-This file contains the particularities for the RISC OS version of Vim.
+The RISC OS support has been removed from Vim with patch 7.3.187.
+If you would like to use Vim on RISC OS get the files from before that patch.
 
-The RISC OS port is a completely new port and is not based on the old "archi"
-port.

-==============================================================================
-							*riscos-locations*
-1. File locations
-
-The Vim executable and shared resource files are all stored inside the !Vim
-application directory.
-
-When !Vim is first seen by the filer, it aliases the *vi and *ex commands to
-run the command-line versions of Vim (see |riscos-commandline|).
-
-!Vim.Resources and !Vim.Resources2 contain the files from the standard Vim
-distribution, but modified slightly to work within the limits of ADFS, plus
-some extra files such as the window templates.
-
-User choices are read from "Choices:*" and are saved to "<Choices$Write>.*".
-If you have the new !Boot structure then these should be set up already.  If
-not, set Choices$Path to a list of directories to search when looking for
-user configuration files.  Set Choices$Write to the directory you want files
-to be saved into (so your search patterns and marks can be remembered between
-sessions).
-
-==============================================================================
-							*riscos-munging*
-2. Filename munging
-
-All pathname munging is disabled by default, so Vim should behave like a
-normal RISC OS application now.  So, if you want to edit "doc/html" then you
-actually type "*vi doc/html".
-
-The only times munging is done is when:
-
-- Searching included files from C programs, since these are always munged.
-  See |[I|.
-  Note: make sure you are in the right directory when you use this
-	command (i.e. the one with subdirectories "c" and "h").
-
-- Sourcing files using |:so|.
-  Paths starting "$VIM/" are munged like this:
-
-  $VIM/syntax/help.vim  ->  Vim:syntax.help
-
-  Also, files ending in ".vim" have their extensions removed, and slashes
-  replaced with dots.
-
-Some tag files and script files may have to be edited to work under this port.
-
-==============================================================================
-							*riscos-commandline*
-3. Command-line use
-
-To use Vim from the command-line use the "*vi" command (or "*ex" for
-|Ex-mode|).
-
-Type "*vi -h" for a list of options.
-
-Running the command-line version of Vim in a large high-color mode may cause
-the scrolling to be very slow.  Either change to a mode with fewer colors or
-use the GUI version.
-
-Also, holding down Ctrl will slow it down even more, and Ctrl-Shift will
-freeze it, as usual for text programs.
-
-==============================================================================
-							*riscos-gui*
-4. Desktop use
-
-Limitations:
-
-- Left scrollbars don't work properly (right and bottom are fine).
-- Doesn't increase scroll speed if it gets behind.
-
-You can resize the window by dragging the lower-right corner, even though
-there is no icon shown there.
-
-You can use the --rows and --columns arguments to specify the initial size of
-the Vim window, like this: >
-
-  *Vi -g --rows 20 --columns 80
-
-The global clipboard is supported, so you can select some text and then
-paste it directly into another application (provided it supports the
-clipboard too).
-
-Clicking Menu now opens a menu like a normal RISC OS program.  Hold down Shift
-when clicking Menu to paste (from the global clipboard).
-
-Dragging a file to the window replaces the CURRENT buffer (the one with the
-cursor, NOT the one you dragged to) with the file.
-
-Dragging with Ctrl held down causes a new Vim window to be opened for the
-file (see |:sp|).
-
-Dragging a file in with Shift held down in insert mode inserts the pathname of
-the file.
-
-:browse :w opens a standard RISC OS save box.
-:browse :e opens a directory viewer.
-
-For fonts, you have the choice of the system font, an outline font, the system
-font via ZapRedraw and any of the Zap fonts via ZapRedraw: >
-
-  :set guifont=
-<			To use the system font via the VDU drivers.  Supports
-			bold and underline.
->
-  :set guifont=Corpus.Medium
-<			Use the named outline font.  You can use any font, but
-			only monospaced ones like Corpus look right.
->
-  :set guifont=Corpus.Medium:w8:h12:b:i
-<			As before, but with size of 8 point by 12 point, and
-			in bold italic.
-			If only one of width and height is given then that
-			value is used for both.  If neither is given then 10
-			point is used.
-
-Thanks to John Kortink, Vim can use the ZapRedraw module.  Start the font name
-with "!" (or "!!" for double height), like this: >
-
-  :set guifont=!!
-<			Use the system font, but via ZapRedraw.  This gives a
-			faster redraw on StrongARM processors, but you can't
-			get bold or italic text.  Double height.
->
-  :set guifont=!script
-<			Uses the named Zap font (a directory in VimFont$Path).
-			The redraw is the same speed as for "!!", but you get
-			a nicer looking font.
-			Only the "man+" and "script" fonts are supplied
-			currently, but you can use any of the Zap fonts if
-			they are in VimFont$Path.
-			Vim will try to load font files "0", "B", "I" and "IB"
-			from the named directory.  Only "0" (normal style) MUST
-			be present.  Link files are not currently supported.
-
-Note that when using ZapRedraw the edit bar is drawn in front of the character
-you are on rather than behind it.  Also redraw is incorrect for screen modes
-with eigen values of 0.  If the font includes control characters then you can
-get Vim to display them by changing the 'isprint' option.
-
-If you find the scrolling is too slow on your machine, try experimenting
-with the 'scrolljump' and 'ttyscroll' options.
-
-In particular, StrongARM users may find that: >
-
-  :set ttyscroll=0
-
-makes scrolling faster in high-color modes.
-
-=============================================================================
-							*riscos-remote*
-5. Remote use (telnet)
-
-I have included a built-in termcap entry, but you can edit the termcap file to
-allow other codes to be used if you want to use Vim from a remote terminal.
-
-Although I do not have an internet connection to my Acorn, I have managed to
-run Vim in a FreeTerm window using the loopback connection.
-
-It seems to work pretty well now, using "*vi -T ansi".
-
-==============================================================================
-							*riscos-temp-files*
-6. Temporary files
-
-If Vim crashes then the swap and backup files (if any) will be in the
-directories set with the 'directory' and 'bdir' options.  By default the swap
-files are in <Wimp$ScrapDir> (i.e. inside !Scrap) and backups are in the
-directory you were saving to.  Vim will allow you to try and recover the file
-when you next try to edit it.
-
-To see a list of swap files, press <F12> and type "*vi -r".
-
-Vim no longer brings up ATTENTION warnings if you try to edit two files with
-the same name in different directories.
-
-However, it also no longer warns if you try to edit the same file twice (with
-two copies of Vim), though you will still be warned when you save that the
-datestamp has changed.
-
-==============================================================================
-							*riscos-interrupt*
-7. Interrupting
-
-To break out of a looping macro, or similar, hold down Escape in the
-command-line version, or press CTRL-C in the GUI version.
-
-==============================================================================
-							*riscos-memory*
-8. Memory usage
-
-Vim will use dynamic areas on RISC OS 3.5 or later.  If you can use them on
-older machines then edit the !RunTxt and GVim files.  I don't know what UnixLib
-does by default on these machines so I'm playing safe.
-
-It doesn't work at all well without dynamic areas, since it can't change its
-memory allocation once running.  Hence you should edit "!Vim.GVim" and
-"!Vim.!RunTxt" to choose the best size for you.  You probably need at least
-about 1400K.
-
-==============================================================================
-							*riscos-filetypes*
-9. Filetypes
-
-You can now specify that autocommands are only executed for files of certain
-types.  The filetype is given in the form &xxx, when xxx is the filetype.
-
-Filetypes must be specified by number (e.g. &fff for Text).
-
-The system has changed from version 5.3.  The new sequence of events is:
-
-- A file is loaded. |'osfiletype'| is set to the RISC OS filetype.
-- Based on the filetype and pathname, Vim will try to set |'filetype'| to the
-  Vim-type of the file.
-- Setting this option may load syntax files and perform other actions.
-- Saving the file will give it a filetype of |'osfiletype'|.
-
-Some examples may make this clearer:
-
-  Kind of file loaded	osfiletype	filetype ~
-  C code "c.hellow"	Text (&fff)	C
-  LaTeX document	LaTeX (&2a8)	TeX
-  Draw document		DrawFile (&aff)	(not changed)
-
-==============================================================================
-							*riscos-shell*
-10. The shell
-
-- Bangs (!s) are only replaced if they are followed by a space or end-of-line,
-  since many pathnames contain them.
-
-- You can prefix the command with "~", which stops any output from being
-  displayed.  This also means that you don't have to press <Enter> afterwards,
-  and stops the screen from being redrawn. {only in the GUI version}
-
-==============================================================================
-							*riscos-porting*
-11. Porting new releases to RISC OS
-
-Downloading everything you need:
-
-- Get the latest source distribution (see www.vim.org)
-- Get the runtime environment files (e.g. these help files)
-- Get the RISC OS binary distribution (if possible)
-
-
-Unarchiving:
-
-- Create a raFS disk and put the archives on it
-- Un-gzip them
-- Un-tar them   (*tar xELf 50 archive/tar)
-
-
-Recompiling the sources:
-
-- Create c, s, and h directories.
-- Put all the header files in "h".	     \
-- Put all the C files in "c".		     | And lose the extensions
-- Put the assembler file ("swis/s") in "s".  /
-- Rename all the files in "proto" to "h", like this:
-    raFS::VimSrc.source.proto.file/pro
-	  becomes
-    raFS::VimSrc.source.h.file_pro
-- In the files "h.proto" and "c.termlib", search and replace
-    .pro"
-       with
-    _pro.h"
-- Create a simple Makefile if desired and do "*make -k".
-  Use "CC = gcc -DRISCOS -DUSE_GUI -O2 -x c" in the Makefile.
-- Save the binary as !Vim.Vim in the binary distribution.
-
-
-Updating the run-time environment:
-
-- Replace old or missing files inside !Vim.Resources with the
-  new files.
-- Remove files in "doc" not ending in "/txt", except for "tags".
-- Lose the extensions from the files in "doc".
-- Edit the "doc.tags" file.  Remove extensions from the second column: >
-	:%s/^\(.[^\t]*\t.*\)\.txt\t/\1\t/
-- Remove extensions from the syntax files.  Split them into two directories
-  to avoid the 77 entry limit on old ADFS filesystems.
-- Edit "Vim:FileType" to match "*.c.*" as well as "*/c" and so on.
-  Add filetype checking too.
-- Edit "Vim:Menu" and remove all the keys from the menus: >
-	:%s/<Tab>[^ \t]*//
