Just for your information, I have already implemented a REST service for accessing any Moose model and its objects: http://smalltalkhub.com/#!/~VincentBlondeau/MooseOnWeb. It uses Zinc-REST framework to implement the service. Feel free to contribute or ask more information!

Re: [Pharo-users] SmaCC: First steps

by kilon alios

Ok thanks for the info, I am still however curious about these "tests" are just tests (which may or may not happen) that determine the AST, for example which node to use ? Or are they tests related to unit testing class PythonParserTests ? Also you said I need to use the visitor created by PythonParser I assume you mean PyRootNodeVisitor ? Just as it is explained in the AST chapter of the documentation. In my case this simple python list will need me to subclass it and override method visitListmaker , the aListmaker passed as argument to the method should I assume it is PyListmakerNode ?

Re: [Pharo-users] how to debug zinc server errors from tests

by Ben Coman

If there is a particular test you want to run outside of the test framework, essentially you reproduce TestCase>>runCase in the Workspace. For example... MyClassTest new setUp testMyTest and you can wrap that in a fork. cheers -ben On Fri, Jan 30, 2015 at 5:11 PM, Martin BÃ¤hr < mbaehr(a)email.archlab.tuwien.ac.at> wrote: > Excerpts from Sven Van Caekenberghe's message of 2015-01-30 07:59:00 +0100: > > > when debugging a zinc server with tests structured as in > > > http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ > > > i am wondering how to best debug errors in the server while running > tests. > > > > > > one test makes a ZnClient connection to a testserver started from the > same test. > > > the test fails with the server returning a 500 error. > > Writing a unit test using both an HTTP client and server is already a bit > > tricky sometimes, having it fail is always ugly.

Re: [Pharo-users] Implementing text navigation shortcuts

by Tudor Girba

Rubric is basically a clone of TextMorph that was significantly refactored by Alain. Just keep in mind that Rubric is just a bridge solution. The goal is to adopt TxText as soon as possible.

Can Rubric be used for displaying paragraphs etc ? I want to improve the documentation situation for pharo by improving the help tool. Nothing major just something that will improve the general look. Shortucts also play a huge role in this, I really like Emacs documentation system that allow you to navigate via shortcuts .

Rubric is already in the image and has most of these keybindings properly defined.
