TDD facilities: missing ctrl+t

by Alex Schenkman

Hi list, I've installed the TDD-Facilities package. Pressing ctrl+t, or ctrl+r does not run the test, :-( I'm pressing it while editing a test method, in the default browser of a Pharo-1.1.1-OneClick image. Any clues on what I might be missing? Thanks again!

Where do I find KeyedSet?

by Alex Schenkman

Hi List, I'm trying to use the TestMock package in a Pharo-1.1.1-OneClick image, and it uses KeyedSet. Where can I find this class? Is there any tool to lookup which package in SqueakSource contains a specific class? Thanks in advance!

Re: [Pharo-users] squeak vm without MMU

by Javier PimÃ¡s

Well, I think it should be. In SqueakNOS we load squeak/pharo without libc and can work without memory management at all. The thing that should be tricky is were do you place things in memory, so you don't break other programs. Actually, for libc we implement just a minimal set of needed functions like printf, memcpy, etc (if you are interested you can look at our sqLibc.c file and the makefile which picks functions from glibc). For the functions you mention, I believe pharo can live without them, but of course you'll probably have to create your own platform with makefiles and tweaks. Also, libraries can be compiled as internal and that should solve most of the problems. Hope that helps! Javier.

Re: [Pharo-users] Finding RB parse tree rule for replacements

lukas it would be great if you could write some blog entries on RBWriter and that we turn that into a book chapter.

Re: [Pharo-users] [Pharo-project] Updated ConfigurationsOf...scripts?

by Dale Henrichs

HernÃ¡n, It _is_ possible to write some scripts that could automate the checking: ConfigurationOfXXX project updateProject loads the latest version of the mcz file for the configuration. Then you could write a little script like: | project | project := ConfigurationOfXXX project. project updateProject project currentVersion < project latestVersion ifTrue: [ self inform: 'A new version of ConfigurationOXXX is available' ]. to simplify the check for new versions a bit more...you could even automate the load of the newer version if you were brave:) Dale On 01/12/2011 01:56 PM, HernÃ¡n Morales Durand wrote: > Yes thanks. > notice there are 80+ ConfigurationOf... in the MetacelloRepository and > so many not listed there > > 2011/1/12 laurent laffont<laurent.laffont(a)gmail.com>: >> Isn't what you're looking for ? >> http://book.pharo-project.org/book/PharoTools/ >> Laurent >> >> On Wed, Jan 12, 2011 at 8:44 PM, HernÃ¡n Morales Durand >> <hernan.morales(a)gmail.com> wrote: >>> >>> Ok if there are not, I think is a must, I spend a lot of time >>> searching for the updated scripts or exporting/importing them in my >>> images.
