- " Vim tutor support file

- " This small source file is used for detecting if a translation of the
- " tutor file exist, i.e., a tutor.xx file, where xx is the language.
- " If the translation does not exist, or no extension is given,
- " it defaults to the english version.
-
- " It is invoked by the vimtutor shell script.
-
- " 1. Build the extension of the file, if any:
- let s:ext = ""
- if strlen($xx) > 1
- let s:ext = "." . $xx
- else
- let s:lang = ""
- if exists("v:lang") && v:lang != "C"
- let s:lang = v:lang
- elseif strlen($LANG) > 0 && $LANG != "C"
- let s:lang = $LANG
- endif
- if s:lang != ""
- " Remove "@euro" (ignoring case), it may be at the end
- let s:lang = substitute(s:lang, '\c@euro', '', '')
- " On MS-Windows it may be German_Germany.1252 or Polish_Poland.1250. How
- " about other languages?
- if s:lang =~ "German"
- let s:ext = ".de"
- elseif s:lang =~ "Polish"
- let s:ext = ".pl"
- else
- let s:ext = "." . strpart(s:lang, 0, 2)
- endif
- endif
- endif
-
- " The japanese tutor is available in two encodings, guess which one to use
- " The "sjis" one is actually "cp932", it doesn't matter for this text.
- if s:ext =~? '\.ja'
- if &enc =~ "euc"
- let s:ext = ".ja.euc"
- else
- let s:ext = ".ja.sjis"
- endif
- endif
-
- " The Chinese tutor is available in two encodings, guess which one to use
- " This segment is from the above lines and modified by
- " Mendel L Chan <beos@turbolinux.com.cn> for Chinese vim tutorial
- if s:ext =~? '\.zh'
- if &enc =~ 'big5\|cp950'
- let s:ext = ".zh.big5"
- else
- let s:ext = ".zh.euc"
- endif
- endif
-
- " The Polish tutor is available in two encodings, guess which one to use.
- if s:ext =~? '\.pl' && &enc =~ 1250
- let s:ext = ".pl.cp1250"
- endif
-
- " The Greek tutor is available in two encodings, guess which one to use
- if s:ext =~? '\.gr' && &enc =~ 737
- let s:ext = ".gr.cp737"
- endif
-
- " Somehow ".ge" (Germany) is sometimes used for ".de" (Deutsch).
- if s:ext =~? '\.ge'
- let s:ext = ".de"
- endif
-
- if s:ext =~? '\.en'
- let s:ext = ""
- endif
-
- " 2. Build the name of the file:
- let s:tutorfile = "/tutor/tutor"
- let s:tutorxx = $VIMRUNTIME . s:tutorfile . s:ext
-
- " 3. Finding the file:
- if filereadable(s:tutorxx)
- let $TUTOR = s:tutorxx
- else
- let $TUTOR = $VIMRUNTIME . s:tutorfile
- echo "The file " . s:tutorxx . " does not exist.\n"
- echo "Copying English version: " . $TUTOR
- 4sleep
- endif

- " 4. Making the copy and exiting Vim:
- e $TUTOR
- wq! $TUTORCOPY
