Ok I got the proof of concept down, but I can't get it all to run at once since Pharo realizes that the class does not exist(at the time of running), even though it will exist by the time it gets to that line. Is there a way to modify the following Transcript code make the following code run "at once". Ignoring the fact that classes are not created at time of writing? ([ SimpleSwitchMorph subclass: #LOCell instanceVariableNames: 'mouseAction' classVariableNames: '' package: 'PBE-LightsOut' ] value).

Thanks Peter! I admit I couldnt really dynamically add methods to a class at runtime since I was doing it as follows: ([ (LOCell class) methodDict at: #mouseAction put: ((LOCell class) compile: mouseAction: a ^ mouseAction := a ). ] value). Which caused constant harassment by Pharo until I typed: (LOCell class) removeAllKeys. or (LOCell class) removeKey: #mouseAction. I'll try your method in a bit to see if it works better. -- View this message in context: http://forum.world.st/New-to-Pharo-a-bunch-of-questions-tp4917701p4917706.h… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Couple more answers. On Sat, Oct 01, 2016 at 09:29:51AM -0700, CodeDmitry wrote: > 3.

Yes and no, you can specify indent string in "Code Browsing > BlueInk Pretty Printing", however when you press "tab" it will still insert tab. This setting only applies to autoformatting. (ctrl+shift+f). As for class definition, the implementation is in ClassDescription>>definition, where you can see things like aStream cr; tab; nextPutAll: 'instanceVariableNames: '; store: self instanceVariablesString. so you would need to change >aStream cr; tab< into >aStream cr; nextPutAll: 'your indentation spaces'< Or you can do that en masse... newCode := (ClassDescription>>#definition) sourceCode copyReplaceAll: 'tab;' with: ''' '';'.

As a bonus in answer to "3." you can also see how to dynamically compile a method. :) Peter

Re: [Pharo-dev] New to Pharo; a bunch of questions.

I don't like tabs because I always have my code have 4 space indenting, so when I add 2 spaces to Pharo's spacing to 4, it (1) when I backspace 3 times, it effectively removes the 2 spaces and then the tab, then when I press backspace for the fourth time, it puts me back on last line rather than removing the fourth "character", and it throws me off a bit. (2) it removes the spaces I added, and puts tabs instead. People deal with complexity through patterns, and allowing them to choose what patterns work for them greatly reduces astonishment and improves code quality since code behaves the way the programmer expects rather than how the environment thinks the programmer should expect it to behave. I can get used to it but it's always going to bother me and throw me off in other environments when I do(context switching). Thanks so much for that comment about classes. I realize now that that expression not only to just be a simple expression (Object subclass: x1 instanceVariableNames: x2 classVariableNames: x3 package: x4), something I haven't realized; but it also creates the package if the package does not exist. I can now write Pharo-environment setup scripts that I can run in playground to set up the whole pharo environment(which I can give to others instead of image/sources/changes files. -- View this message in context: http://forum.world.st/New-to-Pharo-a-bunch-of-questions-tp4917701p4917703.h… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

New to Pharo; a bunch of questions.

by CodeDmitry

I have a course at my university where I have to use Pharo for assignments. I have a few questions about the Pharo environment. 1. Is it possible to turn off Pharo's "'" and "()" matching? If so how? 2. Is it possible to use system fonts in Pharo? If so how? 3. Is it possible to prevent Pharo from screwing up indenting of my class definitions when I save?(It keeps replacing leading spaces with a tab). If so how? 4. How can I create a Pharo package from Playground using code? 5. How can I create a Pharo class from Playground using code? I suspect 4 and 5 are possible because Pharo allows dynamic insertion/removal of methods from classes using the class method dictionary and runtime compile.

Hi. *In short: * normally you don't, but for some reasons right now you do. Try a VM from here <https://bintray.com/opensmalltalk/vm/cog/201609292318#files/> [1]. *In long:* Normally you need a VM with the following slang to C compilation settings: MULTIPLEBYTECODESETS true bytecodeTableInitializer initializeBytecodeTableForSqueakV3PlusClosuresSistaV1Hybrid which has been added recently to multiple VM builds, including the Pharo build if I am correct. The latest Pharo VM on files.pharo.org answers true to "Smalltalk vm supportsMultipleBytecodeSets", so it should be fine... But, when I tried to run code with new bytecode set, it does not work indeed. So... I've just compiled another VM to check and it could run the image. I've just checked with the VM from openSmalltalk <https://bintray.com/opensmalltalk/vm/cog/201609292318#files/> [1] and both pharo.cog.spur and squeak.cog.spur could run the Pharo image with both bytecode set and full blocks. It's not clear pharo.cog.spur is a complete Pharo VM as the migration process to opensmalltalk VM is still in progress, it may be a squeak VM with part of the extra Pharo plugins. I believe something is temporarily wrong during the opensmalltalk pharo vm migration. I would recommend to use a VM from bintray to test those features until the migration is over. On the openSmalltalkVM git <https://github.com/OpenSmalltalk/opensmalltalk-vm> [2] you have a link by clinking "download" to the latest bintray releases. Those releases are built automatically and very frequently.
