Similar remarks apply, BTW, to other EPICS tools. For instance, I
noticed in the past that dbExpand silently ignores the last line of a
dbd include file if it doesn't end in a newline. This has caused
endless grief to Windows users, as editors for Windows generally don't
automatically add a newline at the end.
If this hasn't already been fixed, I propose to put it on the list of
things to be done before the next release of base. I'd say chances
that people rely on the faulty behaviour are practically zero.
I would have no problem in including a fix for that in base, I just
can't see how to modify dbStaticLib to do it myself. Patches from
Flex/Antelope experts welcomed.
IMHO they should fix windows rather than that we should break something
else to accommodate it.
Maren:
I have two questions:
(1) How exactly does 'something else' break if we fix this (which I regard
as a bug) in dbStaticLib?
(2) Do you really regard it as correct behaviour (and rather think Windows
is broken) if a tool that processes a text file silently ignores the last
line whenever it misses a trailing newline? Note that this last line is
visible in /any/ text editor or text viewer on any platform. It is merely
a /convention/ that (many, not all) Unix editors automatically add a
newline when the file is saved.
Lines should end in a newline character.
IMHO it's part of what a line is.
Saving the space that the newline character occupies may have been
an issue when disk space was expensive and people were communicating
on 1200 baud modem lines, but it shouldn't be now.
I guess this goes in the direction of 'once FITS always FITS' -
and I'm well aware of that we're not talking about FITS here and
that a lot of the people in the EPICS community don't know what
FITS is. It's always been that way, and we should keep it backwards
compatible.
I'm not saying we should necessarily keep ignoring the last line
if it misses the newline character, but we should have newline
characters on the ends of all lines.
