error "please insert disk" (windows vm)
by Nicolai Hess Jan. 15, 2017

Jan. 15, 2017

we have the following bug report 16928 <https://pharo.fogbugz.com/f/cases/16928/no-disk-in-the-drive-reply-to-World…> "no disk in the drive" reply to World | Save As (and other places) "On a clean Pharo4.0 #40618 image, on Windows 7 World Menu | Save As brings up a modal alert window, "There is no disk in the drive. Please insert a disk into drive <etc>" On my system, it does this 4 times. I'm assuming that each instance refers to one of the card-reader drives which are attached, but without a card inserted. This is a pain to deal with every single time a File Browser or World | Save As dialog is opened. Could the alerts either be - only raised when that specific drive is requested by a user action or, less preferably - given by a non-modal window, and fading away after a period" I was able to reproduce this error on squeaks and pharos window vm. (insert a usb card reader, with card, wait some time , remove only the card, every access on this drive, for example open a FileList and scroll to the drive letter). The solution I found is to call SetErrorMode( *SEM_FAILCRITICALERRORS)* I would like to propose the following change to sqwin32directory.c wrap the call to FindFirstFileW/FindNextFileW with UINT prevMode = SetErrorMode(SEM_FAILCRITICALERRORS); call FindFirstFileW/FindNextFileW SetErrorMode(prevMode); ... and call this functions in at least dir_lookup() (the other file/directory methods are save). Alternative solution, we could call the SetErrorMode function once at program start but I don't know if there are other "useful" errors message that we don't want to disable. I tested both solution, both seems to work fine. What do you think?

[Pharo-project] About ~= and ~~
by Clara Allende Nov. 26, 2016

Nov. 26, 2016

Hi guys, I'm wondering, why? ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." self == anObject ifTrue: [^ false] ifFalse: [^ true] Instead of: ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." ^(self == anObject) not And why? Object >> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^self = anObject == false Instead of Object>> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^(self = anObject) not. Is there any particular reason for this that I'm missing? Thanks in advance! -- "*Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program.*" Linus Torvalds

by Yuriy Tymchuk Nov. 16, 2016

Nov. 16, 2016

Hi, maybe someone can help me out with this. Iâm working with ListModel that supports multiple selection and has autoDeselect turned off. Now Iâve tried to use #whenSelectionChanged: but it doesnât give any data, #whenMultiSelectionChanged: is not triggered at all, #whenSelectedItemChanged: works as for single selection list. Iâd be very thankful for any help. Uko

GTInspector table hides columns
by Peter UhnÃ¡k Oct. 30, 2016

Oct. 30, 2016

Hi, apparently inspector is happy to hide columns if they don't fit. Why is there no vertical scrollbar? â Also (I know I brought up this in the past, but the problem still remains), why does "Description" takes up so much space even though there's no data at all? Why not cap it at the width of the heading? Thanks, Peter

Call for design for a literal programming doc similar to PythonDocTest
by stepharo Oct. 24, 2016

Oct. 24, 2016

Hi all I want something similar in the spirit to PythonDocTest https://docs.python.org/2/library/doctest.html I'm talking about basename "Returns the base of the basename, i.e. /foo/gloops.taz basename is 'gloops.taz' / basename is '/'" Pragmas do not work well i.e., basename "Returns the base of the basename" <expr: '''/foo/gloops.taz'' asFileReference basename' result: 'gloops.taz'> We should invent a syntax to be put inside comments and that we can easily parse because we need to improve the use and discovery of the library. I was thinking about basename "Returns the base of the basename" " '/foo/gloops.taz' asFileReference basename >>> 'gloops.taz' " Do you have any idea? I cannot not do anything and just complain that our methods are not that well documented. We as a community should take this and build an super cool system. I tried and defined >>> on Object to see if it works! Object >>> aResultingObject "If the method comment contains >>> then it is a pharo documentated test. We can check that it is true." " '/foo/gloops.taz' asFileReference basename >>> 'gloops.taz' " ^ self = aResultingObject Stef

moving to Rubric in Glamour
by Andrei Chis Oct. 3, 2016

Oct. 3, 2016

Hi, I moved Glamour to Rubric, deprecated those presentations that use PluggableTextMorph and moved almost all usages of presentations that rely on PluggableTextMorph. These changes are still only in the Moose branch to see if there are any ugly bugs. The changes to the glamour API are the following: - deprecated #smalltalkCode, #pharoPlayground and #rubricText - added #pharoScript If you use #smalltalkCode replace it with either #pharoMethod or #pharoScript If you use #rubricTest replace those usages with #text If you use #pharoPlayground replace those usages with #pharoScript (we changed this as the glamour playground is not the same at the GTPlayground and this was causing some confusion) For this I also renamed GLMPharoPlaygroundPresentation to GLMPharoScriptPresentation and GLMMorphicPharoPlaygroundRenderer to GLMMorphicPharoScriptRenderer. If you are using the latest moose let me know if you run into any problems or have questions. Cheers, Andrei

How do recover change with epicea?
by stepharo Oct. 2, 2016

Oct. 2, 2016

Hi i introduced a loop (yes totally stupid) in menu morph icon :) so I had to quit my image. I thought that epicea would show me all the changes and I could not find how to do it. I do not know how to invoke the old recover lost changes... so so far I lost 40 min of dev :( I have no idea what is monitor vs log set in Epicea. And log set is just with the changes I'm doing :( not the ones I lost :( In cutting alpha image it would be good to make sure that we cannot lose our work :( Stef

Do we need a special vm for testing sista bytecode backend? I enabled sista in the compiler settings and evaluating [ ] class crashes the vm. nicolai
