Support "ignorePath" as top level configuration setting

[medikoo]

Currently the only way to use alternate ignore file is to pass --ignore-path into CLI, and that's quite limited as it doesn't ensure that desired ignore file is respected by default in every lint check for given project.

That affects IDE configurations. e.g. on my side in most of the projects I want ESLint by default to treat .gitignore as ignore file, for that I have lint scripts configured as eslint --ignore-file=.gitignore ., but that's not picked by VSCode ESLint extension, which anyway doesn't want to lint files that start with a . which are otherwise linted by lint scripts.

Thank you for your request.

You can do like below:

// .eslintrc.js
const fs = require("fs")

module.exports = {
    ignorePatterns: fs.readFileSync(".gitignore", "utf8").split("\n").filter(Boolean),
    // other settings.
}

@mysticatea thanks, that indeed works as workaround. Still it'll be nice to be able to achieve without a need of JS file configuration or copying a settings

Please add this. The workaround above is incompatible with .eslintrc.json modules.

To close the loop here: we aren't making any further changes to the configuration system. We are working on a new configuration system (defined in eslint/rfcs#9) and there will be more options for specifying ignore files.
