Very naive Atom script to convert string concatenation to EcmaScript 6 template literals - for fixing ESLint 'prefer-template' rules

toLiteral.js

function toLiteral() {
    var t = atom.workspace.getActiveTextEditor().getSelectedText();

    t = t.replace(/\' \+ /g, "${");
    t = t.replace(/ \+ \'/g, "}");

    if (t.indexOf("'") == 0) {
        t = t.substring(1);
    } else {
        t = "${" + t;
    }

    if (t.substr(t.length - 1, 1) == "'") {
        t = t.substr(0, t.length - 1);
    } else {
        t = t + "}";
    }

    atom.workspace.getActiveTextEditor().insertText("`" + t + "`");
}
