The existing behaviour for seq-subseq is to error when indexes are too
large, but to silently ignore numbers which are too negative for lists.
String and vector handling errors in both cases. This has been
regularlised.
Error signalling behaviour has been explicitly added to the docstring of
seq-subseq, and also to cl-subseq which largely defers to
seq-subseq (and is therefore also impacted by this change).
Tests have been added for these exceptional cases, as well as one non
exceptional base case.
* src/lisp.mk (lisp): Add emacs-lisp/cl-generic.elc.
* lisp/emacs-lisp/cl-generic.el (cl-generic-define-method):
Avoid defalias for closures which are not immutable.
(cl--generic-prefill-dispatchers): New macro. Use it to prefill the
dispatchers table with various entries.
* lisp/emacs-lisp/ert.el (emacs-lisp-mode-hook):
* lisp/emacs-lisp/seq.el (emacs-lisp-mode-hook): Use add-hook.
* lisp/emacs-lisp/seq.el: The pcase pattern now matches only if the
object is a sequence, and binds each element of ARGS to the
corresponding element of the sequence.
* lisp/emacs-lisp/seq.el (seq--make-bindings): Add support for `&rest'
in the argument list.
* test/automated/seq-tests.el: Add a test for parsing and binding
`&rest' in `seq-let'.
* lisp/emacs-lisp/seq.el (seq-let): New macro. `seq-let' is similar
to `cl-destructuring-bind' but works on all sequence types supported
by `seq.el'. Bump version number to 1.6.
* test/automated/seq-tests.el: Add tests for seq-let.
* doc/lispref/sequences.texi: Add documentation for seq-let.
(seq-doseq): Fix out-of-scope binding.
Don't call `seq-length at every iteration.
Reduce `if's from 3 to 2 per iteration.
(emacs-lisp-mode-hook): Don't tweak in Emacs≥25.
* lisp/emacs-lisp/seq.el (seq-intersection, seq-difference): New
functions.
* test/automated/seq-tests.el: Add tests for seq-intersection and
seq-difference.
* doc/lispref/sequences.texi: Add documentation for seq-intersection
and seq-difference.
* lisp/emacs-lisp/seq.el: Make seq-into a public function (replacing
seq--into)
* test/automated/seq-tests.el: Add tests for seq-into
* doc/lispref/sequences.texi: Add documentation for seq-into
* lisp/emacs-lisp/seq.el (seq-reverse): Add a backward-compatible
version of seq-reverse that works on sequences in Emacs 24. Bump
version to 1.2.
* test/automated/seq-tests.el (test-seq-reverse, test-seq-group-by):
Add a test for seq-reverse and update test for seq-group-by to test
vectors and strings, not only lists.
* lisp/emacs-lisp/seq.el (seq-group-by): Improves seq-group-by to
return sequence elements in correct order
* tests/automated/seq-tests.el: Update test for seq-group-by
* doc/lispref/sequences.texi (Sequence Functions): Update documentation
examples for seq-group-by
