Overview ¶
package fsync keeps two files or directories in sync.
err := fsync.Sync("~/dst", ".")
After the above code, if err is nil, every file and directory in the current directory is copied to ~/dst and has the same permissions. Consequent calls will only copy changed or new files.
SyncTo is a helper function which helps you sync a groups of files or directories into a signle destination. For instance, calling
SyncTo("public", "build/app.js", "build/app.css", "images", "fonts")
is equivalient to calling
Sync("public/app.js", "build/app.js")
Sync("public/app.css", "build/app.css")
Sync("public/images", "images")
Sync("public/fonts", "fonts")
Actually, this is how SyncTo is implemented: consequent calls to Sync.
By default, sync code ignores extra files in the destination that don’t have identicals in the source. Setting Delete field of a Syncer to true changes this behavior and deletes these extra files.
