Dasm macro assembler for VSCode

This is a dasm macro assembler extension for Visual Studio Code. It aims to provide the following in-editor features:

• Powerful assembly source editing for the 6502 (and others) using the dasm macro assembler
• Assembling and exporting generated byte code (ROMs)
• Running Atari VCS 2600 code with full debugging and run-as-you-type abilities

Notice, however, that this extension is a work-in-progress and that many features do not work yet. More importantly, it doesn't yet create a separate ROM file nor does it open the emulator preview tab. You would need to rely on the command-line dasm and the Stella emulator (or others) for that.

See more about the motivation for this extension in the Why Atari? document.

Acknowledgements

This extension uses the original dasm macro assembler via dasmjs, an emscripten-compiled version of the original C code. This is ran on the background, as a language server tracked as a separate part of this repository.

And finally, this extension was heavily inspired by the 8bitworkshop web-based Atari development IDE (but shares no code with it). One could say this extension is an attempt to create a similar Atari development experience, but within a dedicated standalone desktop application. Buy their book to show your support.
