Out of curiosity, what does smex do that counsel-M-x doesn't?

[kaushalmodi]

@PythonNut counsel misses the command ranking that smex does. For example, with smex, when you call counsel-M-x, you will see the last used command top most in the list. Without smex, you will just get an alphabetically sorted list.

@abo-abo - Is there any particular reason you removed :group from the defcustom function calls?

[tumashu]

it's excellent! suggest merge

[Trevoke]

I would be very grateful if this got merged.

@nonsequitur Hello?

[Trevoke]

I just took a (granted fairly quick) look through the gists, inf-ruby and this repo, and I see no activity from @nonsequitur in quite a long time. I don't know if he or she is alive, frankly. We might need to create a fork for this code so we can continue maintaining it.

Maybe we shouldn't jump the shark, though. I know nothing of this person.

[kaushalmodi]

@Trevoke Well, @nonsequitur last had activity last July, and this issue was opened in April last year (16 months ago). Looks like the maintainer is somehow not interested in this.

Consider counsel-M-x?

You can use flx with ivy as per this config

[Trevoke]

Sure, I can try it. Where can I find counsel-M-x ? I tried installing
counsel through the package manager, maybe that's not good enough?

@Trevoke Installing the counsel package is all you need. Then M-x counsel-M-x should work.

[asmeurer]

I just tried counsel, but I was disappointed that the default completions when I type M-x are ordered alphabetically, instead of by most recently used. Maybe I need to configure something?

[Trevoke]

If you bind counsel-M-x to M-x then you should be fine:

[Trevoke]

@kaushalmodi Got it. I ran into an error because I didn't have swiper installed.

[tumashu]

@asmeurer Install smex , counsel-M-x will use it to sort will recent used

[asmeurer]

Ah. I had originally left smex enabled, but got some error about it (I'll have to check what it was on my other computer tomorrow, some undefined variable error I think), so I disabled it.

[kaushalmodi]

@Trevoke Yup, installing it using the in-built package manager would have done it automatically for you. From counsel.el:

;; Package-Requires: ((emacs "24.3") (swiper "0.8.0"))

[asmeurer]

Ah. I had originally left smex enabled, but got some error about it (I'll have to check what it was on my other computer tomorrow, some undefined variable error I think), so I disabled it.

"Symbol's value as variable is void: smex-initialized-p"

If I manually execute (setq smex-initalized-p t) it works (and things are in the right order).

[asmeurer]

Oh, I see. I've been using the branch from #12. CC @haxney I guess removing smex-initialize in that PR breaks counsel compatibility (and it looks like I already noticed this two years ago smh).

[joca-bt]

@nonsequitur please merge this, it's very helpful!

[tumashu]

In my opinion, if you are a ivy user, you should use counsel-M-x instead of smex.
