Using Andrew's examples from the PEP:
def usage(outfile):
outfile.write(
"""Usage: %s [OPTIONS] <file> [ARGS]
Meta-options:
--help Display this help then exit.
--version Output version information then exit.
""".dedent() % sys.argv[0])
self.runcommand("""\
if 1:
import sys as _sys
_sys.path = %r
del _sys
\n""".dedent() % (sys.path,))
class WrapTestCase(BaseTestCase):
def test_subsequent_indent(self):
# Test subsequent_indent parameter
expect = '''\
* This paragraph will be filled, first
without any indentation, and then
with some (including a hanging
indent).
'''.dedent().rstrip()
result = fill(self.text, 40,
initial_indent=" * ",
subsequent_indent=" ")
self.check(result, expect)
And if the loading of the textwrap module is deferred to the first call to
dedent(), then it wouldn't even need to incur any extra start up overhead.
Although that last example is a bad one, since you end up testing textwrap
against itself ;)
Cheers,
Nick.
