Problem with synIDattr()
Christian Brabandt
I recently noticed, that there are some problems with synIDattr()�:
1) the standout highlighting attribute is not mentioned at the help
file or at least not at :h synIDattr()
2) you cannot query the font attribute, although you can set it.
I think this should be possible, since you can set it.
3) synIDattr() returns sometimes incorrect values. Try
gvim -u NONE -c "echo synIDattr(synIDtrans(hlID('Normal')), 'fg',
'cterm')"
This will return -1 though it should probably return an empty string,
I guess.
Attached patch fixes these problems (also available at
http://www.256bit.org/~chrisbra/patches/syIDattr.patch). You can now
query the font attribute using
gvim -u NONE -c "echo synIDattr(synIDtrans(hlID('Normal')), 'font')"
The usual disclaimer applies though: My C-Skills are rusty, so please
review carefully. I have tested this patch and it works for me on
Windows and Linux.
(BTW: could it be possible to have synIDattr() return a dictionary with
all available attributes for a highlighting group? It is very clumsy to
save the hi output without falling back to redir | hi in order to
restore it later.)

Grml, I guess, I just found a bug in my Checkattach plugin
(http://www.vim.org/scripts/script.php?script_id=2796). Well, here is
the patch and the plugin is fixed as well.
