+
+
+ *riscos* *RISCOS* *RISC-OS*
+! This file contains the particularities for the RISC OS version of Vim.
+
+- The RISC OS port is a completely new port and is not based on the old "archi"
+- port.
+
+- 1. File locations |riscos-locations|
+- 2. Filename munging |riscos-munging|
+- 3. Command-line use |riscos-commandline|
+- 4. Desktop (GUI) use |riscos-gui|
+- 5. Remote use (telnet) |riscos-remote|
+- 6. Temporary files |riscos-temp-files|
+- 7. Interrupting |riscos-interrupt|
+- 8. Memory usage |riscos-memory|
+- 9. Filetypes |riscos-filetypes|
+- 10. The shell |riscos-shell|
+- 11. Porting new releases |riscos-porting|
+-
+- If I've missed anything, email me and I'll try to fix it. In fact, even if I
+- haven't missed anything then email me anyway to give me some confidence that it
+- actually works!

+- Port homepage: http://www.ecs.soton.ac.uk/~tal197/
+- or try: http://www.soton.ac.uk/~tal197/
+-
+- ==============================================================================
+- *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]*//
