# AI Agent Onboarding Guide
|
|
|
|
> If you are an AI reading this: welcome. This project is designed to be worked on by AI agents. Everything you need is in this repo. No human required.
|
|
|
|
## What is this project?
|
|
|
|
**Bara Lang** is a Clojure dialect that compiles to Nim, then to C, then to native binaries.
|
|
|
|
Current state: **Working compiler + REPL + macro system + file/git ops + Nim interop.**
|
|
|
|
## Quick Start (for AI agents)
|
|
|
|
```bash
|
|
# 1. Build
|
|
make build
|
|
|
|
# 2. Run tests
|
|
make test
|
|
|
|
# 3. Check everything works
|
|
make check
|
|
|
|
# 4. Try the REPL
|
|
./cljnim repl

|
|
## How to add a feature
|
|
|
|
### Step 1: Pick a task from TASKS.md
|
|
```bash
|
|
cat TASKS.md
|
|
```
|
|
Each task has:
|
|
- **Files to modify** — exact Nim/Clojure files
|
|
- **Acceptance criteria** — how to verify it works
|
|
- **Complexity** — Small / Medium / Large
|
|
|
|
### Step 2: Implement
|
|
|
|
Most tasks follow this pattern:
|
|
|
|
1. **If adding a Clojure core function** (e.g. `range`, `str`):
|
|
- Add the Nim implementation in `lib/cljnim_runtime.nim`
|
|
- Add the name mapping in `src/emitter.nim` → `runtimeName()`
|
|
- Add a test in `tests/test_emitter.nim`
|
|
- Add an example in `examples/`
|
|
|
|
2. **If adding emitter special form support** (e.g. `loop`/`recur`):
|
|
- Modify `src/emitter.nim` → `emitSpecialForm()`
|
|
- Add test in `tests/test_emitter.nim`
|
|
|
|
3. **If adding a macro** (e.g. `lazy-seq`):
|
|
- Add macro implementation in `src/macros.nim` → `initBuiltinMacros()`
|
|
- Add test
|
|
|
|
### Step 3: Test your change
|
|
|
|
```bash
|
|
# Build after any change
|
|
make build
|
|
|
|
# Run all tests
|
|
make test
|
|
|
|
# Run a specific example to verify
|
|
./cljnim run examples/hello.clj
|
|
./cljnim run examples/your_new_example.clj
|
|
```
|
|
|
|
### Step 4: Commit
|
|
|
|
```bash
|
|
# From Clojure code:
|
|
(git/commit "Your commit message")
|
|
(git/push)
|
|
```
|
|
|
|
Or from shell:
|
|
```bash
|
|
git add -A
|
|
git commit -m "Your commit message"
|
|
git push
|
|
```
|
|

## Key Files for AI Agents
|
|
|
|
| If you want to... | Modify this file |
|
|
|---|---|
|
|
| Add a Clojure function | `lib/cljnim_runtime.nim` + `src/emitter.nim` |
|
|
| Add a special form | `src/emitter.nim` |
|
|
| Add a macro | `src/macros.nim` |
|
|
| Add REPL command | `src/repl.nim` |
|
|
| Fix a reader bug | `src/reader.nim` |
|
|
| Add file/git op | `lib/cljnim_runtime.nim` + `src/emitter.nim` |
|
|
|
|
## How the compiler works (in 5 steps)
|
|
|
|
1. **Reader** (`src/reader.nim`): Text → `CljVal` AST
|
|
2. **Macros** (`src/macros.nim`): Expands macros on `CljVal` AST
|
|
3. **Emitter** (`src/emitter.nim`): `CljVal` AST → Nim source code
|
|
4. **Nim compiler**: Nim → C
|
|
5. **C compiler**: C → binary
|
|
|
|
## Testing Strategy
|
|
|
|
Every change MUST be tested with:
|
|
1. `make test` — runs Nim unit tests
|
|
2. `make check` — runs examples
|
|
3. Manual REPL test if relevant: `./cljnim repl --json`
|
|
|
|
## Common Mistakes
|
|
|
|
1. **Forgetting `initBuiltinMacros()`**: If you add a macro but it doesn't expand, check that `initBuiltinMacros()` is called before compilation. It's called in `src/cljnim.nim` and `src/repl.nim`.
|
|
|
|
2. **Not adding to `runtimeName`**: If you add a runtime function in `lib/cljnim_runtime.nim` but Clojure can't find it, add the name mapping in `src/emitter.nim` → `runtimeName()`.
|
|
|
|
3. **String escaping**: Clojure strings with `\n` or quotes may break Nim code generation. The emitter needs to escape strings properly.
|
|
|
|
## Communication Protocol
|
|
|
|
When you finish a task, update:
|
|
1. `TASKS.md` — mark the task as done
|
|
2. `docs/ROADMAP.md` — update if phase completed
|
|
3. Commit with descriptive message
|

## Questions?
|
|
|
|
Read `docs/ARCHITECTURE.md` for deep technical details.
|
|
Read `docs/API.md` for REPL protocol reference.
|
|
Read `docs/GUIDE.md` for user-facing features.
