cronus-npc-parser

A JS parser for Cronus/rAthena npcs.

I don't know if there is any decent use case worth developing with it. A few cases I thought about are:

• Build a JS script interpreter with a decent UI/UX for I/O;
• Build an IDE with debugging utilities (superset of the idea above);
• Build a prettify and/or obfuscation tool;
• Build a tool to help with translations;
• Build a script creator like RPG Maker's script creator.

Goals

• Being able to parse script expressions and script code, expecting the exact same result rAthena/Cronus would produce.
• Being able to parse npc headers to list npcs in a file. This should not parse script code, but instead just skip and keep it as a string.

Secondary goals

• Produce better error messages during lexical/syntactical analysis.
• Store line (and maybe even column) number on the original file for each node in the AST.
• Include, in the AST, the comments found in the script code.
