Examples (TL;DR)


nop [ -p? ] [ files ]


nop reads a stream of graphs and prints each in pretty-printed (canonical) format on stdout. If no files are given, it reads from stdin.


The following options are supported:


Produce no output - just check the input for valid DOT.


Print usage information.

Exit Status

If any errors occurred while processing any input, such as a file not found or a file containing illegal DOT, EXIT_FAILURE is returned. Otherwise EXIT_SUCCESS is returned.
