Thanks for your help, I had another look and found out you need another syntax
command to reproduce it properly. Here is the revised bug report
Start vim using
vim -u NONE
insert the following test code (note that the 4th line must be indented).
array($foo)
is_array $foo
is_array($foo)
is_array($foo)
Apply the following syntax commands:
syn on
syn keyword Function is_array
syn region r1 matchgroup=Type start=/array(/ end=/)/
syn keyword Error foo containedin=NOTHING
You will find that the keyword is_array and region r1 are confused over how to
highlight is_array(...) when it doesn't start at the beginning of the line, and
it has something to do with the 'foo' keyword having a 'containedin=' option.
regards,
Peter
