Some fixes, working on corr challenges

[vchess.git] / client / src / data / challengeCheck.js

import { extractTime } from "@/utils/timeControl";

export function checkChallenge(c)
{
	const vid = parseInt(c.vid);
	if (isNaN(vid) || vid <= 0)
		return "Please select a variant";

  const tc = extractTime(c.timeControl);
  if (!tc)
    return "Wrong time control";

	// Basic alphanumeric check for opponent name
	if (!!c.to)
	{
     // TODO: slightly redundant (see data/userCheck.js)
		if (!c.to.match(/^[\w]+$/))
			return "Wrong characters in opponent name";
	}

  // Allow custom FEN (and check it) only for individual challenges
  if (c.fen.length > 0 && !!c.to)
  {
    if (!V.IsGoodFen(c.fen))
      return "Bad FEN string";
  }
  else
    c.fen = "";
