 Code Runner for Neovim written in pure lua 🔥






## Introduction



When I was still in college it was common to try multiple programming languages, at that time I used vscode that with a single plugin allowed me to run many programming languages, I left the ballast that are electron apps and switched to neovim, I searched the Internet and finally i found a lot of plugins, but none of them i liked (maybe i didn't search well), so i started adding autocmds like i don't have a tomorrow, this worked fine but this is lazy (maybe it will work for you, if you only programs in one or three languages maximum). So I decided to make this plugin and since the migration of my commands was very fast, it was just copy and paste and everything worked. Currently I don't test many languages anymore and work in the professional environment, but this plugin is still my swiss army knife.



## Requirements



- Neovim (>= 0.8)



## Install



- With [lazy.nvim](https://github.com/folke/lazy.nvim)



```lua

require("lazy").setup({

  { "CRAG666/code_runner.nvim", config = true },

}

```



- With [packer.nvim](https://github.com/wbthomason/packer.nvim)



```lua

use 'CRAG666/code_runner.nvim'

```



- With [paq-nvim](https://github.com/savq/paq-nvim)



```lua

require "paq"{ 'CRAG666/code_runner.nvim'; }

```



Please see my config [code_runner.lua](https://github.com/CRAG666/dotfiles/blob/main/config/nvim/lua/plugins/dev/code_runner.lua)



## Features



> **Note**

> If you want implement a new feature open an issue to know if it is worth implementing it and if there are people interested.



- Toggle runner(you need [CRAG666/betterTerm.nvim](https://github.com/CRAG666/betterTerm.nvim), By the way, this is the mode I currently use with this plugin)

- Reload task on the fly

- Run code in a Float window

- Run code in a tab

- Run code in a split

- Run code with toggleTerm

- Custom hooks, for example preview in files like markdown, hot reload enabled.

  see [Hooks](#hooks)

- Assign commands to projects without files in the root of the project

- Run project commands in different modes for a per projects base



## Setup



This plugin can be configured either in lua, with the `setup` function, or with json files for interopability between this plugin and the [original code runner](https://github.com/formulahendry/vscode-code-runner) vscode plugin.



### Minimal example



#### Lua



```lua

require('code_runner').setup({

  filetype = {

    java = {

      "cd $dir &&",

      "javac $fileName &&",

      "java $fileNameWithoutExt"

    },

    python = "python3 -u",

    typescript = "deno run",

    rust = {

      "cd $dir &&",

      "rustc $fileName &&",

      "$dir/$fileNameWithoutExt"

    },

    c = function(...)

      c_base = {

        "cd $dir &&",

        "gcc $fileName -o",

        "/tmp/$fileNameWithoutExt",

      }

      local c_exec = {

        "&& /tmp/$fileNameWithoutExt &&",

        "rm /tmp/$fileNameWithoutExt",

      }

      vim.ui.input({ prompt = "Add more args:" }, function(input)

        c_base[4] = input

        vim.print(vim.tbl_extend("force", c_base, c_exec))

        require("code_runner.commands").run_from_fn(vim.list_extend(c_base, c_exec))

      end)

    end,

  },

})

```



#### Json



> **Warning**

> A common mistake is using relative paths instead of absolute paths in . Use absolute paths in configurations or else the plugin won't work, in case you like to use short or relative paths you can use something like this `vim.fn.expand('~/.config/nvim/project_manager.json')`



> **Note**

> If you want to change were the code is displayed you need to specify the [`mode`]() attribute in the setup `function`



```lua

-- this is a config example

require('code_runner').setup {

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

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

}

```



## Commands



> **Note**

> To check what modes ore supported see [mode parameter](#setup).



All run commands allow restart. So, for example, if you use a command that does not have hot reload, you can call a command again and it will close the previous one and start again.



- `:RunCode`: Runs based on file type, first checking if belongs to project, then if filetype mapping exists

- `:RunCode `: Execute command from its key in current directory.

- `:RunFile `: Run the current file (optionally you can select an opening mode).

- `:RunProject `: Run the current project(If you are in a project otherwise you will not do anything,).

- `:RunClose`: Close runner(Doesn't work in better_term mode, use native plugin options)

- `:CRFiletype` - Open json with supported files(Use only if you configured with json files).

- `:CRProjects` - Open json with list of projects(Use only if you configured with json files).



Recommended mappings:



```lua

vim.keymap.set('n', 'r', ':RunCode', { noremap = true, silent = false })

vim.keymap.set('n', 'rf', ':RunFile', { noremap = true, silent = false })

vim.keymap.set('n', 'rft', ':RunFile tab', { noremap = true, silent = false })

vim.keymap.set('n', 'rp', ':RunProject', { noremap = true, silent = false })

vim.keymap.set('n', 'rc', ':RunClose', { noremap = true, silent = false })

vim.keymap.set('n', 'crf', ':CRFiletype', { noremap = true, silent = false })

vim.keymap.set('n', 'crp', ':CRProjects', { noremap = true, silent = false })

```



## Parameters



### Setup Global



This are the the configuration option you can pass to the `setup` function. To see the default values see: [`code_runner.nvim/lua/code_runner/options`](https://github.com/CRAG666/code_runner.nvim/blob/main/lua/code_runner/options.lua).



Parameters:



- `mode`: Mode in which you want to run. Are supported: "better_term", "float", "tab", "toggleterm" (type: `bool`)

- `focus`: Focus on runner window. Only works on term and tab mode (type: `bool`)

- `startinsert`: init in insert mode.Only works on term and tab mode (type: `bool`)

- `term`: Configurations for the integrated terminal

  - `position`: terminal position consult `:h windows` for options (type: `string`)

  - `size`: Size of the terminal window (type: `uint` | `float`)

- `float`: Configurations for the float window

  - `border`: Window border options (type: `string`)

    - "none": No border (default).

    - "rounded": Like "single", but with rounded corners ("â•­" etc.).

    - "solid": Adds padding by a single whitespace cell.

    - "shadow": A drop shadow effect by blending with the background.

    - For more border options see `:h nvim_open_win()` or [NeoVim API Documentation](https://neovim.io/doc/user/api.html#nvim_open_win())

  - `width`: (type: `float`)

  - `x`: (type: `float`)

  - `y`: (type: `float`)

  - `border_hl`: (type: `string`)



- `better_term`: Toggle mode replacement(Install [CRAG666/betterTerm.nvim](https://github.com/CRAG666/betterTerm.nvim))

  - `clean`: Clean terminal before launch(type: `bool`)

  - `number`: Use nil for dynamic number and set init(type: `uint?`)

  - `init`: Set a start number for executions, each execution will go to a different terminal(type: `uint?`)

    },

- `before_run_filetype`: Execute before executing a file (type: `func`)

- `filetype`: If you prefer to use lua instead of json files, you can add your settings by file type here (type: `table`)

- `filetype_path`: Absolute path to json file config (type: `absolute paths`)

- `project`: If you prefer to use lua instead of json files, you can add your settings by project here (type: `table`)

- `project_path`: Absolute path to json file config (type: `absolute paths`)



### Setup Filetypes



> **Note**

> The commands are runned in a shell. This means that you can't run neovim commands with [this](https://github.com/CRAG666/code_runner.nvim/issues/59).



#### Lua



The filetype table can take either a `string`, a `table` or a `function`.



```lua

-- in setup function

filetype = {

  java = { "cd $dir &&", "javac $fileName &&", "java $fileNameWithoutExt" },

  python = "python3 -u",

  typescript = "deno run",

  rust = { "cd $dir &&",

    "rustc $fileName &&",

    "$dir/$fileNameWithoutExt"

  },

  cs = function(...)

    local root_dir = require("lspconfig").util.root_pattern "*.csproj"(vim.loop.cwd())

    return "cd " .. root_dir .. " && dotnet run$end"

  end,

},

```



If you want to add some other language or some other command follow this structure `key = commans`.



#### Json



> **Note**

> In Json you can only pass the commands as a string



The equivalent for your json filetype file is:



```json

{

  "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",

  "python": "python3 -u",

  "typescript": "deno run",

  "rust": "cd $dir && rustc $fileName && $dir/$fileNameWithoutExt"

}

```



### Variables



> **Note**

> If you don't want to use the plugin specific variables you can use vim [filename-modifiers](https://neovim.io/doc/user/cmdline.html#filename-modifiers).



This uses some special keyword to that means different things. This is do mainly for be compatible with the original vscode plugin.



The available variables are the following:



- `file`: path to current open file (e.g. `/home/user/current_dir/current_file.ext`

- `fileName`: filename of current open file (e.g. `current_file.ext`)

- `fileNameWithoutExt`: filename without extension of current file (e.g. `current_file`)

- `dir`: path to directory of current open file (e.g. `/home/user/current_dir`)

- `end`: finish the command (it is useful for commands that do not require final autocompletion)



If you want to add some other language or some other command follow this structure `key: commans`.



### Setup Projects



There are 3 main ways to configure the execution of a project (found in the example.)



1. Use the default command defined in the filetypes file (see `:CRFiletype`or check your config). In order to do that it is necessary to define file_name.

2. Use a different command than the one set in `CRFiletype` or your config. In this case, the file_name and command must be provided.

3. Use a command to run the project. It is only necessary to define command (You do not need to write navigate to the root of the project, because automatically the plugin is located in the root of the project).



The key for each project is a pattern to match against the current filename of

the buffer. The pattern is a lua [patterns](https://www.lua.org/pil/20.3.html)

and needs to escape magic characters like `-`, `.`, `(`, etc. with a `%`.

To match the entire path to a directory you cannot simply append `/`. This is

due to `vim.fs.normalize` being used. Append `/.-` instead to prevent stripping

of `/`.



Also see [project parameters](#setup-projects) to set correctly your project commands.



#### Lua



```lua

project = {

  ["~/python/intel_2021_1"] = {

    name = "Intel Course 2021",

    description = "Simple python project",

    file_name = "POO/main.py"

  },

  ["~/deno/example"] = {

    name = "ExapleDeno",

    description = "Project with deno using other command",

    file_name = "http/main.ts",

    command = "deno run --allow-net"

  },

  ["~/cpp/example"] = {

    name = "ExapleCpp",

    description = "Project with make file",

    command = "make buid && cd buid/ && ./compiled_file"

  },

  ["~/private/.*terraform%-prod.-/.-"] = {

    name = "ExampleTerraform",

    description = "All Folders in ~/private containing \"terraform-prod\"",

    command = "terraform plan",

  },

},

```



#### Json



```json

{

  "~/python/intel_2021_1": {

    "name": "Intel Course 2021",

    "description": "Simple python project",

    "file_name": "POO/main.py"

  },

  "~/deno/example": {

    "name": "ExapleDeno",

    "description": "Project with deno using other command",

    "file_name": "http/main.ts",

    "command": "deno run --allow-net"

  },

  "~/cpp/example": {

    "name": "ExapleCpp",

    "description": "Project with make file",

    "command": "make buid && cd buid/ && ./compiled_file"

  },

  "~/private/.*terrafrom%-prod.-/.-": {

    "name": "ExampleTerraform",

    "description": "All Folders in ~/private containing \"terraform-prod\"",

    "command": "terraform plan"

  }

}

```



#### Parameters



- `name`: Project name

- `description`: Project description

- `file_name`: Filename relative to root path

- `command`: Command to run the project. It is possible to use variables exactly the same as we would in [`CRFiletype`](#commands).



> **Warning**

> Avoid using all the parameters at the same time. The correct way to use them is shown in the example and described above.



> **Note**

> Don't forget to name your projects because if you don't do so code runner will fail as it uses the name for the buffer name



## Hooks



These elements are intended to help with those commands that require more complexity.

For example, implement hot reload on markup documents.



### Preview PDF



This module allows us to send a command to compile to pdf as well as show the result every time we save the original document.



#### Usage example



```lua

{

...

    filetype = {

      -- Using pdflatex compiler

      -- tex = function(...)

      --   require("code_runner.hooks.preview_pdf").run {

      --     command = "pdflatex",

      --     args = { "-output-directory", "/tmp", "$fileName" },

      --     preview_cmd = "/bin/zathura --fork",

      --     overwrite_output = "/tmp",

      --   }

      -- end,

      -- Using tectonic compiler

      tex = function(...)

        require("code_runner.hooks.ui").select {

          Single = function()

            local preview = require "code_runner.hooks.preview_pdf"

            preview.run {

              command = "tectonic",

              args = { "$fileName", "--keep-logs", "-o", "/tmp" },

              preview_cmd = preview_cmd,

              overwrite_output = "/tmp",

            }

          end,

          Project = function()

            local cr_au = require "code_runner.hooks.autocmd"

            cr_au.stop_job()

            os.execute "tectonic -X build --keep-logs --open &> /dev/null &"

            local fn = function()

              os.execute "tectonic -X build --keep-logs &> /dev/null &"

            end

            cr_au.create_au_write(fn)

          end,

        }

      end,

      markdown = function(...)

        local hook = require "code_runner.hooks.preview_pdf"

        require("code_runner.hooks.ui").select {

          Normal = function()

            hook.run {

              command = "pandoc",

              args = { "$fileName", "-o", "$tmpFile", "-t pdf" },

              preview_cmd = preview_cmd,

            }

          end,

          Presentation = function()

            hook.run {

              command = "pandoc",

              args = { "$fileName", "-o", "$tmpFile", "-t beamer" },

              preview_cmd = preview_cmd,

            }

          end,

          Eisvogel = function()

            hook.run {

              command = "bash",

              args = { "./build.sh" },

              preview_cmd = preview_cmd,

              overwrite_output = ".",

            }

          end,

        }

      end,

  ...

}



```



![preview](https://github.com/CRAG666/dotfiles/blob/main/config/nvim/lua/plugins/dev/code_runner.lua)



In the above example we use the hook to compile markdown and latex files to pdf.

Not only that, but we also indicate in what order the resulting pdf file will be

opened. In my case it is zathura but you can use a browser if it is more

comfortable for you.



It is important that you take into account that each time you save the original file, the pdf file will be generated.



#### Parameters



- `command`: Command used to generate the pdf

- `args`: Arguments of the above command

- `preview_cmd`: Command used to open the resulting PDF

- `overwrite_output`: If for some reason you cannot define the output of the pdf file use this option to define the directory where it will be saved, and the name of the source file is concatenated with the pdf extension



##### Vars



These are variables used to be substituted for values according to each

filename.



- `$fileName`: Will be replaced by the full path of the file.

- `$tmpFile`: This variable is replaced by a dynamic name generated by lua, stored in tmp.



### Typescript hooks



This example showcases how to write a hook to run ts file, print the result in a new vertical windows and reload on save. Read the comments for more info.



```lua

-- custom function to run ts file

-- and print result in a new vertical windows

local function runTsFile(fileName)

  -- Check if the current file is a TypeScript file

  if string.match(fileName, '%.ts$') then

    -- Save the current window id

    local current_win = vim.fn.win_getid()



    -- Close previous terminal windows

    vim.cmd 'silent! wincmd w | if &buftype ==# "terminal" | q | endif'



    -- Open a vertical terminal

    vim.cmd 'vsplit term://'



    -- Run the TypeScript file and print the result

    vim.fn.termopen('ts-node ' .. fileName)



    -- Restore the focus to the original window

    vim.fn.win_gotoid(current_win)

  else

    print 'Not a TypeScript file!'

  end

end



-- hooks config

{

  filetype = {

    typescript = function()

      local cr_au = require "code_runner.hooks.autocmd"

      -- stop previous job (if has any)

      cr_au.stop_job() -- CodeRunnerJobPosWrite



      local fileName = vim.fn.expand '%:p'

      local fn = function()

        runTsFile(fileName)

      end



      -- run the command the first time

      fn()



      -- listen to bufwrite event after the first run time

      cr_au.create_au_write(fn)

    end,

  },

}

```



## Integration with other plugins



### API



These functions could be useful if you intend to create plugins around code_runner, currently only the file type and current project commands can be accessed respectively



```lua

require("code_runner.commands").get_filetype_command() -- get the current command for this filetype

require("code_runner.commands").get_project_command() -- get the current command for this project

```



### Harpoon



You can directly integrate this plugin with [ThePrimeagen/harpoon](https://github.com/ThePrimeagen/harpoon) the way to do it is through command queries, harpoon allows the command to be sent to a terminal, below it is shown how to use harpoon term together with code_runner.nvim:



```lua

require("harpoon.term").sendCommand(1, require("code_runner.commands").get_filetype_command() .. "\n")

```



## Inspirations and thanks



- The idea of this project comes from the vscode plugin [code_runner](https://marketplace.visualstudio.com/items?itemName=formulahendry.code-runner) You can even copy your configuration and pass it to this plugin, as they are the same in the way of defining commands associated with [filetypes](https://github.com/CRAG666/code_runner.nvim#add-support-for-more-file-types)

- [jaq-nvim](https://github.com/is0n/jaq-nvim) some ideas of how to execute commands were taken from this plugin, thank you very much.

- [FTerm.nvim](https://github.com/numToStr/FTerm.nvim) Much of how this README.md is structured was blatantly stolen from this plugin, thank you very much

- @adalessa, [profile](https://github.com/adalessa), Much of the code for the

  pdf preview hook was taken from a plugin it has. thank you. For the Spanish

  community he has an excellent channel on neovim, [Channel](https://www.youtube.com/@Alpha_Dev)

- Thanks to all current and future collaborators, without their contributions this plugin would not be what it is today
