[Pharo-project] Smalltalk string API
by Nicolas Cellier Feb. 16, 2011

Feb. 16, 2011

I started referencing Smalltalk idioms at http://en.wikipedia.org/wiki/Comparison_of_programming_languages_(string_fu… I could have focused on ANSI but have chosen Squeak/Pharo. Feel free to correct me and to complete me. This is a very enlighting exercize, especially for pointing when API turns to be not that bright. During my perigrination, I notably noticed this: #compare: returns 1, 2, or 3 : this is both very object oriented, very intuitive and very standard and the rest of the world is stupid, unless... #findLastOccurrenceOfString:startingAt: in its current form is stupid to my taste, because 1) implementation is inefficient 2) the startingAt: only skip the beginning of the string which seems odd for a rfind operation I would rather expect this kind of usage: last := aString findLastOccurrenceOfString: 'to' startingAt: aString size. lastButOne := aString findLastOccurrenceOfString: 'to' startingAt: last - 1. The CamelCase is sometimes abusive like #includesSubString: There is no format. I know, purists will tell me that encoding a format in a cryptic string is not in the Smalltalk spirit, but please then tell me how to specify a formatting efficiently and also remove cryptic regex encoding (a pity, it's not in trunk). I let a few holes (split/join etc...) Cheers

Status: New Owner: ---- New issue 3719 by georgi...(a)gmail.com: No OmniBrowser! http://code.google.com/p/pharo/issues/detail?id=3719 I try to follow the book Pharo by Example. Pharo on my Mac doesn't have OmniBrowser as its default class browser. On page 318 of the book it reads that in order to change the default class browser, I must change it to O2PackageBrowserAdaptor, but I cannot find it anywhereâ¦ Is there a way to fix this? Thanks, Anthony
