Documentation

Encodes a list of path segments into a valid URL fragment.

This function takes the following three steps:

• UTF-8 encodes the characters.
• Performs percent encoding on all unreserved characters, as well as :@=+$,
• Intercalates with a slash.

For example:

encodePathInfo [\"foo\", \"bar\", \"baz\"]

"foo/bar/baz"

encodePathInfo [\"foo bar\", \"baz\/bin\"]

"foo%20bar/baz%2Fbin"

encodePathInfo [\"שלום\"]

"%D7%A9%D7%9C%D7%95%D7%9D"

Performs the inverse operation of encodePathInfo.

In particular, this function:

• Splits a string at each occurence of a forward slash.
• Percent-decodes the individual pieces.
• UTF-8 decodes the resulting data.

This utilizes decodeString from the utf8-string library, and thus all UTF-8 decoding errors are handled as per that library.

In general, you will want to strip the leading slash from a pathinfo before passing it to this function. For example:

decodePathInfo \"\"

[]

decodePathInfo \"\/\"

""

Note that while function accepts a Text value, it is expected that Text will only contain the subset of characters which are allowed to appear in a URL.

Returns path segments as well as possible query string components

For example:

decodePathInfoParams "/home?q=1"

(["home"],[("q",Just "1")])
