Vsce Script

Extension runtime with automation api for VS Code and Vim extension

Vsce Script is a VS Code extension runtime with automation api for VS Code and Vim extension.

You can use VS Code API and our library API at global for creating automatic operations with Vsce Script project at VS Code.

With those APIs, users can crete greater automatic operations than traditional Vim Macro.

Main Feature

Here are some of the features that Vsce Script provides

Open, create, and execute your Vsce Script project with javascript and typescript at vscode immediately.

A Vsce Script project is a typescript or javascript project which can be dynamic loaded by Vsce-Script extension.
You can use VS Code API at global with vsce-script extension project.
You can also install third-party npm package at extension project then execute it at vscode immediately.

Commands for search registered command at script project, you can execute or copied their command ID easily.
Custom library api for automating your VS Code command and shell command.
Custom library api for creating readable, editable and reusable macro with vim's operations.

Make Open Source Community Better!

Since vsce-script can use as an extension playground, you can fulfill your idea with it quickly. If your some of functionality that can be extract to a standalone extension. you can migrate it to a new extension package and publish it quickly. If you found some idea that can be implement for exist extensions, welcome to submit your pull request for them.

Requirements

You need to install nodejs and npm on your computer. If you want to use yarn to manage your project's package, please install it first.

Get Started

Create your project

We provide a vsce-script.createProject command for creating vsce-script template project.

You can find and execute this command at command palette (Command Palette Shortcut - MacOS: cmd+shift+p, Windows/Linux: ctrl+shift+p).

After executing this command, you need to select your project languages first, we recommend you to select typescript.

After selecting project's language, select a location of your project's directory, then click Create Project button.

At last step, please provide your custom project name.

After providing your project name (please don't provide empty string), we will creating a project at background.

You can choose use npm or yarn package for installing your packages.

Finally, you can open your script project at a new VS Code window or open it at current editor.

After you creating a project, you can use vsce-script.openProject command for opening it.

Write, compile and load your vsce-script-project!

A Vsce Script project is a nodejs project which exports activate and deactivate function on their entry point file (extension.js).

Since Vsce Script Extension injects VS Code api and lib at project's global. You can use them conveniently at Vsce Script project.

When you write down your script, just execute Vsce Script: Load Script Project on command palette.

If your project is written by typescript, extension will ask you whether compile typescript or not.

After compiling it, extension will load your project's extension.js file.

You can see registered commands by executing Vsce Script: Show All Commands on command palette.

Execute your commands

Select and execute vsce-script.showAllCommands at command palette.

You will see all commands which are registered from library's registerCommand api.

You can execute those commands with selecting menu item.

And see the result immediately.

If you just want to copy those command's id, you can use vsce-script.copyRegisteredCommandId command.

Then copy selected commandId from the menu.

Showcases

Run Automation Task

Execute Shell Command (execShell) and VS Code Command (execCmd) One by One

// Import vscode typings
import * as vsc from 'vscode';

// Injected vscode api module at global
const { window } = vscode;

const {
    commands: { registerCommand },
    automation: { execCmd, execShell, runAutomation }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.startup.frontend', async () => {
        window.showInformationMessage(`Opening apps for frontend project!`);
        // VS Code's built-in commandId for execCmd function
        const createTerminal = 'workbench.action.terminal.new';
        const openPostman_MacOS = 'open -a Postman';
        const openChrome_MacOS = 'open -a "Google Chrome" https://localhost:3000';
        await runAutomation(
            execShell(openPostman_MacOS),
            execCmd(createTerminal),
            () => {
                const terminal = vscode.window.activeTerminal;
                terminal?.sendText('yarn serve');
                return Promise.resolve();
            },
            execShell(openChrome_MacOS, { hideOutput: true }),
        );
    });
    ...
}

Manage npm package and install them easily

As a frontend developer, we often install lots of npm packages at our project. It takes a lot of effort to reinstall it at a new project. Now with Vsce-Script, you can easily define your custom addDeps command for install them.

deps.ts

For managing those config easily, we can extract those complex npm packages's config to deps.ts.

const tsDeps = ['typescript', 'ts-loader', 'ts-node'];

const webpack = ['webpack', 'webpack-cli'];

const webpackLoader = [
    'file-loader',
    'url-loader',
    'html-loader',
    'null-loader',
    'style-loader',
    'imports-loader',
    'url-loader',
    'svg-url-loader',
    'css-loader'
];

const webpackPlugin = [
    'copy-webpack-plugin',
    'add-asset-html-webpack-plugin',
    'circular-dependency-plugin',
    'compression-webpack-plugin',
    'offline-plugin',
    'terser-webpack-plugin'
];

const jest = ['[email protected]', '[email protected]'];

const reactCommonPackages = [
    '[email protected]',
    '[email protected]',
    '[email protected]',
    '[email protected]',
    '[email protected]',
    '[email protected]',
    '[email protected]'
];

const babel = ['@babel/core', 'babel-loader', '@babel/preset-env'];

const babelProdDeps = ['@babel/polyfill'];

const babelPlugins = [
    '@babel/runtime',
    '@babel/plugin-transform-runtime',
    '@babel/plugin-proposal-class-properties',
    '@babel/plugin-syntax-dynamic-import',
    '@babel/plugin-transform-modules-commonjs',
    '@babel/plugin-transform-react-constant-elements',
    '@babel/plugin-transform-react-inline-elements',
    '@babel/preset-react',
    '@babel/register',
];

const mocha = ['mocha'];

export const devDeps = {
    tsDeps,
    webpack,
    webpackLoader,
    webpackPlugin,
    jest,
    mocha,
    reactCommonPackages,
    babel,
    babelProdDeps,
    babelPlugins,
};

export const deps = {
    babelProdDeps
};

extension.ts

At extension.ts, we can define a custom command vsce-script.yarn.addDeps for installing packages. Since our library provide some interactive utilities such as dropdown and confirm. You can reduce your extension development time with those scenario.

...
// Import vscode typings
import * as vsc from 'vscode';

import { deps, devDeps } from './deps';

const {
    commands: { registerCommand },
    promise: { execShell },
    interactive: { dropdown }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.yarn.addDeps', async () => {
        const depItems = [...Object.keys(devDeps), ...Object.keys(deps)];
        const item = await dropdown('Install Deps', depItems);
        if (!item) return;
        if (deps[item]) {
            await execShell(`yarn add ${deps[item].join(' ')}`);           
        } else if (devDeps[item]){
            const depsPackages = devDeps[item].join(' ');
            await execShell(`yarn add -D ${depsPackages}`);
        }
    });
    ...
}

After writing this command and reload project, you can easily select and install groups of your dependencies.

Readable, editable and reusable macro for Vim's operation

Imagine there's a vim operation for selecting a function or any kinds of block.

You might create a macro to make this operation easier.

At VSCodeVim's .vimrc, we can define a custom keybindings vak for select it.

xmap ak <Esc>V$%$h

But it's hard to read and understand.

With javascript, we can write a editable and reusable macro with below example:

...

const {
    commands: { registerCommand },
    automation: { runMacro }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.vim.selectEntireBlock', async () => {
        const enterNormalMode = '<Esc>';
        const enterVisualLineMode = 'V';
        const moveCursorToLineEnd = '$';
        const selectMatchedBracket = '%';
        const adjustCursorPosition = '$h';
        await runMacro([
            enterNormalMode,
            enterVisualLineMode,
            moveCursorToLineEnd,
            selectMatchedBracket,
            adjustCursorPosition
        ]);
    });
    ...
}

Then you can apply this command to .vimrc.

xmap ak vsce-script.vim.selectFunctionBlock

P.S. At VSCodeVim v1.23.0, we can not edit vim's macro. All recorded macro will lost after reloading VS Code.

Dynamic macro with vim extension

Custom operation for VSCodeVim's Vim-surround plugin (Delete Surround)

...
const {
    commands: { registerCommand },
    automation: { runMacro },
    editor: { getCharUnderCursor },
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.vim.deleteSurround', async () => {
        const charUnderCursor = getCharUnderCursor();
        if (!charUnderCursor) return;
        await runMacro(['<plugds>', charUnderCursor]);
    });
    ...
}

Consider edge cases for html and xml tags:

const {
    ...
    interactive: { confirm }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.vim.deleteSurround', async () => {
        const charUnderCursor = getCharUnderCursor();
        if (!charUnderCursor) return;
        if (['<', '>'].includes(charUnderCursor)) {
            const removeXmlTag = await confirm('Remove xml tag?');
            const typeCommand = removeXmlTag ? 't' : '>';
            await runMacro(['<plugds>', typeCommand]);
        } else {
            await runMacro(['<plugds>', charUnderCursor]);
        }
    });
    ...
}

After that, we can bind this command at VSCodeVim's .vimrc.

nmap da vsce-script.vim.deleteSurround

Custom operation for VSCodeVim's Vim-surround plugin (Change Surround)

...
const {
    commands: { registerCommand },
    automation: { runMacro },
    editor: { getCharUnderCursor },
    interactive: { confirm }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    const charUnderCursor = getCharUnderCursor();
        if (!charUnderCursor) return;
        if (['<', '>'].includes(charUnderCursor)) {
            const removeXmlTag = await confirm('Remove xml tag?');
            const typeCommand = removeXmlTag ? 't' : '>';
            await runMacro(['<plugcs>', typeCommand]);
        } else {
            await runMacro(['<plugcs>', charUnderCursor]);
        }
    ...
}

After that, we can bind this command at VSCodeVim's .vimrc.

nmap ca vsce-script.vim.changeSurround

Integrate Surround extension with VSCodeVim (Workaround insertSnippet problem at VSCodeVim v0.1.23)

There's an VSCodeVim's issue with VS Code's insertSnippet command. Currently we can use custom switchToInsertModeSelection to force VS Code switch and keep visual mode selection at insert mode.

When we execute any commands with insertSnippet command at Vim's insert mode, everything works well.

Below is an example for creating custom command for Surround extension.

...

const {
    commands: { registerCommand },
    vim: { switchToInsertModeSelection }
} = lib;

export function activate(context: vsc.ExtensionContext) {
    ...
    registerCommand('vsce-script.vim.surroundWith', async () => {
        await switchToInsertModeSelection();
        vscode.commands.executeCommand('surround.with');
    });
    ...
}

After defining this command, you can easily rebind this command at VSCodeVim's visualModeKeybindings.

xmap <leader>s vsce-script.vim.surroundWith

Disable specific extensions at new window

Here's an VS Code's unsolved issue for enable/disable specific extension from API or commands.

See: How to enable / disable extension from API or commands

Here's a scenario of disabling specific extensions.

Imagine we have a frontend project with react snippet, it will jump snippet completion at any kinds of typescript project at VS Code.

When we are developing NodeJS project, we might be bothered with unused react snippet.

Since VS Code provide an undocument options for disabling extension with code command for trobleshooting.

If we want to disable an extension, we can use below command for disable an extension.

code --disable-extension <ext-id>

However, disabled command only works with VS Code's window which is opened from that code command.

So we need to invoke this command for disabling a set of extensions before opening our project every time.

With Vsce Script, we can create below utility function for making this command and it's options more easier.

// On macOS, first time you need to run `install Code command` at vscode manually  
// Limitation: you need to reopen VS Code with this function for disabling extensions
async function reopenForDisablingExtensions(reopenWorkspacePath: string, extensions: string[]) {
    const disableExtensions = extensions.map(extId => `--disable-extension ${extId}`).join(' ');
    const codeCommand = `code ${disableExtensions} -n ${reopenWorkspacePath}`;
    const closeWindow = `workbench.action.closeWindow`;
    await runAutomation(
        execShell(codeCommand),
        execCmd(closeWindow)
    );
}

Then we can use this function with our custom command.

registerCommand('vsce-script.workspace.disableReactExtensions', async () => {
    const workspace = await getCurrentWorkspaceFolder();
    if (!workspace) return;
    const workspacePath = workspace.uri.fsPath ?? '.');
    const reactExtensions = [
        'dsznajder.es7-react-js-snippets',
        'discountry.react-redux-react-router-snippets'
    ];
    await reopenForDisablingExtensions(workspacePath, disableExtensions);
});
