Theoretical problem

When resolving script imports, the code doesn't deals with empty string imports, and relies on nullptr :

This works because when reading script objects, empty strings (a single \0 character) are replaced by a nullptr :

But when writing a script object, we don't treat the nullptr case, so if you read a script object, and want to write it back to a file, this will break here :

Building an AGS game

Building an AGS game

Ideally, while the project files holds the game information in the form that is the most convenient by the Editor used by the game developer, the game data represents this information in the most convenient form for the Engine.

Building a game is to transform information that describes the game to the form convenient for the Engine. This document describes how a platform agnostic AGS game is built.

Guide to writing an Atom language grammar

A guide to writing a language grammar (TextMate) in Atom

Tree sitter

  • Atom is transitioning to an entirely new way of defining grammars using tree-sitter. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful. To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers
