Using MinGW is only a temporary solution. I asked Cyril to work on integrating what's currently in Bash scripts inside Pillar itself (e.g.,, iterating over input files, generating pdf from latex).

<example> pragmas and example* methods use-cases

by Peter UhnÃ¡k

Hi, there was a long discussion about the meaning of example* methods and <example> pragmas, however I do not know what was the final resolution. Basically I am interested in two use-cases 1. executable example (the one where Nautilus shows nice play icon) This is as I understand only through example* naming (on class-side). 2. returning examples (example that returns some value that I can reuse) Is this what <example> pragma is for? How would I go about naming it considering that having play icon there would be counter-productive (user would be clicking on it and nothing would happen). Thanks, Peter

PetitParser ignorable parsers

by Peter UhnÃ¡k

Hi, is it possible to add such a parser that would consume input, but wouldn't return anything? Right now I do things like... MyParser>>rule ^ ($[ asParser, anotherRule, $] asParser) ==> [ :nodes | nodes second ] Of course when the rules are more complex, so is the block; however it seems that this is how it's done in the example parsers... So, would it be possible to add some kind of Null/Void/Ignore/Throwaway parser, that would consume the input, but would be omitted from the result? so the above method could be written as MyParser>>rule ^ $[ asNullPaser, anotherRule, $] asNullParser or MyParser>>rule ^ $[ asParser ignore, anotherRule, $[ asParser ignore or something else. Thanks, Peter

We changed the way extensions was generated because the previous way wasn't right.

With a bit of ternary logic which says that symbols are in three states: defined, undefined and unknown. First two require a context; third one applies if you don't have a context. Thierry

Re: [Pharo-users] Any YAML parser?

I suggest using http://forum.world.st/ for searching through mailing lists; using Google is often hit-or-miss (which even with all its neural networks and tracking me everywhere is still after years suggesting Pharaoh...) Anyway, there seems to be something http://forum.world.st/PetitYAML-td4803677.html If you are not familiar with PetitParser, there's a chapter about it in PBE2 ( http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/PetitParser.… ) Peter On Sat, Jun 20, 2015 at 4:10 PM, Julien Delplanque <julien(a)tamere.eu> wrote: > Hi everybody, > > I googled a bit for a YAML parser in Pharo but I didn't found anything. > > Does anybody wrote a YAML parser for Pharo? > > Regards, > Julien > >
