ibus-typing-booster

Faster typing by context sensitive completion.

Introduction

Ibus-typing-booster is a completion input method to speedup typing.

The project was started in 2010 for Fedora 15. The original purpose was to make typing of
Indic languages easier and faster by providing completion and spell checking suggestions.

Originally it was forked from ibus-table whose developer was Yu Yuwei acevery@gmail.com,
with contributions from Caius “kaio” Chance me@kaio.net.

Since then ibus-typing-booster has been improved to support many other languages as well
(most languages except Chinese and Japanese are supported).

Recently the capapility to type different languages at the same time without having to
switch between languages has been added.

Developers:
  
  • Mike FABIAN mfabian@redhat.com
  • Anish Patil anish.developer@gmail.com

Features
  
  • Context sensitive completions.
  • Learns from user input.
  • Can be trained by supplying files containing typical user input.
  • If available, hunspell and hunspell dictionaries will also be used to provide not only
    completion but also spellchecking suggestions (But ibus-typing-booster works also
    without hunspell by learning only from user input).
  • Can be used with any keyboard layout.
  • Almost all input methods supplied by libm17n are supported (including the inscript2
    input methods).
  • Several input methods and languages can be used at the same time without switching.
  • Predicts Unicode symbols and emoji as well.
