Hi Alex,
I am now working on the "Arrays" section at "Find First Element that passes
a Test".
Your example:
(with
(find
'((This) (== 'engineer (: category)))
Employees )
(prinl "Highest paid engineer is: " (: name)) )
This won't work of course, so I created a few things:
: (setq emp1 "Abel" emp2 "Jones" emp3 "Millner" emp4 "Noles" emp5
"Zaphod")
-> "Zaphod"
: (put emp1 'category 'engineer)
-> engineer
: (put emp2 'category 'cook)
-> cook
: (put emp3 'category 'teacher)
-> teacher
: (put emp4 'category 'engineer)
-> engineer
: (put emp5 'category 'vicar)
-> vicar
: (setq Employees '(emp1 emp2 emp3 emp4 emp5))
-> (emp1 emp2 emp3 emp4 emp5)
I guessed that this list Employees would be OK to feed 'find';
however, from the ref docs of 'with' I do not grasp how I should get this
to work.
Also, the function used by 'find' has a formal parameter named This. Is
this the PicoLisp special variable, or just a name for a formal parameter?
Please give a complete example!
What I experience now is exactly why I think that there should be more and
better approachable docs.
I think the reference should either be expanded by more comprehensive
examples + explanations, or otherwise I'll try and do that later in the
Wiki where I started the new section (with now only the 'de' example).
I feel you, because it is all "in your head", but B2B a.k.a. brain-2-brain
is not yet possible, regrettably :)
Seeing all this stuff i am convinced that PicoLisp also could have been
named YottaLisp, because of the sheer amount of possibilities hidden below
the surface :)
Best,
Arie
