patch 8.0.0475: not enough testing for the client-server feature
Problem: Not enough testing for the client-server feature.
Solution: Add more tests. Add the remote_startserver() function. Fix that
a locally evaluated expression uses function-local variables.

7 Arabic Language support (options & mappings) for Vim *Arabic* | |
8 | |
9 {Vi does not have any of these commands} | |
10 | |
11 *E800* | |
12 In order to use right-to-left and Arabic mapping support, it is | |
13 necessary to compile VIM with the |+arabic| feature. | |
14 | |
15 These functions have been created by Nadim Shaikli <nadim-at-arabeyes.org> | |
16 | |
17 It is best to view this file with these settings within VIM's GUI: > | |
18 | |
19 :set encoding=utf-8 | |
20 :set arabicshape | |
21 | |
22 | |
23 Introduction | |
24 ------------ | |
25 Arabic is a rather demanding language in which a number of special | |
26 features are required. Characters are right-to-left oriented and | |
237 | 27 ought to appear as such on the screen (i.e. from right to left). |
7 | 28 Arabic also requires shaping of its characters, meaning the same |
29 character has a different visual form based on its relative location | |
30 within a word (initial, medial, final or stand-alone). Arabic also | |
31 requires two different forms of combining and the ability, in | |
32 certain instances, to either superimpose up to two characters on top | |
33 of another (composing) or the actual substitution of two characters | |
34 into one (combining). Lastly, to display Arabic properly one will | |
35 require not only ISO-8859-6 (U+0600-U+06FF) fonts, but will also | |
36 require Presentation Form-B (U+FE70-U+FEFF) fonts both of which are | |
37 subsets within a so-called ISO-10646-1 font. | |
38 | |
39 The commands, prompts and help files are not in Arabic, therefore | |
40 the user interface remains the standard Vi interface. | |
41 | |
42 | |
43 Highlights | |
44 ---------- | |
45 o Editing left-to-right files as in the original VIM hasn't changed. | |
46 | |
47 o Viewing and editing files in right-to-left windows. File | |
48 orientation is per window, so it is possible to view the same | |
49 file in right-to-left and left-to-right modes, simultaneously. | |
50 | |
51 o No special terminal with right-to-left capabilities is required. | |
52 The right-to-left changes are completely hardware independent. | |
53 Only Arabic fonts are necessary. | |
54 | |
55 o Compatible with the original VIM. Almost all features work in | |
56 right-to-left mode (there are liable to be bugs). | |
57 | |
58 o Changing keyboard mapping and reverse insert modes using a single | |
59 command. | |
60 | |
61 o Toggling complete Arabic support via a single command. | |
62 | |
237 | 63 o While in Arabic mode, numbers are entered from left to right. Upon |
7 | 64 entering a none number character, that character will be inserted |
65 just into the left of the last number. | |
66 | |
67 o Arabic keymapping on the command line in reverse insert mode. | |
68 | |
69 o Proper Bidirectional functionality is possible given VIM is | |
70 started within a Bidi capable terminal emulator. | |
71 | |
72 | |
73 Arabic Fonts *arabicfonts* | |
74 ------------ | |
75 | |
76 VIM requires monospaced fonts of which there are many out there. | |
77 Arabic requires ISO-8859-6 as well as Presentation Form-B fonts | |
78 (without Form-B, Arabic will _NOT_ be usable). It is highly | |
79 recommended that users search for so-called 'ISO-10646-1' fonts. | |
80 Do an Internet search or check www.arabeyes.org for further | |
81 info on where to attain the necessary Arabic fonts. | |
82 | |
83 | |
84 Font Installation | |
85 ----------------- | |
86 | |
87 o Installation of fonts for X Window systems (Unix/Linux) | |
88 | |
89 Depending on your system, copy your_ARABIC_FONT file into a | |
90 directory of your choice. Change to the directory containing | |
91 the Arabic fonts and execute the following commands: | |
92 | |
93 % mkfontdir | |
94 % xset +fp path_name_of_arabic_fonts_directory | |
95 | |
96 | |
97 Usage | |
98 ----- | |
99 Prior to the actual usage of Arabic within VIM, a number of settings | |
100 need to be accounted for and invoked. | |
101 | |
102 o Setting the Arabic fonts | |
103 | |
237 | 104 + For VIM GUI set the 'guifont' to your_ARABIC_FONT. This is done |
7 | 105 by entering the following command in the VIM window. |
106 > | |
107 :set guifont=your_ARABIC_FONT | |
108 < | |
109 NOTE: the string 'your_ARABIC_FONT' is used to denote a complete | |
237 | 110 font name akin to that used in Linux/Unix systems. |
111 (e.g. -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1) | |
7 | 112 |
113 You can append the 'guifont' set command to your .vimrc file | |
114 in order to get the same above noted results. In other words, | |
115 you can include ':set guifont=your_ARABIC_FONT' to your .vimrc | |
116 file. | |
117 | |
118 + Under the X Window environment, you can also start VIM with | |
119 '-fn your_ARABIC_FONT' option. | |
120 | |
121 o Setting the appropriate character Encoding | |
122 To enable the correct Arabic encoding the following command needs | |
123 to be appended, | |
124 > | |
125 :set encoding=utf-8 | |
126 < | |
127 to your .vimrc file (entering the command manually into you VIM | |
128 window is highly discouraged). In short, include ':set | |
129 encoding=utf-8' to your .vimrc file. | |
130 | |
131 Attempts to use Arabic without UTF-8 will result the following | |
132 warning message, | |
133 | |
134 *W17* > | |
135 Arabic requires UTF-8, do ':set encoding=utf-8' | |
136 | |
137 o Enable Arabic settings [short-cut] | |
138 | |
139 In order to simplify and streamline things, you can either invoke | |
140 VIM with the command-line option, | |
141 | |
142 % vim -A my_utf8_arabic_file ... | |
143 | |
144 or enable 'arabic' via the following command within VIM | |
145 > | |
146 :set arabic | |
147 < | |
148 The two above noted possible invocations are the preferred manner | |
2642 | 149 in which users are instructed to proceed. Barring an enabled 'termbidi' |
7 | 150 setting, both command options: |
151 | |
152 1. set the appropriate keymap | |
153 2. enable the deletion of a single combined pair character | |
154 3. enable rightleft mode | |
155 4. enable rightleftcmd mode (affecting the command-line) | |
156 5. enable arabicshape mode (do visual character alterations) | |
157 | |
158 You may also append the command to your .vimrc file and simply | |
159 include ':set arabic' to it. | |
160 | |
161 You are also capable of disabling Arabic support via | |
162 > | |
163 :set noarabic | |
164 < | |
165 which resets everything that the command had enabled without touching | |
166 the global settings as they could affect other possible open buffers. | |
167 In short the 'noarabic' command, | |
168 | |
169 1. resets to the alternate keymap | |
170 2. disables the deletion of a single combined pair character | |
171 3. disables rightleft mode | |
172 | |
173 NOTE: the 'arabic' command takes into consideration 'termbidi' for | |
174 possible external bi-directional (bidi) support from the | |
175 terminal ("mlterm" for instance offers such support). | |
176 'termbidi', if available, is superior to rightleft support | |
177 and its support is preferred due to its level of offerings. | |
178 'arabic' when 'termbidi' is enabled only sets the keymap. | |
179 | |
180 If, on the other hand, you'd like to be verbose and explicit and | |
181 are opting not to use the 'arabic' short-cut command, here's what | |
237 | 182 is needed (i.e. if you use ':set arabic' you can skip this section) - |
7 | 183 |
184 + Arabic Keymapping Activation | |
185 | |
237 | 186 To activate the Arabic keymap (i.e. to remap your English/Latin |
7 | 187 keyboard to look-n-feel like a standard Arabic one), set the |
188 'keymap' command to "arabic". This is done by entering | |
189 > | |
190 :set keymap=arabic | |
191 < | |
192 in your VIM window. You can also append the 'keymap' set command to | |
193 your .vimrc file. In other words, you can include ':set keymap=arabic' | |
194 to your .vimrc file. | |
195 | |
196 To turn toggle (or switch) your keymapping between Arabic and the | |
197 default mapping (English), it is advised that users use the 'CTRL-^' | |
198 key press while in insert (or add/replace) mode. The command-line | |
199 will display your current mapping by displaying an "Arabic" string | |
237 | 200 next to your insertion mode (e.g. -- INSERT Arabic --) indicating |
7 | 201 your current keymap. |
202 | |
203 + Arabic deletion of a combined pair character | |
204 | |
205 By default VIM has the 'delcombine' option disabled. This option | |
206 allows the deletion of ALEF in a LAM_ALEF (LAA) combined character | |
237 | 207 and still retain the LAM (i.e. it reverts to treating the combined |
7 | 208 character as its natural two characters form -- this also pertains |
209 to harakat and their combined forms). You can enable this option | |
210 by entering | |
211 > | |
212 :set delcombine | |
213 < | |
214 in our VIM window. You can also append the 'delcombine' set command | |
215 to your .vimrc file. In other words, you can include ':set delcombine' | |
216 to your .vimrc file. | |
217 | |
218 + Arabic right-to-left Mode | |
219 | |
220 By default VIM starts in Left-to-right mode. 'rightleft' is the | |
221 command that allows one to alter a window's orientation - that can | |
222 be accomplished via, | |
223 | |
224 - Toggling between left-to-right and right-to-left modes is | |
225 accomplished through ':set rightleft' and ':set norightleft'. | |
226 | |
227 - While in Left-to-right mode, enter ':set rl' in the command line | |
228 ('rl' is the abbreviation for rightleft). | |
229 | |
237 | 230 - Put the ':set rl' line in your '.vimrc' file to start Vim in |
7 | 231 right-to-left mode permanently. |
232 | |
233 + Arabic right-to-left command-line Mode | |
234 | |
235 For certain commands the editing can be done in right-to-left mode. | |
236 Currently this is only applicable to search commands. | |
237 | |
238 This is controlled with the 'rightleftcmd' option. The default is | |
239 "search", which means that windows in which 'rightleft' is set will | |
240 edit search commands in right-left mode. To disable this behavior, | |
241 > | |
242 :set rightleftcmd= | |
243 < | |
244 To enable right-left editing of search commands again, | |
245 > | |
246 :set rightleftcmd& | |
247 < | |
248 + Arabic Shaping Mode | |
249 | |
250 To activate the required visual characters alterations (shaping, | |
251 composing, combining) which the Arabic language requires, enable | |
252 the 'arabicshape' command. This is done by entering | |
253 > | |
254 :set arabicshape | |
255 < | |
256 in our VIM window. You can also append the 'arabicshape' set | |
257 command to your .vimrc file. In other words, you can include | |
258 ':set arabicshape' to your .vimrc file. | |
259 | |
260 | |
261 Keymap/Keyboard *arabickeymap* | |
262 --------------- | |
263 | |
264 The character/letter encoding used in VIM is the standard UTF-8. | |
265 It is widely discouraged that any other encoding be used or even | |
266 attempted. | |
267 | |
268 Note: UTF-8 is an all encompassing encoding and as such is | |
269 the only supported (and encouraged) encoding with | |
270 regard to Arabic (all other proprietary encodings | |
271 should be discouraged and frowned upon). | |
272 | |
273 o Keyboard | |
274 | |
275 + CTRL-^ in insert/replace mode toggles between Arabic/Latin mode | |
276 | |
277 + Keyboard mapping is based on the Microsoft's Arabic keymap (the | |

294 Restrictions | |
295 ------------ | |
296 | |
297 o VIM in its GUI form does not currently support Bi-directionality | |
237 | 298 (i.e. the ability to see both Arabic and Latin intermixed within |
7 | 299 the same line). |
300 | |
301 | |
302 Known Bugs | |
303 ---------- | |
304 | |
305 There is one known minor bug, | |
306 | |
237 | 307 1. If you insert a haraka (e.g. Fatha (U+064E)) after a LAM (U+0644) |
7 | 308 and then insert an ALEF (U+0627), the appropriate combining will |
309 not happen due to the sandwiched haraka resulting in something | |
310 that will NOT be displayed correctly. | |
311 | |
312 WORK-AROUND: Don't include harakats between LAM and ALEF combos. | |
313 In general, don't anticipate to see correct visual | |
314 representation with regard to harakats and LAM+ALEF | |
315 combined characters (even those entered after both | |
316 characters). The problem noted is strictly a visual | |
317 one, meaning saving such a file will contain all the | |
318 appropriate info/encodings - nothing is lost. | |
319 | |
320 No other bugs are known to exist. | |
