JSON formatter "source" attribute should focus on relevant lines

Tell us about your environment

• ESLint Version: 5.12.0
• Node Version: 11.9.0
• npm Version: 6.5.0

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

/**
 * Save a file to a specific location and create required directories
 * @param {string} filePath path to file relative to main directory
 * @param {string} data file contents
 */
function writeFileCreateDirs (filePath, data) {
  fs.mkdirpSync(path.dirname(filePath))
  fs.writeFileSync(filePath, data)
}

node_modules/.bin/eslint --format=json -o=eslint_result.json cache.js

What did you expect to happen? I want an understandable and short JSON formatted output.

What actually happened? Please include the actual, raw output from ESLint. In the eslint_result.json I have this content when I console.log it:

I think it will much more useful if every single issue contains its JSON attribute called “filePath” and in the source attribute is not the whole file but instead the problematic line or problematic block.

Are you willing to submit a pull request to fix this bug?

Yes, but maybe I will need help.

As this is a question rather than an action item, I’m closing the issue. If you still need help, please send a message to our mailing list or chatroom. Thanks!

Okay, thanks for the information. I will investigate those options.
