(cl-defmacro debug-warn (&rest args)
|
||||
"Display a debug warning showing the runtime value of ARGS.
|
||||
The warning automatically includes the name of the containing
|
||||
function, and it is only displayed if `warning-minimum-log-level'
|
||||
is `:debug' at expansion time (otherwise the macro expands to nil
|
||||
and is eliminated by the byte-compiler). When debugging, the
|
||||
form also returns nil so, e.g. it may be used in a conditional in
|
||||
place of nil.
|
||||
|
||||
Each of ARGS may be a string, which is displayed as-is, or a
|
||||
symbol, the value of which is displayed prefixed by its name, or
|
||||
a Lisp form, which is displayed prefixed by its first symbol.
|
||||
|
||||
Before the actual ARGS arguments, you can write keyword
|
||||
arguments, i.e. alternating keywords and values. The following
|
||||
keywords are supported:
|
||||
|
||||
:buffer BUFFER Name of buffer to pass to `display-warning'.
|
||||
:level LEVEL Level passed to `display-warning', which see.
|
||||
Default is :debug."
