Thanks.  Maybe I am missing something, “guix show public-inbox” tells
version 1.6.1 but I do not find ’lei’.  Anyway.

That’s why I used this ugly loop. ;-)

Yes, I agree ’lei’ is cool.  For instance, it allows to filter (and thus
follow), e.g., let query for the patches submitted the last 3 months to
’gnu/packages/bioinformatics.scm’ touching R packages,

dfn:gnu/packages/bioinformatics AND b:r-build-system AND rt:3.months.ago..

where

   dfn:     match filename from diff
   b:       match within message body, including text attachments
   rt:      match date-time range, git "approxidate" formats supported
            Open-ended ranges such as `d:last.week..' and `d:..2.days.ago'
            are supported

<https://yhetil.org/guix/?q=dfn%3Agnu%2Fpackages%2Fbioinformatics+AND+b%3Ar-build-system+AND+rt%3A3.months.ago..>

Then, ’lei up’ will request the public-inbox server for this query and
will download the messages if any.
