Subject: bug#58278: Add new function seq-keep
Date: Mon, 03 Oct 2022 23:30:13 +0200 [thread overview]
Message-ID: <87y1twtx22.fsf@bernoul.li> (raw)
While I still appreciate the `dash' package, I try to avoid it in
a package when all or most of its used `dash' functions and macros,
can be replaced with equivalent functions/macros from `seq', `cl-lib'
or other parts of Emacs.
Unfortunately I cannot find a replacement for `-keep', which I have been
using a lot. I propose that we add something like:
(cl-defgeneric seq-keep (pred sequence)
"Return a list of all non-nil results of (PRED element) for elements in SEQUENCE."
(delq nil (seq-map (lambda (elt) (funcall pred elt))
sequence)))
Cheers,
Jonas
