With Hydra Version 0.14.0 from GNU Elpa, the first example hydra
(given in the readme and in the commentary at the beginning of
hydra.el) does not work. I am on Emacs 25.2.

Steps (with the Hydra package from GNU Elpa installed by the Emacs
package manager):

0. $ emacs -Q

1. M-x package-initialize RET

2. In *scratch* type the example code from the readme:

(defhydra hydra-zoom (global-map "<f2>")
  "zoom"
  ("g" text-scale-increase "in")
  ("l" text-scale-decrease "out"))

3. C-x C-e to evaluate it

4. Hit F2 to run it

Expected behaviour:

A prompt is displayed listing `g' and `l' as possible keys;
pressing 'g' or `l' changes the font size; pressing any other key
exits the hydra.

Observed behaviour:

No prompt is displayed. Only "f2-" is displayed in the echo area.
Pressing `g' or `l' changes font size as expected and _after_
pressing either `g' or `l' at least once, a hydra prompt is
displayed and subsequently pressing any other key exits the hydra
as expected. However, if a key other than `g' of `l' is pressed
before either `g' or `l' is pressed an error message is displayed.
E.g. pressing `n' produces

  <f2> n is undefined

After the error message is printed, text typed in the buffer at
point is coloured red. [Presumably text properties or an overlay
that was meant to go in the minibuffer were applied at point.]

Can't reproduce with:

1. Remove ~/.emacs.d/elpa/hydra
2. Start emacs-25.2 -Q
3. Install hydra
4. Paste the code you mentioned.

Everything still works.

regards,

I see exactly the same as the OP.  Also with Emacs 24 btw.  I didn't
reinstall or something like that, I just loaded the files from emacs -Q.


Michael.

I see the problem with

  24.4
  24.5
  25.2
  25.3
  Master (3a09343eabaa751e7d40f0a21af5c63427d9a850)

(I didn't test 25.1.), however the problem is subtly different in
24.4 and 24.5 -- after trying to run the hydra and entering an
undefined key, text at point in the initial buffer is not coloured
red.

Please try to reproduce with my steps (especially emacs -Q and
remove/reinstall). There's likely no reason for this code to stop
working other than byte-compilation or config bug: it's worked fine
for 2 months without anyone else complaining.

If I can't reproduce it on my side, I can't do much.

I reproduced this with a newly created user on my Debian computer where
I installed hydra from Gnu Elpa, loaded the files, and tried the recipe.

As far as I understand the definition of `defhydra', the example won't
do what the OP expects unless you additionally eval

  (global-set-key [f2] 'hydra-zoom/body)

Without that, the hydra hinting kicks in only after you have hit another
hydra key after hitting the prefix key.


Michael.

Indeed. When I asked about this on the Emacs Help list a few days
ago, Marcin Borkowski pointed that out, and indeed, as I mentioned
there, following this suggestion I tried:

  (defhydra hydra-zoom ()
    "zoom"
    ("g" text-scale-increase "in")
    ("l" text-scale-decrease "out"))

  (global-set-key (kbd "<f2>") 'hydra-zoom/body)

and this does work just fine. :)

Sorry. I should have mentioned that in this bug report.

So this bug report is about the

  (defhydra hydra-zoom (global-map "<f2>") ... )

form not working and/or about the doc where this is used as the
first example.

Hello Oleh,

Thanks for responding.

I just tried your steps above, but the problem persists.

1. I checked my ~/.emacs.d/elpa/ directory and saw there the hydra
package in ~/.emacs.d/elpa//hydra-0.14.0.

2. I went into the Emacs package manager and deleted the hydra
package.

3. I exited Emacs.

4. I checked my ~/.emacs.d/elpa/ directory and the hydra-0.14.0
directory was gone.

5. I ran Emacs -Q.

6. M-x list-packages RET

7. I went to the hydra package in the list and marked it for
installation. Then I issued the `x' command to install it.

8. I pasted the hydra body into the scratch buffer:

  (defhydra hydra-zoom (global-map "<f2>")
    "zoom"
    ("g" text-scale-increase "in")
    ("l" text-scale-decrease "out"))

9. I did C-x C-e to evaluate it.

10. I hit F2 to run it.

I got the same results as reported in my OP.

And, again, (as mentioned in my previous post) running

  (defhydra hydra-zoom ()
    "zoom"
    ("g" text-scale-increase "in")
    ("l" text-scale-decrease "out"))

  (global-set-key (kbd "<f2>") 'hydra-zoom/body)

here instead, works fine.

> If I can't reproduce it on my side, I can't do much.

No, that is perplexing.

Is the fact that the overlay (or text properties or whatever it
is) that is supposed to colour some of the letters red in the
hydra prompt actually gets applied at point in the *scratch*
buffer a clue?

Same here.  I can't see how it could operate differently, so I'm
wondering if this is just confusion of expectations.

Oleh, when you say "everything works", do you mean everything listed in
the README?  The thing the OP is saying doesn't work is not mentioned in
the docs, e.g., it says

    - Start zooming in with <f2> g

It never says "hit <f2> and *immediately* get prompted".

Yes, exactly. The two options of binding, either taking up just the
keys the heads need, or the whole prefix are mentioned in the README,
with examples. Patches welcome if it's still not clear.

Hmm, nothing more from OP, the doc does describe correct behaviour, I'm
just gonna close.
