doof

library0.0.2jsnpmunverified

A TypeScript-like language transpiler targeting C++, JavaScript, and VM bytecode. Version 0.0.2 is the current stable release with an experimental development cadence. It offers a familiar TypeScript syntax for classes, type annotations, and templates, but transpiles to idiomatic C++ with optional runtime support, or JavaScript or abstract VM bytecode. Key differentiators include cross-language output from a single source, integrated C++ compile-and-run, and a format/lint tool. Note: Very early-stage, with limited ecosystem and documentation.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Transpiler

✓ import { Transpiler } from 'doof'

✗ const Transpiler = require('doof').Transpiler

CommonJS require works but ESM is preferred.

transpile

✓ import { transpile } from 'doof'

✗ import transpile from 'doof'

transpile is a named export, not default.

TranspilerOptions

✓ import type { TranspilerOptions } from 'doof'

✗ import { TranspilerOptions } from 'doof'

TranspilerOptions is a type, should be imported using 'type' modifier to avoid runtime inclusion.

Shows both simple transpile and multi-file project transpilation with different targets.

import { transpile, Transpiler } from 'doof'; // Simple single-file transpilation const result = transpile( `class Greeter { name: string; greet(): string { return \`Hello, \${this.name}!\`; } } function main(): int { let greeter = Greeter { name: "World" }; print(greeter.greet()); return 0; }`, { target: 'cpp' } ); console.log(result.code); // Multi-file project transpilation const transpiler = new Transpiler({ target: 'js', namespace: 'myapp' }); transpiler.transpileProject(['file1.do', 'file2.do']).then(projectResult => { projectResult.files.forEach(f => console.log(f.path, f.code)); });

Debug

Known issues

gotchaThe default target is C++ (cpp), not JavaScript.

fix

Explicitly pass {target: 'js'} when you want JavaScript output.

affects: >=0.0.1

gotchaPackage version is 0.0.2, very early stage. Breaking changes can happen with minor updates.

fix

Pin to exact version in package.json: "doof": "0.0.2".

affects: >=0.0.1

gotchaThe transpiled C++ output requires the included runtime files (doof_runtime.cpp/.h) to compile.

fix

Copy doof_runtime.cpp and doof_runtime.h to your project and compile them with your generated code.

affects: >=0.0.1

gotchaCLI options have changed between minor versions; '--target' requires a value (cpp/js/vm) and is not optional.

fix

Use -t js or --target js; do not omit the flag.

affects: >=0.0.1

Errors

Common errors & fixes

Error: Cannot find module 'doof/runtime'

Trying to directly import runtime files without proper path.

fix

Use 'doof' package only for the transpiler and manually copy runtime files from node_modules/doof/.

TypeError: transpile is not a function

Using default import instead of named import.

fix

Change 'import transpile from "doof"' to 'import { transpile } from "doof"'.

Error: Unknown target 'javascript'

Using 'javascript' instead of 'js' as target.

fix

Use target: 'js' (not 'javascript').

error: cannot find class "Array"

Using non-existent built-in types in doof language.

fix

Use doof's built-in types: int, float, string, bool, array, map.
