Mnemonimov Assembly — Syntax Highlighting

VS Code syntax highlighting for MISA (the Mnemonimov Instruction Set Architecture), the custom assembly language used in the Mnemonimov fantasy console.

Features

Provides full syntax highlighting for .mnemo and .asm files, covering the complete MISA instruction set:

• Instructions — all arithmetic, floating-point, vector, logic/bitwise, bit-manipulation, data-transfer, control-flow, drawing, and system instructions
• Registers — general-purpose (t0–t15, a0–a15, s0–s31) and special-purpose (zr, cr, ea, pa, ba, sp, fp, pc)
• Directives — def, undef, emb, res, bmk, sbmk
• Types — i8t, u8t, i16t, u16t, i32t, u32t, f32t, string, file
• Comparison conditions — eq, neq, lt, lte, gt, gte, ltu, lteu, gteu, feqa, fneqa, flt, fgt, fnan, finf
• System calls — all SYS_* identifiers (SYS_PRINT_STRING, SYS_DRAW_TEXTURE, SYS_GET_INPUT, …)
• Built-in symbols — true, false, PI, TAU, EXP1, INF, NAN, SCREEN_WIDTH, SCREEN_HEIGHT, BTN_*, $
• Numeric literals — decimal, hexadecimal (0x), binary (0b), octal (0o), floating-point, with underscore separators
• String literals — double-quoted strings with escape sequences
• Labels — global (name:), local (.name:), and reusable (@name: / @name+ / @name-)
• Comments — regular (#) and documentation (##)
• Expression operators — arithmetic, bitwise, logical, and vector range (..)
