Hi, PPBrowser uses Roassal which relies on the Athens canvas which requires FreeType fonts :). To fix this, you can go to Settings: - Make Use Free type ... true - Choose a Free type font as the default one. Or you can just use the Moose 5.0 image: http://moosetechnology.org/#install Or you can use some ready made setup script we have in Moose: Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; package: 'GT-Setup'; load. #GTImageSetupCommandLineHandler asClass activateWithoutSaving Cheers, Doru On Wed, Dec 31, 2014 at 2:10 PM, Hartmut <krasemann@acm.org> wrote:
Hi Jan,
since a while I get a MessageNotUnderstood on PPBrowser open after ConfigurationOfPetitParser loadDevelopment. Has to do with fonts. Debugger Stack fueled out can be accessed here: https://dl.dropboxusercontent.com/u/4548797/Debugger-Stack-StrikeFont-2014-1...

Hi,
Anyone experience with Athens can help with the first issue? TRLabelShape>>drawOn: seem to be somehow responsible, but I don't see into this :(
Regarding to the second issue, there are some cases, when one really needs a start rule, e.g when computing follow. Yet I updated the code so that it handles missing start rule a bit better.
Please, let me know, if you have some other ideas/suggestions/issues.
Regards, Jan

Hi to all,
I'm working with PetitParser in a Pharo 3 image. Until now I had to do without the PPBrowser which I loved in Pharo 2.
On forum.world.st I now found the hint by Jan Kurs to install all of the Petit suite:
"Configuration should be loaded like this:" Gofer new smalltalkhubUser: 'Moose' project: 'PetitParser'; configurationOf: #PetitParser; load.
"All the petit parser suite:" ConfigurationOfPetitParser loadDevelopment.
Apart from the fact that this installed a real lot into my image, I notice the following problems in PPBrowser:
1. The map of none of the 18 parsers included, is displayed (it becomes red crossed). However, this was the most useful part of it
2. My interrelated parsers consist of a tree of parsers where each leave has its own start clause. They define related languages. It makes no sense to add a *start* clause to the root. However, without such a meaningless *start* clause, only the *source* is displayed, neither *graph, example, first* or *follow* of any clause. (this can be reproduced when you move PPJsonGrammar>>start to PPJsonParser)
I like the style of having a grammar class above a parser (or compiler) class. This is as seen in most of the accompanying parsers. My preferred petit parser style comprises: a) keeping grammar rules (without ==>) in the upper classes of the grammar hierarchy tree, such that we find the complete grammar there (without the *start* clause). b) keeping replacement rules (using ==>) as low as possible the grammar hierarchy tree c) writing the start clause to the class that is actually called. (this gives different entries in a grammar allowing for different languages with grammar subsets)
Is there an idea to have 1. and/or 2. resolved?
