Package:: stx:libhtml

Category:: Net-Communication-Support

Description:

(for now) only a holder for the parse URL info.
Will takeover more functionality in the near future.

Please Notice: 
    this class is more or less obsoleted by URI, which provides better support
    for multiple transports, passwords etc. 
    However, a lot of old code still uses URL, and also Squeak has an URL as well. 
    So this remains here, although this has a slight duplicate-code odeur.
    Please use URI if possible.

this only cares for the scheme-transparent parts:
scheme, host, port, path
It does not split the path into local-anchor / search-args / post-args.
TODO: after parsing the scheme, let scheme-specific class parse the rest
(to allow for MailToUrl, LdapUrl, etc.)

Usage example(s):

     self oldFromURLString:'checkout.stt'.   
     self fromURLString:'checkout.stt'.

isValidMethod: aMethod: mhmh - is this a good idea (isn't it the task of a url-user to decide, which
methods it supports).
The URL does not really know...
newsGroup: If the receiver is an nntp url, return the news group; otherwise, return nil.
postData
postData: aString
requestString: everything but the host & scheme (i.e. path+options alone, as in an HTTP requests header line)
searchPart
searchPart: aString

testing

isHttpsUrl
isURL: (comment from inherited method)
Return true if the receiver is a url.
Note: Do not override in any class except URL.

utilities

/ aString

filename compatibility protocol:
A a new instance with aString concatenated to my path.
We simply append aString to the end of the path.
Look at construct for a more enhanced implementation.

Usage example(s):

      'http://www.exept.de/start' asURL / 'bla'
      'http://www.exept.de/start/' asURL / 'bla'
      'http://www.exept.de' asURL / 'bla'

construct: anUrlOrString

filename compatibility protocol:
return a URL with a path which is the concatenation
of my path and anUrlOrString.
If anUrlOrString is a URL and has another method or host than the receiver,
it is returned plain.
Also, if anUrlOrString is either an URL representing an absolute path.
I.e. this method can be used to compute an html document's anchor's target URL

Usage example(s):

       (URL fromString: 'http://www/dir/file.html') construct: (URL fromString: 'subdir/image.gif').
       (URL fromString: 'http://www/dir1/file.html') construct: (URL fromString: '/dir2/image.gif').
       (URL fromString: 'http://www/dir1/file.html') construct: (URL fromString: '~kyasu/').
       (URL fromString: 'http://www/dir/file.html') construct: (URL fromString: '#introduction').
       (URL fromString: 'http://www/dir/file.html') construct: (URL fromString: '/cgi-bin/perl.pl&dest=/other').
       (URL fromString: 'http://www/dir/file.html') construct: (URL fromString: 'http:/cgi-bin/perl.pl&dest=/other').
       (URL fromString: 'http://www-s2.rsl.crl.fujixerox.co.jp/~kyasu/') construct: (URL fromString: 'http://arrow').
       (URL fromString: 'gopher://www.com') construct: (URL fromString: '//www.com:70/ParcBenchMain').
       (URL fromString: 'http://www/some.html') construct: (URL fromString: 'http://www/').
       (URL fromString: '../tmp/table.html') construct: (URL fromString: 'kyasu.gif').

constructString: anUrlOrString

filename compatibility protocol

Usage example(s):

       (URL fromString: 'http://www/dir/') constructString:'subdir/image.gif'.

directory

filename compatibility protocol:
return a URL which represents the receiver's directoy

Usage example(s):

     'http://www.exept.de:8080/foo/bar/baz.txt' asURL directory
     'file:///foo/bar/baz.txt' asURL directory

pathBasename

answer the baseName of my path as a string.
eg. for '/part1/part2/part3.suffix' this is 'part3.suffix'

Usage example(s):

     'http://www.exept.de:8080/foo/bar/baz.txt' asURL pathBasename
     'file:///foo/bar/baz.txt' asURL pathBasename

pathSuffix

answer the suffix of my path as a string.
eg. for '/part1/part2/part3.suffix' this is 'suffix'

Usage example(s):

     'http://www.exept.de:8080/foo/bar/baz.txt' asURL pathSuffix
     'file:///foo/bar/baz.txt' asURL pathSuffix

pathWithoutSuffix

answer the baseName of my path as a string.
eg. for 'http://host/part1/part2/part3.suffix' this is '/part1/part2/part3'

Usage example(s):

     'http://www.exept.de:8080/foo/bar/baz.txt' asURL pathWithoutSuffix
     'file:///foo/bar/baz.txt' asURL pathWithoutSuffix
