How to highlight 'range different to range?

Hi all,

I have a word which is either a keyword or an attribute the difference between the two case is if the word is preceded by a space it's a keyword, if it is preceded by a ' its an attribute.

Does some one know how to make the syntax highlight to correctly handle this case?

Code: Select all

example:
variable   t : integer range 0 to 127;       -- range is a keyword
variable   s : std_logic_vector(sign'range); -- range is an attribute

Thank's,
Alain

A really not perfect solution would be to highlight 'range with a marker character specification:

/Marker Characters = "'e"
/C1"keywords"
range
/C2"attributes"
'e

But this would work only if the ' character is used only for 'range and nothing else in the whole file.

The problem here is that there is no other delimiter between sign and 'range. So the ' must be also a delimiter and this makes it impossible to specify 'range as a highlighting "word".
