Question

I want to allow users to view files in our source control system via links from the Twiki design docs. For now, I'm happy with just viewing the local copies that every developer should have.

So if I type:

file://c:\sourcetree\ProjectX\src\main.c

I get a link to the local file, and my browser displays it just fine, like any other //file link. But everyone has their local source image in a different place. So I created a variable

• • Set file://c:\sourcetree\projectX = file://c:\sourcetree\projectX

Now, I can add the following to a page:

file://c:\sourcetree\projectX\src\main.c

My problem is that on the preview page, this expands correctly to a link, displaying exactly like the link in my first example. But when I save changes, it does not expand the variable, it shows up unexpanded, as

%SOURCETREE%\src\main.c

Why is it different in the preview and the normal view?

Why closedUnanswered? Twiki is a fantastic tool, you guys have done a great job. I think I have a valid question..

If I set the following variable on my home page:

      * Set %SOURCETREE% = file://c:\sourcetree\projectX

Then why does

   %SOURCETREE%\src\main.c

show up as

   file://c:\sourcetree\projectX\src\main.c

in preview, but

   %SOURCETREE%\src\main.c

after saving?

Answer

Nothing personal here. If nobody answered a question after a few month time the likelyhood of getting an answer gets smaller and smaller. Those questions get marked as unanswered so that the list in the Support home does not grow longer and longer.

In your case it looks like you use an unsupported case. To define a variable write:

• Set SOURCETREE = file://c:\sourcetree\projectX

file://c:\sourcetree\projectX

Notice that per topic variables only work in recent TWikiAlphaReleases (as is the case here on TWiki.org)

Preview expands variables twice, this is a bug that has been fixed just now, Codev.PreviewExpandsVariablesTwice.
