What is TinyASM++?
TinyASM++ is an experimental micro-assembly language designed to mimic the feel of low-level assembly programming while adding lightweight conveniences such as symbolic variables, automatic register handling, and simplified instruction patterns. It was created for hobby OS dev, compiler experiments, and retro-style programming without requiring full CPU-specific opcodes.
It behaves like a teaching version of assembly — low-level, but not painful.
Specs
Language Type: Minimal assembly-inspired esolang
Era: ~2018–2023 experimental compilers
Execution Model: Interpreted VM or bytecode backend
Typing: None — values treated as raw integers
Primary Focus: Learn assembly-style logic without hardware constraints
Example Code (Hello World)
msg: "Hello TinyASM++"
load msg
print
halt
A math example:
load 4
load 3
add
print
halt
How It Works
TinyASM++ uses a virtual machine with registers, flags, and memory slots. Unlike real assembly, it:
- infers register allocation
- uses symbolic labels instead of raw memory addresses
- supports high-level control flow keywords
Core instructions include:
| Instruction | Meaning |
|---|---|
load |
Push value into accumulator or stack |
store |
Move value to memory label |
add, sub, mul, div
|
Arithmetic ops |
cmp |
Compare values, set flags |
jmp, jz, jnz
|
Branching |
call, ret
|
Subroutines |
halt |
Stop execution |
Some interpreters even support macros for repeated patterns.
Strengths
- Easier than real CPU assembly
- Good for teaching low-level reasoning
- Cleaner syntax and labels reduce errors
- Flexible VM design allows experimentation
Weaknesses
- Not compatible with real hardware
- No standardized implementation — varies by interpreter
- Lacks tooling, debuggers, or compilers beyond prototypes
- Still harder to read than high-level languages
Where to Run
TinyASM++ typically runs via:
- GitHub VM emulators (Python/JS/C++)
- Browser-based virtual machines
- TIO.run lightweight interpreter ports
- Retro OS-dev or emulator environments
Because there is no universal spec, code may behave differently across builds.
Should You Learn It?
- For real firmware or system programming: No
- For learning assembly concepts safely: Yes
- For compiler design hobby projects: Absolutely
- For practical engineering: Not recommended
Summary
TinyASM++ sits between pure assembly and high-level languages — a toy system for learning registers, branching, and memory manipulation without the friction of architecture-specific opcodes. It’s more educational tool than production language, but it remains a fun entry point for low-level thinking and retro computing enthusiasts.
