* test-break: Print out hyphensMatthias Clasen2021-08-251-7/+3
| | | | | | Print out all the log attrs we have. Update expected test outputs.
* Refine hyphenationMatthias Clasen2021-08-254-20/+82
| | | | | | | | Replace ‧ and | with a - when we break there. Update affected test output. Fixes: #603
* shape: Rearrange hb buffer setupMatthias Clasen2021-08-251-8/+7
| | | | | Rearrange the buffer setup code slightly, so that we can change it easier, later.
* layout: Use need_hyphen from log attrsMatthias Clasen2021-08-241-130/+1
|
* Add hyphens to log attrsMatthias Clasen2021-08-242-3/+105
| | | | | | 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 Clasen2021-08-233-9/+62
| | | | | | | | | | | | 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 Clasen2021-08-232-49/+60
| | | | Shuffle break.c around a bit.
* break-thai: Fix up word break handlingMatthias Clasen2021-08-231-8/+20
| | | | | | | | | | | We want to insert word start+end if libthai hands us line breaks between letters. But must be careful not to overwrite existing word boundaries, or we end up with a nonsense sequence. This was found by checking log attr invariants. Regenerate affected test outputs.
* layout: Only recompute log_attrs when neededMatthias Clasen2021-08-231-15/+21
| | | | | | There is no need to throw away the log_attrs when we just change the width, or other layout properties that do not affect segmentation.
* docs: Add another illustrationdoc-font-metricsMatthias Clasen2021-08-221-0/+8
| | | | Show font metrics.
* Fix an oversight with text-transformMatthias Clasen2021-08-221-1/+1
| | | | | With the current implementation of text-transform, we need the attribute to be constant across runs.

| * renderer: Don't divide by zerorenderer-crashMatthias Clasen2021-08-211-1/+1
| | | | | | | | | | | | | | | | Before dividing by num_glyphs in draw_strikethrough, make sure it isn't 0. This should fix reported crashes in this function. Fixes: #599

| * shaping: implement text transformMatthias Clasen2021-08-201-81/+167
| | | | | | | | | | | | Transform the text we hand to harfbuzz, as prescribed by the text transform attributes we have. This uses the log attrs to find word starts.
| * layout: Use pango_shape_itemMatthias Clasen2021-08-201-4/+5
| | | | | | | | Use the new API, and pass our log attrs along.
| * Add pango_shape_itemMatthias Clasen2021-08-202-38/+103
| | | | | | | | | | | | Add a pango_shape API variant that takes log attrs, so we can implement text transforms that depend on word boundaries, in the future.
| * layout: Text transform affects shapeMatthias Clasen2021-08-201-0/+1
| | | | | | | | | | Classify text transform as an attribute that affects shaping. It will, in the future.
| * markup: Add a text transform attributeMatthias Clasen2021-08-203-0/+62
| | | | | | | | | | | | Add a PangoTextTransform enum, a PangoAttribute to set it on runs of text, and support for parsing it out of markup.
