&quot; This Vim script is used for detecting if a translation of the
&quot; tutor file exist, i.e., a tutor.xx file, where xx is the language.
&quot; If the translation does not exist, or no extension is given,
&quot; it defaults to the English version.

&quot; It is invoked by the vimtutor shell script.

&quot; 1. Build the extension of the file, if any:
let s:ext = &quot;&quot;
if strlen($xx) &gt; 1
  let s:ext = &quot;.&quot; . $xx
else
  let s:lang = &quot;&quot;
  &quot; Check that a potential value has at least two letters.
  &quot; Ignore &quot;1043&quot; and &quot;C&quot;.
  if exists(&quot;v:lang&quot;) &amp;&amp; v:lang =~ '\a\a'
    let s:lang = v:lang
  elseif $LC_ALL =~ '\a\a'
    let s:lang = $LC_ALL
  elseif $LANG =~ '\a\a'
    let s:lang = $LANG
  endif
  if s:lang != &quot;&quot;
    &quot; Remove &quot;@euro&quot; (ignoring case), it may be at the end
    let s:lang = substitute(s:lang, '\c@euro', '', '')
    &quot; On MS-Windows it may be German_Germany.1252 or Polish_Poland.1250.  How
    &quot; about other languages?
    if s:lang =~ &quot;German&quot;
      let s:ext = &quot;.de&quot;
    elseif s:lang =~ &quot;Polish&quot;
      let s:ext = &quot;.pl&quot;
    elseif s:lang =~ &quot;Slovak&quot;
      let s:ext = &quot;.sk&quot;
    elseif s:lang =~ &quot;Serbian&quot;
      let s:ext = &quot;.sr&quot;
    elseif s:lang =~ &quot;Czech&quot;
      let s:ext = &quot;.cs&quot;
    elseif s:lang =~ &quot;Dutch&quot;
      let s:ext = &quot;.nl&quot;
    elseif s:lang =~ &quot;Bulgarian&quot;
      let s:ext = &quot;.bg&quot;
    else
      let s:ext = &quot;.&quot; . strpart(s:lang, 0, 2)
    endif
  endif
endif

&quot; Somehow &quot;.ge&quot; (Germany) is sometimes used for &quot;.de&quot; (Deutsch).
if s:ext =~? '\.ge'
  let s:ext = &quot;.de&quot;
endif

if s:ext =~? '\.en'
  let s:ext = &quot;&quot;
endif

&quot; The japanese tutor is available in two encodings, guess which one to use
&quot; The &quot;sjis&quot; one is actually &quot;cp932&quot;, it doesn't matter for this text.
if s:ext =~? '\.ja'
  if &amp;enc =~ &quot;euc&quot;
    let s:ext = &quot;.ja.euc&quot;
  elseif &amp;enc != &quot;utf-8&quot;
    let s:ext = &quot;.ja.sjis&quot;
  endif
endif

&quot; The korean tutor is available in two encodings, guess which one to use
if s:ext =~? '\.ko'
  if &amp;enc != &quot;utf-8&quot;
    let s:ext = &quot;.ko.euc&quot;
  endif
endif

&quot; The Chinese tutor is available in three encodings, guess which one to use
&quot; This segment is from the above lines and modified by
&quot; Mendel L Chan &lt;beos@turbolinux.com.cn&gt; for Chinese vim tutorial
&quot; When 'encoding' is utf-8, choose between China (simplified) and Taiwan
&quot; (traditional) based on the language, suggested by Alick Zhao.
if s:ext =~? '\.zh'
  if &amp;enc =~ 'big5\|cp950'
    let s:ext = &quot;.zh.big5&quot;
  elseif &amp;enc != 'utf-8'
    let s:ext = &quot;.zh.euc&quot;
  elseif s:ext =~? 'zh_tw' || (exists(&quot;s:lang&quot;) &amp;&amp; s:lang =~? 'zh_tw')
    let s:ext = &quot;.zh_tw&quot;
  else
    let s:ext = &quot;.zh_cn&quot;
  endif
endif

&quot; The Polish tutor is available in two encodings, guess which one to use.
if s:ext =~? '\.pl'
  if &amp;enc =~ 1250
    let s:ext = &quot;.pl.cp1250&quot;
  endif
endif

&quot; The Turkish tutor is available in two encodings, guess which one to use
if s:ext =~? '\.tr'
  if &amp;enc == &quot;iso-8859-9&quot;
    let s:ext = &quot;.tr.iso9&quot;
  endif
endif

&quot; The Greek tutor is available in three encodings, guess what to use.
&quot; We used &quot;.gr&quot; (Greece) instead of &quot;.el&quot; (Greek); accept both.
if s:ext =~? '\.gr\|\.el'
  if &amp;enc == &quot;iso-8859-7&quot;
    let s:ext = &quot;.el&quot;
  elseif &amp;enc == &quot;utf-8&quot;
    let s:ext = &quot;.el.utf-8&quot;
  elseif &amp;enc =~ 737
    let s:ext = &quot;.el.cp737&quot;
  endif
endif

&quot; The Slovak tutor is available in three encodings, guess which one to use
if s:ext =~? '\.sk'
  if &amp;enc =~ 1250
    let s:ext = &quot;.sk.cp1250&quot;
  endif
endif

&quot; The Slovak tutor is available in two encodings, guess which one to use
&quot; Note that the utf-8 version is the original, the cp1250 version is created
&quot; from it.
if s:ext =~? '\.sr'
  if &amp;enc =~ 1250
    let s:ext = &quot;.sr.cp1250&quot;
  endif
endif

&quot; The Czech tutor is available in three encodings, guess which one to use

  if &amp;enc =~ 1250
    let s:ext = &quot;.cs.cp1250&quot;
  endif
endif

&quot; The Russian tutor is available in three encodings, guess which one to use.
if s:ext =~? '\.ru'
  if &amp;enc =~ '1251'
    let s:ext = '.ru.cp1251'
  elseif &amp;enc =~ 'koi8'
    let s:ext = '.ru'
  endif
endif

&quot; The Hungarian tutor is available in three encodings, guess which one to use.
if s:ext =~? '\.hu'
  if &amp;enc =~ 1250
    let s:ext = &quot;.hu.cp1250&quot;
  elseif &amp;enc =~ 'iso-8859-2'
    let s:ext = '.hu'
  endif
endif

&quot; The Croatian tutor is available in three encodings, guess which one to use.
if s:ext =~? '\.hr'
  if &amp;enc =~ 1250
    let s:ext = &quot;.hr.cp1250&quot;
  elseif &amp;enc =~ 'iso-8859-2'
    let s:ext = '.hr'
  endif
endif

&quot; Esperanto is only available in utf-8

endif
&quot; Vietnamese is only available in utf-8
if s:ext =~? '\.vi'
  let s:ext = &quot;.vi.utf-8&quot;
endif

&quot; If 'encoding' is utf-8 s:ext must end in utf-8.
if &amp;enc == 'utf-8' &amp;&amp; s:ext !~ '\.utf-8'
  let s:ext .= '.utf-8'
endif

&quot; 2. Build the name of the file:
let s:tutorfile = &quot;/tutor/tutor&quot;
let s:tutorxx = $VIMRUNTIME . s:tutorfile . s:ext

&quot; 3. Finding the file:
if filereadable(s:tutorxx)
  let $TUTOR = s:tutorxx
else
  let $TUTOR = $VIMRUNTIME . s:tutorfile
  echo &quot;The file &quot; . s:tutorxx . &quot; does not exist.\n&quot;
  echo &quot;Copying English version: &quot; . $TUTOR
  4sleep
endif

&quot; 4. Making the copy and exiting Vim:
e $TUTOR
wq! $TUTORCOPY
