如何在将现有对象传递到该控制台的同时在我的应用程序中生成IPython qtconsole [英] How can I spawn an IPython qtconsole within my app while passing existing objects to that console

问题描述

我试图在我的应用程序中嵌入一个IPython qtconsole，类似于我可以嵌入一个IPython文本控制台，因此：

I am trying to embed an IPython qtconsole in my application, in a similar way that I can embed an IPython text console, thus:

from IPython.frontend.terminal.embed import InteractiveShellEmbed
myobj={'jason':10}
shell = InteractiveShellEmbed()
shell.user_ns = myobj
shell()

我可以使用

from IPython.frontend.qt.console.qtconsoleapp import IPythonQtConsoleApp
app = IPythonQtConsoleApp()
app.initialize()
app.start()

但是这无法访问现有对象。

我可以在我的应用程序中启动一个可以访问现有对象的内核，使用：

I can start a kernel in my application which has access to existing objects, using:

import IPython
myobj={'jason':10}
IPython.embed_kernel(local_ns=myobj)
#No more code executes

然后使用

ipython qtconsole --existing

或者，在另一个python脚本：

Or, in another python script:

from IPython.lib.kernel import find_connection_file
from IPython.frontend.qt.console.qtconsoleapp import IPythonQtConsoleApp

cf=find_connection_file("*")
app = IPythonQtConsoleApp(existing=cf[-1])
app.initialize()
app.start()

但这些不是单片解决方案，都需要另外一个shell。内核在一个不产生的线程中运行，因此在内核存在之前不再执行代码。

But these are not monolithic solutions, both require another shell. The kernel runs in a thread that does not yield, so no more code executes until the kernel exists.

所以，我的问题是，我怎样才能实现上述目标脚本？

So, my question is, how can I achieve the above in one script?

我尝试过使用线程和多处理，但由于 embed_kernel（）永远不会返回，显然必须在 IPythonQTConsoleApp之前运行（）或连接文件将丢失，我不知道如何管理它。

I've tried using threads and multiprocessing, but as embed_kernel() never returns and obviously must be run before IPythonQTConsoleApp() or the connection file would be missing, I don't see how to manage this.

PS如果有一个代表大于1000的人请添加一个qtconsole标签。

P.S. Will somebody with a rep of >1000 please add a qtconsole tag.

推荐答案

要嵌入内核而不阻塞，请看一下从IPython存储库此示例。 IPython知道一些巧妙的技巧，可以将自己与Qt事件循环集成，因此您可以同时运行控制台和应用程序。对于交互式调试这样的事情，这是可行的方法。

To embed a kernel without blocking, have a look at this example from the IPython repository. IPython knows some clever tricks for integrating itself with the Qt event loop, so you can run a console and your application at the same time. For things like interactive debugging, this is the way to go.

如果您需要将控制台嵌入到您自己的应用程序中，我们刚刚合并一个进程内核。请查看此示例。在下一个版本之前，您需要使用IPython开发版本，但是进行一些早期测试会很棒。

If you need to embed the console into your own application, we've just merged an in-process kernel. Have a look at this example. You'd need to use IPython development versions until the next release, but it would be great to get some early testing.
