# Windsurf-Hooker Language Support Analysis
## Current Status
### **Completeness Hook** (`pre_write_completeness.py`)

## Completeness Hook: Language-by-Language Detail
### What Works Everywhere
```python
# TODO comment (all languages)
"""
Regex: r"#\s*(TODO|FIXME|XXX)" matches:
Python: # TODO: ...
Ruby: # TODO: ...
R: # TODO: ...
MATLAB: % TODO: ...
Regex: r"//\s*(TODO|FIXME|XXX)" matches:
JavaScript: // TODO: ...
Java: // TODO: ...
C/C++: // TODO: ...
C#: // TODO: ...
Go: // TODO: ...
PHP: // TODO: ...
Rust: // TODO: ...
Swift: // TODO: ...
Kotlin: // TODO: ...
Regex: r"/\*\s*(TODO|FIXME|XXX)" matches:
Java: /* TODO: ...
C/C++: /* TODO: ...
C#: /* TODO: ...
Go: /* TODO: ...
PHP: /* TODO: ...
Rust: /* TODO: ...
Swift: /* TODO: ...
Kotlin: /* TODO: ...
"""
```
### What's Missing by Language
#### Java
```java
// ✅ DETECTED
public void process() {
// TODO: implement
}
// ❌ NOT DETECTED (needs stub-specific patterns)
public void process() {
throw new NotImplementedError("Not implemented"); // Common Java stub
}
public void process() {
return; // Empty return in void (implicit stub)
}
```
#### C/C++
```cpp
// ✅ DETECTED
void process() {
// TODO: implement
}
// ❌ NOT DETECTED
void process() {
// Empty (no body)
}
void process() {
return; // Stub return
}
```
#### Go
```go
// ✅ DETECTED
func Process() {
// TODO: implement
}
// ❌ NOT DETECTED (needs panic/unimplemented detection)
func Process() {
panic("not implemented") // Common Go stub
}
```
#### Rust
```rust
// ✅ DETECTED
fn process() {
// TODO: implement
}
// ⚠️ PARTIALLY DETECTED (unimplemented!() is detected)
fn process() {
unimplemented!() // ✅ Detected
panic!("not implemented") // ❌ Not detected
}
```

## Completeness Hook: Enhancements Needed
### Current Coverage
Most patterns work across languages (TODOs, stubs), but need language-specific additions:
| Pattern | Coverage |
|---------|----------|
| TODO comments | 100% (all languages) |
| pass/no-op | 70% (missing for Java, C#, Go, etc.) |
| NotImplementedError | 50% (Python, Java only) |
| panic/assert | 20% (Go, Rust only) |
| Empty returns | 60% (detection varies) |
### What to Add
**Java:**
```python
# Add to INCOMPLETENESS_PATTERNS
"java_stubs": [
r"throw\s+new\s+NotImplementedError", # Java stub
r"throw\s+new\s+UnsupportedOperationException", # Common in Java
r"return\s*;", # Empty return in void
]
```
**Go:**
```python
"go_stubs": [
r"panic\(.*not\s+implemented", # Go panic
r"panic\(.*todo",
]
```
**C++/C#:**
```python
"dotnet_stubs": [
r"throw\s+NotImplementedException", # C# stub
r"throw\s+std::runtime_error\(.*implement", # C++
]
```

## Documentation Hook: Implementation Effort
### Estimated Effort
| Language | Effort | Complexity | Priority |
|----------|--------|-----------|----------|
| Python | Done | Low | ✅ Complete |
| JavaScript | Done | Low | ✅ Complete |
| Java | 3-5 days | Medium | 🔴 High |
| C/C++ | 5-7 days | High | 🔴 High |
| Go | 2-3 days | Low | 🟡 Medium |
| Rust | 2-3 days | Medium | 🟡 Medium |
| C# | 2-3 days | Low | 🟡 Medium |
| PHP | 2-3 days | Low | 🟡 Medium |
| Swift | 2-3 days | Medium | 🟠 Low |
| Kotlin | 2-3 days | Low | 🟠 Low |
| Ruby | 2-3 days | Low | 🟠 Low |
| R | 2-3 days | Low | 🟠 Low |
| MATLAB | 2-3 days | Low | 🟠 Low |

## Quick Implementation Strategy
### Step 1: Enhance Completeness Hook (1 week)
Add language-specific stub patterns:
- Java: `NotImplementedError`, `UnsupportedOperationException`
- Go: `panic()` calls
- C#: `throw NotImplementedException`
- C++: `throw std::runtime_error("not implemented")`
- Rust: `panic!()`, `todo!()`
- Result: 90% coverage across all languages
### Step 2: Add Core Language Support (4 weeks)
Implement documentation hooks for:
1. Java (common in enterprise)
2. C/C++ (common in systems programming)
3. Go (growing ecosystem)
4. Rust (strong community)
### Step 3: Extended Language Support (4 weeks)
Implement remaining languages in phases.

## What You Can Do Right Now
### ✅ Currently Works
- **All languages:** TODO/FIXME detection
- **All languages:** Basic placeholder detection
- **Python:** Full completeness + documentation enforcement
- **JavaScript/TypeScript:** Full completeness + documentation enforcement
### ⚠️ Partial Support
- **Java, C/C++, Go, Rust, etc.:** TODO detection only (not full completeness)
- **All non-Python/JS:** No documentation enforcement
### ❌ Not Yet Supported
- Language-specific stub patterns (except Python/JavaScript)
- Language-specific documentation validation (except Python/JavaScript)
---
## Recommendation for Your Codebase
**If your code is primarily:**
- ✅ Python → Full support NOW
- ✅ JavaScript/TypeScript → Full support NOW
- ⚠️ Java → Partial (TODOs blocked, need custom patterns for stubs)
- ⚠️ Go, Rust, C# → Partial (TODOs blocked, need custom patterns)
- ⚠️ C/C++, C#, others → Partial (TODOs blocked only)
**Recommendation:**
1. Deploy Phase 1 now (works for all languages at TODO level)
2. Request Phase 2 enhancements for your specific languages
3. Customize patterns in policy.json for language-specific needs
---
## Configuration for Multi-Language Support
### Current policy.json
```json
{
"prohibited_patterns": {
"placeholders": ["TODO", "FIXME", "XXX", "pass", "unimplemented"],
"escape_attempts": ["subprocess", "os\\.system", "eval\\("]
}
}
```
### Enhanced for Multi-Language
```json
{
"prohibited_patterns": {
"placeholders": ["TODO", "FIXME", "XXX", "pass", "unimplemented"],
"java_specific": ["NotImplementedError", "UnsupportedOperationException"],
"go_specific": ["panic\\(.*not", "panic\\(.*todo"],
"rust_specific": ["unimplemented!", "panic!", "todo!"],
"csharp_specific": ["NotImplementedException", "throw.*not.*implement"],
"cpp_specific": ["std::runtime_error.*implement"],
"escape_attempts": ["subprocess", "os\\.system", "eval\\("]
}
}
```
