RE: [cdt-dev] add new keyword recognize by the dom parser
|
Hi Christian,
the additional keywords are considered after the preprocessor computes
the steam of tokens. You can use additional keywords to map
identifier-tokens to other tokens. The '@' character is not an
identifier, therefore the mapping does not work.
As a solution we can provide an option for the preprocessor to allow '@'
as part of identifiers (similar to how we deal with '$', which is
accepted by gcc).
Please create an enhancement request on bugzilla.
Markus.
