I am writing a Perl program that uses curses for output and move the cursor, and color characters. Previously, when I was working under windows I use Komodo it was able to run an external console.
Now I work in Linux environment and use eclipse + epic. If you try to just run the script, it uses the internal console eclipse, which is very cut. You can just run the script using external tool, but I'm interested to debug using external console window. Is this possible?
Unfortunately, use of a File and /dev/pty/1 does not help in solving my problem.
The fact is that in this case it is impossible to get the characters introduced in the console through curses getch(). Always returned 1 instead code of pressed key.
Here is an answer that will take you most of the way (based on post #6 of: http://ubuntuforums.org/showthread.php?t=743131, although since then, in the "Indigo" and "Juno" versions of Eclipse, things have changed somewhat, and this answer is up to date):
Go to "Run -> Debug configurations". Click on the (fourth) "Common" tab. Go to the third frame from top, and there, check-mark the checkbox which says: "File". Enter the file name of the console window you want your output in.

I have seen this link, and want to make interactively debug Python code running in PyXLL work via that eclipse_debug.py.
So I have done the following:
1) erase PYTHONPATH in the control panel of Windows (as a result, echo %PYTHONPATH% returns %PYTHONPATH%).
2) modify only the first line of eclipse_debug.py to be eclipse_roots = [r"C:\my_path_to\eclipse"].
3) add eclipse_debug.py to pyxll.cfg
4) define a function hello
5) launch debug servier in eclipse, and then launch Excel, and then reload PyXLL
Here is a screenshot:
1) So, it shows that the function hello does work.
2) However, I don't see any excel menu item related to debugger, whereas their link promises This module adds an Excel menu item to attach to the PyDev debugger, and also an Excel macro so that this script can be run outside of Excel and call PyXLL to attach to the PyDev debugger. In other words, I don't see how interactive debug is enabled here.
Could anyone tell me what this eclipse_debug.py supposed to do?
Well, from what I can tell by looking at it, eclipse_debug.py adds the PyDev Remote Debugger (http://www.pydev.org/manual_adv_remote_debugger.html) to the PYTHONPATH and starts it.
Now, how do you make a Python script such as eclipse_debug.py appear as a menu in PyXLL is something I'm not familiar with.
The most likely cause is that it's looking for pydevd but is unable to find it on your python path or where it's looking under the eclipse root. If that's the case there will be some output in the pyxll log file and that will be why the menu item is not appearing.
You should check the log file for errors, and hopefully that will tell you what is going wrong.
I am writing a small FLTK (GUI) program on windows 7 using Eclipse Kepler. My "int main()" function is not even set to receive any command line arguments, yet every time I build the program exe and run it a command line pops up being the GUI interface.
Does anyone know how to suppress this? I do not need a console display for any input or output etc. as this is all controlled via the GUI interface.
Thanks.
It has nothing to see with eclipse. It's a standard behaviour of c++ applications on Windows. Look for console on this page. You will find how to disable it.
The shortcut key is F11 to start debugging. But issue is that I have to be on that file and then hit F11 to start debugging.
Eg.
my file to launch the application is "launch.py" and "example.py".
example.py is open in the editor whereas launch.py is not.
Now, if I hit F11 it will try to launch the application using "example.py" and terminates due to error (as expected).
So then I have to open the "launch.py" in the editor and then hit F11 to start debugging the application.
Is there any neater way to configure the debugging, so that it starts the application in single hit/key?
Edit: example.py is some other file (some module). It does not launch the application.
As this PyDev Eclipse Tutorial suggests:
After the first run, if you type Ctrl+F11, the last file ran is re-run. Or, if you type just F11, a debug session is started with your last run. Let's test this...
Note: This behavior changed in Eclipse 3.3 -- but it's generally recommended to restore it in the preferences at: window > preferences > Run/Debug > Launching and set the Launch Operation to Always launch the previously launched application.
This tutorial will always consider this as the default option.
So, did you have this option selected?
If you have launch at least once launch.py, then you can re-launch it easily.
Although this isn't strictly an answer to what was asked initially, it might help someone looking here that had the same problem as me...
I'm a Java developer mainly, so have the Java view open almost all the time. However, sometimes I want to run some python file to test something (or just create a quick python script, and run it)...
In the Java editor, if the current class has a main(String[] args) method, I run it with (and popup the dialog to ask me what exactly I'd like to run in the middle)
alt+shift+x, j
Unfortunately, that doesn't work in the Python view, and I've not found a similar solution - it just asks me if I'd like to run it as a Java app... however, as the VonC says, you can run the last run thing (provided you've set the preferences accordingly) with
ctrl+f11
and this seems work well with python run configurations too.
But... What if the last thing I ran was a Java program, but I now want to run the active .py file? Previously, to run the .py file, I'd have to go digging through the buttons on the toolbar with the mouse, and I tend to prefer keyboard shortcuts...
Solution! So, finally I come to the actual useful bit of this answer - I just discovered by accident (typing Ivan's suggested shortcut, but missing!), it appears that
f9
will run the currently active python file.
Hope that helps someone get just that little bit faster...
I use CTRL+SHIFT+F9 to relaunch the previous debug configuration in Pydev.
Has anyone any idea why the resulting exe from a build comes with a console?
I've built an EXE and it shows up with the window it should (the right one), and a console window (the left one - obviously).

This behaviour is the same for the debug - exe and the release - exe.
When I start it from Eclipse the console window does not show up.
(Eclipse Galileo / MinGW / C)
Find the linker settings, and add the -mwindows switch.
you might look into this here surely answers why Eclipse is not opening your console window
There seems to be no way to get a java.io.Console object when running an application through Eclipse. A command-line console window is not opened with the application, as it is run as a background process (background to Eclipse?). Currently, there is no Eclipse plugin to handle this issue, mainly due to the fact that java.io.Console is a final class.
All you can really do is test the returned Console object for null and proceed from there.
as far as your console window popping is concerned, you might be using System.console in the application
Hope this Helps
I'm currently writing some ncurses code and the native Eclipse (3.2.2) console can't display its graphics. I'd instead like to run the program through xterm. What I want is to be able to start xterm and run from there. I'd prefer to not get involved with any plugins or that jazz. Just something simple.
EDIT
So I have the answer and it was pretty simple...
Run -> External Tools -> External Tools -> New Launch Config...
Then select location of your terminal emulator. /usr/bin/gnome-terminal in my case.
after that set the appropriate arguments. "-e ~/ncurses/start" in my case.
Then make sure you aren't allocating a console by unchecking that option in the "Common" tab.
Annon add to his question:
its a pain to keep switching back and forth from eclipse and the terminal. I'm looking for a way to just hit something like"F5" and have it run my ncurses program in a new xterm terminal process
The simplest way to do that is to report the command line into an external tool configuration, and point eclipse to use a shell (like described in this program)
In the argument, you will add the command line eclipse execute (command line which can be retrieved as mentioned in the second part of this answer below).
Of course, replace 'cmd.exe' by the shell of your choice, and try not setting the 'Allocate Console' checkbox in the Common tab of that external launcher.
To launch through a xterm, without eclipse involved (not what you are asking for, just keep here for archive)
You can launch your program through Eclipse (Run Configurations), and observe through a 'ps' command the exact Java command line used.
Or launch it in debug mode, and right click the task in Debug view and open Properties. It will show the command line, as documented here.
Then launch that command line directly in your console (Eclipse being not involved at all at this point).
