Re: How to get the line break char?

[Jerry Jensen via use-livecode]

Tiemo,
Is the task to compare two CSV files regardless of their line endings? If you 
don’t care what the line endings are, as Brian points out, using “file:” to 
read them will convert all line endings to just LF. Then there is no problem 
comparing, right?

One other consideration is how you are opening the file. Using “file” will
end up converting to just LF. You will need to use “binfile” to examine the
line endings native in the file.

Tiemo.

I guess I do not understand.

put charToNum(the number of chars of line (lineOfInterest + 1) of yourText)
into tChar

Then tChar can be compared to the "tChar" of any other line.

Re: AW: How to get the line break char?

[Alex Tweedly via use-livecode]

put the number of chars in line 1 of tVar into temp

put char temp+1 of tVar into tLineBreakChar

(and beware of single-line data :-)

Hi.

You cannot ask for the "last" char of a line, because LC will give you the
last "non-control" char.

Say you have the below text in a field:

abc
def


So the last char of line 1 is "c". But the number of chars of that text
snippet is 7

But numToChar(char 4 of fld 1) = 10. That is a return char between the "c"
and the "d"

How to get the line break char?

[Tiemo Hollmann TB via use-livecode]

Hello,

I want to compare two CSV files and I suspect that there is a difference in
the kind of line break. With charToNum(last char of line 1 of field "foo") I
can compare the last visible char of each line, but how can I get and
analyse the line break char that is used?

Thanks

Tiemo
