Craft App Libraries

This repo contains libraries used by the various Craft Apps. It's a Rust monorepo workspace, and the libraries can be included by any Craft Apps that need them.

In the future this may grow to include non-Rust library code.

If any libraries grow beyond Craft App usage, eg. RAW format support, they may be promoted out and into their own libraries for the broader ecosystem to take advantage of.

Layout

A Cargo workspace (edition 2024, resolver 3). Each library is a crate under crates/<name>, named craft-<name>, with version, edition, license and repository inherited from the workspace (license.workspace = true, and so on) and [lints] workspace = true. Register each crate in [workspace.dependencies] in the root Cargo.toml.

Apps depend on a crate by git:

craft-<name> = { git = "https://github.com/storytold/craft-libs", rev = "<commit>" }

Libraries

• craft-atomic: Crash-safe atomic file writing and replacement with same-directory staging, directory fsync, Apple F_FULLFSYNC fallback, transient lock backoff, and fault injection for the Craft suite.

• craft-cms: pure-Rust ICC v2/v4 colour management: profile parsing and writing, transforms, rendering intents, black point compensation, soft proofing, gamut checks, 3D LUTs and built-in profiles (sRGB, Display P3, synthetic coated CMYK and others).

• craft-print: PDF submission to CUPS and Windows, printer discovery, duplex/copies/colour and driver preferences. PDF generation stays in each app.

• craft-quit: native macOS quit, egui close handling and an optional app menu. Unsaved-document decisions and save prompts stay in each app.

• craft-settings: config.toml settings storage for every app: platform folders, portable mode and overrides, atomic saves while running, backup, damaged-file recovery and schema migrations. Policy in docs/settings-storage.md.

• craft-ui: SVG catalogs, icon buttons, tabs, pane controls, transactional docking, print settings and theme helpers for egui frontends; assets, themes, localization and command handling stay in each app. Requires Rust 1.95 or later.

• Shared UI component audit: source inventory, extraction priorities and compatibility boundaries across the Craft suite.

• Theme infrastructure: eight-app comparison and the small shared widget-state styling boundary.

• Panel docking: validated panel moves, floating groups, workspace adapters and an optional egui docking surface.
