* Don't compute log attrs on demandMatthias Clasen2021-08-291-15/+3
| | | | If we don't have them, just do the fallback.
* Add pango_glyph_string_index_to_x_fullMatthias Clasen2021-08-291-24/+61
| | | | | | This variant of pango_glyph_string_index_to_x takes log attrs so it does not have to compute them when it needs them to determine grapheme boundaries.
* Try harder to disect clustersMatthias Clasen2021-08-291-15/+34
| | | | | | | | | | We need to take into account whether the characters we are counting are actually cursor positions, else we are bound to look for more carets than the font has available, sometimes. This change would benefit from passing log attrs into pango_glyph_string_index_to_x.
* Try harder to find positions in clustersMatthias Clasen2021-08-271-3/+32
| | | | | | | Try to find a single non-mark glyph in a multi-glyph cluster to use its ligature caret information. This fixes situations in Arabic where you can have marks on top of ligatures, e.g. ﻉﻭ.
* Take kerning into account for ligature caretsMatthias Clasen2021-08-271-0/+3
| | | | | | | The ligature caret positions returned by hb_ot_layout_get_ligature_carets are 'unshaped' metrics. We need to take the kerning into account that is applied during shaping, and shows up in the glyphstring as x_offset.
* Fixes for rtl cursor positionsMatthias Clasen2021-08-271-1/+4
| | | | Still not working quite right, but getting closer.
* doc: Update pango_glyph_string_index_to_xMatthias Clasen2021-08-261-2/+9
| | | | | | What the docs were saying is no longer strictly true, now that we are using font metrics. Update them, and add an illustration.
* Use ligature caret listsligature-caretsMatthias Clasen2021-08-251-36/+89
| | | | | | | | Some fonts provide information about where to place carets inside ligatures. Use it, when it is available. Fixes: #39
* glyphstring: Silence compiler warningsMatthias Clasen2021-08-221-4/+4
|
* Add a few missing constglyph-string-const-charMatthias Clasen2021-08-171-12/+12
| | | | | We should only pass char * when we actually modify the string. Everything else is const char *.
* docs: Reduce redundancydocs-cleanupsMatthias Clasen2021-05-201-2/+0
| | | | | | Remove a boatload of "or %NULL" from nullable parameters and return values. gi-docgen generates suitable text from the annotation that we don't need to duplicate.
* docs: Convert gtk-doc syntax leftoversdocs-cleanupMatthias Clasen2021-05-191-43/+36
| | | | | Remove leftovers like #Type, reduce indentations to avoid markdown block quotes, etc.
* introspection: Stop using allow-noneMatthias Clasen2021-05-191-2/+2
| | | | | The allow-none annotation has been deprecated for a long time already. Instead use optional and nullable everywhere.
* Use g_memdup2()memdup2Matthias Clasen2021-03-181-5/+5
| | | | | The g_memdup() function is replaced by a safer version in newer versions of GLib.
* docs: Tweak glyphstring docsMatthias Clasen2021-03-111-44/+52
| | | | Give doc comments summaries, etc.
* docs: Add extent imagesMatthias Clasen2019-08-041-0/+4
| | | | Add an illustration of logical and ink rects.

* Bug 596614 - Pango application receives SIGSEGV on pasting text with U+202EBehdad Esfahbod2009-11-171-2/+0
| | | | | Fixed all modules to reverse glyphs if run is rtl. Except for Hangul module. Fixed pango_shape() to detect that, warn, and reverse.
* New public API: pango_glyph_item_get_logical_widths()Behdad Esfahbod2009-08-121-35/+4

* Handle NUL in text in places that g_utf8_strlen () was usedBehdad Esfahbod2009-07-151-2/+4
| | | | | | | | | | While pango-layout doesn't allow NUL in text, the lower level API should handle it correctly. We were using g_utf8_strlen() in a number of places. This is problematic since that function stops processing at NUL even if length>1. We now use an internal pango_utf8_strlen() instead. Inspired by: Bug 588678 – pango crash: install a new theme from gnome-appearance-properties
* Bug 580987 – SIGFPE in pango_glyph_string_index_to_xBehdad Esfahbod2009-05-011-0/+6
