You can use func-arity added in 26.1. C-h f func-arity:
func-arity is a built-in function in `C source code'.
Return minimum and maximum number of args allowed for FUNCTION.
FUNCTION must be a function of some kind.
The returned value is a cons
cell (MIN . MAX).
MIN is the minimum number of args.
MAX is the
I figured it out. You have to select the port map by entering into it, and doing:
After that, you can place the component, or create the testbench with
M-x vhdl-port-paste-testbench in a new testbench file.
Not exactly. Function buffer-substring requires two arguments. Function - will accept a single argument, but in that case it just returns the negative of that numeric argument. What you want to do is, in effect, apply such functions to a list of arguments. You can use higher-order function apply to do that.
What you can do, if you want, is have a macro or ...
You might want to have the documentation display immediately when you type C-h f on a command (that is, without having to press <RET>), while keeping the original behaviour of being able to type the function name when you're anywhere else.
That is not so trivial to do, because function-at-point is very greedy. Telling it to display its first ...
The typical way this is done is by assigning the custom commands to keyboard shortcuts of a given major-mode; e.g.,
add to your Emacs init file
;; Add commands to python mode
and then either
