shell-quote
Parse and quote shell commands.
example
quote
var quote = require('shell-quote/quote');
var s = quote([ 'a', 'b c d', '$f', '"g"' ]);
console.log(s);
output
a 'b c d' \$f '"g"'
parse
var parse = require('shell-quote/parse');
var xs = parse('a "b c" \\$def \'it\\\'s great\'');
console.dir(xs);
output
[ 'a', 'b c', '\\$def', 'it\'s great' ]
parse with an environment variable
var parse = require('shell-quote/parse');
var xs = parse('beep --boop="$PWD"', { PWD: '/home/robot' });
console.dir(xs);
output
[ 'beep', '--boop=/home/robot' ]
parse with custom escape character
var parse = require('shell-quote/parse');
var xs = parse('beep ^--boop="$PWD"', { PWD: '/home/robot' }, { escape: '^' });
console.dir(xs);
output
[ 'beep --boop=/home/robot' ]
parsing shell operators
var parse = require('shell-quote/parse');
var xs = parse('beep || boop > /byte');
console.dir(xs);
output:
[ 'beep', { op: '||' }, 'boop', { op: '>' }, '/byte' ]
parsing shell comment
var parse = require('shell-quote/parse');
var xs = parse('beep > boop # > kaboom');
console.dir(xs);
output:
[ 'beep', { op: '>' }, 'boop', { comment: '> kaboom' } ]
methods
var quote = require('shell-quote/quote');
var parse = require('shell-quote/parse');
quote(args)
Return a quoted string for the array args
suitable for using in shell
commands.
parse(cmd, env={})
Return an array of arguments from the quoted string cmd
.
Interpolate embedded bash-style $VARNAME
and ${VARNAME}
variables with
the env
object which like bash will replace undefined variables with ""
.
env
is usually an object but it can also be a function to perform lookups.
When env(key)
returns a string, its result will be output just like env[key]
would. When env(key)
returns an object, it will be inserted into the result
array like the operator objects.
When a bash operator is encountered, the element in the array with be an object
with an "op"
key set to the operator string. For example:
'beep || boop > /byte'
parses as:
[ 'beep', { op: '||' }, 'boop', { op: '>' }, '/byte' ]
