codeglass 0.1.2

Code intelligence engine — extract symbols, references, and structure from codebases using tree-sitter

codeglass

Code intelligence engine — extract symbols, references, import graphs, call graphs, type hierarchies, and structural outlines from codebases using tree-sitter.

Language-agnostic core with per-language plugins. 7 languages supported out of the box.

Quick Start

pip install codeglass

from pylens import CodeLens

lens = CodeLens()

# Get all symbols from a file
outline = lens.get_symbols("src/main.py")
for sym in outline.symbols:
    print(f"{sym.kind:10} {sym.name:30} line {sym.line}")

# Get the import graph of a project
graph = lens.get_import_graph("src/")
print(f"{graph.stats.total_files} files, {graph.stats.total_imports} imports")

# Find what a function calls
calls = lens.get_call_graph("handle_request", "src/server.py", 42)
for callee in calls.callees:
    print(f"  → {callee.name} (line {callee.resolved_line})")

# Get the class hierarchy
hierarchy = lens.get_type_hierarchy("src/")
for name, node in hierarchy.types.items():
    if node.subclasses:
        print(f"{name} → {', '.join(node.subclasses)}")

Features

Operation	Description	Deterministic
get_symbols	Extract functions, classes, methods with signatures and docstrings	✅
get_references	Find all usages of a symbol across a codebase	⚠️ cross-file: best-effort
get_outline	Recursive directory tree with per-file symbol summaries	✅
get_import_graph	Full import graph: imports, imported_by, stats, orphans	✅
get_call_graph	Callees — what does this function call?	✅
get_test_coverage	Find test files and match test functions to source symbols	⚠️ file matching: heuristic
get_type_hierarchy	Class inheritance graph with bases, subclasses, abstract detection	✅
find_similar	Find structurally similar functions via AST fingerprinting	✅

Supported Languages

Python, JavaScript, TypeScript, Go, Rust, C/C++, Ruby

Adding a new language takes ~30 lines of tree-sitter queries.
