Keeping packages up to date

by Andrei Stebakov

I wonder if there is a generic solution to keeping certain Pharo project in sync with development tree. For example when I want to get latest Roassal I execute Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'Roassal2'; package: 'Roassal2GT'; package: 'Trachel'; load. Also I wouldn't know this unless the maintainers (thanks Alexandre!) of the project told me what script to execute to get the latest version. If I went to Project Catalog I can only get the stable version and if I go and find Roassal2 it won't give me information how to get its latest version. How would I get info about how to update, say Roassal given the script above from some Roassal project public page? Talking about Roassal, if I go to http://smalltalkhub.com/#!/~ObjectProfile/Roassal2/ page, it offers the following script: Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configurationOf: 'Roassal2'; loadDevelopment Which is probably not exactly equal to the script above (or is it?). So, is there a generic way to get a latest version of some XYZ package? What do I need to learn to be able to get that information about any Pharo project (other than asking the community)? Something similar to "git pull" when you know the repository.

@m_m#3045 for concurrency without shared state, running on a single green thread (smalltalkâs Process) with support for remote async sends to other images, there is my Raven [1], using Cryptography [2], ParrotTalk [3] and STON. This is an implementation of erightâs [4] ELib.

Re: [Pharo-users] What are RBPattern* classes in the AST?

by Thierry Goubier

Hi Steven, Le 31/03/2018 Ã 20:36, Steven Costiou a Ã©critÂ : > Hi, > > i was browsing the classes of the AST and i am curious about the > RBPattern* classes. > What are they used for? They represent metavariables in pattern trees when you use refactorings. Each pattern node specify a type of AST subtree that may be in that place when you match some smalltalk source code against a refactoring pattern. Once matched, an unification is done so that you can refer to that metavariable content by name (for example, retrieve the top node of that variable subtree). > The RBPatternParser's comment says that it is used "to search and > transform source code". Exactly. > After looking a bit in the senders and class refs, it seems it is used > for refactorings and other stuff. Refactorings and searches. > But is that used at some point in code compilation? No. But they could be used... if you do source to source transformations when compiling, for example, you could use such patterns to rewrite the code before compiling it; SmaCC for one uses that (create generic methods, then scan all methods with a set of refactorings to rewrite an optimised version of the code, such as merging contiguous character equality tests). For reference, have a look at: https://www.slideshare.net/pharoproject/smack-behind-the-refactorings Slide 31 describes the RB specifics, and the rest of the slides describe more in detail where those pattern nodes are found and used.

What are RBPattern* classes in the AST?

by Steven Costiou

Hi, i was browsing the classes of the AST and i am curious about the RBPattern* classes. What are they used for? The RBPatternParser's comment says that it is used "to search and transform source code". After looking a bit in the senders and class refs, it seems it is used for refactorings and other stuff. But is that used at some point in code compilation? Steven.

Re: [Pharo-users] Namespaces and ASN1 types in Cryptography package

by Esteban A. Maringolo

Hi Holger, Cryptography package lacks a proper modularization, so you could load only the groups you need, e.g. ASN1 will only be needed if you load X509 (AFAIR). If Nortbert's ASN1 package is more complete than Cryptography's, then we whould either merge it or discard what's there and load Norbert's ASN1 package as a dependency instead. Regards, Esteban A.

Namespaces and ASN1 types in Cryptography package

by Holger Freyther

Hi, I was debugging some test failures and it turns out that my code defines an ASN1IntegerType and the Cryptography package (a dependency of MongoTalk which is loaded into my code) has such a class as well. Thanks to Epicea I could see which package added the method but now I have no idea how to resolve the problem. Mongotalk needs PBKDF2 for modern authentication... Could Cryptography use "ASN1-Model"[1] instead? This is a rather complete[2] ASN1 implementation and used in production for some years. Could the classes be prefixed? If not how can I instruct Metacello to not load a certain package? holger [1] http://smalltalkhub.com/#!/~NorbertHartl/ASN1/source [2] Rather complete parser for ASN1 files but only encoding/decoding for DER/BER (none of the modern ones like aper/uper
