Mercury

Mercury is a bot for handling in-code static translations. Developed at OpenTable, it takes care of dozens of codebases by making automated Pull Requests to keep the code up to date with our translations.

How Mercury works

The bot looks for a mercury.json manifest file in a repository's root. It then locates the source files and keeps them updated with Smartling by using its API and making Pull Requests. Please refer to the Mercury consumer integration runbook and FAQ.

How to setup the bot in your organization

Mercury is available as npm module and needs to be configured to run with github and smartling API tokens.

Here is a code example:

const mercury = require('mercury-bot');

const config = {
  github: {
    apiTokens: [
      { operation: 'read', value: 'token-1234567890' },
      { operation: 'write', value: 'token-0987654321' }
    ],
    owner: 'mercurybot',
    branch: 'mercury'
  },
  smartling: {
    userIdentifier: 'userId-1234567890',
    userSecret: 'userSecret-0987654321'
  },
  repositories: {
    'github-org': ['repo1', 'repo2']
  }
};

const app = mercury({ config });

// Optional event handlers
app.on('error', console.log);
app.on('action', console.log);
app.on('result', console.log);

// Run
app.run(() => process.exit(0));
