Hi all,
I've reported the same thing a few years ago, it got fixed pretty fast
but looks like it reverted again.

First ensure font-lock mode is on. Prefix arg forces it on.

   C-u 1 M-x font-lock-mode

Minibuffer says font lock mode is enabled

type some text to be highlighted:

  peq
  piq

highlight regexp:

  M-s h r  p[aeiou]q

the above 2 get highlighted as expected

now type some matchable text

  paq

this does not get highlighted.
I expected it should and as I've used this functionality extensively
before, I'm pretty sure it used to work this way.

regards

jan

Further, editing the existing highlighted expressions such that they
no longer match the regexp does not un-highlight them

I cannot reproduce this.

What was the major mode in the buffer where you tried this?  I'm
asking because font-lock-mode is turned on by default, so I don't
understand why you needed to turn it on.  E.g., try repeating the
sequence, without the font-lock-mode command, in *scratch* as soon as
you enter "emacs -Q".

Can't reproduce this, either.

That other buffer is in Fundamental mode, right?  Font-lock does
nothing in Fundamental mode.

Hi,
I don't know much about modes, I'm an emacs user rather than an emacs
programmer. So yep, it was fundamental. I'll do some reading on modes
tonight.

But FWIW I found this originally happening in another mode where I was
trying to identify large chunks easily.
So while this is surely my mistake also, to reproduce, I dragged a.txt
file from a git repo into emacs (again, windows - started with emacs
-Q to be sure)

It said 'git-master' in the status bar.

M-x describe-mode gives

Enabled minor modes: Auto-Composition Auto-Compression Auto-Encryption
Blink-Cursor Diff-Auto-Refine Electric-Indent File-Name-Shadow
Font-Lock Global-Eldoc Global-Font-Lock Line-Number Menu-Bar
Mouse-Wheel Tool-Bar Tooltip Transient-Mark

I can reproduce my 'wrong' behaviour in this text file. I wasn't expecting that.

So FYI and this is surely just my misunderstanding, sorry for messing
you around.

jan

Which mode was that?

These are minor modes.  The font-lock operation is determined by the
major mode.  You can tell what major mode is active in a buffer with
this:

  M-: major-mode RET

@jan: The test that hi-lock uses internally is actually

  (and font-lock-mode (font-lock-specified-p major-mode))

so you need an implemented font-locking in your buffer.  I guess this is
intentional and has its reasons.  But yes, it is surprising.

@Eli: the docstring of `hi-lock-mode' just says:

"In buffers where Font Lock mode is enabled, patterns are
highlighted using font lock."

That's wrong, I think the docstring should be adapted.  _Or_
hi-lock-mode could query the user whether he still wants to enable
hi-locking using font-lock, with the risk of messing up other
highlighting that doesn't come from font-lock.

Michael.

Doing as you say (M-: major-mode RET) it says it is in text-mode.

Which I think is the same as Fundamental mode wrt font-lock.

You need to be in a major mode that defines font-lock settings.

I don't understand this reply as I'm very much an emacs user not an
emacs programmer, but "...could query the user whether he still wants
to enable hi-locking using font-lock, with the risk of messing up..."
 - this kind of thing, letting me know I can't have what I'm asking
for (or can but at a risk) would be helpful so I know I'm not going to
get it.
I reported this as a bug out of ignorance, some hint from emacs that
it was PEBKAC[0] would have saved me wasting Eli's time.

"is implemented and enabled" maybe?  We could also say that Font Lock
mode must be enabled and the MODE must fulfill `font-lock-specified-p'.
Or a combination of those words.

What I wanted to say was that your report was totally justified because
what the docstring tells about font-lock mode is a bit misleading.

Maybe hi-lock could also tell you which method of highlighting it
chooses.  And maybe it would also make sense to allow using the
font-lock mode based method in modes that don't implemented font-lock,
I'm not sure.

Michael.

Skimming this bug report, it seems like this doc fix was all that's
required, so I'm closing this bug report now.
