replacing two consecutive words where the two words could be separated by multiple spaces or newlines.

replacing two consecutive words where the two words could be separated by multiple spaces or newlines.

[Nobuko Three]

I wanted to replace all occurrences of `a integer' with `an integer' in a
latex file. But a simple query replace would replace the first `a integer'
of the following paragraph, but not the second one because the second one is
actually separated by a newline and two spaces (the indent).


  This is a integer. That is a
  integer. ...

What is an automated way to change paragraphs like above to paragraphs like
below?

  This is an integer. That is an
  integer. ...

You can do this using regular expressions:

M-x replace-regexp RET a\(\s-+\)integer RET an\1integer RET

I was curious about the "\s-" because I've never seen such a thing.
It sort of makes sense after RTFM, but it doesn't work all the time.
Is it equivalent to "[[:space:]]"?  Apparently, it depends on the
major mode.

"a\([[:space:]^J]+\)integer" works for me, where "^J" is C-q C-j.

Of course :-)

I think that newline has comment-ender syntax (not whitespace-character)
in some major modes.
