This is a sample of the colouring which is provided by the "darkbone.vim" colour scheme (updated):

sample

On the "TMP=" line, the "${ }" delimiters are different from the "TMP" variable name. That is something I want to replicate in another colour scheme file.

However, I am unable to identify the Class which controls the delimiters separately from the variable itself (which I have identified as "PreProc").

Comparing different files, I found that "Delimiter" was not included in darkbone.vim, so I added that, specifying guifg=#FF0000 , but there was no identifiable change to my fullscreen display of the test file, where both the delimiters and the "called" variable name have the same colour.

Anyone have insights into how to control that for the delimiters ?

The 'scriptnames' report is as follows:

If it can make things easier, here is my draft colorscheme file:

Reset to default

Syntax highlighting is done in two steps:

  1. highlight groups are defined with regular expressions in a "syntax script" and often linked to more generic ones,
  2. visual attributes are assigned to highlight groups in a colorscheme.

The most immediate consequence of this is that the colorscheme can't highlight non-existing highlight groups.

Which leads to our next problem: as per the default syntax script for the sh filetype…

  • ${ belongs to the shDeref and PreProc groups,
  • TMP belongs to shDeref and shDerefVar,
  • } belongs to PreProc,
  • they all resolve to the PreProc highlight group.

meaning that your colorscheme in its current form and the default syntax script for sh make it impossible to highlight ${} and TMP differently.

Here is how the two first lines of your script look with darkbone.vim and the default syntax script for sh:

sh

And here is your screenshot:

op

You will notice that there are quite a few discrepancies.

So, if your colorscheme and the default syntax script both consider ${TMP} as a single "block" belonging to the PreProc highlight group, then you might be using a third-party syntax script that thinks otherwise.

Furthermore, the only highlight group highlighted in orange in your colorscheme is Function so there is definitely something, somewhere, that overrides the default highlight groups in one way or another.

FWIW, you can use the following command to identify the highlight group(s) of the item under your cursor:

command! SynStack echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')

I tried that command you provided at the bottom, both with the "command! " prefix and without it, and I get no perceivable action for the first, and the error msg "E488: Trailing characters" for the latter.
I have suppressed the copy of bash.vim and sh.vim which I had made from my ~/.vim/syntax. I still get the same result.
Copying and executing.
Thank you, Romaini. That is a very useful snippet. I will let you know when I resolve my issue.
So ... apparently, when cycling thru the various colorscheme files using ScrollColors, vim.org/scripts/script.php?script_id=1488, it became apparent that there is not a full reset between Colour Scheme files being used for display (even though) the files do have the reset line in them at the start! So ... some syntax classes were inhereting colours defined in previous schemes, and applying those! Very confusing. The fact that such dual colour combinations show for ${TMP} implies there must be a way to control it. I will continue my search by trial and error.
