Add standard library modules: - Std::String: strlen, strcmp, concat, copy, starts_with wrappers - Std::Map: linear-probing hash map with String keys, int values Add error handling: - Result and Option algebraic enum examples - ? try operator for automatic error propagation in HIR lowering Compiler bugfixes: - Fix sizeof() for user-defined structs (new hSizeOf HIR node) - Fix HIR type lowering for char8, bool8, int8, uint8, etc. - Fix let statement lowering for pointer types (*char8 → int* bug) - Fix PrintInt ABI mismatch (int64_t → int in io.c) - Fix Makefile test bug (_test_tmp_pkg already exists) Documentation: - Rewrite README.md with features, examples, project structure - Add docs/LanguageRef.md — complete language reference - Add docs/Stdlib.md — standard library documentation - Add docs/BuildAndTest.md — build and test guide New examples: strings, map, result_option, try_operator (13 total)

# Build and Test Guide
|
|
|
|
This guide covers building the Bux bootstrap compiler, creating projects, and running tests.
|
|
|
|
---
|
|
|
|
## Prerequisites
|
|
|
|
- **Nim** (1.6+) — for building the bootstrap compiler
|
|
- **C compiler** (`gcc`, `clang`, or `cc`) — for the C backend
|
|
- **Make**
|
|
|
|
On Debian/Ubuntu:
|
|
```bash
|
|
sudo apt-get install nim gcc make
|
|
```
|
|
|
|
On macOS:
|
|
```bash
|
|
brew install nim gcc make
|
|
```
|
|
|
|
---
|
|
|
|
## Building the Compiler
|
|
|
|
```bash
|
|
# Release build
|
|
make build
|
|
|
|
# Development build (no optimizations, faster compile)
|
|
make dev
|
|
```
|
|
|
|
The output is a single binary: `buxc`.
|
|
|
|
---
|
|
|
|
## Creating a Project
|
|
|
|
```bash
|
|
# Create a new package in a new directory
|
|
./buxc new myproject
|
|
cd myproject
|
|
```
|
|
|
|
This generates:
|
|
```
|
|
myproject/
|
|
├── bux.toml
|
|
└── src/
|
|
└── Main.bux
|
|
```
|
|
|
|
### bux.toml
|
|
|
|
```toml
|
|
[Package]
|
|
Name = "myproject"
|
|
Version = "0.1.0"
|
|
Type = "bin"
|
|
|
|
[Build]
|
|
Output = "Bin"
|
|
```
|
|
|
|
---
|
|
|
|
## Building and Running
|
|
|
|
```bash
|
|
# Type-check without building
|
|
./buxc check
|
|
|
|
# Build
|
|
./buxc build
|
|
|
|
# Build and run
|
|
./buxc run
|
|
|
|
# Clean build artifacts
|
|
./buxc clean
|
|
```
|
|
|
|
Build output goes to `build/` by default.
|
|
|

|
|
|
## Running Tests
|
|
|
|
### Compiler Tests
|
|
```bash
|
|
make test
|
|
```
|
|
|
|
This runs:
|
|
- Lexer unit tests
|
|
- Parser unit tests
|
|
- Semantic analysis unit tests
|
|
- HIR lowering unit tests
|
|
- Integration tests (`buxc new`, `buxc --version`)
|
|
|
|
### Example Programs
|
|
```bash
|
|
make test-examples
|
|
```
|
|
|
|
Compiles and runs all programs in `examples/`.
|
|
|
|
### Individual Example
|
|
```bash
|
|
mkdir -p examples_pkg/hello/src
|
|
cp examples/hello.bux examples_pkg/hello/src/Main.bux
|
|
# Create bux.toml manually or use `buxc new`
|
|
cd examples_pkg/hello && ../../buxc run
|
|
```
|
|

## Debugging
|
|
|
|
### Verbose Output
|
|
```bash
|
|
./buxc build -v
|
|
```
|
|
|
|
### Inspecting Generated C
|
|
```bash
|
|
./buxc build
|
|
cat build/main.c
|
|
```
|
|
|
|
### Common Errors
|
|
|
|
| Error | Cause | Fix |
|
|
|-------|-------|-----|
|
|
| `stdlib directory not found` | `buxc` can't find `stdlib/` | Run from project root or set correct path |
|
|
| `duplicate symbol 'bux_alloc'` | Multiple stdlib modules declare same extern | Only declare in one module |
|
|
| `C compilation failed` | Generated C has errors | Check `build/main.c` for issues |
|
|
|
|

|
|
|
|
## Adding a New Example
|
|
|
|
1. Create `examples/myexample.bux`
|
|
2. Add `myexample` to `EXAMPLES` in `Makefile`
|
|
3. Run `make test-examples`
|
|
|

|
|
|
|
## Development Workflow
|
|
|
|
```bash
|
|
# After making changes to the compiler:
|
|
make build
|
|
make test
|
|
|
|
# If tests pass, run examples:
|
|
make test-examples
|
|
```
