AstraC Language Support for VS Code

Syntax highlighting, snippets, and language configuration for the AstraC compiler and assembler.

Languages

Features

• AC: full keyword/type/pointer highlighting, preprocessor directives (#include, #define, #if/#elif/#else, #push/#pop), numeric literals (hex/binary/float/char), string escapes, operators, and snippets.
• AS: all 200 instruction mnemonics (full i386 ISA), every register (GPR/segment/control/debug/FPU/MMX/SSE), section & mode directives (.data, .rodata, .code, .use16, .use32, .org, .times), size overrides (BYTE/WORD/DWORD/REAL4 PTR), local labels (@@, @f, @b), location counters ($, $$), and snippets.

IntelliSense

The extension ships a language server for AC that provides:

• Completion for globals, functions, typedef/struct/union/enum names, and #define macros.
• Hover (type info) and Go to Definition for those symbols.
• Outline (documentSymbol) of the top-level declarations in a file.

#include directives are resolved transitively, so symbols from any included file are available everywhere from the point of the #include onward. Visibility follows AC's storage classes: static (and unqualified file-scope) globals are visible across files, while local globals stay private to the file that declares them.

Usage

Install the .vsix package, or run the extension locally in the Extension Development Host.

To build from source: npm install && npm run compile, then press F5 (or run vsce package to produce a .vsix).
