The forum

I have been writing a simple script to install RevoUninstaller (it works without any special modification) on the wineprefix of the user's choice, in case it might be useful to uninstall a non-.msi program within a Wineprefix (and not have to delete the virtual drive). However, the problem I have run into is with selecting the Wineprefix is that my script uses AVAILABLE_PREFIXES=$(ls $POL_USER_ROOT/wineprefix), which when fed into POL_SetupWindow_menu with a space as the division between entries, for some reason results in all the prefixes except for the option to create a new prefix appearing on the same line. I've used the same variable declaration in the terminal, then used echo "$AVAILABLE_PREFIXES">>test.txt to make sure that there are spaces between the results from ls, which there are. Is there a PlayOnLinux function that will list prefixes, or maybe some way of separating the results with a pipe or tilde that I am overlooking? Thanks in advance for your help.

 

Here's the script:

Hi,

Results from ls are separated by newlines, not spaces.

echo -n "$AVAILABLE_PREFIXES" |od -c

You could use

AVAILABLE_PREFIXES=$(cd "$POL_USER_ROOT/wineprefix" && echo *)

that would work as long as PlayOnLinux doesn't change its implementation.

There's also POL_SetupWindow_prefix_selector [message], that will return the selected prefix name into $APP_ANSWER, but it will just allow to select from existing prefixes, not tweak the list like you did...

Okay, thanks. I just decided to use POL_SetupWindow_prefix_selector because there isn't much reason to install an uninstaller on an empty Wineprefix. Unfortunately, I've run into another problem: When I close RevoUninstaller, I get an error message from POL Debugger. I've used POL_Shortcut_QuietDebug, but this only seems to fix the problem when I use it from the POL Console.

Here's the revised version of the script:

Well, it seems to genuinely crash at times; POL_Shortcut_QuietDebug is just a bandaid for programs not returning meaningful exitcodes...
