setlxjs-transpiler

library1.4.0jsnpmunverified

A transpiler that converts SetlX (a set-theoretic programming language) source code into JavaScript. Version 1.4.0 is the latest stable release; the project is in active development with irregular release cadence. It aims to bring the expressive set operations and functional programming paradigms of SetlX to the JavaScript ecosystem. Differentiated from general transpilers by its specific focus on SetlX language constructs, including sets, tuples, and comprehensions. Originally part of the setlxjs project with CLI and lib packages. Requires separate setlxjs-lib runtime library for execution.

Verified usage

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

transpile

✓ import { transpile } from 'setlxjs-transpiler'

✗ const transpile = require('setlxjs-transpiler').transpile

Default export is an object with transpile function; only named import is supported.

default

✓ import transpiler from 'setlxjs-transpiler'

✗ import { default } from 'setlxjs-transpiler'

Default import is the main module object; transpile is a property.

transpile (CommonJS)

✓ const { transpile } = require('setlxjs-transpiler')

✗ const transpile = require('setlxjs-transpiler')

In CommonJS, package exports an object; must destructure or use property access.

Demonstrates transpiling a basic SetlX program with set operations into JavaScript using the transpile function.

import { transpile } from 'setlxjs-transpiler'; const setlxCode = ` s := {1,2,3}; t := {3,4,5}; print(s * t); // intersection `; try { const jsCode = transpile(setlxCode); console.log(jsCode); // Output JavaScript that can be evaluated with setlxjs-lib } catch (error) { console.error('Transpilation failed:', error.message); }

Debug

Known issues

gotchaThe transpiled JavaScript requires the setlxjs-lib runtime library to be available in the execution environment.

fix

Install setlxjs-lib and include its bundle in your project (e.g., via script tag or require).

affects: >=1.0.0

breakingVersion 1.0.0 adopted ESM-style exports; old CommonJS require patterns stopped working.

fix

Use dynamic import or update to Node.js with ESM support. For CommonJS, use 'const { transpile } = require('setlxjs-transpiler');'.

affects: >=1.0.0

deprecatedThe package no longer bundles the CLI. Use setlxjs-cli separately for command-line usage.

fix

Install setlxjs-cli globally: 'npm install -g setlxjs-cli'.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'setlxjs-lib'

The transpiled code expects the runtime library setlxjs-lib but it is not installed.

fix

Run 'npm install setlxjs-lib' in your project that will execute the transpiled output.

TypeError: transpile is not a function

Using CommonJS require without destructuring, obtaining the module object instead of the function.

fix

Use 'const { transpile } = require('setlxjs-transpiler');' or 'import { transpile } from 'setlxjs-transpiler';'.

SyntaxError: Unexpected token 'export'

The package uses ESM exports but is being required in a CommonJS environment without transpilation.

fix

Use dynamic import() in CommonJS, or use a bundler that handles ESM/CJS interop.
