streams are cool, you could stream virtually anything!

[Nicolas Petton]

Hi guys,

Aren't you tired of writing the same for loops in various contexts?
I know I was, and there's a better way!

I just added a function `stream-regexp' to stream.el to stream the
search of a regexp in a buffer:


    (let ((str (stream-regexp buf ".*foo\\(.*\\)$")))
      (seq-map (lambda (match-data)
                 ...)
               str))

(I still have to document it and test it properly)

Because streams are lazy and immutable, you can reuse such a stream
forever or keep it for later, move around in a buffer or modify the
buffer and re-evaluate the stream (you'll get new match data), or map
the result, etc.

All the credit goes to Damien Cassou for giving me the idea :-)

Cheers,
Nico
