Nim Extension

This extension adds language support for the Nim language to VS Code, including:

Syntax Highlight (nim, nimble, nim.cfg)
Code Completion
Signature Help
Goto Definition
Find References
File outline
Build-on-save
Workspace symbol search
Quick info
Problem Matchers for nim compiler and test output
Nim check result reported in Nim output channel (great for macro development)

Using

First, you will need to install Visual Studio Code 1.27.0 or higher. In the command palette (cmd-shift-p) select Install Extension and choose nim-lang.org.

The following tools are required for the extension:

Nim compiler - http://nim-lang.org

Note: It is recommended to turn Auto Save on in Visual Studio Code (File -> Auto Save) when using this extension.

Options

The following Visual Studio Code settings are available for the Nim extension. These can be set in user preferences (cmd+,) or workspace settings (.vscode/settings.json).

nim.buildOnSave - perform build task from tasks.json file, to use this options you need declare build task according to Tasks Documentation, for example:

{
    "taskName": "Run module.nim",
    "command": "nim",
    "args": ["c", "-o:bin/${fileBasenameNoExtension}", "-r", "${fileBasename}"],
    "options": {
        "cwd": "${workspaceRoot}"
    },
    "type": "shell",
    "group": {
        "kind": "build",
        "isDefault": true
    }
}

nim.lintOnSave - perform the project check for errors on save
nim.project - optional array of projects file, if nim.project is not defined then all nim files will be used as separate project
nim.licenseString - optional license text that will be inserted on nim file creation

Example

{
    "nim.buildOnSave": false,
    "nim.buildCommand": "c",
    "nim.lintOnSave": true,
    "nim.project": ["project.nim", "project2.nim"],
    "nim.licenseString": "# Copyright 2020.\n\n"
}

Commands

The following commands are provided by the extension:

Nim: Run selected file - compile and run selected file, it uses c compiler by default, but you can specify cpp in nim.buildCommand config parameter. This command available from file context menu or by F6 keyboard shortcut.
Nim: Restart nimsuggest - restart nimsuggest process when using nimsuggest.

Debugging

Visual Studio Code includes a powerful debugging system, and the Nim tooling can take advantage of that. However, in order to do so, some setup is required.

Setting up

First, install a debugging extension, such as CodeLLDB, and any native packages the extension may require (such as clang and LLDB).

Next, you need to create a tasks.json file for your project, under the .vscode directory of your project root. Here is an example for CodeLLDB:

// .vscode/tasks.json
{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "nim: build current file (for debugging)",
            "command": "nim",
            "args": [
                "compile",
                "-g",
                "--debugger:native",
                "-o:${workspaceRoot}/bin/${fileBasenameNoExtension}",
                "${relativeFile}"
            ],
            "options": {
                "cwd": "${workspaceRoot}"
            },
            "type": "shell",
        }
    ]
}

Then, you need to create a launch configuration in the project's launch.json file. Again, this example works with CodeLLDB:

// .vscode/launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "nim: debug current file",
            "preLaunchTask": "nim: build current file (for debugging)",
            "program": "${workspaceFolder}/bin/${fileBasenameNoExtension}",
            "args": [],
            "cwd": "${workspaceFolder}",
        }
    ]
}

You should be set up now to be able to debug from a given file in the native VS Code(ium) debugger.

Code Completion

This extension relies on the Nim Language Server for code completion. You can read more about it here

Developing the Extension

If this is the first time you're building the extension on your machine, do an npm install to get the dependencies
You should also copy (or create a symlink to) the nimsuggest directory from the Nim compiler sources into src/nimsuggest
Press F5 or whatever your Run -> Start Debugging command short cut is
If prompted choose launch Extension
This launches a new VS Code Window which is running your patched extension
You can open a Nim code base to try it out
- If you want to try it out on the extension source itself, create a new workspace and add the source as a folder to the workspace so VS Code doesn't take you back to the development window

Alternatively, feel free to give side-loading a shot.

Side-loading the Extension

Run nimble vsix to build the extension package to out/nimvscode-<version>.vsix
Run nimble install_vsix if you have VS Code on PATH, otherwise select Install from VSIX from the command palette (cmd-shift-p) and choose out/nimvscode-<version>.vsix.

Acknowledgments

This extension started out as a fork of the @saem extension vscode-nim which was a port of an extension written in TypeScript for the Nim language.

Thank you Saem for your work and letting us build on top of it.
