[Pharo-project] Small polymorph suggestion
by Schwab,Wilhelm K March 21, 2012

March 21, 2012

Gary, I haven't figured out what they do yet, but I found #newSeparator, which creates a horizontal widget (name does not reflect this). Then I dug around and found #newVerticalSeparator. I suggest #newSeparatorHorizontal and #newSeparatorVertical, putting them together in the method list for easier discovery. Bill

Given pretty-printing there's no need for method text style. But in a class comment (if people knew it was available) it can be quite nice. > In Pharo right now all source is just a string... class comments, too.

Re: [Pharo-project] Any theme or settings that will speed up a Pharo 1.3 image?

[Pharo-project] Compiler bug!!!
by Igor Stasenko March 20, 2012

March 20, 2012

Here the simple method: at: index <primitive: 60 error: x > ^ x And its bytecode: <primitive: 60 error: x> 13 <81 41> storeIntoTemp: 1 15 <11> pushTemp: 1 16 <7C> returnTop Now, if i add this: at: index <primitive: 60 error: x > [:foo | 5]. ^ x I get following bytecode: <primitive: 60 error: x> 17 <81 42> storeIntoTemp: 2 19 <8F 01 00 02> closureNumCopied: 0 numArgs: 1 bytes 23 to 24 23 <20> pushConstant: 5 24 <7D> blockReturn 25 <87> pop 26 <12> pushTemp: 2 27 <7C> returnTop so, if we ignore the block closure bytecodes, we have: <primitive: 60 error: x> 17 <81 42> storeIntoTemp: 2 26 <12> pushTemp: 2 27 <7C> returnTop The problem is that for method context there are only 2 temps (argument + error code) .. but not 3 (index is zero-based). The fix should be simple.. in code which calculates the temp index for 'error code' temp. -- Best regards, Igor Stasenko.

Hello, i want to add some scripting capabilities to my app, and I wand to use plain smalltalk for that. The only problem is that I still haven't found a way to generate a compiled which would return a string describing a problem in case a syntax errors. Can I get some help? -- Milan Mimica
