Doesn't work at all in Emacs

[alphapapa]

I know Emacs doesn't support ligatures, but I was still hoping to use Fira Code in Emacs since it has less line spacing or lower line height than Fira Mono. But this is what I see when I use Fira Code in Emacs:

[kirang89]

That's weird. This is how Fira Code looks in my setup:

[alphapapa]

Hm, I just discovered that it also displays with this crazy character spacing in the KDE font manager. It's very strange, because I've installed a lot of different programming fonts, and none of them have any kind of problems like this, including Fira Mono.

I also tried using the 0.5 release, in both OTF and TTF formats, and they all have the same problem. This is very weird!

And to make it even weirder: When I open the fonts in the KDE Font Viewer, they display fine. But when I install them, they have the problem. And not a single other font I have has this problem.

And for the icing on the cake: When I install it but "disable" it in the KDE Font Manager, the preview within the Font Manager displays correctly. But when I reenable the font, the preview displays with the problem again.

What about Fira Mono? Does it display okay?

Yes, it works fine.

[emmanueltouzery]

I also see the same problem with Fira Code 0.6 in emacs while Fira Mono works fine. GNU Emacs 24.5.1, Fedora 22.

[hlieberman]

Yup, can confirm this is a (very strange) bug on emacs24 on Debian.

[HiCodin]

same issue for me as well. emacs 24.5.1 on Ubuntu 14.04

[andrelaszlo]

Great work on the font! Too bad it doesn't work in Emacs - it would have looked nice.
Since this seems to be an Emacs problem more than a problem with this font, maybe you can close this issue?

See this: http://emacs.stackexchange.com/questions/9586/otf-ligature-support-in-emacs

[tonsky]

@andrelaszlo are you using the latest version? It should be identical by all means to Fira Mono (I’m using the same source and the same build software), and Fira Mono was reported to work fine. Can you check please with 1.102?

[andrelaszlo]

Sorry, my bad. I was using the ancient version available in AUR.

Ligatures still don't work, but otherwise it looks fine (Emacs 24.5.1, FiraCode 1.102):

[HiCodin]

same with @andrelaszlo . font works fine now but ligatures still are not working.

[andrelaszlo]

I think that ligatures are still missing from Emacs, according to the link in my first post. The double character width thing from the screenshot is fixed however, leaving us with a usable (and useful) font.

Ligatures are rendered correctly in other applications, so I guess we're stuck with the fix suggested in the README.

[lf94]

Not even the suggested fix works. I'm on Emacs-snapshot. It would be nice if it did! :)

[jethrokuan]

Ligatures still don't work for me either. Looks pretty enough now, though ligatures would be great.

[lf94]

This is not a FiraCode issue but an Emacs issue really. It's too bad Emacs isn't on a social coding platform because I would contact them then. If someone could hit up the mailing list that would be greatly appreciated.

If someone could hit up the mailing list that would be greatly appreciated.

What should one hit it with?

[lf94]

Ligature support, maybe? I'm not entirely sure what this feature is called.

[dgutov]

Yes, I'm not sure how to phrase it either. But you're probably looking for M-x report-emacs-bug.

[jethrokuan]

Someone in the clojure slack channel mentioned that the osx build for emacs
has been patched with ligature support such that Fira Code works for him
out of the box, but I can't find any mention of it anywhere. Unless the
changeset is small and isolated it's unlikely vanilla emacs will introduce
ligature support anytime soon, given that they're focusing on eliminating
bugs right now

I was using the railway-cat build on OSX El Capitan 10.11.2, and it worked
beautifully with ligatures and this font.

However since 10.11.3 I can no longer build it.

My point is that there is support in the railway-cat build, following the
instructions included.

I don't know if this is the same thing of course, but @RadicalZephyr recently posted a patch on this issue tracker: #42 (comment)

It's mentioned at the bottom of the Setting up Emacs wiki page.

@xsyn did you get any sluggishness, compared with the vanilla OS X build? I'd love to use that build, because of the ligature support and better OS X integration, but I'm getting a very unresponsive UI, especially (but not only) when scrolling.

I mean, just scroll around a file, or keep something like + (in normal mode) pressed on auto-repeat, and you'll see the scrolling jump around quite a bit, not to mention the cursor disappearing.

Can you suggest any tweak or setting to make it perform better? What version were you using?

[xsyn]

I found that turning off progressive scrolling made a huge difference for me:

(setq mouse-wheel-progressive-speed nil)

[ninrod]

[felipebalbi]

I have the same issue here. Here's with Fira Mono:

And here's the same with Fira Code:

I've opened emacs with emacs -Q to make sure this wasn't caused by some problem on my configuration. I've tried with sizes 10 to 15 and it all looks the same. This is with latest Fira Code 2 installed via Arch package, emacs 26.3
