Hi,
first of all, please excuse this cross-post. I tried to get an answer on the instaparse list first, but it does not seem to reach so many instaparse users. Unfortunately I do not know the correct name for the problem I face, hence the rather vague subject. I am trying to parse a file format with Instaparse in which the early parts define the stuff allowed later in the file. E.g. here is a declaration of allowed symbols: # single chars or strings symbols: a b c "str" Later, the file contains declarations of enumerations of the form enum-name: list of allowed values separated by whitespace Further down in the file, I will find strings which are comprised of the symbols declared above, e.g. "aabcbc&str;a" and I will see structures that use the enumerations StructName(enum-name=separated) How would you approach this? * Write a very loose grammar which accepts basically all unicode chars in the symbol strings and validate in a separate step? Similarly accept all values in the structures and later validate against the enumerations? * Two pass parsing which first reads the declarative stuff and then builds a second grammar programmatically to parse the rest? * Is there a way to fill tables of allowed symbols during the parsing? * Something completely different? With that question out of the way, thanks for instaparse which is a pleasure to use while I am converting my 1400 LOClojureCode hand-rolled parser.
