;;; Commentary:
;;
;; This file contains a collection of input methods for
;; Persian languages (Farsi, Urdu, Pashto/Afghanic, ...)
;;
;; At this time, the following input methods are specified:
;;
;;  - (farsi-isiri-9149) Persian Keyboard based on Islamic Republic of Iran's ISIRI-9147
;;  - (farsi-transliterate-banan) An intuitive transliteration keyboard for Farsi
;;
;; Additional documentation for these input methods can be found at:
;;  http://www.persoarabic.org/PLPC/120036

;; The keyboard mapping defined here is based on:

;; Institute of Standards and Industrial Research of Iran
;; Information Technology – Layout of Persian Letters and Symbols

;; Re-Published at: http://www.persoarabic.org/Repub/fpf-isiri-9147

;; Specification of Iran's Persian Character Set is also relevant:

;;
;; Layers 1, 2 and 3 of ISIRI-9147 are fully implemented with the
;; exception of the Backslash, Alt-Backslash, Shift-Space and
;; Alt-Space keys.
;;
;; The Backslash key is used to replace کلید با دگر ساز راست‌ -- the Alt or
;; Meta key.
;;
;; Layer 3 is then entered with the Backslash key and Layer 3 is
;; implemented as two letter keys as specified in ISIRI-9147.
;;
;; The character corresponding to Backslash is entered with Backslash-Backslash.
;; Alt-Backslash has been moved to Backslash-r.
;; Alt-Space has been moved to Backslash-t.
;; Shift-Space has been moved to Backslash-y.
;;
;; With these modifications, farsi-isiri-9147 is a full implementation
;; of ISIRI-9147.  Additionally, these modifications allow for this
;; implementation to be ascii input stream based -- in addition to
;; being a keyboard layout.
;;
;; If a key on Layer 1 was reserved to replace دگر ساز راست‌ (the Alt
;; or Meta key), then farsi-isiri-9147 could have claimed full
;; compliance -- without the need for the above description. Perhaps
;; this can be considered a flaw in the base ISIRI-9147 specification
;; to be addressed in the next revision.

;; farsi-transliterate-banan
;;
;; Given a Qwerty keyboard, use Persian-to-Latin transliteration knowledge
;; to reverse transliterate in persian
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;
;;;  See http://www.persoarabic.org/PLPC/120036 document for more complete
;;;  documentation of keyboard bindings and usage instructions.
;;;
;;
;; ISIRI-9147 Persian keyboard is generally not well suited for Iranian-Expatriates
;; working/living in the West.
;;
;; The qwerty keyboard is usually second nature to Persian speaking expatriates and they
;; don't want to learn/adapt to ISIRI-9147.  They expect software to adapt to them.
;;
;; That is what the ``Banan Multi-Character (Reverse) Transliteration Persian Input Method'' does.
;;
;; The typical profile of the user is assumed to be one who:
;;
;;  -  can write in farsi (not just speak it).
;;  -  is fully comfortable with a qwerty latin keyboard.
;;  -  is not familiar with isir-9147 and does not wish to be trained.
;;  -  communicates and writes in a mixed globish/persian -- not pure persian.
;;  -  is intuitively familiar with transliteration of farsi/persian into latin based on two letter
;;     phonetic mapping to persian characters (e.g., gh ق --  kh خ -- sh ش -- ch چ -- zh ژ.
;;
;; This transliteration keyboard is designed to be intuitive such that
;; mapping are easy and natural to remember for a persian writer.
;; It is designed to be equivalent in capability to farsi-isiri-9147
;; and provide for inputting all characters enumerated in ISIRI-6219.
;;
;; farsi-transliterate-banan is of course phonetic oriented.  But it is very different from
;; pinglish. Pinglish is word oriented where you sound out the word with latin letters --
;; including the vowels. farsi-transliterate-banan is letter oriented where you enter the
;; latin letter/letters closest to the persian letter. And usually omit vowels.
;;
;; For some persian characters there are multiple ways of inputting
;; the same character. For example both ``i'' and ``y'' produce ی.
;; For یک ``yk'', ``y'' is more natural and for این ``ain'', ``i'' is more natural.
;;
;; The more frequently used keys are mapped to lower case. The less frequently used letter moves to
;; upper case. For example: ``s'' is س and ``S'' is ص.  ``h'' is ه and ``H''
;; is ح.
;;
;; Multi-character input is based on \, &, and / prefix
;; characters. The letter 'h' is used as a postfix for the following two character mappings:
;; gh ق --  kh خ -- sh ش -- ch چ -- zh ژ  -- Th ة -- Yh ى.
;;
;;
;; Prefix letter \ is used for two character inputs when an alternate form of a letter
;; is desired for example '\-' is: '÷' when '-' is: '-'.
;;
;; Prefix letter & is used for multi-character inputs when special characters are
;; desired based on their abbreviate name. For example you can enter &lrm; to enter the
;; ``LEFT-TO-RIGHT MARK'' character.
;;
;; Prefix letter / is used to provide two characters. / is: ``ZERO WIDTH NON-JOINER''
;; and // is /.
;;
;; The letter 'h' is used in a number of two character postfix mappings,
;; for example ``sh'' ش. So if you need the sequence of ``s'' and ``h'' you
;; need to repeat the ``s''. For example: سهم = 's' 's' 'h' 'm'.
