{ // -------------------------------------------------------------------- // JSHint Configuration // -------------------------------------------------------------------- // // @author Chad Engler // == 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" : false, // Disallow bitwise operators (&, |, ^, etc.). "camelcase" : true, // Force all variable names to use either camelCase or UPPER_CASE. "curly" : false, // Require {} for every new block or scope. "eqeqeq" : true, // Require triple equals i.e. `===`. "es3" : false, // Enforce conforming to ECMAScript 3. "forin" : false, // Disallow `for in` loops without `hasOwnPrototype`. "immed" : true, // Require immediate invocations to be wrapped in parens e.g. `( function(){}() );` "indent" : 4, // Require that 4 spaces are used for indentation. "latedef" : true, // Prohibit variable use before definition. "newcap" : true, // Require capitalization of all constructor functions e.g. `new F()`.

"undef" : true, // Require all non-global variables be declared before they are used. "unused" : true, // Warn when varaibles are created by not used. "strict" : false, // Require `use strict` pragma in every file. "trailing" : true, // Prohibit trailing whitespaces. "maxparams" : 6, // Prohibit having more than X number of params in a function. "maxdepth" : 6, // Prohibit nested blocks from going more than X levels deep. "maxstatements" : false, // Restrict the number of statements in a function. "maxcomplexity" : false, // Restrict the cyclomatic complexity of the code. "maxlen" : 120, // Require that all lines are 100 characters or less. "predef" : [ // Register predefined globals used throughout the code. // Predef Mocha BDD interface "describe", "it", "before", "beforeEach", "after", "afterEach" ], // == 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`. "esnext" : false, // 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, // Tolerate missing semicolons when the it is omitted for the last statement in a one-line block. "laxbreak" : false, // Tolerate unsafe line breaks e.g. `return [\n] x` without semicolons. "laxcomma" : false, // Suppress warnings about comma-first coding style. "loopfunc" : false, // Allow functions to be defined within loops. "moz" : false, // Code that uses Mozilla JS extensions will set this to true "multistr" : false, // Tolerate multi-line strings. "proto" : false, // Tolerate __proto__ property. This property is deprecated. "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;`. "sub" : false, // Tolerate all forms of subscript notation besides dot notation e.g. `dict['key']` instead of `dict.key`. "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. "browser" : false, // 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. "worker" : false, // Enable globals available when your code is running as a WebWorker. "wsh" : false, // Enable globals available when your code is running as a script for the Windows Script Host. "yui" : false, // Enable globals exposed by YUI library. // == JSLint Legacy =================================================== // // These options are legacy from JSLint. Aside from bug fixes they will // not be improved in any way and might be removed at any point. "nomen" : false, // Prohibit use of initial or trailing underbars in names. "onevar" : false, // Allow only one `var` statement per function. "passfail" : false, // Stop on first error. "white" : false, // Check against strict whitespace and indentation rules. // == 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/ "maxerr" : 100 // Maximum errors before stopping. }
