Convert Claude Code TUI /export files to standalone HTML documents.

The Claude Code terminal interface's /export files have multiple uses. The motivating one for claudetxt is archiving the actual textual session for future (human) reference. This might be done before ending the session or prior to a context compaction. Having the session captured in this way might be useful to:

• Review design knowledge and intent implicit in the prompts.
• Review and analyze decisions and the Claude inputs behind them.
• Present to others for design/code review or pedagogical reasons.

claudetxt parses the syntactically-structured console /export text and generates a self-contained HTML file presenting the captured conversation in a lightly styled way, including:

• Welcome banners with box-drawn characters
• User prompts and Claude responses
• Tool invocations and their output (with error highlighting)
• Diff output with color-coded additions and deletions
• Interactive Q&A blocks and plan approvals
• Numbered and bulleted lists
• Directory tree structures

In addition to direct viewing the output is intended to be suitable for conversion to PDF via a tool such as weasyprint or simply printing to file from a browser.

The output HTML includes the full style definition, it has no external dependencies so it can be easily shared.

There is probably a more complete semantic session capture or plugin or something to do this better, but claudetxt is simple & hopefully useful. If you encounter some /export it does not parse or style well please post a ticket.

cargo build --release

The binary will be at target/release/claudetxt.

# Output to stdout
claudetxt conversation.txt

# Output to a file
claudetxt conversation.txt -o conversation.html

# Custom title and username
claudetxt export.txt -o output.html --title "Debug Session" --username "Alice"

# Replace the banner with plain text
claudetxt export.txt -o output.html --banner "Project Review"

# Replace the banner with custom HTML
claudetxt export.txt -o output.html --banner '<h1 style="color: blue;">My Project</h1>'

# Disable diff colors (useful for printing)
claudetxt export.txt -o output.html --nocolor

1. Parsing (parser.rs) — Splits the export file into typed blocks (Banner, UserPrompt, ClaudeMessage, ToolOutput) by recognizing Unicode markers (╭, ❯, ●, ⎿).
2. Transformation (transformer.rs) — Handles inline formatting, tool call detection, and structured content rendering (lists, directory trees).
3. HTML generation (html.rs) — Assembles the blocks into a complete HTML document, with special handling for diffs, Q&A interactions, and plan approvals.
4. Styling (styles.rs) — Provides embedded CSS for both screen and print output.
