Iso or not iso source ?

[jmburnod]

Hi All,
I am cooking a way to know on which platform a text file was created.
This script seems work but I guess someone have a better solution.

Code: Select all

on mouseUp
   answer file "Open"
   if it = empty then exit mouseUp
   put url("file:" & it) into tText
   put mactoIso(numtochar(142)) into tSearchFrench
   put mactoIso(numtochar(138)) into tSearchGerman
   if matchText(tText,tSearchFrench) or matchText(tText,tSearchGerman) then
      put "Iso" into tSource
   else
      put "Mac" into tSource
   end if
   answer "This file was created on" && tSource
end mouseUp

Thank for comment
Jean-Marc

Hi Jean-Marc,

on the mac you could use a shell command!
file -I <path_to_file.txt>

Gives me this for a ISO encoded text file:
/Users/klaus/Desktop/videos_alexa.txt: text/plain; charset=iso-8859-1

Hope this helps!


Best

I wonder if it would be reliable to just check the line endings.

numToChar(13) = Mac
numToChar(10) & numToChar(13) = Windows (LFCR)
numToChar(10) = Linux

But I'm not sure that would be consistent. If you are always on a Mac I think Klaus' shell command is reliable.

Hi,
@Klaus

I never used shell commands and i'm confused about syntax

LC Dictionary only talks about function shell.

@ Jacque

If you are always on a Mac I think Klaus' shell command is reliable.

I need it for OSX,windows and Linux to allow files exchange between all platforms
( except from mac to androïd and IOS to windows)

numToChar(13) = Mac
numToChar(10) & numToChar(13) = Windows (LFCR)

There is two chars for the line ending on windows ?

Thanks for your lights

Yes.

But oops, I got it backwards. Windows line endings are CRLF.

Yes.

Not always.
I'm using Notepad++ as a text editor on Windows and have it setup to save line endings as LF.
This is fairly common if anyone is using a programmers editor.

Wondered about that. I wasn't sure how predictable the line endings would be. On my Mac I have BBEdit set to use Linux line endings, so I don't follow the norm either. So probably a shell command is a better deal if there is one available on each platform.

Hi All

Sorry I dont know using Shell
I maybe have found a way working as Jacques has suggested
(All concerned files are created by my app)

Code: Select all

function getFileCreatePlatform pFile
   put url ("binfile:" & pFile) into x
   put "n/a" into LsepLine
   put 0 into LBOMlength
   if offset(numToChar(13)&numToChar(10),x) > 0 then
      put "win" into LsepLine
   else if offset(numToChar(10),x) > 0 then
      put "unix" into LsepLine
   else if offset(numToChar(13),x) > 0 then
      put "mac" into LsepLine
   end if
   return LsepLine
end getFileCreatePlatform

Kind regards
Jean-Marc
