Trunk Notes Discussion
I always wanted to have an easy way to count the number of items returned by a Trunk Notes list function, especially {{tagged}} and {{action}}. It turned out to be easier to accomplish in lua than I expected. Note that the script below uses the wiki.exprl function, with an 'L', not a '1'.
Count.lua:
fn_name = args[1]
fn_args = args[2]
my_list = wiki.exprl(fn_name, fn_args)
count = #my_list
return count
So, to find out how many pages are tagged with ".Project", I use:
{{lua Count.lua, tagged, .Project}}
Script returns: 82 (Yikes)
One limitation: the tagged function accepts more than one tag and will return a list of those pages with tag1 AND tag2 AND ... tagn. This script only works with one tag.
With some finagling, I can make it work with up to two tags:
fn_name = args[1]
fn_arg1 = args[2]
fn_arg2 = args[3]
my_list = wiki.exprl(fn_name, fn_arg1, fn_arg2)
count = #my_list
return count
This works properly with the above invocation and with the following:
{{lua Count.lua, tagged, .Project, .ThisWeek}}
and returns 14. (That's a little better.) I don't think I'll need more than two
arguments here, but you can see how to extend it if needed.
Trunk Notes Help
Paulo,
Did you ever get any Lua help? I am trying to find anything I can these days. Any help or suggestions would be greatly appreciated.
Thank you.
