我的目标是调用ipython,同时将所有输入/输出记录到 IPython,并查看如下内容:

stu@stumac ~  $ ipython

In [1]: exit
stu@stumac ~  $

如果我设置,横幅可以很容易地移除

c.TerminalIPythonApp.display_banner = False

在我的 ~/.ipython/profile-default/ipython_config.py档案中。

但是,我如何在记录事物的同时清理初创公司呢?

在全新安装时,如果我在没有参数的情况下启动 IPython,我会看到:

sente@og ~ $ ipython
Python 2.7.3 (default, Jun 20 2013, 12:50:58)
Type "copyright", "credits" or "license" for more information.

IPython 0.13.2 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: exit
sente@og ~ $

如果我在调用 IPython 时传递一个logfile=logfile.txt参数,我会看到:

sente@og ~ $ ipython --logfile=logfile.txt
Activating auto-logging. Current session state plus future input saved.
Filename       : logfile.txt
Mode           : backup
Output logging : False
Raw input log  : False
Timestamping   : False
State          : active

如何在不向终端添加额外混乱的情况下使用日志记录:

Activating auto-logging. Current session state plus future input saved.
Filename       : logfile.txt
Mode           : backup
Output logging : False
Raw input log  : False
Timestamping   : False
State          : active

在其他机器上,我将 IPython 配置为通过.ipython/profile_default/startup/01-log-everything.py包含以下行来自动记录事物:

from time import strftime
import os.path

ip = get_ipython()

ldir = ip.profile_dir.log_dir
fname = strftime('%Y-%m-%d-%H-%M-%S') + ".py"
filename = os.path.join(ldir, fname)

ip.run_line_magic('logstart', '-o %s append' % filename)

这导致与我添加时相同的混乱--logfile=logfile.txt

任何有关如何正确执行此操作的帮助将不胜感激。如果没有别的办法,我可以重定向 sys.stdout,配置日志记录,然后重置 sys.stdout,但我希望有一个不那么骇人听闻的解决方案。

要在没有横幅的情况下登录,请使用 --no-banner 标志。

ipython --no-banner --logfile='logfile.txt'

这可以在带有 --help-all 标志的帮助文件中找到。

ipython --help-all

看了IPython源码后,即:

似乎真正实现我想要的唯一方法 -在启动时完成日志记录而没有任何sys.stdout回显 - 是在初始化日志记录时重定向或静音。

我创建了一个启动文件:~/.ipython/profile_default/startup/01-log-everything.py这样做,代码是:

from time import strftime
import os.path
import contextlib
import cStringIO
import sys


# create a context which we can use for any block which we can use for any
# block which we do not want to print stdout
# -- taken from http://stackoverflow.com/a/2829036/217652

@contextlib.contextmanager
def nostdout():
    save_stdout = sys.stdout
    sys.stdout = cStringIO.StringIO()
    yield
    sys.stdout = save_stdout



ip = get_ipython()

ldir = ip.profile_dir.log_dir
fname = strftime('%Y-%m-%d-%H-%M-%S') + ".py"
filename = os.path.join(ldir, fname)


# stdout is now muted
with nostdout():
    ip.run_line_magic('logstart', '-o %s append' % filename)
