Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
If TESTFN is non-nil, then it is the predicate to lookup
the alist. Otherwise, use 'eq' (Bug#27584).
* lisp/subr.el (alist-get): Add optional arg FULL.
* lisp/emacs-lisp/map.el (map-elt, map-put): Add optional arg TESTFN.
* lisp/emacs-lisp/gv.el (alist-get): Update expander.
* doc/lispref/lists.texi (Association Lists): Update manual.
* etc/NEWS: Announce the changes.
* test/lisp/emacs-lisp/map-tests.el (test-map-put-testfn-alist)
(test-map-elt-testfn): New tests.
The docstring referenced a non-existant parameter, as well as a
parameter that has been renamed since the docstring was written. Fix
both errors, fixing (Bug#24182).
* lisp/emacs-lisp/map.el (map-merge): Use `map-into' for the first map,
and don't use of an intermediate alist.
(map-merge-with): Same, plus use `cl-callf' to try and avoid performing
3 lookups per inner iteration.
* lisp/emacs-lisp/map.el (map-put): Do not bind the evaluated place
expression to a new symbol.
* test/lisp/emacs-lisp/map-tests.el: Add a regression test.
* lisp/emacs-lisp/seq.el (seqp): New name.
* lisp/emacs-lisp/map.el (mapp): New name.
* doc/lispref/sequences.texi: Update the documentation for seqp.
* test/automated/map-tests.el: Update the tests for mapp.
Update map-some to return the returned by the predicate, similar to
seq-some.
* lisp/emacs-lisp/map.el (map-some): Update the function to return the
return value of the predicate.
* test/automated/map-tests.el (test-map-some): Update the test to check
for non-nil values only.
Remove the "-p" suffix from both function names.
* lisp/emacs-lisp/map.el (map-contains-key, map-some): Rename the functions.
* test/automated/map-tests.el (test-map-contains-key, test-map-some):
Update both test functions.
* lisp/emacs-lisp/map.el (map-elt, map-delete): Declare a gv-expander.
* lisp/emacs-lisp/map.el (map-put): Refactor using `setf' and `map-elt'.
* test/automated/map-tests.el: Update tests to work with the new
implementations of map-elt and map-put.
* lisp/emacs-lisp/map.el (map-elt): Define a gv-expander.
* lisp/emacs-lisp/map.el (map--dispatch): Tighten the code.
* lisp/emacs-lisp/map.el (map-put): Redefine it as a function using a
`setf' with `map-elt'.
* test/automated/map-tests.el: Comment out `test-map-put-literal'.
* lisp/emacs-lisp/map.el (map-let): New macro.
(map--make-pcase-bindings, map--make-pcase-patterns): New functions.
* test/automated/map-tests.el: New test for `map-let'.
Since a map is not a data structure but a concept, adding information
about the possible types of maps can be useful information.
* lisp/emacs-lisp/map.el: Add documentation about the type of MAP to
each public function.
* lisp/emacs-lisp/map.el (map-elt): If map is an alist and key is
found but its associated value is nil, do not return the default
value.
* test/automated/map-tests.el: Add a regression test.
* lisp/emacs-lisp/map.el (map-delete): When map is an array, check if
the key is present to avoid signaling an error.
* test/automated/map-tests.el: Add a test for deleting non-existing
keys from maps.
* lisp/emacs-lisp/map.el (map-elt): Do not use `ignore-errors' when
doing a lookup in arrays, but check the boundaries of the array
instead.
* test/automated/map-tests.el: Adds a test for `map-elt' with arrays
and a negative integer as key.
