`\0` in strings. #192

Is there a particular reason \n gets treated differently? I was hit by this while testing the simple dynamic string library wrapper in ATS, source code. The literal string emitted by ATS is incorrect.

It is for handling multi-line strings. What literal string emitted by ATS is incorrect?

steinwaywhw commented 6 years ago

Oh my bad. It is \0 that is treated incorrectly. "\a\n\0foo\r" is emitted as ATSPMVstring("\007\n")

githwxi commented 6 years ago

A string in ATS cannot contain '\0' in the middle.

steinwaywhw commented 6 years ago

Ok, I see. Maybe in the future we can add support for \0. Low priority.
