Ctrl+H committed the syllable being composed and opened an empty search,
so converting 한 meant typing it twice; the pending syllable now seeds the
query. Backspace on an already empty search ended it and then reached the
application, deleting a character; it now only ends the search.
Enter with a pending syllable committed it and stopped there, so a chat
message needed Enter twice; Korean input methods commit and pass the key
on. Japanese keeps consuming the key that confirms a reading or a chosen
candidate, as Japanese input methods do.
Clicking elsewhere, changing focus, or any client reset dropped the
composition in the GTK module and IBus (only XIM ResetIC handed it
back), so typing 안녕 and clicking Send lost 녕. The engine now returns
the pending text — a moved-to candidate first, as Enter would — on
Keyreset and Keyrelease; the GTK module asks for it before closing on
focus-out and commits it, IBus commits it on FocusOut, Reset and a
switch to a password field, and XIM commits it on focus loss and hands
it back on ResetIC without a separate capability probe.
Hiragana spelled out 42 doubled syllables (kka, ssha, ttsu, ...) and so
knew none it did not list: matcha, baggu and beddo came out as ma-tc-ha,
ba-gg-u. Katakana already used the engine's small-tsu rule for a few
doubles. Both maps now list every doubled consonant but n, plus tch, and
hiragana gains di, che and fa/fi/fe/fo like katakana.
Ctrl+E during an emoji search, Ctrl+H during a hanja search, or either
during the other search dropped the typed query, while every other
Ctrl key committed it as the README says. Escape is the way to cancel;
the search keys now commit the shown text like a language switch.
Up, Down, PageUp and PageDown with a composition pending and nothing to
move through returned the key uneaten but left the text pending, so the
client moved its cursor and reset the context: the pending Korean
syllable vanished, where Left or Home would have committed it. Let them
fall through to the special-key path that commits and passes the key.
At the limit the key that did not fit was handed back to the client as
plain ASCII, so a long Japanese reading ended in a Latin letter, and a
pending romaji consonant was flushed as ASCII with it (…あka for か).
Commit the completed kana, keep the pending syllable, and transliterate
the key as usual; other languages commit and go on the same way.
server_test, ibus_test and xim_adapter_test each ran their own copy of
the same alt loop that stands in for imthread, and two of them had
private checkstr/checkenginepreedit variants. test_util.c now provides
Pump (trace, optional hold on a chosen op, stop) in its own proc so a
test may block in socket I/O while the engine runs, and test.h declares
the engine hooks once; every .c includes dat.h and fn.h itself as the
rest of the tree does. server_test's three copies of fixture setup and
teardown became serverbegin/serverend.
ko_test and vi_test replayed keys with private copies of transstr's
loop, and test_util reimplemented the shown preedit; the engine exports
impre(Im*, Str*) and transstr() instead, so a change to composition
rules is one edit.
mapget and maplookup were one trie probe with two predicates; mapmatch
returns the match kind and mapget is its exact case. movedelta is a
switch. searchkey's modifier test was unreachable behind transition's,
searchlang's Alt/Super test behind both callers' earlier returns, and
picksearch's range check behind numberedkouho. Korean key folding runs
once at the top of transition. commit() on an empty preedit is a no-op,
so the Ctrl branch and startsearch lose their haspre guards and repeated
commit/reset pairs. Ctrl+language inside a search now commits the shown
query as it does elsewhere instead of dropping it. Language ids are
documented as the Ctrl codes they are; Im parameters no longer shadow
the file's Im.
Every key copied the whole Im and Search rune by rune, compared them
after the transition, and combined the answer with 'eaten', a commit
count that is always zero, and a force flag for caret and owner changes,
while redraw() kept a separate 'visible' bit to know when to send an
empty popup. redraw() now compares the snapshot with the last one sent
and treats two empty popups as equal, so imhandlekey just ends in
redraw(). keystroke() was only a test entry point and moves there.
The dictionary thread ran in imthread's own proc, so a lookup could
only start once the engine blocked, and it was a trie probe anyway; the
emoji and Hanja searches already called dictlookup directly. The
request/result channels, sequence numbers, staleness checks and the
second draw per Japanese key are gone; dictqjp fills the candidates
in place. Emit.dict and Lang.dictq only ever triggered lookups for
Vietnamese, which has no dictionary. dictlookup(Lang*, key, out, max)
returns the count. The Hanja lookup no longer pre-checks for a single
syllable; a reading either has an entry or it does not.
For Vietnamese the preedit is the map key ('as', 'oong'); only the popup
and the commit path looked it up. Clients with inline preedit therefore
showed 'as' while Enter committed 'á'. impre() now maps once for every
reader, and snapshot() no longer maps a second time.
The hash map served a single exact-match lookup that the trie already
answers, at the price of a second container, a second file loader with
its own drift, and a Str-to-UTF-8 conversion on every chain probe. The
files are small (kanji.dict is 7.5k lines), so the trie holds both.
trieopen validates keys and each space-separated value word against Str
and reports path:line; trielookup takes the Str every caller holds and
treats a nil trie as an unloaded map; trienew/trieput exist for tests.
The overflow guards on growth, Trie.root (always 0) and the per-language
init loop written twice are gone.
Avoid reading inactive Str storage when deciding whether to publish a redraw. Keep the focused engine suite compact by retaining one case for each page, navigation, and empty-result invariant.
Add table-driven dictionary miss and language-switch state coverage, regress stale candidates after backspace, and clear them before dictionary refresh. Keep IPC and runtime-created file checks outside the unit runner.
