making curly apostrophe part of a word

making curly apostrophe part of a word

[Eric Abrahamsen]

In certain modes (actually just certain files) I'd like the `’'
character to be treated the same as a `'' character with respect to word
movement: ie I'd like M-f to skip over the entirety of both "don't" and
"don’t". I'm editing externally-created files, and don't have the
liberty of changing this.

I thought this would do it:

(modify-syntax-entry ?’ "w")

To give the quote character word syntax, but word-level commands still
treat it as a word boundary. Looking at describe-syntax, it appears to
have the same status as regular old `'' (apart from the "p" flag, which
I don't think is relevant). What am I doing wrong?

Thanks!
E

Works for me in current buffer. `forward-word' passes as expected.
Which command fails for you?

`forward-word' fails... Hang on, I'll do the emacs -Q dance and see
what's going on. This was originally in an html-mode buffer, but I don't
see why that would matter as long as no third argument was passed to
`modify-syntax-entry'.

Thanks,
E

It affects the current buffer only, not the mode in other buffers when done that way - maybe that's it?

Not according to its doc string:

	The syntax is changed only for table SYNTAX-TABLE, which defaults to
	 the current buffer's syntax table.

Different buffers in the same major mode usually share the same syntax table.

Ugh, this is very weird. I started emacs -Q (emacs-version "24.3.1"),
went into an empty buffer and turned it into text mode, then put in
these lines:

can’t

bug&bear

bug©bear

All three of "’", "&", and "©" originally act as word boundaries:
invoking M-f from the front of the word and M-b from the back stops once
_before_ the symbol. The next invocation goes to the next whitespace.

Then for each of those three symbols I call (modify-syntax-entry ?[char]
"w"). Now "&" and "©" behave as expected: M-f and M-b jump all the way
across.

But "’" is different: after modifying its syntax, word-movement commands
stop _twice_, once on each side of the character, before moving to the
other end of the word.

I wonder if I've somehow added "w" to its existing syntax definition,
without "clearing" the existing definition, and that's why it's behaving
strangely?

No idea,
E
