TaksIt tasks sequence: writing a file and reading it to add its contents to a domain object

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I think that TaskIt is addressing a reader I'm not. Maybe I lack the previous background to fully make sense of it. I have been asking on Discord and getting some help to understand the rationale behind TaskIt and why is not doing what I want, but still I can not make it to do it. I want to do something like this: |task1 := [ code to write tempFile on hard disk using external Unix tools] future. taks2 := [ code to read data on the tempFile and add it to myObject dictionary] future. taks1 andThen: task2. myObject dictionary "Should show data coming from combining task1 and task2 y sequential order"| myObject is being changed in a future result that I can not access outside the block where I modify myObject. I would like to order task in a sequential order, doing the next only after the previous have ended and have access to the result of the last computation outside such sequence. Is this possible with futures? Thanks, Offray ||

Re: [Pharo-users] I think I've discovered an error in the later v9 builds

by Russ Whaley

Thanks Ben, I'll head over to the link tomorrow. I have done a bit of testing and have been able to isolate in which build the error(s) were introduced. I have yet to follow through the debugger and determine what's going wrong. It looks like something was (attempted to be) fixed with the sorting of the columns that jacked up the clicks for the transmitTo: transform: ... but that's just a guess due to the number of errors around sorting and transmitTo:/transform: I was able to use a Smalltalk method to get what I needed on which build I was using - good to know about the System Reporter as well.

glamorous toolkit & pharo

by Tudor Girba

Hi, As Glamorous Toolkit gets closer to being released, we get quite a number of questions on various channels about its relationship with Pharo. Glamorous Toolkit is built with Pharo. It is unlikely that we would have been able to produce it in any other language within the constraints we faced. At the same time, Glamorous Toolkit is a separate project produced by feenk with a distinct goal and its own realization. Here is a short overview of what we mean by it: https://blog.feenk.com/glamorous-toolkit-and-pharo-5aufgcequ38az2s0dj0t1nu0… Please do let us know if you have concerns or questions. Cheers, Doru -- feenk.com [fiËÅk] verb feel and think concomitantly.

Re: [Pharo-users] Output the method name as a string at runtime

by Ben Coman

Sorry for the slow response. Perhaps you've already worked it out, but anyway a few options... You "could" pass thisContext as a block parameter initialize errorBlock := [ :tPduError :aContext | Error signal:'Method: ' , aContext selector asString , ' with result: ', tPduError item asString ]. pduDestruct result = T_PDU_ERROR PDU_STATUS_NOERROR ifFalse: [ errorBlock value: result value: thisContext ------------------------------------ But rather I suggest a better option is to separate this logic into its own error class... Error subclass: #PduError ... instanceVariables: 'result selector' PduError class >> result: aResult context: aContext ^ self new initializeResult: aResult selector: aContext selector asString PduError >> initializeResult: aResult selector: selectorString result := aResult. selector := selectorString PduEror>>messageText as you like - refer to other implementors for example PduError>>printOn: as you like - refer to other implementors for example pduDestruct | result | result := call ffiPDUDestruct. result = T_PDU_ERROR PDU_STATUS_NOERROR ifFalse: [ (PduError result: aResult context: thisContext) signal ] cheers -ben On Sat, 27 Jun 2020 at 22:56, ASAM <vmax28575(a)gmail.com> wrote: > Hello, > I would like to output the method name as a string in case of an error. > > what I've already done is this: (with thisContext selector asString) > > pduDestruct > | result | > result := call ffiPDUDestruct. > result = T_PDU_ERROR PDU_STATUS_NOERROR > ifFalse: [ Error signal:'Method: ' , thisContext selector asString , ' > with > result: ', result item asString ] > > > but now I use it more often.

Re: [Pharo-users] Pharo 9 Unicode

by Tomohiro Oda

TomaÅ¾ and Sven, I tested Pharo-9.0.0+build.469.sha.fcf155b2849b5b411091f5a7ea6014bf57ddf402 (64 Bit) that I downloaded by PharoLauncher a few minutes ago. It works fine if the code font and default font are set appropriately. The attached is snapshot of Playground with appearently higher than 255 codepoints. --- tomo [image: Playground.png]

That would be an unacceptable regression.
