MethodName
by Benjamin Van Ryseghem Aug. 22, 2010

Aug. 22, 2010

Hello everybody, I'm working on a new project which consist in merging MethodFinder and MessagesName. The first usable release can be loaded here : Gofer new squeaksource: 'PharoTaskForces'; package: 'MethodName'; load. and it needs NullTextStyler Gofer new squeaksource: 'PharoTaskForces'; package: 'NullTextStyler'; load. To open a Method Name browser, just clic World > Tools > Method Name or MethodName new openInWorld. If you have advice or ideas, I'll thank you a lot ^^ Benjamin

OSProcess and capturing stdout
by Dean Powell Aug. 20, 2010

Aug. 20, 2010

Hi: I'm using Pharo-1.1 OneClick on Ubuntu 10.04. One project I am looking at would require the use of external commands. It appears I can use something like "ExternalUnixOSProcess command: 'do_something --option'" etc. I can perform external commands, but output from these still goes to stdOut. I looked into using CommandShell, but when I try and use this I get grumblings about not findng PluggableTextController and PluggableTextView. Using OSProcess or a subclass, is there a way I can launch an external command but capture the output (say, to a variable)? Does Pharo yet have the equivalent of the c popen() command? Is there a way to load CommandShell without it grumbling about the two packages mentioned above? Any information would be appreciated. Best Regards, Dean Powell Edmonton, Canada

ProfStef or HelpSystem ?
by Francois Stephany Aug. 19, 2010

Aug. 19, 2010

Hi all, What are the differences between the two systems ? From what I see, a ProfStef lesson is a collection of pages with buttons to navigate between them. Help System seems to be same except that it can have a hierarchy of pages and is more 'textual' than a ProfStef lesson (the absence of syntax highlighting confirms that?) Now I don't see why there are two different browsers/systems ? Sorry if I'm missing something evident :/ Francois

String insertion
by Simon Denier Aug. 19, 2010

Aug. 19, 2010

What's the best (most elegant/efficient...) way to insert a string into another string at a given index? Say I have the string 'Toto-Tata-Titi' and I want to build the string 'Toto-Tests-Tata-Titi' I could think of the following: | string sepIndex stream | string := 'Toto-Tata-Titi'. sepIndex := string indexOf: $-. stream :=String new writeStream. stream nextPutAll: (string copyFrom: 1 to: sepIndex). stream nextPutAll: 'Tests'. stream nextPutAll: (string copyFrom: sepIndex to: string size). ^ stream contents Any suggestion? -- Simon

Is there a menu option to browser a class directly?
by TimM Aug. 18, 2010

Aug. 18, 2010

Hi guys - sometimes I want to lookup a class (ideally its hierarchy*) directly. Is there a convenient way to do this quickly? Here's my scenario: - I am using a System browser, and looking at my Package? of classes (not sure what its called - but my grouping of classes). - It occurs to me in the middle of entering a new method that I may need to use class XXXX (e.g. CTPusher) - but as I'm not familiar without I want to browse its methods - So I want to quickly browse that class and explore its methods - but I haven't figure out how to do that quickly and easily? It seems I have the following options: 1) Type the name of the class in the mercury panel - if I don't type it fully then it does open a new window for me (not bad - but I sometimes type the full name). If I type the full name, or autocomplate it advances me in my current browser - forcing me to save my changes (which often aren't good enough to save yet), and I also lose my place in my method (and there is no back/history to get back there quickly) 2) Open a new system browser, then type the name of the class in the mercury panel - and it then takes me there (this isn't a bad option - but it feels a bit less immediate somehow. 3) Type something in my current source - and then use Cmd-B (not bad - but when I come back I may have to backspace over the name if I found something else 4) Use some other tool (was it Algernon that did something like I want?) I guess I'm wondering why in the Tools menu of the OS - there is a Method Finder option, but not a Class Finder option? Do you guys have any tricks for me. Tim *the reason I like to browse the hierarchy, is often there are inherited methods that i can't easily see in Pharo. I wish there was a "show inherited methods" option that shows all methods with icon to show you inherited them (and you could double click it to go to the superclass that implements it). I think for you experts you don't notice this so much, but when you are trying to find your way - it really feels like a lot of work to find things.

TIFF support.
by George Herolyants Aug. 17, 2010

Aug. 17, 2010

Hi everybody. Though squeak.org says there is a TIFF files support in Squeak I can't find any signs of it. So, could someone point me to the actual TIFF files reading/writing library for Squeak/Pharo? Thanks.
