Behdad Esfahbod 7c704d89 2022-01-28T12:38:32 [buffer] Make hb_buffer_append() take a const argument
Khaled Hosny fa29006b 2022-01-27T01:57:45 [doc] Fix generation of hb_glyph_flags_t docs GTK-Doc does not like the empty lines here, and interprets everything after the first empty line as the description of the enum itself not a specific member and the generated text makes no sense. Removing the empty lines makes the text harder to read (both in source and HTML), but at least it is correctly organized.

Behdad Esfahbod da500568 2021-10-26T08:02:29 [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph Instead of using gid=0 when a character is not found in the font, client can now set a custom value. This is useful for shaper-driven font fallback and to differentiate that from .notdef glyph. Fixes https://github.com/harfbuzz/harfbuzz/issues/1360

Behdad Esfahbod 3b7aa651 2018-02-09T15:43:20 [docs] Improve UNSAFE_TO_BREAK docs
bungeman 671f0a77 2018-02-01T13:31:25 Documentation for HB_GLYPH_FLAG_UNSAFE_TO_BREAK. HB_GLYPH_FLAG_UNSAFE_TO_BREAK means that the glyph with this flag is somehow affected by the previous logical glyph (the previous index in the buffer if ltr and the next index if the buffer is rtl). If these two glyphs are separated by a break (line or otherwise) then the underlying text should be re-shaped on both sides up to corresponding position in the text of some glyph not marked with this flag.
Bruce Mitchener 19a93fcf 2018-01-21T20:40:34 Fix typos.
Khaled Hosny 0b22da95 2018-01-10T07:12:07 Improve HB_BUFFER_SERIALIZE_FLAG_NO_ADVANCES docs Add the note about absolute glyph positions from the commit message.

Behdad Esfahbod 71fd6325 2018-01-10T02:20:14 Add option to buffer serialization to not output glyph advances When advances are not printed, glyph offsets reflect absolute glyph positions. New API: HB_BUFFER_SERIALIZE_FLAG_NO_ADVANCES hb-shape --no-advances
Behdad Esfahbod fbb937b6 2017-10-15T12:04:16 Don't use NULL in public headers
fanc999 48a94068 2017-10-07T18:57:14 Fix build of HarfBuzz tools and HarfBuzz-GObject on Visual Studio (#555) * hb-buffer.h: Mark hb_buffer_diff() for export This will fix the tools builds on Visual Studio, as the symbol is used by the tools. * build: Adapt NMake Makefiles for GLib 2.53.4 or later glib-mkenums was ported from a PERL script to a Python script, so we need to update how we generate the enum sources for HarfBuzz-GObject in the NMake builds. Let this be known in the build documentation for MSVC builds. One of the problems with the underlying cmd.exe that the NMake Makefiles run on is that shebang lines are not recognized, so we need to to test run the script with Python and see whether it succeeded by outputing a source file that is larger than 0 in file size (since running the PERL version of the script will clearly fail and cause an empty file to be created). If it succeeds, we then run a small Python utility script that makes the necessary string replacements, and we are done. If that fails, then we run the glib-mkenums script with PERL, and do the replacements with the PERL one-liners as we did before. We need to make replace.py use latin-1 encoding when using Python 3.x to cope with the copyright sign that is in the generated enum sources.
Behdad Esfahbod d03f11f2 2017-09-04T20:14:13 Fix buffer_diff for empty buffers If buffers are empty, content type should be ignored. This fixes last of the failing tests: fuzzed.tests. Green again!
Behdad Esfahbod b2dd0c1c 2017-08-23T13:12:54 Add hb_glyph_info_get_glyph_flags() New API.
Behdad Esfahbod 3e8f4f14 2017-08-22T17:56:25 Rename HB_BUFFER_DIFF_FLAG_MASK_MISMATCH to HB_BUFFER_DIFF_FLAG_GLYPH_FLAGS_MISMATCH

Jonathan Kew 331d66c7 2014-07-19T23:09:09 Add function to compare two buffers Based on patch from Jonathan Kew. Needs more cleaning up and documentation. New API: hb_buffer_diff_flags_t hb_buffer_diff()
Behdad Esfahbod 39a97494 2017-08-11T15:52:06 New API: hb_buffer_append()
Behdad Esfahbod 5287ccc9 2017-08-10T14:25:53 [unsafe-to-break] Allocate public bits from 0
Behdad Esfahbod 40bd7e9a 2016-05-02T14:47:45 [unsafe-to-break] Add UNSAFE_TO_BREAK flag Not all shapers code is updated to set this properly. GSUB and Arabic shaper are updated. GPOS and other shapers are NOT. Fixes https://github.com/behdad/harfbuzz/issues/224
Behdad Esfahbod 97624d92 2016-01-11T12:58:45 [docs] Minor fixes.
Khaled Hosny 9ab9f974 2016-01-01T20:38:21 [docs] More buffers documentation

Behdad Esfahbod 0475ef2f 2015-12-18T18:17:07 [buffer] Add debugging, aka, message, API Currently just announces lookup applications. Message-API *will* change. hb-shape / hb-view are updated to print-out messages to stder if --debug is specified.
Chun-wei Fan 835bbdc7 2015-11-19T18:34:12 Public headers: Decorate public symbols with HB_EXTERN This prepares the headers for exporting symbols using visibility attributes or __declspec(dllexport), so that we do not need to maintain symbols listing files, as this is what was and is done in GLib and GTK+.
Behdad Esfahbod b8811429 2015-09-03T15:53:22 Fix Since tags Fixes https://github.com/behdad/harfbuzz/issues/103
Behdad Esfahbod fdd1770e 2015-08-24T13:49:55 Add API/cmdline to show glyph extents when serializing buffer New API: HB_BUFFER_SERIALIZE_FLAG_GLYPH_EXTENTS hb-shape now accepts --show-extents. Patch from Simon Cozens.
Behdad Esfahbod 376d587f 2015-07-22T16:51:12 Implement more granular cluster-merging TODO: Documentation. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=71445
Behdad Esfahbod 81bedda5 2015-04-30T13:04:16 New API: hb_buffer_reverse_range()
Behdad Esfahbod 61820bc4 2015-01-26T14:25:52 [API] Add hb_buffer_add_latin1() This is by no ways to promote non-Unicode encodings. This is an entry point that takes Unicode codepoints that happen to all be the first 256 characters and hence fit in 8bit strings. This is useful eg in Chrome where strings that can fit in 8bit are implemented that way, and this avoids copying into UTF-8 or UTF-16. Perhaps we should rename this to hb_buffer_add_codepoints8(). I'm also curious if anyone would be really interested in hb_buffer_add_codepoints16(). Please discuss!
Behdad Esfahbod 976c8f45 2014-07-16T15:34:20 New API: hb_buffer_[sg]et_replacement_codepoint() With this change, we now by default replace broken UTF-8/16/32 bits with U+FFFD. This can be changed by calling new API on the buffer. Previously the replacement value used to be (hb_codepoint_t)-1. Note that hb_buffer_clear_contents() does NOT reset the replacement character. See discussion here: https://github.com/behdad/harfbuzz/commit/6f13b6d62daae4989e3cc2fe4b168e5c59650964 New API: hb_buffer_set_replacement_codepoint() hb_buffer_get_replacement_codepoint()
Behdad Esfahbod bcba8b45 2014-07-16T14:59:04 New API hb_buffer_add_codepoints() Like hb_buffer_add_utf32, but doesn't do any Unicode validation. This is like what hb_buffer_add_utf32 used to be until a couple commits ago.

Behdad Esfahbod 1172dc73 2013-01-07T16:46:37 Rename hb_buffer_clear() to hb_buffer_clear_contents() The previous name was clashing with harfbuzz.old. There are systems that need to link both... Clash-free now again.
Behdad Esfahbod f3064103 2012-11-15T18:39:46 Bunch of independent changes (ouch) API additions: hb_segment_properties_t HB_SEGMENT_PROPERTIES_DEFAULT hb_segment_properties_equal() hb_segment_properties_hash() hb_buffer_set_segment_properties() hb_buffer_get_segment_properties() hb_ot_layout_glyph_class_t hb_shape_plan_t hb_shape_plan_create() hb_shape_plan_create_cached() hb_shape_plan_get_empty() hb_shape_plan_reference() hb_shape_plan_destroy() hb_shape_plan_set_user_data() hb_shape_plan_get_user_data() hb_shape_plan_execute() hb_ot_shape_plan_collect_lookups() API changes: Rename hb_ot_layout_feature_get_lookup_indexes() to hb_ot_layout_feature_get_lookups(). New header file: hb-shape-plan.h And a bunch of prototyped but not implemented stuff. Coming soon. (Tests fail because of the prototypes right now.)
Behdad Esfahbod 3f82f8ff 2012-11-15T18:45:31 Rename hb_buffer_guess_properties() to hb_buffer_guess_segment_properties()
