Can I use IntelliJIdea to code in C++ ? Are there some plug-in to do that ? |
You can try CLion.
I have a problem,when go add actions , not show me plugin chelper :(, |
- You either had not copied it to correct folder or had not restarted Idea since
I installed CHelper from Browse Repository and Restarted the IDE after that I Added All CHelper Icons after Main Toolbar From Menus and Toolbars and I opened Edit Project Settings And When I parse Contest And Press OK NullPointerException And Message null is generated I am not be able install It Correctly plz help me...sorry for my English
Do you have any project open when you click on "Edit Project Settings"?
Yes i have one project open which i created ...
I have had the same problem till I right clicked main directory (Default Folder) and marked it as source, then everything now works. The project originally had only src folder marked as source as it was generated with the commandline project template in intelliJ
» | I have some problems with your CHelper - plugin :-? I've tried it with both IntelliJ IDEA 11 and 10, and I can't get it working I did it in order : 1. Install IntelliJ IDEA 10 2.

- »»
Nothing is working or only contest parsing?
- »»»»»»
Now contest parsing work ,how will it generate automatically Main file,it is not working
- »»»»
It should generate the Main file when you run or debug created configuration
- »»»»»
Hi Egor. This is my configuration: default dir: src/main Archive dir: archive/unsorted Output dir: src Input class: net.egork.chelper.util.InputReader Output class: net.egork.chelper.util.OutputWriter
When I click onRun the selected configuration, it successfully generates a Main.java file under src (so src/Main.java). The generated file includes the classes from your library but the methods are empty. This is what I get:
class InputReader { public InputReader(java.io.InputStream stream) { /* compiled code */ } public int readInt() { /* compiled code */ } }So, I'm getting compile errors.
I installed according tohttps://code.google.com/p/idea-chelper/wiki/MainPage Intellij IDEA 12.1.4 @ Windows
any hints?
UPD: If I leave the output dir empty, it compiles correctly:
- before compiling, it yields "outputDirectory should be under source and in default package".- it then generates the file on the project root directory (so, on the same level as the src directory). The file still has empty methods for your library classes with /* compiled code */ bodies.- I created a sample case and it correctly showed me the results on the intellij console.
» | Hi Egor, Can you tell me how the inline functions work...I cannot figure it out..Suppose I have a method isPrime(int) that returns whether the number is prime or not.I want to use it directly and not write the whole thing everytime.I think the inline code does exactly this.But I dont know how to use it.Could you tell me or better demonstrate it with an example??? |

- »»»
And where do I have to save that class??

I created a class algorithms in src and a static method isPrime(Object a) in that.Then I compiled it. After that when I go to a Task and write boolean check=algorithms.isPrime((Object)a) ,then it is shown in red .i.e. it cannot compile...What should I do...Should I have to restart??

Are you sure your method was public?

Yes it is public...Do I have to change something in the properties file or put the class in a directory under the src??

Ok. now its working .When I created a new directory under src and put the class in it.Thanks for the replies and your time:-) The thing I dont like in this is that it is showing all the methods in that class even if it is not called but some other method of that class is called ..Can this be changed??

» | Does anybody have any insight into how to speed up running the task in Intellij? Right now I am using Egor's library (which is very helpful btw), and that seems to slow it down as it the compiler links things together I suppose. Overall it take between 15-25 seconds for solution to run for me right now, which is not terribly long but for competitions would be nice if it was a bit faster. I already removed all of my unused plugins and increased stack space but it doesn't seem to make a lot of difference. Has anyone found a way of speeding up Intellij? |
- »»
Your computer must be very old, since on my 7-years-old Core 2 Duo E6600 the project with Egor's library compiles pretty fast, in about 5 seconds. The same speed is shown by my primitive types collections library (see in my blog). But I once tried to use Trove library and got 15-20 seconds, they have quite large code with lots of abstract classes, which slows down code generation. These numbers are for IDEA 13, maybe your IDE is too old?
- »»»
Hm I am not sure if that is the case. I am using a 2012 Macbook Pro Retina, with IDEA 14, with all updates I think. Before installing Egor's library I was getting something like that with around 5 seconds. But anyway thanks for the response, maybe there is some setting that I accidentally enabled or something. Also I am using Java 8, I don't know if that makes a difference. I forget exactly but maybe with Java 7 it was faster.
- »»
So just another thing I was wondering about is it fine to have the yaal library under the src folder? I would think that it does not make a difference, but just want to make sure that it does not force some additional recompile or something of the library. Just additional bit of information is that when say I compile topcoder task that does not call from the library (topcoder because codeforces always uses input/output from library) it takes about 1-2 seconds. However as soon as I call a method it can increase to as much as 20 seconds. Just wanted to make sure that this directory setup with the library and everything is the same way that everybody else is doing it. And also another question because I just noticed this but what does the number 4 by the Chelper project folder mean? Thanks!

archiveDirectory actually may not be in source, while it is not mandatory for outputDirectory to be a source one. Otherwise — sound advice
- »»»»»»
I have followed the advice above. I can generate some files using "Parse Contest" button, but:
- tests are not parsed (when I click Edit Tests, it's empty)
- Google Chrome plugin doesn't work (nothing happens when I open Codeforces page)
- also, when Main.java is generated, it doesn't contain implementation of the InputReader and OutputWriter (in the project settings, I've specified net.egork.chelper.util.InputReader and net.egork.chelper.util.OutputWriter). Instead, it contains this:
static class InputReader extends InputStream { InputReader; int read(); int readInt(); String readString(); } static class OutputWriter { OutputWriter; void print; void close(); }Any idea what I may be missing?
I use
- macOS Mojave Version 10.14.5
- IntelliJ IDEA 2019.1.3 (Community Edition)
- IDEA Plugin v4.4.2
- Google Chrome Version 75.0.3770.100 (Official Build) (64-bit)
- Chrome CHelper extension 4.4.3.1
- »»»»»»»»
OK, I kinda made it work by the following actions:
- Switched to Windows 10 instead of macOS
- I realized that the reason why InputReader and OutputWriter implementations were missing was that the plugin had nowhere to take the source code from. So, I downloaded the library fromhttps://github.com/EgorKulikov/yaal/tree/master/lib/main/net/egork and in the settings, changed net.egork.chelper.util.InputReader and net.egork.chelper.util.OutputWriter to net.egork.io.InputReader and net.egork.io.OutputWriter, respectively.
- Added IDEA to the firewall exceptions
Now:
- Main.java is generated and compiled successfully
- Competitive Companion chrome extension works (I didn't try CHelper extension on Windows)
- Tests are parsed when I add a task through the Chrome extension
However:
- Tests are not parsed when I add a task through "Parse Contest" button in IDEA
- I cannot find out how to generate JUnit tests. I have checked the "Enable Unit Tests" checkbox in the project settings and made sure Test directory is correct. But, nothing happens
- I would still love to make it work on Mac, so any advice is appreciated

Hey, I am facing the exact same issue. Can you elaborate a little more how to solve this issue?Waylesange Thanks
- »»»»»»
OK, just try to keep it simple. I suggest you update Intellij IDEA to the latest version. Secondly, you go to File -> Settings... -> Plugins and search for the chelper plugin. It is required to run the task run configurations, and it supplies you with the buttons on the toolbar, too. After you have done that, you should be getting the error about impossibility to find and load class from net.egork... Now you go to the jetbrains plugin site, search for chelper plugin there, and download the latest zip archive. After unzipping it, go to File -> Project Structure... -> Libraries -> + -> Java, select recursively the folder you just unzipped until you get to a bunch of jars that contain that missing class in the error. After you have added those jars to your classpath, along with JDK, it should be enough to parse a problem from codeforces site using Google Chrome plugin. Thus, you get the tests inherent to the problem as well, whereas if you are importing the problem from within Parse contest menu of chelper, you won't get the tests, which is sad and needs to be fixed by Egor Kulikov. I hope my experience helps you!

I don't think you need a video to do that. Let me give a brief explanation (assuming CHelper is already set up):
1. Install Competitive Companion
2. Restart Intellij IDEA
3. Open up the page of a problem
4. Click on Competitive Companion (the extension it should be a green plus)That should do it. Note that you don't have to repeat step 2 every time but it's important to do that upon installing Competitve Companion.
