Nice! :) <http://forum.world.st/file/n4813138/font-importer.png> Two questions: 1. Who does the rendering? Looks kind of irregular... See attachment. 2. Can we move it to the "Tools" package?

New, faster RISC OS Squeak
by Chris Cunnington 01 Oct '16

I get a File 'System:Modules.StreamMan' not found error. I take it from here [1] [2] that StreamMan is short for StreamManager. And that it should be in the sharedsoundbuffer.!System folder. I shift+double clicked and followed !Shared.350.Modules to see StreamMan in this directory. The file appears present but still there is an error.

Re: [squeak-dev] International text input on X11

Hi Tim, As the VM changes for this matter is in shape (if I'm not mistaken, the plugins.ext has to have ImmX11Plugin), the following image side changes will greatly help the usability for kids in Japan and elsewhere. Can you add those at some point?

Time millisecondClockValue (was: The Trunk: Morphic-mt.1080.mcz)

Hacking during the switch from DST to normal time forced the user to wait one hour. Opening images from different time zones did also show this bug. What?! Time millisecondClockValue is supposed to be continuous. I’ll have to admit I didn’t follow the previous discussion too closely, but syncing millisecondClockValue to the wall clock seems like a very bad idea. - Bert -

UTCDateAndTime updated for Squeak 4.6/5.0
by David T. Lewis 08 Jul '16

08 Jul '16

UTCDateAndTime is a UTC based implementation of class DateAndTime with one instance variable representing the magnitude of the point in time, and another representing local time zone offset. I recommend loading with the SAR from http://wiki.squeak.org/squeak/6197, as maintaining this in Montecello is problematic. After the 4.6/5.0 release, I would like to suggest moving Chronology out of the Kernel package into its own package, so that changes in Chronology can be maintained in Montecello without conflicting with the rest of Kernel. Spur notes: The Spur image provides a huge performance when loading this set of changes. There are two steps in the loading process in which all DateAndTime instances need to be #becomed into new instances. This is painfully slow in the traditional image (with or without Cog), and it is amazing fast in Spur. That said, there is a bug in the Spur VM (easily resolved I think) that produces incorrect time values. I'll post note about that on vm-dev. I would not recommend using UTCDateAndTime in Spur yet, other than just to see how amazingly fast it is compared to loading the same thing in a non-Spur image. Dave

Running headless on a Mac
by Frank Shearar 03 Jul '16

03 Jul '16

OK, so I've run out of patience in my flailing around. All I want is to run a headless image on a Mac (so I can unbreak the SqueakTrunk-OSX job, which _used_ to work). How? Do I say "-headless"? ("could not find module vm-display-X11") "-vm-display-null -headless"? ("squeak: could not find any sound driver") "-vm-sound-null -vm-display-null -headless"? ("could not find module vm-sound-null") I don't mind whether I use Cog or Interpreter, as long as I can just get an image running tests. Thanks! frank

Impossible to grab the scroll bar in the Transcript if...
by Eliot Miranda 08 Jun '16

08 Jun '16

Hi All, if the Transcript is open and reasonably full of text and scrolled os that the scroll bar is at the bottom right corner of the window one cannot (at least I cannot) grab the scroll bar to scroll the Transcript contents because the cursor is cooped into window resizing (the window resize cursor is shown). :-( _,,,^..^,,,_ best, Eliot

#caseOf:otherwise: -> Parser is way too cautious
by marcel.taeumel 05 Jun '16

05 Jun '16

Hi, there! I cannot write this without the parser complaining: number caseOf: { 0 -> 1. 1 -> 1. } otherwise: { ... }. Because what I should write is this: number caseOf: { [0] -> [1]. [1] -> [1]. } otherwise: { ... }. I think that this is not for the parser to decide. Numbers do understand #value. Any object does. So this is fine. Am I missing something? It reminds me of this mistake our students typically make at least once: (someBooleanExpression) and: (someOtherBooleanExpression) versus (someBooleanExpression) and: [someOtherBooleanExpression] versus [someBooleanExpression] and: (someOtherBooleanExpression) versus [someBooleanExpression] and: [someOtherBooleanExpression] Sure, we can offer tool support to help in such situations. But the parser is just too naggy. :-) Best, Marcel -- View this message in context: http://forum.world.st/caseOf-otherwise-Parser-is-way-too-cautious-tp4897986… Sent from the Squeak - Dev mailing list archive at Nabble.com.

Files-ul.154 seems dangerous, is it needed?
by David T. Lewis 03 Jun '16

03 Jun '16

We did this change recently: Name: Files-ul.154 Time: 15 May 2016, 11:17:08.015805 pm - use #adoptInstance: to convert between binary and ascii mode instead of creating new collections This assumes that we can convert a ByteString to a ByteArray using Behavior>>adoptInstance. If the conversion does not work, as it the case with a V3 image and Cog or interpreter VM, then we end up with a corrupt image after trying to save the image as new version (and maybe other cases as well). It does not seem that #ascii and #binary are called frequently, even when doing Monticello updates, so I suspect that the optimization is not very important. Do we need the #ascii and #binary optimizations in Files-ul.154? Dave

Just curious, why are you adding spaces everywhere? :) Best regards -toibas
