Shiran <shiran@jps.net> - - -Introduction ------------- -In right-to-left oriented files the characters appear on the screen from right -to left. This kind of file is most useful when writing Farsi documents, -composing faxes or writing Farsi memos. - -The commands, prompts and help files are not in Farsi, therefore the user -interface remains the standard Vi interface. - - -Highlights ----------- -o Editing left-to-right files as in the original Vim, no change. - -o Viewing and editing files in right-to-left windows. File orientation is - per window, so it is possible to view the same file in right-to-left and - left-to-right modes, simultaneously. - -o Compatibility to the original Vim. Almost all features work in - right-to-left mode (see bugs below). - -o Changing keyboard mapping and reverse insert modes using a single - command. - -o Backing from reverse insert mode to the correct place in the file - (if possible). - -o While in Farsi mode, numbers are entered from left to right. Upon entering - a none number character, that character will be inserted just into the - left of the last number. - -o No special terminal with right-to-left capabilities is required. The - right-to-left changes are completely hardware independent. Only - Farsi font is necessary. - -o Farsi keymapping on the command line in reverse insert mode. - -o Toggling between left-to-right and right-to-left via F8 function key. - -o Toggling between Farsi ISIR-3342 standard encoding and Vim Farsi via F9 - function key. Since this makes sense only for the text written in - right-to-left mode, this function is also supported only in right-to-left - mode. - - -Usage ------ -Prior to starting Vim, the environment in which Vim can run in Farsi mode, -must be set. In addition to installation of Farsi fonts, following points -refer to some of the system environments, which you may need to set: -Key code mapping, loading graphic card in ASCII screen mode, setting the IO -driver in 8 bit clean mode ... . - -o Setting the Farsi fonts - - + For Vim GUI set the 'guifont' to far-a01. This is done by entering - ':set guifont=far-a01' in the Vim window. - - You can have 'guifont' set to far-a01 by Vim during the Vim startup - by appending the ':set guifont=far-a01' into your vimrc file. - - Under the X Window environment, you can also start Vim with the - '-fn far-a01' option. - - + For Vim within a xterm, start a xterm with the Farsi fonts (e.g. - kterm -fn far-a01). Then start Vim inside the kterm. - - + For Vim under DOS, prior to the first usage of Vim, upload the Farsi - fonts by executing the far-a01.com fonts uploading program. - -o Farsi Keymapping Activation - - To activate the Farsi keymapping, set either 'altkeymap' or 'fkmap'. - This is done by entering ':set akm' or ':set fk' in the Vim window. - You can have 'altkeymap' or 'fkmap' set as default by appending ':set akm' - or ':set fk' in your vimrc file. - - To turn off the Farsi keymapping as a default second language keymapping, - reset the 'altkeymap' by entering ':set noakm'. - -o right-to-left Farsi Mode - - By default Vim starts in Left-to-right mode. Following are ways to change - the window orientation: - - + Start Vim with the -F option (e.g. vim -F ...). - - + Use the F8 function key to toggle between left-to-right and right-to-left. - - + While in Left-to-right mode, enter 'set rl' in the command line ('rl' is - the abbreviation for rightleft). - - + Put the 'set rl' line in your vimrc file to start Vim in right-to-left - mode permanently. - -Encoding --------- - -The letter encoding used is the Vim extended ISIR-3342 standard with a built -in function to convert between Vim extended ISIR-3342 and ISIR-3342 standard. - -For document portability reasons, the letter encoding is kept the same across -different platforms (i.e. Unix, Windows, ...). - - -o Keyboard - - + CTRL-_ in insert/replace modes toggles between Farsi(akm)/Latin - mode as follows: - - + CTRL-_ moves the cursor to the end of the typed text in edit mode. - - + CTRL-_ in command mode only toggles keyboard mapping between Farsi(akm)/ - Latin. The Farsi text is then entered in reverse insert mode. - - + F8 - Toggles between left-to-right and right-to-left. - - + F9 - Toggles the encoding between ISIR-3342 standard and Vim extended - ISIR-3342 (supported only in right-to-left mode). - - + Keyboard mapping is based on the Iranian ISIRI-2901 standard. - Following table shows the keyboard mapping while Farsi(akm) mode set: - - ------------------------------------- - ` 1 2 3 4 5 6 7 8 9 0 - = - ¢ ± ² ³ ´ µ ¶ · ¸ ¹ ° ½ - ------------------------------------- - ~ ! @ # $ % ^ & * ( ) _ + - ~ £ § ® ¤ ¥ ª ¬ è ¨ © é « - ------------------------------------- - q w e r t z u i o p [ ] - Ó Ò Æ Ù Ø Õ Ö à Ê É Ç ˆ - ------------------------------------- - Q W E R T Z U I O P { } - ÷ õ ô ó ò ý ð ö [ ] { } - ------------------------------------- - a s d f g h j k l ; ' \ - Ñ Ð á Ã Ü Á Å Þ Ý Ú Û ë - ------------------------------------- - A S D F G H J K L : " | - ù û þ ú ø À ü æ ç º » ê - ------------------------------------- - < y x c v b n m , . / - ¾ × Ô Î Í Ì Ë Ä ß ¦ ¯ - ------------------------------------- - > Y X C V B N M < > ? - ¼ ñ Ô Ï Í ¡ Ë Â ¾ ¼ ¿ - ------------------------------------- - -Note: - ¡ stands for Farsi PSP (break without space) - - ¢ stands for Farsi PCN (for HAMZE attribute) - -Restrictions ------------- - -o In insert/replace mode and fkmap (Farsi mode) set, CTRL-B is not - supported. - -o If you change the character mapping between Latin/Farsi, the redo buffer - will be reset (emptied). That is, redo is valid and will function (using - '.') only within the mode you are in. - -o While numbers are entered in Farsi mode, the redo buffer will be reset - (emptied). That is, you cannot redo the last changes (using '.') after - entering numbers. - -o While in left-to-right mode and Farsi mode set, CTRL-R is not supported. - -o While in right-to-left mode, the search on 'Latin' pattern does not work, - except if you enter the Latin search pattern in reverse. - -o In command mode there is no support for entering numbers from left - to right and also for the sake of flexibility the keymapping logic is - restricted. - -o Under the X Window environment, if you want to run Vim within a xterm - terminal emulator and Farsi mode set, you need to have an ANSI compatible - xterm terminal emulator. This is because the letter codes above 128 decimal - have certain meanings in the standard xterm terminal emulator. - - Note: Under X Window environment, Vim GUI works fine in Farsi mode. - This eliminates the need of any xterm terminal emulator. - - -Bugs ----- -While in insert/replace and Farsi mode set, if you repeatedly change the -cursor position (via cursor movement) and enter new text and then try to undo -the last change, the undo will lag one change behind. But as you continue to -undo, you will reach the original line of text. You can also use U to undo all -changes made in the current line. - -For more information about the bugs refer to rileft.txt. - - vim:tw=78:ts=8:noet:ft=help:norl: |
