Glamorous Toolkit as IDE for another language?
by Luke Gorrie Oct. 23, 2016

Oct. 23, 2016

Howdy, I am interested in building a Lua IDE using the Glamorous Toolkit. The idea is that the Playground, the Inspector, the Spotter, and the Debugger would all be interacting with an external Lua process instead of running code in the Pharo image. The "under the hood" part of Pharo - Smalltalk code - would be hidden unless specially enabled. Good or bad idea? Any tips on how to approach this? Has something similar been done before? (Is there example code available?) Cheers, -Luke

image shrinking and cleanup
by Peter Uhnak Oct. 23, 2016

Oct. 23, 2016

Hi, I know that I can cleanup the image with `Smalltalk cleanUp: true except: {} confirming: false.`, however that doesn't seem to help much. My guess is that there are some objects that the system is permanently unable to GC, however I have no idea how to find them (or even where to begin the search). Just as a note, the size of the image by itself is not an issue (I have plenty of disk space), however it is severly slowing down image saving. I remember that there was some issue with image shrinking, but I am not sure what is the state of that. Oh, and I am using Pharo 5. Thanks, Peter

Hi matteo Please open a bug entry and submit a fix and there is a good chance that your enhancements will be added to Pharo. We cannot crawl the mails and do that in addition to all the rest. :) Stef

Xtreams: Debugging Grammars
by Chris Cunnington Oct. 22, 2016

Oct. 22, 2016

>When I evaluate: > parser := PEGParser parserPEG parse: 'Grammar' stream: PEGParser grammarEmailAddress actor: PEGParserParser new. >I get: KeyNotFound: key 'quotedstring' not found in Dictionary >How am I supposed to debug that to find the typo in my giant string above?! Hi Sean, Your error is saying is that there is no key called 'quotedstring' in the dictionary in the grammar ivar of your parser. In each parser is a grammar ivar. It contains a dictionary. The values of the dictionary are graphs of compiled blocks. Each node of the graph is a block with arguments that are blocks that have arguments that are blocks, etc. It's a graph of compiled blocks. Try this. Add in PEGParser class. grammar3Names " a grammar to create a parser to sort three names as per page 24 of Grune's book Parsing Techniques (1990)" ^'Sentence <- NAME NAME <- "tom" / "dick" / "harry" ' Now execute this. (PEGParser parserBootstrap) parse: 'Grammar' stream: PEGParser grammar3Names reading actor: PEGParserGenerator new. That will show you the code that will create the dictionary in the grammar ivar. Now make a change. myparser := (PEGParser parserBootstrap) parse: 'Grammar' stream: PEGParser grammar3Names reading actor: PEGParserParser new. You generated the parser, not the code for the parser. To use the parser. myparser parse: 'Sentence' stream: 'harry' reading actor: nil Now let's look at the same thing in three ways. PEGParser>>#grammarPEG this is the grammar PEGParser>>#parserBootstrap this is the code generated by the PEGParserGenerator from grammarPEG PEGParser>>#parserPEG this is the parser returned by PEGParserParser from grammarPEG You will see that PEGParser parserBootstrap and PEGParser parserPEG are interchangeable anywhere. In fact, if the goal is to populate the grammar ivar with a dictionary to make a parser, then #parserPEG starts to grate on one's nerves, because you already have what you need in the grammar ivar by evaluating PEGParser parserBootstrap. #parserPEG compiles the grammarPEG using PEGParserParser into the grammar ivar to make a parser, but it's the exact same as what was already there. It's irritating. I'll release some examples in a package called Xtreamly some time before Christmas to help start understanding Xtreams-Parsing. HTH, Chris

[Voyage] Question about update of an object
by Cyril Ferlicot D. Oct. 22, 2016

Oct. 22, 2016

Hi! I have an application with Users that are voyage roots. Those Users can have a object X that is also voyage roots. I created a web application where a User can create an object X and save it. But now I want to adapt the component to edit an existing X object. What I have in mind is that I can copy the instance of X, let the user change it and save the changes if the user click on "Edit" or discard the changes if it click on "Cancel". But I don't know how really works the update in Voyage. If I send "save" to the copy of X, will it replace X inside the DB? Or should I create a method "updateFrom:" in X to change all his variable to match the ones from the parameter and then send "save" to the real X object? Thanks -- Cyril Ferlicot http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France
