Re: [Pharo-users] Pharo / J - Integration

Hi Stef Sorry, I didn't know the OOPAL paper until this evening :) I read through it very quickly, and I think it's a somewhat different approach I have to think about. To me the OOPAL concept looks like a smalltalk language extension, but with smalltalk oriented syntax, that is able to handle arrays in an easy and efficient way (without loops). The current Pharo/J integration is some sort of regular expression for math and array handling and manipulation from within Pharo. Personally I think the very compact (and sometimes cryptic) syntax of J is one of it's biggest advantages. It's not as easy to read and understand like smalltalk, but very efficient if you got some experience (like regex for strings). In my opinion, the OOPAL approach would be a set of smalltalk classes and methods which accesses an underlying array engine (like J). Please correct me, if I'm wrong. Currently, I'm unsure which approach is better. From a smalltalk point of view, the OOPAL approach is clearer. If you know both Pharo and J, it doesn't really matter. You can program all the enclosing stuff of a desktop- or web-application in Pharo, and just hack the number- crunching part (if there is one) in J. But again, I have to re-think about it ...

pillar latex mode
by Peter UhnÃ¡k March 9, 2015

March 9, 2015

Is there something like a latex mode that would convert to html? For example in wiki I can write <math>\int_a^b \! f(x)\,dx = F(b) - F(a).</math> and in html it will convert to an image. Peter

GitFileTree Version Numbering
by Sean P. DeNigris March 9, 2015

March 9, 2015

When copying MyPackage-Author-VersionNumber.mcz to an empty GitFileTree repository, VersionNumber is not considered, and it appears in the version browser as MyPackage-Author-1, which seems confusing. Could it keep the same VersionNumber? ----- Cheers, Sean -- View this message in context: http://forum.world.st/GitFileTree-Version-Numbering-tp4810543.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

calling block from within itself
by Peter UhnÃ¡k March 8, 2015

March 8, 2015

Hi, I want to use a block from within itself... is there a better way than passing itself? Is there something like self/thisContext I can access? right now I can do =============== transformTree := [ :root :block | root children do: [ :each | each doSomething. block value: each value: block ] ]. transformTree value: myRoot value: tranformTree. =============== Thanks, Peter

ZnClient --data {}
by Sabine Manaa March 8, 2015

March 8, 2015

Hi , I want to write the following command in pharo: "curl -v -X POST --data '{""email"":""mail(a)gmail.com"", ""password"":""geheim""}' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Authorization: BEARER d0ae3333-eaad-4335-a64b-8903470baa9f' 'https://user.gini.net/api/users'" The following does not work, response is 415 Unsupported Media Type text/html;charset=UTF-8 2341B And I assume that it is the "--data {}" part, which is wrong. ^ZnClient new systemPolicy ; https; host: 'user.gini.net'; path: 'api/users'; headerAt: 'Content-Type' add: 'application/json'; headerAt: 'Authorization' add: ('BEARER {1}' format: {self getAccessToken}); headerAt: 'Accept' add: 'application/json'; contents:'--data {"email":"mail(a)gmail.com", "password":"geheim"} '; post. how can I put the --data part into the request?

Reading an SQL db on OS X
by Alexandre Bergel March 7, 2015

March 7, 2015

Hi! I would like to read a SQL .db file. The page http://smalltalkhub.com/#!/~PharoExtras/NBSQLite3 mention how to do this on Windows and Linux, but not on OSX. What should I do to read a SQL file on OS X? I tried google, but it did not work.
