Launching PhyloclassTalk in different GNU/Linux distros

by HernÃ¡n Morales Durand

If you are using Linux, can you download and try to launch PhyloclassTalk? The software website is : http://phyloclasstalk.github.io/ You can find the installation procedure here: http://phyloclasstalk.github.io/doc/PhyloclassTalk-1.0.pdf If you are able to launch the software, you may paste the output of the following command: $ lsb_release -d or $ hostnamectl Thank you very much, HernÃ¡n

Mustache and section

by Hilaire

Hello, While iterating within a Mustache section is it possible to refer to a tag defined out of the list. For example, is it possible to do so: templateString := 'A list of numbers {{#list}} Number {{label}} : {{number}} <= #label in section {{/list}}'. context := { 'label' -> 'fine. 'list' -> { { 'number' -> 1 } asDictionary. { 'number' -> 2 } asDictionary. } } asDictionary to get output as: 'A list of numbers Number fine: 1 Number fine: 2 ' So far in my attempt the #label tag is not processed. Am I interpreting something wrongly? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Pharo + VirtualGPU on Parallella

by Sebastian Heidbrink

Hi folks, I dabbled around with the OpenSmalltalkVM and PharoV50 on the Parallella (https://www.parallella.org/) Although most OpenCL samples do currently not work, because of some issues with the esdk on the Parallella, I can at least report that this combination works. It might take some time until I figured the OpenCL errors out. The building of the kernels throws errors due to include path errors. The screenshot of my Pharo image on the Parallella through a ssh X forwarded session. Cheers! Sebastian

Re: [Pharo-users] GitFileTree on Pharo 5.0

Ciao, few days ago i encountered problems installing gitFileTree in pharo 5.0. The basic error is relative to the : External module not found. Someone considerations about it? > Hi Dario, > > this is good that you tested with Roassal. We have a more general issue... The same problematic is relative to Roassal. I install on the MacBook Pro OS/X 10.7.5 the sudo port install cairo But the error persist. Thanks for any help.

Re: [Pharo-users] BioSmalltalk win ...almost

by Johan Fabry

Yes, a +1 on the assessment of the paper. The research methodology does not really result in any representative or generalisable data, so the conclusions are unfounded. (I have no experience with the journal, but my gut tells me to stay away from it.) -- Does this mail seem too brief? Sorry for that, I donât mean to be rude! Please see http://emailcharter.org .

It would be nice to do as real benchmark between the different platforms on real examples.

Use of -> in Pharo Code

by Bruce Prior

Thanks for the explanation, Sebastian. It led me to look into associations and dictionaries, which led me to page 190 in /Pharo By Example/. The character, ->, is there used in examples. It is described as a message (I assume a binary message). I found -> also in the index under Object. Thanks again. Bruce

Re: [Pharo-users] Use of -> in Pharo Code

by Sebastian Heidbrink

Hi Bruce, in hsort again ;-) This was your code: > Teapot on GET: '/welcome' -> 'Hello World!'; start. Imagine it this way with brackets: Teapot on GET: ('/welcome' -> 'Hello World!'); start. This is the same as writing: Teapot on GET: ( Associtation key: '/welcome' value: 'Hello World!') ; start. Shorter: (x -> y) = (Association key: x value: y) The -> is the short version of the Association constructor. I hope this makes things a little clearer. Sebastian
