* lisp/progmodes/cperl-mode.el (cperl-info-on-current-command):
Use cperl-perldoc instead of cperl-info-on-command.
(cperl-imenu-on-info): Shortcut this function since the Perl info
file can no longer be installed.
* lisp/progmodes/cperl-mode.el (cperl-invalid-face): Make
obsolete in favor of 'show-trailing-whitespace'.
(cperl-init-faces): No longer highlight trailing whitespace
separately.
(cperl-praise, cperl-tips-faces): Update documentation for above
change.
The Perl documentation in info format is no longer distributed with Perl,
nor is it available from CPAN. Point to cperl-perldoc instead.
* lisp/progmodes/cperl-mode.el (cperl-info-page): Make obsolete.
(cperl-tips): Remove outdated instructions to get Perl info
sources from the docstring.
(cperl-praise): Remove advertising the info interface in the
docstring.
(cperl-mode-map): Replace bindings to `cperl-info-on-command' and
`cperl-info-on-current-command' by `cperl-perldoc'.

(cperl-mode): Remove explanation of the Perl info commands from
the docstring.
(cperl-info-on-command, cperl-info-on-current-command),
(cperl-imenu-info-imenu-search, cperl-imenu-on-info): Declare the
commands obsolete.
* etc/NEWS: Describe the obsoletion of Perl info commands.
mode-compile.el is no longer available from any maintained repository,
its archived version does not work since Emacs 27. The menu options
tested for availability of mode-compile and therefore were disabled,
the function was not documented.
* lisp/progmodes/cperl-mode.el (cperl-tips): Remove reference to
mode-compile.el.
(cperl-menu): Remove defunct entries requiring mode-compile.
(cperl-check-syntax): Remove function.
(cperl-extra-perl-args): Remove user option only used by cperl-check-syntax.
* lisp/progmodes/cperl-mode.el (cperl-sniff-for-indent): Recognize
the end of a format declaration as a statement boundary. This fixes
indentation if several format declarations immediately follow each
other.
(cperl-find-pods-heres): use the correct capture group for the
name of an unterminated format declaration. Fix an out of
boundary error when a format declaration is typed at the end of a
buffer (Bug#66139).

unquoted delimiters for here-documents are now forbidden
(Bug#65834).

resource with source code from the bug report.
* lisp/progmodes/cperl-mode.el (cperl-fontify-trailer): New
customization variable. With a value of 'comment, cperl-mode
treats trailing text after after __END__ and __DATA__ as comment,
like perl-mode does (Bug#66161).
(cperl-find-pods-heres): Treat trailing text after __END__ and
__DATA__ according to the customization variable
`cperl-fontify-trailer'.

New test, verifying the changed behavior if the custom variable is
set to 'comment.
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-66161.pl: New
resource file, source code from the corresponding bug report.

matchers for fontification of array and hash elements and keys so
that they don't override comment and string fontification (Bug#66145).
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-66145):
New test for all combinations of sigils and brackets/braces to
verify that strings and comments are left untouched. This test
also works for perl-mode which has always done it correctly.
* test/lisp/progmodes/cperl-mode-resources/cperl-bug-66145.pl: New
resource file for the above test.
Subroutine names are fontified as subroutine names even if the name is also
the name of a builtin (fixing an ancient unreported bug). Subroutine name
are just comments in comment and pod (fixing a bug introduced recently)
* lisp/progmodes/cperl-mode.el (cperl-init-faces): Move
fontification of sub declarations before that of builtins. Don't
override existing faces when fontifying subroutine declarations.
Don't fontify method calls even if the sub names match those of
builtins.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-fontify-sub-names):
New tests with a subroutine name in several surroundings.
* test/lisp/progmodes/cperl-mode-resources/sub-names.pl: New resource
for the new test.
* lisp/progmodes/cperl-mode.el (imenu-max-items): declare the
variable to silence an elint warning.
(cperl-short-docs): Reorder function description to match Perl's
perlfunc documentation. Add missing shortdocs from perlfunc.
Delete entries for operators which don't exist any more (EQ, NE
and friends). Shorten docstring lines to 80 chars or less.
Attributes may start with underscore, and must be separated.
Thanks to Mattias Engdegård for pointing out a regex mistake.
* lisp/progmodes/cperl-mode.el (defconst): Fix bad grouping and
allow attributes to start with an underscore in
cperl--single-attribute-rx. Adjust cperl--attribute-list-rx
accordingly.
(cperl-find-sub-attrs): Allow attributes to start with an underscore.

(cperl-test-attribute-list-rx): Add new test cases for valid and
invalid attribute lists.

assertion to cperl--single-attribute-rx
(cperl-after-sub-regexp): Dito
(cperl-init-faces): shorten matches of incomplete sub declarations

(defconst): Fix typo in docstring of cperl--single-attribute-rx.
