:mod:`trac.versioncontrol.diff` -- Utilities for generation of diffs
====================================================================
.. automodule :: trac.versioncontrol.diff
Synopsis
--------
`get_filtered_hunks`, `get_hunks` are low-level wrappers for Python's
`difflib.SequenceMatcher`, and they generate groups of opcodes
corresponding to diff "hunks".
`get_change_extent` is a low-level utility used when marking
intra-lines differences.
`diff_blocks` is used at a higher-level to fill the template data
needed by the "diff_div.html" template.
`unified_diff` is also a higher-level function returning differences
following the `unified diff`_ file format.
Finally, `get_diff_options` is an utility for retrieving user diff
preferences from a `~trac.web.api.Request`.
