[pmwiki-users] File names with spaces in variables

[Dominique Faure]

In fact, a name-spaced image attachment doesn't render as such when
the name comes from a variable because those are evaluated in the
context of the current page which is the only one available in PmWiki.
So, when the Attach:... markup is handled, the variable content has
already been processed into the page content and the inserted spaces
are seen as an "end of markup" separation.

When dealing with the following page content:

  ptv: aaa bbb.txt
  ...
  Attach:{$:ptv}

The markup rules apply one after the other on it, transforming the page to:

  ptv: aaa bbb.txt
  ...
  Attach:aaa bbb.txt

Which results to:

  ptv: aaa bbb.txt
  ...
  <Resulting HTML of handling of Attach:aaa> bbb.txt

The solution here would be to provide a protected/encapsulated
variable content such as:

  Attach:[=aaa bbb.txt=]

But since the regular PmWiki's content protection markup is acting
before the variable evaluation while rendering the page, the
encapsulation should occur earlier, therefore:

  ptv: [=aaa bbb.txt=]
  ...
  Attach:{$:ptv}

Should do the trick.
