I asked it for a NeoCSV example, because the documentation is out
of date
with the Pharo 10. I asked it to do some simple saving of data to
a file.
It gave me code that didn't work in Pharo 10, I told it about the
DNUs on
the csvwriter and that I was using Pharo 10. It then apologized
and said
the messages were later introduced in Pharo 50 (!). I then
questioned its
understanding and it apologized and said it had been confused and
that it
was giving me code for Pharo 5.0. It seems to have trouble with
versions
and quick changing APIs. So, we are teaching ChatGPT about
smalltalk, too,
when we try to use it.

It works much better when you can spot the mistakes, you can
tell them to
add some considerations to the code or even point the LLM to
correct a
message selector to something else. Sometimes you ask it to
reprogram
something and it won't do it, as if it doesn't understand what
you're
asking.
It is not an expert yet, but it is a great assistant. The only
thing is
that is sure is that it will get better.

"#isOdd is not Smalltalk" - doh, I typed it in on my phone and
so it just
goes to show that it highlights the flaw in chatGPT that others
have called
out in other languages. I had meant to find some trickier code
samples to
see how well it does...
Still, it is very interesting how it reasons on this stuff -
and I wonder
if there is way to tell it about these mistakes? For example is
it reading
this email (or will it in the future) and understand that it is
#odd and
not #isOdd.

#isOdd is not Smalltalk, neither Pharo 10 nor VAST 12
understands this
message ;-)
If I evaluate your snippet -replacing #isOdd for #odd, I get an
empty
Collection. The divisible by 4 things is somewhat interesting,
because (1
to: 100 by: 4) is amn interval 1,5,9 etc.... ;-)
So chatGPT is probably a newbie in Smalltalk. Interesting is
how logical
the explanation sounds, you're tempted to believe it...

it's interesting to see how the answer changes with only a
small change
on the question:
(1 to: 100 by: 4) reject: [:i | i isOdd]
gives:
The code creates a collection of numbers from 1 to 100,
incrementing by 4
at each step using the to:by: message. It then applies the
reject: message
to this collection, which returns a new collection containing
all elements
for which the given block evaluates to false.
In this case, the block is [i | i isOdd], which checks whether
a given
number i is odd using the isOdd method. So the result of the
entire
expression is a collection of all even numbers between 1 and
100 that are
divisible by 4.

Of course everyone is talking about ChatGPT, and I saw a post to
ExplainCode and didn’t expect it to understand Smalltalk, so
was impressed
that it does! Presumably the Tonel Smalltalk code on GitHub has
helped
along with numerous articles?
Try it out: https://whatdoesthiscodedo.com/
I gave this simple example: (1 to: 100 by: 3) reject: [:i | i
isOdd]
And got this (neat eh):
The code above is written in the programming language Smalltalk.
It creates a collection of numbers from 1 to 100, incrementing
by 3 at
each step. This is done using the "to:by:" construct where the
starting
value is 1, the ending value is 100, and the increment is 3.
The resulting collection is then filtered using the "reject:"
method,
which takes a block of code as an argument. In this case, the
block checks
whether each element (denoted by the variable i) is odd by
using the
"isOdd" method. If an element is odd, it will be rejected from
the
collection.
So, the final result is a collection of all even numbers from 1
to 100,
incrementing by 3 at each step.
