A complete LOLCODE 1.2 compiler for .NET 10. Write LOLCODE, get real .NET assemblies.

HAI 1.2
  VISIBLE "OH HAI! I CAN HAZ COMPILER!"
KTHXBYE

✨ What's Included

Full LOLCODE 1.2 Language Support

  • Variables & Types — NUMBR (int), NUMBAR (float), YARN (string), TROOF (bool), NOOB (null)
  • Math — SUM OF, DIFF OF, PRODUKT OF, QUOSHUNT OF, MOD OF, BIGGR OF, SMALLR OF
  • Booleans — BOTH OF, EITHER OF, WON OF, NOT, ALL OF, ANY OF
  • Comparison — BOTH SAEM, DIFFRINT (no auto-casting, per spec)
  • Conditionals — O RLY? / YA RLY / MEBBE / NO WAI / OIC
  • Switch — WTF? / OMG / OMGWTF with fall-through semantics
  • Loops — IM IN YR with UPPIN, NERFIN, TIL, WILE, GTFO
  • Functions — HOW IZ I / IF U SAY SO / FOUND YR / I IZ func MKAY
  • Casting — MAEK x A NUMBR, x IS NOW A YARN
  • Strings — SMOOSH concatenation, :{var} interpolation, escape sequences (:), :>, ::, :", :o)
  • I/O — VISIBLE (print with infinite arity), GIMMEH (read input)
  • Comments — BTW (line), OBTW...TLDR (block)
  • IT — Implicit per-scope variable, auto-returned from functions

Roslyn-Inspired Compiler Architecture

Hand-rolled, multi-phase compiler — no parser generators, no transpiling to C#:

Source (.lol) → Lexer → Parser → Binder → Lowerer → CodeGenerator → .NET DLL
  • Rich diagnostics with source location, line/column info, and LOLxxxx error codes
  • Immutable syntax and bound trees
  • Each phase independently testable

MSBuild SDK Integration

Build LOLCODE with standard .NET tooling:

dotnet new install Lolcode.NET.Templates
dotnet new lolcode -n MyApp
cd MyApp
dotnet run    # → HAI WORLD!

File-Based Apps

No project file needed:

echo '#:sdk Lolcode.NET.Sdk
HAI 1.2
  VISIBLE "HAI WORLD!"
KTHXBYE' > hello.lol
dotnet run --file hello.lol

16 Sample Programs

Organized into categories with dotnet run support:

  • Basics (9) — hello-world, variables, math, conditionals, loops, functions, string-ops, casting, switch
  • Programs (4) — fizzbuzz, fibonacci, recursion, string-calculator
  • Games (3) — guessing-game, adventure-game, arena-game

289 Tests Across 2 Projects

  • Unit tests — Lexer (32), Parser (25), Runtime (86)
  • End-to-end tests — 19 category classes covering every language feature
  • SDK integration tests — all 16 samples verified
