I just need the exact word. Dear Web, The following should do the trick, searching for the word "machine" either at the beginning of a line and followed by a space, surrounded by spaces, or preceded by a space and at the end of a line. Type the following (not the bit with the dashes, though): -----------------|CODE|----------------- M-x re-search-forward RET \(^\|[ \t]\)machine\([ \t]\|$\) ---------------------------------------- It's probably more constructive to copy the regexp than to type it all in. This will place your cursor at the *end* of whatever it finds. For more information, the section in the Info system on regexps is useful.

I just need the exact word. Assuming that "ret" means hit the Enter key (usually written RET), that should work fine (assuming you also follow it by another RET). It should not find "Machine" in the middle of other words; it should find it only as a whole word. It is a non-incremental search, however, which is usually less convenient than incremental search. > You want either M-C-s \ b M a c h i n e \ b That's incremental and works fine, but can be a bit hard to remember. > or perhaps M-x word-search-forward RET Machine RET Aother way to do incremental word search (also a bit hard to remember): C-s M-e C-w M a c h i n e C-s Starting with Emacs 22, this is documented in the Emacs manual (node Word Search). Another way, if you use Isearch+ (http://www.emacswiki.org/cgi-bin/wiki/IsearchPlus): C-s M-w M a c h i n e This (`isearch-toggle-word') is from Juri Linkov, BTW. I thought it was going to be added to Emacs a year ago, but it looks like it never was. Too bad. An advantage is that `M-w' is a toggle between word and non-word search - use it at any time. ^ permalink raw reply [flat|nested] 9+ messages in thread

I just need the exact word. `running_machine_state' usually counts as a symbol consisting of three words.

However, i don't think it as a practical, necessary, book, for average professional programers who works with text a lot (such as web app developers and sys admins). Because: * in my extensive use of regexes, daily, since about 1998 working in the web application industry and sys admin, i only need to use advanced regex maybe once or twice a year. * most complex regexes needs, are more practical to be implemented by breaking down into 2 patterns to test on (as opposed to a single complex regex). * when you need advanced regexes, the regex very quickly cannot handle the job. You need either to break it into several regexes with nested if statements, or you need a parser. in the above, by "advanced regexes" i mean non-grouping constructs of the form (?...), boundary anchors, nested patterns... etc. ------------------- related articles i've wrote: * Pyhton Regex Documentation: String Pattern Matching (complete rewrite of python's re module doc.) http://xahlee.org/perl-python/python_re-write/lib/module-re.html * Simple intro to emacs's regex http://xahlee.org/emacs/emacs_regex.html * Emacs Lisp regex doc http://xahlee.org/elisp/Regular-Expressions.html Xah xah@xahlee.org \xAD\xF4 http://xahlee.org/ > To convince her and others to get it, how about > some comments from those who've got the book?
