568 Subdirectory `cperl-mode' may contain yet newer development releases and/or
569 patches to related files.
571 For best results apply to an older Emacs the patches from
572 ftp://ftp.math.ohio-state.edu/pub/users/ilya/cperl-mode/patches
573 \(this upgrades syntax-parsing abilities of RMS Emaxen v19.34 and
574 v20.2 up to the level of RMS Emacs v20.3 - a must for a good Perl
575 mode.) You will not get much from XEmacs, it's syntax abilities are
576 too primitive.
578 Get support packages choose-color.el (or font-lock-extra.el before
579 19.30), imenu-go.el from the same place. \(Look for other files there
580 too... ;-). Get a patch for imenu.el in 19.29. Note that for 19.30 and
581 later you should use choose-color.el *instead* of font-lock-extra.el
582 \(and you will not get smart highlighting in C :-().
584 Note that to enable Compile choices in the menu you need to install
585 mode-compile.el.
587 Get perl5-info from
588 $CPAN/doc/manual/info/perl-info.tar.gz
589 older version was on
590 http://www.metronet.com:70/9/perlinfo/perl5/manual/perl5-info.tar.gz
592 If you use imenu-go, run imenu on perl5-info buffer (you can do it
593 from Perl menu). If many files are related, generate TAGS files from
594 Tools/Tags submenu in Perl menu.
596 If some class structure is too complicated, use Tools/Hierarchy-view
597 from Perl menu, or hierarchic view of imenu. The second one uses the
598 current buffer only, the first one requires generation of TAGS from
599 Perl/Tools/Tags menu beforehand.
601 Run Perl/Tools/Insert-spaces-if-needed to fix your lazy typing.
603 Switch auto-help on/off with Perl/Tools/Auto-help.
605 Though with contemporary Emaxen CPerl mode should maintain the correct
606 parsing of Perl even when editing, sometimes it may be lost. Fix this by
608 M-x norm RET
610 In cases of more severe confusion sometimes it is helpful to do
612 M-x load-l RET cperl-mode RET
613 M-x norm RET
615 Before reporting (non-)problems look in the problem section of online
619 "Some faces will not be shown on some versions of Emacs unless you
620 install choose-color.el, available from
621 ftp://ftp.math.ohio-state.edu/pub/users/ilya/emacs/
623 Emacs had a _very_ restricted syntax parsing engine until RMS's Emacs
624 20.1. Most problems below are corrected starting from this version of
625 Emacs, and all of them should go with (future) RMS's version 20.3.
627 Note that even with newer Emacsen interaction of `font-lock' and
628 syntaxification is not cleaned up. You may get slightly different
629 colors basing on the order of fontification and syntaxification. This
630 might be corrected by setting `cperl-syntaxify-by-font-lock' to t, but
631 the corresponding code is still extremely buggy.
633 Even with older Emacsen CPerl mode tries to corrects some Emacs
634 misunderstandings, however, for efficiency reasons the degree of
635 correction is different for different operations. The partially
636 corrected problems are: POD sections, here-documents, regexps. The
637 operations are: highlighting, indentation, electric keywords, electric
638 braces.
640 This may be confusing, since the regexp s#//#/#\; may be highlighted
641 as a comment, but it will be recognized as a regexp by the indentation
642 code. Or the opposite case, when a pod section is highlighted, but
643 may break the indentation of the following code (though indentation
644 should work if the balance of delimiters is not broken by POD).
647 ${aaa} look like unbalanced braces. The only trick I can think of is
648 to insert it as $ {aaa} (legal in perl5, not in perl4).
653 The solution is to upgrade your Emacs or patch an older one. Note
654 that RMS's 20.2 has some bugs related to `syntax-table' text
655 properties. Patches are available on the main CPerl download site,
656 and on CPAN.
658 If these bugs cannot be fixed on your machine (say, you have an inferior
659 environment and cannot recompile), you may still disable all the fancy stuff
663 "As you know from `problems' section, Perl syntax is too hard for CPerl on
664 older Emacsen. Here is what you can do if you cannot upgrade, or if
665 you want to switch off these capabilities on RMS Emacs 20.2 (+patches) or 20.3
666 or better. Please skip this docs if you run a capable Emacs already.
668 Most of the time, if you write your own code, you may find an equivalent
669 \(and almost as readable) expression (what is discussed below is usually
670 not relevant on newer Emacsen, since they can do it automatically).
672 Try to help CPerl: add comments with embedded quotes to fix CPerl
673 misunderstandings about the end of quotation:
675 $a='500$'; # ';
678 character (this saves a life a lot of times in CPerl), thus due to
679 Emacs parsing rules it does not consider tick (i.e., ' ) after a
680 dollar as a closing one, but as a usual character. This is usually
681 correct, but not in the above context.
683 Even with older Emacsen the indentation code is pretty wise. The only
684 drawback is that it relied on Emacs parsing to find matching
685 parentheses. And Emacs *could not* match parentheses in Perl 100%
686 correctly. So
687 1 if s#//#/#;
688 would not break indentation, but
689 1 if ( s#//#/# );
690 would. Upgrade.
692 By similar reasons
694 would confuse CPerl a lot.
696 If you still get wrong indentation in situation that you think the
697 code should be able to parse, try:
699 a) Check what Emacs thinks about balance of your parentheses.
700 b) Supply the code to me (IZ).
702 Pods were treated _very_ rudimentally. Here-documents were not
703 treated at all (except highlighting and inhibiting indentation). Upgrade.
705 To speed up coloring the following compromises exist:
706 a) sub in $mypackage::sub may be highlighted.
707 b) -z in [a-z] may be highlighted.
711 Imenu in 19.31 is broken. Set `imenu-use-keymap-menu' to t, and remove
712 `car' before `imenu-choose-buffer-index' in `imenu'.
713 `imenu-add-to-menubar' in 20.2 is broken.
715 A lot of things on XEmacs may be broken too, judging by bug reports I
716 recieve. Note that some releases of XEmacs are better than the others
720 "RMS asked me to list good things about CPerl. Here they go:
722 0) It uses the newest `syntax-table' property ;-);
724 1) It does 99% of Perl syntax correct (as opposed to 80-90% in Perl
725 mode - but the latter number may have improved too in last years) even
726 with old Emaxen which do not support `syntax-table' property.
728 When using `syntax-table' property for syntax assist hints, it should
729 handle 99.995% of lines correct - or somesuch. It automatically
730 updates syntax assist hints when you edit your script.
734 things tried _all_ the rest of Emacs ;-), but this was not a lonely
735 voice);
737 3) Everything is customizable, one-by-one or in a big sweep;
740 a) Can run program, check syntax, start debugger;
742 a = b;
743 cc = d;
744 c) Can insert spaces where this impoves readability (in one
745 interactive sweep over the buffer);
746 d) Has support for imenu, including:
748 2) Separate TOC of POD sections;
749 3) Separate list of packages;
750 4) Hierarchical view of methods in (sub)packages;
751 5) and functions (by the full name - with package);
752 e) Has an interface to INFO docs for Perl; The interface is
753 very flexible, including shrink-wrapping of
754 documentation buffer/frame;
755 f) Has a builtin list of one-line explanations for perl constructs.
756 g) Can show these explanations if you stay long enough at the
757 corresponding place (or on demand);
758 h) Has an enhanced fontification (using 3 or 4 additional faces
759 comparing to font-lock - basically, different
760 namespaces in Perl have different colors);
761 i) Can construct TAGS basing on its knowledge of Perl syntax,
762 the standard menu has 6 different way to generate
764 bindings - are included in the scan);
765 j) Can build a hierarchical view of classes (via imenu) basing
766 on generated TAGS file;
767 k) Has electric parentheses, electric newlines, uses Abbrev
768 for electric logical constructs
769 while () {}
770 with different styles of expansion (context sensitive
771 to be not so bothering). Electric parentheses behave
774 m) Can convert from
775 if (A) { B }
776 to
777 B if A;
779 n) Highlights (by user-choice) either 3-delimiters constructs
780 (such as tr/a/b/), or regular expressions and `y/tr'.
781 o) Highlights trailing whitespace.
783 5) The indentation engine was very smart, but most of tricks may be
784 not needed anymore with the support for `syntax-table' property. Has
785 progress indicator for indentation (with `imenu' loaded).
787 6) Indent-region improves inline-comments as well; also corrects
788 whitespace *inside* the conditional/loop constructs.
790 7) Fill-paragraph correctly handles multi-line comments;
792 8) Can switch to different indentation styles by one command, and restore
793 the settings present before the switch.
795 9) When doing indentation of control constructs, may correct
796 line-breaks/spacing between elements of the construct.
800 "This is an incomplete compendium of what is available in other parts
801 of CPerl documentation. (Please inform me if I skept anything.)
803 There is a perception that CPerl is slower than alternatives. This part
804 of documentation is designed to overcome this misconception.
806 *By default* CPerl tries to enable the most comfortable settings.
807 From most points of view, correctly working package is infinitely more
808 comfortable than a non-correctly working one, thus by default CPerl
809 prefers correctness over speed. Below is the guide how to change
810 settings if your preferences are different.
812 A) Speed of loading the file. When loading file, CPerl may perform a
813 scan which indicates places which cannot be parsed by primitive Emacs
814 syntax-parsing routines, and marks them up so that either
816 A1) CPerl may work around these deficiencies (for big chunks, mostly
817 PODs and HERE-documents), or
818 A2) On capable Emaxen CPerl will use improved syntax-handlings
819 which reads mark-up hints directly.
821 The scan in case A2 is much more comprehensive, thus may be slower.
823 User can disable syntax-engine-helping scan of A2 by setting
824 `cperl-use-syntax-table-text-property'
825 variable to nil (if it is set to t).
827 One can disable the scan altogether (both A1 and A2) by setting
828 `cperl-pod-here-scan'
829 to nil.
831 B) Speed of editing operations.
833 One can add a (minor) speedup to editing operations by setting
834 `cperl-use-syntax-table-text-property'
835 variable to nil (if it is set to t). This will disable
836 syntax-engine-helping scan, thus will make many more Perl
837 constructs be wrongly recognized by CPerl, thus may lead to
838 wrongly matched parentheses, wrong indentation, etc.
840 One can unset `cperl-syntaxify-unwind'. This might speed up editing
841 of, say, long POD sections.
845 "CPerl mode uses following faces for highlighting:

1241 "Major mode for editing Perl code.
1242 Expression and list commands understand all C brackets.
1243 Tab indents for Perl code.
1244 Paragraphs are separated by blank lines only.
1245 Delete converts tabs to spaces as it moves back.
1247 Various characters in Perl almost always come in pairs: {}, (), [],
1248 sometimes <>. When the user types the first, she gets the second as
1249 well, with optional special formatting done on {}. (Disabled by
1253 whether you want to type pair <>, and inserts is if it
1254 appropriate. You can set `cperl-electric-parens-string' to the string that
1255 contains the parenths from the above list you want to be electrical.
1256 Electricity of parenths is controlled by `cperl-electric-parens'.
1257 You may also set `cperl-electric-parens-mark' to have electric parens
1260 CPerl mode provides expansion of the Perl control constructs:
1262 if, else, elsif, unless, while, until, continue, do,
1263 for, foreach, formy and foreachmy.
1265 and POD directives (Disabled by default, see `cperl-electric-keywords'.)
1267 The user types the keyword immediately followed by a space, which
1268 causes the construct to be expanded, and the point is positioned where
1269 she is most likely to want to be. eg. when the user types a space
1271 } { } and the cursor is between the parentheses. The user can then
1272 type some boolean expression within the parens. Having done that,
1275 directive line, then appropriate number of new lines is inserted).
1279 bite if angry;
1281 it will not do any expansion. See also help on variable
1282 `cperl-extra-newline-before-brace'. (Note that one can switch the
1283 help message on expansion by setting `cperl-message-electric-keyword'
1284 to nil.)
1287 return. It places you in the next line with proper indentation, or if
1288 you type it inside the inline block of control construct, like
1290 foreach (@lines) {print; print}
1292 and you are on a boundary of a statement inside braces, it will
1293 transform the construct into a multiline and will place you into an
1294 appropriately indented blank line. If you need a usual

1313 setting `cperl-electric-keywords' enables electric expansion of
1314 control structures in CPerl. `cperl-electric-linefeed' governs which
1315 one of two linefeed behavior is preferable. You can enable all these
1316 options simultaneously (recommended mode of use) by setting
1317 `cperl-hairy' to t. In this case you can switch separate options off
1318 by setting them to `null'. Note that one may undo the extra

1322 If your site has perl5 documentation in info format, you can use commands
1324 These keys run commands `cperl-info-on-current-command' and
1325 `cperl-info-on-command', which one is which is controlled by variable
1326 `cperl-info-on-command-no-prompt' and `cperl-clobber-lisp-bindings'
1327 \(in turn affected by `cperl-hairy').
1329 Even if you have no info-format documentation, short one-liner-style
1331 man via menu.
1333 It is possible to show this help automatically after some idle time.
1334 This is regulated by variable `cperl-lazy-help-time'. Default with
1335 `cperl-hairy' (if the value of `cperl-lazy-help-time' is nil) is 5
1336 secs idle time . It is also possible to switch this on/off from the
1340 beginning of the region at the start of construction, and make region
1341 span the needed amount of lines.
1343 Variables `cperl-pod-here-scan', `cperl-pod-here-fontify',
1344 `cperl-pod-face', `cperl-pod-head-face' control processing of pod and
1345 here-docs sections. With capable Emaxen results of scan are used
1346 for indentation too, otherwise they are used for highlighting only.
1348 Variables controlling indentation style:
1349 `cperl-tab-always-indent'
1350 Non-nil means TAB in CPerl mode should always reindent the current line,
1351 regardless of where in the line point is when the TAB command is used.
1352 `cperl-indent-left-aligned-comments'
1353 Non-nil means that the comment starting in leftmost column should indent.
1354 `cperl-auto-newline'
1355 Non-nil means automatically newline before and after braces,
1356 and after colons and semicolons, inserted in Perl code. The following
1358 Insertion after colons requires both this variable and
1359 `cperl-auto-newline-after-colon' set.
1360 `cperl-auto-newline-after-colon'
1361 Non-nil means automatically newline even after colons.
1362 Subject to `cperl-auto-newline' setting.
1363 `cperl-indent-level'
1364 Indentation of Perl statements within surrounding block.
1365 The surrounding block's indentation is the indentation
1366 of the line on which the open-brace appears.
1367 `cperl-continued-statement-offset'
1368 Extra indentation given to a substatement, such as the
1369 then-clause of an if, or body of a while, or just a statement continuation.
1370 `cperl-continued-brace-offset'
1371 Extra indentation given to a brace that starts a substatement.
1372 This is in addition to `cperl-continued-statement-offset'.
1373 `cperl-brace-offset'
1374 Extra indentation for line if it starts with an open brace.
1375 `cperl-brace-imaginary-offset'
1376 An open brace following other text is treated as if it the line started
1377 this far to the right of the actual line indentation.
1378 `cperl-label-offset'
1379 Extra indentation for line that is a label.
1380 `cperl-min-label-indent'
1381 Minimal indentation for line that is a label.
1383 Settings for K&R and BSD indentation styles are
1384 `cperl-indent-level' 5 8
1385 `cperl-continued-statement-offset' 5 8
1386 `cperl-brace-offset' -5 -8
1387 `cperl-label-offset' -5 -8
1389 CPerl knows several indentation styles, and may bulk set the
1392 \(both available from menu).
1394 If `cperl-indent-level' is 0, the statement after opening brace in
1395 column 0 is indented on
1396 `cperl-brace-offset'+`cperl-continued-statement-offset'.
1398 Turning on CPerl mode calls the hooks in the variable `cperl-mode-hook'
1399 with no args.
1401 DO NOT FORGET to read micro-docs (available from `Perl' menu)
