2018-08-17Rename CJS_Return to CJS_Result.Tom Sepez
"Return" is a verb, and "return" is a reserved-word at that, so avoid using it as part of a class name. Fully mechanical change apart from rename.

2018-08-08Move ByteString::FromUnicode() to WideString::ToDefANSI()Tom Sepez
Turns out that "FromUnicode" is misleading in that, on linux, it simply removes any characters beyond 0xFF and passes the rest unchanged, so no unicode decoding actually takes place. On Windows, it passes it into the system function specifying FX_CODEPAGE_DefANSI, converting it into the so-called "default ANSI code plane", passing some characters, converting others to '?' and still others to 'A'. Either way, nothing resembling UTF8 comes out of this, so pick a better name. These now immediately look suspicious, so a follow-up CL will see which ones should really be WideString::UTF8Encode() instead. Making this a normal method on a widestring rather than a static method on a bytestring feels more natural; this is parallel to the UTF8Encode and UTF16LE_Encode functions. Add a test that shows these conversions.

2018-06-21Clean up constant values for JS alert and beepRyan Harrison
Define constant values in the public API for the valid values of alert button type, alert icon type, and beep type. Replace various magic numbers through out the code base using these values. Also replace the XFA specific versions with an enum class that is guaranteed to have the same values, instead of #defines that just happen to. This CL does not attempt to add error checking on these values, since it currently doesn't exist so adding it may cause regressions.

2018-06-21Remove WideString::c_str() calls where possible.Tom Sepez

2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().
