feat: support a `--trace` or `--debug` flag #11

Closed osterman closed 4 years ago

osterman commented 4 years ago

what

provide a way to trace the execution of a pipeline with verbose output of what's being run and the values of options and parameters (perhaps mask secrets?)

use-case

The more complicated the executions, the harder it is to debug what's going on
Perhaps it would be also helpful to be able to step through the execution (but this is not immediately a requirement for me)

@osterman Hey! Thanks for this - Please read https://github.com/mumoshu/variant2#debugging-commands to see how it works. I've chosen the envvar to enable tracing, so that we don't pollute user defined variant run flags.

Make sense. Thanks!!
