luast-util-from-luaparse

Convert legacy luaparse AST to luast format.

What is this?

This package converts the PascalCase AST emitted by luaparse's legacy mode (e.g. Chunk, LocalStatement, Identifier) into the camelCase, unist-compliant luast format (e.g. root, localStatement, identifier). It also converts position data to the unist position format (1-indexed columns).

Install

npm install @friday-friday/luast-util-from-luaparse

Use

import luaparse from '@friday-friday/luaparse'
import {fromLuaparse} from '@friday-friday/luast-util-from-luaparse'

// Parse in legacy mode
const legacy = luaparse.parse('local x = 1', {
  locations: true,
  ranges: true
})

// Convert to luast
const tree = fromLuaparse(legacy)
// tree.type === 'root'
// tree.body[0].type === 'localStatement'
