Extended English Input

Extended English Input (EEI) is an IBus input method that I wrote primarily for my personal use, because I was sick of having no good way to input emojis and math symbols into most applications. It's a little bit like a faster and much smaller IBus typing booster that does way less.

Installation

Assuming you are set up to compile both C and Rust, installation should be as simple as:

git clone git@github.com:Mindful/eei.git
./install.sh

Advanced installation

Further instruction can be found at INSTALL

Usage

Then, to actually use your new input method:

ibus restart
ibus engine eei

ctrl+e opens the emoji/symbol lookup table. ctrl+w while in the middle of typing a word opens autocomplete for that word.

Generating dictionary data

Binary dictionary data is included in the git repository, so this step is not necessary unless you want to rebuild or modify the dictionary data.

First, download the en_US hunspell dictionary data from http://wordlist.aspell.net/dicts/

sudo apt-get install hunspell-tools
wget http://downloads.sourceforge.net/wordlist/hunspell-en_US-2020.12.07.zip
unzip -o hunspell-en_US-2020.12.07.zip
unmunch en_US.dic en_US.aff > hunspell_US.txt

Then get the word frequency data

wget https://norvig.com/ngrams/count_1w.txt

Finally, run the preprocessing script

cd src/predict
cargo run --package preproc --bin preproc

This will generate dictionary.fst, shortcodes.fst and symbols.bin.

IBus resources

Documentation for IBus is pretty poor, so much of the code here is based off of the below repos:

• ibus-tmpl
• ibus-unikey
• ibusenginesimple
