Programmatically changing settings values

by Pablo Herrero

Hey everyone, I would like to change some of the environment settings by code, specifically I would like to change the default compiler, from the menu you would do: World Menu >> System >> Settings >> Compiler >> Default Compiler , and then set you preference there. How can you do that programmatically? Thanks in advance!, Pablo

Casting a string as an instance variable.

by sergio_101

I would like to do something like: MyObject updateWIth: aDictionary. then, inside the object, treat the keys as instance variables, and the values as values.. and do something like: (key1 asInstanceVariable(??)): value1. this seems like it should be possible, but i am just not getting it. any ideas? thanks!

Another thing we can doâ¦ we could remove the warning in the method #isInlineAndOr. Then the and: would be compiled as a message as in the non-block example. Marcus

issue with and/or inlining

by Evan Donahue

Hello, I'm currently working on an embedding of the miniKanren logic programming language in Pharo (http://minikanren.org/) and I have run into an issue with the method compilation internals I was hoping someone could shed some light on: miniKanren has an operator, fresh, that basically evaluates a block and returns a logic variable. My current syntax for a conjunction of logic variables is: var1 and: var2 When I try to use the same syntax for fresh: var1 and: [ :var2 | var2 ] Compilation fails with "Warning: and: (or:) takes zero-arg block" which seems on first glance to come from the compiler attempting to inline my and: call. If I add an auxiliary method andFresh: that evaluates the block and and:'s the result in 2 steps, my tests pass. What I'd like to know is: 1) Is there a work around to let me use the and: syntax here? 2) Might my overriding of and: and or: for normal logic variables cause other problems I'm not thinking of? Obviously this is not a critical issue, but my code's aesthetics are at stake, and if we can't have pretty code, then what can we have? Thanks, Evan

Updating Pharo

by nacho

Helo friends, When I update Pharo (World --> System --> Software Update) I see some progressbars that I don't undersand. what is exactly snapshoting? Also, suppose I add Bloc's Monticello repository, does a Software Update also update Bloc when an update is released? Thanks in advance Nacho ----- Nacho Smalltalker apprentice.

Re: [Pharo-users] [ANN] OS Project with initial support for Ubuntu and Unix

by Damien Cassou

that is really great news, thank you very much. Do you plan a common interface to manipulate OSes polymorphically? This could include: - opening an external application - sending a file to the trash - ... Thanks again!

Re: [Pharo-users] Extending GTSpotter

by Damien Pollet

Both GTSpotter>>spotterImplementorsFor: and GTSpotterCandidatesProcessor>>is:matching: do substring matching, so I'm wondering if the matching logic is duplicated/distributed in several places.
