On platforms like NixOS, the libX11 installation prefix may differ from /usr/share,
breaking the hardcoded placeholders. Let’s re-use the X11 path definition from imcontextsimple.
Our compose table format is still limited to 16bit
values for keysyms, but what we see in key events
can be 32bit values, and we treat them as such now.
Fixes: #4149
Make gtk_check_algorithmically take a GString
for the result. This is in preparation for allowing
multi-character results here, in the future.
Update all callers.
Apply heuristics to avoid breaking users existing configurations
with the change to not always add the default sequences.
If we find a cache that was generated before 4.4, and the Compose
file does not have an include, and doesn't contain so many sequences
that it is probably a copy of the system one, we take steps to keep
things working, and thell the user about it.
All tables use the compact format now, and we generate
caches in that format too. Bump the cache version to 3
for this.
Replace the python script for generating the builtin table
by a small C program using the same code to generate the data
for the builtin table. This drops the restriction on only
generating a single character in the builtin sequences.
Keep the list of composetables private to GtkIMContextSimple,
and just have an api that creates new GtkComposeTables, either
from a file or from data.
Update tests to use the new api.
Keep string values in the table, and return them
from the check function. This commit temporarily
disables the table caching, since the cache format
does not handle string values yet.
Fixes: #186
Make it possible for gtk_compose_table_check to return
a string instead of just a single Unicode character.
Currently, we only ever return strings holding a single
character, still.
Otherwise gcc complains when we use these as arguments to g_new() on
32bit architectures with:
