Not sure if you're still stuck but if you dive into evaluate: you'll be able to find the point at which it parses, and find out how to invoke the parser for an expression (a doit). evaluate: parses an expression so you want to check that the resulting parse tree is that of a return node whose expression is a literal block. You can also check the block's argument count. Once you've extracted the parser invocation you can wrap this in a suitable exception handler. Then you have your block parser. You still have to validate the parse tree and/or generated code before evaluating since someone could write malicious code within the block right? > > Thanks in advance > > -- > Mariano > http://marianopeck.wordpress.com

Re: [Pharo-dev] Add JSONSchemas to NeoJSON

by henry

To be honest, I looked at Fuel, but it has changed: I can't find the FLDecoder. I had hoped such a framework could switch to JSon encoding, as the substitution framework is robust. I do not know if it's feasible. - HH On Sat, Aug 12, 2017 at 19:09, henry <henry(a)callistohouse.club> wrote: > I also need callbacks for substituation during encoding, SAX-like.

I also need callbacks for substituation during encoding, SAX-like. I think custom mapping of NeoJSON does this, with clusters.

[ann] moldable editor - syntax highlighting ... with a twist

by Tudor Girba

Hi, After another intense week, we are happy to announce that the Brick editor now supports some advanced syntax highlighting. To put it in perspective, let us take a look at one screenshot showing an inspector presentation containing a Brick editor opened on a Pillar file that includes some text, a code snippet and a reference to a picture: This shows both that we style the text based on the Pillar grammar, but also that we can style Smalltalk code (in fact, we have two nested stylers here). But, the more interesting thing is that below the picture reference, we get to see the actual picture (which happens to be another inspector screenshot). In fact, this picture is actually just another text attribute (we call it an adornment) that can be dynamically added to any text elements. This opens up a whole lot of expression power and it is all easily compose-able. This is another reason why we say that this editor is moldable and you should expect new applications making use of this moldability and combining it with the liveliness of Pharo. The latest Brick code is loadable through: Metacello new baseline: 'Brick'; repository: 'github://pharo-graphics/Brick/src'; load: #development. If you want to play with Pillar, load the following extra code and just inspect a Pillar file: Metacello new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration: 'Pillar'; version: #development; load. ((IceRepository registry detect: [ :each | each name = 'Brick' ]) packageNamed: 'Brick-Editor-Pillar') loadLatest. One other thing to mention is performance. What Alex (Syrel) managed to do is quite remarkable. To see the impact in practice, try editing the largest method in Pharo (UnicodeDefinitions class >> #data) in both the built-in editor and in the Brick editor by inspecting: BrTextEditor onMethod: UnicodeDefinitions class >> #data There are still issues left to deal with and we will focus on them in the following weeks. But, we can safely say that the most important challenges are now behind us and that the design of the editor code is stable and robust. Please do let us know what you think.

Anybody using Orca Smalltalk to JavaScript?

by Frank Berger Software

Hello, the available documentation on Orca looks brilliant and the source, Hasso-Plattner-Institut in Potsdam, has an excellent reputation. It looks all very professional. I am therefore most suprised that I cannot find any tracks of usage of Orca, neither here, nor elsewhere on the net, and not even any serious discussions. Does anybody here have practical experience with Orca? Critics? Recommendations? My goal is to use it for a real-life business application rather than the ST2JS, which would be the second alternative. All of my server software is written in Smalltalk anyway. Thank you in advance for any comment. Frank

recent slowdown of files.pharo.org and smalltalkhub

by Peter Uhnak

Hi, does anyone know what is the reason for the recent slowdown of downloading (latest) images from files.pharo.org? I had travis builds timeout on this (downloading images for 10+ minutes, etc.), and was several times unable to download new images even locally. Thanks, Peter
