A Visual Studio Code Extension to help Codeforces Users Code with Convenience. This extension is specially for people who want to save time in a live codeforces contest and upsolve problems comfortably. This extension responds quickly to users. It can swiftly filter through the problem list by specifying tags and ratings, create folders for contests and problems containing sample tests of each problem in them and compile and run tests automatically. For added convenience we've created buttons to directly open problem statements and submission pages on the default browser.
Enter Handle in settings and view problems, contests and profile with submission status on each problem
Create Problem/Contest Folders inclusive of all sample tests, compile and run automatically, get comprehensive verdicts and view problem statement and submission webpages.
- View Complete ProblemSet List along with their associated tags and ratings.
- Swiftly Filter through the ProblemSet by specifying Ratings and Tags.
- View Currently running, Upcoming and all Past contests and also view the precise start date, time and duration of upcoming contests.
- Fast Folder Creation on a single click for Contests from the Codeforces contest list and Problems from the Codeforces problem list.
- Folder for a contest contains a folder for each problem and also contain all sample test cases and program files for each problem.
- Folder for a problem consists of all its sample test cases and a program file loaded with a template whose path may be specified in the settings.
- Add additional tests to any problem.
- Compile and run any program file against the testcases and get comprehensive results.
- Open problem statement or submission page with a single click, on your default browser. (You must be logged into codeforces before hand to open the submission page successfully)
- Compiler may be selected and compilation flags can be set through the codepal settings.
- Perform Stress testing to find a counter test case for your code.
- Get a personalized experience of viewing details of your Codeforces profile and the status of problem submissions made, by entering your Codeforces handle in the codepal settings.
- C++ (compiler : g++)
- C (compiler : gcc)
- Java (compiler : javac)

- Add the lower bound for problem’s rating. (Default lower bound is 0)
- Add the upper bound for problem’s rating. (Default upper bound is 4000)
- Tick the tags you want for the problems. (If no tags are selected, no tag-based filtering is done)
- Click on icon 6 (shown here) beside the problem name to create and open a problem folder containing the solution file and test cases. (Make sure you have opened a folder on VS Code where you want the problem folder)
- Click on the type of contest you want to participate in. (Past, Running or Future)
- Precise timings and durations of upcoming contests are also shown.
- Click on icon 3 (shown here) beside the contest name to create and open a contest folder containing the problems folders of each problem of the contest. (Make sure you have opened a folder on VS Code where you want the contest folder)
- Press Ctrl + comma(,) or go to settings of VS Code (icon on bottom left).
- Go to extensions and select codepal, and add your template file path to the given space
- Press Ctrl + comma(,) or go to settings of VS Code (icon on bottom left).
- Go to extensions and select codepal, and choose the compiler you want from the drop down list.
- Click on icon 7 (shown here) on the top right side of the editor window, or press Ctrl + Alt + A, to add manual test cases for the problem.
- Click on icon 10 (shown here) on the top right side of the editor window, or press Ctrl + Alt + R, to run the code for all sample and manual test cases.
- Click on icon 9 (shown here) on the top right side of the editor window, or press Ctrl + Alt + O, to open the problem statement on Codeforces in your default browser.
- Click on icon 12 (shown here) on the top right side of the editor window, or press Ctrl + Alt + S, to open the submission page of the problem on Codeforces in your default browser.
- Click on icon 8 (shown here) on the top right side of the editor window to create the stress testing files called "brute" and "gen". Here "brute" is the code that is a bruteforce solution or any code that gives the correct output and "gen" is the generator file that makes testcases. You need to code both of them.
- Command line arguments of integers (1,2,3...) are passed to the generator file so as to keep a fixed random seed each time you stress test. A template is initially provided that takes care of this.
- Once all 3 files compile properly (solution, "brute" and "gen" files) click on icon 11 (shown here), or press Ctrl + Alt + Z, to stress test. It will run the "gen" file to create input and compare it against your solution and "brute". If they differ then it is reported else it moves to the next case. By defualt it will run for a number of 100 test cases but this can be changed in the settings.
- Stress testing can be forced to stop on pressing Ctrl + Shift + Z.
- Press Ctrl + comma(,) or go to settings of VS Code (icon on bottom left).
- Go to extensions and select codepal, and add your Codeforces handle to get a personalized experience of the extension.
- On entering your handle, you will be able to view your profile details in the User Profile section of the side bar.
- This will also enable you to view the status of problem submissions made on Codeforces, through ticks or crosses against the problem names, denoting whether the submission was accepted or failed.
