A small quiz: longest selector

Hi,

I've got a small quiz question for fun: What is the length of the
longest method selector in Pharo?

Before you will write an oneliner to get the exact result, try to make a tip ;-)

Cheers,

I will have bet on a Morphic method, but the result is surprising :)

#subclass:instanceVariableNames:classVariableNames:poolDictionaries:category: ? probably not, but that's the first thing that came to mind...

Re: A small quiz: longest selector

Hmm, I did that in #281 …

How can there be a longer selector if that was the longest symbol ?

This is fun ;-)

Re: A small quiz: longest selector

hmm, well, as I see I haven't used clean image, there was Tanker in
it. One selector there has 189 characters :-)

Good oneliner.

But why `Symbol allSymbols asSortedCollection last`

Doesn't return the same?

Pavel Krivanek-3

Re: A small quiz: longest selector

it sorts by alphabetical order, not by symbol size

Excellent, I didn't look into its implementation.

Thank you Pavel.

Woot! I've needed this several times and hand-rolled something because I didn't know it existed... and to think this thread started as a joke...

Re: A small quiz: longest selector

This means that a browser which is just like a regular natural
language dictionary could be useful. A list of buttons (or a list)
with A...Z and then just the list of selectors and their class and
comment.

Not actually new thing. I think Ernest Micklei from the Netherlands
had a web site displaying Smalltalk methods this way it seems no
longer accessible.

Such a list in the browser would be much handier.

--Hannes

Another note:

The discussion about Symbols reminds me that we actually have 'Atoms'
in Smalltalk. More on this see
http://live.exept.de/doc/online/english/programming/stForLispers.html

"Like Lisp, Smalltalk provides atomic character strings, called
"symbols". In Smalltalk, these behave much like strings, with the
exception of being read-only (i.e. their character elements cannot be
changed) and being unique (i.e. they can be compared using the
identity compare operator #'==', as opposed to strings, which should
be compared using the equality operator #'=').
The Smalltalk message "asSymbol" corresponds to the Scheme
"string->symbol" function. "

Here is the blog entry

However the actual product http://soek.goodies.st/ is no longer available....
