-
-Most of the time, if you write your own code, you may find an equivalent
-\(and almost as readable) expression (what is discussed below is usually
-not relevant on newer Emacsen, since they can do it automatically).
-
-Try to help CPerl: add comments with embedded quotes to fix CPerl
-misunderstandings about the end of quotation:
-
-$a='500$'; # ';
-
-You won't need it too often. The reason: $ \"quotes\" the following
-character (this saves a life a lot of times in CPerl), thus due to
-Emacs parsing rules it does not consider tick (i.e., ' ) after a
-dollar as a closing one, but as a usual character. This is usually
-correct, but not in the above context.
-
-Even with older Emacsen the indentation code is pretty wise. The only
-drawback is that it relied on Emacs parsing to find matching
-parentheses. And Emacs *could not* match parentheses in Perl 100%
-correctly. So
- 1 if s#//#/#;
-would not break indentation, but
- 1 if ( s#//#/# );
-would. Upgrade.
-
-By similar reasons
- s\"abc\"def\";
-could confuse CPerl a lot.
-
-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).
-
-Pods were treated _very_ rudimentally. Here-documents were not
-treated at all (except highlighting and inhibiting indentation). Upgrade.
-
-To speed up coloring the following compromises exist:
- a) sub in $mypackage::sub may be highlighted.
- b) -z in [a-z] may be highlighted.
- c) if your regexp contains a keyword (like \"s\"), it may be highlighted.
-
-
-Imenu in 19.31 is broken. Set `imenu-use-keymap-menu' to t, and remove
-`car' before `imenu-choose-buffer-index' in `imenu'.
-`imenu-add-to-menubar' in 20.2 is broken.
