32 ;; You can either fine-tune the bells and whistles of this mode or
33 ;; bulk enable them by putting
35 ;; (setq cperl-hairy t)
37 ;; in your .emacs file. (Emacs rulers do not consider it politically
38 ;; correct to make whistles enabled by default.)
40 ;; DO NOT FORGET to read micro-docs (available from `Perl' menu) <<<<<<
41 ;; or as help on variables `cperl-tips', `cperl-problems', <<<<<<
42 ;; `cperl-praise', `cperl-speed'. <<<<<<
44 ;; The mode information (on C-h m) provides some customization help.
45 ;; If you use font-lock feature of this mode, it is advisable to use
46 ;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock.
48 ;; Faces used now: three faces for first-class and second-class keywords
49 ;; and control flow words, one for each: comments, string, labels,
50 ;; functions definitions and packages, arrays, hashes, and variable
51 ;; definitions. If you do not see all these faces, your font-lock does
52 ;; not define them, so you need to define them manually.
54 ;; This mode supports font-lock, imenu and mode-compile. In the
55 ;; hairy version font-lock is on, but you should activate imenu
56 ;; yourself (note that mode-compile is not standard yet). Well, you
57 ;; can use imenu from keyboard anyway (M-x imenu), but it is better
58 ;; to bind it like that:
60 ;; (define-key global-map [M-S-down-mouse-3] 'imenu)
62 ;;; Font lock bugs as of v4.32:
64 ;; The following kinds of Perl code erroneously start strings:
66 ;; $opt::s $opt_s $opt{s} (s => ...) /\s+.../
67 ;; likewise with m, tr, y, q, qX instead of s

713 v20.2 up to the level of Emacs v20.3 - a must for a good Perl
714 mode.) As of beginning of 2003, XEmacs may provide a similar ability.

717 19.30), imenu-go.el from the same place. \(Look for other files there
718 too... ;-). Get a patch for imenu.el in 19.29. Note that for 19.30 and
719 later you should use choose-color.el *instead* of font-lock-extra.el

732 Also, one can generate a newer documentation running `pod2texi' converter
733 $CPAN/doc/manual/info/perl5/pod2texi-0.1.tar.gz
735 If you use imenu-go, run imenu on perl5-info buffer (you can do it
736 from Perl menu). If many files are related, generate TAGS files from
737 Tools/Tags submenu in Perl menu.
739 If some class structure is too complicated, use Tools/Hierarchy-view
740 from Perl menu, or hierarchic view of imenu. The second one uses the
741 current buffer only, the first one requires generation of TAGS from
742 Perl/Tools/Tags menu beforehand.

767 `fill-paragraph' on a comment may leave the point behind the
768 paragraph. It also triggers a bug in some versions of Emacs (CPerl tries
769 to detect it and bulk out).
771 See documentation of a variable `cperl-problems-old-emaxen' for the
772 problems which disappear if you upgrade Emacs to a reasonably new
773 version (20.3 for Emacs, and those of 2004 for XEmacs).")

776 "Description of problems in CPerl mode specific for older Emacs versions.
778 Emacs had a _very_ restricted syntax parsing engine until version
779 20.1. Most problems below are corrected starting from this version of
780 Emacs, and all of them should be fixed in version 20.3. (Or apply
781 patches to Emacs 19.33/34 - see tips.) XEmacs was very backward in
782 this respect (until 2003).
784 Note that even with newer Emacsen in some very rare cases the details
785 of interaction of `font-lock' and syntaxification may be not cleaned
786 up yet. You may get slightly different colors basing on the order of
787 fontification and syntaxification. Say, the initial faces is correct,
788 but editing the buffer breaks this.
790 Even with older Emacsen CPerl mode tries to corrects some Emacs
791 misunderstandings, however, for efficiency reasons the degree of
792 correction is different for different operations. The partially
793 corrected problems are: POD sections, here-documents, regexps. The
794 operations are: highlighting, indentation, electric keywords, electric
797 This may be confusing, since the regexp s#//#/#\; may be highlighted
798 as a comment, but it will be recognized as a regexp by the indentation
799 code. Or the opposite case, when a POD section is highlighted, but
800 may break the indentation of the following code (though indentation
801 should work if the balance of delimiters is not broken by POD).
803 The main trick (to make $ a \"backslash\") makes constructions like
804 ${aaa} look like unbalanced braces. The only trick I can think of is
805 to insert it as $ {aaa} (valid in perl5, not in perl4).
807 Similar problems arise in regexps, when /(\\s|$)/ should be rewritten
808 as /($|\\s)/. Note that such a transposition is not always possible.
810 The solution is to upgrade your Emacs or patch an older one. Note
811 that Emacs 20.2 has some bugs related to `syntax-table' text
812 properties. Patches are available on the main CPerl download site,
815 If these bugs cannot be fixed on your machine (say, you have an inferior
816 environment and cannot recompile), you may still disable all the fancy stuff

820 "Advantages of CPerl mode.
822 0) It uses the newest `syntax-table' property ;-);
824 1) It does 99% of Perl syntax correct (as opposed to 80-90% in Perl
825 mode - but the latter number may have improved too in last years) even
826 with old Emaxen which do not support `syntax-table' property.
828 When using `syntax-table' property for syntax assist hints, it should
829 handle 99.995% of lines correct - or somesuch. It automatically
830 updates syntax assist hints when you edit your script.
832 2) It is generally believed to be \"the most user-friendly Emacs
833 package\" whatever it may mean (I doubt that the people who say similar
834 things tried _all_ the rest of Emacs ;-), but this was not a lonely
837 3) Everything is customizable, one-by-one or in a big sweep;
839 4) It has many easily-accessable \"tools\":
840 a) Can run program, check syntax, start debugger;
841 b) Can lineup vertically \"middles\" of rows, like `=' in
844 c) Can insert spaces where this impoves readability (in one
845 interactive sweep over the buffer);
846 d) Has support for imenu, including:
847 1) Separate unordered list of \"interesting places\";
848 2) Separate TOC of POD sections;
849 3) Separate list of packages;
850 4) Hierarchical view of methods in (sub)packages;
851 5) and functions (by the full name - with package);
852 e) Has an interface to INFO docs for Perl; The interface is
853 very flexible, including shrink-wrapping of
854 documentation buffer/frame;
855 f) Has a builtin list of one-line explanations for perl constructs.
856 g) Can show these explanations if you stay long enough at the
857 corresponding place (or on demand);
858 h) Has an enhanced fontification (using 3 or 4 additional faces
859 comparing to font-lock - basically, different
860 namespaces in Perl have different colors);
861 i) Can construct TAGS basing on its knowledge of Perl syntax,
862 the standard menu has 6 different way to generate
863 TAGS (if \"by directory\", .xs files - with C-language
864 bindings - are included in the scan);
865 j) Can build a hierarchical view of classes (via imenu) basing
866 on generated TAGS file;
867 k) Has electric parentheses, electric newlines, uses Abbrev
868 for electric logical constructs
870 with different styles of expansion (context sensitive
871 to be not so bothering). Electric parentheses behave
872 \"as they should\" in a presence of a visible region.
873 l) Changes msb.el \"on the fly\" to insert a group \"Perl files\";
879 n) Highlights (by user-choice) either 3-delimiters constructs
880 (such as tr/a/b/), or regular expressions and `y/tr';
881 o) Highlights trailing whitespace;
882 p) Is able to manipulate Perl Regular Expressions to ease
883 conversion to a more readable form.
884 q) Can ispell POD sections and HERE-DOCs.
885 r) Understands comments and character classes inside regular
886 expressions; can find matching () and [] in a regular expression.
887 s) Allows indentation of //x-style regular expressions;
888 t) Highlights different symbols in regular expressions according
889 to their function; much less problems with backslashitis;
890 u) Allows to find regular expressions which contain interpolated parts.
892 5) The indentation engine was very smart, but most of tricks may be
893 not needed anymore with the support for `syntax-table' property. Has
894 progress indicator for indentation (with `imenu' loaded).
896 6) Indent-region improves inline-comments as well; also corrects
897 whitespace *inside* the conditional/loop constructs.
899 7) Fill-paragraph correctly handles multi-line comments;
901 8) Can switch to different indentation styles by one command, and restore
902 the settings present before the switch.
904 9) When doing indentation of control constructs, may correct
905 line-breaks/spacing between elements of the construct.
907 10) Uses a linear-time algorith for indentation of regions (on Emaxen with
908 capable syntax engines).
910 11) Syntax-highlight, indentation, sexp-recognition inside regular expressions.

914 "This is an incomplete compendium of what is available in other parts
915 of CPerl documentation. (Please inform me if I skept anything.)
917 There is a perception that CPerl is slower than alternatives. This part
918 of documentation is designed to overcome this misconception.
920 *By default* CPerl tries to enable the most comfortable settings.
921 From most points of view, correctly working package is infinitely more
922 comfortable than a non-correctly working one, thus by default CPerl
923 prefers correctness over speed. Below is the guide how to change
924 settings if your preferences are different.
926 A) Speed of loading the file. When loading file, CPerl may perform a
927 scan which indicates places which cannot be parsed by primitive Emacs
928 syntax-parsing routines, and marks them up so that either
930 A1) CPerl may work around these deficiencies (for big chunks, mostly
931 PODs and HERE-documents), or
932 A2) On capable Emaxen CPerl will use improved syntax-handlings
933 which reads mark-up hints directly.
935 The scan in case A2 is much more comprehensive, thus may be slower.
937 User can disable syntax-engine-helping scan of A2 by setting
938 `cperl-use-syntax-table-text-property'
939 variable to nil (if it is set to t).
941 One can disable the scan altogether (both A1 and A2) by setting
942 `cperl-pod-here-scan'
945 B) Speed of editing operations.
947 One can add a (minor) speedup to editing operations by setting
948 `cperl-use-syntax-table-text-property'
949 variable to nil (if it is set to t). This will disable
950 syntax-engine-helping scan, thus will make many more Perl
951 constructs be wrongly recognized by CPerl, thus may lead to
952 wrongly matched parentheses, wrong indentation, etc.
954 One can unset `cperl-syntaxify-unwind'. This might speed up editing
955 of, say, long POD sections.")

1524 Expression and list commands understand all C brackets.
1525 Tab indents for Perl code.
1526 Paragraphs are separated by blank lines only.
1527 Delete converts tabs to spaces as it moves back.
1529 Various characters in Perl almost always come in pairs: {}, (), [],
1530 sometimes <>. When the user types the first, she gets the second as
1531 well, with optional special formatting done on {}. (Disabled by
1532 default.) You can always quote (with \\[quoted-insert]) the left
1533 \"paren\" to avoid the expansion. The processing of < is special,
1534 since most the time you mean \"less\". CPerl mode tries to guess
1535 whether you want to type pair <>, and inserts is if it
1536 appropriate. You can set `cperl-electric-parens-string' to the string that
1537 contains the parenths from the above list you want to be electrical.
1538 Electricity of parenths is controlled by `cperl-electric-parens'.
1539 You may also set `cperl-electric-parens-mark' to have electric parens
1540 look for active mark and \"embrace\" a region if possible.'
1542 CPerl mode provides expansion of the Perl control constructs:
1544 if, else, elsif, unless, while, until, continue, do,
1545 for, foreach, formy and foreachmy.
1547 and POD directives (Disabled by default, see `cperl-electric-keywords'.)
1549 The user types the keyword immediately followed by a space, which
1550 causes the construct to be expanded, and the point is positioned where
1551 she is most likely to want to be. eg. when the user types a space
1552 following \"if\" the following appears in the buffer: if () { or if ()
1553 } { } and the cursor is between the parentheses. The user can then
1554 type some boolean expression within the parens. Having done that,
1555 typing \\[cperl-linefeed] places you - appropriately indented - on a
1556 new line between the braces (if you typed \\[cperl-linefeed] in a POD
1557 directive line, then appropriate number of new lines is inserted).
1559 If CPerl decides that you want to insert \"English\" style construct like
1563 it will not do any expansion. See also help on variable
1564 `cperl-extra-newline-before-brace'. (Note that one can switch the
1565 help message on expansion by setting `cperl-message-electric-keyword'
1568 \\[cperl-linefeed] is a convenience replacement for typing carriage
1569 return. It places you in the next line with proper indentation, or if
1570 you type it inside the inline block of control construct, like
1572 foreach (@lines) {print; print}
1574 and you are on a boundary of a statement inside braces, it will
1575 transform the construct into a multiline and will place you into an
1576 appropriately indented blank line. If you need a usual
1577 `newline-and-indent' behavior, it is on \\[newline-and-indent],
1578 see documentation on `cperl-electric-linefeed'.
1580 Use \\[cperl-invert-if-unless] to change a construction of the form
1590 Setting the variable `cperl-font-lock' to t switches on font-lock-mode
1591 \(even with older Emacsen), `cperl-electric-lbrace-space' to t switches
1592 on electric space between $ and {, `cperl-electric-parens-string' is
1593 the string that contains parentheses that should be electric in CPerl
1594 \(see also `cperl-electric-parens-mark' and `cperl-electric-parens'),
1595 setting `cperl-electric-keywords' enables electric expansion of
1596 control structures in CPerl. `cperl-electric-linefeed' governs which
1597 one of two linefeed behavior is preferable. You can enable all these
1598 options simultaneously (recommended mode of use) by setting
1599 `cperl-hairy' to t. In this case you can switch separate options off
1600 by setting them to `null'. Note that one may undo the extra
1601 whitespace inserted by semis and braces in `auto-newline'-mode by
1602 consequent \\[cperl-electric-backspace].
1604 If your site has perl5 documentation in info format, you can use commands
1605 \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it.
1606 These keys run commands `cperl-info-on-current-command' and
1607 `cperl-info-on-command', which one is which is controlled by variable
1608 `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings'
1609 \(in turn affected by `cperl-hairy').
1611 Even if you have no info-format documentation, short one-liner-style
1612 help is available on \\[cperl-get-help], and one can run perldoc or
1615 It is possible to show this help automatically after some idle time.
1616 This is regulated by variable `cperl-lazy-help-time'. Default with
1617 `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5
1618 secs idle time . It is also possible to switch this on/off from the
1619 menu, or via \\[cperl-toggle-autohelp]. Requires `run-with-idle-timer'.
1621 Use \\[cperl-lineup] to vertically lineup some construction - put the
1622 beginning of the region at the start of construction, and make region
1623 span the needed amount of lines.
1625 Variables `cperl-pod-here-scan', `cperl-pod-here-fontify',
1626 `cperl-pod-face', `cperl-pod-head-face' control processing of POD and
1627 here-docs sections. With capable Emaxen results of scan are used
1628 for indentation too, otherwise they are used for highlighting only.
1630 Variables controlling indentation style:
1631 `cperl-tab-always-indent'
1632 Non-nil means TAB in CPerl mode should always reindent the current line,
1633 regardless of where in the line point is when the TAB command is used.
1634 `cperl-indent-left-aligned-comments'
1635 Non-nil means that the comment starting in leftmost column should indent.
1636 `cperl-auto-newline'
1637 Non-nil means automatically newline before and after braces,
1638 and after colons and semicolons, inserted in Perl code. The following
1639 \\[cperl-electric-backspace] will remove the inserted whitespace.
1640 Insertion after colons requires both this variable and
1641 `cperl-auto-newline-after-colon' set.
1642 `cperl-auto-newline-after-colon'
1643 Non-nil means automatically newline even after colons.
1644 Subject to `cperl-auto-newline' setting.
1645 `cperl-indent-level'
1646 Indentation of Perl statements within surrounding block.
1647 The surrounding block's indentation is the indentation
1648 of the line on which the open-brace appears.
1649 `cperl-continued-statement-offset'
1650 Extra indentation given to a substatement, such as the
1651 then-clause of an if, or body of a while, or just a statement continuation.
1652 `cperl-continued-brace-offset'
1653 Extra indentation given to a brace that starts a substatement.
1654 This is in addition to `cperl-continued-statement-offset'.
1655 `cperl-brace-offset'
1656 Extra indentation for line if it starts with an open brace.
1657 `cperl-brace-imaginary-offset'
1658 An open brace following other text is treated as if it the line started
1659 this far to the right of the actual line indentation.
1660 `cperl-label-offset'
1661 Extra indentation for line that is a label.
1662 `cperl-min-label-indent'
1663 Minimal indentation for line that is a label.
1665 Settings for classic indent-styles: K&R BSD=C++ GNU PerlStyle=Whitesmith
1666 `cperl-indent-level' 5 4 2 4
1667 `cperl-brace-offset' 0 0 0 0
1668 `cperl-continued-brace-offset' -5 -4 0 0
1669 `cperl-label-offset' -5 -4 -2 -4
1670 `cperl-continued-statement-offset' 5 4 2 4
1672 CPerl knows several indentation styles, and may bulk set the
1673 corresponding variables. Use \\[cperl-set-style] to do this. Use
1674 \\[cperl-set-style-back] to restore the memorized preexisting values
1675 \(both available from menu). See examples in `cperl-style-examples'.
1677 Part of the indentation style is how different parts of if/elsif/else
1678 statements are broken into lines; in CPerl, this is reflected on how
1679 templates for these constructs are created (controlled by
1680 `cperl-extra-newline-before-brace'), and how reflow-logic should treat \"continuation\" blocks of else/elsif/continue, controlled by the same variable,
1681 and by `cperl-extra-newline-before-brace-multiline',
1682 `cperl-merge-trailing-else', `cperl-indent-region-fix-constructs'.
1684 If `cperl-indent-level' is 0, the statement after opening brace in
1685 column 0 is indented on
1686 `cperl-brace-offset'+`cperl-continued-statement-offset'.
1688 Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'
1691 DO NOT FORGET to read micro-docs (available from `Perl' menu)
1692 or as help on variables `cperl-tips', `cperl-problems',
1693 `cperl-praise', `cperl-speed'."
