How to increase the ipython qtconsole scrollback buffer limit -

when load ipython 1 of:

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

the output buffer holds lastly 500 lines. see run:

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

is there configuration alternative this? i've tried adjusting --cache-size not seem create difference.

quickly:

ipython qtconsole --ipythonwidget.buffer_size=1000

or can set permanently adding:

c.ipythonwidget.buffer_size=1000

in ipython config file.

for discovering sort of thing, helpful trick is:

ipython qtconsole --help-all | grep pattern

for instance, had 'buffer', so:

$> ipython qtconsole --help-all | grep -c 3 buffer ... --ipythonwidget.buffer_size=<integer> default: 500 maximum number of lines of text before truncation. specifying non- positive number disables text truncation (not recommended).

if ipython used different name expect , first search turned nothing, utilize 500, since knew value wanted change, find relevant config.
