@DavidCarlisle Looks the same as I get: mainly the discretionary and kern logging changes
@DavidCarlisle Testing against Lua5.3 is a little more complex: we could I guess as it to the same mechanism as is used for LuaJITTeX and make it look like the same engine. However, we only need to do that if there are issues with Lua code (which might well then be tested in other ways)
@JosephWright yes I might just leave my setup as it is (with luatex53-1.07 just copied into my local texlive 2017 bin as luatex) so I'm running texlua53 to drive l3build and testing against luatex53, so it should show up any differences....
I suspect that there will be user pressure for tl to have a lualatex53 out of the box once the luatex53 binary is there
@egreg Hi, Prof. In the mathematics I website I asked a very clear and simple question. I find it really unjust that the possibility of asking a clear and simple question is blocked. Even: on hold. When I was at university, they explained only 4 lessons of combinatorics without any exercise, and I do not know many conditions, formulas and reasoning. Could you, kindly, help me?
@DavidCarlisle Probably for the sort of people who use Lua heavily, yes, though not for those just wanting system fonts, etc.
@DavidCarlisle I'm slightly surprised the TL people didn't just make the switch this year
@DavidCarlisle I get no additional failures with Lua 5.3 compared to Lua 5.2
@DavidCarlisle lua.org/versions.html doesn't suggest a lot of difference for most users (the Unicode support is basic)
@DavidCarlisle I can see things like luaotfload picking up on some of the detail (lua.org/manual/5.3/readme.html#changes), though I suspect they'll be conservative in Lua version requirements
@JosephWright yes I was just looking at the manual that got build with luatex 5.3 and there isn't much lua 5.3 stuff there really, so I suppose main difference is which external lua modules work.
@UlrikeFischer context is using luatex53 by default so presumably if there are issues porting the latest font loader from there will fix, but our (not very extensive) tests of opentype font loading seem to work
@JosephWright I think it's going to be a pain though, It's easy for Hans/Luigi to suggest dropping a luatex85 binary on texlive but unless texlive adds the symlinks/copies as lualatex53 texlua53, ... it's not really usable by people and if texlive does that, all the IDE's like texworks will need configurations to pick it up, then presumably next year it all gets removed and everything updates to lua 5.3 (or 5.4 or whatever)...
@JosephWright .. I was wondering if it would be better if texlive had a configuration option to do what I just did by hand of making luatex be luatex 53 and so all the symlinks use 5.3 under the existing names such as texlua
@DavidCarlisle yes, but I don't have the impression that there is someone who could port the latest font loader. Philipp didn't do anything for nearly a year and while one can use the context font loader directly currently it could easily happen that some future font loader is no longer compatible with the luaotfload wrapper.
@UlrikeFischer Probably longer-term we need to sort out a wrapper which works directly with the ConTeXt version: whilst Hans doesn't like the idea, the ConTeXt loader effectively is part of the engine (the idea that everyone goes off and writes their own font loader code is not realistic)
@DavidCarlisle That would be good, though I guess the issue then is getting changes made ... on the other hand, if we find issues in HarfBuzz and report them, we help a lot more people than just TeX users
@UlrikeFischer, @DavidCarlisle Probably one for email ...
Urs Freuler (born 6 November 1958 in Bilten, Canton of Glarus) is a Swiss cyclist, who raced professionally between 1980 and 1997, during which he won 124 victories. He was named Swiss Sports Personality of the Year in 1982 and 1983.
He was born in Bilten. As an amateur, he was the champion of his country in several categories and also achieved fame in international competitions.
He was a racer of great speed, who participated both in road races as well as track cycling. In the latter, he was the world champion in the keirin twice and the points race eight times and victor in 21 six-day races....
@PauloCereda I know of at least one PhD thesis whose abstract is 50% longer (not counting punctuation): “Yes.” And that was not in reference to the title, as this one was.
The International Journal of Advanced Computer Technology is a publication which has been described as a predatory open access journal – a publication which has some of the surface attributes of a benign open access journal but is actually an exploitative and deceptive corruption of that model, operating as a disreputable vanity press with little scholarly value.

In 2005, two scientists, David Mazières and Eddie Kohler, wrote a paper titled Get me off Your Fucking Mailing List and submitted it to WMSCI 2005 (the 9th World Multiconference on Systemics, Cybernetics...
@PauloCereda There's also a math paper published consisting of a single figure. Not one word, other than the author's name and perhaps some references. And the title, of course: Something like “A proof of [someone]'s conjecture”.
Here's a (possibly unicode related) question: Why do the angle brackets ‘〈’ and ‘〉’ come with such big spaces? (I did not type a space between those quotes. That space is part of the character!)
Oh, wait. I guess I found the answer: They're in the section CJK Symbols and Punctuation. I suppose the spacing is right for that context.
But (thanks to @barbarabeeton probably) we have the pair ⟨⟩ U+27E8 MATHEMATICAL LEFT ANGLE BRACKET and U+27E9 MATHEMATICAL RIGHT ANGLE BRACKET to use instead.
@DavidCarlisle Ah, this deprecation notice tells part of the story at least: “These characters are deprecated and are strongly discouraged for mathematical use because of their canonical equivalence to CJK punctuation.”
@HaraldHanche-Olsen yes, they were the html ⟨ and ⟩ entities in html prior to html5, I managed to get those entities changed to U+27e8 and U+27e9 but changing entity definitions in html is a scary business so it wasn't universally popular:-) (the normalisation to the CJK versions was essentially added by mistake but unicode stability rules meant that they would prefer to add the new mathematical versions without that normalisation than remove the normalisation once it had been added
I am already using the other answer to realize my idea, and if I am honest, I can't exactly see how this is supposed to be easier. Nevermind, thank you for your help! — n2019 mins ago
@JosephWright @WillRobertson glyph_not_found callback looks an interesting possibility if nothing else could make a real error instead of log message, but could also presumably find a glyph in some other font...

Is there any pdf reader for windows that would let me replace the mouse pointer -- often a hand ;-( -- w/ something more appropriate for full-screen presentations (like the laser pointer option in powerpoint)?
@HaraldHanche-Olsen the report I have is about miktex, so windows. They have problems when they compile in texworks a file which inputs a file (e.g. a graphic) which is in the same (network) folder. From the log it looks as if the folder is not the current folder. I would like to know if this is miktex or texworks specific.
@HaraldHanche-Olsen When everything is moved to a local folder there is no problem.
@PauloCereda About £900 if I go from Heathrow, more like £1100 if I go from Norwich (work), but I don't have to go to London to do that so it works out much the same
@PauloCereda Comes down to whether KLM are competitive for the 'main' flight: here they are, so it makes sense to go that way. For the US it's different ...
@PauloCereda I'll need to see what other team members plan, but as this is holiday days for me, likely I'll only do Thursday to Sunday (flight is at something like 2130)
@JosephWright And your colleagues won't believe you came back from Rio without a tan (in my case, as my skin is very pale, I look like a red shrimp after some sun exposure).
@JosephWright Cool, local flights are very doable.
