* break: Fix up word fixupsMatthias Clasen2021-08-261-7/+14
| | | | | | | We were not correctly handling overlapping segments in all cases, with <span segment='word'>. Improve this. Update affected tests.
* break: Fix sentence boundary corner casesMatthias Clasen2021-08-261-2/+2
| | | | | | We were not correctly handling the case where wipe out a sentence boundary after the fact, and were leaving behind a stray sentence end.
* break: Follow mandatory rules more strictlyMatthias Clasen2021-08-261-4/+25
| | | | | | | | We were not putting a line break at the end of the text, in cases where a paragraph ends with a newline. Enforce this in all break apis. Update affected tests.
* Add segmentation attributesbreak-tailoringMatthias Clasen2021-08-251-47/+363
| | | | | | | Add attributes that let us override word and sentence boundaries (and, indirectly, line breaks). Tests included.
* test-break: Print out hyphensMatthias Clasen2021-08-251-7/+3
| | | | | | Print out all the log attrs we have. Update expected test outputs.
* Refine hyphenationMatthias Clasen2021-08-251-2/+13
| | | | | | | | Replace ‧ and | with a - when we break there. Update affected test output. Fixes: #603
* Add hyphens to log attrsMatthias Clasen2021-08-241-3/+102
| | | | | | The code computing this is much better off in break.c, so move it there, and keep the information in the log attr array.
* break: Add pango_attr_break apiMatthias Clasen2021-08-231-2/+40
| | | | | | | | | | | | So far, we've been applying attribute-based customization while doing per-item tailoring. But this is suboptimal, since it means we don't have a full view of the log attrs, and can't do invariant fixes that cross item boundaries. Therefore, add a separate pango_attr_break api that applies attributes to to the whole paragraph, and make PangoLayout use it.
* break: Some code reorganizationMatthias Clasen2021-08-231-46/+56
| | | | Shuffle break.c around a bit.
* break: Silence compiler warningsMatthias Clasen2021-08-221-8/+16
|
* break: Some code reorgMatthias Clasen2021-08-221-141/+130
| | | | Reshuffle things to make room for validation.
* Cosmetics: Move a function aroundMatthias Clasen2021-08-201-105/+0
| | | | | pango_find_paragraph_boundary has nothing to do with breaks, so move it to pango-utils.h
* Use the language we are givenlog-attr-languageMatthias Clasen2021-08-191-0/+1
| | | | | | pango_get_log_attrs was not using its language argument at all. Pass it into pango_default_break as part of the PangoAnalysis struct.
* break: Fix handling of tag sequencestests-and-fixesMatthias Clasen2021-07-071-0/+7
| | | | | | | | Correctly classify tag characters as Grapheme_Extend, so that we don't end up putting grapheme boundaries in the middle of tag sequences. Includes a test.
* docs: Convert gtk-doc syntax leftoversdocs-cleanupMatthias Clasen2021-05-191-30/+39
| | | | | Remove leftovers like #Type, reduce indentations to avoid markdown block quotes, etc.
* break: Fix an inconsistency with sentence breaksfix-sentence-breaksMatthias Clasen2021-05-091-3/+16
| | | | | | | | | | | When we retroactively remove a sentence boundary because of rule SB8, we were not cleaning up the sencence_start/end markers that have already been derived from it. This can be seen in urls like http://www.unicode.org/reports/tr29, where we don't have any sentence boundaries, but we leave a stray sentence_start/end at the first / after ".org".

* break: Don't determine types more than onceMatthias Clasen2019-10-121-3/+5
| | | | | | We determined the category early on, don't do the same work again later by calling isdigit or isletter wrappers.
* Ensure arguments name match the documentationEmmanuele Bassi2019-08-021-2/+2
| | | | Otherwise the introspection scanner will be majorly confused.
* Annotate implicit fallthroughMatthias Clasen2019-08-011-0/+1
| | | | This triggers compiler warnings.
* Fix a crash with line break controlMatthias Clasen2019-07-271-1/+1
| | | | | We were forgetting to copy allow-break attributes, causing them to be prematurely freed. Oops.
* Add a missing Since tagMatthias Clasen2019-07-201-0/+2
|
* break: Implement allow-breaksMatthias Clasen2019-07-201-9/+87
| | | | | | | | | We implement this in pango_tailor_break(), after the script-specific breaking. When line breaks are forbidden in a range, we remove line and char break opportunities inside the range.
* Add an offset argument to pango_tailor_breakMatthias Clasen2019-07-201-0/+2
| | | | | | Without this, it is not possible to interpret attributes, whose offsets are relative to the beginning of the paragraph.

| | | | | To break correctly, use pango_default_break and pango_tailor_break.
* Add pango_tailor_breakMatthias Clasen2019-07-161-16/+42
| | | | | | This function lets you apply language-specific tailoring on top of breaks produced by pango_default_break.

| | | | | | | | | | Drop all internal use of language engines. The lang_engine field in PangoAnalysis is now unused.
| * break: Call break_script directlyMatthias Clasen2019-07-091-11/+17
| | | | | | | | No need to go through the engine api anymore.

* break: Mark breaks induced by soft hyphensMatthias Clasen2019-07-071-1/+8
| | | | | | Use a bit in PangoLogAttr to mark line breaks that are due to soft hyphens; we want to insert hyphens here later, if the break is taken.
* Respect Dependent Vowels for Indic languagePeng Wu2019-04-091-63/+7
| | | | For Dependent Vowels, the grapheme needs to be deleted by character.

* Clarify docs around text inputMatthias Clasen2018-12-121-3/+3
| | | | | | | Make it clear that all text input must be valid UTF-8, except in the case pango_layout_set_text, which we now officially document as accepting and handling invalid input.
