Add a new Identity type with the required methods so that now the board
types (Card, Status and soon Tag) can automatically satisfy the BoltItem
interface.
Main change:
Add restrictions when adding IDs for cards and statuses. Errors are
returned when an attempt is made to set an ID lower than 1, or an
attempt is made to set an ID that has already been set.
Additional changes:
- Error types in the board packages are now defined in errors.go.
- Small formatting to error messages.
Changes:
- Rename the UI type to App.
- Rename NewUI() to NewApp().
- Move init functions to internal/ui/ui.go.
- Call app's initialisation function from main.
- Move the keymapping functionalities to internal/ui/keymappings.go.
- Add documentation for updateColumn() and updateAllColumns().
- Applied gofmt.
Also:
- Build(mage): optionally include -a and/or -v during go build.
