I implemented something close to my goal, with $xyz$ syntax for
arguments to be evaluated:
,----
| (de f Args
| (mapcar
| '((Arg)
| (if (atom Arg)
| (let (ChopArgs (chop Arg)
| ArgsTail (tail 2 ChopArgs)
| PunctChars (chop ".,;:?!\"'_-{[]}" )
| ArgLst NIL
| Punct NIL )
| (ifn (and
| (= (car ChopArgs) "$")
| (or
| (= (last ChopArgs) "$")
| (and
| (= (car ArgsTail) "$")
| (member (last ArgsTail) PunctChars)
| (setq Punct (last ArgsTail))
| (setq ChopArgs (head -1 ChopArgs)
| ) ) ) )
| Arg
| (pack
| (val
| (intern
| (pack
| (tail -1 (head -1 ChopArgs)) ) ) )
| Punct ) ) )
| (f Arg) ) ) # use recur/recurse instead?
| Args ) )
`----
using it returns an almost perfect list result:
,----
| (setq
| D1 (date 1999 09 09)
| D2 (date 2000 03 04)
| T1 (time 20 12 05)
| T2 (time 18 03 03)
| S1 (stamp D1 T1)
| S2 (stamp D2 T2) )
|
| (f Is $S1$ before $S2$?
| The answer is
| `(if (and
| (<= $D1$ $D2$)
| (<= $T1$ $T2$) )
| "Yes"
| "No" ) )
|
|
| -> (Is "1999-09-09 20:12:05" before "2000-03-04 18:03:03?" The answer is
"Yes")
`----
only that
"2000-03-04 18:03:03?"
should rather be
"2000-03-04 18:03:03"?
I did not yet make it to write a function g in the spirit of:
,----
| (de g Args
| (glue " " (f Args)) ) # does not work
`----
that then returns a single string:
,----
| "Is \"1999-09-09 20:12:05\" before \"2000-03-04 18:03:03\"? The answer is
\"Yes\""
`----
