Compe.js

A CLIxLibrary for Competitive Programming with JavaScript/Node.js

Requirements

• Node v12.x or higher (preferably v16.x+)
• Set node modules to path variable to use cli

Installation

For the package:

npm i compe

For the cli, you can:

npm i -g compe minify

You can add the prefix npx after every command as an alternative where you want to avoid installing global package. Enable intellisense to get the best experience.

Compe commands

Add npx prefix incase you don't have CLIs installed.

$ compe i <source-file.js> <input-file.txt>: Initialize the source file at source-file.js and the input file at input-file.txt (if input-file is empty then the default is 'input.txt')
$ compe s <source-file.js>: Save the source file directory as default
$ compe i s <source-file.js> <input-file.txt>: Initialize the file and then save to config
$ compe r <source-file.js>: If the config has default source file, source-file can be ignored. Run the source file and build it at source-file-build.js and fully compressed to submit on Online Judges at source-file-comp.js

Getting your first AC

Make a txt (by default from template, it is "input.txt") file in the same directory with the one you want to run for stdin. The main function takes in rd and wr as a function to read and write. Sample code for printing sum of an array at demo.js after init:

const {
  Reader, proc,                                     // IO & Processor
  multiArray, vectorArray,                          // Fast array generators
  TreeSet, Deque, DisjointSetUnion, PriorityQueue,  // Data structures
  Graph, dfs, bfs, minimumSpanningTree, dijkstra    // Graph Algorithms
} = require('compe');
// DO NOT EDIT THIS LINE //
function main(rl, wr) {
  let rd = new Reader(rl);
  // write your code from here
  let x = rd.readArray();
  let sum = 0;
  for (let y of x) {
    sum += y;
  }
  wr(y);
}
proc(main, 'input.txt');
