A number of our character helper methods take in wide character types, but only do tests/operations on the ASCII range of characters.

2017-09-06Convert FX_STRSIZE int->size_tRyan Harrison
Change the underlying type for FX_STRSIZE to size_t from int. This will make the value unsigned and thus all values in the range of the type will be valid. This allows for the final remove of negative length strings, but also introduces a some casting and functional errors, since many parts of the code base assume that FX_STRSIZE is int or another signed type. This also CL fixes these errors.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

2017-08-02Rewrite how string Insert() methods handle out of bound indicesRyan Harrison
The existing behaviour was to clamp the provided index to the valid bounds. This would lead to programming errors being hidden, since inserting would still do something even if the index calculation was wrong. The behaviour of these methods has been changed to instead early return when this occurs, returning the old length value. The caller can check if the call to Insert actually did anything by comparing the returned value to the length before calling insert. All of the existing calls to Insert have been tested by running all of the tests with asserts in the Insert method to check the index is in bounds. Additionally the call sites have been manually inspected. The majority of them are of the form Insert(0, foo) and the rest tend to be in a loop advancing from 0 to length. Convenience methods InsertAtFront/InsertAtBack have been added to handle calling Insert when the intent is for the character to be added to the beginning or end of the string. Existing call sites to Insert that do this have been converted. This work was originally being performed to check if there would be any issues in these methods with making FX_STRSIZE unsigned.

2017-08-01Replace raw value for constant error value in string operationsRyan Harrison
Currently Find() and other methods that return a FX_STRSIZE return -1 to indicate error/failure. This means that there is a lot of magic numbers and magic checks floating around. The standard library for similar operations uses a npos constant. This CL implements FX_STRNPOS, and replaces usages of magic number checking. It also does some type cleanup along the way where it was obvious that FX_STRSIZE should be being used. Removing the magic numbers should make eventually changing FX_STRSIZE to be unsigned easier in the future.

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.
