2018-02-19FormCalc Assignment is not a SimpleExpressiondan sinclair
Currently the parser builds assignment statements as part of the SimpleExpression declaration. This isn't correct according to the grammar where AssignmentExpression and SimpleExpression are siblings. This CL moves the assignment calculation into the ExpExpression declaration to make it a sibling of the SimpleExpression.

2018-02-19Simplify CXFA_FMToken creationdan sinclair
This CL converts the CXFA_FMToken usages into an object instead of a pointer. A copy constructor has been added. The line number was removed from the token and is retrieved from the lexer where needed.

2017-09-18Convert string class namesRyan Harrison
Automated using git grep & sed. Replace StringC classes with StringView classes. Remove the CFX_ prefix and put string classes in fxcrt namespace. Change AsStringC() to AsStringView(). Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*, Foo). Couple of tests needed to have their names regularlized.

2017-08-16Add parse depth limit to FormCalc parserRyan Harrison
Due to the recursive nature of the FormCalc parser, deeply nested expressions can lead to memory being exhausted. This check is being added to have the parser exit early instead of running out of memory. This should reduce the number of false positives about addressing issues being found by fuzzers.
