| 7 Right to Left and Farsi Mapping for Vim *farsi* *Farsi* | |
| 8 | |
| 9 {Vi does not have any of these commands} | |
| 10 | |
| 11 *E27* | |
| 12 In order to use right-to-left and Farsi mapping support, it is necessary to | |
| 13 compile Vim with the |+farsi| feature. | |
| 14 | |
| 15 These functions have been made by Mortaza G. Shiran <shiran@jps.net> | |
| 16 | |
| 17 | |
| 18 Introduction | |
| 19 ------------ | |
| 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. | |
| 23 | |
| 24 The commands, prompts and help files are not in Farsi, therefore the user | |
| 25 interface remains the standard Vi interface. | |
| 26 | |
| 27 | |
| 28 Highlights | |
| 29 ---------- | |
| 30 o Editing left-to-right files as in the original Vim, no change. | |
| 31 | |
| 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. | |
| 35 | |
| 36 o Compatibility to the original Vim. Almost all features work in | |
| 37 right-to-left mode (see bugs below). | |
| 38 | |
| 39 o Changing keyboard mapping and reverse insert modes using a single | |
| 40 command. | |
| 41 | |
| 42 o Backing from reverse insert mode to the correct place in the file | |
| 43 (if possible). | |
| 44 | |
| 237 | 45 o While in Farsi mode, numbers are entered from left to right. Upon entering |
| 7 | 46 a none number character, that character will be inserted just into the |
| 47 left of the last number. | |
| 48 | |
| 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. | |
| 52 | |
| 53 o Farsi keymapping on the command line in reverse insert mode. | |
| 54 | |
| 55 o Toggling between left-to-right and right-to-left via F8 function key. | |
| 56 | |
| 237 | 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 | |
| 7 | 59 right-to-left mode, this function is also supported only in right-to-left |
| 60 mode. | |

| 75 Font Installation | |
| 76 ----------------- | |
| 77 | |
| 78 o Installation of fonts for MS Window systems (NT/95/98) | |
| 79 | |
| 237 | 80 From 'Control Panel' folder, start the 'Fonts' program. Then from 'file' |
| 81 menu item select 'Install New Fonts ...'. Browse and select the | |
| 7 | 82 'far-a01.fon', then follow the installation guide. |
| 83 NOTE: several people have reported that this does not work. The solution | |
| 84 is unknown. | |
| 85 | |
| 86 o Installation of fonts for X Window systems (Unix/Linux) | |
| 87 | |
| 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: | |
| 91 | |
| 92 > mkfontdir | |
| 93 > xset +fp path_name_of_farsi_fonts_directory | |
| 94 | |
| 9 | 95 o Installation of fonts for X Window systems (SunOS) |
| 7 | 96 |
| 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: | |
| 100 | |
| 101 > fldfamily | |
| 102 > xset +fp path_name_of_fonts_directory | |
| 103 | |
| 104 o Installation of ASCII screen fonts (Unix/Linux) | |
| 105 | |
| 106 For Linux system, copy the far-a01.f16 fonts into /usr/lib/kbd/consolefonts | |
| 237 | 107 directory and execute the setfont program as "setfont far-a01.f16". For |
| 7 | 108 other systems (e.g. SCO Unix), please refer to the fonts installation |
| 109 section of your system administration manuals. | |
| 110 | |
| 111 o Installation of ASCII screen fonts (DOS) | |
| 112 | |
| 237 | 113 After system power on, prior to the first use of Vim, upload the Farsi |
| 7 | 114 fonts by executing the far-a01.com font uploading program. |
| 115 | |
| 116 | |
| 117 Usage | |
| 118 ----- | |
| 237 | 119 Prior to starting Vim, the environment in which Vim can run in Farsi mode, |
| 7 | 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 ... . | |
| 124 | |
| 125 o Setting the Farsi fonts | |
| 126 | |
| 237 | 127 + For Vim GUI set the 'guifont' to far-a01. This is done by entering |
| 128 ':set guifont=far-a01' in the Vim window. | |
| 7 | 129 |
| 237 | 130 You can have 'guifont' set to far-a01 by Vim during the Vim startup |
| 7 | 131 by appending the ':set guifont=far-a01' into your .vimrc file |
| 132 (in case of NT/95/98 platforms _vimrc). | |
| 133 | |
| 237 | 134 Under the X Window environment, you can also start Vim with the |
| 7 | 135 '-fn far-a01' option. |
| 136 | |
| 237 | 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. | |
| 7 | 139 |
| 237 | 140 + For Vim under DOS, prior to the first usage of Vim, upload the Farsi |
| 7 | 141 fonts by executing the far-a01.com fonts uploading program. |
| 142 | |
| 143 o Farsi Keymapping Activation | |
| 144 | |
| 145 To activate the Farsi keymapping, set either 'altkeymap' or 'fkmap'. | |
| 237 | 146 This is done by entering ':set akm' or ':set fk' in the Vim window. |
| 7 | 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. | |
| 149 | |
| 150 To turn off the Farsi keymapping as a default second language keymapping, | |
| 151 reset the 'altkeymap' by entering ':set noakm'. | |
| 152 | |
| 153 o right-to-left Farsi Mode | |
| 154 | |
| 237 | 155 By default Vim starts in Left-to-right mode. Following are ways to change |
| 7 | 156 the window orientation: |
| 157 | |
| 237 | 158 + Start Vim with the -F option (e.g. vim -F ...). |
| 7 | 159 |
| 237 | 160 + Use the F8 function key to toggle between left-to-right and right-to-left. |
| 7 | 161 |
| 162 + While in Left-to-right mode, enter 'set rl' in the command line ('rl' is | |
| 163 the abbreviation for rightleft). | |
| 164 | |
| 237 | 165 + Put the 'set rl' line in your '.vimrc' file to start Vim in |
| 7 | 166 right-to-left mode permanently. |
| 167 | |
| 168 Encoding | |
| 169 -------- | |
| 170 | |
| 237 | 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. | |
| 7 | 173 |
| 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, ...). | |
| 176 | |
| 177 | |
| 178 o Keyboard | |
| 179 | |
| 180 + CTRL-_ in insert/replace modes toggles between Farsi(akm)/Latin | |
| 181 mode as follows: | |
| 182 | |
| 183 + CTRL-_ moves the cursor to the end of the typed text in edit mode. | |
| 184 | |
| 185 + CTRL-_ in command mode only toggles keyboard mapping between Farsi(akm)/ | |
| 237 | 186 Latin. The Farsi text is then entered in reverse insert mode. |
| 7 | 187 |
| 188 + F8 - Toggles between left-to-right and right-to-left. | |
| 189 | |
| 237 | 190 + F9 - Toggles the encoding between ISIR-3342 standard and Vim extended |
| 7 | 191 ISIR-3342 (supported only in right-to-left mode). |
| 192 | |
| 193 + Keyboard mapping is based on the Iranian ISIRI-2901 standard. | |
| 194 Following table shows the keyboard mapping while Farsi(akm) mode set: | |

| 221 | |
| 222 Note: | |
| 223 ¡ stands for Farsi PSP (break without space) | |
| 224 | |
| 6530 | 225 ¢ stands for Farsi PCN (for HAMZE attribute) |
| 7 | 226 |
| 227 Restrictions | |
| 228 ------------ | |
| 229 | |
| 230 o In insert/replace mode and fkmap (Farsi mode) set, CTRL-B is not | |
| 231 supported. | |
| 232 | |
| 233 o If you change the character mapping between Latin/Farsi, the redo buffer | |
| 237 | 234 will be reset (emptied). That is, redo is valid and will function (using |
| 7 | 235 '.') only within the mode you are in. |
| 236 | |
| 237 o While numbers are entered in Farsi mode, the redo buffer will be reset | |
| 237 | 238 (emptied). That is, you cannot redo the last changes (using '.') after |
| 7 | 239 entering numbers. |
| 240 | |
| 237 | 241 o While in left-to-right mode and Farsi mode set, CTRL-R is not supported. |
| 7 | 242 |
| 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. | |
| 245 | |
| 237 | 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 | |
| 7 | 248 restricted. |
| 249 | |
| 237 | 250 o Under the X Window environment, if you want to run Vim within a xterm |
| 7 | 251 terminal emulator and Farsi mode set, you need to have an ANSI compatible |
| 237 | 252 xterm terminal emulator. This is because the letter codes above 128 decimal |
| 7 | 253 have certain meanings in the standard xterm terminal emulator. |
| 254 | |
| 237 | 255 Note: Under X Window environment, Vim GUI works fine in Farsi mode. |
| 7 | 256 This eliminates the need of any xterm terminal emulator. |
| 257 | |
| 258 | |
| 259 Bugs | |
| 260 ---- | |
| 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 | |
| 237 | 264 undo, you will reach the original line of text. You can also use U to undo all |
| 7 | 265 changes made in the current line. |
| 266 | |
