[Users] nesting conditions in matcherrc

[Adrian]

Thank you wwp

Yes I understand about the test for Fred. I was using 'shorthand'.

I'd happily use the UI if it wasn't so much harder than hacking the
text.  I get it wrong more often with the UI than with editing.  I know
it's syntactically correct, but syntactically-correct-and-does-nothing
is no help!

It can't. Mixing & and |, () and de facto operator precedence are not
implemented.

Your question is not clear to me. Moreover, "is" is not accurate
enough. Does it mean "contains" or "is equal to"?
If you need to determine if the From header contains or is Fred,
semantically it could appear to be the same, but in the domain of
filtering expressions, it's definitely different.

What you might only need is one condition:
from matchcase "Fred"
but it may match much more than what you expect.

Editing by hand the matcherrc file is not what I'd call a good idea,
unless you really know what you're doing and well know how filtering
works and filtering expressions in Claws Mail. Getting to the UI is
what I'd recommend ;-).
