The warning messages were added at that time. I'm happy either way, although I do think that some kind of message encouraging folks to consider other services is still appropriate. After all, we are not trying to attract a lot of new users to squeaksource.com, the emphasis is on maintaining the reliability and availibility of the existing service. > > PS -- we should ask Pharo if they prefer to have "and Pharo" removed > too so it doesn't create confusion for their users if have moved on > from Squeaksource. The squeaksource.com service is quite actively used by the Pharo community. Maybe we get get some input from the Pharo perspective (this message is cross posted to both lists). From my point of view, it seems good to say "for Squeak and Pharo" here. Dave > > On Mon, Aug 3, 2015 at 5:54 PM, David T.

I strongly support that. The PostgresV3 integration in Squeak uses that, and I want that for ATDD support (Features, Scenarios, Goals, Stakeholders) Stephan

It depends on how the system browser is implemented, but it sounds doable. I would be able to do that fairly easily on AltBrowser, since commands (all menus and shortcuts, including refactorings) are delegated to the node you are using (i.e. the class, the method, the command) in the browser. Syntax coloring is sort of keyed to the node (i.e. a comment node doesn't do syntax coloring the way a method node does). > I am talking about another syntax that would be parsed to the same AST > for now, though as the compiler can be changed too, I guess a complete > separate compilation chain and AST could work fine if the AST has common > APIs with RB for the refactoring browser and syntax coloring. No, that wouldn't work for refactoring. I believe RB apply refactorings by source code changes, and so it would introduce the old syntax in the middle of the new. If you use a SmaCC-based parser for the new syntax, then you would get along the refactoring engine for that syntax and AST. Writing a syntax coloring tool from a Parser is extremely easy, independently of the way this parser is implemented. It can be auto-generated; I did some experiments with Usman on that, and they were very interesting, in particular about the speed of the resulting syntax coloring tool. > What do you think ?

Re: [Pharo-dev] Multiple syntax support in Pharo

by Jan Vrany

Hi Clement, I have done exactly this a long time ago. I went even further, allowing different methods being written in different languages (so one could have a class with one method in Smalltalk, other in Java, third in JavaScript, fourth in Ruby or even LISP) Now, fiddling with parser/compiler was actually the easiest part. The hard (though not "difficult") part was to make it working so one can commit and load back the package smoothly, senders / implementors work as expected, debugger is not confused, inspector still works and uses the right compiler for the object, changes are written properly and could be actually loaded back. Myriads of little details... And yes, as soon as "the other language" semantics differ from Smalltalk, you expose yourself to a number of interoperability issues, depending how much different it is. Some of these problems are easy, some of them tricky. Most of them tricky :-) So better stick to Smalltalk semantics... And what is the worst :-) even if you manage to make it up and running, then only to find out that "ordinary" programmers don't like it. They want only one language to rule them all. How many times I have heard "I don't like programming in this or that, I want program everything in Smalltalk (substitute for your favorite)". So, be prepared. If you'd still give it a go, I'd be happy to discuss details. My 2 cents.

Instability. Git commands fail, and, since GitFileTree uses a few of them, GitFileTree becomes unusable. > Why is the command executed in a shell? Because the OSProcess version was also executing in a shell (and so, by default, the git command had no path). In the current version, the git command has a path and the OSProcess side doesn't use the shell, so it could be the same. Should it be changed for ProcessWrapper as well?
