8 This file contains the particularities for the RISC OS version of Vim.
|
|
|
9
|
|
|
10 The RISC OS port is a completely new port and is not based on the old `archi'
|
|
|
11 port.

|
|
|
36 *riscos-locations*
|
|
|
37 1. File locations
|
|
|
38
|
|
|
39 The Vim executable and shared resource files are all stored inside the !Vim
|
|
|
40 application directory.
|
|
|
41
|
|
|
42 When !Vim is first seen by the filer, it aliases the *vi and *ex commands to
|
|
|
43 run the command-line versions of Vim (see |riscos-commandline|).
|
|
|
44
|
|
|
45 !Vim.Resources and !Vim.Resources2 contain the files from the standard Vim
|
|
|
46 distribution, but modified slightly to work within the limits of ADFS, plus
|
|
|
47 some extra files such as the window templates.
|
|
|
48
|
|
|
49 User choices are read from `Choices:*' and are saved to `<Choices$Write>.*'.
|
|
|
50 If you have the new !Boot structure then these should be set up already. If
|
|
|
51 not, set Choices$Path to a list of directories to search when looking for
|
|
|
52 user configuration files. Set Choices$Write to the directory you want files
|
|
|
53 to be saved into (so your search patterns and marks can be remembered between
|
|
|
54 sessions).
|
|
|
55
|
|
|
56 ==============================================================================
|
|
|
57 *riscos-munging*
|
|
|
58 2. Filename munging
|
|
|
59
|
|
|
60 All pathname munging is disabled by default, so Vim should behave like a
|
|
|
61 normal RISC OS application now. So, if you want to edit `doc/html' then you
|
|
|
62 actually type `*vi doc/html'.
|
|
|
63
|
|
|
64 The only times munging is done is when:
|
|
|
65
|
|
|
66 - Searching included files from C programs, since these are always munged.
|
|
|
67 See |[I|.
|
|
|
68 Note: make sure you are in the right directory when you use this
|
|
|
69 command (i.e. the one with subdirectories 'c' and 'h').
|
|
|
70
|
|
|
71 - Sourcing files using |:so|.
|
|
|
72 Paths starting `$VIM/' are munged like this:
|
|
|
73
|
|
|
74 $VIM/syntax/help.vim -> Vim:syntax.help
|
|
|
75
|
|
|
76 Also, files ending in `.vim' have their extensions removed, and slashes
|
|
|
77 replaced with dots.
|
|
|
78
|
|
|
79 Some tag files and script files may have to be edited to work under this port.
|
|
|
80
|
|
|
81 ==============================================================================
|
|
|
82 *riscos-commandline*
|
|
|
83 3. Command-line use
|
|
|
84
|
|
|
85 To use Vim from the command-line use the `*vi' command (or '*ex' for
|
|
|
86 |Ex-mode|).
|
|
|
87
|
|
|
88 Type `*vi -h' for a list of options.
|
|
|
89
|
|
|
90 Running the command-line version of Vim in a large high-color mode may cause
|
|
|
91 the scrolling to be very slow. Either change to a mode with fewer colors or
|
|
|
92 use the GUI version.
|
|
|
93
|
|
|
94 Also, holding down Ctrl will slow it down even more, and Ctrl-Shift will
|
|
|
95 freeze it, as usual for text programs.
|
|
|
96
|
|
|
97 ==============================================================================
|
|
|
98 *riscos-gui*
|
|
|
99 4. Desktop use
|
|
|
100
|
|
|
101 Limitations:
|
|
|
102
|
|
|
103 - Left scrollbars don't work properly (right and bottom are fine).
|
|
|
104 - Doesn't increase scroll speed if it gets behind.
|
|
|
105
|
|
|
106 You can resize the window by dragging the lower-right corner, even though
|
|
|
107 there is no icon shown there.
|
|
|
108
|
|
|
109 You can use the --rows and --columns arguments to specify the initial size of
|
|
|
110 the Vim window, like this: >
|
|
|
111
|
|
|
112 *Vi -g --rows 20 --columns 80
|
|
|
113
|
|
|
114 The global clipboard is supported, so you can select some text and then
|
|
|
115 paste it directly into another application (provided it supports the
|
|
|
116 clipboard too).
|
|
|
117
|
|
|
118 Clicking Menu now opens a menu like a normal RISC OS program. Hold down Shift
|
|
|
119 when clicking Menu to paste (from the global clipboard).
|
|
|
120
|
|
|
121 Dragging a file to the window replaces the CURRENT buffer (the one with the
|
|
|
122 cursor, NOT the one you dragged to) with the file.
|
|
|
123
|
|
|
124 Dragging with Ctrl held down causes a new Vim window to be opened for the
|
|
|
125 file (see |:sp|).
|
|
|
126
|
|
|
127 Dragging a file in with Shift held down in insert mode inserts the pathname of
|
|
|
128 the file.
|
|
|
129
|
|
|
130 :browse :w opens a standard RISC OS save box.
|
|
|
131 :browse :e opens a directory viewer.
|
|
|
132
|
|
|
133 For fonts, you have the choice of the system font, an outline font, the system
|
|
|
134 font via ZapRedraw and any of the Zap fonts via ZapRedraw: >
|
|
|
135
|
|
|
136 :set guifont=
|
|
|
137 < To use the system font via the VDU drivers. Supports
|
|
|
138 bold and underline.
|
|
|
139 >
|
|
|
140 :set guifont=Corpus.Medium
|
|
|
141 < Use the named outline font. You can use any font, but
|
|
|
142 only monospaced ones like Corpus look right.
|
|
|
143 >
|
|
|
144 :set guifont=Corpus.Medium:w8:h12:b:i
|
|
|
145 < As before, but with size of 8 point by 12 point, and
|
|
|
146 in bold italic.
|
|
|
147 If only one of width and height is given then that
|
|
|
148 value is used for both. If neither is given then 10
|
|
|
149 point is used.
|
|
|
150
|
|
|
151 Thanks to John Kortink, Vim can use the ZapRedraw module. Start the font name
|
|
|
152 with '!' (or '!!' for double height), like this: >
|
|
|
153
|
|
|
154 :set guifont=!!
|
|
|
155 < Use the system font, but via ZapRedraw. This gives a
|
|
|
156 faster redraw on StrongARM processors, but you can't
|
|
|
157 get bold or italic text. Double height.
|
|
|
158 >
|
|
|
159 :set guifont=!script
|
|
|
160 < Uses the named Zap font (a directory in VimFont$Path).
|
|
|
161 The redraw is the same speed as for '!!', but you get
|
|
|
162 a nicer looking font.
|
|
|
163 Only the "man+" and "script" fonts are supplied
|
|
|
164 currently, but you can use any of the Zap fonts if
|
|
|
165 they are in VimFont$Path.
|
|
|
166 Vim will try to load font files '0', 'B', 'I' and 'IB'
|
|
|
167 from the named directory. Only '0' (normal style) MUST
|
|
|
168 be present. Link files are not currently supported.
|
|
|
169
|
|
|
170 Note that when using ZapRedraw the edit bar is drawn in front of the character
|
|
|
171 you are on rather than behind it. Also redraw is incorrect for screen modes
|
|
|
172 with eigen values of 0. If the font includes control characters then you can
|
|
|
173 get Vim to display them by changing the 'isprint' option.
|
|
|
174
|
|
|
175 If you find the scrolling is too slow on your machine, try experimenting
|
|
|
176 with the 'scrolljump' and 'ttyscroll' options.
|
|
|
177
|
|
|
178 In particular, StrongARM users may find that: >
|
|
|
179
|
|
|
180 :set ttyscroll=0
|
|
|
181
|
|
|
182 makes scrolling faster in high-color modes.
|
|
|

184 =============================================================================
|
|
|
185 *riscos-remote*
|
|
|
186 5. Remote use (telnet)
|
|
|
187
|
|
|
188 I have included a built-in termcap entry, but you can edit the termcap file to
|
|
|
189 allow other codes to be used if you want to use Vim from a remote terminal.
|
|
|
190
|
|
|
191 Although I do not have an internet connection to my Acorn, I have managed to
|
|
|
192 run Vim in a FreeTerm window using the loopback connection.
|
|
|
193
|
|
|
194 It seems to work pretty well now, using '*vi -T ansi'.
|
|
|
195
|
|
|
196 ==============================================================================
|
|
|
197 *riscos-temp-files*
|
|
|
198 6. Temporary files
|
|
|
199
|
|
|
200 If Vim crashes then the swap and backup files (if any) will be in the
|
|
|
201 directories set with the 'directory' and 'bdir' options. By default the swap
|
|
|
202 files are in <Wimp$ScrapDir> (i.e. inside !Scrap) and backups are in the
|
|
|
203 directory you were saving to. Vim will allow you to try and recover the file
|
|
|
204 when you next try to edit it.
|
|
|
205
|
|
|
206 To see a list of swap files, press <F12> and type `*vi -r'.
|
|
|
207
|
|
|
208 Vim no longer brings up ATTENTION warnings if you try to edit two files with
|
|
|
209 the same name in different directories.
|
|
|
210
|
|
|
211 However, it also no longer warns if you try to edit the same file twice (with
|
|
|
212 two copies of Vim), though you will still be warned when you save that the
|
|
|
213 datestamp has changed.
|
|
|
214
|
|
|
215 ==============================================================================
|
|
|
216 *riscos-interrupt*
|
|
|
217 7. Interrupting
|
|
|
218
|
|
|
219 To break out of a looping macro, or similar, hold down Escape in the
|
|
|
220 command-line version, or press CTRL-C in the GUI version.
|
|
|
221
|
|
|
222 ==============================================================================
|
|
|
223 *riscos-memory*
|
|
|
224 8. Memory usage
|
|
|
225
|
|
|
226 Vim will use dynamic areas on RISC OS 3.5 or later. If you can use them on
|
|
|
227 older machines then edit the !RunTxt and GVim files. I don't know what UnixLib
|
|
|
228 does by default on these machines so I'm playing safe.
|
|
|
229
|
|
|
230 It doesn't work at all well without dynamic areas, since it can't change its
|
|
|
231 memory allocation once running. Hence you should edit `!Vim.GVim' and
|
|
|
232 `!Vim.!RunTxt' to choose the best size for you. You probably need at least
|
|
|
233 about 1400K.
|
|
|
234
|
|
|
235 ==============================================================================
|
|
|
236 *riscos-filetypes*
|
|
|
237 9. Filetypes
|
|
|
238
|
|
|
239 You can now specify that autocommands are only executed for files of certain
|
|
|
240 types. The filetype is given in the form &xxx, when xxx is the filetype.
|
|
|
241
|
|
|
242 Filetypes must be specified by number (e.g. &fff for Text).
|
|
|
243
|
|
|
244 The system has changed from version 5.3. The new sequence of events is:
|
|
|
245
|
|
|
246 - A file is loaded. |'osfiletype'| is set to the RISC OS filetype.
|
|
|
247 - Based on the filetype and pathname, Vim will try to set |'filetype'| to the
|
|
|
248 Vim-type of the file.
|
|
|
249 - Setting this option may load syntax files and perform other actions.
|
|
|
250 - Saving the file will give it a filetype of |'osfiletype'|.
|
|
|
251
|
|
|
252 Some examples may make this clearer:
|
|
|
253
|
|
|
254 Kind of file loaded osfiletype filetype ~
|
|
|
255 C code 'c.hellow' Text (&fff) C
|
|
|
256 LaTeX document LaTeX (&2a8) TeX
|
|
|
257 Draw document DrawFile (&aff) (not changed)
|
|
|
258
|
|
|
259 ==============================================================================
|
|
|
260 *riscos-shell*
|
|
|
261 10. The shell
|
|
|
262
|
|
|
263 - Bangs (!s) are only replaced if they are followed by a space or end-of-line,
|
|
|
264 since many pathnames contain them.
|
|
|
265
|
|
|
266 - You can prefix the command with '~', which stops any output from being
|
|
|
267 displayed. This also means that you don't have to press <Enter> afterwards,
|
|
|
268 and stops the screen from being redrawn. {only in the GUI version}
|
|
|
269
|
|
|
270 ==============================================================================
|
|
|
271 *riscos-porting*
|
|
|
272 11. Porting new releases to RISC OS
|
|
|
273
|
|
|
274 Downloading everything you need:
|
|
|
275
|
|
|
276 - Get the latest source distribution (see www.vim.org)
|
|
|
277 - Get the runtime environment files (e.g. these help files)
|
|
|
278 - Get the `extra' archive (contains the RISC OS specific bits)
|
|
|
279 - Get the RISC OS binary distribution (if possible)
|
|
|
280
|
|
|
281
|
|
|
282 Unarchiving:
|
|
|
283
|
|
|
284 - Create a raFS disk and put the archives on it
|
|
|
285 - Un-gzip them
|
|
|
286 - Un-tar them (*tar xELf 50 archive/tar)
|
|
|
287
|
|
|
288
|
|
|
289 Recompiling the sources:
|
|
|
290
|
|
|
291 - Create c, s, and h directories.
|
|
|
292 - Put all the header files in 'h'. \
|
|
|
293 - Put all the C files in `c'. | And lose the extensions
|
|
|
294 - Put the assembler file (`swis/s') in 's'. /
|
|
|
295 - Rename all the files in `proto' to `h', like this:
|
|
|
296 raFS::VimSrc.source.proto.file/pro
|
|
|
297 becomes
|
|
|
298 raFS::VimSrc.source.h.file_pro
|
|
|
299 - In the files `h.proto' and `c.termlib', search and replace
|
|
|
300 .pro"
|
|
|
301 with
|
|
|
302 _pro.h"
|
|
|
303 - Create a simple Makefile if desired and do '*make -k'.
|
|
|
304 Use 'CC = gcc -DRISCOS -DUSE_GUI -O2 -x c' in the Makefile.
|
|
|
305 - Save the binary as !Vim.Vim in the binary distribution.
|
|
|
306
|
|
|
307
|
|
|
308 Updating the run-time environment:
|
|
|
309
|
|
|
310 - Replace old or missing files inside !Vim.Resources with the
|
|
|
311 new files.
|
|
|
312 - Remove files in `doc' not ending in `/txt', except for `tags'.
|
|
|
313 - Lose the extensions from the files in `doc'.
|
|
|
314 - Edit the `doc.tags' file. Remove extensions from the second column: >
|
|
|
315 :%s/^\(.[^\t]*\t.*\)\.txt\t/\1\t/
|
|
|
316 - Remove extensions from the syntax files. Split them into two directories
|
|
|
317 to avoid the 77 entry limit on old ADFS filesystems.
|
|
|
318 - Edit `Vim:FileType' to match `*.c.*' as well as `*/c' and so on.
|
|
|
319 Add filetype checking too.
|
|
|
320 - Edit `Vim:Menu' and remove all the keys from the menus: >
|
|
|
321 :%s/<Tab>[^ \t]*//
|
|
|
322 <
|
|
|
323 vim:tw=78:ts=8:ft=help:norl:
