1*hebrew.txt* For Vim version 8.2. Last change: 2019 May 05 2 3 4 VIM REFERENCE MANUAL by Ron Aaron (and Avner Lottem) 5 6 7Hebrew Language support (options & mapping) for Vim *hebrew* 8 9The supporting 'rightleft' functionality was originally created by Avner 10Lottem. <alottem at gmail dot com> Ron Aaron <ron at ronware dot org> is 11currently helping support these features. 12 13{only available when the |+rightleft| feature was enabled at compile time} 14 15 16Introduction 17------------ 18Hebrew-specific options are 'hkmap', 'hkmapp' 'keymap'=hebrew and 'aleph'. 19Hebrew-useful options are 'delcombine', 'allowrevins', 'revins', 'rightleft' 20and 'rightleftcmd'. 21 22The 'rightleft' mode reverses the display order, so characters are displayed 23from right to left instead of the usual left to right. This is useful 24primarily when editing Hebrew or other Middle-Eastern languages. 25See |rileft.txt| for further details. 26 27Details 28-------------- 29+ Options: 30 + 'rightleft' ('rl') sets window orientation to right-to-left. This means 31 that the logical text 'ABC' will be displayed as 'CBA', and will start 32 drawing at the right edge of the window, not the left edge. 33 + 'hkmap' ('hk') sets keyboard mapping to Hebrew, in insert/replace modes. 34 + 'aleph' ('al'), numeric, holds the decimal code of Aleph, for keyboard 35 mapping. 36 + 'hkmapp' ('hkp') sets keyboard mapping to 'phonetic hebrew' 37 38 NOTE: these three ('hkmap', 'hkmapp' and 'aleph') are obsolete. You should 39 use ":set keymap=hebrewp" instead. 40 41 + 'delcombine' ('deco'), boolean, if editing UTF-8 encoded Hebrew, allows 42 one to remove the niqud or te`amim by pressing 'x' on a character (with 43 associated niqud). 44 45 + 'rightleftcmd' ('rlc') makes the command-prompt for searches show up on 46 the right side. It only takes effect if the window is 'rightleft'. 47 48+ Encoding: 49 + Under Unix, ISO 8859-8 encoding (Hebrew letters codes: 224-250). 50 + Under MS DOS, PC encoding (Hebrew letters codes: 128-154). 51 These are defaults, that can be overridden using the 'aleph' option. 52 + You should prefer using UTF8, as it supports the combining-characters 53 ('deco' does nothing if UTF8 encoding is not active). 54 55+ Vim arguments: 56 + 'vim -H file' starts editing a Hebrew file, i.e. 'rightleft' and 'hkmap' 57 are set. 58 59+ Keyboard: 60 + The 'allowrevins' option enables the CTRL-_ command in Insert mode and 61 in Command-line mode. 62 63 + CTRL-_ in insert/replace modes toggles 'revins' and 'hkmap' as follows: 64 65 When in rightleft window, 'revins' and 'nohkmap' are toggled, since 66 English will likely be inserted in this case. 67 68 When in norightleft window, 'revins' 'hkmap' are toggled, since Hebrew 69 will likely be inserted in this case. 70 71 CTRL-_ moves the cursor to the end of the typed text. 72 73 + CTRL-_ in command mode only toggles keyboard mapping (see Bugs below). 74 This setting is independent of 'hkmap' option, which only applies to 75 insert/replace mode. 76 77 Note: On some keyboards, CTRL-_ is mapped to CTRL-?. 78 79 + Keyboard mapping while 'hkmap' is set (standard Israeli keyboard): 80 81 q w e r t y u i o p 82 / ' ק ר א ט ו ן ם פ 83 84 a s d f g h j k l ; ' 85 ש ד ג כ ע י ח ל ך ף , 86 87 z x c v b n m , . / 88 ז ס ב ה נ מ צ ת ץ . 89 90 This is also the keymap when 'keymap=hebrew' is set. The advantage of 91 'keymap' is that it works properly when using UTF8, e.g. it inserts the 92 correct characters; 'hkmap' does not. The 'keymap' keyboard can also 93 insert niqud and te`amim. To see what those mappings are, look at the 94 keymap file 'hebrew.vim' etc. 95 96 97Typing backwards 98 99If the 'revins' (reverse insert) option is set, inserting happens backwards. 100This can be used to type Hebrew. When inserting characters the cursor is not 101moved and the text moves rightwards. A <BS> deletes the character under the 102cursor. CTRL-W and CTRL-U also work in the opposite direction. <BS>, CTRL-W 103and CTRL-U do not stop at the start of insert or end of line, no matter how 104the 'backspace' option is set. 105 106There is no reverse replace mode (yet). 107 108If the 'showmode' option is set, "-- REVERSE INSERT --" will be shown in the 109status line when reverse Insert mode is active. 110 111When the 'allowrevins' option is set, reverse Insert mode can be also entered 112via CTRL-_, which has some extra functionality: First, keyboard mapping is 113changed according to the window orientation -- if in a left-to-right window, 114'revins' is used to enter Hebrew text, so the keyboard changes to Hebrew 115('hkmap' is set); if in a right-to-left window, 'revins' is used to enter 116English text, so the keyboard changes to English ('hkmap' is reset). Second, 117when exiting 'revins' via CTRL-_, the cursor moves to the end of the typed 118text (if possible). 119 120 121Pasting when in a rightleft window 122---------------------------------- 123When cutting text with the mouse and pasting it in a rightleft window 124the text will be reversed, because the characters come from the cut buffer 125from the left to the right, while inserted in the file from the right to 126the left. In order to avoid it, toggle 'revins' (by typing CTRL-? or CTRL-_) 127before pasting. 128 129 130Hebrew characters and the 'isprint' variable 131-------------------------------------------- 132Sometimes Hebrew character codes are in the non-printable range defined by 133the 'isprint' variable. For example in the Linux console, the Hebrew font 134encoding starts from 128, while the default 'isprint' variable is @,161-255. 135The result is that all Hebrew characters are displayed as ~x. To solve this 136problem, set isprint=@,128-255. 137 138 139 vim:tw=78:ts=8:noet:ft=help:norl: 140
