DiffGranularity
is an option to Diff and related functions that indicates with what granularity to compare the given expressions.
Details
- Valid settings for DiffGranularity depend on the expressions being compared.
- Settings for DiffGranularity include:
-
"Lists" compare lists by item"Characters" compare strings character by character"Words" compare strings one word at a time"Lines" compare strings or files one full line at a time"Cells" compare one Cell with another"Notebooks" compare one Notebook with another
- The default setting of Automatic will choose an appropriate granularity for the given expressions.
- The default granularity depends on the heads of the expressions being diffed:
-
List "Lists"Cell "Cells"ExpressionCell "Cells"TextCell "Cells"CellObject "Cells"Notebook "Notebooks"NotebookObject "Notebooks"
