If I use the matchadd function to highlight a region

Or, can synIDattr only be used with ids associated with
syntax groups?
I tried and 1) it returned different values on subsequent
runs and 2) I have a 256 color term but it returns only
values between 0 and 15.
Thanks

synIDattr() needs as its first argument a syntax ID. matchadd() gives
you a match ID. They are not the same and cannot be used
interchangeably. The recommended way to obtain a synID to be plugged
into synIDattr() is by using the synID() function, optionally converted
by synIDtrans(). Or you could use the List output of synstack() and
extract the synIDs from it by means of a little fancy footwork.
You have a 256-color term but have you got a 256-color colorscheme and a
Vim that knows about it? In a GUI-enabled Vim for Linux running in
console mode in a 256-color xterm with the CSApprox plugin, I get fg=201
bg=-1 for the helpHyperTextEntry group.
I used the following to determine values at the cursor:
:echomsg "fg=" . synIDattr(synIDtrans(synID(line("."), col("."), 0)),
"fg", "cterm") "bg=" . synIDattr(synIDtrans(synID(line("."), col("."),
0)), "bg", "cterm")
It is one single long ex-command.
Best regards,
Tony.
