[Implemented] PrintN() should produce #CRLF$

horst · Post by **horst** » Mon Dec 03, 2007 7:12 pm

Just found out that PrintN() appends a #LF$ only, which is ok for the console window output, but may cause problems when redirectied to a file.

Notepad.exe insists that lines must be terminated with CR+LF. Other editors are a little more flexible, and I don't use Notepad either, but that's why a user of my programs had to tell me about this.

Question: Why doesn't PB add #CRLF$ instead of #LF$, since on the screen there is no difference anyhow?

Unix/Linux use LF only, Mac used to use CR only and DOS/Windows use CRLF - I guess that's what Rings meant to say

I think Rings means that CR+LF is a Windows only solution and wouldn't be considered crossplatform.

I think there should be an option to change this.

WriteStringN() creates CRLF on Windows, I guess it uses the correct line endings for the other platforms. I don't know why PrintN() should be different from that - use the line ending for the platform it is running on.

I would suppress PrintN() and WriteStringN() commands (if i was Fred).
Imo is at the hand of the programmer the eol character/s.

LF is a linux only solution and wouldn't be considered crossplatform either.

Psychophanta has a good point, being that you would just use Print(Text$+EOL$) instead of PrintN(Text$). That way you control what is written instead of the default.

I second what djes said also, there should be an option to change this.

Thank you, that's the point.

@Psychophanta, Demivec:
I think it is not very realistic to ask for suppression of PrintN() and WriteStringN().
And as long as these commands exist, they should append the platform dependent EOL code.

@djes, Demivec:
I don't think, there should be an extra option (i.e. optional parameter). You can always code Print(text$ + #whatever$).

I changed it to CRLF for windows.

LF is a linux only solution and wouldn't be considered crossplatform either.

Actually <LF> is a Linux and Unix and BSD (which therefore presumably includes OSX) - so IMO <LF> is the standard and <CRLF> (Windows) or <CR> MacOS are the non-standard exceptions.

It seems to me that Windows uses <CR> & <LF> to end a line, so while that is inefficient it should be readable all major OS's (Unix & Linux & OSX & Win)
