Different dialects have different features (e.g. Namespaces, Traits), syntax, image format... Smalltalk is a concept, with Smalltalk-80 as the canonical reference, not even a specification, because ANSI Smalltalk was the closest thing to a standard (Like ECMA TS39 is for JavaScript), but it was DoA. > This means between different distributions of Smalltalk (VA, Squeak, Pharo...)?

Smalltalk comes from a pre-opensource era, where commercial vendors were the norm, and competition was not collaborative as it might be now. Each one took its own path and merging everything back is non-viable, both for technical and commercial reasons. When/if smalltalk grows to a web scale, then the need for standards and constraint will arise. Regards! Esteban A. Maringolo

A little help with EnterprisePharo book

by Jonathan van Alteren

Hi all, I'd like to be able to build the EnterprisePharo book, so I might contribute to it with some improvements. However, the README seems to be out of date. The 'download.sh' file mentioned under 'Download Pillar' is not there. There's a 'subdownload.sh' file, but that doesn't do or output anything, and looking into it, the URL returns a 404 (https://raw.githubusercontent.com/pillar-markup/pillar/master/download.sh) So I manually cloned the pillar git project fromÂ https://github.com/pillar-markup/pillar. I checked out tag v7.7.4, since that was mentioned for Pharo booklets. Building that works, resulting in a pillar 'executable'. However, after installing MacText, executing 'pillar build pdf' fails with the message: FileDoesNotExistException: '/Users/jvalteren/git/EnterprisePharo/_support'. Looking at the structure created by the command 'pillar archetype book', it seems that '_support' is the new name for the 'support' folder that does. So, I created a symlink from '_support' to 'support' and tried building again, but that fails with the message: KeyNotFound: latexWriter. This seems to be related to the contents of the 'pillar.conf' file. Instead of trying to guess what's going on and try different things to fix this and get it built, I thought to reach out here :-) Can anyone tell me what to do so I can start making changes to the book? I'm on macOS Catalina by the way, so 64-bit only. Thanks! Jonathan van Alteren Founding Member | Object Guild B.V. Sustainable Software for Purpose-Driven Organizations jvalteren(a)objectguild.com

Re: [Pharo-users] Find/Replace class scoped

by Thierry Goubier

Hi Vitor, as a matter of fact, the infrastructure for doing what you're looking for is already there. The algorithm is the following: - create a scope (something based on RBBrowserEnvironment, such as RBClassEnvironment or based on regexes and AND / OR operations: RBAndEnvironment, RBNotEnvironment, which allows for virtually anything, such as all #printString methods in the package X that do not belong to class Y) - create a refactoring command: if it is not a pre-existing command such as rename class, etc..., then writing a pattern matcher is possible with RBTreeRewriter. - execute the refactoring command on the environment, changing only for the subset of code visible in the environment. Normally, the system browser or the search tools should automatically setup the environment for you, and scope accordingly most of the refactoring commands. As far as I know, there isn't yet a shell giving you the full pattern matching rewrite power, but some work was underway (GUI tools). Going with the source files as you did also work...
