argv-split

Split argv(argument vector) and handle special cases, such as quoted or escaped values.

Why?

const split = require('split')

const mkdir = 'mkdir "foo bar"'
mkdir.split(' ')    // ['mkdir', '"foo', 'bar"']  -> Oops!
split(mkdir)        // ['mkdir', 'foo bar']       -> Oh yeah!

const mkdir2 = 'mkdir foo\\ bar'.split(' ')
mkdir2.split(' ')   // ['mkdir', 'foo\\', 'bar']  -> Oops!
split(mkdir2)       // ['mkdir', 'foo bar']       -> Oh yeah!

argv-split handles all special cases with complete unit tests.

# shell command:        javascript array:
foo a\ b                # ['foo', 'a b']
foo \'                  # ['foo', '\\\'']
foo \"                  # ['foo', '\\"']
foo "a b"               # ['foo', 'a b']
foo "a\ b"              # ['foo', 'a\\ b']
foo '\'                 # ['foo', '\\']
foo --abc="a b"         # ['foo', '--abc=a b']
foo --abc=a\ b          # ['foo', '--abc=a b']

# argv-split also handles carriage returns
foo \
    --abc=a\ b          # ['foo', '--abc=a b']

# etc

split('foo \\\n    --abc=a\\ b')    // ['foo', '--abc=a b']

Error Codes

UNMATCHED_SINGLE

If a command missed the closing single quote, the error will throw:

Shell command:

foo --abc 'abc

try {
  split('foo --abc \'abc')
} catch (e) {
  console.log(e.code)   // 'UNMATCHED_SINGLE'
}

UNMATCHED_DOUBLE

If a command missed the closing double quote, the error will throw:

foo --abc "abc

ESCAPED_EOF

If a command unexpectedly ends with a \, the error will throw:

foo --abc a\# if there is nothing after \, the error will throw
foo --abc a\ # if there is a whitespace after, then -> ['foo', '--abc', 'a ']

NON_STRING

If the argument passed to split is not a string, the error will throw

split(undefined)

Install

$ npm install argv-split --save

split(string)
