Errors when calling one print-data method from another. #17
Description
Hi Kanru,
first of all thanks for the library!
When I incorrectly created the mustache environment using something like '((key value)) instead of '((key . value)), I was hit by an error that the escape flag for {{{...}}} had not been correctly evaluated, means that even for the triple-pattern, escape was called.
It turned out that the incorrect environment did lead to the call of '(defmethod print-data (token escapep &optional context) ...)' and that this method forwarded processing to another print-data method with incorrect arguments: instead of calling '(print-data (princ-to-string token) (%output))' I think it's necessary to call '(print-data (princ-to-string token) escapep context)'. The incorrect call passed the stream %output as escape a non-nil flag, so that escape was always called, whereas the proposed fixed won't do this. (Also the context argument was missing.)
While searching, I also found that also '(defmethod print-data ((data symbol) escapep &optional context) ...)' does not pass the context parameter and I think it is necessary to change the body to '(print-data (string data) escapep context)'.
HTH and best regards, Frank
