Code diff between metacello versions

by Norbert Hartl

Is there a tool or a code snippet which can show a code diff (side by side) between the packages of two metacello versions? thanks, Norbert

Re: [Pharo-users] Useful tools?

by Tim Mackinnon

Laura - not sure if this fits your bill, but I really find that PharoLauncher is handy - it lets you easily download new Smalltalk images (maybe to track new features in Moose, or Pharo 4.0) - before using it I had things lying around where I had forgotten what they were for. This helped me put a bit of structure around things and try out new stuff when I saw it mentioned on these mailing lists. Its on: http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher (Itâs also a nice example of how to write a shrink wrapped Pharo application that looks quite slick) Tim On 15 Jan 2015, at 03:58, laura <laura.risani(a)gmail.com> wrote: > i'm afraid i posed the question too broadly to be answerable, so > reformulating... > > What are some tools you frequently use to ease development which are neither > built in the current official distribution nor domain-specific? > (for example i added TilingWindowManager, RBConfigurableFormatter, many > shortcuts ) > > Some Class Browser plug-in?

It's practical uses depend, more of less, on whether or not you are dealing with bytecodes or not. If you are the it's quite useful to see how values are being pushed/popped from the stack. Also the normal debugger executes multiple bytecode instructions at once.

As part of that we need a data structure that holds scopes, for variables but also for other things. It turns out that for the variables part we can map rather nicely to classes, which gives us a bunch of advantages. So for each scope I generate a class. The scope keeps that class in a âvarsâ instance variable (there are never any instances of these classes BTW). When the scope is garbage collected I want to remove the class from the system. So I put #finalize in the scope with the idea to remove the class, but it turns out that âvarsâ is always nil. So in the end it did not work out ... You're probably registering the scope for finalization before setting the vars insvar? The shadow copy is made at the point of registration, so any subsequent assignments to the scope's instvars is not accounted for. Cheers, Henry

wow nice, great job Andrei what are the practical uses for this debugger, does it also allow you change the bytecode as the regular debugger allow you to change code ?
