== Summary ==
IBus 1.5.25 will use `transfiletriggerin` script to generate the cache
file instead of `posttrans` script in each engine package, support the
include directive in the user compose file, IBus compose feature will
follow the GTK4 compose pre-edit style, the emoji shortcut key will be
changed to `Ctrl-period`, IBus GTK4 module will proceed the key events
synchronistically to follow GTK4 specification.
== Owner ==
* Name: [[User:Fujiwara|Takao Fujiwara]]
* Email: fujiwara [at] redhat [dot] com
== Detailed Description ==
* Each IBus language engine has run `posttrans` script to run `ibus
write-cache` to cache their component files in
/usr/share/ibus/component whenever the package is installed but `ibus
write-cache` will moved to `transfiletriggerin` script in IBus core
package and the script will be executed only one time per the Fedora
installation.
* IBus compose file will support the include directive in the user
compose file ($XDG_CONFIG_HOME/ibus/Compose,
$XDG_CONFIG_HOME/gtk-3.0/Compose or $HOME/.XCompose)
* IBus compose feature will follow the
[https://blog.gtk.org/2021/03/24/input-revisited/ GTK4 compose
pre-edit style].
* IBus emoji shortcut key is `Ctrl-Shift-e` and it will be changed to
`Ctrl-period` to follow the latest GTK while it's customizable with
`ibus-setup` utility.
* IBus GTK3 module proceeds the key events asynchronistically because
some langauge engines spend much time to compose key events and D-Bus
process could causes a timeout but now GTK4 does not allow the async
events and IBus GTK4 module will proceed the key events
synchronistically.
== Feedback ==
* Only one `transfiletriggerin` script is much simpler than many
`posttrans` scripts.
== Benefit to Fedora ==
Users can use the include directive in their compose files. IBus GTK4
module can send the application specific keys of Backspace, Enter to
the target application to follow GTK4 specification,
== Scope ==
* Proposal owners: Update SPEC file to add `transfiletriggerin`
script. Update libibus.so to enhance compose feature. Update
org.freedesktop.ibus.gschema.xml for emoji shortcut key. Update
libim-ibus.so to fix IBus sync process.
* Other developers: Update SPEC files to delete `posttrans` script.
* Release engineering: [https://pagure.io/releng/issue/10184 #10184]
* Policies and guidelines: N/A
* Trademark approval: N/A
* Alignment with Objectives:
== Upgrade/compatibility impact ==
We should avoid regressions with `transfiletriggerin` script in the
Fedora installation.
== How To Test ==
# Install ibus and the language engine packages
# `ibus read-cache --system` shows the installed engines.
# `rpm -q --scripts` does not show `ibus write-cache` in engine packages
# `rpm -q --filetriggers` shows `ibus write-cache` in ibus package
# Write the line of 'include "%H/foo.compose"' in your $HOME/.XCompose
and some compose sequences in $HOME/foo.compose
# Run `gnome-control-center keyboard` and configure some IBus language
engines besides XKB engines, likes ibus-hangul, ibus-typing-booster
# Enable an XKB engine with Super-space or clicking of the keyboard
idicator in GNOME
# Launch gedit
# Confirm your compose sequences in $HOME/foo.compose is reflected
# Confirm compose preedit is short
# Run `gnome-control-center keyboard` and configure some IBus language
engines besides XKB engines, likes ibus-hangul, ibus-typing-booster
# Enable an XKB engine with Super-space or clicking of the keyboard
idicator in GNOME
# Launch gedit
# Type Ctrl-period
# Confirm emoji pre-edit and lookup table is available
# Install gtk4-devel
# Run `env GTK_IM_MODULE=ibus gtk4-demo`
# Backspace, Enter keys works
== User Experience ==
The emoji shortcut key is changed if users do not customize it but
they can customize it with ibus-setup utility.
== Dependencies ==
ibus-anthy, ibus-chewing, ibus-hangul, ibus-input-pad, ibus-kkc,
ibus-libpinyin, ibus-rawcode, ibus-sayura, ibus-skk, ibus-table,
ibus-typing-booster, mozc (`posttrans` script has already been
deleted in each engine package in Fedora rawhide.)
== Contingency Plan ==
* Contingency mechanism: Revert the change to IBus.
* Contingency deadline: Beta release
* Blocks release? No
== Documentation ==
TBD
