Hello,
* TFPList
Is there another way to traverse a list than
for i :=0 to (list.count - 1) do ...
What about list.high?
Also, is it possible to set a list's base index to 1 (so that last_index=count)?
There is a super handy forEachCall method (calling a proc for each item), but I
cannot find a matching map method (calling a func and storing results).
* string <-> number
I could not find _functions_ to operate such conversions, only _procedures_ str
and val. So that I always end up with superfluous statements and temps
variables:
str(n,text);
writeln(text);
vs
writeln(NumbetToString(n));
Ok, I can write these funcs (I did ;-). But how comes there are no builtin
functions for that?
* string section
Is there another way to slice a string than using copy. In particuliar, the
count argument is not always practical to indicate the end_of_section position.
(count = last-first+1)
* array value notation
I can set a static array's value on declaration line, but could not find a way
to do it later (even less to change it). And I cannot find a way to set the
value of a dynamic array --when it's not fed from a loop. End up with series of
arr[i]:=v statements (code from the http://en.wikipedia.org/wiki/Middle_ages
;-). Same for lists, indeed.
var
arr : array [1..2] of Integer;
...
i:=1 ; j:=2;
arr := (i,j);
==> Syntax error, ")" expected, but "," found
Finally: is there a wiki version of the official docs, to collectively enhance
them (with notes, examples, explanations...). (I'm dreaming, but after all fpc
is free software, and it's the #1 reason why I chose it.) (*)

(*) This gives me an idea: a converse doc system that takes properly formatted
doc and inserts proper parts of it as comment into the code at their proper
place -- not the contrary ;-)
