- - ==============================================================================
- - *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]*//
