* More work on line stylesMatthias Clasen2022-02-131-2/+2
|
* Rename PangoUnderline to PangoLineStyleMatthias Clasen2022-02-131-4/+4
|
* Split off and underline position attributeMatthias Clasen2022-02-131-2/+2
| | | | Make the 'low' positioning a separate attribute.
* Drop some underline variantsMatthias Clasen2022-02-131-2/+2
| | | | Make them always behave like _LINE.
* Change color attr apiMatthias Clasen2022-02-132-11/+11
| | | | | Make pango_attr_{fore,back}ground_new take a PangoColor*. Update all callers.
* Rename pango_attribute_get_customMatthias Clasen2022-02-131-2/+2
|
* Add PangoAttrMerge flagsMatthias Clasen2022-02-131-0/+1
| | | | | This generalizes the behavior of PangoAttrIterator wrt to merging attributes with overlapping ranges.
* Add PangoAttrAffectsMatthias Clasen2022-02-131-4/+8
| | | | | | | Declare what part of the pipeline an attribute affects as part of the type. This lets us handle attribute filtering for that purpose in a generalized fashion.
* Redo attributesMatthias Clasen2022-02-136-78/+122
| | | | | | | Do away with PangoAttribute subclassing, and turn the PangoAttribute struct into a union. Redo custom attribute registration to be more useful.
* Drop shape attributesMatthias Clasen2022-02-133-7/+0
| | | | | | Shape attributes don't fit well with the other attributes, and user fonts are a better way of doing custom glyphs.
* testhbfont: update for generic familiesuserfontMatthias Clasen2022-02-131-7/+9
|
* tests: AdaptMatthias Clasen2022-01-281-5/+5
|
* test-itemize: Leave out faceidsimple-fontmapMatthias Clasen2022-01-281-0/+2
| | | | | | | | | | The faceid in the serialized font description would make the test output backend-dependent, so leave it out for now. This makes PANGOCAIRO_BACKEND=fc2 ./test-itemize succeed.
* serializer: Improve font serializationMatthias Clasen2022-01-285-0/+11
| | | | | | | Include index and instance_id in the output when serializing fonts. Update all affected tests.
* test-shape: Use a simple fontmapMatthias Clasen2022-01-281-2/+10
| | | | This is experimental to see how far we can take this.
* Add PangoFcHbFontMap testsMatthias Clasen2022-01-281-0/+423
|
* Add PangoFcHbFontMapMatthias Clasen2022-01-281-0/+4
| | | | | | | | | This is a new fontmap implementation that works by populating a PangoHbFontMap from fontconfig data. It relies on the base class to provide caching and lookups. In contrast to the existing fontconfig fontmap, this does not include every font in every fontset.
* Add tests for PangoHbFace and PangoHbFontMatthias Clasen2022-01-283-0/+498
| | | | | Add dedicated tests for various aspects of PangoHbFont and PangoHbFace functionality.
* Add a faceid field to font descriptionsMatthias Clasen2022-01-281-13/+63
| | | | | | | | | | The faceid will be used in future commits to improve font -> description -> font roundtrip accuracy. Update affected tests. Minimal test included.
* Add some useful face apiMatthias Clasen2022-01-281-0/+37
| | | | | | | | Add pango_font_face_supports_language and pango_font_face_get_languages. There is no particular reason to tie language information to fonts instead of faces. This will be useful for the font chooser. Update the fontconfig implementation for these changes.
* font: Add pango_font_face_is_variable/monospaceMatthias Clasen2022-01-281-3/+10
| | | | | | | | | | These are really properties of the individual faces, not the family. The default implementations of these functions simply return the corresponding family value. Add some tests for the new api.
* Quiet down break testsMatthias Clasen2022-01-212-15/+15
| | | | | | | | | The output from the testboundaries tests just overwhelms the test reports and makes it hard to find the actual problems. Stop that. You can still get the noise, by passing --verbose to the tests.
* Fix allow_breaks handlingfix-allow-breaksMatthias Clasen2022-01-201-1/+1
| | | | | | | | | handling of segmentation attributes can introduce line breaks, after we removed them in allow_breaks handling. Change the order to handle allow_breaks last, so this doesn't happen. Update affected tests.
* Fix a g_ascii_formatd callfix-asciid-callMatthias Clasen2022-01-186-19/+19
| | | | | | | | | | | We were passing a format specifier that starts with ' ', which some implementations of that API don't like. This change removes an extraneous space from the output. Update affected tests. Fixes: #659
* Drop uses of pango_coverage_ref/unrefMatthias Clasen2022-01-101-3/+3
| | | | Just use g_object_ref/unref.
* Add a bold sans to the test font setupMatthias Clasen2022-01-102-0/+1
|
* Reinstate previous behavior or pango_attr_list_spliceattrlist-spliceMatthias Clasen2022-01-071-0/+18
| | | | | | | | | | If gap is zero, don't limit the inserted attributes; that does not make sense. Spell out the different use cases in the docs. Testcase included. Fixes: #653
* Merge branch 'matthiasc/for-main' into 'main'Matthias Clasen2022-01-022-0/+136
|\ | | | | | | | | Add a test for letterspacing See merge request GNOME/pango!570
| * Add a test for letterspacingMatthias Clasen2022-01-022-0/+136
| | | | | | | | | | This tests that we turn off ligatures when letterspacing is enabled.
* | Add pango_matrix_get_slant_ratioMatthias Clasen2022-01-021-0/+26
|/ | | | | Add API to extract the slant ratio from a PangoMatrix. Tests included.
* test-ellipsize: TweakMatthias Clasen2022-01-011-2/+2
| | | | | Best to compare precise sizes and take rounding out of the equation.
* Add fonts to installed testsMatthias Clasen2021-12-251-0/+14
| | | | Fixes: #648
* Make missing space smallersmaller-spaceMatthias Clasen2021-12-222-7/+7
| | | | | | | The Microsoft paper I was citing actually recommends 1/4 em for ASCII space. Make it so... Update affected tests.
* Use a better size for missing spaceMatthias Clasen2021-12-212-7/+7
| | | | | | | | | | Follow the Microsoft Typography recommendations from https://docs.microsoft.com/en-us/typography/develop/character-design-standards/whitespace and use half of an em for missing space. Update affected tests. Fixes: #647
* Add a test for the previous commitsmisc-cleanupsMatthias Clasen2021-12-182-0/+296
| | | | | This test verifies the fixes for the situation described in #646.
* serializer: Fix a typoMatthias Clasen2021-12-1835-35/+35
| | | | | | Oops, we were not serializing the height at all. Update all affected tests.
* cairo: Work harder to measure spacemore-space-tweaksMatthias Clasen2021-12-172-18/+12
| | | | | | | | | | | When coming up with a width for a missing space, we were just measuring the hex digits. But in subsetted fonts, such as the ones we use for ci, hex digits might well be missing. Take that into account and still provide some nonzero width for space. Update affected tests.
* shape: More tweaks to space handlingMatthias Clasen2021-12-172-18/+24
| | | | | | | | | | | | | | It is a difficult dance between HarfBuzz and pango which glyphs we let hb synthesize, and which ones we need to fake ourselves. HarfBuzz knows how to create other spaces from 0x20, so if the font is lacking spaces, we want to tell HarfBuzz that we don't have that glyph *except* for 0x20 where we need to fake one, and provide HarfBuzz with a suitable width. Update affected tests.
* Revert "Fix advance widths with transforms"fix-vertical-regressionMatthias Clasen2021-12-1716-41/+302
| | | | | | | | | This reverts commit ccb651dd2a876a4f4a4cb9351f05332173e709ba. This broke vertical text rendering, see https://gitlab.com/inkscape/inkscape/-/issues/2950. Update affected tests and add a vertical test.
* Fix handling of space-less fontsfix-spaceless-fontsMatthias Clasen2021-12-166-13/+151
| | | | | | | | | | | HarfBuzz knows how to synthesize spaces, we just need to tickle it in the right way. Test included. Update affected tests. Fixes: #641
* Add a test for 0x6ddarabic-formatMatthias Clasen2021-12-164-0/+92
| | | | This tests the fix in the previous commit.
* tests: Cover new tab alignmentsMatthias Clasen2021-12-101-7/+15
|
* layout: Handle a corner caseMatthias Clasen2021-12-092-0/+184
| | | | | | | | | We can't break in a tab run. This fixes an assertion found by afl. Testcase included. Fixes: #638
* Fix line width computationMatthias Clasen2021-12-062-0/+364
| | | | | | | | | | We an only use the line_width - remaining_width shortcut if we are actually maintaining remaining_width, i.e. not if we don't wrap lines. Testcase included. Fixes: #635
* Add a monospace font for ciMatthias Clasen2021-12-064-16/+22
| | | | Update affected test outputs.
* Fix a crash in tab handlingtab-crash-fixMatthias Clasen2021-12-052-0/+1430
| | | | | | | | | | When we uninsert the current tab run, we need to reset our tab state to prevent last_tab->glyphs to become a dangling pointer. Test included. Fixes: #634
* Add pango_font_deserializeMatthias Clasen2021-12-021-1/+14
| | | | | This will make the font serialization useful in GTK, where we serialize fonts in node files.
* Update tests for small changes in outputMatthias Clasen2021-12-0229-1225/+1204
|
* testserialize: Fix the testsMatthias Clasen2021-12-021-13/+23
|
* layout: Small optimizationMatthias Clasen2021-12-022-14/+14
| | | | | Don't calculate line width the hard way when we can do it much easier.
