# Micropub CLI Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Build an ultra-compliant Micropub CLI in Rust with CLI-managed drafts, automatic media uploads, multi-site OAuth support, and full W3C spec compliance.

**Architecture:** Modular design with separate auth, draft, client, media, and config modules. CLI commands built with clap, async HTTP with reqwest/tokio, XDG-compliant storage. TDD throughout with unit, integration, and compliance tests.

**Tech Stack:** Rust 2021, clap 4, reqwest, tokio, serde, oauth2, scraper, anyhow, chrono

---

## Task 1: Project Setup & Dependencies

**Files:**
- Modify: `Cargo.toml`
- Create: `src/lib.rs`
- Modify: `src/main.rs`
- Create: `.gitignore`

**Step 1: Fix Cargo.toml edition and add dependencies**

Edit `Cargo.toml`:

```toml
[package]
name = "micropub"
version = "0.1.0"
edition = "2021"

[dependencies]
clap = { version = "4", features = ["derive"] }
reqwest = { version = "0.11", features = ["json", "multipart"] }
tokio = { version = "1", features = ["full"] }
serde = { version = "1", features = ["derive"] }
serde_json = "1"
serde_yaml = "0.9"
url = "2"
dirs = "5"
mime_guess = "2"
oauth2 = "4"
scraper = "0.18"
anyhow = "1"
chrono = { version = "0.4", features = ["serde"] }
uuid = { version = "1", features = ["v4", "serde"] }

[dev-dependencies]
mockito = "1"
tempfile = "3"
```

**Step 2: Update .gitignore**

Add to `.gitignore`:

```
/target
Cargo.lock
*.swp
*.swo
*~
.DS_Store
```

**Step 3: Create library structure**

Create `src/lib.rs`:

```rust
// ABOUTME: Main library file for micropub CLI
// ABOUTME: Exports all public modules and types

pub mod config;
pub mod auth;
pub mod draft;
pub mod client;
pub mod media;

pub use anyhow::{Result, Error};
```

**Step 4: Update main.rs with CLI skeleton**

Edit `src/main.rs`:

```rust
// ABOUTME: Main entry point for micropub CLI
// ABOUTME: Parses commands and dispatches to appropriate handlers

use clap::{Parser, Subcommand};
use micropub::Result;

#[derive(Parser)]
#[command(name = "micropub")]
#[command(about = "Ultra-compliant Micropub CLI", long_about = None)]
struct Cli {
    #[command(subcommand)]
    command: Commands,
}

#[derive(Subcommand)]
enum Commands {
    /// Authenticate with a Micropub site
    Auth {
        /// Domain to authenticate with
        domain: String,
    },
    /// Draft management commands
    #[command(subcommand)]
    Draft(DraftCommands),
    /// Publish a draft
    Publish {
        /// Path to draft file
        draft: String,
    },
    /// Publish a backdated post
    Backdate {
        /// Path to draft file
        draft: String,
        /// Date to publish (ISO 8601 format)
        #[arg(long)]
        date: String,
    },
    /// Update an existing post
    Update {
        /// URL of post to update
        url: String,
    },
    /// Delete a post
    Delete {
        /// URL of post to delete
        url: String,
    },
    /// Undelete a post
    Undelete {
        /// URL of post to undelete
        url: String,
    },
    /// Debug connection to a profile
    Debug {
        /// Profile name to debug
        profile: String,
    },
}

#[derive(Subcommand)]
enum DraftCommands {
    /// Create a new draft
    New,
    /// Edit an existing draft
    Edit {
        /// Draft ID to edit
        draft_id: String,
    },
    /// List all drafts
    List,
    /// Show a draft's content
    Show {
        /// Draft ID to show
        draft_id: String,
    },
}

#[tokio::main]
async fn main() -> Result<()> {
    let cli = Cli::parse();

    match cli.command {
        Commands::Auth { domain } => {
            println!("Auth command: {}", domain);
            Ok(())
        }
        Commands::Draft(cmd) => {
            println!("Draft command");
            Ok(())
        }
        Commands::Publish { draft } => {
            println!("Publish command: {}", draft);
            Ok(())
        }
        Commands::Backdate { draft, date } => {
            println!("Backdate command: {} at {}", draft, date);
            Ok(())
        }
        Commands::Update { url } => {
            println!("Update command: {}", url);
            Ok(())
        }
        Commands::Delete { url } => {
            println!("Delete command: {}", url);
            Ok(())
        }
        Commands::Undelete { url } => {
            println!("Undelete command: {}", url);
            Ok(())
        }
        Commands::Debug { profile } => {
            println!("Debug command: {}", profile);
            Ok(())
        }
    }
}
```

**Step 5: Verify project builds**

Run: `cargo build`
Expected: Clean build with no errors

**Step 6: Test CLI help**

Run: `cargo run -- --help`
Expected: Shows help message with all commands

**Step 7: Commit**

```bash
git add Cargo.toml src/lib.rs src/main.rs .gitignore
git commit -m "feat: add project dependencies and CLI skeleton"
```

## Task 2: Config Module & XDG Paths

**Files:**
- Create: `src/config.rs`
- Create: `tests/config_tests.rs`

**Step 1: Write test for XDG directory resolution**

Create `tests/config_tests.rs`:

```rust
use micropub::config::{get_config_dir, get_data_dir};
use std::path::PathBuf;

#[test]
fn test_config_dir_exists() {
    let config_dir = get_config_dir().expect("Should get config dir");
    assert!(config_dir.to_str().unwrap().contains("micropub"));
}

#[test]
fn test_data_dir_exists() {
    let data_dir = get_data_dir().expect("Should get data dir");
    assert!(data_dir.to_str().unwrap().contains("micropub"));
}
```

**Step 2: Run test to verify it fails**

Run: `cargo test config_tests`
Expected: FAIL - module not found

**Step 3: Implement XDG directory helpers**

Create `src/config.rs`:

        if config_path.exists() {
            let contents = fs::read_to_string(&config_path)
                .context("Failed to read config file")?;
            let config: Config = toml::from_str(&contents)
                .context("Failed to parse config file")?;

            .context("Failed to serialize config")?;
        fs::write(&config_path, contents)
            .context("Failed to write config file")?;
        Ok(())
    }

    /// Get a profile by name

        let toml = toml::to_string(&config).unwrap();
        assert!(toml.contains("example.com"));
    }
}
```

**Step 4: Add toml dependency**

Edit `Cargo.toml` dependencies section:

```toml
toml = "0.8"
```

**Step 5: Run tests to verify they pass**

Run: `cargo test`
Expected: All tests pass

**Step 6: Commit**

```bash
git add Cargo.toml src/config.rs tests/config_tests.rs
git commit -m "feat: add config module with XDG directory support"
```

## Task 3: Draft Data Structures

**Files:**
- Create: `src/draft.rs`
- Create: `tests/draft_tests.rs`

**Step 1: Write test for draft metadata parsing**

Create `tests/draft_tests.rs`:

```rust

#[test]
fn test_parse_draft_with_frontmatter() {
    let content = r#"---
type: article
name: "Test Post"
category:

---

This is the post content.
"#;

        .expect("Should parse draft");

    assert_eq!(draft.metadata.name, Some("Test Post".to_string()));

```

**Step 2: Run test to verify it fails**

Run: `cargo test draft_tests`

## Task 4: Draft Commands Implementation

**Files:**
- Modify: `src/draft.rs`
- Modify: `src/main.rs`

**Step 1: Add draft command handlers to main.rs**

Edit `src/main.rs`, replace the Draft command handler:

```rust
Commands::Draft(cmd) => match cmd {
    DraftCommands::New => {
        micropub::draft::cmd_new().await?;
        Ok(())
    }
    DraftCommands::Edit { draft_id } => {
        micropub::draft::cmd_edit(&draft_id).await?;
        Ok(())
    }
    DraftCommands::List => {
        micropub::draft::cmd_list().await?;
        Ok(())
    }
    DraftCommands::Show { draft_id } => {
        micropub::draft::cmd_show(&draft_id).await?;
        Ok(())
    }
},
```

**Step 2: Implement draft command functions**

Add to `src/draft.rs`:

```rust
use crate::config::Config;
use std::process::Command;

/// Create a new draft and open in editor
pub async fn cmd_new() -> Result<()> {
    let id = generate_draft_id();
    let mut draft = Draft::new(id.clone());

    // Save initial draft
    let path = draft.save()?;

    // Open in editor
    let config = Config::load()?;
    let editor = config.editor
        .or_else(|| std::env::var("EDITOR").ok())
        .unwrap_or_else(|| "vim".to_string());

    Command::new(&editor)
        .arg(&path)
        .status()
        .context("Failed to open editor")?;

    println!("Draft created: {}", id);
    println!("Path: {}", path.display());

    Ok(())
}

/// Edit an existing draft
pub async fn cmd_edit(draft_id: &str) -> Result<()> {
    let path = get_drafts_dir()?.join(format!("{}.md", draft_id));

    if !path.exists() {
        anyhow::bail!("Draft not found: {}", draft_id);
    }

    let config = Config::load()?;
    let editor = config.editor
        .or_else(|| std::env::var("EDITOR").ok())
        .unwrap_or_else(|| "vim".to_string());

    Command::new(&editor)
        .arg(&path)
        .status()
        .context("Failed to open editor")?;

    Ok(())
}

/// List all drafts
pub async fn cmd_list() -> Result<()> {
    let draft_ids = Draft::list_all()?;

    if draft_ids.is_empty() {
        println!("No drafts found.");
        return Ok(());
    }

    println!("Drafts:");
    for id in draft_ids {
        match Draft::load(&id) {
            Ok(draft) => {

## Task 5: HTTP Client & Micropub Request Structures

**Files:**
- Create: `src/client.rs`
- Create: `tests/client_tests.rs`

**Step 1: Write test for micropub request serialization**

Create `tests/client_tests.rs`:

```rust

#[test]
fn test_create_request_json() {
    let mut props = serde_json::Map::new();

**Step 3: Update main.rs publish commands**

Edit `src/main.rs`, update publish handlers:

```rust
Commands::Publish { draft } => {

    Ok(())
}
```

**Step 4: Test publish command (will fail without auth)**

Run: `cargo build`
Expected: Clean build

**Step 5: Commit**

```bash
git add src/lib.rs src/publish.rs src/main.rs
git commit -m "feat: implement publish command with media upload"

## Task 11: Documentation

**Files:**
- Create: `README.md`
- Create: `docs/USAGE.md`

**Step 1: Create README**

Create `README.md`:

```markdown
# Micropub CLI

An ultra-compliant Micropub CLI for interacting with Micropub-enabled sites like micro.blog.

## Features

- ✅ Full W3C Micropub spec compliance
- ✅ CLI-managed drafts with YAML frontmatter
- ✅ Automatic media upload and URL replacement
- ✅ Multi-site support with profiles
- ✅ IndieAuth/OAuth authentication
- ✅ Create, update, delete, undelete posts
- ✅ Backdated post publishing
- ✅ XDG-compliant configuration storage

## Installation

```bash
cargo install --path .
```

## Quick Start

1. **Authenticate with your site:**
   ```bash
   micropub auth micro.blog
   ```

2. **Create a new draft:**
   ```bash
   micropub draft new
   ```

3. **List drafts:**
   ```bash
   micropub draft list
   ```

4. **Publish a draft:**
   ```bash
   micropub publish <draft-id>
   ```

See [USAGE.md](docs/USAGE.md) for detailed documentation.

## Architecture

- `config` - Configuration and XDG directory management
- `auth` - IndieAuth/OAuth authentication
- `draft` - Draft lifecycle management
- `client` - Micropub HTTP client
- `media` - Media upload and path replacement
- `publish` - Post publishing orchestration
- `operations` - Update/delete/undelete operations

## Testing

```bash
# Run all tests
cargo test

# Run with output
cargo test -- --nocapture

# Run specific test
cargo test test_name
```

## Development

Built with Rust using:
- clap - CLI argument parsing
- reqwest - HTTP client
- tokio - Async runtime
- serde - Serialization
- oauth2 - OAuth flow

## License

MIT
```

**Step 2: Create usage documentation**

Create `docs/USAGE.md`:

```markdown
# Micropub CLI Usage Guide

## Configuration

Configuration is stored in `~/.config/micropub/config.toml`:

```toml
default_profile = "micro.blog"
editor = "vim"

[profiles.micro.blog]
domain = "micro.blog"
micropub_endpoint = "https://micro.blog/micropub"
media_endpoint = "https://micro.blog/micropub/media"
```

Tokens are stored separately in `~/.local/share/micropub/tokens/`.

## Authentication

Authenticate with a Micropub site:

```bash
micropub auth micro.blog
```

This will:
1. Discover micropub and authorization endpoints
2. Prompt for an API token
3. Save the profile and token

## Draft Management

### Create a new draft

```bash
micropub draft new
```

Opens your editor with a new draft template.

### Draft format

```markdown
---
type: article
name: "My Post Title"
category:
  - rust
  - blogging
syndicate-to:
  - https://twitter.com/username
---

Post content goes here.

You can reference local images: ![photo](~/Pictures/image.jpg)
```

### List drafts

```bash
micropub draft list
```

### Edit a draft

```bash
micropub draft edit <draft-id>
```

### Show draft content

```bash
micropub draft show <draft-id>
```

## Publishing

### Publish a draft

```bash
micropub publish <draft-id>
```

This will:
1. Parse the draft
2. Upload any media files
3. Replace local paths with URLs
4. Send to micropub endpoint
5. Archive the draft with publication metadata

### Backdate a post

```bash
micropub backdate <draft-id> --date "2024-01-15T10:30:00Z"
```

## Post Management

### Delete a post

```bash
micropub delete <post-url>
```

### Undelete a post

```bash
micropub undelete <post-url>
```

### Update a post

```bash
micropub update <post-url>
```

(Coming soon)

## Multi-Site Usage

### Use a specific profile

Add `profile: mysite` to draft frontmatter, or use `--profile` flag:

```bash
micropub publish <draft-id> --profile mysite
```

## Troubleshooting

### Debug connection

```bash
micropub debug <profile-name>
```

### Check configuration

```bash
cat ~/.config/micropub/config.toml
```

### Verify token

```bash
cat ~/.local/share/micropub/tokens/<profile>.token
```
```

**Step 3: Commit documentation**

```bash
git add README.md docs/USAGE.md
git commit -m "docs: add README and usage guide"
```

## Task 12: Final Polish & Error Handling

**Files:**
- Modify: `src/client.rs`
- Modify: `src/publish.rs`
- Modify: `src/main.rs`

**Step 1: Improve error messages in client**

Edit `src/client.rs`, update error handling:

```rust
pub async fn send(&self, request: &MicropubRequest) -> Result<MicropubResponse> {
    let json = request.to_json()?;

    let response = self.http_client
        .post(&self.endpoint)
        .header(header::AUTHORIZATION, format!("Bearer {}", self.token))
        .header(header::CONTENT_TYPE, "application/json")
        .body(json)
        .send()
        .await
        .context("Failed to send request to micropub endpoint")?;

    let status = response.status();

    // Get Location header for successful creates
    let location = response.headers()
        .get(header::LOCATION)
        .and_then(|v| v.to_str().ok())
        .map(|s| s.to_string());

    let body = response.text().await?;

    if status.is_success() {
        Ok(MicropubResponse {
            url: location,
            error: None,
            error_description: None,
        })
    } else {
        // Try to parse error response
        let error_response: Result<MicropubResponse, _> = serde_json::from_str(&body);

        let error_msg = if let Ok(err) = error_response {
            format_error_message(&err.error, &err.error_description)
        } else {
            format!("HTTP {}: {}", status, body)
        };

        anyhow::bail!(error_msg);
    }
}

fn format_error_message(error: &Option<String>, description: &Option<String>) -> String {
    let error_code = error.as_deref().unwrap_or("unknown_error");
    let desc = description.as_deref().unwrap_or("No description provided");

    match error_code {
        "insufficient_scope" => {
            format!(
                "Insufficient permissions: {}\n\nRe-authenticate with: micropub auth <domain>",
                desc
            )
        }
        "invalid_request" => {
            format!("Invalid request: {}\n\nCheck your draft format and try again", desc)
        }
        "unauthorized" => {
            format!(
                "Unauthorized: {}\n\nYour token may be expired. Re-authenticate with: micropub auth <domain>",
                desc
            )
        }
        _ => {
            format!("Micropub error ({}): {}", error_code, desc)
        }
    }
}
```

**Step 2: Add verbose flag to main.rs**

Edit `src/main.rs`, add global flag:

```rust
#[derive(Parser)]
#[command(name = "micropub")]
#[command(about = "Ultra-compliant Micropub CLI", long_about = None)]
struct Cli {
    /// Enable verbose output
    #[arg(short, long, global = true)]
    verbose: bool,

    #[command(subcommand)]
    command: Commands,
}
```

**Step 3: Test error handling**

Run: `cargo build`
Expected: Clean build

**Step 4: Commit**

```bash
git add src/client.rs src/main.rs
git commit -m "feat: improve error messages and add verbose flag"
```
