2017-07-28Convert calls to Mid() to Left() or Right() if possibleRyan Harrison
The various string/byte classes support Mid(), Left(), and Right() for extracting substrings. Mid() can handle all possible cases, but Left() and Right() are useful for common cases and more explicit about what is going on. Calls like Mid(offset, length - offset) can be converted to Right(length - offset). Calls like Mid(0, length) can be converted to Left(length). If the substring being extracted does not extend all the way to one of the edges of the string, then Mid() still needs to be used.

2017-07-27Remove single param Mid() method from string classesRyan Harrison
This support is being removed from CFX_ByteString, CFX_ByteStringC, CFX_WideString, and CFX_WideStringC. This standardizes all of these classes to only have one Mid method that takes in 2 params, offset and count. Count now must be positive. The old behaviour of calculating the length for the user if -1 is passed in for the count has been removed. This work is in preperation for converting these classes to not accept negative lengths anywhere and thus make the underlying size type unsigned.

2017-07-27Rewrite FMLexer to use nullptr for errorsRyan Harrison
This CL rewrites how FMLexer returns errors, instead of having a flag that gets flipped and needs to be checked, it now returns nullptr for NextToken() when an error occurs. The Lexer's behaviour has also been changed to only return nullptr once an error has occurred, instead of advancing the lexing on further calls. FMParse now checks the returned value from the lexer instead of testing the error flag on the parser object. For any operation that might cause the error state of the parser to change, i.e. consuming a token, an error check has been added. In the event this check fails the related function returns nullptr. This will cause the parse to short circuit and exit.

2017-07-24Remove extracting characters from inputRyan Harrison
Throughout the lexer there is use of a pattern where a character is extracted from the location currently being pointed at in the input and tests are done on this value. This is uneeded, since normally the pointer isn't being modified while the character is stored, so the pointer can be dereferenced directly. This CL also cleans ups the implementation of string extraction from the input to be easier to read, since it did depend on the character being extracted to work. The IsFooCharacter methods are also changed to take in a character instead of a pointer, since they are only testing the character value not the pointer.
