# MicroHX Development State
|
||||
|
||||
**Last Updated:** 2026-03-17
|
||||
**Current Phase:** Phase 2 Complete
|
||||
**Next Phase:** Phase 3 (LSP + Tree-sitter)
|
||||

|
||||
|
||||
## Project Overview
|
||||
|
||||
MicroHX is a modern modal text editor written in Rust with:
|
||||
- Kakoune/Helix-style object-verb keybindings
|
||||
- Lua 5.4 scripting for configuration and plugins
|
||||
- Three UI modes: CLI (crossterm), TUI (ratatui), GUI (egui)
|
||||
- Built-in LSP and Tree-sitter (Phase 3+)
|
||||
- Static compilation support for portability
|
||||
|
||||

|
||||
## Test Status
|
||||
|
||||
### Library Tests: ✅ 302 PASSING
|
||||
|
||||
```
|
||||
test result: ok. 302 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out
|
||||
```
|
||||
|
||||
### Doc Tests: ⚠️ 13 FAILING (Minor)
|
||||
|
||||
Most failures are due to ropey's newline handling in examples. Core functionality is unaffected.
|
||||
|
||||
**Files with failing doc tests:**
|
||||
- `src/buffer.rs` - Line content includes newlines
|
||||
- `src/cursor.rs` - Position clamping examples
|
||||
- `src/editor.rs` - Editor API examples
|
||||
- `src/config.rs` - Lua loading examples
|
||||
- `src/keymap.rs` - Key processing examples
|
||||
- `src/undo.rs` - API examples
|
||||
- `src/fuzzy.rs` - Scoring examples
|
||||
- `src/lib.rs` - Usage examples
|
||||
|
||||
**To fix:** Update expected values in doc examples to match ropey's behavior.

|

|
||||
## Key Architecture Decisions
|
||||
|
||||
### 1. Rope-Based Buffer
|
||||
- **Library:** `ropey` v1.6
|
||||
- **Why:** O(log n) insertions/deletions, efficient for large files
|
||||
- **Note:** Line content includes trailing newlines (ropey behavior)
|
||||
|
||||
### 2. Object-Verb Keybindings
|
||||
- **Style:** Kakoune/Helix (select then act)
|
||||
- **Why:** Selection visible before action, better for multi-cursor
|
||||
- **Example:** `w` selects word, `d` deletes selection
|
||||
|
||||
### 3. Tree-Based Undo
|
||||
- **Structure:** UndoTree with branching support
|
||||
- **Why:** Supports undo + new change = new branch (like Vim)
|
||||
- **Implementation:** Nodes with parent/children relationships
|
||||
|
||||
### 4. Lua Scripting
|
||||
- **Library:** `mlua` v0.10 with Lua 5.4
|
||||
- **Feature:** Optional (`--features lua`)
|
||||
- **Why:** Familiar to Neovim users, sandboxed
|
||||
|
||||
### 5. Three UI Modes
|
||||
- **CLI:** Crossterm (default, minimal deps)
|
||||
- **TUI:** Ratatui (full terminal UI)
|
||||
- **GUI:** Egui (native window)
|
||||
- **Why:** Same core, different rendering backends
|
||||
|
||||
### 6. Static Compilation
|
||||
- **Targets:** musl-libc, zig
|
||||
- **Why:** Portability, old Linux/glibc compatibility
|
||||
- **Script:** `build-static.sh`
|
||||
|
||||

|
||||
|
||||
## Known Issues & Technical Debt
|
||||
|
||||
### High Priority
|
||||
1. **Doc tests failing** - 13 tests need example updates
|
||||
2. **Undo tree edge cases** - Single-action redo behavior
|
||||
3. **Cursor positioning** - Allow position after last char (fixed)
|
||||
|
||||
### Medium Priority
|
||||
1. **TUI mode** - Stub implementation only
|
||||
2. **GUI mode** - Stub implementation only
|
||||
3. **LSP integration** - Not started
|
||||
|
||||
### Low Priority
|
||||
1. **Performance** - No benchmarks yet
|
||||
2. **Memory usage** - Not optimized for very large files
|
||||
3. **Plugin API** - Basic structure only
|
||||

|
||||
thiserror = "2.0" # Error handling
|
||||
anyhow = "1.0" # Error handling
|
||||
tokio = "1.42" # Async runtime
|

|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Development Guidelines
|
||||
|
||||
### Code Style
|
||||
- Follow existing patterns in each module
|
||||
- Add `///` doc comments for public APIs
|
||||
- Include examples in doc comments
|
||||
- Write unit tests for new functions
|
||||
|
||||
### Testing
|
||||
```bash
|
||||
# Run all library tests
|
||||
cargo test --lib
|
||||
|
||||
# Run specific module tests
|
||||
cargo test buffer
|
||||
cargo test undo
|
||||
|
||||
# Run with output
|
||||
cargo test -- --nocapture
|
||||
|
||||
# Run doc tests
|
||||
cargo test --doc
|
||||
```
|
||||
|
||||
### Building
|
||||
```bash
|
||||
# Debug build (fast)
|
||||
cargo build
|
||||
|
||||
# Release build (optimized)
|
||||
cargo build --release
|
||||
|
||||
# Static build (portable)
|
||||
./build-static.sh
|
||||
|
||||
# Check without building
|
||||
cargo check
|
||||
|
||||
# Format code
|
||||
cargo fmt
|
||||
|
||||
# Lint
|
||||
cargo clippy -- -D warnings
|
||||
```
|
||||
|
||||
### Adding New Features
|
||||
1. Create module in `src/`
|
||||
2. Add to `src/lib.rs`
|
||||
3. Write tests in module
|
||||
4. Update `SPECIFICATION.md` if needed
|
||||
5. Update `DEVELOPMENT_STATE.md`
