Re: [Pharo-users] The best way to construct a file/url path handling misplaced $/ chars

by Esteban Maringolo

I don't know whether you want to build just "paths" or valid URIs, if it's the latter, I'd suggest ZnUrl as well. '/name/' asPath / 'resource'. -> /name/resource '/name/' asPath / '/resource'. -> /resource (which is correct) '/name/' asUrl / '/resource' -> /name//resource (which is correct as well). The other way is to use path segments, as CÃ©drick suggested. Regards, Esteban A.

What is the pharo days code?

by Tim Mackinnon

Anyone know what is my code to use for Pharo Days registration? I got my member confirmation but have no idea what the code is all about that it wants for the Pharo days registration? (I recall this happening a few years ago but didnât pay attention) Any ideas? Tim

The best way to construct a file/url path handling misplaced $/ chars

by Tim Mackinnon

Iâm sure we have something in the image that deals with this - but if writing a generic http retriever and wanting to correctly cope with constructing resource paths where the base path may or may not have a trailing /, and the resource path may or may not have a leading / Basically - magically handle /name//resourse /name///resource Iâm sure we have something simple - the best I could see was to abuse Path like: (Path from: basePath, '/', resourcePath) pathString Is this a good way to do it?

ldap, Pier3 & git migration

by Albrecht Baur

Hi, In case someone can use it: I used Peters git migration tool for ... http://smalltalkhub.com/#!/~PharoExtras/LDAP/ ... and put it to: https://github.com/a2b-alb/PharoExtras-LDAP I don't know if this is the right place or if you would rather have it under ... https://github.com/pharo-contributions/ ... or somewhere else. ------------- here the question: I started trying to do the same migration process for ... http://www.smalltalkhub.com/#!/~Pier/Pier3 ... but I failed on errors loading older mcz files: "instance of ByteString did not understand #peek" on: MCMczReader >> contentsForMember: (ZnInvalidUTF8: Illegal leading byte for utf-8 encoding) Is this wrong encoding or corrupted files ? How to treat these files ? -> Is just ignoring this majority of failing mcz files via migration ignoredFileNames: #() ok ? ------------- As a workaround I then left the history versions behind and took only the newest mcz files. But I am not sure which package version "is in harmony" with the other ones...Â ;-) -> While trying out which versions of the ConfigurationOfPier3 load in a p7 image only the #stable one loaded without problems. The newer ones didn't. I did this by first loading as much pier3 dependencies (seaside, magritte, ...) from the new github repos. So I can then say ... onConflict: [ :e | e useLoaded ]; ... when loading pier3 from smaltalkhub. Can someone who knows pier3 better than me, give me a hint on which package versions combinations are the ones to go with ? -> Is to just start with the newest mcz files the way to go? Or should I use the #stable ConfigurationOfPier3 ? best, Albrecht

Lightweight name spacing or shadowing - anything that can help me load conflicting code?

by Tim Mackinnon

Hi - as I work through the different strands fo exercism (which has been a great project to kick different corners of Pharo) - Iâve hit an area where Iâm wondering if there might be some useful tricks/techniques/ideas to help â¦ Essentially - I want to make mentoring easier (so hopefully people on this list might consider being a Pharo Exercism mentor). While there are basic review tools on exercism.io - reading code in Tonel only gets you so farâ¦ So there is an endpoint for mentors to load in code (much like we already read in the exercises for users, and then use the TonelReader to parse and compile the code so its ready to run - a nice property of recent Pharo changes is that its quite happy to compile missing classes/methods and let you later fill those in, inside the debugger - it makes TDD awesome). However - it would be nice if mentors could have the current solutions loading in an image, and then could load in the users submission (via a tool hitting the endpoint - and doing the same TonelReader stuff). The issue of course is that you have a name clash - their solution and the reference solution. So I could possibly walk the ast of the parsed solution and adjust the names (putting a user prefix) - and possibly the refactoring tools will also let me detect references to those names and then let adjust those too (I also will have the thorny issue of extension methods - although its a rare edge case I could ignore). But Iâm wondering if there is something neater that might work? Can I load these as âshadow classes/methodsâ somehow (when you browse Monticello package versions I recall you could see code in a browser - and I guess iceberg does that too?). This might work - although it doesnât let me run the code and see any errors - but it might be good enough. Or is there some way of having a cheap alternate Smalltalk context where I can load that code so it doesnât collide. I guess this is edging on full namespaces - but I think my problem might be more confined and possibly doable more easily (than a general namespace solution that has to work for everything). Anyone have any thoughts - pointers? I know namespaces is very controversial, but maybe this might be simpler? Tim

I agree, that is an excellent option. "NLTK is a leading platform for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources <http://nltk.org/nltk_data/> such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, wrappers for industrial-strength NLP libraries, and an active discussion forum <http://groups.google.com/group/nltk-users>." Thanks for pointing NLTK. Great tool for sure. I agree that there no point in reimplementing but in this case of NLP, this might worth it as I think we have already all good foundations (Basic string manipulation, PP, Zn, XML, etcâ¦). The hard stuff is probably the integration of 100 corpora and lexical ressources (http://www.nltk.org/nltk_data/) The thing is I need a lighter version, based on my own (growing) corpora (my experience). So Hernan solution, PP, or straight string processing would do the job. But thanks, this is something I will explore too (especially the luges ressources).
