[more about mocking stdio]
In addition to mocking stdio for testing, stdio_mgr can also be used to wrap functions that directly interact with stdio. Example:
>>> def embellish(func):
... def func_wrapper(s):
... from stdio_mgr import stdio_mgr
...
... with stdio_mgr() as (i, o, e):
... func(s)
... content = o.getvalue()
... newcontent = '*** ' + content.replace('\n', ' ***\n*** ')
... newcontent = newcontent[:-5]
... print(newcontent)
... return func_wrapper
>>> @embellish
... def testfunc(s):
... print(s)
>>> testfunc("""\
... Foo bar baz quux.
... Lorem ipsum dolor sit amet....""")
*** Foo bar baz quux. ***
*** Lorem ipsum dolor sit amet.... ***1 maintainer
