// --------------------------------------------------------------------
// JSHint Configuration
// --------------------------------------------------------------------
//
// Derived from
// https://raw.github.com/gist/2595796/500806cafd239ace8dc94c998a8d4f7270947b12/.jshintrc
// == 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.).
"camelcase" : true,
"curly" : true, // Require {} for every new block or scope.
"eqeqeq" : true, // Require triple equals i.e. `===`.
"es3" : true,
"forin" : false, // Tolerate `for in` loops without `hasOwnPrototype`.
// We can use !function()(); which has a very clear warning aspect
"immed" : false, // Require immediate invocations to be wrapped in parens e.g. `( function(){}() );`
"indent" : 2, // Specify indentation spacing
"latedef" : true, // Prohibit variable use before definition.
"newcap" : true, // Require capitalization of all constructor functions e.g. `new F()`.
"noarg" : true, // Prohibit use of `arguments.caller` and `arguments.callee`.
"noempty" : true, // Prohibit use of empty blocks.
"nonew" : true, // Prohibit use of constructors for side-effects.
// Just for this case: while(l--){}
"plusplus" : false, // Prohibit use of `++` & `--`.
"quotmark" : "single",
"undef" : true, // Require all non-global variables be declared before they are used.
"unused" : true, // Warns for undefined vars
// I like my dot
"regexp" : false, // Prohibit `.` and `[^...]` in regular expressions.
// False, but should probably be true
"strict" : true, // Require `use strict` pragma in every file.
"trailing" : true, // Prohibit trailing whitespaces.
// New complexity checking: Use with caution.
// The max are pretty high but should be reduced as time goes on
"maxparams" : 4, // Max number of formal parameters allowed per function
"maxdepth" : 2, // How much nesting is acceptable
// I wish we'd have an independent count for module functions
"maxstatements" : 25, // Max number of statements pallowed per function
// See: http://en.wikipedia.org/wiki/Cyclomatic_complexity#Limiting_complexity_during_development
// I have no clue how this will behave but we may relax it later
"maxcomplexity" : 10, // Allowed cyclomatic complexity
// == 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.
// Allow it because it's already in use and would require checking for undefined and other falsy
"eqnull" : true, // Tolerate use of `== null`.
"esnext" : false, // Allow ES.next specific features such as `const` and `let`.
"evil" : false, // Tolerate use of `eval`.
// Allows code like ;fnDefined && fnDefined();
"expr" : true, // 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.
// Allows operators and punctuation to be place in front
"laxbreak" : true, // Tolerate unsafe line breaks e.g. `return [\n] x` without semicolons.
// Comma in front is very neat
"laxcomma" : false, // Suppress warnings about comma-first coding style.
"loopfunc" : false, // Allow functions to be defined within loops.
"multistr" : false, // Tolerate multi-line strings.
"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.
// Reduce the complexity of a lot of functions
"shadow" : true, // 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;`.
// == Environments ====================================================
//
// These options pre-define global variables that are exposed by
// popular JavaScript libraries and runtime environments—such as
// browser or node.js.
"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.
// We use jQuery
"jquery" : true, // 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.
// Put it to true in an infile comment if you write rhino scripts
"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.
// == 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.
// _varname is really ugly and doesn't mean I won't change the var but it's not THAT important
"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/
// Your choice although build machine should probably have a limit
// "maxerr" : 100, // Maximum errors before stopping.
// Extra globals.
