Hi All,
Here is a moldy oldie from 2005:
http://bugs.squeak.org/view.php?id=1821
The arguments against increasing the size of classes worked
on me. All except two methods which I still use frequently.
They are explode: and mergeDelimited: (I changed the name
of merge: to mergeDelimited: to make it more clear).
"explode the collection into a collection of collections
broken by aDelimiter"
"(#(#(1 2) #(3 4)) mergeDelimited: Character tab ) explode:
Character tab = an OrderedCollection(#(1 2) #(3 4))
'abcdef' explode: 'cd' = an OrderedCollection('ab' 'ef')"
I use these all the time.
Example:
Mail >> replaceTokensIn: aString
^self tokens inject: aString into: [:str
:assoc |
((str explode: assoc key)
mergeDelimited: assoc value value)].
We have templates that users can throw tokens in like {!First
Name} {!email} then we just resolve the tokens and their evaluator block
into an array
tokens: anArray
"Set an array of associations that represent
token - value pairs
being substituted in the email. The keys are
strings to be looked for,
the values are blocks being evaluated to
obtain the string result."
standardTokens := anArray
and process the template.
While these two methods (explode: and mergeDelimited:) never
actually made it into a release I still find them very useful.
Daniela, Your partition looks like my explode.

It's too trivial, surely.
No it is not. Because you have to know about it. Thanks for that one.
"I learned something today[tm]"
But the real things to learn are the Method Finder and the browser. Adding
a lot of names that are known to those that know some scripting language du
jour, but are incomprehensible to me, and no doubt many others, is not doing
anything for anybody, except trying to be pointlessly cool. Trying to
encourage programmers to use the ability of the system to self-introspect
and self-document is giving them general skills they can build upon. So a
project to improve the UI so that programmers are led to tools they can use
for discovery seems worth-while to me, while adding yet more short-hand to
hand-hold the ignorant isn't helping, IMHO.
A modified Finder that had named fields for the formation of the "example"
would go along way. I went a long time without knowing how to work with
this. its a case of you-don't-know-what-you-don't-know

Until now I implemented some missing tests. Right now I'm looking forward to
add new methods that could be useful based on Ruby API
(http://www.ruby-doc.org/core-2.1.0/String.html). These are a few of the
methods that I'm planning to implement:
