/*
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 Konfabulator text.
The second parameter is an optional object of options which control the
operation of JSLINT. Most of the options are booleans: They are all are
optional and have a default value of false.
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 members:
{
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 fatal error was found, a null will be the last element of the
JSLINT.errors array.
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(limited);
If limited is true, then the report will be limited to only errors.
You can request a data structure which contains JSLint's results.
var myData = JSLINT.data();
It returns a structure with this form:
{
errors: [
{
line: NUMBER,
character: NUMBER,
reason: STRING,
evidence: STRING
}
],
functions: [
name: STRING,
line: NUMBER,
last: NUMBER,

member: {

}
],
implieds: [

line: NUMBER
}
],
urls: [

],
json: BOOLEAN
}
Empty arrays will not be included.
