* lisp/emacs-lisp/seq.el (seq-position): New function.
* test/automated/seq-tests.el: New tests for seq-position.
* doc/lispref/sequences.texi: Add documentation for `seq-position'.
* doc/lispref/sequences.texi:
* lisp/emacs-lisp/seq.el: Update the documentation of seq-some to
guarantee that the returned value is the first non-nil value that
resulted from applying the predicate.
* lisp/emacs-lisp/seq.el (seq-find): Improve the docstring and rename
the parameter `sentinel' to `default'.
* doc/lispref/sequences.texi (Sequence Functions): Update the
documentation for `seq-find' accordingly.
This function is similar to `seq-some' but returns the found element.
In the cases where nil can be the found element, a sentinel optional
argument can be provided to avoid ambiguities.
* lisp/emacs-lisp/seq.el (seq-find): New function.
* test/automated/seq-tests.el (test-seq-find): Add tests for `seq-find'.
* doc/lispref/sequences.texi (Sequence Functions): Add documentation for
seq-find.
Update seq-some to return non-nil if the predicate returns non-nil for
any element of the seq, in which case the returned value is the one
returned by the predicate.
* lisp/emacs-lisp/seq.el (seq-some): Update the function and its
docstring.
* test/automated/seq-tests.el (test-seq-some): Add a regression test.
* doc/lispref/sequences.texi (Sequence Functions): Update the
documentation for seq-some.
* lisp/emacs-lisp/seq.el (seq-some, seq-contains): Rename the functions
without the "-p" prefix.
* test/automated/seq-tests.el (test-seq-some, test-seq-contains): Update
the tests accordingly.
* doc/lispref/sequences.texi (Sequence Functions): Update the
documentation for seq.el.
Use the new `seq-into-sequence' in seqs passed to `seq-concatenate' to
ensure that concatenation happens on sequences only. This makes it
possible to use `seq-concatenate' for new types of seqs.
* lisp/emacs-lisp/seq.el (seq-into-sequence, seq-concatenate): New
function used in `seq-concatenate'.
* test/automated/seq-tests.el (test-seq-into-sequence): New unit test
for seq-into-sequence.
* lisp/emacs-lisp/cl-extra.el (cl-subseq, cl-concatenate): Do not use
seq functions.
* lisp/emacs-lisp/seq.el (seq-concatenate): Call cl-concatenate in
seq-concatenate.
Since most new types of seq would have to be defined as sequences (cons
cells or CL structs, mostly), there is no need to convert the seqs to
sequences (which can be a fairly expensive operation).
* lisp/emacs-lisp/seq.el (seq-concatenate): Do not ensure that seqs are
sequences.
* lisp/emacs-lisp/seq.el: Define seq.el functions using cl-defmethod to
make it easier to extend seq.el with new "seq types".
* test/automated/seq-tests.el (test-setf-seq-elt): New test.
* lisp/emacs-lisp/cl-extra.el (cl-subseq): Move back the definition of
subseq in cl-extra.el, and use it in seq.el.
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
