// WARNING: JSLint will hurt your feelings.
|
|
|
|
// JSLINT is a global function. It takes two parameters.
|
|
|
|
// var myResult = JSLINT(source, option);
|
|
|
|
// The first parameter is either a string or an array of strings. If it is a
|
|
// string, it will be split on '\n' or '\r'. If it is an array of strings, it
|
|
// is assumed that each string represents one line. The source can be a
|
|
// JavaScript text, or HTML text, or a JSON text, or a CSS text.
|
|
|
|
// The second parameter is an optional object of options that control the
|
|
// operation of JSLINT. Most of the options are booleans: They are all
|
|
// optional and have a default value of false. One of the options, predef,
|
|
// can be an array of names, which will be used to declare global variables,
|
|
// or an object whose keys are used as global names, with a boolean value
|
|
// that determines if they are assignable.
|
|
|
|
// If it checks out, JSLINT returns true. Otherwise, it returns false.
|
|
|
|
// If false, you can inspect JSLINT.errors to find out the problems.
|
|
// JSLINT.errors is an array of objects containing these properties:
|
|
|
|
// {
|
|
// line : The line (relative to 0) at which the lint was found
|
|
// character : The character (relative to 0) at which the lint was found
|
|
// reason : The problem
|
|
// evidence : The text line in which the problem occurred
|
|
// raw : The raw message before the details were inserted
|
|
// a : The first detail
|
|
// b : The second detail
|
|
// c : The third detail
|
|
// d : The fourth detail
|
|
// }
|
|
|
|
// If a stopping error was found, a null will be the last element of the
|
|
// JSLINT.errors array. A stopping error means that JSLint was not confident
|
|
// enough to continue. It does not necessarily mean that the error was
|
|
// especially heinous.
|
|
|
|
// You can request a Function Report, which shows all of the functions
|
|
// and the parameters and vars that they use. This can be used to find
|
|
// implied global variables and other problems. The report is in HTML and
|
|
// can be inserted in an HTML <body>.
|
|
|
|
// var myReport = JSLINT.report(errors_only);
|
|
|
|
// If errors_only is true, then the report will be limited to only errors.
|
|
|
|
// You can request a data structure that contains JSLint's results.
|
|
|
|
// var myData = JSLINT.data();
|
|
|
|
// It returns a structure with this form:
|
|
|
|
// {
|
|
// errors: [
|
|
// {
|
|
// line: NUMBER,
|
|

// You can obtain the parse tree that JSLint constructed while parsing. The

// with

// JSON.stringify(JSLINT.tree, [

|
|
|
|
// JSLint provides three directives. They look like slashstar comments, and
|
|
// allow for setting options, declaring global variables, and establishing a
|
|
// set of allowed property names.
|
|
|
|
// These directives respect function scope.
|
|
|
|
// The jslint directive is a special comment that can set one or more options.
|
|
// The current option set is
|
|
|
|
// adsafe true, if ADsafe rules should be enforced

|
// maxerr the maximum number of errors to allow

|
// maxlen the maximum length of a source line
|
|
// newcap true, if constructor names capitalization is ignored

|
// node true, if Node.js globals should be predefined

|
// nomen true, if names may have dangling _
|
|
// on true, if HTML event handlers should be allowed
|
|
// passfail true, if the scan should stop on first error
|
|
// plusplus true, if increment/decrement should be allowed
|
|
// properties true, if all property names must be declared with /*properties*/
|
|
// regexp true, if the . should be allowed in regexp literals
|
|
// rhino true, if the Rhino environment globals should be predefined

|
|
|
// The properties directive declares an exclusive list of property names.
