Console output from transforms is silently swallowed about jscodeshift

[DrewML]

Not sure if something changed in the codebase that enabled this, but this works with the current version of jscodeshift. Verified with the following transform:

export default function transformer(file, api) {
    console.log('heyyyyyyy');
    return null;
};

Mmh, not sure. According to the docs, child_process.fork() should forward everything to the parent's stdout by default.

However, even if it worked, I'm not sure it would be useful, since the workers run concurrently and any output produced by the child processes might be intermingled with the output of the parent process.

Have you considered using the stats function instead? It Only works in in dry runs, but lets you output valuably information.

Yep, works fine for me too.

This does not shows everything though:

module.exports = function (file, api) {
  const j = api.jscodeshift;
  const { statement } = j.template;
  console.log("Starting"); // this is shown
  return j(file.source)
    .find(j.FunctionExpression)
    .replaceWith((p) => {
      console.log("What the", p); // not logged
      const root = j(p.value);
      const variablesToReplace = {};
      return p;
    });
};

sorry, my bad, I was using FunctionExpression to look for ArrowFunctionExpressions. It works.
