For the life of me, I can't figure out how to make this work - I added
a dispatch in the Perl:
Code:
--------------------
Slim::Control::Request::addDispatch(['sdtMacroString', '_format', '_period'],
[1, 1, 1, \¯oString]);
--------------------
and this is the request from LUA:
Code:
--------------------
{ 'sdtMacroString', text, '0'}
reads *%v and 0*
{ 'sdtMacroString', "format:"..text, 'period:0'}
reads *format:%v and period:0*
or
{ 'sdtMacroString', "_format:"..text, '_period:0'}
reads *_format:%v and _period:0*
or
{ 'sdtMacroString', {'format', text}, 'period:0'}
reads *ARRAY x848918 and period:0*
--------------------
I can't find one example in the acutal SlimServer code where they use
tagged parameters, they're all positional (there's even a note saying
that most users won't ever use the AddParam command, so assume you
don't have to manually parse it on the Perl side.. confused? yes. I'm
OK with positional for the moment, but would love to know the answer.
I've seen examples in the LUA code where they use tagged parameters
using just inline colons. Like here in SlimBrowserApplet.lua,
requestStatus:
Code:
--------------------
{ 'status', from, qty, 'menu:menu', 'useContextMenu:1' }
--------------------
