Subject: [notmuch] "notmuch help" outputs to stderr?
|
||
|
|
Message-ID: <20091118005829.GB25380@dottiness.seas.harvard.edu>

I'm just noticing that 'notmuch help ...' outputs to stderr, which
|
||
|
|
isn't terribly intuitive. For example, the obvious invocation:
|
||
|
|
|
||
|
|
notmuch help | less
|
||
|
|
|
||
|
|
...isn't terribly helpful.
|
||
|
|
|
||
|
|
I've attached a patch that lets usage() take a FILE * argument so that
|
||
|
|
you can output to stderr in response to usage errors, and stdout in
|
||
|
|
response to an explicit request.
