The default value of this variable is "^#". - -** Changes to Rmail mode - -*** The new user-option rmail-user-mail-address-regexp can be -set to fine tune the identification of the correspondent when -receiving new mail.

For example, some people like -to have the filename and date on separate lines. The new variable -time-stamp-inserts-lines controls the matching for multi-line patterns. - -*** More than one time stamp can be updated in the same file. This -feature is useful if you need separate time stamps in a program source -file to both include in formatted documentation and insert in the -compiled binary.

All other matches are +highlighted using face `isearch-lazy-highlight-face' which defaults to +`secondary-selection'. + +The extra highlighting makes it easier to anticipate where the cursor +will end up each time you press C-s or C-r to repeat a pending search. +Highlighting of these additional matches happens in a deferred fashion +using "idle timers," so the cycles needed do not rob isearch of its +usual snappy response. + +If `isearch-lazy-highlight-cleanup' is set to t, highlights for +matches are automatically cleared when you end the search.

It is now +possible to bind a regexp to a language, by prepending the regexp with +{lang}, where lang is one of the languages that `etags --help' prints out. +This feature is useful especially for regex files, where each line contains +a regular expression. The manual contains details. + +*** In C and derived languages, etags creates tags for function +declarations when given the --declarations option. + +*** In C++, tags are created for "operator". The tags have the form +"operator+", without spaces between the keyword and the operator. + +*** You shouldn't generally need any more the -C or -c++ option: etags +automatically switches to C++ parsing when it meets the `class' or +`template' keywords. + +*** Etags now is able to delve at arbitrary deeps into nested structures in +C-like languages. Previously, it was limited to one or two brace levels. + +*** New language Ada: tags are functions, procedures, packages, tasks, and +types. + +*** In Fortran, `procedure' is not tagged. + +*** In Java, tags are created for "interface". + +*** In Lisp, "(defstruct (foo", "(defun (operator" and similar constructs +are now tagged. + +*** In makefiles, tags the targets. + +*** In Perl, the --globals option tags global variables. my and local +variables are tagged. + +*** New language Python: def and class at the beginning of a line are tags. + +*** .ss files are Scheme files, .pdb is Postscript with C syntax, .psw is +for PSWrap. + ++++ +** Changes in etags.el + +*** The new user-option tags-case-fold-search can be used to make +tags operations case-sensitive or case-insensitive. The default +is to use the same setting as case-fold-search. + +*** You can display additional output with M-x tags-apropos by setting +the new variable tags-apropos-additional-actions. + +If non-nil, the variable's value should be a list of triples (TITLE +FUNCTION TO-SEARCH).

If it is a symbol, the symbol's value is used. + +TITLE is a string to use to label the list of tags from TO-SEARCH. + +FUNCTION is a function to call when an entry is selected in the Tags +List buffer. It is called with one argument, the selected symbol. + +A useful example value for this variable might be something like: + + '(("Emacs Lisp" Info-goto-emacs-command-node obarray) + ("Common Lisp" common-lisp-hyperspec common-lisp-hyperspec-obarray) + ("SCWM" scwm-documentation scwm-obarray)) + +*** The face tags-tag-face can be used to customize the appearance +of tags in the output of M-x tags-apropos. + +*** Setting tags-apropos-verbose to a non-nil value displays the +names of tags files in the *Tags List* buffer. + +*** You can now search for tags that are part of the filename itself. +If you have tagged the files topfile.c subdir/subfile.c +/tmp/tempfile.c, you can now search for tags "topfile.c", "subfile.c", +"dir/sub", "tempfile", "tempfile.c". If the tag matches the file name, +point will go to the beginning of the file. + +*** Compressed files are now transparently supported if +auto-compression-mode is active.
