bash completion file for lyx

[sven@…]

Hi,
Cengiz Gunay contributed a bash completion file for lyx. We'll include it in the
next Debian package but it's something of general interest for Linux/Unix users
so that it would make sense to place it somewhere in the LyX tarball.

bash completion file for lyx

[lasgouttes]

Or maybe on the wiki?

[sven@…]

From a packagers point of view I'd prefer to see it in the upstream tarball in
some kind of contrib folder. Actually LyX has currently no contrib folder for
such stuff and I've to admit that the use for the bash completion is only
limited to a relatively small part of the LyX userbase.

[ps@…]

it can be put into development/tools. i would be in favour of this but the
permission of the authors is needed (or rewrite needed).

[sven@…]

Beside that fact that it's more or less a shell script I considered it to be a
configuration file. Looking around in the other completion files I can find some
of them state a licence some of them don't oh and some are a bit more complex. ;)

I'll write a mail to try to make it absolutely clear that it's free and
distributable.

Ok got a response from Julien who wrote the original file for inkscape:

So you can distribute it along with LyX.

[Richard Heck]

Can we go ahead and add this somewhere?

And by the way, what am I, the lowly user, to do with this file?

[ps@…]

there are two authors and we didn't get response from the second one.
imho writing our own script would demand less energy then all this licensing
stuff :)

[sven@…]

Well it's at least derived from something within Debian, though that doesn't
give it an explizit license, I don't think there will be any problems. Beside
that I fail to see the creational high of those nowdays common helper scripts
for the bash completion but IANAL.

Richard: You maybe find an /etc/bash_completion.d/ directory on your system. If
yes simply copy the file there, restart your shell and you should be done.
If you don't have such a directory or cannot write to it simply source the file
from your .bashrc. Oh and you need some 3.x version of bash IIRC.

lets put it into 2.0 then.
i know nothing about completion stuff. is there some standard location for installing purposes or putting it into tarball is enough?

Hello, responding to your call Sanda, yes, I am still around.

As Sven mentioned in his last post above, the right place for it is under /etc/bash_completion.d/. It would be a good start to include it in the tarball, but modifying "make install" to put it in the right place would be even better. The Debian package maintainer may be some help here, too.

Having seen all the fuss about licensing for the first time, I really think it's not necessary for such a simple script. It basically follows the bash manual.

[ps]

As Sven mentioned in his last post above, the right place for it is under /etc/bash_completion.d/

i see. here (gentoo) the completion files at /usr/share/bash-completion so apparently every distro has its own ways. i'll put it into tarball only.

yes, anyway your nod here was better ;)

[ps]

r34001. from alpha2 it will be in scripts/ dir.

i dont use completion myself, but it may be possible to improve the script that it knows
possible exports (in 2.0 it would be pdf,pdf1,..,pdf4, ps, xhtml) and dbg levels is also fixed set.

Fedora seems to use the files and setup from Debian while RHEL 5 doesn't even ship with the basic bash-completion package.
Someone from the BSD world around? Oh wait they usually won't use bash. ;)

Anyway I'm perfectly fine with having it in the tarball. :)
Thanks Pavel

from release-notes to 2.0:

There is a new option

"--batch" that causes LyX to run the given commands without opening a GUI
window. Thus, something like:

lyx --batch -x "buffer-print printer default dvips" myfile.lyx

[Sven Hoexter]

Looks like that's missing in the manpage aswell ...

[ps]

fixed in r34004

[Sven Hoexter]

So something like this should do the magic for the completion.

BTW: Am I the only who thinks that the options are inconsistent?
Looks like lyx traditionally had some prefixed the unix way with only one dash and later on added longopts with double dashes and a one dash short. Now batch has a double dash without a short -b.

i was pondering about the same thing.

I'm sorry guys. Going back, I saw Sven's email from '08. I must have been confused for the request for permission, since I was the one sent the file to you for inclusion. Sorry for not answering on time.

[ps]

two ways:
either start using two dashes or change it for "-batch".
i prefer the second one because of not breaking already existing usage.

sorry for nagging but now you forgot the manpage ...

:) thanks, fixed now.

btw Sven you might know how to properly fix #2820?

Patch for completing file names for --export and -e options.

Replying to sanda:

I attached a patch for export possibilities. I wasn't sure what you came up with the --batch vs. -batch, so it is not included in the patch. also forgot to add the debug levels, but you could easily follow what I did to add that, too.

[ps]

I attached a patch for export possibilities.

the patch is in, thanks.

:) Small world! Yes, I was the Computational Neuroscience meeting. What's your full name? Send me an email if you will, so we don't go off topic cluttering the ticket.

[Cengiz Günay]

Patch to r34001 for adding comma-separated options to -dbg and added missing option -batch

[Cengiz Günay]

Please test my new patch for the -dbg options!

I also added the -batch option because it's not the only inconsistent option: -help and -userdir also fall in the same category. So IMO, until they are changed, it would be fine to keep -batch as well.

I removed the reference to the inkscape completion file because I now heavily modified the code and added a lot of new stuff. I added a "copyleft" statement assuming that will prevent the licensing problems. Please advise if that's not the case.

Cheers.

Thanks, its in r34067.

2.0.0 is ready.
