I think this is from the 80's or 90's where this could save some memory. According to my calculations in Squeak 4.2 with some extra packages loaded it saves at least 36591 bytes (object size + 1 slot in the literal array), which is only 0.79 bytes / method.

Re: [Pharo-project] Sound

Sound package were moved in an external package. The package was broken, I try to fix it but I did not test it, as far as I remember.

Hi Eliot, I noticed that some tests fail (with errors) when run under coverage with COG, while they succeed otherwise. In regular VM, no error whether coverage test or regular tests...

Non-literal strings should do what you want. I wonder how useful the optimization is, actually. Probably not many (if any) methods will use the same literal multiple times and count on the compiler to optimize them into the same literal.

[Pharo-project] Updated Metacello Configurations of OmniBrowser, RefactoringBrowser, OCompletion

by Mariano Martinez Peck

Hi. I just wanted to let you know that I have updated those configurations to work in Pharo 1.1 with their latest versions. All tests are green ConfigurationOfOmniBrowser -> 1.2 ConfigurationOfRefactoringBrowser -> 1.6 ConfigurationOfOCompletion -> 1.2 Now the problem is that I don't know why OCompletion is not working with OB, even when all tests are green :( If someone can help please. Cheers Mariano

>From Pharo By Example: Symbols are like Strings, in that they contain a sequence of characters. However, unlike a string, a literal symbol is guaranteed to be globally unique. There is only one Symbol object #Hello but there *may be* multiple String objects with the value 'Hello'. According to the above: Strings -> 1+ per value Symbols -> always one per value Where did you get that Strings are guaranteed not to be 1 per value?

The basic browsers work fine http://localhost:8080/glamour/basicExamples But in the developer Examples some do not work, e.g. http://localhost:8080/glamour/devExamples Class listing - only an empty browser shows up.
