[U-Boot] [PATCH] Ignore all Carriage Returns when importing an environment.

This is used for compatibility with text files which are
using CRLF instead of LF as the end of a line.

I don't think we should do this.  If you have text files with CR-LF
line endings, then please use external tools (like dos2unix) to filter
these and bring them into the appropriate format.

I would like to put as little restrictions on the content of an
environment variable as possible.  I can see valid use for strings
that contain a CR character.

Best regards,

Wolfgang Denk

I don't see any reasonable usage for carriage returns in imported 
environment variables, but I've seen many people from the windows camp 
struggling in writing small text files to set some environment variables 
(which mostly end up in the kernel cmdline). Especially because those 
CR's often will lead to obscure errors because almost nothing (in u-boot 
or linux) is able to handle them.

Anyway I don't really care, I just found it very user friendly to strip 
the carriage returns, especially for those embedded newbies which are in 
need to use some unnamed windows IDE.

So I've decided (after having that patch lying around for about a year) 
to finally post it.

Regards,

Alexander

A CR causes the output to re-start from start of line. I can
construct all kind of fancy disply by using "echo $var" - especially
so if "var" can contain control characters including CR.  It makes no
sense striiping these out.

This is a problem that is as old as DOS, and solutions for this have
been known since.  I already mentioned dos2unix.

Thanks - but it adds restrictions to doing perfectly valid things.  I
see the disadvantages significantly bigger than what we can win - keep
in mind, that dealing wqith DOS line endings is a topic that is
decades old.

Not dealing with them too. ;)

Two other solutions come to mind: Expanding the if( '\r' ) so that it 
only removes CRs if they are before LF or make \r possible in import and 
use \r in export.

I think I would accept an option (configurable) to accept \r\n line
endings when importing text input.  For output, there shall always be
\n only.

Why don't you run the file trough dos2unix or tr -d '\r' ?

Try to explain a windows user that a text file should not contain 
carriage returns and how he can achieve that.

You'll do it once, maybe twice, than you will surrender. ;)

But you're fixing the problem at a wrong place, aren't you? Besides, removing \r 
might harm some environments, don't you think?

No, there is no other layer between the user and that function.

Anyway, as already said, I don't care, just had this patch lying around
a year and I finally surrendered to post it here (in favor of those
users). But it seems I was right in not posting it. ;)

Don't get me wrong, I'm not opposed to this patch, nor I want to demotivate you 
in further submissions. I'm just trying to figure out if actually surrending to 
crappy software on one side is a good move on our side. I'd prefer to get more 
oppinions from other people actually, I don't want the guilt to fall on me :-)

In the good old days (tm) with line printers and almost endless paper

made sense.

It still makes a lot of sense in tty output.  Guess how all the

That's why I hinted the line printers in response to "crappy software".
