TWC filter syntax supports selecting tiddlers by matching field values,
like this:
[fieldname[value]]
However... this filter requires an exact match of the entire value, so it
is not sufficient for your purposes. Unfortuately, MatchTagsPlugin won't
do the job either: although it allows use of boolean logic to select
tiddlers based on combinations of tags, it does not handle filtering based
on other field values, so comparison of tiddler title text is not supported.
One possible workaround strategy would be to add the month name as a tag
value on each log tiddler. Assuming you are using the TWCore
<<newJournal>> macro to create your log tiddlers, you could use a "computed
parameter" to automatically add the current month name, like this:
<<newJournal "YYYY-0MM-0DD" log {{new Date.formatString("MMM")}}>>
Then, with the month name tag on each log tiddler, you can use
MatchTagsPlugin to select by both "log" and a specific month, and output a
popup... like this:
<<matchTags popup "label:May" "prompt:view logs from May" sort:-modified log
and May>>
To make this even easier, create a tiddler (e.g, [[ShowLogsByMonth]]) and
replace the hard-coded month name with $1, as a *substitution marker* for
use with tiddler transclusion via the <<tiddler>> macro:
<<matchTags popup "label:$1" "prompt:view logs from $1" sort:-modified log
and $1>>
To use this, you can simply write:
<<tiddler ShowLogsByMonth with: May>>
