"failed to parse" with percent sign

[Xu Wang]

Dear list,

I have a message id with a % in it. When I run the following (the
message ID is not complete here to keep some anonymity)

mutt -e "set nm_query_type=threads" -f 'notmuch://?query=id:Z23B3X20.22Ba8%'

I receive:

failed to parse notmuch uri: notmuch://?query=id:Z23B3X20.22Ba8%

Using backslashes to escape the percentage sign does not seem to work.

As a side note, shouldn't there be a non-zero exit code if fail to parse?

Kind regards,

Xu

It's URL, so you have to use proper encoding, see
 https://en.wikipedia.org/wiki/Percent-encoding

Note that % has special meaning (it's prefix for %<hex>), I guess you
 need %25 rather than %:

mutt -e "set nm_query_type=threads" -f 'notmuch://?query=id:Z23B3X20.22Ba8%25'

Hmm... seems like a bug.

Thank you very much for your explanatory response, Karel.

I am confused though as to why '@' does not need to be
percent-encoding? Only percents need to be?

Kind regards,
