Fwd: Vim syntax (variables)

[D. Ben Knoble]

All,

I sent the following message to Dr. Chip RE: vim syntax files, and it
bounced back; do we know if there's a more current contact for him
(and whether or not he's ok)?

Chip,

I've got a suggestion for the vim syntax files that you maintain.
(I'll attach a patch.)

There are a couple of places I've spotted where certain kinds of
variables, namely environment variables of the form $PATH or ${PATH},
are not highlighted—and yet in others, they are.

The following patch *seems* to enable highlighting after the :let and
:if keywords; let me know what you think.

Best,
D. Ben Knoble

Hello:

I don't know how my old (as in no longer active) email address remained
in syntax/vim.vim, because I updated all of the syntax files with my new
address. I just sent an updated syntax/vim.vim to Bram  with the correct
email address. Just look at any of the other syntax files I maintain
(tex.vim, etc) and you'll get the correct email address.

That said, your attachment looks pretty short -- I'll look it over,
apply it, and run it through my test files.

Thanks for correcting the email (I searched your site for ages trying
to find a different one, but didn't look in the other vim files).

I'll grant your example highlights according to my expectations, but
this one doesn't (in either the :if or the :let):

function F()
if $HOME =~ "^/home"
echo "GOT HERE#1"
else
echo "GOT HERE#2"
endif
let $HOME = "/some/home"
endfunction

It seems the function body impedes the other rules (??).

Best,
