@yo' and @Derpy -- An item "We're testing advertisements across the network" has now appeared on the "Featured on Meta" box on the main site. I've registered a comment regarding the disappearance of our "community ads", asking "Will they come back?" Within the first ten minutes, it has received several upvotes, so apparently other people have the same question.

Time to sleep now. I'll check again in the morning.

@moewe Congrats!

@CarLaTeX that would be very strange, I doubt it.

@DavidCarlisle Thanks, I think the same but I saw very strange rules around, so I wanted to check

#dfp-tsp {display:none !important;}

@CarLaTeX I only know examples for the opposite direction, one institute at my university enforces the usage of MS Wort for dissertations.

@Skillmon which is actually more reasonable than requiring tex.

@DavidCarlisle et tu, Brute.

@mickep if they just take pdf specifying that it is made with tex or word or whatever is not reasonable, but some places (certainly some book publishers) have edit/review cycles built around in-document review tracking facilities and to make that work it is not unreasonable to commit to a particular file format.

@DavidCarlisle I was not fully serious, and I agree, at least partly (as long as it does not happen here).

@mickep You only have to use the file format, not the software, you can edit the zipped xml in emacs, it's OK.....

@Skillmon They are mean :)

no tlig-ligatures in harfload ;-( github.com/khaledhosny/harf/issues/37

@UlrikeFischer I can hear Hans screaming at you to stop being a dinosaur and use proper Unicode dashes

@DavidCarlisle ;-), he could say that's what one gets if one use an external library like harfbuzz. Did you like the idea of "English glyphs"?

@UlrikeFischer wasn't there some discussion of those tex ligatures not working by default in stock luatex a while ago?

@UlrikeFischer 𝔶𝔢𝔰: ℑ 𝔱𝔥𝔦𝔫𝔨 𝔶𝔬𝔲 𝔰𝔥𝔬𝔲𝔩𝔡 𝔲𝔰𝔢 𝔉𝔯𝔞𝔨𝔱𝔲𝔯 𝔞𝔫𝔡 𝔰𝔱𝔬𝔭 𝔲𝔰𝔦𝔫𝔤 𝔬𝔲𝔯 𝔤𝔩𝔶𝔭𝔥𝔰

@DavidCarlisle yes, there was a bug but it has been resolved. But +tlig in luatex is implemented in the fontloader with more or less complicated code that replaces the input. But this isn't in stock harfbuzz so harfload would have to add something for it (and xelatex has to use a mapping for this too ...).

@CarLaTeX yes they are. Unfortunately it is the institute matching my interests best, so if I want to do my doctorate at this university it would be at that chair (but I have yet to decide whether I want to do that)

@DavidCarlisle looks pretty

@Skillmon of course after the keyboard mixup with y and z, you make y look like an n and I look like a J so it's not actually readable:-)

@DavidCarlisle I can read Fraktur quite well (dependent on the used Fraktur type, there are differences I have to get used to if reading a new type for the first time)

@DavidCarlisle and I really like the look of it.

@JosephWright Is what I said in this comment correct or just a bunch of lies?

@PhelypeOleinik ooh statistics

@PauloCereda Schrödinger's comment :-)

@PhelypeOleinik ooh

@Ulysses since the rules for Mandala is so strict, I decided to ping you here with something I got today.

@Raaja wow

@Raaja Oooh

@Skillmon Of course, you have to adapt yourself to their rule :(

@CarLaTeX for me that's really something to consider. I can't stand working in Word, every time I try I get aggressive with my beloved PC, and writing something huge like a dissertation in Word appears really scary to me.

Is someone really good with regular expressions around? Does anybody know a regular expression that matches all correct usages of the macros \lstinline and \mintinline, the optional arguments and optional braced arguments are killing me. For \mintinline I got one that covers everything except for an unbraced single letter language, like \mintinline c|<code>|, and unfortunately the number of matched groups must be the same across all the usages.

@Skillmon the "regular" in regular expressions means that you can not match groups

@DavidCarlisle ?

@DavidCarlisle I meant capturing groups in the regex, not TeX groups.

@DavidCarlisle and matching balanced braces is possible with recursive regexes, which unfortunately are not supported by JS, for which I need the regex.

@Skillmon but you can't match optional [] arguments or optional {} braced grouped arguments with a true regex

@DavidCarlisle regex101.com/r/Q8tmIL/1

@DavidCarlisle nested [{[]}] aren't easily possible, but lets consider that unnecessary to cover.

@Skillmon oh ok but it is of course nested cases that are impossible (in general) although any finite depth is possible, but back to the issue do you need to capture it all in one regex rather than just tokenize using regex and grab the bits in javascript code?

@Skillmon otherwise known as non-regular regular expressions:-)

@yo' @CarLaTeX I know right :) it was the best thing today ^^

@DavidCarlisle I'm aiming to integrate it into an existing framework and don't want to rewrite the entire system :(

@DavidCarlisle lol

@HaraldHanche-Olsen thanks, I know. As already said, the decision wasn't made by mean, I just have to stick with it if I don't want to rewrite an entire system.

@Skillmon just add a level of indirection: apply regex to your regex using code to make it use a more powerful grammar construct. what could go wrong?

@UlrikeFischer because all the best mathematicians are English?

@DavidCarlisle they seem to speak every language apart from latin ;-). Probably math is too new for it.

@UlrikeFischer multiplying with roman numerals is tricky

@DavidCarlisle ;-). Do we have some plan about a global lua table for l3kernel/latex? I would like to store some functions for the page resources there.

@DavidCarlisle one should perhaps load a package if one wants to see the table it uses ;-) Now I found l3kernel in _G.

@UlrikeFischer there was some discussion a while back about top level table usage, I think the outcome was that luatex and/or the font loader already used so many tables trying to constrain things to a few top level tables was a lost cause....

@DavidCarlisle I remember the discussion (I think I started it ...). But as we have a l3kernel table it makes sense to use it. It allows me to use pdf as (sub) table name without clashing with the global pdf table ;-)

@UlrikeFischer yes avoiding top level names is a good aim

@DavidCarlisle I see Peter is keeping both of us busy (I've had that query by email)

@JosephWright glad to see he's still active, but I gave up when it got to windows editor config:-)

@JosephWright have you met him or is that before your time on uktug?

@DavidCarlisle Before my time

How can I convert a number to corresponding letter of alphabet? I remember seeing something of this sort in TeXbook but can't find it now.
