Pydev：发送stdout到一个真实的（tty）终端 [英] Pydev: Send stdout to a real (tty) terminal

问题描述

继续上一个问题（子流程：PyDev控制台与cmd.exe ），有没有办法改变PyDev发送stdout的位置 - 即到tty终端？

Following up on a previous question ( subprocess: PyDev console vs. cmd.exe ), is there a way to change where PyDev sends stdout--namely to a tty terminal?

我遇到了几个没有tty终端已经受到限制。对于子进程模块的情况，我可以使用CREATE_NEW_CONSOLE标志，但在其他情况下，例如在此问题（在控制台中正确打印\r ），PyDev控制台似乎不支持使用转义字符。

I've come across several instances where not having a tty terminal has been limiting. For the case of the subprocess module, I can use the CREATE_NEW_CONSOLE flag, but in other instances, such as in this question ( Print \r correctly in console ), the PyDev console doesn't seem to support using escape characters.

任何想法。

推荐答案

这是目前Eclipse ...（PyDev继承的）的限制。

This is currently a limitation in Eclipse... (which PyDev inherits).

Aptana Studio有一个终端视图，可能用于替换，但目前没有计划这样做。

Aptana Studio does have a terminal view which could probably be used as a replacement, but there are no plans to do so for now.

回答评论下面，从运行的Python程序创建一个新的shell可以使用下面的代码：

Answering comment below, to create a new shell from a running Python program it's possible to use the code below:

import subprocess
import sys
import os
args = [sys.executable] + sys.argv
new_environ = os.environ.copy()

if hasattr(subprocess, 'CREATE_NEW_CONSOLE'):
    popen = subprocess.Popen(args, env=new_environ, creationflags=subprocess.CREATE_NEW_CONSOLE)
    exit_code = popen.wait()
else:
    #On Linux, CREATE_NEW_CONSOLE is not available, thus, we use xterm itself.
    args = ['xterm', '-e'] + args
    popen = subprocess.Popen(args, env=new_environ)
    popen.wait() #This exit code will always be 0 when xterm is executed.
