I'm using PyCharm, but I assume that this is similar for all the JetBrains products.
PyCharm has a very convenient UI for editing runtime configurations.
But currently I feel like there is too much UI between me and the actual code execution.
I'm using python + docker and I would like to know what exactly the IDE is doing.
Is it possible to export a runtime configuration to terminal commands?
If you start a run configuration, you get a 'run' tab at the bottom of your window which shows a shortened version of the command. Basically the interpreter and the script. But it definitely doesn't show everything that is going on (for example, in my python+docker setup the published ports are not shown).
Playing around with the UI, I couldn't find the shell version of my runtime config.
And in the docs, I didn't find anything either.

I'm trying to just build webkit on windows. As usual I started with webkit site and trying to get developer tools setup. I'm struck basically at the cygwin Installation itself.
The cygwin-downloader gets all the packages and runs the setup normally.
As per the installation instructions, I selected the Install from Local Directory Option (cygwin install and source package directories are different).
There was some initial turbulance in finding the packages, somehow i could let it find the packages. The screen looks like this now.
I selected the packages (all) and then proceeded with next. It just ran very fast and exited saying nothing needs to be installed. It looked like this.
After I ran the cygwin shorcut from the desktop its shouting something is missing.
I don't understand what am I missing here. Also at some link it says we need a port to build webkit. If thats the case, how does anyone port webkit to their applications without building the webkit alone?
I know this is not a programming question. but this will help most of the people who are taking baby steps in understanding and build WebKit. Thanks!
According to this, it's seems a cygwin-downloader's bug.
However, there is a workaround...
Just copy {cygwin-downloader}\setup.ini file to a {cygwin-downloader}\x86\ directory. Then reopen setup.exe. It will show you a package list without turbulence. You don't need to click all from the package list. Just click Next.
I have been writing grails applications on Windows, and when I am editing the .groovy files and save they are automatically compiled while the application is running and the changes are available without restarting the app. On OSX this is not happening, in neither interactive mode or by starting the application with grails run-app.
Looking up online I couldn't find a reason for this, and also I know other people working on OSX where this feature works.
Any suggestions as to what might cause this?
Grails 2.3.7
OSX 10.9.4
Java 1.7.0_55
If you are not running in forked mode, you will need to specify the -reloading explicitly.
Starting at some point, the initial JVM has reloading disabled and forks a new JVM with options specified in the grails.project.fork = [...] in BuildConfig.groovy.
As an alternative to passing -reloading each time, you can also modify the startGrails script included with the distribution and change the following option to false:
DISABLE_RELOADING=false
For me, the startGrails script is found in the GVM directory at ~/.gvm/grails/2.3.11/bin/startGrails.
I'm looking for effective way for step-by-step debugging NodeJS server code. At this moment I use dozens of console.log()'s and it's extremely hard. The perfect tool is one that would allow me to check the values of every variable in stack and trace my program line by line. Prefered OS = MacOS/Linux. Is it possible?
Basically, Node.js is built on top of V8, so its debugging capabilities are also built on top of V8's debugging capabilities.
V8 has an included debugger which can be accessed via TCP on port 5858.
So basically all you need is a frontend which is able to connect to port 5858 and talk V8's debugging protocol.
One option is to use node-inspector which basically provides a debugging UI in your browser. Unfortunately, it does only work with Google Chrome and Apple Safari (which for me is no problem, but there may be others ;-)).
Another option is to use a plugin for Eclipse.
And, last but not least, the built-in debugger of Node.js (which always reminds me of MS-DOS's edlin) is also just a front-end for this TCP debugger, just a built-in one.
And of course, there are much more options ... these three were just the first three ones that came to my mind ;-)
How about this?
You can try to test for Nodeclipse version 0.2.0 beta.
http://www.tomotaro1065.com/nodeclipse/
It will help you to debug node apps easily.
GENERATING OF EXPRESS PROJECT
Select the [File]-[New]-[Project] menu.
Select [Node]-[Express Project], and push [Next] button.
Enter [Project name], and push [Finish] button.
DEBUGGING
Open the JavaScript source files that you want to set breakpoints.
Double-click on the ruler at the left end of the line you want to set a breakpoint.
If you want to remove a breakpoint, double-click on the ruler again.
Select the main source file of Node Application on the Project Explorer,
open the context menu by right-clicking,
select the [Debug As]-[Node Application] menu.
Use node-inspector to provide the node debugging environment you're looking for. It's fantastic.
Check WebStorm. It is a great IDE, and also you can directly run your nodejs code, or connect to a debugging-enabled node process already running. In both cases, WebStorm provides what you are looking for: trace program execution line by line and on every line check the state of every variable.
Try nodeunit npm module for testing nodejs server side codes.
Even though question is very old, there is a awesome IDE from Microsoft "Visual Studio Code" which is developed in intention with Javascript (Typescript) which is capable of debugging Node JS projects
Checkout this link https://code.visualstudio.com/docs/nodejs/nodejs-debugging
node inspect built-in CLI step debugging
It took a while, but at some point Node finally added built-in debugging:
node inspect main.js
and this leaves you at the first line of the program.
Navigate with:
n step to next line
s step into function
c continue
o step out
h get help
In order to view variables or inject code, you need to first enter REPL mode with:
repl
and then you can run commands as in a node interactive session, e.g. to see the value of a variable just write the variable name:
myvar
It is awkward to have to type those four characters repl all the time, but I don't know any alternative.
You can also add a debugger statement to where you want to break in the program after a c:
const i = 1;
debugger;
i = 2;

Tested in Node.js v10.15.1, Ubuntu 19.10.
One of Xcode's most powerful features is it's Intellisense completion, which brings up a list of potential candidates as you type the name of a Foundation/Cocoa/UIKit API. I am very interested in MacRuby, PyObjC, or the more recent RubyMotion, however without code completion these tools seem like more trouble than they're worth.
Is there any code completion feature (not necessarily Intellisense) for any of the three technologies above, for any text editor (but preferably for Vim or Xcode)? Bonus points for an IDE solution which allows for building and running the application in a single command (like Xcode's Run button).
It's my understanding that Xcode 4 dropped support for MacRuby/PyObjC, so Intellisense is no longer available. Should I install Xcode 3 alongside Xcode 4 for the code completion? How is everyone else doing it (surely you guys use some form of code completion -- I can't believe anyone can remember all the classes in Foundation/Cocoa/UIKit)?
RubyMotion comes with vi ctag support. Run rake ctags to create them.
FWIW, there is a Code completion package for Sublime Text 2, which can also be installed via the package manager of the Sublime text.
And it seems to work rather well for me.
Yes, you can give yourself Vim code completion by running $ rake ctags in the root directory of your RubyMotion app. To take that a step further, use a shell script to generate ctags automatically every time you create a new RubyMotion app. This article shows how to build such a script:

I know that in a normal NDK build, the C++ libraries are built and packed into an apk file. But how can I automate this in Eclipse? I have tried following http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ to run the native-activity sample that came with the NDK, and it ended up not working. Even after I got past most of the reference errors via including, nothing happens when I run it as an Android Application (with a Motorola phone plugged in).
I have looked around quite a bit about this and am still stuck, so I'm open to suggestions at this point. Thanks!
(Please keep in mind that I'm using MinGW/MSys on Windows 7, mostly for running scripts with bash)
I've just decided to go with an Ubuntu VM and use that, and with some tweaking it seems to be working the way it should. I used a combination of http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ and http://developer.android.com/sdk/ndk/overview.html#native-activity to get everything set up. Also a very important note, go to C/C++ General -> Code Analysis -> Launching in your Eclipse project settings and disable both of those options for any native activities you make. I'm not sure if there's a good way to set the libs and includes up for it to work, but currently live bug checking screws things up in the NDK, and I can currently build successfully without it. Plus it'll still mark errors in red after a failed build, so you shouldn't be completely in the middle of nowhere when finding errors.
