The table in which (un-)supported editors are listed mentions Eclipse as unsupported on OS X (and Windows). I can confirm that ligatures work in Eclipse Oxygen (4.7.0), at least using OS X 10.12.5. Note that I did not had to tweak anything other than selecting Fira Code as the font.


You might want to update the documentation.
thanks!
SOME Ligatures also work on Windows. WWW, *, .., .., Equality signs work.
Greater/smaller than, Arrows, XML Tag stuff etc. don't.
Incomplete lists, I haven't had the time to test all the ligatures
Interesting, I鈥檒l have to check. Thanks @MartyBeGood. It might mean they got them working but syntax breaks some sequences
@tonsky, in the last release of Eclipse (Photon) all ligatures seem to work (for instance, now <= ligature works).
However, they fail randomly (at least in Windows). For example:
It's an annoying bug, but I have not found any opened issue.

None of ligatures work for me in eclipse oxygen 4.7.3a (Most up to date version when writing this)
The latest version is Eclipse Photon (4.8), released on June. However, it is not in Fedora (and the most distros) repositories yet, but you can download from the official web page: https://www.eclipse.org/downloads/packages/ (I have tested it on Windows and works as described).
