* item: Add a char offsetMatthias Clasen2021-08-281-3/+4
| | | | | | | | | | | | | Add a char_offset field to PangoItem, compute it as part of itemization and update it when splitting items. Keeping this number around cuts down on the amount of list and utf8 walking we need to do later. We have to do some extra shenanigans to preserve abi in the face of pango's open-coded structs, so we introduce a PangoItemPrivate type that is used internally. On 64bit, PangoItem has a 4 byte whole, so we can keep the size of PangoItemPrivate the same. No such luck on 32bit.
* Cosmetics: Move a function aroundMatthias Clasen2021-08-201-0/+4
| | | | | Move pango_reorder_items to pango-item.h, since it is abou items, not about glyphs.
* Some code reorgMatthias Clasen2021-08-201-0/+3
| | | | | Split the itemization code into its own file, and move things around a bit.
* Cosmetics: Reindent pango-item.hMatthias Clasen2021-08-201-23/+24
|
* Cosmetics: Clean up pango-context.hMatthias Clasen2021-08-201-0/+17
| | | | | Move itemize functions to pango-item.h, and move the PangoContext typedef to pango-types.h.
* docs: Tweak glyph item docsMatthias Clasen2021-03-111-5/+4
| | | | Add summaries, convert markup, etc.
* Drop some useless things from the girMatthias Clasen2021-03-111-0/+5
| | | | | We don't need the deprecated and useless module and engine types in the gir and the docs.
* docs: Port PangoItem to the new doc formatMatthias Clasen2021-03-111-4/+7
| | | | Replace gtk-doc'isms and use gi-docgen links instead.
* Don't insert extra runs for hyphensMatthias Clasen2019-07-201-1/+11
| | | | | | | | | Instead, reshape the pre-break run with the soft hyphen replaced by an actual hyphen. This is unfortunately inefficient, we copy the entire text for this. The alternative (scatter-gather populating the harfbuzz buffer) is too hard to manage.
* Document engines as unusedMatthias Clasen2019-07-181-2/+2
|
* Clean up docs a bitMatthias Clasen2019-07-131-2/+2
| | | | Avoid duplicate comments in struct defintions.
* Add pango_item_apply_attrsMatthias Clasen2019-07-111-0/+4
| | | | | This adds attrs that are overlapping the range of the item to the extra_attrs in the analysis.
* Decorate the symbols in the headers with version macrosChun-wei Fan2016-06-291-0/+5
| | | | | | | From the last commit, decorate all the symbols with the version macros. Also add the version macros in the docs. https://bugzilla.gnome.org/show_bug.cgi?id=767587
* Minor doc fixBehdad Esfahbod2015-05-051-0/+4

* Add an analysis flag to mark the ellipsis runMatthias Clasen2014-09-021-2/+11
| | | | | | | | | | | Without this, it is hard to determine if you are 'inside the ellipsis'. We need to know this in GTK+, e.g. to skip link processing. I decided not to turn the flags into an enum at the time to avoid possible language binding problems. https://bugzilla.gnome.org/show_bug.cgi?id=735719
