# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Commands
|
||||
|
||||
```sh
|
||||
cargo build # build the project
|
||||
cargo run -- <cmd> # run a subcommand (e.g. cargo run -- init)
|
||||
cargo test # run all tests
|
||||
cargo test <name> # run a single test by name
|
||||
cargo clippy # lint
|
||||
```
|
||||
|
||||
## What This Project Is
|
||||
|
||||
`tour` is a CLI tool for creating and navigating code tutorials as a series of snapshots. Authors create tours by committing file snapshots with explanations; readers step through them with `next`/`prev`.
|
||||
|
||||
**Author workflow:** `tour init` → `tour add <files>` → `tour commit -m <msg>` (repeat) → `tour end -m <msg>`
|
||||
|
||||
**Reader workflow:** `tour start` → `tour next [n]` / `tour prev [n]` / `tour step <n>` / `tour reset`
|
||||
|
||||
## Architecture
|
||||
|
||||
Entry point is `main.rs`, which uses clap's derive macro to parse subcommands and dispatch to per-command modules.
|
||||
|
||||
**On-disk format** (stored in `.tour/` in the project being toured):
|
||||
- `.tour/steps/<N>/` — one numbered directory per step (each step is a complete file snapshot)
|
||||
- `.tour/steps/<N>/message` — the commit message for that step
|
||||
- `.tour/session` — tracks current reader position as `STEP=<n>`
|
||||
- `.tour/staged` — list of files staged for the next commit
|
||||
- `.tour/info` — tour metadata (author, description, language, dates)
|
||||
- `.tour/removed` — list of files marked for removal in the next commit
|
||||
- `.tour/ended` — marker file indicating the tour is finalized
|
||||
|
||||
**Module layout:**
|
||||
- `init.rs` — creates `.tour/` structure, collects tour metadata, updates `.gitignore`
|
||||
- `add.rs` — stages files for the next commit; `get_staged()` reads the staged file list
|
||||
- `unstage.rs` — removes files from staging
|
||||
- `commit.rs` — commits staged files as a new step with carry-forward from previous step; only clears staging when staging was used
|
||||
- `rm.rs` — marks files for removal in the next commit (skipped during carry-forward)
|
||||
- `end.rs` — finalizes the tour (writes `.tour/ended` marker)
|
||||
- `step.rs` — navigation: `next`, `prev`, `step_n`; handles file replacement, diff display, binary detection
|
||||
- `reset.rs` — resets tour session and removes tracked files from working directory
|
||||
- `status.rs` — shows current step position and staged files
|
||||
- `list.rs` — lists all steps with their messages
|
||||
- `info.rs` — tour metadata (author, description, language, dates)
|
||||
- `utils.rs` — shared helpers: `require_tour`, `get_current_step`, `get_tour_step`, `copy_tree`, path validation
|
||||
- `error.rs` — unified `TourError` enum with `Display` impl for user-facing messages; includes `CorruptedTour` for integrity checks
|
||||
|
||||
**Key design decisions:**
|
||||
- Each step is a **complete snapshot** — `commit.rs` carries forward files from the previous step before overlaying new ones
|
||||
- `TourError` is the unified error type across all modules, with `From<io::Error>` for automatic conversion
|
||||
- `main()` catches errors and prints them with `Display` format (not `Debug`) for user-friendly messages
|
||||
- Constants `TOUR_DIR` and `SESSION_PATH` are defined in `main.rs` and imported via `crate::`
|
||||
|
||||
**Testing:** Integration tests in `tests/integration.rs` use `tempfile` crate to create isolated tour directories and test via `Command`-based process spawning.

# Goals
|
||||
# tour
|
||||
|
||||
The purpose of this command will be to walk through code tutorials
|
||||
A CLI tool for creating and navigating code tutorials as a series of file snapshots.
|
||||
|
||||
It will be essentially the same as git, however without branches.
|
||||
## Install
|
||||
|
||||
Through a series of commits, you can walk through code changes and see what has changed (like git diff)
|
||||
|
||||
It will work as such
|
||||
|
||||
````
|
||||
```sh
|
||||
# The format of this is:
|
||||
cargo install --path .
|
||||
```
|
||||
|
||||
command args
|
||||
# ->
|
||||
# output
|
||||
# output line 2
|
||||
## Quick Start
|
||||
|
||||
# CREATING A TOUR
|
||||
tour init -m "After running *cargo init* we get our template"
|
||||
### Creating a tour
|
||||
|
||||
```sh
|
||||
# Initialize a new tour in the current directory
|
||||
tour init
|
||||
|
||||
# Stage and commit files as steps
|
||||
tour add src/main.rs Cargo.toml
|
||||
tour commit -m "After running cargo init we get our template"
|
||||
|
||||
# Or commit with inline file arguments
|
||||
tour commit src/lib.rs -m "In lib.rs we add some functions"
|
||||
tour commit src/main.rs -m "We import our newly made function from lib.rs"
|
||||
tour end -m "Now your tour is complete and you can use rust modules!"
|
||||
|
||||
tour commit src/main.rs -m "We import our newly made function from lib.rs"
|
||||
|
||||
# Finalize the tour
|
||||
tour end -m "Now your tour is complete and you can use rust modules!"
|
||||
```
|
||||
|
||||
### Taking a tour
|
||||
|
||||
```sh
|
||||
tour start
|
||||
# ->
|
||||
# New files:
|
||||
# ./cargo.lock

# ./cargo.toml

||||
# new: src/main.rs

||||

||||
# After running *cargo init* we get our template
|
||||
# Step 1/3: After running cargo init we get our template

||||

|
||||
|
||||

|
||||

|
||||

|
||||
# new: src/lib.rs
|
||||
# modified: src/main.rs
|
||||
# + use lib::my_function;
|
||||
#
|
||||
# Step 3/3: We import our newly made function from lib.rs
|
||||
|
||||
# Changes:
|
||||
# src/main.rs

||||
|
||||
# Explanation
|

# We import our newly made function from lib.rs

|
||||
# ->
|
||||
# Tutorial Finished
|
||||
# Explanation
|
||||
# Now your tour is complete and you can use rust modules!
|
||||
|
||||
# EXTRAS:
|
||||
tour author -> Add information about the author if there are questions
|
||||
tour step 1 # jump to any step by number
|
||||
```
|
||||
````
|
||||
|
||||
## Commands
|
||||
|
||||
### Author workflow
|
||||
|
||||
| Command | Description |
|
||||
|---------|-------------|
|
||||
| `tour init` | Set up a new tour in the current directory |
|
||||
| `tour add <files...>` | Stage files for the next commit |
|
||||
| `tour unstage <files...>` | Remove files from staging |
|
||||
| `tour commit -m <msg>` | Commit staged files as a new step |
|
||||
| `tour commit <files...> -m <msg>` | Stage and commit files in one step |
|
||||
| `tour end -m <msg>` | Finalize the tour |
|
||||
|
||||
### Reader workflow
|
||||
|
||||
| Command | Description |
|
||||
|---------|-------------|
|
||||
| `tour start` | Load the first step |
|
||||
| `tour next [n]` | Advance n steps (default 1) |
|
||||
| `tour prev [n]` | Go back n steps (default 1) |
|
||||
| `tour step <n>` | Jump to step n |
|
||||
|
||||
### Other
|
||||
|
||||
| Command | Description |
|
||||
|---------|-------------|
|
||||
| `tour info` | Show tour metadata |
|
||||
| `tour status` | Show current step and staged files |
|
||||
| `tour list` | List all steps with messages |
|
||||
| `tour help` | Show help message |
|
||||
|
||||
## How it works
|
||||
|
||||
Each step is stored as a complete file snapshot in `.tour/steps/<N>/`. When navigating between steps, `tour` replaces tracked files in your working directory and shows a diff of what changed — new files, modified files (with line-level diffs), and deleted files.
|
||||
|
||||
The `.tour/` directory contains:
|
||||
- `steps/` — numbered directories, each holding the full file state for that step plus a `message` file
|
||||
- `session` — tracks the reader's current position
|
||||
- `info` — tour metadata (author, description, language, dates)
|
||||
- `staged` — files staged for the next commit
|
||||
- `ended` — marker indicating the tour is finalized
