=head1 NAME

Code::TidyAll::Plugin::JSHint - Use jshint with tidyall

=head1 VERSION

version 0.69

=head1 SYNOPSIS

   In configuration:

   ; With default settings
   ;
   [JSHint]
   select = static/**/*.js

   ; Specify options inline
   ;
   [JSHint]
   select = static/**/*.js
   options = bitwise camelcase latedef

   ; or refer to a jshint.json config file in the same directory
   ;
   [JSHint]
   select = static/**/*.js
   argv = --config $ROOT/jshint.json

   where jshint.json looks like

   {
      "bitwise": true,
      "camelcase": true,
      "latedef": true
   }

=head1 DESCRIPTION

Runs L<jshint|http://www.jshint.com/>, a JavaScript validator, and dies if any
problems were found.

=head1 INSTALLATION

See installation options at L<jshint|http://www.jshint.com/platforms/>. One
easy method is to install L<npm|https://npmjs.org/>, then run

    npm install jshint -g

=head1 CONFIGURATION

This plugin accepts the following configuration options:

=head2 argv

Arguments to pass to C<jshint>.

=head2 cmd

The path for the C<jshint> command. By default this is just C<jshint>, meaning
that the user's C<PATH> will be searched for the command.

=head2 options

A whitespace separated string of options, as L<documented by
jshint|http://www.jshint.com/docs/>. These will be written to a temporary
config file and passed as C<--config> argument.

=head1 SUPPORT

Bugs may be submitted at
L<https://github.com/houseabsolute/perl-code-tidyall/issues>.

I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
