Re: Mac Standalone Bug
True, in 4.0 I disabled destroyStack but it still happens. The work around was to write a resizing routine on preOpenStack for all objects to get the to fit correctly within the stack. This slows down the spped at which the stack opens on initial launch but is otherwise unnoticed. - Justin ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: Line Numbers in Text Editor
Richard, Fantastic primer on handling line numbers in Rev! Thank you! It's amazing how something seemingly so simple can have such a huge impact.

Re: Line Numbers in Text Editor
I went with using a parallel field to add line numbers and it is working well. However, rev only counts the line numbers based on the delimeter. So if word warp is turned on you end up with more lines then there are actual line numbers. Does anyone know of a way to count all the lines, even the lines that are wrapped and not separated by the delimeter? - Justin On Thu, Jun 24, 2010 at 5:44 PM, Jeff Massung wrote: > I used a parallel field in my Cryogen editor (http://massj.tumblr.com for > video + screenshot).

Re: Shell Command with Sudo
Peter, That is a good suggestion if the application was not meant for mass deployment. Otherwise each machine's sudoers file would have to be edited accordingly, which would be a bummer for users that do not know how to do so. And that is likely the majority of Mac users. I would venture to say that the majority of Mac users never even opened the Terminal. The solution is elegant, I believe, in that it will work on any Mac OS X machine and takes advantage of Bash' s flexibility with Rev's shell structure.

Re: Shell Command with Sudo
Thanks to all who replied. With you help and some additional research
I came up with a solution.
Mac OS X bash shell only allows results from commands to be piped in
to another command, including sudo, not plain text. The solution is to
set a bash variable (pw=password) and echo the variable to pipe it
into sudo (echo $pw | sudo -S command). In Rev you must set the
variable and pipe it in on the same shell() call. Like this:
shell("pw=" & tPassword & "; echo $pw | sudo -S command")
Works like a charm, and it's an elegant solution without a lot of
hashed code. I have not tested this on other Unix based systems but
the command should work on any system with bash as the default shell.
Happy coding!

Shell Command with Sudo
Hello All, I am trying to run a shell() command in revStudio in order to execute some terminal commands as the superuser on a Mac. An Ubuntu terminal will accept the superuser password using a pipe, such as "pass | sudo -S command", but Mac's terminal will not accept the password on the same line. Is there a way to run multiple commands from a single rev shell() call? Or, can I somehow followup a shell() call with the password?

Re: revStudio for Linux Also $50
No, I purchased the Mac version. I noticed the option when I went to activate my code and RunRev and get my serial for Studio. After you enter your activation code provided by TheMacSale you are presented with a form to fill in your name and address. At the botton of the form you select your OS. It sounds to me like you can select whatever version you want. On Thu, Jun 10, 2010 at 3:58 PM, David C. wrote: >> TheMacSale.com bundle is ending on 15 June.

You then take that activation code to the RunRev website and choose which OS you are planning to run it on.
