For those who may not know, the IPA (international phonetics alphabet) is widely used for writing out how words are spoken. It's very useful for linguists writing research papers, and for people looking to learn new languages!
As I wasn't satisfied with most IPA keyboards available, and wanted something that integrated well with fcitx, which I already have to use for japanese input, I re-implemented parts of the SIL IPA keyboard . It's not a one-to-one recreation (yet), because I needed somthing now rather than later, and took some shortcuts to put in all the features I personally needed, but it should be good enough for doing broad transcription of RP English. It should also be fairly trivial to hack in support for most character combinations.
i know i've wanted something like this for a while. i really didn't want to have to figure out how to get the existing keyman keyboard layout to work on linux, because fcitx works fine for all my other input needs, and i already knew how fcitx worked as i made an addon to get on-screen keyboards to work with it a while back...
as i know not many people would dare venture in the world of fcitx addons, due to the quite horrendous state the documentation is in... so if i wasn't gonna do it, likely no-one else was, so i did it! and shared it with everyone, because the worse that could happen is that someone helps me make it better!
