[Pharo-project] About validating the result of RBParser >> parseMethod:
by Fernando olivero July 23, 2010

July 23, 2010

I have a question about validating a methodNode, suppose we have the following: parsedNode := RBParser parseMethod: 'test ^ self add: anUnbindedVariable'. Is there a way of checking the health/validity of the parsedNode? I couldn't find any behavior in RBMethodNode or related classes. Lukas, do you have an idea is i could run any Lint rule? My idea is to provide a method editor morph, that prevents from accepting invalid sources, and informs the user any problems detected with the edited code. Thanks, Fernando

[Pharo-project] Literal array with evaluated value of stmts, vars etc..
by Sudhakar Krishnamachari July 23, 2010

July 23, 2010

Would this be of interest in general... I have always wanted a more capable literal array than what we have now.. #( 123 23 'das' ) whynot: #( 'ac'->23 2->'casd' myVar1) ... evaluates to a collection.. so I just tried this out with a BlockClosure: asArray | stmts anArray | stmts := self decompile statements. anArray := Array new: stmts size. stmts doWithIndex: [ :eaNode :indx| | start end value| start := (eaNode asString indexOf: ${)+1. end := (eaNode asString lastIndexOf: $})-1. value := Compiler evaluate: (eaNode asString copyFrom: start to: end) for: self receiver logged: false. anArray at: indx put: value]. ^anArray So we could do: ['abc'->123. 'def'->456. 'efg'->789. 'hij'->123. 'klm'->456.] asArray. [self checkThisUsingKeywordMethod: 'abc' with:'efg'. localVar1. instanceVar1 ] asArray to yield arrays.. not neat, I would much rather prefer the literals do their job their way... but works.. for the narrow set I have tried so far.. Any comments.. -Skrish

[Pharo-project] State of Sound in Morph
by Hilaire Fernandes July 23, 2010

July 23, 2010

I tried the Pharo sound package, so far it looks sound is not working. Is it true or is it a mistake of myself. For example: No sound output when executing: FMSound bass1 play DNU FMSound copy when executing: (FMSound lowMajorScaleOn: FMSound bass1) play Hilaire

Right-click on a protocol -> The method Boolean and:and: has been deprecated. use and: Culprits: - O2CmdExcludeClass>>isActive - O2CmdTestPackage>>isActive - O2CmdTestClass>>isActive - O2CmdExcludeMethod>>isActive I fixed them in my image. Do I publish a new O2-Enhancements package on SqueakSource or do you want to reapply the fixes i.e. simply put () where necesarry. -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

[Pharo-project] Squeak devices and applications
by Torsten Bergmann July 22, 2010

July 22, 2010

Just read the post from Hilaire about Pharo on OLPC [1]. This leads to the following interesting question: What is the most crazy device Squeak VM is running on? What is the most interesting application where nobody would have expected Squeak/Pharo/Cuis? Feel free to answer by posting screenshots/pictures even if you think the device/app is boring. Would be nice to know and we can collect these to do a little bit of advertising on the Squeak/Pharo web pages... Bye T.

Hi! Time to time, I need to create a #name method on my class. But I found a bit ugly to do an override. Is Object>>name that important? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Pharo-project] about hex
by stephane ducasse July 22, 2010

July 22, 2010

If I recall hex was removed because it was used for html related thing. Stef Looks like the hex method will be changed in Squeak and we should keep track using this issue to see if Pharo has to follow to keep compatible (also for Cog).
