Position Combinators (parsley.position)
During a parse, position information is tracked and recorded by parsley.
The parsley.position module contains combinators that can access this
information so that it can be used in the construction of the results.
The Scaladoc for this page can be found at parsley.position.
Position Extraction
The line and col parsers will extract the line and column respectively. In
parsley, the first line and column are both 1. For convenience, the pos
parser is defined as line.zip(col).
Offset Extraction
The offset parser can be used to obtain the raw underlying offset of
a parser, which can be used for calculations on the number of characters (not codepoints) a parser consumes, but should not be used to derive positions themselves.
