ReShiki 0.5.0

ReShiki 0.5.0 adds native Windows clipboard and printing support, editable drawings in Microsoft Office, and more chemistry and image processing in Rust.

  • Editable Office drawings on Windows: copy from ReShiki into desktop Word, PowerPoint or Excel, double-click to edit, and press Ctrl+S to update the embedded drawing. Transparent vector previews stay sharp when resized. In Excel, set the object’s fill to No fill to show worksheet cells through it.
  • Windows clipboard and printing: native Copy/Paste preserves editable drawings, Copy Image offers static image formats, and the Windows print dialog supports page ranges and printer preferences. The installer registers ReShiki as the embedded drawing editor.
  • Windows rendering: direct software rendering avoids expensive GPU emulation on virtual machines and remote desktops. Clipboard, printing and process support are built into the application without a .NET runtime or extra helper.
  • Rust chemistry and file handling: binary CDX conversion, molecular formulas and masses, valence checks, hydrogen counts, and bounded ring perception now run in Rust. Ring calculations retain a checked RDKit fallback when agreement cannot be established.
  • Images: embedded raster normalization runs in Rust, preserving orientation, reflection and transparency. Pillow is no longer installed in the production chemistry environment.
  • Documentation: the Windows guide covers installation, native printing and verified Word, PowerPoint and Excel editing workflows.

Install uv before first launch. Python and RDKit are still required and are set up automatically. Downloads cover Apple Silicon macOS, Windows x64/ARM64, and Linux x64/ARM64. macOS packages are signed and notarized; Windows and Linux packages remain unsigned.

Office double-click editing requires desktop Office on Windows. Keep a separate .reshiki original when sharing editable drawings with a Mac. See the Windows notes for platform limits and the architecture notes for the Rust migration’s verification scope.
