5.002 beta 1
If you're adventurous, have a look at ftp://ftp.sems.com/pub/outgoing/perl5.0/perl5.002beta1.tar.gz Many thanks to Andy for doing the integration. Obviously, if you consult the bugs database, you'll note there are still plenty of buglets that need fixing, and several enhancements that I've intended to put in still haven't made it in (Hi, Tim and Ilya). But I think it'll be pretty stable. And you can start to fiddle around with prototypes (which are, of course, still totally undocumented). Packrats, don't worry too much about readvertising this widely. Nowadays we're on a T1 here, so our bandwidth is okay. Have the appropriate amount of jollity. Larry

-Since I've received requests to do so, I'm posting the cperl-mode.el
-file. This allows Emacs (both version 18 and 19) to do nice things
-when editing Perl code. Indentation works well, and it doesn't get
-confused like the perl-mode.el that comes with Emacs 19.
-
-Install this file as cperl-mode.el, and add the following to your
-.emacs file:
-
-(autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t)
-
-This cperl-mode.el is not exactly the same as when it was originally
-posted here. I made the following changes: perl-mode is an alias for
-cperl-mode, and the major mode name is perl-mode, not cperl-mode.
-This is so it is easier to use with Emacs 19. I suppose one could
-install this as perl-mode.el and then not have to put the autoload
-line in (for Emacs 19).
-
-Anyway, I'm not maintaining this, so don't send me bugs.

+
+;;; To use this mode put the following into your .emacs file:
+
+;; (autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t)
+
+;;; You can either fine-tune the bells and whistles of this mode or
+;;; bulk enable them by putting
+
+;; (setq cperl-hairy t)
+
+;;; in your .emacs file. (Emacs rulers do not consider it politically
+;;; correct to make whistles enabled by default.)
+
+;;; Additional useful commands to put into your .emacs file:
+
+;; (setq auto-mode-alist
+;; (append '(("\\.[pP][Llm]$" . perl-mode)) auto-mode-alist ))
+;; (setq interpreter-mode-alist (append interpreter-mode-alist
+;; '(("miniperl" . perl-mode))))
+
+;;; The mode information (on C-h m) provides customization help.
+;;; If you use font-lock feature of this mode, it is advisable to use
+;;; eather lazy-lock-mode or fast-lock-mode (available on ELisp
+;;; archive in files lazy-lock.el and fast-lock.el). I prefer lazy-lock.
+
+;;; Faces used now: three faces for first-class and second-class keywords
+;;; and control flow words, one for each: comments, string, labels,
+;;; functions definitions and packages, arrays, hashes, and variable
+;;; definitions. If you do not see all these faces, your font-lock does
+;;; not define them, so you need to define them manually. Maybe you have
+;;; an obsolete font-lock from 19.28 or earlier. Upgrade.
+
+;;; If you have grayscale monitor, and do not have the variable
+;;; font-lock-display-type bound to 'grayscale, insert
+
+;;; (setq font-lock-display-type 'grayscale)
+
+;;; to your .emacs file.
+
+;;;; This mode supports font-lock, imenu and compile-mode. In the
+;;;; hairy version font-lock is on, but you should activate imenu
+;;;; yourself (note that compile-mode is not standard yet). Well, you
+;;;; can use imenu from keyboard anyway (M-x imenu), but it is better
+;;;; to bind it like that:
+
+;; (define-key global-map [M-S-down-mouse-3] 'imenu)
+
+;;; In fact the version of font-lock that this version supports can be
+;;; much newer than the version you actually have. This means that a
+;;; lot of faces can be set up, but are not visible on your screen
+;;; since the coloring rules for this faces are not defined.
+
+;;; Tips: ========================================
+
+;;; get newest version of this package from
+;;; ftp://ftp.math.ohio-state.edu/pub/users/ilya/lisp
+;;; and/or
+;;; ftp://ftp.math.ohio-state.edu/pub/users/ilya/perl
+
+;;; Get support packages font-lock-extra.el, imenu-go.el from the same place.
+;;; (Look for other files there too... ;-) Get a patch for imenu.el.
+
+;;; Get perl5-info from
+;; http://www.metronet.com:70/9/perlinfo/perl5/manual/perl5-info.tar.gz
+;;; (may be quite obsolete, but still useful).
+
+;;; If you use imenu-go, run imenu on perl5-info buffer (can do it from
+;;; CPerl menu).
+
+;;;; Known problems: ========================================
+
+;;; The very new pod
+;;; features. The rules are:
+
+;;; /\n=/ should start comment mode, and
+;;; /\n=cut\s/ should stop comment mode
+
+;;; Expansion of keywords tries to detect this kind of commenting, but
+;;; a "=" that starts a perl row (as in multiline comment and here
+;;; document) can confuse it.
+
+;;; The main trick (to
+;;; make $ a "backslash") makes constructions like ${aaa} look like
+;;; unbalanced braces. The only trick I can think out is to insert it as
+;;; $ {aaa} (legal in perl5, not in perl4).
+
+;;;; Known non-problems: ========================================
+
+;;; Perl quoting rules are too hard for CPerl. Try to help it: add
+;;; comments with embedded quotes to fix CPerl misunderstandings:
+
+;;; $a='500$'; # ';
+
+;;; You won't need it too often.
+
+;;; Now the indentation code is pretty wise. If you still get wrong
+;;; indentation in situation that you think the code should be able to
+;;; parse, try:
+
+;;; a) Check what Emacs thinks about balance of your parentheses.
+;;; b) Supply the code to me (IZ).
+
+;;; Updates: ========================================
+
+;;; Made less hairy by default: parentheses not electric,
+;;; linefeed not magic. Bug with abbrev-mode corrected.
+
+;;;; After 1.4:
+;;; Better indentation:
+;;; subs inside braces should work now,
+;;; Toplevel braces obey customization.
+;;; indent-for-comment knows about bad cases, cperl-indent-for-comment
+;;; moves cursor to a correct place.
+;;; cperl-indent-exp written from the scratch! Slow... (quadratic!) :-(
+;;; (50 secs on DB::DB (sub of 430 lines), 486/66)
+;;; Minor documentation fixes.
+;;; Imenu understands packages as prefixes (including nested).
+;;; Hairy options can be switched off one-by-one by setting to null.
+;;; Names of functions and variables changed to conform to `cperl-' style.
+
+;;;; After 1.5:
+;;; Some bugs with indentation of labels (and embedded subs) corrected.
+;;; `cperl-indent-region' done (slow :-()).
+;;; `cperl-fill-paragraph' done.
+;;; Better package support for `imenu'.
+;;; Progress indicator for indentation (with `imenu' loaded).
+;;; `Cperl-set' was busted, now setting the individual hairy option
+;;; should be better.
+
+;;;; After 1.6:
+;;; `cperl-set-style' done.
+;;; `cperl-check-syntax' done.
+;;; Menu done.
+;;; New config variables `cperl-close-paren-offset' and `cperl-comment-column'.
+;;; Bugs with `cperl-auto-newline' corrected.
+;;; `cperl-electric-lbrace' can work with `cperl-auto-newline' in situation
+;;; like $hash{.
+
+;;;; 1.7 XEmacs (arius@informatik.uni-erlangen.de):
+;;; - use `next-command-event', if `next-command-events' does not exist
+;;; - use `find-face' as def. of `is-face'
+;;; - corrected def. of `x-color-defined-p'
+;;; - added const defs for font-lock-comment-face,
+;;; font-lock-keyword-face and font-lock-function-name-face
+;;; - added def. of font-lock-variable-name-face
+;;; - added (require 'easymenu) inside an `eval-when-compile'
+;;; - replaced 4-argument `substitute-key-definition' with ordinary
+;;; `define-key's
+;;; - replaced `mark-active' in menu definition by `cperl-use-region-p'.
+;;; Todo (at least):
+;;; - use emacs-vers.el (http://www.cs.utah.edu/~eeide/emacs/emacs-vers.el.gz)
+;;; for portable code?
+;;; - should `cperl-mode' do a
+;;; (if (featurep 'easymenu) (easy-menu-add cperl-menu))
+;;; or should this be left to the user's `cperl-mode-hook'?
+
+;;; Some bugs introduced by the above fix corrected (IZ ;-).
+;;; Some bugs under XEmacs introduced by the correction corrected.
+
+;;; Some more can remain since there are two many different variants.
+;;; Please feedback!
+
+;;; We do not support fontification of arrays and hashes under
+;;; obsolete font-lock any more. Upgrade.
+
+;;;; after 1.8 Minor bug with parentheses.
+;;;; after 1.9 Improvements from Joe Marzot.
+;;;; after 1.10
+;;; Does not need easymenu to compile under XEmacs.
+;;; `vc-insert-headers' should work better.
+;;; Should work with 19.29 and 19.12.
+;;; Small improvements to fontification.
+;;; Expansion of keywords does not depend on C-? being backspace.
+
+;;; after 1.10+
+;;; 19.29 and 19.12 supported.
+;;; `cperl-font-lock-enhanced' deprecated. Use font-lock-extra.el.
+;;; Support for font-lock-extra.el.
+
+;;;; After 1.11:
+;;; Tools submenu.
+;;; Support for perl5-info.
+;;; `imenu-go-find-at-position' in Tools requires imenu-go.el (see hints above)
+;;; Imenu entries do not work with stock imenu.el. Patch sent to maintainers.
+;;; Fontifies `require a if b;', __DATA__.
+;;; Arglist for auto-fill-mode was incorrect.
+
+;;;; After 1.12:
+;;; `cperl-lineup-step' and `cperl-lineup' added: lineup constructions
+;;; vertically.
+;;; `cperl-do-auto-fill' updated for 19.29 style.
+;;; `cperl-info-on-command' now has a default.
+;;; Workaround for broken C-h on XEmacs.
+;;; VC strings escaped.
+;;; C-h f now may prompt for function name instead of going on,
+;;; controlled by `cperl-info-on-command-no-prompt'.
+
+;;;; After 1.13:
+;;; Msb buffer list includes perl files
+;;; Indent-for-comment uses indent-to
+;;; Can write tag files using etags.
+
+;;;; After 1.14:
+;;; Recognizes (tries to ;-) {...} which are not blocks during indentation.
+;;; `cperl-close-paren-offset' affects ?\] too (and ?\} if not block)

+ "Major mode for editing Perl code.
+Expression and list commands understand all C brackets.
+Tab indents for Perl code.
+Paragraphs are separated by blank lines only.
+Delete converts tabs to spaces as it moves back.
+
+Various characters in Perl almost always come in pairs: {}, (), [],
+sometimes <>. When the user types the first, she gets the second as
+well, with optional special formatting done on {}. (Disabled by
+default.) You can always quote (with \\[quoted-insert]) the left
+\"paren\" to avoid the expansion. The processing of < is special,
+since most the time you mean \"less\". Cperl mode tries to guess
+whether you want to type pair <>, and inserts is if it
+appropriate. You can set `cperl-electric-parens' to the string that
+contains the parenths from the above list you want to be electrical.
+
+CPerl mode provides expansion of the Perl control constructs:
+ if, else, elsif, unless, while, until, for, and foreach.
+=========(Disabled by default, see `cperl-electric-keywords'.)
+The user types the keyword immediately followed by a space, which causes
+the construct to be expanded, and the user is positioned where she is most
+likely to want to be.
+eg. when the user types a space following \"if\" the following appears in
+the buffer:
+ if () { or if ()
+ } {
+ }
+and the cursor is between the parentheses. The user can then type some
+boolean expression within the parens. Having done that, typing
+\\[cperl-linefeed] places you, appropriately indented on a new line
+between the braces. If CPerl decides that you want to insert
+\"English\" style construct like
+ bite if angry;
+it will not do any expansion. See also help on variable
+`cperl-extra-newline-before-brace'.
+
+\\[cperl-linefeed] is a convinience replacement for typing carriage
+return. It places you in the next line with proper indentation, or if
+you type it inside the inline block of control construct, like
+ foreach (@lines) {print; print}
+and you are on a boundary of a statement inside braces, it will
+transform the construct into a multiline and will place you into an
+apporpriately indented blank line. If you need a usual
+`newline-and-indent' behaviour, it is on \\[newline-and-indent],
+see documentation on `cperl-electric-linefeed'.
+
+\\{cperl-mode-map}
+
+Setting the variable `cperl-font-lock' to t switches on
+font-lock-mode, `cperl-electric-lbrace-space' to t switches on
+electric space between $ and {, `cperl-electric-parens' is the string
+that contains parentheses that should be electric in CPerl, setting
+`cperl-electric-keywords' enables electric expansion of control
+structures in CPerl. `cperl-electric-linefeed' governs which one of
+two linefeed behavior is preferable. You can enable all these options
+simultaneously (recommended mode of use) by setting `cperl-hairy' to
+t. In this case you can switch separate options off by setting them
+to `null'.
+
+If your site has perl5 documentation in info format, you can use commands
+\\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it.
+These keys run commands `cperl-info-on-current-command' and
+`cperl-info-on-command', which one is which is controlled by variable
+`cperl-info-on-command-no-prompt' (in turn affected by `cperl-hairy').
+
+Variables controlling indentation style:
+ `cperl-tab-always-indent'
+ Non-nil means TAB in CPerl mode should always reindent the current line,
+ regardless of where in the line point is when the TAB command is used.
+ `cperl-auto-newline'
+ Non-nil means automatically newline before and after braces,
+ and after colons and semicolons, inserted in Perl code.
+ `cperl-indent-level'
+ Indentation of Perl statements within surrounding block.
+ The surrounding block's indentation is the indentation
+ of the line on which the open-brace appears.
+ `cperl-continued-statement-offset'
+ Extra indentation given to a substatement, such as the
+ then-clause of an if, or body of a while, or just a statement continuation.
+ `cperl-continued-brace-offset'
+ Extra indentation given to a brace that starts a substatement.
+ This is in addition to `cperl-continued-statement-offset'.
+ `cperl-brace-offset'
+ Extra indentation for line if it starts with an open brace.
+ `cperl-brace-imaginary-offset'
+ An open brace following other text is treated as if it the line started
+ this far to the right of the actual line indentation.
+ `cperl-label-offset'
+ Extra indentation for line that is a label.
+ `cperl-min-label-indent'
+ Minimal indentation for line that is a label.
+
+Settings for K&R and BSD indentation styles are
+ `cperl-indent-level' 5 8
+ `cperl-continued-statement-offset' 5 8
+ `cperl-brace-offset' -5 -8
+ `cperl-label-offset' -5 -8
+
+If `cperl-indent-level' is 0, the statement after opening brace in column 0 is indented on `cperl-brace-offset'+`cperl-continued-statement-offset'.
+
+Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'

-| Hi folks

-| Say, I'm trying to use perldb with emacs. I can invoke perldb
-| within emacs ok and get the window *perldb-foo* but when it asks
-| for "additional command line arguments" , no matter what I give it
-| I get the error message Symbol's function definition is void: make-
-| shell.
-|
-| The debugger , by itself, works fine but wanted to try out perldb in
-| emacs.
-
-This is a symptom of using Emacs 19.xx with perldb.el which was originally made
-for emacs version 18.xx. You can either install the emacs19 replacement for
-perldb that hooks it in with GUD (grand unified debugger), or apply the patches
-that I picked off of the net (I use the perldb replacement that uses GUD
-myself):

-XHere are my patches to perldb.el (the perl debugger mode that comes
-Xwith perl 4.0xx). Basically, all I've done is to hack perldb.el to
-Xuse comint.el stuff rather than the old shell.el stuff (i.e. change
-Xshell-mode-map to comint-mode-map).
-X
-XI've been using my patched version without problem, but if anyone sees
-Xsomething I've missed, please post or send e-mail.
-X
-X Thanks,

-
-;; To enter perl-mode automatically, add (autoload 'perl-mode "perl-mode")
-;; to your .emacs file and change the first line of your perl script to:
-;; #!/usr/bin/perl -- # -*-Perl-*-
-;; With argments to perl:
-;; #!/usr/bin/perl -P- # -*-Perl-*-
-;; To handle files included with do 'filename.pl';, add something like
-;; (setq auto-mode-alist (append (list (cons "\\.pl$" 'perl-mode))
-;; auto-mode-alist))
-;; to your .emacs file; otherwise the .pl suffix defaults to prolog-mode.
-
-;; This code is based on the 18.53 version c-mode.el, with extensive
-;; rewriting. Most of the features of c-mode survived intact.
-
-;; I added a new feature which adds functionality to TAB; it is controlled
-;; by the variable perl-tab-to-comment. With it enabled, TAB does the
-;; first thing it can from the following list: change the indentation;
-;; move past leading white space; delete an empty comment; reindent a
-;; comment; move to end of line; create an empty comment; tell you that
-;; the line ends in a quoted string, or has a # which should be a \#.
-
-;; If your machine is slow, you may want to remove some of the bindings
-;; to electric-perl-terminator. I changed the indenting defaults to be
-;; what Larry Wall uses in perl/lib, but left in all the options.
-
-;; I also tuned a few things: comments and labels starting in column
-;; zero are left there by indent-perl-exp; perl-beginning-of-function
-;; goes back to the first open brace/paren in column zero, the open brace
-;; in 'sub ... {', or the equal sign in 'format ... ='; indent-perl-exp
-;; (meta-^q) indents from the current line through the close of the next
-;; brace/paren, so you don't need to start exactly at a brace or paren.
-
-;; It may be good style to put a set of redundant braces around your
-;; main program. This will let you reindent it with meta-^q.
-
-;; Known problems (these are all caused by limitations in the elisp
-;; parsing routine (parse-partial-sexp), which was not designed for such
-;; a rich language; writing a more suitable parser would be a big job):
-;; 1) Regular expression delimitors do not act as quotes, so special
-;; characters such as `'"#:;[](){} may need to be backslashed
-;; in regular expressions and in both parts of s/// and tr///.
-;; 2) The globbing syntax <pattern> is not recognized, so special
-;; characters in the pattern string must be backslashed.
-;; 3) The q, qq, and << quoting operators are not recognized; see below.
-;; 4) \ (backslash) always quotes the next character, so '\' is
-;; treated as the start of a string. Use "\\" as a work-around.
-;; 5) To make variables such a $' and $#array work, perl-mode treats
-;; $ just like backslash, so '$' is the same as problem 5.
-;; 6) Unfortunately, treating $ like \ makes ${var} be treated as an
-;; unmatched }. See below.
-;; 7) When ' (quote) is used as a package name separator, perl-mode
-;; doesn't understand, and thinks it is seeing a quoted string.
-
-;; Here are some ugly tricks to bypass some of these problems: the perl
-;; expression /`/ (that's a back-tick) usually evaluates harmlessly,
-;; but will trick perl-mode into starting a quoted string, which
-;; can be ended with another /`/. Assuming you have no embedded
-;; back-ticks, this can used to help solve problem 3:
-;;
-;; /`/; $ugly = q?"'$?; /`/;
-;;
-;; To solve problem 6, add a /{/; before each use of ${var}:
-;; /{/; while (<${glob_me}>) ...
-;;
-;; Problem 7 is even worse, but this 'fix' does work :-(

-
-;; Description of perl -d interface:
-
-;; A facility is provided for the simultaneous display of the source code
-;; in one window, while using perldb to step through a function in the
-;; other. A small arrow in the source window, indicates the current
-;; line.
-
-;; Starting up:
-
-;; In order to use this facility, invoke the command PERLDB to obtain a
-;; shell window with the appropriate command bindings. You will be asked
-;; for the name of a file to run and additional command line arguments.
-;; Perldb will be invoked on this file, in a window named *perldb-foo*
-;; if the file is foo.
-
-;; M-s steps by one line, and redisplays the source file and line.
-
-;; You may easily create additional commands and bindings to interact
-;; with the display. For example to put the perl debugger command n on \M-n
-;; (def-perldb n "\M-n")
-
-;; This causes the emacs command perldb-next to be defined, and runs
-;; perldb-display-frame after the command.
-
-;; perldb-display-frame is the basic display function. It tries to display
-;; in the other window, the file and line corresponding to the current
-;; position in the perldb window. For example after a perldb-step, it would
-;; display the line corresponding to the position for the last step. Or
-;; if you have done a backtrace in the perldb buffer, and move the cursor
-;; into one of the frames, it would display the position corresponding to
-;; that frame.
-
-;; perldb-display-frame is invoked automatically when a filename-and-line-number
-;; appears in the output.

-Subject: Correction to Perl fatal error marking in GNU Emacs

-Reading my own message, it occurred to me that I didn't quite satisfy the
-request of stef@zweig.sun (Stephane Payrard):
-
-| Does anyone has extended perdb/perdb.el to position the
-| point to the first syntax error? It would be cool.
-
-What I posted is a way to use the "M-x compile" command to test perl scripts.
-(Needless to say, the script cannot be not interactive; you can't provide input
-to a *compilation* buffer). When creating new Perl programs, I use "M-x
-compile" until I'm sure that they are syntatically correct; if syntax errors
-occur, C-x` takes me to each in sequence. After I'm sure the syntax is
-correct, I start worrying about semantics, and switch to "M-x perldb" if
-necessary.
-
-Therefore, the stuff I posted works great with "M-x compile", but not at all
-with "M-x perldb".
-
-Next, let me update what I posted. I found that perl's die() command doesn't
-print the same format error message as perl does when it dies with a syntax
-error. If you put the following in your ".emacs" file, it causes C-x` to
-recognize both kinds of errors:
-
-(load-library "compile")
-(setq compilation-error-regexp
- "\\([^ :\n]+\\(: *\\|, line \\|(\\)[0-9]+\\)\\|\\([0-9]+ *of *[^ \n]+\\|[^ \n]+ \\(at \\)*line [0-9]+\\)")
-
-Last, so I don't look like a total fool, let me propose a way to satisfy
-Stephane Payrard's original request (repeated again):
-
-| Does anyone has extended perdb/perdb.el to position the
-| point to the first syntax error? It would be cool.
-
-I'm not satisfied with just the "first syntax error". Perl's parser is better
-than most about not getting out of sync; therefore, if it reports multiple
-errors, you can usually be assured they are all real errors.
-
-So... I hacked in the "next-error" function from "compile.el" to form
-"perldb-next-error". You can apply the patches at the end of this message
-to add "perldb-next-error" to your "perldb.el".
-
-Notes:
- 1) The patch binds "perldb-next-error" to C-x~ (because ~ is the shift
- of ` on my keyboard, and C-x~ is not yet taken in my version of EMACS).
-
- 2) "next-error" is meant to work on a single *compilation* buffer; any new
- "M-x compile" or "M-x grep" command will clear the old *compilation*
- buffer and reset the compilation-error parser to start at the top of the
- *compilation* buffer.
-
- "perldb-next-error", on the other hand, has to deal with multiple
- *perldb-<foo>* buffers, each of which keep growing. "perldb-next-error"
- correctly handles the constantly growing *perldb-<foo>* buffers by
- keeping track of the last reported error in the "current-perldb-buffer".
-
- Sadly however, when you invoke a new "M-x perldb" on a different Perl
- script, "perldb-next-error" will start parsing the new *perldb-<bar>*
- buffer at the top (even if it was previously parsed), and will completely
- lose the marker of the last reported error in *perldb-<foo>*.
-
- 3) "perldb-next-error" still uses "compilation-error-regexp" to find
- fatal errors. Therefore, both the "M-x compile"/C-x` scheme and
- the "M-x perldb"/C-x~ scheme can be used to find fatal errors that
- match the common "compilation-error-regexp". You *will* want to install
- that "compilation-error-regexp" stuff into your .emacs file.
-
- 4) The patch was developed and tested with GNU Emacs 18.55.
-
- 5) Since the patch was ripped off from compile.el, the code is (of
- course) subject to the GNU copyleft.
