panproto-project

Multi-file project assembly via schema coproduct for panproto.

Overview

Orchestrates parsing all files in a project directory into a unified project-level schema. The project schema is the coproduct (disjoint union) of per-file schemas, with cross-file edges for imports and type references.

Two-pass approach

1. Parse pass: For each file, detect language, parse via ParserRegistry, prefix vertex IDs with the file path.
2. Resolve pass: Walk import vertices, match against exports in other file schemas, emit imports edges connecting them.

Coproduct construction

The schema-level coproduct prefixes each file's vertex names with the file path. Edges within a file retain their local structure. The result is a single Schema spanning the entire project.

The coproduct is universal: any morphism out of the project schema restricts to per-file morphisms. This means per-file diffs compose into project-level diffs automatically.

Usage

use panproto_project::ProjectBuilder;

let mut builder = ProjectBuilder::new();
builder.add_directory(std::path::Path::new("./src"))?;
let project = builder.build()?;

println!("{} files, {} vertices", project.file_map.len(), project.schema.vertices.len());

Language detection

File extensions are mapped to protocols: .ts to TypeScript, .py to Python, .rs to Rust, etc. Unrecognized files fall back to the raw_file protocol (text as ordered line vertices, binary as chunk vertices).
