Re: [PhillyOnRails] A simple comparison for a task in Objective-C vs. Ruby on Mac...
|
To Rail-ites in the City of Brotherly Love,
Hello from Kansas City.
CAVEAT EMPTOR. For those who who dislike receiving
MS-WORD attachments, please delete this e-mail before

Justin R.,
Just a follow-up example attached comparing a simple
Objective-C
program to the same task using Ruby on the Mac. It
sheds some light on naming conventions often used in
Cocoa applications.
You "ain't just whistin' dixie" when you talk about
some awkward
naming conventions in Cocoa, which uses the
Objective-C "NS" calls
in the Foundation Toolkit.
This reminded me of the old days when you wrote X code
and had every line of code beginning with something
like "Xt" or "Xlib" with
the GUI Motif calls staring with "Xm". When you call
"every animal
in the barn XtHorse or XmCow", I don't think it
particularly improves
readability.
Of course, it was Disraeli who said, "it's easier to
be critical than to be correct", so I thought I'd at
least write a side-by-side (attached as a WORD
file):-)
Hope this helps. I do still enjoy using Objective-C,
and will never give up C entirely. However, the
"line-by-liner" shows the appeal of using Ruby
instead. Less LOC to get calculation entities such as
arrays rendered as objects means far fewer headaches
in the maintenance phase, where 70% of project budgets
are spent.
