⚡ Fast Olympic Coding ⚡

Fast Olympic Coding is an extension to assist with various tasks in competitive programming. It is a ported and enhanced version of the corresponding Sublime Text plugin that also leverages the power of VSCode.

⚡ Overview

• 📜 Concurrently run, edit, and delete multiple testcases
• 👨🏻‍💻 Stress tester to find counterexamples
• 👜 Insert pre-written code from another file with automatic folding
• 🛜 Reads contests and problems from Competitive Companion
• 🏃 BLAZINGLY FAST! Asynchronous design + optimizations = 99% spam proof!

💻 Keybinds

• Compile: Ctrl+Alt+C
• Compile and run all testcases: Ctrl+Alt+B
• Stop all testcases: Ctrl+Alt+K
• Delete all testcases: Ctrl+Alt+D
• Run stress test: Ctrl+Alt+G
• Insert file template: Ctrl+Alt+I

📥 Install within VSCode or at Visual Studio Marketplace

</> Setting Up

Provide run settings for the languages you use in settings.json. Here are some examples for C++, Python, and Java:

{
  "fastolympiccoding.runSettings": {
    ".cpp": {
      "compileCommand": "g++ -std=gnu++20 -D_GLIBCXX_DEBUG ${path:${file}} -o ${path:${fileDirname}/${fileBasenameNoExtension}${exeExtname}}",
      "runCommand": "${path:${fileDirname}/${fileBasenameNoExtension}${exeExtname}}"
    },
    ".py": {
      "runCommand": "python ${path:${file}}"
    },
    ".java": {
      "compileCommand": "javac ${path:${file}}",
      "runCommand": "java -cp ${fileDirname} ${fileBasenameNoExtension}"
    }
  }
}

We can use the following variables in the syntax of ${...}

• Most of VSCode's built-in variables
• ${exeExtname} returns .exe for Windows and an empty string for other platforms
• ${path:*value*} normalizes *value* into a valid path string for the current platform

Settings per language

• compileCommand (optional): Command to run before runCommand when the file content changed
• runCommand: Command to run the solution
• currentWorkingDirectory (optional): sets the current working directory for runCommand

📜 Testcase Window

📄 Other features include...

• Show/hide the testcase details
• Shortened details of testcases for huge outputs
  • View full text by clicking on their corresponding arrows
• Color supported output for compile errors
• ... and so much more!

View wrong answers in a diff view!

General setting for both Testcase Window and Stress Tester

• font: Font family used to render text (restart extension to apply)
• runSettings: Object of run settings
• maxDisplayCharacters: Maximum number of characters to display for each output
• maxDisplayLines: Maximum number of lines to display for each output

👨🏻‍💻 Stress Tester

Required files (naming scheme can be configured in settings):

• <name>.[ext]: the solution to bruteforce against

• <name>__Good.[ext]: the solution that outputs the correct answer

• <name>__Generator.[ext]: to generate inputs for the other 2 files

  • The extension provides a 64-bit integer seed input for random number generators!

• 💡TIP: To stress test for Runtime Error instead of Wrong Answer, have the good solution be the same as the one to bruteforce against!

Stress Tester was able to find an counterexample due to an integer overflow bug!

Settings for Stress Tester

• goodSolutionFile: Full path for good solution file (supports ${...})
• generatorFile: Full path for generator file (supports ${...})
• delayBetweenTestcases: Amount of delay between generated testcases in milliseconds (minimum: 5)
• maxRuntime: Maximum time in milliseconds the Stress Tester is allowed to spend on one testcase (-1 for no limit)

---

👜 Inserting Prewritten Code

• Add the root directory of the templates to the settings
• NOTE: Remove trailing newlines for fold to work (folding is optional via settings)
  • Folding depends on VSCode support, which may require other extensions depending on the language.

Adding a tree reroot DP template without switching files

Possible settings

• fileTemplatesBaseDirectory: Full path to the base directory of all prewritten files (supports ${...})
• foldFileTemplate (default: false): Whether to fold the newly inserted prewritten code

---

🛜 Competitive Companion

• Open the extension to start the listening process!

Using Competitive Companion to parse a CodeForces problem

We can parse an entire CodeForces Div.3 Contest!

Settings for Competitive Companion integration

• openSelectedFiles (default: true): Whether to open all the selected files
• askForWhichFile (default: false): Ask for which file to write testcase onto, even when a file is currently opened and only a single problem has been received
• includePattern (default: **/*): Glob pattern to filter in the included files for asking prompt
• excludePattern (default: empty): Glob pattern to filter out the included files for asking prompt
