hallo folks,
i need to feed the $template parameter of an <$action-createtiddler> widget
with the correct template tiddler's name. The latter has a fixed part
'BASENAME' and a parameterized (or variable) suffix, which is choosen by
means of a <$select> input. The idea is to have a macro build the full name
based on the choice made by using <$select>, like in:
\define templatename() BASENAME-{{!!grammar_class}}
the suffix, as you can imagine, is taken from field grammar_class which is
set by the <$select> widget control.
Now one would expect that things would work nice and easy writing this code:
<$button> create new test tiddler
<$action-createtiddler
$basetitle='testTiddler'
$template=<<templatename>> >
<$action-navigate $to=<<createTiddler-title>>/>
</$action-createtiddler>
</$button>
but disappointingly enough they do not! The new tiddler is created indeed,
but from NO TEMPLATE at all!
Funny as it is, if we add a debug line like:
template's name: <<templatename>> <br/>
it displays correctly as
BASENAME-verb (or BASENAME-noun, or adjective, or whatever the
<$select> choice was)
Hard-coding the name in the macro makes the code work (just for testing
purposes, there is no point here to have a macro just echoing an hard-coded
string).
Now, before I ask why ON EARTH the above code doesn't work, let me say that
I expect for it to be because of how macros are parsed and when macro
substitution is made, in which case I will do a little comment on it later.
Thanks everybody,
CG
