来自Windows XP上的emacs的ipython，没有提示，也没有打印输出

Question

I want to integrate ipython to emacs 23, on windows XP. I could find quite some information online, but nothing did the trick.

The following is required in my ~/.emacs.d/init.el :

• python-mode
• pymacs
• ipython

pyreadline is also installed.

I launch ipython with a bat file (in my system path), with the flags -i and -u.

The information text

c:\Program\emacs-23.2\bin>c:\program\python27\scripts\ipython -i -u

Python 2.7 (r27:82525, Jul  4 2010, 09:01:59) [MSC v.1500 32 bit (Intel)]
Type "copyright", "credits" or "license" for more information.

IPython 0.10.1 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object'. ?object also works, ?? prints more.

does not appear until I write the first command.

I get no prompt. Writing and "executing" numbers do result in the red " Out[n]: " and the number. Print does not give anything. a gives the a colorful ipython error text, ending with NameError: name 'a' not defined .

In other words, the error stream seems ok, the standard output seems ok, but print and whatever is responsible for printing the prompt cannot seem to find the correct stream.

emacs *Message* buffer says:

comint-send-string: Output file descriptor of Python<1> is closed

for every output (not appearing) in the python shell.

Answer 1

Make sure you're using pyreadline 1.6 . Version 1.5 writes to the stream using the console API even when run via Emacs. That causes many problems similar to the ones you are seeing.

我相信它是Python解释器本身，而不是接收-u参数的ipython脚本，即你的文件C:\\Program\\Python27\\scripts\\ipython.bat应该包含类似的东西：

@C:\Program\Python27\python.exe -u C:\Program\Python27\scripts\ipython.py %*
