I've CC'ed the gnu-apl list with my answer to Christian's question, since I
think this is an interesting discussion. For the newcomers, this is about
the solution to this Codejam question:
https://code.google.com/codejam/contest/6254486/dashboard#s=p1
It's quite simple actually. The idea is simply
No, I really mean ⎕FIO['fopen'] as native function.

That's a *lot* more than what we need. I think.
But a good ending
Sure, that shouldn't be a problem at all.

Jürgen,
While we are at it,
Can ⎕FIO[something_integer] can be made to understand also things like:
⎕FIO['fopen']
⎕FIO['fclose']
⎕FIO['popen']
⎕FIO['read']
and so on ? Would simplify coding time a LOT and help readability !
my 2 cents,
Xtian.

Oh yes, would be nice. (pcre would be as nice as regex, may be more)
make it a ⎕regex or ⎕pcre so, no need to load a specific .so file or )lib to
use it ;-)
Ideal would be to be able to not only scan but be able to compile a pcre, find
patterns, search & replace ...
I am dreaming, but still a
Would anyone be interested if I actually implemented support regex by
calling into the C library?
I'm envisioning something like this:
* "^([a-z]+):([0-9]+)$" regex∆scan "foo:123"*
┏→━━┓
┃"foo" "123"┃
┗∊━━┛

At some point I really wanted to implement the simplest editor, namely ed (it
would be much better than any APL system has offered), in APL, but I never
finished the regex part. Perhaps it would be a nice exercise for someone who’s
interested in learning APL to actually implement some of the mo
Well, that was not exactly what I was seeking (condense), but, that "toronto
toolkit"
looks like a very interesting piece of code/functions ...
deciphering/decoding/understanding each one should enlighten me on apl
operators/data and usage.
I will look at it.
thanks,

Hi,
A more general purpose search&replace (some bug fixed), take (2), was "snr".

An alternative (from hans-peter sorge from this list, april 13, 2016).
Careful though, this does have some edge conditions which will bite:
⍝replace with ( is 2 elements) in string

⍝.n hans-peter sorge
⍝.t 2016.4.13.0.0.0

For this, try the "toronto toolkit" in our bits&pieces.
There is a function "condense"
' ' condense ' a b c d '
a b c d
Which is what you want (I think). Uses ∆db (delete blanks). Preferable
to get from the toolkit -- functions reproduced below.
∇y←d condense v;b

Hi Xtian,
how about this:

Hi
coming back to an earlier discussion, I have added ⎕EB
("Execute Both") to GNU APL.
A ⎕EB B
is similiar to A
⎕EA B in that it first executes B. However,
unlike
⎕EA which
executes A only when B fails, ⎕EB always
executes A regardless
I have been thinking of writing a native integration of regex which can be
integrated in GNU APL.
I haven't needed to yet though.

Elias

Looks like a job for regexp…
Too bad APL doesn’t have one.
