I also wondered, what if another kind of behavior comes along one day? Then ...classOrTrait... might be the wrong choice (or name, depending on the implementation) again. After more thought, I would rather like to scrap this patch and change MCMockPackageInfo>>classes in the other patch to use #hasBindingOf:. It looks up its own "well known" symbols anyway, that's why I think it can even forgo the behavior type check. And if the other patch is not accepted, this one will not be required anyway. To fullfill my commit message, there should rather be a hasBehavior:/behaviorNamed:/behaviors triple, shouldn't it? 2017-02-13 15:57 GMT+01:00 Bert Freudenberg <bert(a)freudenbergs.de>: > On Mon, Feb 13, 2017 at 1:08 PM, Jakob Reschke > <jakob.reschke(a)student.hpi.de> wrote: >> >> classNamed: OTOH does not check the type and will also return a Trait. > > > That's because it predates traits and has not been updated. Actually, it seems to have been updated in SystemDictionary to be "^ self classOrTraitNamed: className", and then was copied over to Environment later.

Squeak/Seaside/Raspberry Pi GPIO program
by Louis LaBrunda 13 Feb '17

13 Feb '17

Hi All, I have been working on a small Squeak program that uses Seaside to present a couple web pages that allows the user to close a relay attached to the Raspberry Pi. The first version of the software is working. I have a little relay/hardware work to do and I'm waiting on parts. Tim Rowledge's new Hardware-Peripherals package loads just fine. Thanks Tim. In addition to Hardware-Peripherals, my code needs the Cryptography stuff, Ma-Serializer and Seaside. Can I add these as "required packages" to my package and have everything loaded at once? I think I had to install Metacello before I could install Seaside. I'm new to Squeak/Metacello and packages so, thanks for any help in advance. Lou -- Louis LaBrunda Keystone Software Corp.

Agreed. I based this on hasClassNamed: which uses the isKindOf: check as well. classNamed: OTOH does not check the type and will also return a Trait. 2017-02-13 12:01 GMT+01:00 Bert Freudenberg <bert(a)freudenbergs.de>: > On Sun, Feb 12, 2017 at 4:56 PM, <commits(a)source.squeak.org> wrote: >> >> A new version of Environments was added to project The Inbox: >> http://source.squeak.org/inbox/Environments-jr.70.mcz >> >> ==================== Summary ==================== >> >> Name: Environments-jr.70 >> Author: jr >> Time: 12 February 2017, 3:42:16.327498 pm >> UUID: cbbca4a2-6a97-2b40-92b8-631bbfa519d0 >> Ancestors: Environments-jr.69 >> >> add hasClassOrTraitNamed: >> >> useful for lists of behaviors >> >> =============== Diff against Environments-jr.69 =============== >> >> Item was added: >> + ----- Method: Environment>>hasClassOrTraitNamed: (in category 'classes >> and traits') ----- >> + hasClassOrTraitNamed: aString >> + Symbol hasInterned: aString ifTrue: >> + [:symbol | | value | >> + ^ ((value := declarations at: symbol ifAbsent: [nil]) >> + isKindOf: Class) or: [value isKindOf: Trait]]. >> + ^ false.! > > > Please do not introduce #isKindOf tests.

One might add that there is Ctrl+1, 2, 3 ... to open the main docking bar menus. But for whatever reason, the "open context menu" key next to the right ctrl key is ignored by Squeak. Is there a reason other than Esc doing the same thing or "never cared"? I still do prefer immediate keyboard shortcuts, as I pointed out. Clicking ToolBar buttons in VAST is not as fast as cmd-m in Squeak is. Would be good if shortcuts were overridable by the focused widget, however. 2017-02-13 3:05 GMT+01:00 tim Rowledge <tim(a)rowledge.org>: > >> On 12-02-2017, at 3:58 PM, Chris Muller <asqueaker(a)gmail.com> wrote: >> >> The only alternative to a global hot-key is the mouse. >> >> For example, to open the Monticello browser: >> >> 1) grab the mouse, start moving it upward and to the left >> 2) locate the ascending hand on the screen, aim for the "Tools" menu >> 3) click Tools >> 4) click Monticello > > Or menu button over the desktop, -> open -> Monticello Browser > a) this, like almost all our menus could be improved if all the multiple menu setups were properly changed to hierarchical menus > b) I argued with Jef Raskin for a couple of years about why I thought Smalltalk’s 'menu where I clicked’ approach was better than the original Mac notion of the global menu bar - his point was largely that he used Fitt’s Law to make the target very large and easy to hit.

Vote?
by Ron Teitelbaum 12 Feb '17

12 Feb '17

Hi All, Ok, so you are probably wondering why is Ron bugging us about voting? Besides the fact that time is running out, our voter count is 13% lower than last year. It would be nice if those of you that are on the voter list could fix that! Also, it probably means that I'm not doing enough to encourage people to join the voter's list! Please take a minute and show your commitment to the board by getting on the voter's list for next year! Send me an email to get on the list. Thanks! All the best, Ron Teitelbaum

I hope the alternative is "local" hotkeys, such as cmd-n and cmd-m being "local" to SmalltalkEditors. Luckily, SmalltalkEditors are ubiquitous in our tools... I miss senders/implementors hotkeys big time in the old VA Smalltalk version available to me. 2017-02-12 21:16 GMT+01:00 Tobias Pape <Das.Linux(a)gmx.de>: > > On 12.02.2017, at 21:14, Stéphane Rollandin <lecteur(a)zogotounga.net> wrote: > >>>> >>>> My point is that global hot keys are not only scarce, every new one we >>>> introduce becomes a possible overload with applications that may wish >>>> to use those keys for something else.
