{ // -------------------------------------------------------------------- // JSHint Configuration, Strict Edition // -------------------------------------------------------------------- // // This is a options template for JSHint[1], using JSHint example[2], // Ory Band's example[3], and haschek's example[4] as basis and setting // config values to be most strict: // // * set all enforcing options to true // * set all relaxing options to false // * set all environment options to false, except the browser value // * set all JSLint legacy options to false // // NOTE: Certain exceptions were made for my own use. Understand what each // deviation from what is described just above means for your project // // [1]: http://www.jshint.com/ // [2]: https://github.com/jshint/jshint/blob/master/examples/.jshintrc // [3]: https://github.com/oryband/dotfiles/blob/master/.jshintrc // // @author http://michael.haschke.biz/ // @author Michael Scheer // @license http://unlicense.org/ // // // ******************* // NOTE: Modifications have been made to the original script found at: // https://gist.github.com/haschek/2595796 // These modifications remove depreciated options and adding new // ones as of v2.8.0 // ******************* // // // == Enforcing Options =============================================== // // These options tell JSHint to be more strict towards your code. Use // them if you want to allow only a safe subset of JavaScript, very // useful when your codebase is shared with a big number of developers // with different skill levels. "bitwise" : true, // Prohibit bitwise operators (&, |, ^, etc.). "curly" : true, // Require { for every new block or scope. "eqeqeq" : true, // Require triple equals i.e. `===`. "es3" : false, // adhere to ECMAScript 3 specification -- Unneeded now and conflicts with promises "es5" : true, // enables syntax first defined in the ECMAScript 5.1 specification. "forin" : true, // Tolerate `for in` loops without `hasOwnPrototype`. "freeze" : true, // Prohibits overwriting prototypes of native objects such as Array, Date and so on. "funcscope" : false, // This option suppresses warnings about declaring variables inside of control structures while accessing them later from the outside. "futurehostile" : true, // This option enables warnings about the use of identifiers which are defined in future versions of JavaScript. "globals" : true, // "iterator" : false, // This option suppresses warnings about the __iterator__ property. This property is not supported by all browsers so use it carefully. "latedef" : true, // Prohibit variable use before definition. "maxcomplexity" : 10, // Lets you control cyclomatic complexity throughout your code "maxdepth" : 5, // Lets you control how nested do you want your blocks to be "maxerr" : 20, // Set the maximum amount of warnings JSHint will produce before giving up. Default is 50. "maxparams" : 4, // Set the max number of formal parameters allowed per function "maxstatements" : 50, // Set the max number of statements allowed per function: "noarg" : true, // Prohibit use of `arguments.caller` and `arguments.callee`. "nocomma" : true, // Prohibits the use of the comma operator. "nonbsp" : true, // Warns about "non-breaking whitespace" characters. "nonew" : true, // Prohibit use of constructors for side-effects. "notypeof" : false, // suppresses warnings about invalid typeof operator values. "shadow" : false, // suppresses warnings about variable shadowing "singleGroups" : true, // This option prohibits the use of the grouping operator when it is not strictly required. "strict" : true, // Require `use strict` pragma in every file. "undef" : true, // Prohibits the use of explicitly undeclared variables. "unused" : true, // warns when you define and never use your variables. "varstmt" : false, // the use of VariableStatements are forbidden // == Relaxing Options ================================================ // // These options allow you to suppress certain types of warnings. Use // them only if you are absolutely positive that you know what you are // doing. // ==================================================================== "asi" : false, // Tolerate Automatic Semicolon Insertion (no semicolons). "boss" : false, // Tolerate assignments inside if, for & while. Usually conditions & loops are for comparison, not assignments. "debug" : false, // Allow debugger statements e.g. browser breakpoints. "eqnull" : false, // Tolerate use of `== null`. "es5" : false, // Allow EcmaScript 5 syntax. "esnext" : true, // Allow ES.next specific features such as `const` and `let`. "evil" : false, // Tolerate use of `eval`. "expr" : false, // Tolerate `ExpressionStatement` as Programs. "funcscope" : false, // Tolerate declarations of variables inside of control structures while accessing them later from the outside. "globalstrict" : false, // Allow global "use strict" (also enables 'strict'). "iterator" : false, // Allow usage of __iterator__ property. "lastsemic" : false, // Tolerat missing semicolons when the it is omitted for the last statement in a one-line block. "loopfunc" : false, // Allow functions to be defined within loops. "onecase" : false, // Tolerate switches with just one case. "proto" : false, // Tolerate __proto__ property. This property is deprecated. "regexdash" : false, // Tolerate unescaped last dash i.e. `[-...]`. "scripturl" : false, // Tolerate script-targeted URLs. "smarttabs" : false, // Tolerate mixed tabs and spaces when the latter are used for alignmnent only. "shadow" : false, // Allows re-define variables later in code e.g. `var x=1; x=2;`. "supernew" : false, // Tolerate `new function () { ... ;` and `new Object;`. "validthis" : false, // Tolerate strict violations when the code is running in strict mode and you use this in a non-constructor function. // == Environments ==================================================== // // These options pre-define global variables that are exposed by // popular JavaScript libraries and runtime environments—such as // browser or node.js. // ==================================================================== "mocha" : true, // Mocha testing suite "browser" : true, // Standard browser globals e.g. `window`, `document`. "couch" : false, // Enable globals exposed by CouchDB. "devel" : false, // Allow development statements e.g. `console.log();`. "dojo" : false, // Enable globals exposed by Dojo Toolkit. "jquery" : false, // Enable globals exposed by jQuery JavaScript library. "mootools" : false, // Enable globals exposed by MooTools JavaScript framework. "node" : true, // Enable globals available when code is running inside of the NodeJS runtime environment. "nonstandard" : false, // Define non-standard but widely adopted globals such as escape and unescape. "prototypejs" : false, // Enable globals exposed by Prototype JavaScript framework. "rhino" : false, // Enable globals available when your code is running inside of the Rhino runtime environment. "wsh" : false, // Enable globals available when your code is running as a script for the Windows Script Host. // == Undocumented Options ============================================ // // While I've found these options in [example1][2] and [example2][3] // they are not described in the [JSHint Options documentation][4]. // // [4]: http://www.jshint.com/options/ // ==================================================================== "predef" : [ // Extra globals. //"exampleVar", //"anotherCoolGlobal", //"iLoveDouglas" ], "indent" : 4 // Specify indentation spacing }
