7 Right to Left and Farsi Mapping for Vim *farsi* *Farsi*
9 {Vi does not have any of these commands}
11 In order to use right-to-left and Farsi mapping support, it is necessary to
12 compile Vim with the |+farsi| feature.
14 These functions have been made by Mortaza G. Shiran <shiran@jps.net>
19 In right-to-left oriented files the characters appear on the screen from right
20 to left. This kind of file is most useful when writing Farsi documents,
21 composing faxes or writing Farsi memos.
23 The commands, prompts and help files are not in Farsi, therefore the user
24 interface remains the standard Vi interface.
29 o Editing left-to-right files as in the original Vim, no change.
31 o Viewing and editing files in right-to-left windows. File orientation is
32 per window, so it is possible to view the same file in right-to-left and
33 left-to-right modes, simultaneously.
35 o Compatibility to the original Vim. Almost all features work in
36 right-to-left mode (see bugs below).
38 o Changing keyboard mapping and reverse insert modes using a single
41 o Backing from reverse insert mode to the correct place in the file
44 o While in Farsi mode, numbers are entered from left to right. Upon entering
45 a none number character, that character will be inserted just into the
46 left of the last number.
48 o No special terminal with right-to-left capabilities is required. The
49 right-to-left changes are completely hardware independent. Only
50 Farsi font is necessary.
52 o Farsi keymapping on the command line in reverse insert mode.
54 o Toggling between left-to-right and right-to-left via F8 function key.
56 o Toggling between Farsi ISIR-3342 standard encoding and VIM Farsi via F9
57 function key. Since this makes sense only for the text written in
58 right-to-left mode, this function is also supported only in right-to-left
61 Farsi Fonts *farsi fonts*
64 Following files are contained in the subdirectories of 'farsi' directory:
66 + far-a01.pcf X Windows fonts for Unix including Linux systems
67 + far-a01.bf X Windows fonts for SunOs
68 + far-a01.f16 a screen fonts for Unix including Linux systems
69 + far-a01.fon a monospaced fonts for Windows NT/95/98
70 + far-a01.com a screen fonts for DOS
76 o Installation of fonts for MS Window systems (NT/95/98)
78 From 'Control Panel' folder, start the 'Fonts' program. Then from 'file'
79 menu item select 'Install New Fonts ...'. Brows and select the
80 'far-a01.fon', then follow the installation guide.
82 o Installation of fonts for X Window systems (Unix/Linux)
84 Depending on your system, copy far-a01.pcf.Z or far-a01.pcf.gz into a
85 directory of your choice. Change to the directory containing the Farsi
86 fonts and execute the following commands:
89 > xset +fp path_name_of_farsi_fonts_directory
91 o Installation of fonts for X Window systems (SunOs)
93 Copy far-a01.bf font into a directory of your choice.
94 Change to the directory containing the far-a01.fb fonts and
95 execute the following commands:
98 > xset +fp path_name_of_fonts_directory
100 o Installation of ASCII screen fonts (Unix/Linux)
102 For Linux system, copy the far-a01.f16 fonts into /usr/lib/kbd/consolefonts
103 directory and execute the setfont program as "setfont far-a01.f16". For
104 other systems (e.g. SCO Unix), please refer to the fonts installation
105 section of your system administration manuals.
107 o Installation of ASCII screen fonts (DOS)
109 After system power on, prior to the first use of VIM, upload the Farsi
110 fonts by executing the far-a01.com font uploading program.
115 Prior to starting VIM, the environment in which VIM can run in Farsi mode,
116 must be set. In addition to installation of Farsi fonts, following points
117 refer to some of the system environments, which you may need to set:
118 Key code mapping, loading graphic card in ASCII screen mode, setting the IO
119 driver in 8 bit clean mode ... .
121 o Setting the Farsi fonts
123 + For VIM GUI set the 'guifont' to far-a01. This is done by entering
124 ':set guifont=far-a01' in the VIM window.
126 You can have 'guifont' set to far-a01 by VIM during the VIM startup
127 by appending the ':set guifont=far-a01' into your .vimrc file
128 (in case of NT/95/98 platforms _vimrc).
130 Under the X Window environment, you can also start the VIM with
131 '-fn far-a01' option.
133 + For thr VIM within a xterm, start a xterm with the Farsi fonts (e.g.
134 kterm -fn far-a01). Then start the VIM inside the kterm.
136 + For VIM under DOS, prior to the first usage of VIM, upload the Farsi
137 fonts by executing the far-a01.com fonts uploading program.
139 o Farsi Keymapping Activation
141 To activate the Farsi keymapping, set either 'altkeymap' or 'fkmap'.
142 This is done by entering ':set akm' or ':set fk' in the VIM window.
143 You can have 'altkeymap' or 'fkmap' set as default by appending ':set akm'
144 or ':set fk' in your .vimrc file or _vimrc in case of NT/95/98 platforms.
146 To turn off the Farsi kemapping as a default second language keymapping,
147 reset the 'altkeymap' by entering ':set noakm'.
149 o right-to-left Farsi Mode
151 By default VIM starts in Left-to-right mode. Following are ways to change
152 the window orientation:
154 + Start the VIM with -F option (e.g. vim -F ... ).
156 + Use F8 function key to toggle between left-to-right and right-to-left.
158 + While in Left-to-right mode, enter 'set rl' in the command line ('rl' is
159 the abbreviation for rightleft).
161 + Put the 'set rl' line in your '.vimrc' file to start the VIM in
162 right-to-left mode permanently.
167 The letter encoding used is the VIM extended ISIR-3342 standard with a built
168 in function to convert between VIM extended ISIR-3342 and ISIR-3342 standard.
170 For document portability reasons, the letter encoding is kept the same across
171 different platforms (i.e. UNIX's, NT/95/98, MS DOS, ...).
176 + CTRL-_ in insert/replace modes toggles between Farsi(akm)/Latin
179 + CTRL-_ moves the cursor to the end of the typed text in edit mode.
181 + CTRL-_ in command mode only toggles keyboard mapping between Farsi(akm)/
182 Latin. The Farsi text is then entered in reverse insert mode.
184 + F8 - Toggles between left-to-right and right-to-left.
186 + F9 - Toggles the encoding between ISIR-3342 standard and VIM extended
187 ISIR-3342 (supported only in right-to-left mode).
189 + Keyboard mapping is based on the Iranian ISIRI-2901 standard.
190 Following table shows the keyboard mapping while Farsi(akm) mode set:

226 o In insert/replace mode and fkmap (Farsi mode) set, CTRL-B is not
229 o If you change the character mapping between Latin/Farsi, the redo buffer
230 will be reset (emptied). That is, redo is valid and will function (using
231 '.') only within the mode you are in.
233 o While numbers are entered in Farsi mode, the redo buffer will be reset
234 (emptied). That is, you can not redo the last changes (using '.') after
237 o While in left-to-right and Farsi mode set, CTRL-R is not supported.
239 o While in right-to-left mode, the search on 'Latin' pattern does not work,
240 except if you enter the Latin search pattern in reverse.
242 o In the command mode, there is no support for entering the numbers from left
243 to right and also for the sake of the flexibility the keymapping logic is
246 o Under X Window environment, if you want to run the VIM within a xterm
247 terminal emulator and Farsi mode set, you need to have an ANSI compatible
248 xterm terminal emulator. This is because the letter codes above 128 decimal
249 have certain meanings in the standard xterm terminal emulator.
251 Note: Under X Window environment, VIM GUI works fine in Farsi mode.
252 This eliminates the need of any xterm terminal emulator.
257 While in insert/replace and Farsi mode set, if you repeatedly change the
258 cursor position (via cursor movement) and enter new text and then try to undo
259 the last change, the undo will lag one change behind. But as you continue to
260 undo, you will reach the original line of text. You can also use U to undo all
261 changes made in the current line.
