Flatpak Go modules helper

This CLI tool generates Flatpak sources directives for Go modules.

It helps avoid exposing network access to Flatpak build step, which is one of the requirements for publishing to Flathub.

Usage

go run github.com/dennwc/flatpak-go-mod@latest ./path/to/your/project

It will generate following files: go.mod.yml (or go.mod.json) and modules.txt.

Contents of go.mod.yml (or go.mod.json) should be copied into sources directives of Flatpak YAML. These directives will populate ./vendor during Flatpak build with all dependencies of your project, downloading them directly from Go modules mirror.

The modules.txt file should be copied into your Flatpak directory, which will be added to ./vendor directory during Flatpak build as well.

Then, build your Go project as usual. It should detect vendor directory automatically. You can also pass -mod=vendor to force vendoring mode during build.
