| 31 | ;; You can either fine-tune the bells and whistles of this mode or |
| 32 | ;; bulk enable them by putting |
| 33 | |
| 34 | ;; (setq cperl-hairy t) |
| 35 | |
| 36 | ;; in your .emacs file. (Emacs rulers do not consider it politically |
| 37 | ;; correct to make whistles enabled by default.) |
| 38 | |
| 39 | ;; DO NOT FORGET to read micro-docs (available from `Perl' menu) <<<<<< |
| 40 | ;; or as help on variables `cperl-tips', `cperl-problems', <<<<<< |
| 41 | ;; `cperl-praise', `cperl-speed'. <<<<<< |
| 42 | |
| 43 | ;; The mode information (on C-h m) provides some customization help. |
| 44 | ;; If you use font-lock feature of this mode, it is advisable to use |
| 45 | ;; either lazy-lock-mode or fast-lock-mode. I prefer lazy-lock. |
| 46 | |
| 47 | ;; Faces used now: three faces for first-class and second-class keywords |
| 48 | ;; and control flow words, one for each: comments, string, labels, |
| 49 | ;; functions definitions and packages, arrays, hashes, and variable |
| 50 | ;; definitions. If you do not see all these faces, your font-lock does |
| 51 | ;; not define them, so you need to define them manually. |
| 52 | |
| 53 | ;; This mode supports font-lock, imenu and mode-compile. In the |
| 54 | ;; hairy version font-lock is on, but you should activate imenu |
| 55 | ;; yourself (note that mode-compile is not standard yet). Well, you |
| 56 | ;; can use imenu from keyboard anyway (M-x imenu), but it is better |
| 57 | ;; to bind it like that: |
| 58 | |
| 59 | ;; (define-key global-map [M-S-down-mouse-3] 'imenu) |
| 60 | |
| 61 | ;;; Font lock bugs as of v4.32: |
| 62 | |
| 63 | ;; The following kinds of Perl code erroneously start strings: |
| 64 | ;; \$` \$' \$" |
| 65 | ;; $opt::s $opt_s $opt{s} (s => ...) /\s+.../ |
| 66 | ;; likewise with m, tr, y, q, qX instead of s |

| 766 | `fill-paragraph' on a comment may leave the point behind the |

| 771 | problems which disappear if you upgrade Emacs to a reasonably new |
| 772 | version (20.3 for Emacs, and those of 2004 for XEmacs).") |

| 774 | (defvar cperl-problems-old-emaxen 'please-ignore-this-line |
| 775 | "Description of problems in CPerl mode specific for older Emacs versions. |
| 776 | |
| 777 | Emacs had a _very_ restricted syntax parsing engine until version |
| 778 | 20.1. Most problems below are corrected starting from this version of |
| 779 | Emacs, and all of them should be fixed in version 20.3. (Or apply |
| 780 | patches to Emacs 19.33/34 - see tips.) XEmacs was very backward in |
| 781 | this respect (until 2003). |
| 782 | |
| 783 | Note that even with newer Emacsen in some very rare cases the details |
| 784 | of interaction of `font-lock' and syntaxification may be not cleaned |
| 785 | up yet. You may get slightly different colors basing on the order of |
| 786 | fontification and syntaxification. Say, the initial faces is correct, |
| 787 | but editing the buffer breaks this. |
| 788 | |
| 789 | Even with older Emacsen CPerl mode tries to corrects some Emacs |
| 790 | misunderstandings, however, for efficiency reasons the degree of |
| 791 | correction is different for different operations. The partially |
| 792 | corrected problems are: POD sections, here-documents, regexps. The |
| 793 | operations are: highlighting, indentation, electric keywords, electric |
| 794 | braces. |
| 795 | |
| 796 | This may be confusing, since the regexp s#//#/#\; may be highlighted |
| 797 | as a comment, but it will be recognized as a regexp by the indentation |
| 798 | code. Or the opposite case, when a POD section is highlighted, but |
| 799 | may break the indentation of the following code (though indentation |
| 800 | should work if the balance of delimiters is not broken by POD). |
| 801 | |
| 802 | The main trick (to make $ a \"backslash\") makes constructions like |
| 803 | ${aaa} look like unbalanced braces. The only trick I can think of is |
| 804 | to insert it as $ {aaa} (valid in perl5, not in perl4). |
| 805 | |
| 806 | Similar problems arise in regexps, when /(\\s|$)/ should be rewritten |
| 807 | as /($|\\s)/. Note that such a transposition is not always possible. |
| 808 | |
| 809 | The solution is to upgrade your Emacs or patch an older one. Note |
| 810 | that Emacs 20.2 has some bugs related to `syntax-table' text |
| 811 | properties. Patches are available on the main CPerl download site, |
| 812 | and on CPAN. |
| 813 | |
| 814 | If these bugs cannot be fixed on your machine (say, you have an inferior |
| 815 | environment and cannot recompile), you may still disable all the fancy stuff |
| 816 | via `cperl-use-syntax-table-text-property'.") |

| 823 | 1) It does 99% of Perl syntax correct (as opposed to 80-90% in Perl |
| 824 | mode - but the latter number may have improved too in last years) even |
| 825 | with old Emaxen which do not support `syntax-table' property. |
| 826 | |
| 827 | When using `syntax-table' property for syntax assist hints, it should |

| 832 | package\" whatever it may mean (I doubt that the people who say similar |
| 833 | things tried _all_ the rest of Emacs ;-), but this was not a lonely |
| 834 | voice); |
| 835 | |
| 836 | 3) Everything is customizable, one-by-one or in a big sweep; |
| 837 | |
| 838 | 4) It has many easily-accessible \"tools\": |
| 839 | a) Can run program, check syntax, start debugger; |
| 840 | b) Can lineup vertically \"middles\" of rows, like `=' in |
| 841 | a = b; |
| 842 | cc = d; |
| 843 | c) Can insert spaces where this impoves readability (in one |
| 844 | interactive sweep over the buffer); |
| 845 | d) Has support for imenu, including: |
| 846 | 1) Separate unordered list of \"interesting places\"; |
| 847 | 2) Separate TOC of POD sections; |
| 848 | 3) Separate list of packages; |
| 849 | 4) Hierarchical view of methods in (sub)packages; |
| 850 | 5) and functions (by the full name - with package); |
| 851 | e) Has an interface to INFO docs for Perl; The interface is |
| 852 | very flexible, including shrink-wrapping of |
| 853 | documentation buffer/frame; |
| 854 | f) Has a builtin list of one-line explanations for perl constructs. |

| 857 | h) Has an enhanced fontification (using 3 or 4 additional faces |
| 858 | comparing to font-lock - basically, different |
| 859 | namespaces in Perl have different colors); |
| 860 | i) Can construct TAGS basing on its knowledge of Perl syntax, |
| 861 | the standard menu has 6 different way to generate |
| 862 | TAGS (if \"by directory\", .xs files - with C-language |
| 863 | bindings - are included in the scan); |
| 864 | j) Can build a hierarchical view of classes (via imenu) basing |
| 865 | on generated TAGS file; |
| 866 | k) Has electric parentheses, electric newlines, uses Abbrev |
| 867 | for electric logical constructs |
| 868 | while () {} |
| 869 | with different styles of expansion (context sensitive |
| 870 | to be not so bothering). Electric parentheses behave |
| 871 | \"as they should\" in a presence of a visible region. |
| 872 | l) Changes msb.el \"on the fly\" to insert a group \"Perl files\"; |
| 873 | m) Can convert from |
| 874 | if (A) { B } |
| 875 | to |
| 876 | B if A; |
| 877 | |
| 878 | n) Highlights (by user-choice) either 3-delimiters constructs |
| 879 | (such as tr/a/b/), or regular expressions and `y/tr'; |
| 880 | o) Highlights trailing whitespace; |
| 881 | p) Is able to manipulate Perl Regular Expressions to ease |
| 882 | conversion to a more readable form. |
| 883 | q) Can ispell POD sections and HERE-DOCs. |
| 884 | r) Understands comments and character classes inside regular |
| 885 | expressions; can find matching () and [] in a regular expression. |
| 886 | s) Allows indentation of //x-style regular expressions; |
| 887 | t) Highlights different symbols in regular expressions according |
| 888 | to their function; much less problems with backslashitis; |
| 889 | u) Allows to find regular expressions which contain interpolated parts. |
| 890 | |
| 891 | 5) The indentation engine was very smart, but most of tricks may be |
| 892 | not needed anymore with the support for `syntax-table' property. Has |
| 893 | progress indicator for indentation (with `imenu' loaded). |
| 894 | |
| 895 | 6) Indent-region improves inline-comments as well; also corrects |
| 896 | whitespace *inside* the conditional/loop constructs. |
| 897 | |
| 898 | 7) Fill-paragraph correctly handles multi-line comments; |
| 899 | |
| 900 | 8) Can switch to different indentation styles by one command, and restore |
| 901 | the settings present before the switch. |
| 902 | |
| 903 | 9) When doing indentation of control constructs, may correct |
| 904 | line-breaks/spacing between elements of the construct. |
| 905 | |
| 906 | 10) Uses a linear-time algorith for indentation of regions (on Emaxen with |
| 907 | capable syntax engines). |
| 908 | |
| 909 | 11) Syntax-highlight, indentation, sexp-recognition inside regular expressions. |

| 913 | "This is an incomplete compendium of what is available in other parts |
| 914 | of CPerl documentation. (Please inform me if I skept anything.) |
| 915 | |
| 916 | There is a perception that CPerl is slower than alternatives. This part |
| 917 | of documentation is designed to overcome this misconception. |
| 918 | |
| 919 | *By default* CPerl tries to enable the most comfortable settings. |
| 920 | From most points of view, correctly working package is infinitely more |
| 921 | comfortable than a non-correctly working one, thus by default CPerl |
| 922 | prefers correctness over speed. Below is the guide how to change |
| 923 | settings if your preferences are different. |
| 924 | |
| 925 | A) Speed of loading the file. When loading file, CPerl may perform a |
| 926 | scan which indicates places which cannot be parsed by primitive Emacs |
| 927 | syntax-parsing routines, and marks them up so that either |
| 928 | |
| 929 | A1) CPerl may work around these deficiencies (for big chunks, mostly |
| 930 | PODs and HERE-documents), or |
| 931 | A2) On capable Emaxen CPerl will use improved syntax-handlings |
| 932 | which reads mark-up hints directly. |
| 933 | |
| 934 | The scan in case A2 is much more comprehensive, thus may be slower. |
| 935 | |
| 936 | User can disable syntax-engine-helping scan of A2 by setting |
| 937 | `cperl-use-syntax-table-text-property' |
| 938 | variable to nil (if it is set to t). |
| 939 | |
| 940 | One can disable the scan altogether (both A1 and A2) by setting |
| 941 | `cperl-pod-here-scan' |
| 942 | to nil. |
| 943 | |
| 944 | B) Speed of editing operations. |
| 945 | |
| 946 | One can add a (minor) speedup to editing operations by setting |
| 947 | `cperl-use-syntax-table-text-property' |
| 948 | variable to nil (if it is set to t). This will disable |
| 949 | syntax-engine-helping scan, thus will make many more Perl |
| 950 | constructs be wrongly recognized by CPerl, thus may lead to |
| 951 | wrongly matched parentheses, wrong indentation, etc. |
| 952 | |
| 953 | One can unset `cperl-syntaxify-unwind'. This might speed up editing |
| 954 | of, say, long POD sections.") |

| 1527 | "Major mode for editing Perl code. |
| 1528 | Expression and list commands understand all C brackets. |
| 1529 | Tab indents for Perl code. |
| 1530 | Paragraphs are separated by blank lines only. |
| 1531 | Delete converts tabs to spaces as it moves back. |
| 1532 | |
| 1533 | Various characters in Perl almost always come in pairs: {}, (), [], |
| 1534 | sometimes <>. When the user types the first, she gets the second as |
| 1535 | well, with optional special formatting done on {}. (Disabled by |
| 1536 | default.) You can always quote (with \\[quoted-insert]) the left |
| 1537 | \"paren\" to avoid the expansion. The processing of < is special, |
| 1538 | since most the time you mean \"less\". CPerl mode tries to guess |
| 1539 | whether you want to type pair <>, and inserts is if it |
| 1540 | appropriate. You can set `cperl-electric-parens-string' to the string that |
| 1541 | contains the parenths from the above list you want to be electrical. |
| 1542 | Electricity of parenths is controlled by `cperl-electric-parens'. |
| 1543 | You may also set `cperl-electric-parens-mark' to have electric parens |
| 1544 | look for active mark and \"embrace\" a region if possible.' |
| 1545 | |
| 1546 | CPerl mode provides expansion of the Perl control constructs: |
| 1547 | |
| 1548 | if, else, elsif, unless, while, until, continue, do, |
| 1549 | for, foreach, formy and foreachmy. |
| 1550 | |
| 1551 | and POD directives (Disabled by default, see `cperl-electric-keywords'.) |
| 1552 | |
| 1553 | The user types the keyword immediately followed by a space, which |
| 1554 | causes the construct to be expanded, and the point is positioned where |
| 1555 | she is most likely to want to be. eg. when the user types a space |
| 1556 | following \"if\" the following appears in the buffer: if () { or if () |
| 1557 | } { } and the cursor is between the parentheses. The user can then |
| 1558 | type some boolean expression within the parens. Having done that, |
| 1559 | typing \\[cperl-linefeed] places you - appropriately indented - on a |
| 1560 | new line between the braces (if you typed \\[cperl-linefeed] in a POD |
| 1561 | directive line, then appropriate number of new lines is inserted). |
| 1562 | |
| 1563 | If CPerl decides that you want to insert \"English\" style construct like |
| 1564 | |
| 1565 | bite if angry; |
| 1566 | |
| 1567 | it will not do any expansion. See also help on variable |
| 1568 | `cperl-extra-newline-before-brace'. (Note that one can switch the |
| 1569 | help message on expansion by setting `cperl-message-electric-keyword' |
| 1570 | to nil.) |
| 1571 | |
| 1572 | \\[cperl-linefeed] is a convenience replacement for typing carriage |
| 1573 | return. It places you in the next line with proper indentation, or if |
| 1574 | you type it inside the inline block of control construct, like |
| 1575 | |
| 1576 | foreach (@lines) {print; print} |
| 1577 | |
| 1578 | and you are on a boundary of a statement inside braces, it will |
| 1579 | transform the construct into a multiline and will place you into an |
| 1580 | appropriately indented blank line. If you need a usual |
| 1581 | `newline-and-indent' behavior, it is on \\[newline-and-indent], |
| 1582 | see documentation on `cperl-electric-linefeed'. |
| 1583 | |
| 1584 | Use \\[cperl-invert-if-unless] to change a construction of the form |
| 1585 | |
| 1586 | if (A) { B } |
| 1587 | |
| 1588 | into |
| 1589 | |
| 1590 | B if A; |
| 1591 | |
| 1592 | \\{cperl-mode-map} |
| 1593 | |
| 1594 | Setting the variable `cperl-font-lock' to t switches on font-lock-mode |
| 1595 | \(even with older Emacsen), `cperl-electric-lbrace-space' to t switches |
| 1596 | on electric space between $ and {, `cperl-electric-parens-string' is |
| 1597 | the string that contains parentheses that should be electric in CPerl |
| 1598 | \(see also `cperl-electric-parens-mark' and `cperl-electric-parens'), |
| 1599 | setting `cperl-electric-keywords' enables electric expansion of |
| 1600 | control structures in CPerl. `cperl-electric-linefeed' governs which |
| 1601 | one of two linefeed behavior is preferable. You can enable all these |
| 1602 | options simultaneously (recommended mode of use) by setting |
| 1603 | `cperl-hairy' to t. In this case you can switch separate options off |
| 1604 | by setting them to `null'. Note that one may undo the extra |
| 1605 | whitespace inserted by semis and braces in `auto-newline'-mode by |
| 1606 | consequent \\[cperl-electric-backspace]. |
| 1607 | |
| 1608 | If your site has perl5 documentation in info format, you can use commands |
| 1609 | \\[cperl-info-on-current-command] and \\[cperl-info-on-command] to access it. |
| 1610 | These keys run commands `cperl-info-on-current-command' and |
| 1611 | `cperl-info-on-command', which one is which is controlled by variable |
| 1612 | `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings' |
| 1613 | \(in turn affected by `cperl-hairy'). |
| 1614 | |
| 1615 | Even if you have no info-format documentation, short one-liner-style |
| 1616 | help is available on \\[cperl-get-help], and one can run perldoc or |
| 1617 | man via menu. |
| 1618 | |
| 1619 | It is possible to show this help automatically after some idle time. |
| 1620 | This is regulated by variable `cperl-lazy-help-time'. Default with |
| 1621 | `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5 |
| 1622 | secs idle time . It is also possible to switch this on/off from the |
| 1623 | menu, or via \\[cperl-toggle-autohelp]. Requires `run-with-idle-timer'. |
| 1624 | |
| 1625 | Use \\[cperl-lineup] to vertically lineup some construction - put the |
| 1626 | beginning of the region at the start of construction, and make region |
| 1627 | span the needed amount of lines. |
| 1628 | |
| 1629 | Variables `cperl-pod-here-scan', `cperl-pod-here-fontify', |
| 1630 | `cperl-pod-face', `cperl-pod-head-face' control processing of POD and |
| 1631 | here-docs sections. With capable Emaxen results of scan are used |
| 1632 | for indentation too, otherwise they are used for highlighting only. |
| 1633 | |
| 1634 | Variables controlling indentation style: |
| 1635 | `cperl-tab-always-indent' |
| 1636 | Non-nil means TAB in CPerl mode should always reindent the current line, |
| 1637 | regardless of where in the line point is when the TAB command is used. |
| 1638 | `cperl-indent-left-aligned-comments' |
| 1639 | Non-nil means that the comment starting in leftmost column should indent. |
| 1640 | `cperl-auto-newline' |
| 1641 | Non-nil means automatically newline before and after braces, |
| 1642 | and after colons and semicolons, inserted in Perl code. The following |
| 1643 | \\[cperl-electric-backspace] will remove the inserted whitespace. |
| 1644 | Insertion after colons requires both this variable and |
| 1645 | `cperl-auto-newline-after-colon' set. |
| 1646 | `cperl-auto-newline-after-colon' |
| 1647 | Non-nil means automatically newline even after colons. |
| 1648 | Subject to `cperl-auto-newline' setting. |
| 1649 | `cperl-indent-level' |
| 1650 | Indentation of Perl statements within surrounding block. |
| 1651 | The surrounding block's indentation is the indentation |
| 1652 | of the line on which the open-brace appears. |
| 1653 | `cperl-continued-statement-offset' |
| 1654 | Extra indentation given to a substatement, such as the |
| 1655 | then-clause of an if, or body of a while, or just a statement continuation. |
| 1656 | `cperl-continued-brace-offset' |
| 1657 | Extra indentation given to a brace that starts a substatement. |
| 1658 | This is in addition to `cperl-continued-statement-offset'. |
| 1659 | `cperl-brace-offset' |
| 1660 | Extra indentation for line if it starts with an open brace. |
| 1661 | `cperl-brace-imaginary-offset' |
| 1662 | An open brace following other text is treated as if it the line started |
| 1663 | this far to the right of the actual line indentation. |
| 1664 | `cperl-label-offset' |
| 1665 | Extra indentation for line that is a label. |
| 1666 | `cperl-min-label-indent' |
| 1667 | Minimal indentation for line that is a label. |
| 1668 | |
| 1669 | Settings for classic indent-styles: K&R BSD=C++ GNU PerlStyle=Whitesmith |
| 1670 | `cperl-indent-level' 5 4 2 4 |
| 1671 | `cperl-brace-offset' 0 0 0 0 |
| 1672 | `cperl-continued-brace-offset' -5 -4 0 0 |
| 1673 | `cperl-label-offset' -5 -4 -2 -4 |
| 1674 | `cperl-continued-statement-offset' 5 4 2 4 |
| 1675 | |
| 1676 | CPerl knows several indentation styles, and may bulk set the |
| 1677 | corresponding variables. Use \\[cperl-set-style] to do this. Use |
| 1678 | \\[cperl-set-style-back] to restore the memorized preexisting values |
| 1679 | \(both available from menu). See examples in `cperl-style-examples'. |
| 1680 | |
| 1681 | Part of the indentation style is how different parts of if/elsif/else |
| 1682 | statements are broken into lines; in CPerl, this is reflected on how |
| 1683 | templates for these constructs are created (controlled by |
| 1684 | `cperl-extra-newline-before-brace'), and how reflow-logic should treat |
| 1685 | \"continuation\" blocks of else/elsif/continue, controlled by the same |
| 1686 | variable, and by `cperl-extra-newline-before-brace-multiline', |
| 1687 | `cperl-merge-trailing-else', `cperl-indent-region-fix-constructs'. |
| 1688 | |
| 1689 | If `cperl-indent-level' is 0, the statement after opening brace in |
| 1690 | column 0 is indented on |
| 1691 | `cperl-brace-offset'+`cperl-continued-statement-offset'. |
| 1692 | |
| 1693 | Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook' |
| 1694 | with no args. |
| 1695 | |
| 1696 | DO NOT FORGET to read micro-docs (available from `Perl' menu) |
| 1697 | or as help on variables `cperl-tips', `cperl-problems', |
| 1698 | `cperl-praise', `cperl-speed'." |
