Functions

func FixFile

func FixFile(oldFile *bf.File) *bf.File

FixFile updates rules in oldFile that were generated by an older version of Gazelle to a newer form that can be merged with freshly generated rules.

func MergeWithExisting

func MergeWithExisting(genFile, oldFile *bf.File) *bf.File

MergeWithExisting merges "genFile" with "oldFile" and returns the merged file.

"genFile" is a file generated by Gazelle. It must not be nil. "oldFile" is the existing file. It may be nil if no file was found.

If "oldFile" is nil, "genFile" will be returned. If "oldFile" contains a "# gazelle:ignore" comment, nil will be returned. If an error occurs, it will be logged, and nil will be returned.
