Attention: Here be dragons

This is the latest (unstable) version of this documentation, which may document features not available in or compatible with released stable versions of Redot.

Using an external text editor

This page explains how to code using an external text editor.

Note

To code C# in an external editor, see the C# guide to configure an external editor.

Redot can be used with an external text editor, such as Sublime Text or Visual Studio Code. Browse to the relevant editor settings: Editor > Editor Settings > Text Editor > External

Text Editor > External section of the Editor Settings

There are two text fields: the executable path and command-line flags. The flags allow you to integrate the editor with Redot, passing it the file path to open and other relevant arguments. Redot will replace the following placeholders in the flags string:

Field in Exec Flags	Is replaced with
{project}	The absolute path to the project directory
{file}	The absolute path to the file
{col}	The column number of the error
{line}	The line number of the error

Some example Exec Flags for various editors include:

Editor	Exec Flags
Geany/Kate	{file} --line {line} --column {col}
Atom	{file}:{line}
JetBrains Rider	{project} --line {line} {file}
Visual Studio Code	{project} --goto {file}:{line}:{col}
Vim (gVim)	"+call cursor({line}, {col})" {file}
Emacs	emacs +{line}:{col} {file}
Sublime Text	{project} {file}:{line}:{column}

Note

For Visual Studio Code on Windows, you will have to point to the code.cmd file.

For Emacs, you can call emacsclient instead of emacs if you use the server mode.

Using External Editor in Debugger

Using external editor in debugger is determined by a separate option in settings. For details, see Script editor debug tools and options.

Official editor plugins

We have official plugins for the following code editors:

• Visual Studio Code

• Emacs

LSP/DAP support

Redot supports the Language Server Protocol (LSP) for code completion and the Debug Adapter Protocol (DAP) for debugging. You can check the LSP client list and DAP client list to find if your editor supports them. If this is the case, you should be able to take advantage of these features without the need of a custom plugin.

To use these protocols, a Redot instance must be running on your current project. You should then configure your editor to communicate to the running adapter ports in Redot, which by default are 6005 for LSP, and 6006 for DAP. You can change these ports and other settings in the Editor Settings, under the Network > Language Server and Network > Debug Adapter sections respectively.

Below are some configuration steps for specific editors:

Visual Studio Code

You need to install the official Visual Studio Code plugin.

For LSP, follow these instructions to change the default LSP port. The connection status can be checked on the status bar:

For DAP, specify the debugServer property in your launch.json file:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "GDScript Redot",
            "type": "godot",
            "request": "launch",
            "project": "${workspaceFolder}",
            "port": 6007,
            "debugServer": 6006,
        }
    ]
}

Emacs

Check the official instructions to configure LSP, and DAP.
