[Octave-bug-tracker] [bug #50297] csv2cell does not ignore CR in CRLF files

[Philip Nienhuis]

Follow-up Comment #1, bug #50297 (project octave):

What io package release?

On Windows, with this script:

fid = fopen ('a_CRLF.csv', 'w')
fprintf (fid, "a\r\n1\r\n");
fclose (fid)

fid = fopen ('a_CRLF.csv', 'r')
txt = fread (fid, Inf, "char=>char")'
fclose (fid)
uint16(txt)

a = csv2cell ('a_CRLF.csv')
uint16(a{1})
uint16(a{2})


I get:

>> format compact
>> fid = fopen ('a_CRLF.csv', 'w')

fid =  3
>> fprintf (fid, "a\r\n1\r\n");

>> fclose (fid)

ans = 0
>> fid = fopen ('a_CRLF.csv', 'r')

fid =  3
>> txt = fread (fid, Inf, "char=>char")'

txt = a
1

>> fclose (fid)

ans = 0
>> uint16(txt)

ans =
  97  13  10  49  13  10

>> a = csv2cell ('a_CRLF.csv')
a =
{
  [1,1] = a
  [2,1] =  1
}
>> uint16(a{1})

ans = 97
>> uint16(a{2})

ans = 1
>>


... so at least on Windows it appears to work properly.
So I suspect that cv2cell's sensitivity for EOL type could be OS-specific; or
more specific, the C++ function getline() that csv2cell invokes might be
OS-dependent.
But my C++ proficiency is below par so don't take my idea to seriously.
