[racket-users] inadvertently upgraded Racket version. Would like to make an older installed version current.
I inadvertently upgraded Racket version. Would like to make an older installed version current. So now when I start DrRacket v8 is current. Is there a command that makes a specified version current? Does raco pkg remove effectively make the previous version current? Thanks. Don. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Regarding collections and racket versions...
All of my programming code is in a single collection: ~/.plt-scheme/4.2.1/collects/ even when I have installed newer versions of Racket. The 'raco setup' function updated all my program bytecodes throughout my system. I do go through some confusion regarding collections when I install a newer version of racket because I believe it makes use of a newer default collection and if I remember correctly, I make a change somewhere so that the system looks to my original collection location instead. I appreciate any comments or advice regarding collections in general, or my use of the single collection directory: ~/.plt-scheme/4.2.1/collects/ :) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Is there a function to find and update all compiled directories?
Thanks for all the wonderful feedback! The 'raco setup' function worked beautifully for me resolving my issues. Running raco setup without arguments did bring my system to it's knees, i.e., slowing it down to a snail's pace but after a reboot all seems to be well. Based on the displayed feedback, I saw that it did a lot of work. Would there be less work for 'raco setup' if I uninstalled all but the current and previous versions of Racket?

[racket-users] Is there a function to find and update all compiled directories?
I've never had problems with the .zo files being auto-created during development, only when update the Racket version because of course then a new compiler is involved. If I am remembering correctly, any time I've had issues with the compiled files, I've resolved them by deleting the compiled directory identified by the error message. Which only makes me wonder if there is some function I am unaware of that will update compiled directories without needing to specify the path to each one, or find and delete them all (Racket recreates them). -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Which action should I take: (a) go back to using Racket v.7.7 or (b) resolve issues.
I'm nervous. After installing racket version 7.8 on linux (Ubuntu) at a time when I really should not have done only because I'm in the middle of development and would much prefer to change the version at a later date. The installation did not go without a hitch this time, meaning the problem seems to be minor but will take me time to resolve. I am inclined to return to version 7.7, if that is possible. Q. Is it a mistake to simply reinstall racket v.7.7? Does that action make it the current version even though version 7.8 is now installed. Q. To change the current racket version should I be using: a) raco setup... or possibly: b) raco pkg remove and raco pkg install Q. I've been reading up on "Getting Started with Packages" but am I correct in thinking they are conceptually within a racket version rather than the complete definition of a racket version.

How do I avoid the auto-creation of the 'compiled' directory which currently occurs every time I create a module?

[racket-users] My gmail auto receives new top-level entries from [Racket Users] but not reply entries...
Hi, It has been awhile since I've been posting questions to [Racket Users]. Previously, my gmail account would receive both my query entry and every reply entry. (Of course, it actually received all entries and replies entered into [Racket Users].) When I began using [Racket Users] recently, I notice that all top-level entries are being automatically sent to my email address (which is as I like), but no replies are being sent. When I logged onto [Racket Users] today, I notice that I had 4 or 5 replies. Great! Can anyone advise how I might begin to configure somewhere so that I receive all reply entries in addition to the top-level entries that I currently receive in my gmail account?
