[DEBUG:] Error loading output file, err: InvalidJSONInput: parse error: premature EOF #36

Open cizra opened 5 months ago

When rebuilding a project that's open in Mudlet, Mudlet shows this error message:

[DEBUG:] Error loading output file, err: InvalidJSONInput: parse error: premature EOF

                     (right here) ------^

I suspect this is probably caused by muddler writing directly into .output. This truncates the file, which Mudlets reacts on, before adding the new content.

To make this process atomic, create a new temporary file somewhere in the same directory (or at least filesystem), then rename the temp file into .output, overwriting the original.
