llp-script

library0.5.0jsnpmunverified

A simple and safe JavaScript subset transpiler designed for LLP (Low-Latency Platform) customization, currently at version 0.5.0. The project appears to be in early development with a single commit on GitHub. It provides a transpiler that converts a restricted subset of JavaScript to compatible code, focusing on safety and simplicity for embedded customization scenarios. Compared to more comprehensive transpilers like Babel or TypeScript, llp-script is minimal and targeted. The release cadence is unknown; the latest version is 0.5.0, and there is no recent activity.

Code

Verified usage

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

transpile

✓ import { transpile } from 'llp-script'

✗ const transpile = require('llp-script').transpile

The package is ESM-only. CommonJS require is not supported.

parse

✓ import { parse } from 'llp-script'

✗ import { parse } from 'llp-script/parse'

Only named exports are provided. Default export is not available.

default

✓ import llp from 'llp-script'

✗ import * as llp from 'llp-script'

There is a default export that is the transpile function itself, but using named import for transpile is more explicit.

Shows basic usage of transpiling a file from llp-script subset to JavaScript, with error handling.

import { transpile } from 'llp-script'; import { readFileSync } from 'fs'; const code = readFileSync('./script.llp', 'utf8'); try { const result = transpile(code, { comments: false }); console.log(result.code); } catch (err) { console.error('Transpilation failed:', err); }

Debug

Known issues

breakingVersion 0.5.0 changed the API from synchronous to callback-based for transpile.

fix

Update calls to transpile to use callback or promise: transpile(code, callback)

affects: <0.5.0

deprecatedThe default export was deprecated in 0.4.0; use named export transpile instead.

fix

Replace default import with named import: import { transpile } from 'llp-script'

affects: >=0.4.0

gotchaTranspiler does not support ES6+ syntax like arrow functions or let; use only var and function declarations.

fix

Ensure input code uses only the supported subset: var, function, if, while, for, etc.

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module 'acorn'

Missing dependency acorn is not installed.

fix

Run npm install acorn

TypeError: transpile is not a function

Incorrect import: using default import instead of named import.

fix

Use import { transpile } from 'llp-script'

SyntaxError: Unexpected token =>

Input code uses arrow functions which are not in the supported subset.

fix

Rewrite arrow function as a regular function expression.
