Whenever a Lexer_Error or Parser_Error is raised it is always accompanied + with a string that contains encoded information about where in the input the error occurred.

+ +

Such strings should not be examined directly, but if the Decode function from + Packrat.Errors is used then an array of symbol/position pairs is obtained. Each of those + pairs describes a point in the input where, if the given symbol was successfully found, a more + successful parse would have resulted.

+ +

Unfortunately at this time no resumption of lexing or parsing can be done once an error has + occurred.
