configurations

grep2json.config.js in process currend directory can change the outout.

You can get grep2json.config.js with the below line

npx gren2json --init-config

configuration example

module.exports = {
  prepareStore: async () => await Promise.resolve({}),
  setupResult: async (block, structuredLine, store) => {
    return await Promise.resolve({
      fileName: structuredLine.fileName,
      matchedLineNumber: structuredLine.lineNumber,
      line: structuredLine.codeLine
    });
  }
};

prepareStore()

prepareStore() in grep2json.config.js will be executed once before setupResult().

prepareStore() should return a Promise that resolves as any object.

setupResult()

setupResult() in grep2json.config.js will be executed with each matched line.

setupResult() should return a Promise that resolves as any object.

setupResult() receives block, line, and store as the parameters.
