I am using "glasses-mode", but  It is difficult to distinguish which words get changed. For instance, if one has a mixture of CamelCase, Under_scores one would not know which is modified and which is original. Particularly problematic when one is modifying the code.

Could "glasses-mode" be made in such way as to indicate that "glasses-mode" changed its display, by default.

I think we have this already: customize glasses-face to some distinct
face, like 'bold'.  Then the capital letters of identifiers where
glasses.el inserted underscores will be shown in bold, and you can
visually distinguish them from the original underscores.

Also, I think the idea with this mode is to use it in languages where
camelCase is the accepted way to write things -- and they never mix
camelCase with camel_Case, so changing the defaults here would also be
inappropriate.

So I don't think there's anything here to be fixed, and I'm closing this
bug report.

Because I use bold font the default does not work for me.  I want to
make the changes in my init file.  How can I change the foreground
and background colour of the glasses matches?  Is it possible for users
to use a UTF8 Code as separator, and if so, how can this be done?

Being able to use unicode for separator would be valuable as the typeface
can remain the same, whilst the separator would clearly indicate that the
symbol used is not part of the original code.

??? What default?  The default is that glasses-face is just nil, so no
special face is put on any parts of the identifiers.  'bold' was just
an example of a non-default face; you can use any face there.

You can't.  This face is not about changing the matches, it is about
changing the appearance of the capital letters in identifiers where
glasses-mode adds the separator (which is underscore _ by default)

Customize the variable glasses-separator.  (This has nothing to do
with the original bug report, though.)

How can I change the colour of the capital letters or use utf8 using
elisp commands?

You could just do 

(setq glasses-separator "➾")

with the character being a utf8 symbol.

I would prefer using utf symbols than changing colours.

I am using the following function using hex code for Black Rightwards Arrowhead

(defun typex-camelsens ()

  "Splits CamelCase phrases using separator."

  (interactive)

  (setq glasses-separator "\u27A4")

  (glasses-mode))

How can I pass an arbitrary hex code interactively, besides using a default?

No, that will not work in general in this case.  You must use
Customize.

Been focusing on getting this to work

(defun camelsens (hexcode)

  "Splits CamelCase phrases using separator."

  (interactive (list 

      (completing-read "Utf8_hex_code: " '("\u27A4" "\u25BA" "\u2192") nil t "\u2192")))

  (setq glasses-separator hexcode)

  (glasses-mode))

But this only works the first time I call the function.

You cannot simply assign the value to this variable.  Look at its
defcustom form to understand what is missing.

And anyway, what does this have to do with the bug report?  You are
asking basic Emacs Lisp questions.

Because I can use utf, I can easily distinguish between code and glasses display.
This feature solves my problem.

So do use it.  It is possible and supported, just not by a simple
setq.

Here's the defcustom of that option from glasses.el:

  (defcustom glasses-separator "_"
    "String to be displayed as a visual separator in identifiers.
  It is used both for adding missing separators and for replacing separators
  defined by `glasses-original-separator'.  If you don't want to add missing
  separators, set `glasses-separator' to an empty string.  If you don't want to
  replace existent separators, set `glasses-original-separator' to an empty
  string."
    :type 'string
    :set 'glasses-custom-set
    :initialize 'custom-initialize-default)

What does the :set attribute tell you?

I could call (glasses-set-overlay-properties)

That's not really related.

What the :set attribute says is that you need to call that function
after changing the value, to "install" the new value.

The function "glasses-custom-set"?  The documentation also states that
"glasses-set-overlay-properties" can also be used.  What would be the 
best code sequence then?
