plc-sim/client/node_modules/muggle-string

This library aims to provide codegen helpers and data structure for Vue language plugin API v1.x that does not depend on Volar runtime.

Why "Muggle"?

A better situation is Volar can use magic-string on the Vue plugin API, but currently can't do this easily.

This solution is just for Vue language plugin API v1.x and planned to be deprecate in v2.

Usage

The example is base-on magic-string readme.

<script>problems = 99</script>

<more-script lang="js">console.log( answer )</more-script>

import {
	toString,
	replace,
} from 'muggle-string';

/** @type {import('@volar/vue-language-core').VueLanguagePlugin} */
const plugin = () => {
	return {
		name: 'example-vue-language-plugin',
		version: 1,
		resolveEmbeddedFile(fileName, sfc, embeddedFile) {
			if (embeddedFile.fileName.replace(fileName, '').match(/^\.(js|ts|jsx|tsx)$/)) {

				const s = embeddedFile.content;
				toString(s); // 'problems = 99'

				replace(s, 'problems', 'answer');
				toString(s); // 'answer = 99'

				replace(s, '99', '42');
				toString(s); // 'answer = 42'

				// add string by Array method directly
				s.unshift('var ');
				s.push(';');
				toString(s); // 'var answer = 42;'

				for (const block of sfc.customBlocks) {
					if (block.type === 'more-script') {
						s.push([
							block.content, // text to add
							block.name, // source
							0, // content offset in source
							{
								// language capabilities to enable in this segment
								hover: true,
								references: true,
								definition: true,
								diagnostic: true,
								rename: true,
								completion: true,
								semanticTokens: true,
							},
						]);
						toString(s); // 'var answer = 42;console.log( answer )'
					}
				}
			}
		}
	};
};
