I have PyCharm Professional Edition 3.5 5.0 configured to
use IPython when possible
and in my Run/Debug Configurations I set
show interpreter afterwards
I use the interactive Interpreter a lot and I really like IPython, but there are some things that I don't like about the way this is handled in PyCharm:
any
input()in my programs return empty strings.Additionally, when an error occurs I can't interact with the Program anymore. (you can when you run a Python program with the
-iflag)There is a lot of space between the last line in the Console and the current line
In IPython the ...: prompt in a code block isn't indented 2 spaces and therefore not aligned to the In [?]: prompt.
- When an error occurs I get something like this:
Traceback (most recent call last): File "C:\Program Files (x86)\PyCharm\helpers\pydev\pydev_run_in_console.py", line 69, in <module> globals = run_file(file, None, None) File "C:\Program Files (x86)\PyCharm\helpers\pydev\pydev_run_in_console.py", line 29, in run_file pydev_imports.execfile(file, globals, locals) # execute the script File "C:\Program Files (x86)\PyCharm\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc) File "C:/Users/ca/Python/Bundeswettbewerb Informatik/Aufgabe2/Ameisen.py", line 133, in <module> function_that_caused_error()
I don't need/want to see the traceback from the internals.
- When running a file IPython needs to be started which takes some seconds even if I'm not going use the interpreted afterwards. I would like PyCharm to start IPython after the program has ended or when I start debugging (you can start IPython in an interactive console by doing
import IPython; IPython.start_ipython()
There are some other minor things that I don't like:
When IPython is started it prints a lot of text to the console. I don't want to see any of it except maybe the version number (you can usually do this with the
--no-banneroption, but adding it to the interpreter options doesn't work)when you type something and press
Upit replaces what I have written with the last item of my history instead of replacing it with the last item of my history that start with what I have typed. Plain IPython does this.I would like to have automatic code completion without having to press
Ctrl + Spacein the console
The "problems" are ordered by importance. Does anybody know how to change some of them? I could stop using IPython which would solve the second , the third and the fourth problem, but the other ones would still persist. All of this behavior (excluding the IPython stuff) is implemented very well in PyScripter.
EDIT:
I have found solutions to the first two problems and the problem with the IPython banner. The source for the PyDev interactive interpreter (which is used by PyCharm) is located, on Windows, in C:\Program Files (x86)\PyCharm\helpers\PyDev (path my vary of course).
So the first problem can be solved by editing the file _pydev_imps/_pydev_execfile.py. Wrap line 18 (exec(compile(contents+"\n", file, 'exec'), glob, loc)) in a try ... except block with the following code as the exception handler import traceback; traceback.print_exc(). This will terminate your Python program if there is an error while letting you interact with the variable afterwards.
Problem 2 can be solved by editing the fire pydev_run_in_console.py. Add this import at the beginning of the file: from pydev_console_utils import StdIn and insert sys.stdin = StdIn(interpreter, host, client_port) after what was line 61 before adding the import.
In order to solve the problem with the banner you have to download the most recent version of the PyDev source here and replace the files pydev_ipython_console and pydev_ipython_console_011 by their newer versions. In the newer version of the first file the __init__ method in line 22 has a argument called show_banner with the default value True. Change this to False.
