Str? auth()

The authority represents a network endpoint in the format:

[<userInfo> "@"] host [":" <port>]

Examples:

`http://user@host:99/`.auth  =>  "user@host:99"
`http://host/`.auth          =>  "host"
`/dir/file.txt`.auth         =>  null

Str basename()

Return file name without the extension (everything up to the last dot) or "" if name is "".

Examples:

`/`.basename            =>  ""
`/a/file.txt`.basename  =>  "file"
`/a/file`.basename      =>  "file"
`/a/file.`.basename     =>  "file"
`..`.basename           =>  ".."

static Void checkName(Str name)

If the specified string is not a valid name according to the isName method, then throw NameErr.

static Uri? decode(Str s, Bool checked := true)

Parse an ASCII percent encoded string into a Uri according to RFC 3986. All %HH escape sequences are translated into octects, and then the octect sequence is UTF-8 decoded into a Str. The + character in the query section is unescaped into a space. If checked if true then throw ParseErr if the string is a malformed URI or if not encoded correctly, otherwise return null. Refer to fromStr for normalization rules.

static Str:Str decodeQuery(Str s)

Decode a map of query parameters which are URL encoded according to the "application/x-www-form-urlencoded" MIME type. This method will unescape % percent encoding and + into space. The parameters are parsed into map using the same semantics as Uri.query. Throw ArgErr is the string is malformed. See encodeQuery.

static Str decodeToken(Str s, Int section)

Unescape "%xx" percent encoded string to its normalized form for the given section. Any delimiters for the section are backslash escaped. Section must be sectionPath, sectionQuery, or sectionFrag. Also see encodeToken.

Examples:

Uri.decodeToken("a%2Fb%23c", Uri.sectionPath)  =>  "a\/b\#c"
Uri.decodeToken("a%3Db/c", Uri.sectionQuery)   =>  "a\=b/c"

const static Uri defVal

Default value is ``.

Str encode()

Return the percent encoded string for this Uri according to RFC 3986. Each section of the Uri is UTF-8 encoded into octects and then percent encoded according to its valid character set. Spaces in the query section are encoded as +.

static Str encodeQuery(Str:Str q)

Encode a map of query parameters into URL percent encoding according to the "application/x-www-form-urlencoded" MIME type. See decodeQuery.

static Str encodeToken(Str s, Int section)

Encode a token so that any invalid character or delimter for the given section is "%xx" percent encoding. Section must be sectionPath, sectionQuery, or sectionFrag. Also see decodeToken.

Examples:

Uri.encodeToken("a/b#c", Uri.sectionPath)   =>  "a%2Fb%23c"
Uri.encodeToken("a=b/c", Uri.sectionQuery)  =>  "a%3Db/c"

virtual override Bool equals(Obj? that)

Two Uris are equal if they have same string normalized representation.

static Str escapeToken(Str s, Int section)

Escape a token so that any delimter for the given section is backslash escaped for use in normalized URI form. Section must be sectionPath, sectionQuery, or sectionFrag.

Examples:

Uri.escapeToken("a/b#c", Uri.sectionPath)   =>  "a\/b\#c"
Uri.escapeToken("a=b/c", Uri.sectionQuery)  =>  "a\=b/c"

Str? ext()

Return file name extension (everything after the last dot) or null if name is null or name has no dot.

Examples:

`/`.ext            =>  null
`/a/file.txt`.ext  =>  "txt"
`/Foo.Bar`.ext     =>  "Bar"
`/a/file`.ext      =>  null
`/a/file.`.ext     =>  ""
`..`.ext           =>  null

Str? frag()

Return the fragment component of the Uri which is everything after the "#". Return null if no fragment specified.

Examples:

`http://host/path?query#frag`.frag  =>  "frag"
`http://host/path`                  =>  null
`#h1`                               =>  "h1"

static new fromStr(Str s, Bool checked := true)

Parse the specified string into a Uri. If invalid format and checked is false return null, otherwise throw ParseErr. a standard form Unicode string into its generic parts. It does not unescape % or + and handles normal Unicode characters in the string. If general delimiters such as the "?" or "#" characters are used outside their normal role, then they must be backslash escaped.

All Uris are automatically normalized as follows:

• Replacing "." and ".." segments in the middle of a path
• Scheme always normalizes to lowercase
• If http then port 80 normalizes to null
• If http then a null path normalizes to /

Obj? get(Obj? base := null, Bool checked := true)

Resolve this Uri into an Fantom object. See docLang for the resolve process.

@Operator
Uri getRange(Range r)

Return a new Uri based on a slice of this Uri's path. If the range starts at zero, then the authority is included otherwise it is stripped and the result is not path absolute. If the range includes the last name in the path, then the query and fragment are included otherwise they are stripped and the result includes a trailing slash. The range can include negative indices to access from the end of the path. Also see pathOnly to create a slice without the authority, query, or fragment.

Examples:

`http://host/a/b/c?q`[0..-1]  =>  `http://host/a/b/c?q`
`http://host/a/b/c?q`[0..-2]  =>  `http://host/a/b/`
`http://host/a/b/c?q`[0..-3]  =>  `http://host/a/`
`http://host/a/b/c?q`[0..-4]  =>  `http://host/`
`http://host/a/b/c?q`[1..-1]  =>  `b/c?q`
`http://host/a/b/c?q`[2..-1]  =>  `c?q`
`http://host/a/b/c?q`[3..-1]  =>  `?q`
`/a/b/c/`[0..1]               =>  `/a/b/`
`/a/b/c/`[0..0]               =>  `/a/`
`/a/b/c/`[1..2]               =>  `b/c/`
`/a/b/c/`[1..<2]              =>  `b/`
`/a`[0..-2]                   =>  `/`

Uri getRangeToPathAbs(Range r)

Return a slice of this Uri's path using the same semantics as getRange. However this method ensures that the result has a leading slash in the path such that isPathAbs returns true.

Examples:

`/a/b/c/`.getRangeToPathAbs(0..1)  =>  `/a/b/`
`/a/b/c/`.getRangeToPathAbs(1..2)  =>  `/b/c/`
`/a/b/c/`.getRangeToPathAbs(1..<2) =>  `/b/`

virtual override Int hash()

Return a hash code based on the normalized string representation.

Str? host()

Return the host address of the URI or null if not available. The host is in the format of a DNS name, IPv4 address, or IPv6 address surrounded by square brackets. Return null if the uri is not absolute.

Examples:

`ftp://there:78/file`.host            =>  "there"
`http://www.cool.com/`.host           =>  "www.cool.com"
`http://[email protected]/index`.host =>  "10.162.255.4"
`http://[::192.9.5.5]/`.host          =>  "[::192.9.5.5]"
`//foo/bar`.host                      =>  "foo"
`/bar`.host                           =>  null

Bool isAbs()

Return if an absolute Uri which means it has a non-null scheme.

Bool isDir()

A Uri represents a directory if it has a non-null path which ends with a "/" slash. Directories are joined with other Uris relative to themselves versus non-directories which are joined relative to their parent.

Examples:

`/a/b`.isDir   =>  false
`/a/b/`.isDir  =>  true
`/a/?q`.isDir  =>  true

static Bool isName(Str name)

Return if the specified string is an valid name segment to use in an unencoded URI. The name must be at least one char long and can never be "." or "..". The legal characters are defined by as follows from RFC 3986:

unreserved  =  ALPHA / DIGIT / "-" / "." / "_" / "~"
ALPHA       =  %x41-5A / %x61-7A   ; A-Z / a-z
DIGIT       =  %x30-39 ; 0-9

Although RFC 3986 does allow path segments to contain other special characters such as sub-delims, Fantom takes a strict approach to names to be used in URIs.

Bool isPathAbs()

Return if the path starts with a leading slash. If pathStr is empty, then return false.

Examples:

`http://foo/`.isPathAbs    =>  true
`/dir/f.txt`.isPathAbs     =>  true
`dir/f.txt`.isPathAbs      =>  false
`../index.html`.isPathAbs  =>  false

Bool isPathOnly()

Return if this Uri contains only a path component. The authority (scheme, host, port), query, and fragment must be null.

Bool isPathRel()

Return not of isPathAbs when path is empty or does not start with a leading slash.

Bool isRel()

Return if a relative Uri which means it has a null scheme.

MimeType? mimeType()

Return the MimeType mapped by the ext or null if no mapping. If this uri is to a directory, then "x-directory/normal" is returned.

Examples:

`file.txt`  =>  text/plain
`somefile`  =>  null

Str name()

Return simple file name which is path.last or "" if the path is empty.

Examples:

`/`.name            =>  ""
`/a/file.txt`.name  =>  "file.txt"
`/a/file`.name      =>  "file"
`somedir/`.name     =>  "somedir"

Uri? parent()

Return the parent directory of this Uri or null if a parent path cannot be computed from this Uri. If the path is not empty, then this method is equivalent to getRange(0..-2).

Examples:

`http://foo/a/b/c?q#f`.parent  =>  `http://foo/a/b/`
`/a/b/c/`.parent  =>  `/a/b/`)
`a/b/c`.parent    =>  `a/b/`
`/a`.parent       =>   `/`
`/`.parent        =>   null
`a.txt`.parent    =>   null

Str[] path()

Return the path parsed into a list of simple names or an empty list if the pathStr is "" or "/". Any general delimiters in the path such "?" or "#" are backslash escaped.

Examples:

`mailto:[email protected]`  =>  ["[email protected]"]
`http://host`.path     =>  Str[,]
`http://foo/`.path     =>  Str[,]
`/`.path               =>  Str[,]
`/a`.path              =>  ["a"]
`/a/b`.path            =>  ["a", "b"]
`../a/b`.path          =>  ["..", "a", "b"]

Uri pathOnly()

Return a new Uri with only a path part. If this Uri has an authority, fragment, or query they are stripped off.

Examples:

`http://host/a/b/c?query`.pathOnly =>  `/a/b/c`
`http://host/a/b/c/`.pathOnly      =>  `/a/b/c/`
`/a/b/c`.pathOnly                  =>  `/a/b/c`
`file.txt`.pathOnly                =>  `file.txt`

Str pathStr()

Return the path component of the Uri. Any general delimiters in the path such "?" or "#" are backslash escaped.

Examples:

`mailto:[email protected]`  =>  "[email protected]"
`http://host`          =>  ""
`http://foo/`.pathStr  =>  "/"
`/a`.pathStr           =>  "/a"
`/a/b`.pathStr         =>  "/a/b"
`../a/b`.pathStr       =>  "../a/b"

@Operator
Uri plus(Uri toAppend)

Return a new Uri with the specified Uri appended to this Uri.

Examples:

`http://foo/path` + `http://bar/`  =>  `http://bar/`
`http://foo/path?q#f` + `newpath`  =>  `http://foo/newpath`
`http://foo/path/?q#f` + `newpath` =>  `http://foo/path/newpath`
`a/b/c`  + `d`                     =>  `a/b/d`
`a/b/c/` + `d`                     =>  `a/b/c/d`
`a/b/c`  + `../../d`               =>  `d`
`a/b/c/` + `../../d`               =>  `a/d`
`a/b/c`  + `../../../d`            =>  `../d`
`a/b/c/` + `../../../d`            =>  `d`

Uri plusName(Str name, Bool asDir := false)

Return a new Uri with a single path name appended to this Uri. If asDir is true, then add a trailing slash to the Uri to make it a directory Uri. This method is potentially much more efficient than using plus when appending a single name.

Examples:

`dir/`.plusName("foo")        =>  `dir/foo`
`dir/`.plusName("foo", true)  =>  `dir/foo/`
`/dir/file`.plusName("foo")   =>  `/dir/foo`
`/dir/#frag`.plusName("foo")  =>  `/dir/foo`

Uri plusQuery([Str:Str]? query)

Add the specified query key/value pairs to this Uri. If this uri has an existing query, then it is merged with the given query. The key/value pairs should not be backslash escaped or percent encoded. If the query param is null or empty, return this instance.

Examples:

`http://h/`.plusQuery(["k":"v"])         =>  `http://h/?k=v`
`http://h/?k=old`.plusQuery(["k":"v"])   =>  `http://h/?k=v`
`/foo?a=b`.plusQuery(["k":"v"])          =>  `/foo?a=b&k=v`
`?a=b`.plusQuery(["k1":"v1", "k2":"v2"]) =>  `?a=b&k1=v1&k2=v2`

Uri plusSlash()

Add a trailing slash to the path string of this Uri to make it a directory Uri.

Examples

`http://h/dir`.plusSlash  => `http://h/dir/`
`/a`.plusSlash            =>  `/a/`
`/a/`.plusSlash           =>  `/a/`
`/a/b`.plusSlash          =>  `/a/b/`
`/a?q`.plusSlash          =>  `/a/?q`

Int? port()

Return the IP port of the host for the network end point. It is optionally embedded in the authority using the ":" character. If unspecified then return null.

Examples:

`http://foo:81/`.port        =>  81
`http://www.cool.com/`.port  =>  null

Str:Str query()

Return the query parsed as a map of key/value pairs. If no query string was specified return an empty map (this method will never return null). The query is parsed such that pairs are separated by the "&" or ";" characters. If a pair contains the "=", then it is split into a key and value, otherwise the value defaults to "true". If delimiters such as "&", "=", or ";" are in the keys or values, then they are not escaped. If duplicate keys are detected, then the values are concatenated together with a comma.

Examples:

`http://host/path?query`.query  =>  ["query":"true"]
`http://host/path`.query        =>  [:]
`?a=b;c=d`.query                =>  ["a":"b", "c":"d"]
`?a=b&c=d`.query                =>  ["a":"b", "c":"d"]
`?a=b;;c=d;`.query              =>  ["a":"b", "c":"d"]
`?a=b;;c`.query                 =>  ["a":"b", "c":"true"]
`?x=1&x=2&x=3`.query            =>  ["x":"1,2,3"]

Str? queryStr()

Return the query component of the Uri which is everything after the "?" but before the "#" fragment. Return null if no query string specified. Any delimiters used in keys or values such as "&", "=", or ";" are backslash escaped.

Examples:

`http://host/path?query#frag`.queryStr =>  "query"
`http://host/path?query`.queryStr      =>  "query"
`http://host/path`.queryStr            =>  null
`../foo?a=b&c=d`.queryStr              =>  "a=b&c=d"
`?a=b;c;`.queryStr                     =>  "a=b;c;"

Uri relTo(Uri base)

Relativize this uri against the specified base.

Examples:

`http://foo/a/b/c`.relTo(`http://foo/a/b/c`) => ``
`http://foo/a/b/c`.relTo(`http://foo/a/b`)   => `c`
`/a/b/c`.relTo(`/a`)                         => `b/c`
`a/b/c`.relTo(`/a`)                          => `b/c`
`/a/b/c?q`.relTo(`/`)                        => `a/b/c?q`
`/a/x`.relTo(`/a/b/c`)                       => `../x`

Uri relToAuth()

Relativize this uri against its authority. This method strips the authority if present and keeps the path, query, and fragment segments.

Examples:

`http://host/a/b/c?q#frag`.relToAuth  => `/a/b/c?q#frag`
`http://host/a/b/c`.relToAuth         => `/a/b/c`
`http://user@host/index`.relToAuth    => `/index`
`mailto:[email protected]`.relToAuth        => `[email protected]`
`/a/b/c/`.relToAuth                   => `/a/b/c/`
`logo.png`.relToAuth                  => `logo.png`

Str? scheme()

Return the scheme component or null if not absolute. The scheme is always normalized into lowercase.

Examples:

`http://foo/a/b/c`.scheme      =>  "http"
`HTTP://foo/a/b/c`.scheme      =>  "http"
`mailto:[email protected]`.scheme  =>  "mailto"

const static Int sectionFrag

Fragment token section flag

const static Int sectionPath

Path token section flag

const static Int sectionQuery

Query token section flag

Str toCode()

Get this Uri as a Fantom code literal. This method will escape the "$" interpolation character.

File toFile()

If scheme is non-null, then this is conveninece for get cast to a File. If scheme is null then is a convenience for File.make(this) which maps to a file on the local file system.

Str toLocale()

Return toStr. This method is used to enable toLocale to be used with duck typing across most built-in types.

virtual override Str toStr()

Return normalized string representation.

static Str unescapeToken(Str s)

Unescape all backslash escape sequences.

Examples:

Uri.unescapeToken(Str<|a\#b|>)  =>  "a#b"

Str? userInfo()

User info is string information embedded in the authority using the "@" character. Its use is discouraged for security reasons.

Examples:

`http://brian:pass@host/`.userInfo  =>  "brian:pass"
`http://www.cool.com/`.userInfo     =>  null
