app in app
by Chuck Smith 31 Jan '18

31 Jan '18

Dear Squeakers, I have always had a hard time learning anything until I had a project to do it around. Well that time has come. I need to write an app. that will let me run one application inside another. I would like to have a cad type app. running in a window and then be able to over lay that cad app. with another app. that lets me put hot spots on the cad app. These hot spots will have the ability to show a colored outline around their perimeter. That outline we would like to be able to turn on and off or make blink. The purpose of the hot spot is to train people how to use the cad app. by showing them where to pick menu items and enter data etc. So the whole things runs like this, we start the cad app. and the tutor app. The tutor app. step by step shows the student where and what bottoms to pic and where and what data to enter. As they enter etc. the app. actually functions and they are able to create in the cad app. Kind of a training wheel effect. Can any one tell whether or not I could do this in Squeak and kind of help me do it. I do have a nephew who is a good programmer but has never used Squeak of small Talk and I would like to get him help me do this app. start using Squeak. Can any one point in the right direction? I would like to do the same thing for learning Squeak. Once we learn how to do it for the cad app. I will do it for the Squeak community and make it free. Sincerely, Chuck Smith

Squeak newbie- VisualWorks to squeak
by OldSmallTalker 29 Jan '18

29 Jan '18

After 20 years of VisualWorks development, I got laid off. I'm switching to Squeak. Are there any GUI development tools similar to the VW tools I'm familiar with? -- Sent from: http://forum.world.st/Squeak-Dev-f45488.html

String >> utf8Encoded, ByteArray >> utf8Decoded
by Tony Garnock-Jones 29 Jan '18

29 Jan '18

Pharo has these two convenience methods: String >> utf8Encoded ByteArray >> utf8Decoded It looks like, roughly, - Pharo's "aString utf8Encoded" is equivalent to Squeak's "aString squeakToUtf8 asByteArray", and - Pharo's "aByteArray utf8Decoded" is equivalent to Squeak's "aByteArray asString utf8ToSqueak". Should we add definitions like the following to Squeak? String >> utf8Encoded ^ self squeakToUtf8 asByteArray ByteArray >> utf8Decoded ^ self asString utf8ToSqueak ? It takes me an age to find the proper Squeakly incantation every time I work with network protocols in Squeak. I think these convenience methods would help. Tony

Re: [squeak-dev] Unicode display support in text morphs?
by Lawson English 28 Jan '18

28 Jan '18

Thanks. The solution you suggested is almost incomprehensible to me. I'm using a Mac and it sounds like perhaps the plugin isn't available on the first place? This is somewhat ironic since Apple's unicode support is better than anyone else's (I'm told that Unicode was originally a joint project with Apple and XEROX back in the day, anyway). I've got my own workaround currently which is to do screen shots of BBEDIT or TextEdit ,one large-point char at a time, and import the bitmaps into squeak. This is repugnantly awful, but oh well.

An idea for the debugger...
by Eliot Miranda 28 Jan '18

28 Jan '18

Hi All, I'm lazy and also I don't write the most elegant UI code but I had an idea I want realized so I thought I'd see if I could interest anyone in implementing it. Dora is doing amazing work with the Moldable Debugger but this is a poor man's alternative that can get us a lot of benefit. In the JIT I find myself wanting to run a number of doit while debugging to print out information, change virtual breakpoint locations (where a variable is tested and if the JIT is at the right point halt is sent) etc. Typically one has to type these into the receiver inspector in the bottom left of the debugger. Having some strings in the paste buffer helps in not typing them but one has to load the paste buffer at least once before a debugging session and its tedious. I modified the inspectors in VMMaker already so that one can choose the default base used to display numbers because hexadecimal is much more useful in looking at machine code, the GC, object headers, etc. So how about this... A class may implement something like receiverMenuForDebugging, either on the instance or the class side. Whenever the receiver inspector is asked to open up the yellow/middle button menu on its list it checks for the presence of receiverMenuForDebugging and adds this as a submenu being the first item in the menu. So one can write all the application specific snippets one wants and invoke them quickly and conveniently from this menu. Anyone interested in implementing this? It would make my day, hell it would make my month, and make my year so much nicer :-). _,,,^..^,,,_ best, Eliot

Running Squeak on Chrome OS
by Ralph Boland 28 Jan '18

28 Jan '18

I am writing in Squeak some software for teaching (mostly math) to kids (ages 4-10). These kids and their schools often have chrome OS based computers. So it would be great if my software can run on these machines. So I would like to know the status of Squeak (and perhaps Pharo) in terms of running on chrome OS. Also, I would be able to take advantage of the touch screen these devices have. Where is Squeak in terms of using touch screens? Ralph Boland

Displaying Strings and Texts in workspaces.
by Eliot Miranda 27 Jan '18

27 Jan '18

Hi All, I notice with some dismay that String>>openInWorkspaceWithTitle: was deleted some time ago. Note that there is still a sender in the GetText package. Writing either (StringHolder new contents: myString) openLabel: 'W. T. F?!' or (Workspace new contents: myString) openLabel: 'W. T. F?!' is a pain in the ass. So should we have a class side method on StringHolder, openOn:label: for example, or put back the most convenient openInWorkspaceWithTitle? _,,,^..^,,,_ best, Eliot
