The parser currently only allows simple literals (quoted strings
without interpolation) and identifiers (plain variable names) in
the key (left-hand-side) of hashes and function parameters. v3
also suffers from the same problem.
Here are two different fixes: a workaround and a patch. Take your
pick.
- build the argument hash manually:
[% adashb = 'a-b' %]
[% args = {}; args.arg1 = 'arg2'; args.$adashb => 2; %]
[% USE bar = url ("http://no.where.com";, args) %]
This does replace adashb... [% bar %]
- apply the one-line patch below. This allows $var and ${var}
to also be used as keys in hashes. After you apply the patch
you need to run "yc" in Template-Toolkit-2.04/parser. Then
redo make, make test and make install.
With the patch your example should work without changes.
