如何增加ipython qtconsole回滚缓冲区限制 [英] How to increase the ipython qtconsole scrollback buffer limit

问题描述

当我使用以下任何一个加载ipython时：

When I load ipython with any one of:

ipython qtconsole
ipython qtconsole --pylab
ipython qtconsole --pylab inline

输出缓冲区仅保留最后500行。要查看此次运行：

The output buffer only holds the last 500 lines. To see this run:

for x in range(0, 501):
   ...:     print x

是否有配置选项？
我试过调整--cache-size但这似乎没什么区别。

Is there a configuration option for this? I've tried adjusting --cache-size but this does not seem to make a difference.

推荐答案

很快：

ipython qtconsole --IPyWidget.buffer_size = 1000

ipython qtconsole --IPythonWidget.buffer_size=1000

或者您可以通过添加以下内容来永久设置：

Or you can set it permanently by adding:

c.IPythonWidget.buffer_size=1000

$ b你的ipython配置文件中的
$ b

。

in your ipython config file.

为了发现这类事情，一个有用的技巧是：

For discovering this sort of thing, a helpful trick is:

ipython qtconsole --help-all | grep PATTERN

例如，你已经有了'缓冲'，所以：

For instance, you already had 'buffer', so:

$> ipython qtconsole --help-all | grep -C 3 buffer
...
--IPythonWidget.buffer_size=<Integer>
    Default: 500
    The maximum number of lines of text before truncation. Specifying a non-
    positive number disables text truncation (not recommended).

如果IPython使用了与您预期不同的名称并且第一次搜索没有显示任何内容，那么您可以使用 500 ，因为您知道要更改的值是什么，这也会找到相关的配置。

If IPython used a different name than you expect and that first search turned up nothing, then you could use 500, since you knew what the value was that you wanted to change, which would also find the relevant config.
