Cannot use SPC as a head ??

[nobrowser]

I am a complete newbie with hydra, so I must be doing something wrong. Here is my definition:

(defhydra itz-move-hydra ()
  "move and select"
  ("SPC" set-mark-command)
  ("." forward-sentence)
  ("," backward-sentence)
  ("]" forward-sexp)
  ("[" backward-sexp)
  ("<return>" forward-paragraph)
  (";" backward-paragraph)
  ("b" backward-word)
  ("l" forward-char)
  ("h" backward-char)
  ("j" next-line)
  ("k" previous-line)
  ("n" forward-list)
  ("p" backward-list)
  ("u" backward-up-list)
  ("w" forward-word)
  ("x" exchange-point-and-mark)
  ("q" nil))

When I bind this to a key, everything works - except the SPC. Hitting space just inserts a space in the buffer and slays the hydra, as if the binding didn't exist.

I see that SPC is used in one of the examples, so it is at least expected to work ?!

This works for me with <SPC>

This works for me with <SPC>

What version of emacs, @DieracDelta ?

I think I tried <SPC> too ... and anyway, when I bind SPC to any other command, it works OK, so I suspect this is something special about set-mark-command.

I'm on emacs 26.3. Turns out both SPC and <SPC> work for me. Not too sure where your problem lies. Maybe something else in your config is messing things up? I'm also drawing the package from ELPA on nixos.

@nobrowser Your definition works as expected for me. It's likely a config issue.

You can test your hydra without config by doing:

git clone https://github.com/abo-abo/hydra/
cd hydra
make run

If it works, you can comment out parts of your config until it works as well.
