Similar::Algorithms::DiffHook

Inherits Reference < Object

A trait for reacting to an edit script from the "old" version to the "new" version.

Instance methods

delete(old_index : Int32, old_len : Int32, new_index : Int32) : Nil

Called when a section of length old_len, starting at old_index, needs to be deleted from the old version.

Source
equal(old_index : Int32, new_index : Int32, len : Int32) : Nil

Called when lines with indices old_index (in the old version) and new_index (in the new version) start an section equal in both versions, of length len.

Source
finish

Always called at the end of the algorithm.

Source
insert(old_index : Int32, new_index : Int32, new_len : Int32) : Nil

Called when a section of the new version, of length new_len and starting at new_index, needs to be inserted at position old_index.

Source
replace(old_index : Int32, old_len : Int32, new_index : Int32, new_len : Int32) : Nil

Called when a section of the old version, starting at index old_index and of length old_len, needs to be replaced with a section of length new_len, starting at new_index, of the new version.

The default implementations invokes delete and insert.

You can use the Replace hook to automatically generate these.
