I'm not Apple's biggest fan right now. We're likely to get many questions per this change – read up on this El Capitan upgrade issue. Might be a worth a bookmark for the next few weeks.

Far and above the easiest fix is to tell users to upgrade to MacTeX 2015, but this doesn't mean editors are automatically updated to use the new /texbin search path.

Q: Mac OS changes that affect lots of answers

Those us who are Mac users may be aware that the next version of OS X will change major aspects of the the way users can interact with the underlying Unix infrastructure of the OS. In particular, access to /usr/ will essentially be eliminated, even with admin privileges. As a result, starting fro...

There were a few suggestions of what to do in the comments, but nothing definitive ever seems to have been decided.

@AdamLiter Ooooh, I did not :) Thanks for pointing it out – I'll give that page a read-through and try to offer some thoughts.

@DavidCarlisle It's the priority business: if I add that back in then everything works

Joseph Wright

5:15 AM

@DavidCarlisle I've fixed one issue: latexrelease wasn't getting things back on track, now it is

@DavidCarlisle We might have to simply put up with the priority business: that can get fixed today if we agree and sent (CTAN will love me)

David Carlisle

6:39 AM

@JosephWright sent you mail but then saw you'd done it already, yes agree we should do whatever to get it working today although I will try to look later I think it should be possible to emulate priority without it being in ltluatex, can always do that next time.

Joseph Wright

@DavidCarlisle OK

David Carlisle

@JosephWright yes was worrying about that last night but decided after realising I was dosing at the keyboard that I wouldn't trust any changes I made, so gave up last night:-(

David Carlisle

7:39 AM

@JosephWright so just got in, I see ctablestack just got announced...

Joseph Wright

@DavidCarlisle :-)

@DavidCarlisle Working on the ctex tests for expl3 [which also pick up the LaTeX2e issue :-)]

David Carlisle

@JosephWright I think I can see how to do priority better in the luatexbase emulation, or have you already added it to ltuatex? Also the only values ctex seems to use are 1 and 1000 it might make sense to have a version of add_to_callback which reliably adds to the other end rather than just hoping 1000 is enough, so we have something to tell people whet to do instead of using priority

Joseph Wright

@DavidCarlisle Hope my comments on the pull request are OK

@DavidCarlisle I've only fixed latexrelease

@DavidCarlisle Did my tests on what would fix the issue in my local tree, not in the sources

David Carlisle

@JosephWright was it just priority being ignored or other things as well

Joseph Wright

@DavidCarlisle Just added the priority code from original luatexbase to add_to_callback in ltluatexand adjusted new luatexbase to pass the value through

@DavidCarlisle, @PauloCereda On the issue I asked about last night: I've done a complete install of TL'15 on Ubuntu 12.10LTS and it still says the Chinese font has no Chinese chars! Must be an issue with the OS or something.

Right, next step is to set up a more recent Ubuntu I guess

David Carlisle

7:46 AM

@JosephWright so, ... do you want to do that or do it in luatexbase (it already catches the priority argument but I forgot I only used it there in the "first" case, but if priority > 1 it could iterate through the description list to unregister all callbacks then put back the ones with position less than the stated priority then the new one then the rest of the old ones

Joseph Wright

@DavidCarlisle That sounds like a better solution if it works: I really don't like the priority idea in general, so if we can keep it out of the kernel ...

David Carlisle

@JosephWright OK I'll have a go, see if it works....

Joseph Wright

@DavidCarlisle I'll still need to fix the kernel w.r.t. latexrelease but that's then a lower priority

@DavidCarlisle You're happy with that plan I guess?

David Carlisle

@JosephWright if it works:-)

David Carlisle

9:18 AM

@JosephWright it works!

Joseph Wright

@DavidCarlisle Yay!

@DavidCarlisle Still can't work out why TL on Ubuntu can't find chars in Fandol

David Carlisle

@JosephWright I need to remove debugging print statements and move it to dtx file, but I just changed this function in luatexbase.sty

function luatexbase.add_to_callback(name,fun,description,priority)
  texio.write_nl('\string\n HERE: adding ' ..
                  description ..
                  ' to ' ..
                  name ..
                  ' with priority ' ..
                  (priority or '@@@'))
    texio.write_nl('Original list')
    for k,v in pairs(luatexbase.callback_descriptions(name)) do
      texio.write_nl('    ' .. k .. ': ' .. v)
    end
  local priority= priority
  if priority==nil then
   priority=\string#luatexbase.callback_descriptions(name)+1

Joseph Wright

@DavidCarlisle Good plan

Paulo Cereda

@JosephWright Oh my, that is something complicated to track it down.

Joseph Wright

@PauloCereda I know

@PauloCereda At present I'm minded to go with a bail-out, but I really need to work out why there is an issue

@PauloCereda I'll try Fedora next

Paulo Cereda

9:35 AM

@JosephWright Got it.

@JosephWright Yay!

Joseph Wright

@PauloCereda If it's just Ubuntu that will be very weird, but you never know

Paulo Cereda

@JosephWright I can't think of any explanataion. At first I thought it would be something related to AppArmor (I guess that would be the name of the software firewall thingy) but that would be just silly.

Joseph Wright

@PauloCereda Font loader issue, but as I'm not really up on the detail of the interaction between luaotfload and OS stuff it's not so easy to track down

@PauloCereda Font itself is fine, of course

Paulo Cereda

@JosephWright hmmm perhaps font lookup?

Joseph Wright

@PauloCereda I suspect so but it's hard to be sure. First test is as I say a different Linux, stripped down as for Ubuntu, and see what happens

David Carlisle

9:41 AM

@JosephWright git push... can you give that a try...

Joseph Wright

@DavidCarlisle Works for me

David Carlisle

@JosephWright It didn't help that first I put everything back in exactly the wrong order:-)

Joseph Wright

@DavidCarlisle :-)

David Carlisle

@JosephWright I think as emulation this should be fine but we should probably think of adding a prepend_to_callback or some such that's like add_to_callback but from the other end, I can't see anyone really ever wanting to add to the middle

Joseph Wright

@DavidCarlisle I've sent to CTAN: if deals with the immediate problem

David Carlisle

9:48 AM

@JosephWright yes, I meant for 2016/01/01 or whatever

Joseph Wright

@DavidCarlisle See what gets asked for

David Carlisle

@JosephWright yes but I was thinking if we want to ease people off the luatexbase interface we may need to proactively suggest what they should change to, and as all the ctex examples have priority 1 or 1000 having a canned alternative for each of those would simplify matters

Paulo Cereda

El Capitan downloaded, time to make a bootable USB stick. :)

Joseph Wright

@DavidCarlisle Yes

@PauloCereda Good plan

Paulo Cereda

@JosephWright Have you downloaded it too?

Joseph Wright

10:00 AM

@PauloCereda No, as I've said before, I can't go beyond Mavericks as our work VPN software then breaks

Paulo Cereda

@JosephWright Ouch.

Joseph Wright

@PauloCereda support.f5.com/kb/en-us/solutions/public/15000/700/…

Paulo Cereda

@JosephWright They are now two versions behind. :)

Joseph Wright

@PauloCereda We've been told: As the VPN software is due for replacement then, hopefully in the coming months we should have further information to provide.

Paulo Cereda

@JosephWright ooh

Joseph Wright

10:12 AM

@PauloCereda I suspect that the supplier are pushing us to upgrade the entire VPN hardware

Paulo Cereda

@JosephWright Possibly. :)

@JosephWright: I use VPNC here. :)

David Carlisle

LaTeX2e <2015/10/01> patch level 1

Joseph Wright

@PauloCereda Not up to me, up to my employer

David Carlisle

So I wonder how many people ever used LaTeX2e <2015/10/01> :-)

Paulo Cereda

@JosephWright USP doesn't want "third party" softwares as well, but what they know. :)

Joseph Wright

10:16 AM

@PauloCereda I mean you need the right VPN software to connect to the VPN hardware, and that's determined by the manufacturer of the hardware

Paulo Cereda

@JosephWright boo :)

David Carlisle

I see Mico is planning on writing a very long book!

Joseph Wright

@DavidCarlisle ?

@PauloCereda Installing Fedora VM now

Good maen

David Carlisle

11:04 AM

@JosephWright luatex list (he wants \setcounter{chapter}{2^63})

So if I want w3c.github.io/xml-entities/2007doc/Overview.html to automatically rebuild on commit I need to use something called Travis CI @JosephWright know anything about that? :-)

Paulo Cereda

11:33 AM

@DavidCarlisle ooh

Joseph Wright

@DavidCarlisle :-)

Paulo Cereda

@DavidCarlisle Maybe we might need another workflow.

Joseph Wright

@DavidCarlisle Rebuilds on push not commit, but there we go

David Carlisle

@JosephWright push/commit what's the difference:-) That file has been in CVS for the last 20 years, takes a while to get the new terminology.

Paulo Cereda

@DavidCarlisle hm so you are old.

:)

David Carlisle

11:44 AM

@PauloCereda not as old as ...

Joseph Wright

@DavidCarlisle :-)

Paulo Cereda

@DavidCarlisle ooh :P

12:28 PM

Does anybody understand the question with minimizing the white space?

David Carlisle

@Johannes_B no

Ho1

Hi. Once I found a great answer on how to fix lost fonts of a PS file converted to PDF on TeX.SE. I can not find it in my web searches. How can I find that answer?

Paulo Cereda

Ho1

Nice. :-)

Johannes_B

@DavidCarlisle Got more unclear, imho.

Q: Mission control font is aliased in OSX El Capitan

I just upgraded my Mac to 10.11 and noticed the aliased font in Mission Control. I tried to include a screenshot of it, hope the issue is clear. :) The font was fine in Yosemite. Is anybody facing the very same issue? I could not find a proper setting about it in the System Preferences.

osx mission-control el-capitan

Already an issue. :)
