754f4d70e0 Print on Windows in-process, without PowerShell
craft-print's Windows backend ran an embedded PowerShell script for the printer list and every
job. Under App Control for Business or AppLocker script enforcement that script runs in
Constrained Language Mode and every job fails (storytold/pdfcraft#1107). The backend now runs
in this process and starts no program:

- Printers come from EnumPrinters and the default from GetDefaultPrinter; Printer::two_sided
  from each driver's PrintCapabilities. The list is sorted, each name once.
- A job is drawn as vectors by the in-box Windows.Data.Pdf with Direct2D into the XPS print
  API (winprint). Copies, collation, duplex (left out for duplex: None), colour, orientation
  and the driver's own paper option go in a PrintTicket the driver validates; a ticket the
  driver changed (paper, orientation, scaling) is refused before anything is sent. The driver
  paper named like the standard size is preferred (pdfcraft#599).
- A job has one ticket, so one paper shape. A small lenient reader (sheets.rs) reads the
  print-ready PDF's sheets and, when needed, appends an incremental update: /Rotate for sheets
  of the other orientation, and for Scaling::ShrinkToFit a reframe onto the driver's matching
  or default paper (shrunk inside its widest hardware margin, never enlarged, centred).
  Exact size refuses mixed paper sizes and paper the driver lacks.
- command_preview describes the in-process job on Windows ("xps-print", key=value options).
- windows_print.ps1 and the PowerShell helpers are gone. open_printer_preferences (rundll32)
  and the CUPS path are unchanged, as is the public API.

The end-to-end test puts a paused Generic / Text Only printer on LPT1: (no port to remove
afterwards; a paused FILE: queue never takes the job) and checks a mixed-orientation exact job
and a shrink-to-fit job each land as one job with all sheets. The reader is tested on every
platform with classic and compressed cross-references and thousands of truncated and corrupted
files. Windows-only dependencies: winprint =0.2.1 (default features off), winsafe 0.0.29,
roxmltree 0.20, miniz_oxide 0.8.

Ported from PdfCraft's native printing branch (pdfcraft#1132), which carries #599's approach.

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

  • craft-ui: SVG catalogs, icon buttons, tabs, pane controls, transactional docking 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.
