The unprefixed `script_*` symbols are marked as `skip`, but the
introspection scanner will still warn about them because the annotations
are resolved after parsing the C code.

|
|
|
|
|

Abolish the PANGO_ENABLE_BACKEND and PANGO_ENABLE_ENGINE
defines. All backend-only apis are moved into private
headers, all apis that were engine-only are marked as
deprecated, since engines are.

To make it a bit more explicit that there’s no need to worry about
introspecting them.

macros. Also add the version macros in the docs.

Now shaper is discovered via (previously unused!) font->find_shaper().
I'm keeping that just to allow clients override shaping. Though,
even that I'm not sure we want to keep.
Wraps shaper in PangoEngineShape structs to keep PangoAnalysis API
intact.
Deprecated pango-modules.h and some pango-engine.h. Language modules
are not moved yet.
Wired up PangoFc, PangoWin32, and PangoCoretext shapers.

Variant of pango_shape() that takes the full paragraph text as input.
This is then passed in entirety to HarfBuzz, which would allow certain
cross-run interactions (in Arabic for example).
When combined with upcoming HarfBuzz 0.9.5+, this fixes:
Red Hat Bug 858736 - [Spanish] Stray dotted circle rendered

Bug 356194 – more pango_get_log_attrs problems
* pango/break.c (tailor_break): New function. Simply calls the
script_break() function of the language engine, if any.
* pango/break.c (pango_break): Call pango_default_break()
unconditionally. Call tailor_break() on top of the result to tailor
it using the language engines, if any.
* pango/break.c (tailor_segment): Call tailor_break() on the segment,
and make sure the log_attrs for the first position are not corrupted.
* pango/break.c (pango_get_log_attrs): Call pango_default_break() on
the entire paragraph, and call tailor_segment on each segment.
* pango/pango-engine.h: Update docs about *script_break()'s behavior.

Part of Bug 355782 – Misaligned extents in pango
* pango/pango-layout.c (cluster_width): Rewrite based on
is_cluster_start instead of accessing log_clusters directly. This is
more robust as next_cluster uses that, so the two match now.
* pango/pango-layout.c (update_cluster): Remove the
cluster_start_index parameter and use iter->cluster_start instead.
* pango/pango-layout.c (pango_layout_iter_copy): Fix typo in copying
iter->cluster_width.
* pango/pango-layout.c (pango_layout_iter_get_cluster_extents): Add
an assert to make sure iter->cluster_width is correctly set.
* pango/pango-layout.c (pango_layout_iter_get_char_extents): Remove
assert that was readded above to check more cases.

2006-02-02 Behdad Esfahbod <behdad@gnome.org>
Finish the 'glyph 0' work of this morning:
PANGO_GLYPH_NULL that I introduced is renamed to
PANGO_GLYPH_EMPTY. It means, no rendering should
be performed. The backends however, still return
0 if a glyph is not found. The modules then are
free to replace this 0 glyph with an unknown
character.
* modules/arabic/arabic-fc.c, modules/basic/basic-atsui.c,
modules/basic/basic-fc.c, modules/basic/basic-win32.c,
modules/basic/basic-x.c, modules/hangul/hangul-fc.c,
modules/hebrew/hebrew-fc.c, modules/indic/indic-fc.c,
modules/khmer/khmer-fc.c, modules/syriac/syriac-fc.c,
modules/thai/thai-fc.c, modules/tibetan/tibetan-fc.c,
pango/pangox.c, pango/pangowin32.c:
Adapt to above change. Backends return 0 if glyph not
found.
* pango/fonts.c (pango_font_get_glyph_extents): If font
is not usable (!PANGO_IS_FONT (font)), return the generic
UNKNOWN_GLYPH metrics. This is used when your backends
are misconfigured and you don't find *any* font at all.
* pango/pango-engince.c: Add unknown glyphs in fallback
shaper, instead of empty glyphs.
* pango/shape.c: Call the fall-back shaper if shaper
fails, instead of generating a dummy glyph string ourselves.
* pango/pango-layout.c (imposed_shape, shape_tab): Use
PANGO_GLYPH_EMPTY instead of glyph 0.
* pango/pango-renderer.c (pango_renderer_draw_glyph): No-op on
PANGO_GLYPH_EMPTY instead of glyph 0.
* pango/pangocairo-atsuifont.c, pango/pangocairo-win32font.c,
pango/pangocairo-fcfont.c, pango/pangocairo-font.c,
pango/pangocairo-private.h: install_font returns a boolean now.
* pango/pangocairo-render.c, pango/pangoxft-render.c: Handle font
and hex-box failures more gracefully by drawing a generic
unknown-box glyph.
* pango/pangoft2.c, pango/pangoft2-render.c: Draw the generic
unknown-box glyph here too. For unknown glyphs though, if
the font is TTF (FT_IS_SFNT), use the zero-indexed glyph,
otherwise, draw a box of proper size.

Tue Sep 23 18:03:57 2003 Owen Taylor <otaylor@redhat.com>
* pango/pango-engines.[ch] pango/pango-engines-private.h:
Modules now declare a list of scripts that they cover instead of a
list of code point ranges. Also, there is now a ->covers() virtual
function that allows a module to decide live whether the font
covers a particular codepoint; remove old get_coverage() method.
* pango/pango-fontset.[ch]: Add a foreach() function to
iterate over all the fonts in a fontset (with a true
return stopping iteration).
* pango/pango-context.c: Complete rewrite using script-run
information to improve language tags. Switch to an approach
where we handle one run at a time rather than computing
information for each character individually then later
breaking the result into runs.
* pango/pango-fontset.[ch]: Switch over to using
pango-impl-utils.h.
* modules/basic/basic-x.c pango/pangox-fontmap.c: Adapt to
the change from get_coverage => covers.
* pango/pango-modules.h pango/modules.c: Switch PangoMap
over to being based on script rather than being based
on codepoint. Remove the no longer needed pango_map_get_entry().
* pango/modules.c: Handle new script-based modules.
* pango/pango-fc-fontmap.c pango/pango-win32-fontmap.c
pango/pang-fontmap.[ch]: Add a shape_engine_type field
to PangoFontmapClass, pango_font_map_get_shape_engine_type();
this allows generic code to find a shaper for a particular
fontmap.
* pango/pango-script.[ch]: Add pango_script_get_sample_language(),
pango_language_includes_script(); functions for determining
the relationship between scripts and language.
* tools/gen-script-for-lang.c: Modify to spit out a
useful table.
* pango/pango-script-lang-table.h: Version of table
generated from current fontconfig data.
* pango/pangox.c: Remove complicated code to compute
coverages; no longer useful now that we just have
the basic shaper as a legacy thing.
* modules/*/*.c: Adapt to identifying shape engines
by language range.
* modules/thai/thai-fc.c modules/thai/thai-shaper.[ch]:
Remove now unused "has_glyph" function and XTIS support.
* modules/thai/thai-fc.c: Handle non-Thai characters
as well, since the Thai module now gets spaces,
punctuation, and so forth.

* pango/pango-item.[ch]: Memory management functions for PangoItem.
* pango/*.[ch]: Random constification.
* pango/pangox.c pango/pango-layout.c pango/pango-context.c:
Add an extra_attrs field to PangoItem. Use this to handle underlining
for PangoLayout.
* examples/viewer.c (reload_font): Make paragraphs global
to save the complexity of passing it around all over the place.
* pango/pango-layout.[ch] (pango_layout_context_changed): Add
a function to reset the layout on changes to the layout's
context.
* pango/pangox.c (pango_x_make_matching_xlfd): Prefer bitmap
to scaleable if the discrepancy is < 1 pixel. (Probably not
the ideal criterion.)
* pango/pangox.c (pango_x_font_map_for_display): Fix resolution
computation error.
* pango/pango-layout.c (pango_layout_check_lines): Handle
text with embedded newlines.
* pango/pangox.c (pango_x_render_layout): Fix y to refer
to the top of the layout, not the baseline of the first
line.
* pango/pango-layout.c (process_item): Don't wrap if width is
set to -1.
* Makefile.am configure.in **/*.[ch]: move libpango/ directory
and fix all headers to install under include/pango/

* libpango/pango-types.h: Conditionally define G_N_ELEMENTS() when
using glib-1.3.
* modules/basic/basic.c modules/hangul/hangul.c modules/tamil/tamil.c:
Replace MEMBERS() with G_N_ELEMENTS().
* libpango/pango-engine.h: Added a get_coverage() function
to the PangoEngineShape vtable.
* modules/basic/basic.c modules/hangul/hangul.c modules/tamil/tamil.c:
Added get_coverage() functions. The basic.c one is incredibly
inefficient (but caching may make that matter that much).
The Hangul one needs checking.

* libpango/pango-*.h: The great header file reorganization.
Split up roughtly by objects.
* libpango/pango-font.h libpango/fonts.h: Add generic
font-loading and listing interfaces.
* libpango/pangox.c: Implement font-listing/loading interfaces
for X.
* libpango/pango-context.[ch]: Flesh out context structure.
Add appropriate accesors, font loading-methods, etc.
* libpango/pango-coverage.[ch]: Coverage map objects.
* examples/viewer.c: First stab at adding font-selection. Majorly
deficient for the moment until we add font lists and fallbacks
based on coverage maps.
