在现有的代码片段中,我有
import sys
from code import InteractiveConsole
class FileCacher:
"Cache the stdout text so we can analyze it before returning it"
def __init__(self):
self.reset()
def reset(self):
self.out = []
def write(self, line):
self.out.append(line)
def flush(self):
output = '\n'.join(self.out)
self.reset()
return output
class Shell(InteractiveConsole):
"Wrapper around Python that can filter input/output to the shell"
def __init__(self):
self.stdout = sys.stdout
self.cache = FileCacher()
InteractiveConsole.__init__(self)
return
def get_output(self):
sys.stdout = self.cache
def return_output(self):
sys.stdout = self.stdout
def push(self, line):
self.get_output()
# you can filter input here by doing something like
# line = filter(line)
InteractiveConsole.push(self, line)
self.return_output()
output = self.cache.flush()
# you can filter the output here by doing something like
# output = filter(output)
print output # or do something else with it
return
if __name__ == '__main__':
sh = Shell()
sh.interact()
如果 IPython 可用,我如何修改它以使用 IPython 的交互式 shell,如果可能的话不更改其余代码。
我尝试将第 2 行from code import InteractiveConsole
替换为,from IPython.core import interactiveshell as InteractiveConsole
但显然,它不是一个可直接互换的类。
什么是最好的方法来做到这一点(对代码库的其余部分的改变最小)除了存在时IPython
优先使用code
模块IPython
吗?
