Inserting special characters?
by Simon Guest 18 Sep '06

18 Sep '06

Hi, How do I insert special characters in a text morph in Squeak? I guess I'm after an equivalent to the Windows character picker, for characters which cannot be typed on the keyboard. It would be nice to see all the symbols available in a font, and pick from that list. cheers, Simon

Problems with do:

I need someone to poke me with a clue stick please! I am trying to step through a file a line at a time. I had the idea that this should work aFileStream nextLine do: [ :line| Transcript show: line; cr.]. Unfortunately (as will be obvious to everyone) what it actually does is print a character at a time. It took me a while to realise that - aFileStream nextLine - is returning a string and the - do: - passing the block to each character. I need a way of passing the block to the string a line at a time. Or perhaps I have got this totally back to front and there is a much easier way of doing this? Cheers AB

Hi andy Well back to front it would be [ :line | Transcript show: line; cr.] value: aFileStream nextLine . which should do what you want.

I personlly do aString = String lf or: [aString = String cr] Is there some more special stuff to test? I have seen Character newPage, what is it? I know that in windows we have cr+lf, grrrr....

How do I test and share code?
by David Pollak 16 Sep '06

16 Sep '06

Folks, I've written a couple of classes that add web-based user management to Pier. The classes let you add new users, remove users, set user's passwords, bless users as superusers, etc. First, I'd like to write some tests for the classes. Ideally, I'd like to similar HTTP requests on Pier (much like I can do when I write Rails tests) such that I'm testing the functionality of the method in the context of living inside Pier/Seaside. Second, how do I publish the code? Is it as simple as following the Montecello example video (I added 1 method to a Pier class and put it in the category *pier-security-manager)? Or is there more magic I have to do? Thanks, David

[to newbies like me] Pretty printing Samlltalk code
by Bakki Kudva 15 Sep '06

This may be old hat to the experts here but I was tickled pink to discover a way to get beautifully pretty printed postscript to my printer...and thought I'd share the info. This is how I did it. I just selected the class category - Seaside-Examples-Store and did a file out, which wrote a 'Seaside-Examples-Store.st' in my image dir. I then opened it with emacs (21) and did a print buffer to postscript form the file menu. That's it! I got a nicely formatted printout with all the comments and a page break after each class so a new class always appears at the top of the page. Thanks to whomever wrote the smalltalk minor mode for emacs :) -bakki

problems with SqueakMap account
by Dave Raymer 15 Sep '06

15 Sep '06

Gentlebeings, I'm not sure if this is the correct place for this question ... but given that I'm a Squeak beginner it seems like the first place to start. I've tried to create a SqueakMap account, and much like building a castle in a swamp -- it fell over. That is, I got a simple "an error has occurred" message. So I tried it again, and guess what, it fell over too. I am now the proud owner of 2 SqueakMap accounts for which I never received the initial login email. I tried the 'mainteiners' [sic] link -- but got an email in spanish that seemed to indicate that the email address for the 'mainteiners' was not good (but my spanish is rotten ...). Any suggestions or guidance would be greatly appreciated. br, Dave
