\fIUsing JSLint with a config file\fR
.P
  Start with the included example jslintrc file and customize your options per project
  or copy it to $HOME/\.jslintrc to apply your setting globally
.P
##INSTALLATION
.P
To install jslint globally, use
 npm install jslint \-g
.P
To install jslint locally, use
 npm install jslint
.P
When installed locally, jslint can be run as
 \./node_modules/\.bin/jslint
.P
##FILES
.P
jslint looks for the following config files at startup:
.P
 $HOME/\.jslintrc
 \./jslintrc
 \./\.jslintrc
.P
The format of a jslint options file is a JSON file containing a single object
where the keys are jslint option names and the values are the option argument;
use \fBtrue\fP to enable and \fBfalse\fP to disable boolean options\.  An example of a
valid option file is:
.P
 {
   "vars": true,
   "white": true,
   "maxlen": 100,
   "predef": "foo,bar,baz"
 }
.P
Comments are not allowed in option files\.
.P
##PRECEDENCE
.P
The order of precedence for options is as follows:
.RS 0
.IP 1. 3
in the $HOME/\.jslintrc
.IP 2. 3
in \./jslintrc or \./\.jslintrc
.IP 3. 3
on the command line
.IP 4. 3
in a /*jslint*/ comment

.RE
.P
A higher number indicates a higher precedence, i\.e\. command line options
override options specified by an options file, and /*jslint*/ comments
in the file being examined have the highest precedence\.
.P
##EDITIONS
.P
You can now specify the edition of jslint with the \fI\-\-edition\fR option\.
.P
Future versions of this package may include newer editions of jslint;
to always use the latest edition of jslint, specify \-\-edition=latest:
.P
.RS 2
.nf
jslint \-\-edition=latest lib/*\.js
.fi
.RE
.P
The default edition of jslint will remain stable as long as the leading
two components of the version number are the same\.  New minor editions
may have a different default edition\.
.P
The previous version of this package (0\.1\.9) shipped an older edition
(2013\-02\-03) of jslint\.  To revert to that behavior but still have the
new config file features, upgrade to 0\.2\.1 of this package and specify
\fBedition: '2012\-02\-03'\fP in your jslintrc file or \fB\-\-edition=2013\-02\-03\fP
on the command line\.
.P
We recommend the following practices:
.P
###If your project is in maintenance mode
.P
Choose an edition of jslint and hardcode it into your project's lint config files, e\.g\.,
\fBedition: '2012\-02\-03'\fP\|\. Specify a fixed version of jslint (e\.g\., "0\.2\.1") as a
devDependency in package\.json
.P
###If your project needs temporary stability (e\.g\., release phase)
.P
Use the default edition of jslint (no \fB\-\-edition\fP argument needed) and specify
a fixed minor version  (e\.g, "~0\.2") as a devDependency in package\.json
.P
###If you want the bleeding\-edge version
.P
Specify \fBedition: 'latest'\fP and use any 'latest version' behavior in package\.json,
e\.g\., "*" or ">0\.2\.1"
.P
##RETURN VALUES
.P
jslint returns 1 if it found any problems, 0 otherwise\.
