Prerequisites

• .NET 10 SDK or newer

---

Running (dev)

cd src/GtPlus
dotnet run

Then use File › Open to load a .gtzip file.

Building a release binary

Run the build script from the repository root:

./build.ps1

Options

Command	Effect
./build.ps1	Bump patch, build all platforms
./build.ps1 -Bump Minor	Bump minor (patch resets to 0)
./build.ps1 -Bump Major	Bump major (minor and patch reset to 0)
./build.ps1 -Bump None	Rebuild the current version in place
./build.ps1 -SetVersion 1.0.0	Build an exact version
./build.ps1 -Rid win-x64	Build a subset of platforms
./build.ps1 -NoArchive	Skip the .zip / .tar.gz step
./build.ps1 -NoBundleNative	Leave Skia/HarfBuzz beside the executable

Windows cannot set the Unix executable bit, so the Linux and macOS binaries need chmod +x GTPlus-<version> after extraction.

Manual publish

dotnet publish src/GtPlus -c Release -r win-x64 --self-contained -p:PublishSingleFile=true -o dist/win-x64

Substitute linux-x64, osx-x64 or osx-arm64 for other platforms.
