Dynamic block match fails on checkbox columns

Dynamic block match fails on checkbox columns

I'm trying to use a dynamic block with :match to filter columnview for a
checkbox column.  However, the match is failing.   Based on some variations
that do work (described below the example), it seems the closing square
bracket may be the problem.

Here's a minimal example:
* Things
  :PROPERTIES:
  :COLUMNS:  %20ITEM %CHKBOX{X/}
  :ID:       Things
  :CHKBOX_ALL: "[ ]" "[X]"
  :END:
*** One Thing
    :PROPERTIES:
    :CHKBOX:   [X]
    :END:
*** Another Thing
    :PROPERTIES:
    :CHKBOX:   [ ]
    :END:

* Dynamic Block
  #+BEGIN: columnview :id Things :match "CHKBOX=\"[X]\""
  | ITEM | CHKBOX |
  |------+--------|
  #+END:

If I use curly braces for CHKBOX_ALL (i.e., "{ }" "{X}") instead of square
braces, it works fine (of course, I have to also use :match
"CHKBOX=\"{X}\"").  But then the SUMMARY-TYPE in the COLUMNS definition
doesn't work.  The match (but not the summary) also works if I remove just
the *closing *square bracket from the CHKBOX properties and the :match
string.  FWIW, the match also fails for the case of searching for unchecked
items (i.e., :match "CHKBOX=\"[ ]\"").

Thanks for reporting!
It is kind of expected from the manual explanation about tag matchers:

   • If the comparison value is enclosed in double-quotes _and_ angular
     brackets (like ‘DEADLINE<​="<2008-12-24 18:30>"’), both values are
     assumed to be date/time specifications in the standard Org way...

However, the heuristics described in the manual is obvious wrong here.

I improved the match parser a bit to require a number inside brackets in
timestamps, but this whole syntax is overcomplicated and difficult to
understand.

In any case, your bug should be fixed now on main.
