- * 'gui.c' all changes are limited to this file, 'gui_riscos.c'. The change in
- * 'gui.c' is to make Vim stop being 'smart' not redrawing characters that are
- * 'already there' (i.e. from the previous line, by coincidence). This caused a
- * lot more calls to the redraw code, which we want to avoid because a few nice
- * big strings at a time is a lot faster than a truckload of small ones. ('Dear

! *os_risc.txt* For Vim version 7.3. Last change: 2010 Aug 07
VIM REFERENCE MANUAL by Thomas Leonard
*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]*//
