You see Pharo as a file syntax too. You did all that because you do not like you use the code browser but you should try it. because coding in the playground for now does not really scales.

Re: [Pharo-dev] How do recover change with epicea?

by Martin Dias

I'm back! Thanks for your feedback. I also didn't like the names... I was experimenting with new names that communicate better tools' meaning. In the middle of this experimentation I had release 8.0.2 with bug fixes, and those experimental names became public. Then, in this thread I understood that what was missing is explaining (or improving) the logs (ombu files) model... not finding super tool names. The new version of Epicea is waiting for integration: https://pharo.fogbugz.com/f/cases/19165/Integrate-Epicea-8-0-3 This version has the tool names proposed by Norbert and agreed by Stef, reported as: https://pharo.fogbugz.com/f/cases/19163/Improve-Epicea-tool-names and has a CustomHelp with the high-level documentation as proposed by Sven, reported in: https://pharo.fogbugz.com/f/cases/19164/Add-help-to-Epicea-project I also added "fly by help" in some buttons and didn't had an explanation yet. Stef, I didn't investigate if menu entries can have fly by help. The next Epicea version should have some improvement on this issue: https://pharo.fogbugz.com/f/cases/edit/19125/Epicea-Log-writing-is-very-slow Cheers Martin On Thu, Sep 22, 2016 at 2:25 PM, stepharo <stepharo(a)free.fr> wrote: > :) > > I'm trying to remember if we have fly by help on menu item because this > descriptions would fit nicely there. > > Martin the names proposed by Norbert are cool. > > > Stef > > > Le 21/9/16 Ã 13:00, Sven Van Caekenberghe a Ã©crit : > > Thank you for this clear explanation, Martin.

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

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?

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.

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

by CodeDmitry

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.
