I cannot for the life of me figure out how to run and debug a c++ file in vscode. There are always at least one or two things wrong.
I've already used the basic tutorials, but they don't seem to work for me.
Can someone explain it to me like I am 5 years old? Or point me in the direction of a place that will? I am totally burnt out and feel like a total dunce. I can't get a hello world program running and it is driving me crazy. Any help would be appreciated.
Is it on Windows or Linux ?
If on windows, first download and install the mingw setup. You can find it here :
https://sourceforge.net/projects/mingw/
After installation, add the location of th bin of g++ to PATH so that you can access it via the command line.
You can also add some extensions to your VS Code to make debugging C++ code easier, then in VS Code, open the terminal, and , while in the directory where you have your cpp file, simply do a g++ filename.cpp to compile, then run the executable, a.exe, unless otherwise specified in the previous command .
Hope this helps
Make sure that you have c++ compiler I prefer mingw.
Open vscode and go to Extensions or by keyboard shortcut ctrl + shift + x.
Search for .run and install
Search for C/C++ and install.
Go to settings ctrl + ,
By GUI
In the search bar, search for code runner and Code-runner: Run In Terminal will be unticked by default. You tick it and close settings tab. Refer the pic for better understanding.
Finally create a C++ file and save. Go to Terminal and select Run Build Task then click ctrl + alt + n to run the code. Again refer image for better understanding.
This should work, but if still didn't work let me know. Else refer any youtube video , you might have committed small mistake.
Let me know if this didn't work my dear 5 years old guy ;)

Apologies for incredible ignorance. First time ever looking at or trying coding in any form and all naturally a bit confusing and overwhelming.
Trying to keep it super basic I'm attempting to build something basic for Amazon Echo by working through this article - https://developer.amazon.com/blogs/post/Tx3DVGG0K0TPUGQ/updated-alexa-skills-kit-fact-template-step-by-step-guide-to-build-a-fact-skill
Have got to Step 2.3
Once you have the source downloaded [done], node installed and npm updated, you are ready to install the ASK-SDK. Install this in the same directory as your src/index.js file for your skill. Change the directory to the src directory of your skill, and then in the command line, type: npm install --save alexa-sdk
I've moved the SDK into the same folder as the source - in downloads folder. Am confused on changing the directory to the same as my skill. As far as I know there is no skill yet so not sure where to move it to.
When type in npm install --save alexa-sdk
returns
npm WARN enoent ENOENT: no such file or directory, open '/Users/OwenLee/package.json'
npm WARN OwenLee No description
npm WARN OwenLee No repository field.
npm WARN OwenLee No README data
npm WARN OwenLee No license field.
working on a mac so don't really know how/where to access this, but assuming this is where i need to move the files to?
Very sorry for baby-basic knowledge. Just trying to at least get a foot in the door as know need to learn this stuff but everything i read seems to assume i already have a working knowledge of coding : S
any help would be awesome - inc. any advice on steps after that you can probably see i'll trip up on
thanks!!

So as far as the directory /Users/OwenLee/ this would be your home folder on a Mac. The Root / of your HDD can be reached through Finder by clicking on Macintosh HD (or whatever you named your main hard drive) in the side bar. If you open up a new Terminal window it will be the directory that the terminal starts in. You should be able to fix your problem by taking the file packages.json, which should be wherever you downloaded the SDK to, and placing it in your home folder, then re-running the command.
Now don't let me change your mind if you're truly committed, but if you have absolutely no experience with programming I would recommend starting with something a bit simpler than Java or Javascript. Object oriented languages can be both very convoluted and difficult to get the hang of for beginners (I personally have been writing native languages like C for years and am just now starting to understand how Java works.).
If it is an option I recommend starting with a language that your Mac has built in support for. Perhaps start with Bash scripting or Apple Script making basic scripts to do things you find tedious to do manually in a terminal, or get to know the basics of processor-native languages like C & C++ by making some basic programmes to display text when it is run, or to ask the user to type something, and say back what they typed. Finally since you are on a Mac you can get Xcode for free in the app store, it will configure itself and you could play around with it to learn how macOS handles windows, perhaps start by making a basic programme window with a few buttons that do different things when clicked.
If you have any interest in my suggestions you can find some info about bash scripting here: https://linuxconfig.org/bash-scripting-tutorial the tutorial says it assumes the reader has no previous knowledge of Bash, and most commands should work fine in the version of Bash built into your Mac's Terminal app.
If you take more interest in C++ this is the site that I used to learn to write it, and learn how native languages work: http://www.cplusplus.com/doc/tutorial/
Finally here is a basic C++ programme called "Hello World", it is somewhat of an initiation rite of C/C++ students to write this programme and learn how each part of it works:
//HelloWorld.cpp the double slash tells the compiler and user that everything after it on this line is a comment, not code//
#include <iostream> //The octothorp '#' lets the compiler know it needs to use the library named inside the pointed brackets '</>' when it builds the programme. 'iostream' stands for In-Out Stream, and handles basic text, and basic processor commands//
using namespace std; //This line tells the compiler that any line that says to show text or ask the user to type something should use regular text and not a special format//
int main() //'int' stands for integer, any time you make a variable that contains only an integer you should put this in front of it's name, and 'main' is the name of the integer. The empty parentheses tells the compiler that this is a function, rather than a number//
{ //The open curly bracket '{' tells the compiler where the function starts
cout<<"Hello World"; //'cout' stands for 'character out' and is for showing basic text in the terminal window. The double pointy 'out' brackets '<<' tells the compiler that the text should be sent out of the programme rather than loaded into a variable, the text inside the quotes is what will be shown on the screen, and the semi colon tells the compiler where the command ends, it has to be put at the end of any command that is inside of a function//
return 0 //The command 'return' is for telling the compiler whether or not an error has occurred, 0 means the programme ran fine, 1 means something went wrong, either way the programme closes when it runs the command 'return'//
} //the closed curly bracket tells the compiler where the function ends//
Good luck with your programming, and if you have any questions unrelated to this thread please feel free to private message me, or create a new question and tag me in it so that I get notified.
I'm trying to package some code up as an ANE, something we've done before in house. However we're currently stuck on an ADT error which I can't seem to wrap my head around.
When running the following from a sh file, I'm getting an error.
Shell script:
ADT="/Applications/air/bin/adt"
NAME="VideoRoll"
AFILE="libVideoRollANE.a"
$ADT -package -target ane $NAME.ane extension.xml -swc $NAME.swc -platform iPhone-ARM -platformoptions platformoptions.xml library.swf $AFILE
Error:
platformoptions.xml is not part of a Mac OS X Native Extensions
framework
All of the files are in the correct place and being clearly picked up by adt, as I'd assume there would be something else I'd be getting back. If you're after the source code, it's an open source library on bitbucket that I've forked and made a couple of changes to. I'm trying to compile it with Adobe AIR SDK 20 to try and fix an issue we're getting but I'm struggling to just build it from the base source right now. The source can be found here: https://bitbucket.org/lostirc/videoroll/src .
Any suggestions would be great, I'm up for trying anything now. I've modified nearly everything I can think of and tried various different orders for the command, it seems if I remove the platformoptions flag and value, then it gives the same error about library.swf, so I'm not sure it's directly related to the platformoptions.xml.
I worked around the problem by running the same command on Windows. This isn't really a solution but a potential workaround for anyone having the same issue. If anyone can post a good answer then I'll accept that, but for now this is the best answer I've got.
I am not finding any way to search in whole application in my nitrous box. Basically I am looking for "Find in Folder" search option using which I can search for any string in my whole app.
Also I am not able to open a particular file. In sublime we use to open any view file using
CTRL + P.
Let me know if anyone of you has any idea or these features are not present in nitrous box
Thanks,
Dean
Unfortunately the IDE is very basic for now, so you can't simply open files with shortcuts, you need to use the folder tree...
About the "find in folder" feature, you can you use grep command as a workaround... example: $ grep "redeem reward" /home/tom/*.txt This is not really efficient, since you can't invoke the IDE from the terminal... but at least you can find what you are looking for...
Hope this helps.
I am trying to run the Playn example projects. I followed every step in this guide to setup new Playn development environment and then this guide to run sample projects.
it seem to work fine but when I try to run the HTML5 version by right click and then going to Google-> GWT compile, nothing happens. I don't see the development mode view poping up to copy the address and paste it to web browser as the guide says. I just get the following in the console window:
Compiling module playn.showcase.Showcase
Compiling 1 permutation
Compiling permutation 0...
Compile of permutations succeeded
Linking into L:\playn-samples\showcase\html\war\showcase
Link succeeded
Compilation succeeded -- 35.187s
Beyond that nothing happens. If I right click and select run as-> web application, I get the pop out saying
Could not find any hosting pages in the project playn-showcase-html
Anybody know what am I doing wrong ?
What you got from the compilation was all good.
"Beyond that nothing happens." is okay.
When you right click on the "playn-showcase-html" project, select "Run As - (g) Web Application", you should get an output to the "Development Mode" tab as "http://127.0.0.1:8888/Showcase.html?gwt.codesvr=127.0.0.1:9997".
If not, check if you have got the following folder structures under the "playn-showcase-html" project:
playn-showcase-html
|...
|--war
|--Showcase.html
|--WEB-INF
|--web.xml
As far as I know, you can't simply compile (GWT) and run the HTML version. This is because, the HTML version requires a local web server (such as jetty/tomcat) to host the files in order for the project to be 'run'. However, a simpler way around this would be to try using ant via Eclipse.
Window > Show View > Ant
Once the window appears (probably on a sidebar), right-click and select:
Add Buildfiles...
When the list of projects appear, expand the project by clicking the small arrow to the left of the project name in the list. Then select the ant build file:
build.xml
That will add the ant build file to your list of active build files.
Expand similarly to look at the ant tasks provided by the build file.
Double click on the appropriate task; in your case:
run-html
OR
Run ant directly on the command-line to get the same results.
In the current version of PlayN a jetty server is being started automatically. Right click on the xx-html project "Run As"->"maven install". This starts the GWT compiler, and starts a jetty server (default port is 8080), then you can run the HTML5 version by typing "localhost:8080" in yout browser.
I've also wrote a more detailed description about this on my blog getting started with eclipse and PlayN , maybe this could be interesting.
Im in the situation that I often send small codesnippets and xml-snippets to coworkers and partners via my outlook.
Has anyone got a good idea or tool that I can use to have my pastes syntaxhighlighted before I paste them into an email.
I was thinking of an intermediate paste to "$fancytool" and then I would have something to copy that will htmlified so I can copy paste it into the "compose email" window.
Edit-More-info:
Im pasting from windows within a VMWare virtual Machine, it might be eclipse, xmlspy, logfiles and other programs
Even-more-info:
I've seen this link how to do it from Vim. Unfortunately it seldom from vim im copying Code, and my email machine hasnt got any vim. The vmware machines has gvim, but I was hoping for an easier way that pasting to vim, saving to file, opening in internetexplorer and then copy/paste
Late but I can give an answer that works.
You need 2 things
putty
access to some Unix server (With vim)
In putty options, Under window → selection , turn the check box on for
Paste in to clipboard in RTF as well as plain text.
Log on to the server using putty.
start vim by typing vim
Paste your text (for example XML ) in to vim.
enter command mode (of vim by pressing ESC) and type
:set syn=xml.
Syntax highlighting kicks in.
Copy the text using mouse and paste it into your email.
5 years too late, sorry, but I've a much simpler solution than the accepted answer.
Use this online tool: http://tohtml.com/
copy the preview from your browser window and just paste into Word or Outlook.
Vim (or GVim) will output your code as formatted HTML. Then as long as your email is using an HTML format you can copy and paste it in.
Just an update on this matter, if you're on Windows, you can install Notepad++ (which is one of the best windows editors anyway), it comes out of the box with a plugin for this: "Copy text with Syntax Highlighting", when you select some text and right click on it.
If you just want the Add-In here it is.
If you want to know how it is done, here is an article on how to write the Add-In.
Comment: svrist mentioned a code paste site with syntax highlighting. Try http://codepad.org/
(don't have enough mojo to comment yet)
This link led me to SciTE.
Looks like SciTE has a Copy to RTF feature:
Edit(vmware upgrade):
But it looks like I am pretty much lost when I use vmware because I cant transfer rtf clipboard items to the vmware host. And I cant install software on the vmware host.
Maybe a paste-site with syntax highlighting?
If you're on Windows, Visual Studio does this automatically. At least it does for me, using Visual Studio 2005 on XP and copy/pasting to both MS Word and Lotus Notes
HeidiSQL does this for sql queries, and the syntax highlighting choices they made are quite readable. However, this will only work for sql queries, not other code. I like Notepad++ for Windows-based systems, and here are some instructions for Notepad++. Several people mentioned VIM for unix/shell environment.
For gVim (Windows), I defined this function and a convenience mapping:
function! HlCopy() range
exec a:firstline.','.a:lastline.'TOhtml'
normal yG
q!
!start /min powershell "Get-Clipboard | Set-Clipboard -AsHtml"
redraw
endfun
vmap Y :call HlCopy()<CR>
How to use?
Enter visual mode with v or by selecting text with left mouse. Then copy the current selection as raw text with y or highlighted text with Y.
Pass range directly (without visual mode): :1,3call HlCopy().
If you are lazy like me, you can set additional options for TOhtml in that function. I have this in my vimrc:
function! HlCopy() range
let g:html_font = "Consolas"
let g:html_number_lines = 0
exec a:firstline.','.a:lastline.'TOhtml'
normal yG
q!
!start /min powershell "Get-Clipboard | Set-Clipboard -AsHtml"
redraw
endfun
vmap Y :call HlCopy()<CR>
