Right to Left and Farsi Mapping for Vim		*farsi* *Farsi*

{Vi does not have any of these commands}

In order to use right-to-left and Farsi mapping support, it is necessary to
compile Vim with the |+farsi| feature.

These functions have been made by Mortaza G. Shiran <[e-mail]>


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.

Farsi Fonts					*farsi fonts*
-----------

Following files are contained in the subdirectories of 'farsi' directory:

   +  far-a01.pcf    X Windows fonts for Unix including Linux systems
   +  far-a01.bf     X Windows fonts for SunOs
   +  far-a01.f16    a screen fonts for Unix including Linux systems
   +  far-a01.fon    a monospaced fonts for Windows NT/95/98
   +  far-a01.com    a screen fonts for DOS


Font Installation
-----------------

o  Installation of fonts for MS Window systems (NT/95/98)

   From 'Control Panel' folder, start the 'Fonts' program. Then from 'file'
   menu item select 'Install New Fonts ...'. Brows and select the
   'far-a01.fon', then follow the installation guide.

o  Installation of fonts for X Window systems (Unix/Linux)

   Depending on your system, copy far-a01.pcf.Z or far-a01.pcf.gz into a
   directory of your choice.  Change to the directory containing the Farsi
   fonts and execute the following commands:

   >  mkfontdir
   >  xset +fp path_name_of_farsi_fonts_directory

o  Installation of fonts for X Window systems (SunOs)

   Copy far-a01.bf font into a directory of your choice.
   Change to the directory containing the far-a01.fb fonts and
   execute the following commands:

   >  fldfamily
   >  xset +fp path_name_of_fonts_directory

o  Installation of ASCII screen fonts (Unix/Linux)

   For Linux system, copy the far-a01.f16 fonts into /usr/lib/kbd/consolefonts
   directory and execute the setfont program as "setfont far-a01.f16". For
   other systems (e.g. SCO Unix), please refer to the fonts installation
   section of your system administration manuals.

o  Installation of ASCII screen fonts (DOS)

   After system power on, prior to the first use of VIM, upload the Farsi
   fonts by executing the far-a01.com font uploading program.


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
      (in case of NT/95/98 platforms _vimrc).

      Under the X Window environment, you can also start the VIM with
      '-fn far-a01' option.

   +  For thr VIM within a xterm, start a xterm with the Farsi fonts (e.g.
      kterm -fn far-a01). Then start the 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 or _vimrc in case of NT/95/98 platforms.

   To turn off the Farsi kemapping 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 the VIM with -F option (e.g. vim -F ... ).

   + Use 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 the  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's, NT/95/98, MS DOS, ...).


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:
