* Update cdict
* scripts/subst_of_compose.py: Compute substitutions
from compose mappings. They are used when building dictionaries.
* Add substitutions compose data
* Better suggestion with diacritics
This improves the suggestions for words that contain diacritics and
uppercase letters.
This works by stripping diacritics both when building the dictionaries
(using word aliases added in cdict: https://github.com/Julow/cdict/pull/3)
and during lookup. Cdict then takes care of resolving the correct word.
The substitutions are generated using mappings from `fn`, `shift` and
all the `accent_*` modifiers into srcs/compose/substitutions.json
This can be updated easily when more mappings are added.
* Refactor: Implement the space key as an editing action
The space key is no longer a CHAR key but now an EDITING key. This
allows changing the behavior of the space bar while allowing custom
layout users to define a key outputing a space as before.
KeyModifier and ComposeKey are updated to treat the space key as before.
* Enter the best suggestion when the space bar is pressed
* Refactor: Implement backspace as an editing action
* Undo suggestion when delete is pressed
The delete key (backspace internally) undoes the suggestion if the last
action done was entering the suggestion with either the space bar or the
candidates view.
* Add an option to enable space bar autocomplete
This option is off by default. Undoing a completion with backspace works
in any case.
* Refactor: Track selection emptyness in CurrentlyTypedWord
This removes an expensive RPC call.
Encoding errors in the compose data compiler due to:
- 'UTF-16' adds a BOM, use 'UTF-16-LE' instead
- 'str.encode' returns a byte array, use 'array' to have a 16-bit char
array.
Change the compose state machine definition to allow final states that
are wider than 16-bits.
This increases the number of sequences that can be used from
en_US_UTF_8_Compose.pre from 2013 to 2043 (of 3201).
Thanks to the previous commit, a modifier key can now be more complex
than just a KeyValue.Modifier. This allows a more elegant implementation
of the compose key, that could be taken as a base for other features
(eg. unicode hex entry, hangul)
The COMPOSE_PENDING modifier is removed as keys of kind Compose_pending
can act as a modifier. This has the advantage of highlighting the key
that was last pressed in the sequence.
Rules are added to Pointers: Non-special but latchable keys must clear
latches and cannot be locked with a long press. These rules were not
needed before but were intended.
compile.py implements a parser for X11's Compose.pre files. A lot of
code is necessary to interpret character names but thanksfully, the name
of most characters is contained in the file.
The state machine is compiled into two char arrays which unfortunately
requires an expensive initialisation and allocation.
The COMPOSE_PENDING modifier indicate whether a compose sequence is in
progress. The new key of kind Compose_pending sets the current state of
the sequence.
The compose sequences are compiled into a state machine by a python
script into a compact encoding.
The state of the pending compose is determined by the index of a state.
