I have problem with Eclipse LDT. When I run my test Lua app, it executes just fine using JNLua inside JavaVM environment. But according to this tutorial, when I reference native lua.exe interpreter and set it in Run Configuration as Runtime Interpreter, Run Configuration disables Launch script: and nothing is executed. When I run a same script with a same native local Lua interpreter 5.1, everything works just fine.
So, what is the problem with LDT? Has anyone had the same experience?
EDIT
I've managed to run local lua.exe from Lua Development Tools stand-alone product, but still it doesn't work as Eclipse plug-in.
I'm not sure it's a bug.
I guess when you register your interpreter, you uncheck the checkbox : "Accept file as argument"
This mean LDT will not manage the file to launch (that's why the Launch script is disabled)
The standard lua interpreter support file as argument and -e option, so the two check box should be checked. (It's the default value)
It looks like a bug ... Would you mind filing it in the Koneki bug tracker?

In a VScode C/C++ programming setup on Windows 10 system, the "C/C++ Extension Pack", "Code Runner", "WSL" extensions are installed, which use Alpine Linux target on WSL on this PC. Alpine Linux WSL instance has the gcc dev environment, build-tools, gdb etc. installed, apart from the necessary VScode extensions needed inside WSL.
In this environment I am able to write C/C++ programs, build them, execute them, interact with them through the built-in terminal. I use the "Code Runner" "Run C/C++ file" shortcut button to build(if necessary) and run individual C/C++ program files (there is no Makefile and these are simple programs all thrown in a single folder, not in a project structure).
Recently however, I noticed that whenever I try to "Run C/C++ file", debugger is also launched and I get a screen like this (notice the 2 yellow/orange arrows indicating what I am trying to draw attention to):
I do not remember this being the case earlier, but I think this started after I tried to debug a program by setting a breakpoint, which I later cleared. I've also ensured that "Run > Remove All Breakpoints" is done, to make sure that there are absolutely no breakpoints. Therefore wondering if:
it is normal for debugger to get launched in this manner ?
if not, what exactly might have caused it ?
finally, what can I do to make sure that the debugger is not launched, when all I want to do is "Run" ?
In "Code Runner" settings file, I did not find anything that might control this behaviour, but then I am quite new to VScode so not sure if I am missing anything obvious.
I wanted to see how the code of FFMpeg works. So what I did is imported this project in eclipse. When I run the binary from the command line, it decodes the entire video without any problem and displays it as well. However if I run exactly same binary from the eclipse, it fails. It fails when the binary executes the following statement -
instance->display = XOpenDisplay (NULL);
Can anyone tell if there is any special requirement for running X11 apps in eclipse? I have linked the necessary libraries in the code. Also the binary works perfectly from the command line.
Had a similar problem developing with ROOT gui classes.
I solved the issue adding the env variable DISPLAY to :0 in the run configuration tab.
Every time I try to run a .py module it just opens in Firefox.
I'm running Aptana in OS X 10.6
If you installed and configured PyDev, it should work.
Make sure you use the correct "Run" command. Prefer "Run as Python module", avoid "Run on Server".
If that doesn't help, edit your question and give an exact example what you do (which menus/buttons you click, etc).
See: http://pydev.org/manual_101_run.html for details on running a Python module (make sure you read the whole getting started: http://pydev.org/manual_101_root.html which should help you in getting your environment setup and gives some tips to properly use PyDev).
I used a same workspace for both python and java , and met the same problem.
If I change a new workspace, the Run As works. So i think there is something wrong with workspace settings.
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.
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).
