Add a setting for mapping file extensions to syntax highlighters for diffs
Review Request #11821 — Created Sept. 25, 2021 and submitted — Latest diff uploaded
Previously, we guess what syntax highlighting to apply to files in the diff
viewer given their data and file extension. Sometimes this guess would be wrong,
and we have no way of setting what type of syntax highlighting gets applied to
files. This change adds a setting for mapping file extensions to pygments
lexers (the syntax highlighters), namely
reviewboard.admin.siteconfig.diffviewer_custom_pygments_lexers
. If a mapping
is not defined for a certain file extension, we revert to the old behaviour
of guessing which lexer to use given the filename and file contents.Adds
reviewboard.admin.form_widgets.LexersMappingWidget
which partly
handles the UI for modifying this mapping.
- Created unit tests for the mapping in
reviewboard.diffviewer.tests.test_raw_diff_chunk_generator
.
Ran all unit tests inreviewboard.diffviewer
with success - Created the unit tests for the LexersMappingWidget in
reviewboard.admin.tests.test_lexers_mapping_widget
.
Ran all unit tests inreviewboard.admin.tests
with success.
