search for any two consecutive uppercase characters

search for any two consecutive uppercase characters

Hello all:

Is there a way to search for any two consecutive uppercase characters? In example "PÉREZ" or "GONZÁLEZ"

I was looking in the manuals but I didn´t find it.

I want to make a macro that looks for a word all uppercase, go to the beggining of that word and Capitalize it. Unsing the words in the example: "Pérez" or "González".

Thankyou in advance.

Yes, this is difficult, because of the accented letters.  There is no
[:upper:] in emacs regular expressions.  It might be possible to build
a syntax table or something to identify uppercase letters including
accented ones, but AFAIK, there's nothing built in.  The simpliest
would be to prepare a regular expression explicitely listing all the
characters you'd want, something like:

          "\\<[A-ZÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞ]+\\>"

but in all generality, you'd miss a lot of other capital letters.

That's easier to do.  Just beware of the triple negation ;-)


(require 'cl)

(defun capitalize-uppercase-words (start end)
  (interactive "r")
  (goto-char start)
  (while (re-search-forward "\\<\\sw*\\>"  end t)
    (let ((word  (match-string 0))
          (start (match-beginning 0))
          (end   (match-end 0)))
      (unless (some (lambda (ch) (char/= ch (upcase ch))) word)
        (delete-region start end)
        (insert (capitalize word))))))

That' actually not true, as described here

Isn't
C-u C-s   (aka isearch-forward-regexp)
[A-ZÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞ]\{2,\}
better?

here \{2,\}
means two (or more) of the preceding expression.

FSVO "better".

They don't mean the same.
My expression means: words containing only uppercase letters.
Your expression means: any occurence of two or more consecutive uppercase letters.

Is 0x42AB   a word?  (I'd say no, it's a number in C syntax for hexadecimal).
Is NeXTstep a word?  (Yes, but it's not all uppercase).

Hello:

Thankyou very much for yours answers.

Please excuse my ignorance but I dont know exactly how tu use the code.

I paste it in my .emacs file. To use I type M-x "capitalize-uppercase-words"

then appears a mesage: "The mark is not set now, so there is no region".

What shoul I do?

Thanks again

Mark the area in which you want to change the case of letters!

Depends on what you want.  You could modify the command so that it can
work without a region selected, or you could select a region to be
processed by capitalize-uppercase-words.

Yes, [:upper:] is available. A common error is using it directly.
Indeed, it must be put in a char class like [[:upper:]].

The problem can be solved using query-replace-regexp

Search Pattern: \<[[:upper:]]\{2,\}\>
Replace:  \,(capitalize \&)
