Now when you click on the package in the browser, you can see that the repo is included in the list to the right (which initially only lists the package-cache. This is a one-time operation to set things up. As you discovered, to save the package to that repo, you select both and click "Save".

Re: [Pharo-project] Ehh??? cannot fileout with Nautilus and RPackage?

by Benjamin

It should be implemented, but since I have no knowledge about RPackage, I can't do it. If you remember being to file out packages from Nautilus, it was in one or your dreams :) (and I am pretty proud that your dream about Nautilus ^^) Ben On Apr 19, 2012, at 5:44 PM, Mariano Martinez Peck wrote: > > > On Thu, Apr 19, 2012 at 5:41 PM, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On Apr 19, 2012, at 5:40 PM, Mariano Martinez Peck wrote: > > > fileOut > > > > self error: 'I should be implemented somehow' > > > > mmmmmmm > > It's not yet finished... else it would be in 1.4 :-) > > > :( but at least it should be able to get an dummy PackageInfo or something to be able to file out...it is not good not to be able to file out your code. > In fact, I remember being able to file out packages with Nautilus..so something has changed. > > Marcus > > > -- > Marcus Denker -- http://marcusdenker.de > > > > > > -- > Mariano > http://marianopeck.wordpress.com >

Re: [Pharo-project] The video about Athens

by Denis Kudriashov

It's so great stuff!!! :)) Is cairo used as athens backend for this demo? Is it should work with Bitblt backend? In demo I see many usage of angel parameter for transformations. Do you think about "angel unit objects" like "90 degrees" or "2 radians" instead of raw numbers ? How #scaledBy: works with Point argument (self extend) and Float like (frame / 100 sin abs) at the same time? What' logic?

[Pharo-project] Using Monticello

by blake

Separate of Seaside, I decided to try to figure out how Monticello is supposed to work so I could then report back on what's wrong in the Seaside Dev book and I came across this video from Ramon Leon on how to use Monticello. http://onsmalltalk.com/screencast-how-to-package-smalltalk-code-with-montic… ...and I get hung up in the exact same place! 1. I created a category called "AAA" and made a class called "AAA1" with a single method "someMethod". 2. I opened the Monticello browser. 3. I added the package "AAA" to the Monticello browser. 4. I browsed the package "AAA" from the Monticello browser, which was reassuring. 5. I added a repository, pointing to a local directory. 6. I clicked on "Add to package..." (argh, still seems like it should be "add package to...") 7. The "AAA" package is not there. Now, I subsequently checked "AAA" in the Package pane and the local dir in the repository pane and pressed "Save". That seemed to work! So I removed the class from the system browser, then went back to the repository, clicked Open, saw the "AAA" category, clicked that and the mcz file name--and it loaded just fine. But I'm worried because step 6 doesn't make any sense to me and doesn't seem to work for me like it does elsewhere. ====Blake===

It is only necessary if you modify a method still in-use; read the comment of the attached method. Further, I would prefer to update the Interpreter to implement primitive 215 using primitive 116, i.e. in the Interpreter's primitive table have both (116 primitiveFlushCacheByMethod) ... (215 primitiveFlushCacheByMethod) "primitiveVoidVMStateForMethod in the CoInterpreter" This is what I've done in the StackInterpreter. In fact, we need to put in time to bring the Interpreter's primitive set into agreement with Cog. So I'm expecting we will have voidCogVMState "Tell the VM to remove all references to any machine code form of the method. This primitive must be called whenever a method is in use and modified. This is more aggressive (and *much* more costly) than flushCache since it must search through all context objects, making sure that none have a (hidden) machine code pc in the receiver. Since modifying a method will likely change the generated machine code, modifying a method (rather than redefining it) requires this more aggressive flush." <primitive: 215> ^self primitiveFailed flushCache "Tell the interpreter to remove all references to this method from its method lookup cache, if it has one.
