Thanks for example.

Thanks for Lionel Rault and Anton Sviridov.

Re: [twsocket] (TFtpClient) Parsing list. Help, help.

[Anton Sviridov]

Hello!
Here's routine from TurboPower iPRO component pack which I improved a bit

{ Set properties from Unix style line of directory listing }
procedure TIpFtpFileInfo.UnixStyleParse(Info : TStringList);
var
  S, A : string;
  i, idx : Integer;
  wYear, wMonth, wDay, wHour, wMin, shit: Word;
  fs: TFormatSettings;
begin
  // Get defaults for file creation date/time
  DecodeDate(GetTimeFn, wYear, wMonth, wDay);
  DecodeTime(GetTimeFn, wHour, wMin, shit, shit);

  {File Type}
  S := Info[0];
  case UpCase(S[1]) of
'-' : FFileType := ftFile;
'D' : FFileType := ftDir;
//'L' : FFileType := ftLink;
'L' : FFileType := ftDir;
  else
FFileType := ftUnknown;
  end;

  {Owner Permissions}
  FPermissions.Owner := [];
  A := UpperCase(Copy(S, 2, 3));
  if CharPos('R', A) > 0 then  {!!.02}
FPermissions.Owner := FPermissions.Owner + [faRead];
  if CharPos('W', A) > 0 then  {!!.02}
FPermissions.Owner := FPermissions.Owner + [faWrite];
  if CharPos('X', A) > 0 then  {!!.02}
FPermissions.Owner := FPermissions.Owner + [faExecute];

  {Group Permissions}
  FPermissions.Group := [];
  A := UpperCase(Copy(S, 5, 3));
  if CharPos('R', A) > 0 then  {!!.02}
FPermissions.Group := FPermissions.Group + [faRead];
  if CharPos('W', A) > 0 then  {!!.02}
FPermissions.Group := FPermissions.Group + [faWrite];
  if CharPos('X', A) > 0 then  {!!.02}
FPermissions.Group := FPermissions.Group + [faExecute];

  {Other Permissions}
  FPermissions.Other := [];
  A := UpperCase(Copy(S, 8, 3));   {!!.02}
  if CharPos('R', A) > 0 then
FPermissions.Other := FPermissions.Other + [faRead];
  if CharPos('W', A) > 0 then  {!!.02}
FPermissions.Other := FPermissions.Other + [faWrite];
  if CharPos('X', A) > 0 then  {!!.02}
FPermissions.Other := FPermissions.Other + [faExecute];

  {Search index of date property - to avoid owner/group bad data}
  // Date field always starts with 3-letter month name
  GetLocaleFormatSettings(LANG_ENGLISH, fs);
  idx:=0;
  for i := 1 to Info.Count-1 do
if AnsiIndexStr(Info[i],fs.ShortMonthNames)<>-1 then
  begin idx:=i; Break; end;
  if idx=0 then Exit;

  // Get other fields relative to Date
  {Owner}
  if (idx-3 > 0) then
FOwner := Info[idx-3];

  {Group}
  if (idx-2 > 0) then
FGroup := Info[idx-2];

  {Size}
  if (idx-1 > 0) then
FSize := StrToIntDef(Info[idx-1], 0);

  {Time stamp}
  if (idx <= Info.Count + 2) then
  // parse timestamp. got it from Indy :)
  // format: "Feb 27 19:07" or "Sep 20 2001", that is,   |
  begin
FTimeStamp := Info[idx] + ' ' + Info[idx+1] + ' ' + Info[idx+2];
i:=AnsiIndexStr(Info[idx],fs.ShortMonthNames);
if i>=0 then wMonth := i+1;
wDay := StrToIntDef(Info[idx+1], wDay);
i:=Pos(':', Info[idx+2]);
if i = 0 then // Not time info, scan year
begin
  wYear := StrToIntDef(Info[idx+2], wYear);
  wHour := 0;
  wMin := 0;
end
else
begin // Time info, correct year, scan hour, min
  if MonthOf(GetTimeFn) < wMonth then
Dec(wYear);
  wHour:= StrToIntDef(Copy(Info[idx+2],1,i-1),0);
  wMin := StrToIntDef(Copy(Info[idx+2],i+1,Length(Info[idx+2])),0);
end;
FDateCreated := EncodeDate(wYear, wMonth, wDay) + EncodeTime(wHour, wMin, 
0, 0);
  end;

  {File name}
  FFileName := '';
  for i := idx+3 to Info.Count-1 do begin
if(Info[i] = '->')then
  break;
if (FFileName <> '') then
  FFileName := FFileName + ' ';
FFilename := FFileName + Info[i];
  end;

  {Symbolic Link}
  FLinkPath := '';
  if (FFileType = ftLink) then begin
for i := 0 to Pred(Info.Count) do
  if (Info[i] = '->') then
break;
if (i <= (Info.Count - 2)) then
  FLinkPath := Info[i + 1];
  end;
end;

Moreover, I created more powerful & robust ICS FTP client descendant with Unix, 
VMS, DOS listing parsing. Let me know if someone's interested.

And it is well. I will show the result.
-rwx-- 1 user group 311521 May 29 07:33 1.jpg
-rwx-- 1 user group 311521 May 29 07:38 2.jpg
drwx-- 1 user group  0 Jun 03 16:13 test1

I can not read the date of file ' May 29 07:33'
should be '2010-05-29 07:33:00' how do this???


use FTPLISTEINFO below
liglisteFTP represent one line like  '-rwx-- 1 user group 311521
