currust - a cursor converter

A portmanteau of "cursor" and "Rust".

A tool written in Rust to convert cursors between Windows and Linux. Specifically, converting from the CUR/ANI format to the Xcursor format (plus some other features).

There are quite a few CLI tools that already exist for this purpose. You can see a comparison in COMPARISONS.md that I've tried to keep neutral if you need help deciding.

Installation

There are currently two supported methods of installation:

• download the binaries on the releases page (recommended)
• build from crates with cargo install currust (requires cargo)

Usage

The intended use-case of this tool is to convert a Windows cursor theme to Linux. A cursor theme is a directory that contains some cursors, along with an installer file that uses the INF format.

You can convert a cursor theme as such:

./currust ./my-cursor-theme

This converts the theme and writes the produced X11 theme (which is a directory) in the current directory. Add the --out (or -o for short) argument to place it in the specified path.

./currust ./my-cursor-theme -o ./please/go/here/instead

Cursor themes on Windows can be scaled by Windows itself. Unfortunately, this feature doesn't exist on most Linux distributions, so Xcursor themes have to include their own size variations.

The --scale-to argument is available to provide some scale factors, along with --scale-with to provide a scaling algorithm to use (default: Lanczos3).

Note that this increases the size of the resulting cursor theme.

./currust ./my-cursor-theme --scale-to 1.5 2 3 --scale-with mitchell

Goals

All the baseline goals I had for this project are complete, so this is more akin to a "planned/future features" section. Note that not everything here may be added.

• Publish or otherwise for usage with cargo and package managers
• Conversion from X11 cursors to Windows cursors (i.e, the other way around)
• [SVG cursor themes][1] for KDE Plasma
• hyprcursor (cursor format for hyprland) support
