ARGS:
    <INPUT>    The input file

    -h, --help                         Print help information
    -i, --indentation <INDENTATION>    The indentation, s will replaced by a space and t by a tab.

Reads from stdin if no file is supplied. Outputs to stdout if no output file is specified.

Error handling

jsonformat does not report malformed json - it can't even fully know whether the json is actually malformed. Malformed json is just formatted kind of incorrectly, with no data lost and no crashes. If you find one, open an issue,

How?

jsonformat does not actually parse the json, it just loops through each character and keeps track of some flags. It then copies these characters to the output buffer, adding and removing whitespace.

No runtime deps
