Perhaps a different approach could be to use just a placeholder in
master_sites:
master_sites ${homepage}attachment/wiki/WikiStart/<file>?
format=raw&dummy=
or something to that effect (since <> are not valid in HTTP URLs).
When no
<file> is present, append to the end like we do now.
Placeholder sounds very good. I might prefer a sprintf placeholder,
like
%s (% isn't valid by itself in a URL either).
% is valid for escaping; I wanted to pick something that wouldn't
otherwise
appear in any URL so the template-replacing code would be simpler.
But %s by itself is not valid in URLs, and %s is the standard string
replacement placeholder for the printf function. Um, which in tcl
is the
format function. So the replacement code is simple:
[format ${url} ${distfile}]
Or something like that.
% format "http://distfiles.macports.org/stuff/%s"; "test-1.2.3.tar.gz"
http://distfiles.macports.org/stuff/test-1.2.3.tar.gz
Okay, makes sense, but
% format "http://distfiles.macports.org/stuff%20here/%s";
"test-1.2.3.tar.gz"
expected floating-point number but got "test-1.2.3.tar.gz"
So if there's any % escaping, format may not be the best choice...
Good catch. "%20h" is valid printf formatting for 20 characters of
hexadecimal digits... not what we want. So scratch that idea.
granted some work would have to go into using a different style as
well,
so it's hard to say which is the better way to go.
Let's go with your <file> idea instead.
