How to get the entire project source code when write a customized rule

[teliu-ez]

I`m writing a custom rule for my project to find all unused properties as follows.

const useStyles = makeStyles({
  root: {
    overflow: "hidden",
    paddingTop: "20px",
  },
});

I use follow codes to get all properties:

module.exports = {
 rules: {
    "no-unused-message": {
      create: function (context) {
        return {
          'VariableDeclaration': function (node) {
            node.declarations.forEach(function (variableDeclarator) {
              if (variableDeclarator.init) {
                if (variableDeclarator.init.callee && variableDeclarator.init.callee.name == 'makeStyles') {
                  variableDeclarator.init.arguments[0].properties.forEach(function (p) {
                    const name = p.key.name
                  })
                }
              }
            })
          }
        };
      }
    }
  }
};

And then I want to search the whole project source code to find whether thess properties was used. But context.getSourceCode().getText() just return one file code. Is there a way to get whole project source codes

I’m sorry, ESLint does have a way to access other file’s code. It works only on one file at a time.
