Remove \\\\ from path variable

[zchris]

I found that the TARGETDIR variable will sometimes contain a double \\ (like c:\\Program Files\\\\MyApp)

I don't want to use

Code: Select all

Set Variable TARGETDIR = $PROGRAMFILES$$TITLE$

because I'm not sure that $PROGRAMFILES$ will always end with \\.

As a workaround I tried

Code: Select all

Set Variable TARGETDIR = $PROGRAMFILES$\\$TITLE$\\X
Extract File Folder: TARGETDIR

however this left me with a \\ at the end (c:\\Program Files\\MyApp\\).

So finally

Code: Select all

Set Variable PROGRAMFILES = $PROGRAMFILES$\\X
Extract File Folder: PROGRAMFILES
Set Variable TARGETDIR = $PROGRAMFILES$$TITLE$

seems to do the trick. Did I overlook something?

Very acute observations Your methods are 100% correct.

Please note that the double slashes are automatically eliminated by all InstallAware scripting functions (including default InstallAware plug-ins).

So an alternate approach would be, if I am guessing correctly, to handle double slashes in your plugins, replacing each instance of \\\\ with \\, and this would make your setup script look cleaner.

Good idea! I'll add that to EditFile.

However it would still be nice to be able to remove the \\\\ from within IA script (I'm using $TARGETDIR$ in a messagebox that informs the user that his old database was renamed).

Could you add either a new command or an option to the Set Variable command?

Thanks.

Good suggestion - a new parameter for Extract File Path maybe?
