⚡ 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 (if file has compile command and file had changed) 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!

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
• Remove trailing newlines for fold to work (folding is optional via settings)

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
