Package design
type Git interface {
// Branches returns PR source and target branch
Branches() (source, target string)
// Commits returns PR commits
Commits() []Commit
// Changes returns PR repository files diff
Changes() []FileChange
}
Few methods to create it:
InitPRcreates diff between current and target branch (like PR diff)InitLastcreates diff for last N current branch commits
Why publicity and full abstraction from go-git:
- Current benefit for this project. Package can be used now for checks automation via go scripts.
- Current benefit for my work projects. Package can be used outside this project as library.
- Full DI control in other packages tests.
