castletool

PyPI Version Python Versions Downloads License Build Status

Images, vector graphics, videos, audio. You name it, castletool (probably) supports it.

Castletool is a custom tool that lets you import things to castle more easily.

Installation

pip install castletool

Requires Python and the Castle CLI

Usage

Run castletool inside a folder containing your Castle deck(s). You may also use castletool --cli for the legacy interface. castletool --version (or -v) prints the installed version.

Capabilities

  • Add image — bitmap images, animated GIF/WEBP/APNG, video (with sound), and SVG are all supported.
  • Add MIDI — converts a MIDI file into a Castle Music component.
  • Add Font — renders a font's characters as vectors.
  • Edit Background Color — sets the card's background color.
  • Upload Deck — runs castle save-deck on the current deck.

Add Font: Basic

Choose from preset unicode ranges and select as many as you want:

  • Standard (0-255, excluding control characters)
  • ASCII
  • Alphanumeric
  • Numeric
  • Currency Symbols
  • Greek Characters
  • Fraction Symbols
  • Arrows
  • Mathematical Operators
  • Miscellaneous Technical
  • Box Drawing
  • Block Elements
  • Dingbats
  • Braille Patterns
  • Musical Symbols

Add Font: Advanced

Choose all characters/codepoints yourself:

  • Plain characters are typed as-is: 0123456789ABCDEF.
  • A specific codepoint is written U+XXXX (hex): U+03A9 is Ω.
  • Separate every codepoint with a space: Something like U+03A9U+0021 is invalid.
  • Any character or codepoint used twice is rejected.

Loading from a file uses the same rules, plus -- starts a comment that runs to the end of the line.
