Thank you, Alistair. That worked fine for me in 64bit Ubuntu 18.04. In addition I'd like to have the same as Windows installations Windows 7 (32 bit and 64 bit) and Windows 10 (64bit) Is there a list of the allowed download URLs? --Hannes On 10/5/18, Alistair Grant <akgrant0710(a)gmail.com> wrote: > Hi Hannes, > > It depends a bit on the platform.

If you have done a PRISM PP parser, maybe you can contribute it to the PP community. Thank you.

Zinc-AWS - problem writing bucket, ZnAWSS3RequestSignatureTool old or how to change authorization mechanism

by Sabine Manaa

I try to save data in amazon s3 by using Svens package 'Zinc-AWS'. I created a bucket in s3 and can read it from pharo. But when I want to save data from pharo the requests response is <?xml version="1.0" encoding="UTF-8"?> <Error><Code>InvalidRequest</Code><Message>The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.</Message><RequestId>....</RequestId><HostId>....</HostId></Error> I see that ZnAWSS3RequestSignatureTool uses (HMAC on: SHA1 new). Here I have problems to go further and do not know if/how I have to change the authorization mechanism. Or is the ZnAWSS3RequestSignatureTool old? Anyone having a hint or working code snippet for me? Sven could you perhaps have a look?

Hi Hannes, It depends a bit on the platform. For linux 64 bit: curl get.pharo.org/64/70+vm | bash HTH, Alistair On Fri, 5 Oct 2018 at 01:28, H.

Spec Layout Help

by Rob Rothwell

Hello, How might one achieve a fixed width column containing fixed width widgets within a resizable row using Spec Layouts? For example: <--- Resizable Space --->| Fixed Width |<---Resizable Space ---> Where the Fixed Width space might have something like a left justified input field and a right justified button or something. The best I can achieve is everything resizable, which Spec excels at! I have tried adding three columns to the row with the center column a fixed width (newColumn:width:), but I can't seem to get it centered. I have even tried adding dummy widgets as in the code below, which creates a resizable column taking up the first half of the space, followed by a fixed width (100) input field, followed by another resizable space (sharing the right half of the column with the fixed width column): LayoutPractice>>defaultSpec ^ SpecColumnLayout composed newRow: [:row | row newColumn: [ :col | col add: #spacer1 height: 30 ]; newColumn: [ :col | col add: #inputField height: 30] width: 100; newColumn: [ :col | col add: #spacer2 height: 30 ]; yourself ] height: 50; newRow: [:row | row add: #list ]; yourself If this is not possible, could I allow the window to resize vertically but not horizontally (I have a ListPresenter below problematic row which would be nice to resize vertically)? Thank you, Rob

Re: [Pharo-users] [vwnc] Parsing in Smalltalk

Hi, Interesting experiment. Thanks for sharing! I assume that you tried the original PetitParser. PetitParser2 offers the possibility to optimize the parser (kind of a compilation), and this provides a significant speedup: https://github.com/kursjan/petitparser2 Would you be interested in trying this out?
