Golang Repo.GetCoreEditor方法代碼示例

// LaunchEditor launches the default editor configured for the given repo. This
// method blocks until the editor command has returned.
//
// The specified filename should be a temporary file and provided as a relative path
// from the repo (e.g. "FILENAME" will be converted to ".git/FILENAME"). This file
// will be deleted after the editor is closed and its contents have been read.
//
// This method returns the text that was read from the temporary file, or
// an error if any step in the process failed.
