Remove the `/* eslint-disable */` comment at file header, for changed files on branch

README.MD

When you try to add eslint to a large project, you better try this approach as in this script.

Now, you want to enforce your team members to actually remove the /* eslint-disable */ comment at file header, for all files that they've changed.

Here you go.

remove-eslint-disable.js

const proc = require('child_process');
const fs = require('fs');

const run = command => proc.execSync(command, {encoding: 'utf8'}).trim();

const getChangedFiles = () => run('git diff --name-only master').split('\n');

const removeFirstLine = data => data.split('\n').slice(1).join('\n');

function stripDisableString(file) {
    const content = fs.readFileSync(file, 'utf8');
    if (content.startsWith('/* eslint-disable */')) {
        fs.writeFileSync(file, removeFirstLine(content), 'utf8');
    }
}

getChangedFiles().forEach(stripDisableString);
