记录IPython输出？ [英] Log IPython output?

问题描述

有没有办法让IPython的日志记录功能包括输出和输入？

Is there any way to make IPython's logging capability include output as well as input?

这是当前日志文件的样子：

This is what a log file looks like currently:

#!/usr/bin/env python 
# 2012-08-06.py 
# IPython automatic logging file
# 12:02 
# =================================
print "test"

我想再出示一行：

#!/usr/bin/env python 
# 2012-08-06.py 
# IPython automatic logging file
# 12:02 
# =================================
print "test"
# test

（＃是因为我认为需要防止破坏IPython的 logplay 功能）

(the # is because I assume that is needed to prevent breaking IPython's logplay feature)

我想这可能是使用IPython笔记本电脑，但至少在一台我需要它的机器上，我只限于ipython 0.10.2。

I suppose this is possible using IPython notebooks, but on at least one machine I need this for, I'm limited to ipython 0.10.2.

编辑：我想知道如何自动设置，即在配置文件中。现在我的配置看起来像

I'd like to know how to set this up automatically, i.e. within the configuration file. Right now my config looks like

from time import strftime
import os
logfilename = strftime('ipython_log_%Y-%m-%d')+".py" 
logfilepath = "%s/%s" % (os.getcwd(),logfilename) 

file_handle = open(logfilepath,'a') 
file_handle.write('########################################################\n') 
out_str = '# Started Logging At: '+ strftime('%Y-%m-%d %H:%M:%S\n') 
file_handle.write(out_str) 
file_handle.write('########################################################\n') 
file_handle.close() 

c.TerminalInteractiveShell.logappend = logfilepath
c.TerminalInteractiveShell.logstart = True

但指定 c.TerminalInteractiveShell.log_output = True 似乎没有影响

推荐答案

％logstart 的 -o 选项：

-o: log also IPython's output.  In this mode, all commands which
  generate an Out[NN] prompt are recorded to the logfile, right after
  their corresponding input line.  The output lines are always
  prepended with a '#[Out]# ' marker, so that the log remains valid
  Python code.

ADDENDUM：如果您处于已启动日志记录的交互式ipython会话中，则必须先停止记录然后重新启动：

ADDENDUM: If you are in an interactive ipython session for which logging has already been started, you must first stop logging and then restart:

In [1]: %logstop

In [2]: %logstart -o
Activating auto-logging. Current session state plus future input saved.
Filename       : ./ipython.py
Mode           : backup
Output logging : True
Raw input log  : False
Timestamping   : False
State          : active

注意，重启后，输出记录现在为真。

Observe that, after the restart, "Output Logging" is now "True".
