Project Vision & Core Principles** + +The goal is to create `rust-testscript`, a crate for testing command-line tools using filesystem-based script files, mirroring the functionality and developer experience of Go's `rogpeppe/go-internal/testscript`. + + * **Idiomatic Rust:** The library must feel natural to Rust developers. This means using `Result` for error handling, leveraging iterators, employing the builder pattern for configuration, and using traits for extensibility. + * **Modularity:** Components like the parser, environment manager, and command executor should be distinct and testable in isolation. + * **Extensibility:** Users must be able to easily define their own custom commands and conditions, just like in the Go version. + * **Minimal Dependencies:** We will rely on well-vetted, popular crates where necessary (e.g., for temp files, command execution) but avoid unnecessary bloat. + +### **2. High-Level Architecture** + +The library will consist of several key components that work together: + +1. **Test Runner:** The main entry point for the user. It discovers test script files and orchestrates their execution. +2. **Script Parser:** Responsible for parsing the `.txtar` format into a structured representation of commands and files. +3. **Execution Environment:** Manages the temporary, isolated directory for each test script run, including file setup and environment variables. +4. **Command Engine:** A dispatcher that interprets and executes parsed commands (e.g., `exec`, `cmp`, `stdout`) against the execution environment. +5. **Configuration (`RunParams`):** A builder struct that allows users to customize the test run, such as by adding custom commands or setup logic. + +----- + +### **3. Phase 1: The Core Engine (MVP)** + +This phase focuses on building the non-extensible core functionality. The goal is to successfully parse and run a basic test script with built-in commands. + +#### **Task 3.1: Project Scaffolding** + + * Initialize a new Rust library crate: `cargo new --lib rust-testscript`. + * Set up the initial `Cargo.toml` with metadata (authors, license, description). + * Add initial dependencies: + * `anyhow` for simple, flexible error handling. + * `thiserror` for creating custom, structured error types. + * `tempfile` for creating isolated temporary directories for test runs. + * `walkdir` for discovering test script files. + +#### **Task 3.2: Implement the `txtar` Parser** + + * Create a new module: `mod parser;`. + * **Data Structures:** Define structs to represent the parsed script. + ```rust + // Represents a single file block in the archive + pub struct TxtarFile { + pub name: String, + pub contents: Vec, + } + + // Represents the parsed script and its associated files + pub struct Script { + pub commands: Vec, + pub files: Vec, + } + + // Represents a single command line in the script + pub struct Command { + pub name: String, + pub args: Vec, + pub line_num: usize, + } + ``` + * **Parsing Logic:** Implement a function `parser::parse(content: &str) -> Result
