" times. As an autoload function it can be called directly from within
" :so utl_3_0a.vba without starting a new Vim instance.
"
" - Deletes any existing obsolete files: plugin/utl_arr.vim, doc/utl_ref.txt
" - Data migration: Checks for utl_2.0 configuration variables and print
" instructions to user how to migrate them.
"
" Note: Utl 3.0a installation saved file plugin/utl_rc.vim to
" plugin/utl_old_rc.vim prior to Utl 3.0a installation (Preinstall). So the
" old variables remain and will be visible in new Vim instance.

" are separated with backslashes (most Windows programs need this).
" Note that full path might also contain a drive letter.
"
" %f - Replaced by fragment if given in URL, else replaced by empty string.
"
" Details :
" - The variable name is g:utl_cfg_hdl_mt_<media type>, where the characters / . + -
" which can appear in media types are mapped to _ to make a valid variable
" name, e.g. Vim variable for media type 'video/x-msvideo' is
" 'g:utl_cfg_hdl_mt_video_x_msvideo'
" - The "" around the %P is needed to support file names containing blanks
" - Remove the :silent when you are testing with a new string to see what's
" going on (see <URL:vimhelp::silent> for infos on the :silent command).
" Perhaps you like :silent also for production (I don't).
" - NOTE: You can supply any command here, i.e. does not need to be a shell
" command that calls an external program (some cmdline special treatment
" though, see <URL:utl.vim#r=esccmd>)
" - You can introduce new media types to not handle a certain media type
" by Vim (e.g. display it as text in Vim window). Just make sure that the
" new media type is also supported at this place:
" <URL:utl.vim#r=utl_checkmtype>

" by Vim. This yields the same result as if the media type is not defined,

" Version: utl 3.0a
" ------------------------------------------------------------------------------
" In this file some scheme specific retrieval functions are defined.
" For each scheme one function named Utl_AddrScheme_xxx() is needed.
"
" - If a scheme (i.e. functions) is missing, the caller Utl_processUrl()
" will notice it and show an appropriate message to the user.
"
" - You can define your own functions:
" How to write a Utl_AddrScheme_xxx function (id=implscmfunc)
" ------------------------------------------
" To implement a specific scheme (e.g. `file', `http') you have to write
" write a handler function named `Utl_AddrScheme_<scheme>' which obeys the
" following rules:
"
" - It takes three arguments:
"
" 1. Arg: Absolute URI
" (See <URL:vimhelp:utl-uri-relabs> to get an absolute URI explained). The
" given `auri' will not have a fragment (without #... at the end).
"
" 2. Arg: Fragment
" Where the value will be '<undef>' if there is no fragment. In most cases a
" handler will not actually deal with the fragment but leaves that job for
" standard fragment processing in Utl by returning a non empty list (see
" next). Examples for fragment processing handlers are
" Utl_AddressScheme_http and Utl_AddressScheme_foot.
"
" 3. Arg: display Mode (dispMode)
" Most handlers will ignore this argument. Exception for instance handlers
" which actually display the retrieved or determined file like
" Utl_AddressScheme_foot. If your function is smart it might, if applicable,
" support the special dispMode values copyFileName (see examples in this file).
"
"
" - It then does what ever it wants.
" But what it normally wants is: retrieve, load, query, address the resource
" identified by `auri'.
" - It Returns a list with 0 (empty list), 1 or 2 elements. [id=scm_ret_list]
" (See vimhelp:List if you don't know what a list is in Vim)
"
" * Empty list means: no subsequent processing by Utl.vim
" Examples where this makes sense:
" ° If the retrieve was not successful, or
" ° if handler already cared for displaying the file (e.g. URL
" delegated to external handler)
"
" * 1st list element = file name (called localPath) provided means:
" a) Utl.vim will delegate localPath to the appropriate file type handler
" or display it the file in Vim-Window.
" It also possible, that the localPath is already displayed in this case
" (Utl.vim will check if the localPath corresponds to a buffer name.)
" Note : It is even possible that localPath does not correspond to
" an existing file or to a file at all. Executing a http URL with
" netrw is an example for this, see: ../plugin/utl_rc.vim#http_netrw.
" Netrw uses the URL as buffer name.
" c) Fragment will be processed (if any).
"
" Details :
" ° File name should be a pathname to (an existing) local file or directory.
" Note : the
" ° File name's path separator should be slash (not backslash).
" ° It does not hurt if file is already displayed (an example for this is
" vimhelp scheme).
"
" * 2nd list element = fragment Mode (fragMode). Allowed values:
" `abs', 'rel'. Defaults to `abs' if no 2nd list element.
" `abs': Fragment will be addressed to beginning of file.
" `rel': Fragment will be addressed relative to current cursor position
" (example: Vimhelp scheme).
"
" Specification of 'scheme handler variable interface' (id=spec_ihsv)
" ----------------------------------------------------
"
" - Variable naming: utl_cfg_hdl_scm_<scheme>
"
" - Variables executed by :exe (see <vimhelp::exe>).
" This implies that the variable has to a valid ex command. (to execute more
" than one line of ex commands a function can be called).
"
" - Should handle the actual link, e.g. download the file.
" But it can do whatever it wants :-)
"
" - Input data: scheme specific conversion specifiers should appear in the
" variable. They will be replaced by Utl.vim when executing an URL, e.g %u
" will be replaced by the actual URL. The available conversion specifiers are
" defined at <url:../plugin/utl_rc.vim#r=utl_cfg_hdl_scm_http> for http etc.
"
" - Output data: an optional global list, which is the same as that of the
" handler itself, see <url:../plugin/utl_scm.vim#r=scm_ret_list>. Since the
" variable's value can be any ex command (and, for instance, not always a
" function) a global variable is used:
" g:utl_hdl_scm_ret_list
" This variable will be initialized to an empty list [] by Utl.vim before
" executing the contents of the variable.
"
" - Exception handling: Normally nothing needs to be done in the variable code.
" Utl.vim checks for v:shell_error and v:errmsg after execution. There are
" situation where setting v:errmsg makes sense. The variable might want to
" issue the error message (Utl.vim does not).

" File: plugin/utl_uri.vim -- module for parsing URIs
" Part of the Utl plugin, see ./utl.vim
" Author: Stefan Bittner <stb@bf-consulting.de>
" Licence: This program is free software; you can redistribute it and/or
" modify it under the terms of the GNU General Public License.
" See http://www.gnu.org/copyleft/gpl.txt
" Version: utl 3.0a
" ------------------------------------------------------------------------------
" Parses URI-References.
" (Can be used independantly from Utl.)
" (An URI-Reference is an URI + fragment: myUri#myFragment.
" See also <URL:vimhelp:utl-uri-refs>.
" Aims to be compliant with <URL:http://www.ietf.org/rfc/rfc2396.txt>
"
" NOTE: The distinction between URI and URI-Reference won't be hold out
" (is that correct english? %-\ ). It should be clear from the context.
" The fragment goes sometimes with the URI, sometimes not.
"
" Usage:
"
" " Parse an URI
" let uri = 'http://www.google.com/search?q=vim#tn=ubiquitous'
"
" let scheme = UtlUri_scheme(uri)
" let authority = UtlUri_authority(uri)
" let path = UtlUri_path(uri)
" let query = UtlUri_query(uri)
" let fragment = UtlUri_fragment(uri)
"
" " Rebuild the URI
" let uriRebuilt = UtlUri_build(scheme, authority, path, query, fragment)
"
" " UtlUri_build a new URI
" let uriNew = UtlUri_build('file', 'localhost', 'path/to/file', '<undef>', 'myFrag')
"
" " Recombine an uri-without-fragment with fragment to an uri
" let uriRebuilt = UtlUri_build_2(absUriRef, fragment)
"
" let unesc = UtlUri_unescape('a%20b%3f') " -> unesc==`a b?'
"
" Details:
" Authority, query and fragment can have the <undef> value (literally!)
" (similar to undef-value in Perl). That's distinguished from
" _empty_ values! Example: http:/// yields UtlUri_authority=='' where as
" http:/path/to/file yields UtlUri_authority=='<undef>'.
" See also
" <URL:http://www.ietf.org/rfc/rfc2396.txt#Note that we must be careful>
"
" Internal Note:
" Ist not very performant in typical usage (but clear).
" s:UtlUri_parse executed n times for getting n components of same uri
