+# argv-split
+
+Split argv(argument vector) and handle special cases, such as quoted or escaped values.
+
+## Why?
+
+```js
+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.
+
+```sh
+# 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
+```
+
+```js
+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:
+
+```sh
+foo --abc 'abc
+```
+
+```js
+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:
+
+```sh
+foo --abc "abc
+```
+
+### `ESCAPED_EOF`
+
+If a command unexpectedly ends with a `\`, the error will throw:
+
+```sh
+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
+
+```js
+split(undefined)
+```
+
+## Install
+
+```sh
+$ npm install argv-split --save
+```
+
+### split(string)
+
+Splits a string, and balance quoted parts. The usage is quite simple, see examples above.
+
+Returns `Array`
+
+
+### ~~split.join()~~
+
+Temporarily removed in `2.0.0`, and will be added in `2.1.0`
