I was trying to loop over parent directories to find cscope.out files.
And I don't quite grok the following:
Why does this print 'blah':
:let file = "blah" | echo file
while this complains that 'file' isn't found:
:let file = "blah" | cs add file
Just like with LISP, there's something about Vim
quoting/expressions/interpolation that doesn't quite match up with my
expectations.
As a workaround cobbled together from bits and pieces, I'm doing:
let s:cscope_name = "whatever"
" ...
exec "sil! cs add ".s:cscope_name
But, my main worry is that something isn't right w/ the concatenation
there.
E.g: (I think this doesn't work, but hopefully demonstrates my general concern)
let s:var = "blah | system(do-something-malicious)"
exec "sil! cs add ".s:var
Best,
Ben
