What was the key to speedup, if it's not a secret?

        Long answer is previously I added everything that was imported from task class and everything in the same package, then everything that is imported from those classes and so on, and then removing unused code which is slow and cyclic references may remain. Now I only add what is actually referenced. Among other things now you can reference classes by fqn instead of importing them. Moreover naming conflict would be handled by constructing other names for classes

          Strange, it's not working for me. I just get the "Nothing to show" message in the problem list. I already hit the "Refresh" button a few times and waited for a few minutes. The other judges work OK. Any hints?

          I have IDEA 14, CHelper 4.0.1, running in Fedora 20 with Oracle JDK, in case it helps.

Hello,

I recently tried to run TopCoder on C-Helper. However, when I try to run in Intellij Idea, it gives me an null pointer exception, and I can't compile it on Topcoder Arena. Is there anything I have to install other than CHelper and Arena? There error I've got in Idea is:

Can you change archive directory's structure to something simple like this:

Codeforce

  • Round 300

Egor — Unfortunately, I've had some trouble using the parser. You can see my directory and my settings here:

When I attempt to parse a contest, I'm met with the "Nothing to show" screen found here:

When I try to parse an individual problem using the Chrome extension, I see the circle animation on Chrome, but nothing happens on IDEA. (IDEA is open and the project is loaded.)

Do you have any idea what could cause this issue? Many thanks for any response.

    Well, not being aboe to parse from idea seems like idea do not have access to internet. Not being able to parse with chrome is likely something to do with idea not able to connect on localhost port. Do idea runs in some kind of sandbox?

      That sounds like a likely cause of the issue. IDEA is running on a basic Windows installation. I've tweaked the firewall a bit but haven't had any luck there. Any ideas about what could be causing the issue? Is it possible that the wi-fi configuration is at fault?

      Thanks for the assistance!

      Just posting a quick reminder since it's been a couple days since last response. No worries if we can't figure it out, but any thoughts you could provide would be much appreciated. I tested it on a different computer without the same firewall software, so I have to imagine that it's somehow related to the wi-fi.

      Thanks for any assistance!

          For anyone else with the same issue, I managed to fix it by updating IntelliJ to the latest version. I searched around and found some errors related to an IntelliJ TransactionGuard class, and in case the class was broken, I updated IntelliJ, after which the program worked.

          Many thanks for your assistance and for creating the plugin.

I see there's an option to parse entire contest in Idea plugin, but the Chrome extension seems to activate only on a single problem page. Am I missing something or the extension doesn't support contest parsing? That looks weird.

    Chrome parser only works with single page so it just can't parse whole contest at once. One exception is Google Code Jam because all problems presented in what is basically single page

One more question — Is it possible to use stress testing with CHelper (writing an algorithm to automatically generate small test cases and their correct answers and printing the first one for which the main algorithm fails)? Also, is there any way to modify the template for the output class? I've checked through all of the templates in the project and haven't been able to find it. (It's given me a few issues with some online judges, most notably the USACO training pages.)

    It is possible to stress test. If you look in task properties there is "Test class" if you push Advanced

    It is possible to use whatever output class you want as long as it has close method. You just need to update preferences

I'm trying to use your parsers, and class Task raises some questions. It contains all necessary information about the problem except time and memory limit, while they are usually very easily parsed. On the other hand, it contains your plugin-specific data like mainClass, truncate, includeLocale etc.

Did you think about extracting the parsers into a separate library with more general interface, independent of the plugin implementation?

    Memory limit is actually parsed and put into VM arguments

Hey Egor, now that this post is back to business, is it possible to have a feature where we can submit directly from the IntelliJ. That is we dont have to go back to the problem page, browse for our solution and get the result. The plugin would do all of this for me and return me the status of the solution. Even if you could do this for codeforces (because nowadays I just participate here), that would be great :)

Thank you for the new Code Jam parser! Are you planning to support parsing of the whole contest at once?

    Previously I parsed everything at once because web page actually had all the problems. New web page only has single problem statement

The link in section 4.2.2 https://plugins.jetbrains.com/plugins/beta/list is broken, it redirects me to https://plugins.jetbrains.com/plugins/list?channel=beta&pr_productId=.

    It is not a link, it is repository you need to add to idea plugin repositories in order to use beta versions of CHelper

Can you add parse task for old GCJ system too?

As Google Kickstart uses the same interface as of old GCJ system. Due to plugin update, I am unable to parse task in Kickstart :(

    I had not removed support, you should still be able to parse from old system with Chrome extension

What's the limitation of CHelper's inlining abilities. Can pull data structures from say, google common collections/gauva?

      I couldn't get it to work with gauva. Anything special I need to do? It doesn't inline all the classes needed to MultiHashMap work.

            Seems like annotations are the cause of problem. Next beta version removes all annotations just to be on the safe side

            But multiset add about 800 lines and 30 kilobytes of code, so use resposibly

Test cases were not parsed in contest 1028 and 1029 but they are if I pick one task from the problem set (in particular task 1029F). I use IntelliJ IDEA 2018.2.1 and CHelper 4.4.2 on Ubuntu 16.04.

Is it a known issue? Any workaround/fix?

Hey Egor, have you thought of updating plugin after recent changes in AtCoder platform. It will be very helpful. As now task are not being parsed after UI improvements.

    I am a bit occupied with work/other projects atm. You can try Competitive Companion Chrome extension for parsing tasks

Are you going to update the source code on github with new parsers?

Hi Egor, after i create task with 4.4.3b3, I could not see the task.json. And I see this error not long after i created task:

Hi I installed the plugin through Intellij marketplace. But i'm unable to build any task. Error: Error: Could not find or load main class net.egork.chelper.tester.NewTester Caused by: java.lang.ClassNotFoundException: net.egork.chelper.tester.NewTester

Did anyone else see it? Is there any setup instructions that I missed?

Also, when trying to run topcoder arena by clicking on the topcoder icon in the plugin toolbar, i get an error 'javaws' file not found. Have tried several things with no luck.

Using Intellij Community 2020.1

    Yes. I am getting the same error (Error: Could not find or load main class net.egork.chelper.tester.NewTeste). Could Egor please look into this?

    EDIT: The issue has been fixed. See here for a complete fix.

When I don't use a task and just let it sit there, the configuration for the task is set to build the project multiple times before launching. This clearly is unnecessary and slows running the task by a lot (due to the excessive build time). Is there any fix for this (without having to archive the task)?

Hi Egor,

I have made the chelper IDE configurations gradle-based, so that I could easily change laptops and wouldn't need too much Intellij configuration of the plugin (other than installing the plugin). My build.gradle dependencies sections looks like this:

dependencies {
    // CHelper dependencies
    implementation files('libs/chelper.jar')
    implementation files('libs/cojac.jar')
    implementation 'commons-lang:commons-lang:2.6'
    implementation 'org.json:json:20180130'
    implementation 'com.fasterxml.jackson.core:jackson-core:2.7.4'
    implementation 'com.fasterxml.jackson.core:jackson-annotations:2.7.0'
    implementation 'com.fasterxml.jackson.core:jackson-databind:2.7.4'

    // other stuff
}

Two of the dependencies are not versioned and I guess don't have Maven coordinates — (cojac.jar and chelper.jar).

While running the Task, I get a bunch of errors (seemingly, related to cojac.jar) and are too much and annoying. In the end, the tests are run fine, however those errors take up all the output, sometimes hard to find the real, useful outputs.
