Khaled Hosny c2442c90d6 [doc] Add placeholder since version for new flag 2019-03-12 01:10:52 +02:00
Eric Muller 30d7c40f8c Add a flag to hb_buffer_t to prevent the insertion of dotted circles on incorrect character sequences.
Current behavior unchanged if this flag is not set (and it isn't by default).

Behdad Esfahbod 3b7aa651b4 [docs] Improve UNSAFE_TO_BREAK docs 2018-02-09 15:43:20 -06:00
bungeman 671f0a7733 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.

fanc999 48a9406839 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.

Chun-wei Fan 835bbdc7c9 Public headers: Decorate public symbols with HB_EXTERN

Behdad Esfahbod 61820bc4ca [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 976c8f4552 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:

  hb_buffer_set_replacement_codepoint()
  hb_buffer_get_replacement_codepoint()
