Available PROPS:

`:on-enter SEXP'
|
|
Evaluate SEXP when the transient state is switched on.
|
|
`:on-exit SEXP'
|
|
Evaluate SEXP when leaving the transient state.
|
|
`:doc STRING or SEXP'
|
|
A docstring supported by `defhydra'.
|
|
`:additional-docs cons cells (VARIABLE . STRING)'
|
|
Additional docstrings to format and store in the corresponding VARIABLE.
|
|
This can be used to dynamically change the docstring.
|
|
`:title STRING'
|
|
Provide a title in the header of the transient state
|
|
`:columns INTEGER'
|
|
Automatically generate :doc with this many number of columns.
|
|
`:hint BOOLEAN'
|
|
Whether to display hints. Default is nil.
|
|
`:hint-is-doc BOOLEAN'
|
|
Whether the hints act as a documentation, the only effect of this value is
|
|
to change where the hints are displayed. If non-nil the hints are displayed
|
|
on the same line as the `:title', otherwise they are displayed below it.
|
|
Default is nil.
|
|
`:dynamic-hint SEXP'
|
|
An sexp evaluating to a string for dynamic hinting.
|
|
When provided `:hint' has no effect. Default is nil.
|
|
`:foreign-keys SYMBOL'
|
|
What to do when keys not bound in the transient state are entered. This
|
|
can be nil (default), which means to exit the transient state, warn,
|
|
which means to not exit but warn the user that the key is not part
|
|
of the transient state, or run, which means to try to run the key binding
|
|
without exiting.
|
|
`:bindings EXPRESSIONS'
|
|
One or several EXPRESSIONS with the form
|
|
(STRING1 SYMBOL1 DOCSTRING
|
|
:exit SYMBOL)
|
|
where:
|
|
- STRING1 is a key to be bound to the function or key map SYMBOL1.
|
|
- DOCSTRING is a STRING or an SEXP that evaluates to a string
|
|
- :exit SYMBOL or SEXP, if non nil then pressing this key will
|
|
leave the transient state (default is nil).
|
|
Important note: due to inner working of transient-maps in Emacs
|
|
the `:exit' keyword is evaluate *before* the actual execution
|
|
of the bound command.
|
|
All properties supported by `spacemacs//create-key-binding-form' can be
|
|
used."
