7 Right to Left and Farsi Mapping for Vim *farsi* *Farsi*
9 {Vi does not have any of these commands}
12 In order to use right-to-left and Farsi mapping support, it is necessary to
13 compile Vim with the |+farsi| feature.
15 These functions have been made by Mortaza G. Shiran <shiran@jps.net>
20 In right-to-left oriented files the characters appear on the screen from right
21 to left. This kind of file is most useful when writing Farsi documents,
22 composing faxes or writing Farsi memos.
24 The commands, prompts and help files are not in Farsi, therefore the user
25 interface remains the standard Vi interface.
30 o Editing left-to-right files as in the original Vim, no change.
32 o Viewing and editing files in right-to-left windows. File orientation is
33 per window, so it is possible to view the same file in right-to-left and
34 left-to-right modes, simultaneously.
36 o Compatibility to the original Vim. Almost all features work in
37 right-to-left mode (see bugs below).
39 o Changing keyboard mapping and reverse insert modes using a single
42 o Backing from reverse insert mode to the correct place in the file
45 o While in Farsi mode, numbers are entered from left to right. Upon entering
46 a none number character, that character will be inserted just into the
47 left of the last number.
49 o No special terminal with right-to-left capabilities is required. The
50 right-to-left changes are completely hardware independent. Only
51 Farsi font is necessary.
53 o Farsi keymapping on the command line in reverse insert mode.
55 o Toggling between left-to-right and right-to-left via F8 function key.
57 o Toggling between Farsi ISIR-3342 standard encoding and Vim Farsi via F9
58 function key. Since this makes sense only for the text written in
59 right-to-left mode, this function is also supported only in right-to-left
62 Farsi Fonts *farsi fonts*
65 The following files are found in the subdirectories of the '$VIM/farsi/fonts'
68 + far-a01.pcf X Windows fonts for Unix including Linux systems
69 + far-a01.bf X Windows fonts for SunOS
70 + far-a01.f16 a screen fonts for Unix including Linux systems
71 + far-a01.fon a monospaced fonts for Windows NT/95/98
72 + far-a01.com a screen fonts for DOS
78 o Installation of fonts for MS Window systems (NT/95/98)
80 From 'Control Panel' folder, start the 'Fonts' program. Then from 'file'
81 menu item select 'Install New Fonts ...'. Browse and select the
82 'far-a01.fon', then follow the installation guide.
83 NOTE: several people have reported that this does not work. The solution
86 o Installation of fonts for X Window systems (Unix/Linux)
88 Depending on your system, copy far-a01.pcf.Z or far-a01.pcf.gz into a
89 directory of your choice. Change to the directory containing the Farsi
90 fonts and execute the following commands:
93 > xset +fp path_name_of_farsi_fonts_directory
95 o Installation of fonts for X Window systems (SunOS)
97 Copy far-a01.bf font into a directory of your choice.
98 Change to the directory containing the far-a01.fb fonts and
99 execute the following commands:
102 > xset +fp path_name_of_fonts_directory
104 o Installation of ASCII screen fonts (Unix/Linux)
106 For Linux system, copy the far-a01.f16 fonts into /usr/lib/kbd/consolefonts
107 directory and execute the setfont program as "setfont far-a01.f16". For
108 other systems (e.g. SCO Unix), please refer to the fonts installation
109 section of your system administration manuals.
111 o Installation of ASCII screen fonts (DOS)
113 After system power on, prior to the first use of Vim, upload the Farsi
114 fonts by executing the far-a01.com font uploading program.
119 Prior to starting Vim, the environment in which Vim can run in Farsi mode,
120 must be set. In addition to installation of Farsi fonts, following points
121 refer to some of the system environments, which you may need to set:
122 Key code mapping, loading graphic card in ASCII screen mode, setting the IO
123 driver in 8 bit clean mode ... .
125 o Setting the Farsi fonts
127 + For Vim GUI set the 'guifont' to far-a01. This is done by entering
128 ':set guifont=far-a01' in the Vim window.
130 You can have 'guifont' set to far-a01 by Vim during the Vim startup
131 by appending the ':set guifont=far-a01' into your .vimrc file
132 (in case of NT/95/98 platforms _vimrc).
134 Under the X Window environment, you can also start Vim with the
135 '-fn far-a01' option.
137 + For Vim within a xterm, start a xterm with the Farsi fonts (e.g.
138 kterm -fn far-a01). Then start Vim inside the kterm.
140 + For Vim under DOS, prior to the first usage of Vim, upload the Farsi
141 fonts by executing the far-a01.com fonts uploading program.
143 o Farsi Keymapping Activation
145 To activate the Farsi keymapping, set either 'altkeymap' or 'fkmap'.
146 This is done by entering ':set akm' or ':set fk' in the Vim window.
147 You can have 'altkeymap' or 'fkmap' set as default by appending ':set akm'
148 or ':set fk' in your .vimrc file or _vimrc in case of NT/95/98 platforms.
150 To turn off the Farsi keymapping as a default second language keymapping,
151 reset the 'altkeymap' by entering ':set noakm'.
153 o right-to-left Farsi Mode
155 By default Vim starts in Left-to-right mode. Following are ways to change
156 the window orientation:
158 + Start Vim with the -F option (e.g. vim -F ...).
160 + Use the F8 function key to toggle between left-to-right and right-to-left.
162 + While in Left-to-right mode, enter 'set rl' in the command line ('rl' is
163 the abbreviation for rightleft).
165 + Put the 'set rl' line in your '.vimrc' file to start Vim in
166 right-to-left mode permanently.
171 The letter encoding used is the Vim extended ISIR-3342 standard with a built
172 in function to convert between Vim extended ISIR-3342 and ISIR-3342 standard.
174 For document portability reasons, the letter encoding is kept the same across
175 different platforms (i.e. UNIX's, NT/95/98, MS DOS, ...).
180 + CTRL-_ in insert/replace modes toggles between Farsi(akm)/Latin
183 + CTRL-_ moves the cursor to the end of the typed text in edit mode.
185 + CTRL-_ in command mode only toggles keyboard mapping between Farsi(akm)/
186 Latin. The Farsi text is then entered in reverse insert mode.
188 + F8 - Toggles between left-to-right and right-to-left.
190 + F9 - Toggles the encoding between ISIR-3342 standard and Vim extended
191 ISIR-3342 (supported only in right-to-left mode).
193 + Keyboard mapping is based on the Iranian ISIRI-2901 standard.
194 Following table shows the keyboard mapping while Farsi(akm) mode set:

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