We use [cargo-release] to help guide the release process. It can be installed with cargo install cargo-release. You may need to install pkg-config via your package manager for this to work.

Releasing involves the following steps:

1. Determine which crates may need to be published: run cargo release changes to see which crates have been modified since their last release.

2. Determine the new versions for the crates.

   • Before 1.0, breaking changes bump the minor version number, and non-breaking changes modify the patch number.

3. Update manifest versions and release. ./resources/scripts/bump-version.sh orchestrates this process.

   • cargo release does all the heavy lifting

   # To see usage
   ./resources/scripts/bump-version.sh
   # To do the thing
   ./resources/scripts/bump-version.sh  sleipnir patch

4. Commit these changes to a new branch, get it approved and merged, and switch to the up-to-date main.

5. Publish the crates. ./resources/scripts/release.sh orchestrates the process.

   • You will be prompted to review changes along the way

   # To see usage
   ./resources/scripts/release.sh
   # To do the thing
   ./resources/scripts/release.sh sleipnir

Examples

tosvg

tosvg is a command-line tool that converts all glyphs in a font file to individual SVG files.

# Convert all glyphs in a font to SVGs in /tmp/output
cargo run --example tosvg -- --font path/to/font.ttf --output-dir /tmp/output

# Convert with specific variational coordinates (e.g., for a variable font)
cargo run --example tosvg -- --font path/to/font.ttf --coords 0.5,1.0
