piccali-cli-0.4.0 is not a library.

piccali-cli

piccali-cli turns your Gherkin .feature files into living documentation — either as a static JSON/HTML artifact or as a locally-served interactive viewer you can open in any browser.

Features

JSON output — Export your full feature tree as structured JSON, ready to integrate with any pipeline or documentation system
HTML output — Generate a self-contained static site (React SPA + data files) you can host anywhere, no server required
Interactive viewer — Serve the documentation locally with a single command; your browser becomes a fully functional feature explorer
Folder-aware tree — Mirrors your feature file hierarchy in the sidebar, with collapsible folders and scenario count badges
Feature pages — Browse individual feature files with keyword, description, tags, background steps, rules, and scenarios
Scenario Outlines — Preview variable substitution row-by-row directly in the UI; selected rows highlight their resolved step text live
Full-text search — Search across feature names, scenario names, step text, and tags from the header bar; supports @tag prefix syntax
Tag hyperlinks — Map tag prefixes to external URLs (e.g. Jira, Linear) so every tag becomes a clickable link to your issue tracker
Keyboard-first — Trigger global search with Ctrl+K / Cmd+K, navigate results with arrow keys, and confirm with Enter

Getting Started

Installation

From npm (recommended):

npx piccali-cli

From crates.io:

cargo install piccali-cli

Build from source:

git clone https://github.com/Odonno/piccali-cli
cd piccali-cli
cargo build --release
# binary is at ./target/release/piccali-cli

Prerequisites: Rust (edition 2024), and bun (required to build the frontend template).

Serve the interactive viewer

Run from any directory containing .feature files:

piccali-cli

Opens the viewer at http://localhost:3000. Change the port with -p:

piccali-cli -p 8080

Export to HTML (static site)

piccali-cli --formatter html --output ./docs/features

The output directory contains the full React SPA and two data files (data.json, metadata.json). Drop it on any static host (GitHub Pages, Netlify, S3, etc.).

Export to JSON

# Write to a file
piccali-cli --formatter json --output features.json

# Print to stdout
piccali-cli --formatter json --dry-run

Hyperlink tags to an issue tracker

Use --tag-prefix and --tag-url-template (repeatable) to turn tags like @feat:ABC-123 into clickable links:

piccali-cli \
  --tag-prefix "feat:" \
  --tag-url-template "https://linear.app/my-team/issue/{id}"

The {id} placeholder is replaced by the part of the tag after the prefix.

Custom glob for feature files

By default, piccali-cli discovers all **/*.feature files under the current directory. Override with -i:

piccali-cli -i "src/tests/**/*.feature" --formatter json --dry-run

CLI Reference

Usage: piccali-cli [OPTIONS]

Options:
  -i, --input <GLOB>               Glob pattern for .feature files [default: **/*.feature]
  -f, --formatter <FORMATTER>      Output format: json | html | markdown
  -o, --output <PATH>              Output file or directory (conflicts with --dry-run)
      --dry-run                    Print output to stdout instead of writing a file
  -t, --title <TITLE>              Document title [default: "Cucumber docs"]
  -p, --port <PORT>                Port for the built-in web server [default: 3000]
      --tag-prefix <PREFIX>        Tag prefix to match (repeatable, pairs with --tag-url-template)
      --tag-url-template <URL>     URL template for tag links; use {id} as placeholder (repeatable)
  -h, --help                       Print help
