* Trick g-ir-scannerMatthias Clasen2021-02-151-3/+4
| | | | | | | | | g-ir-scanner's handling of #defines is really rudimentary, so we have to trick it to pick up PANGO_ATTR_TO_TEXT_END as a constant with value 0, and then override the value with an annotation. See https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/369
* docs: Remove references to gdk_pango_context_get_for_screendocs-tweakMatthias Clasen2021-02-112-4/+2
| | | | Remove references to a function that no longer exists in gtk.
* Fix pango_font_describe for Emoji fontsMatthias Clasen2021-01-241-1/+18
| | | | | | | | | | | We are using the size from the FcPattern. For scalable bitmap fonts, this has been scaled to match the requested pixel size. To make a font description that can be turned back into a FcPattern and roundtrip successfully, we need to undo that scaling. Thankfully, fontconfig leaves the pixelsizefixupfactor in the pattern, so it is easy to do. Fixes: #530

| * Avoid overflow when updating attr listsattr-list-overflowMatthias Clasen2021-01-231-1/+4
| | | | | | | | | | | | | | | | | | | | | | Avoid overflow when updating the end_index of attributes in pango_attr_list_update. This is a real risk, because end_index is commonly set to G_MAXUINT to mean 'until the very end'. Test included. Fixes: #455
| * Add some preconditionsMatthias Clasen2021-01-231-0/+4
| | | | | | | | | | The arguments to pango_attr_list_update are ints, but negative numbers don't make sense here.
* | Don't promise too muchMatthias Clasen2021-01-231-3/+2

* meson: add harfbuzz gobject dependencyStéphane Cerveau2021-01-131-1/+6

| * fontconfig: Try harder to find a default faceregular-faceMatthias Clasen2020-11-061-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | Fonts are amazing, and not in a good way. My system has fonts with 0, 1, 2 "Regular" faces. It also has fonts where the "Regular" face is, in fact, bold. So, we need to work even harder to return a reasonable face when asked about the default. We already make a determination of faces that we consider 'regular' when we create the faces initially. Just keep that information for later reuse.

| * fontconfig: Try harder to return a default faceMatthias Clasen2020-11-051-3/+7
| | | | | | | | | | | | | | | | | | pango_font_family_get_face() is documented as nullable, so we are technically within our rights to return NULL, but that is unexpected when passing NULL to get the default face, and the family has faces. So, try a little harder by returning the first face if we don't find a face with the name "Regular".
* | ft2, xft: Write out the full type of the SubstituteFuncwip/issue510Simon McVittie2020-11-052-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | If the SubstituteFunc used for the now-deprecated set_default_substitute functions is an alias for PangoFcSubstituteFunc, GObject-Introspection doesn't realise it's a function pointer, and doesn't flag the user data and destroy-notify arguments as such. This results in bindings like PyGI thinking that they are entirely separate arguments, which is an introspection API break (and probably not something that can practically be called any more).

* | meson: Change introspection option to yielding featureXavier Claessens2020-09-301-1/+2
|/ | | | | | | Yielding option means that if pango is built as a subproject, it will take the value of that option from the parent project (e.g. gst-build). For that to work it must be of the same type, which is "feature" instead of "boolean" in all GStreamer modules.
* Revert "meson: Change introspection option to yielding feature"Matthias Clasen2020-09-301-2/+1
| | | | | | | This reverts commit 82cfabbabaade239beb26136cb28c98156552ea5. This change broke GTK ci, and it takes more work to fix it than I can invest atm. We can try again when GTK is ready for it.
* Skip a pangofc accessorEmmanuele Bassi2020-09-301-1/+1
| | | | | | The handwritten fontconfig introspection data does not cover all types, and even if it did, it wouldn't know how to handle their ownership because fontconfig is not a GObject-based API.

| | | | | | | | | | | | | | | | | | | | | | | | The last character of Emoji keycap sequences, 0x20E3, has a vertical orientation of U, according to Unicode. This unfortunately makes the width iter frequently break such sequences into multiple items, preventing them from being rendered as expected. Fix this by ignoring width changes inside Emoji sequences. Fixes: #502

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This broke when PangoAttrIterator was changed to use an array for the stack of current attributes, in dec6c0868ef2c36. We were not always walking the array in the right order. The first attribute to check is at the *end* of the array. This showed up as misrendering in epsilon_0 example in gtk3-demo's text view markup demo. Test included.

I ran into this when executing tests of recent LibreOffice master with ASan on Fedora 32 (with pango-1.44.7-2.fc32.x86_64), where one of the tests renders various dialogs with a Tamil localization and failed with > ==97247==ERROR: AddressSanitizer: SEGV on unknown address 0x60b000210006 (pc 0x7fd6c5b22b54 bp 0x61d0004b4150 sp 0x7fff107a0d18 T0) > ==97247==The signal is caused by a READ memory access. > #0 in g_utf8_get_char at ../glib/gutf8.c:319:37 (/lib64/libglib-2.0.so.0 +0x85b54) > #1 in break_indic at ../pango/break-indic.c:119:17 (/lib64/libpango-1.0.so.0 +0x1076d) > #2 in break_script at ../pango/break.c:1896:7 (/lib64/libpango-1.0.so.0 +0x1076d) > #3 in tailor_break at ../pango/break.c:1606:9 (/lib64/libpango-1.0.so.0 +0x147db) > #4 in pango_tailor_break at ../pango/break.c:1774:7 (/lib64/libpango-1.0.so.0 +0x147db) > #5 in get_items_log_attrs at ../pango/pango-layout.c:4032:7 (/lib64/libpango-1.0.so.0 +0x2729c) > #6 in pango_layout_check_lines at ../pango/pango-layout.c:4289:7 (/lib64/libpango-1.0.so.0 +0x2729c) > #7 in pango_layout_get_extents_internal at ../pango/pango-layout.c:2623:3 (/lib64/libpango-1.0.so.0 +0x29068) > #8 in gtk_label_get_measuring_layout at /usr/src/debug/gtk3-3.24.22-1.fc32.x86_64/gtk/gtklabel.c:3376:3 (/lib64/libgtk-3.so.0 +0x2454d0) [...] From some debugging, it smells like `pango_layout_check_lines` calls `pango_itemize_with_base_dir` to compute `state.items` that are relative to the beginning of `layout->text`, but then passes `state.items` together with the offset'ed `start` into `get_items_log_attrs`, so that the latter misinterpreted the items' locations relative to the offset'ed start. Just adding g_assert (item->offset <= length); g_assert (item->length <= length - item->offset); to the original `get_items_log_attrs` would make various tests in the `meson test` suite fail, but which pass again with the complete fix, matching the above speculation.
