{"id":17651,"library":"firescript-parser","title":"Firescript Language Parser","description":"The `firescript-parser` package provides a parser module for the Firescript language, designed to convert Firescript source code into an Abstract Syntax Tree (AST). As of its current version 0.15.0, both the language and its parser are actively under development and are not yet recommended for production use. Firescript itself is an indentation-based scripting language that compiles to clean, readable JavaScript, emphasizing strict syntax and dynamic typing. The parser's release cadence is irregular, closely tied to the evolving specifications of the Firescript language. Its primary differentiator is its specific utility for the Firescript ecosystem, rather than being a general-purpose parser for established languages.","status":"active","version":"0.15.0","language":"javascript","source_language":"en","source_url":null,"tags":["javascript","firescript","parser","fire","fireparser"],"install":[{"cmd":"npm install firescript-parser","lang":"bash","label":"npm"},{"cmd":"yarn add firescript-parser","lang":"bash","label":"yarn"},{"cmd":"pnpm add firescript-parser","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"The primary `Parser` class is exported as the default export.","wrong":"import { Parser } from 'firescript-parser'","symbol":"Parser","correct":"import Parser from 'firescript-parser'"},{"note":"When using CommonJS, explicitly access the `.default` property for the Parser class due to ESM interoperability.","wrong":"const Parser = require('firescript-parser');","symbol":"Parser (CommonJS)","correct":"const Parser = require('firescript-parser').default;"},{"note":"While the class inside is often named `FirescriptParser`, the default import directly exposes it as `Parser` by convention.","wrong":"import FirescriptParser from 'firescript-parser'; new FirescriptParser()","symbol":"FirescriptParser (Class access)","correct":"import Parser from 'firescript-parser'; new Parser()"}],"quickstart":{"code":"import Parser from 'firescript-parser';\n\nconst parser = new Parser();\ntry {\n  const firescriptCode = \"const foo = 'bar'\\nlet baz = 10\";\n  const ast = parser.parse(firescriptCode);\n  console.log('Successfully parsed Firescript code.');\n  console.log(JSON.stringify(ast, null, 2));\n  // Example: Accessing part of the AST (structure may vary)\n  // if (ast && ast.body && ast.body.length > 0) {\n  //   console.log('First statement type:', ast.body[0].type);\n  // }\n} catch (error) {\n  console.error('Parsing failed:', error.message);\n}","lang":"javascript","description":"Demonstrates how to import the `Parser` class, instantiate it, and parse a basic Firescript code snippet into an AST."},"warnings":[{"fix":"Monitor the project's GitHub repository for updates and changelogs.
