is there a thmtools-way of changing the \topsep of amsthm's proof env?
\addtotheorem{pre,post}headhook[proof]{\topsep=something} do not seem to do anything
(I can redefine the env, of course...)

another cute thing would be a way to automagically have a command defined by \DeclarePairedDelimiter use \big when in a displayed equation.

@JosephWright Hello :) Sorry I never catch you here. Now I'm going to Portland I'm rather, er, behind in my organisation / work to get done before I leave.

@JosephWright I didn't mention it yet but I've been playing more with the idea of dealing with auxiliary data. Catcodes are annoying :)
 
Joseph Wright
Joseph Wright
@WillRobertson Almost certainly
 
Will Robertson
Will Robertson
@JosephWright Years ago I remember reading about various TeX-based encoders that took text input and mangled it in various ways (David Carlisle would approve) — I don't think those approaches preserved catcodes, but what I was thinking was that we could store auxiliary data in a format that preserved catcodes in a "safe" way… the things Bruno has been working on help with this
 
Joseph Wright
Joseph Wright
8:09 AM
@WillRobertson You mean something like the regex approach to marking up catcode, I assume
 
Will Robertson
Will Robertson
@JosephWright Yeah, something like that. The encoding idea came from texdoc aroundthebend chapter 11. The big question is efficiency and how much data we might be expecting.
 
David Carlisle
David Carlisle
@WillRobertson one approach is to ban catcode changes.
 
Will Robertson
Will Robertson
@DavidCarlisle Yeah, just have everyone write their documents with \ExplSyntaxOn :)
@DavidCarlisle You're probably right though — if auxiliary data is only ever written with document catcodes you save this particular variety of hassle.
 
Stephan Lehmke
Stephan Lehmke
8:24 AM
@WillRobertson Honestly, I think catcodes should not be something to perpetuate. Keep syntax on the character level, allow different catcode regimes for parsing, and maybe use \scantokens.
 
Will Robertson
Will Robertson
@StephanLehmke Yes — I wouldn't want to try and preserve arbitrary catcode changes, only those between document syntax and expl3 syntax.
 
David Carlisle
David Carlisle
@WillRobertson no but just as aux file is always written assuming it will be read back when @ is a letter (even if it is not at the point the item is written) You can have one or more fixed (possibly named) catcode regimes, I don't think it's necessary to support arbitrary packages making arbitrary characters active (that may mean that all ascii punctuation will need to be active always)
 
Will Robertson
Will Robertson
@DavidCarlisle I agree, I don't think it's necessary either. The "edge" cases for me are when you might be taking user input and combining it with expl3 macros — but then I don't know why you'd want to do that anyway. Oops, gotta run.
 
Stephan Lehmke
Stephan Lehmke
@WillRobertson @JosephWright yea this is a serious issue. Maybe one could "rewrite" expl3 syntax to user level syntax?

Q: How to split a long table into pages with multicolumn in each page?

MaryamI have a very long table (64 rows) with 14 columns. I split it with lontable package, but it keeps error for multicolumn syntax. Any suggestion please? part of the table is here: And I couldn't figure out how to put "continued from the previous page" in between? \documentclass{article} \usepac...

I have a short non-TeX-related question, but I'm confident someone can answer it :) I'm currently writing my thesis and I have an appendix which is currently named "Auxillary Calculations". Now I also want to include conversion tables for units and other stuff into it such that the title "Calculations" doesn't quite fit anymore. I'm tempted to name it "Auxillary Stuff" but that sounds awful. Can anybody devise a better name?
(I won't split it up in two appendices, as both would turn out to be only two pages or so)
 
Paulo Cereda
Paulo Cereda
@HenriMenke I'm not a native, let alone a good speaker at all, but how does complementary material sound to you?
 
Henri Menke
Henri Menke
@PauloCereda That's a really nice suggestion. Although the word "Auxillary" has the advantage that it matches "Appendix A" like in the TeXbook :)

@PauloCereda I read on the “International New York Times” I got on the train an article about a football school in São Paulo, specifically for goalkeepers: opening a school for goalies “seemed about as feasible as opening a school for sunbathing in Siberia”. The school is guided by Zetti and it seems to be having success.

What tools are there to convert PDF to EPS on a Mac? I know pdftops -eps (from xpdf suite), which messes up my file. I know pdf2ps and ps2eps which also mess up my file: they recalculate my carefully constructed bounding box and rasterize some text.
What other options do I have?
I do have access to Acrobat, but again: it messes up fonts (original text gone, looks like garbage)
Bloody journal only accepts EPS, as usual ... I really don't want to rasterize everything.
 
egreg
egreg
@Szabolcs I tried converting a PDF to PS and back, fonts were preserved.
 
Szabolcs
Szabolcs
Hm, it looks like not all of these EPS are messed up. Mac Preview will convert back to PDF and that's when fonts get messed up, I think.
@egreg Usually some of these tools work for me. But sometimes they don't. It depends on the PDF input. It seems today I was particularly unlucky with this PDF. BTW do you know if there's a GhostScript based tool that will convert to EPS (not PS) and preserves the bounding box?
 
egreg
egreg
@Szabolcs Also the bounding box is preserved.
 
Szabolcs
Szabolcs
@egreg Which tool are you talking about?
 
egreg
egreg
@Szabolcs I used pdf2ps
 
Szabolcs
Szabolcs
2:26 PM
@egreg What is the syntax to produce an EPS (not PS) and preserve the bounding box? I used pdf2ps fig1.pdf which produced fig1.ps. Then I used ps2eps fig1.ps which produced fig1.eps. But now the bounding box was slightly shrunk, leaving zero space on the sides of the figure.
 
egreg
egreg
@Szabolcs What I get from pdf2ps is already EPS, with correct comments.
 
Szabolcs
Szabolcs
@egreg You are right. It is indeed an EPS, even though the extension is .ps. And the bounding box is correct.
Unfortunately it rasterizes the fonts. I'll search specifically for that problem.
 
egreg
egreg
@Szabolcs ps2eps has the bad habit of shrinking the bounding box, trimming white space. My test file had been produced with pdfcrop -margin 2, and ps2eps gobbled 2bp on each side. I don't get font rasterization, the font resources are in the PS file and, as I said, converting back to PDF shows no rasterization.

@cgnieder: nothing new so far, but there's an announcement: github.com/cereda/arara :)
 
Szabolcs
Szabolcs
2:46 PM
@egreg I'm sure it depends on the particular file and the particular fonts. It only rasterizes some of them. But finally it turned out that the EPS generated by Acrobat was good (it was just not displayed well by Mac Preview). So my problem is solved.

Q: Why lua and not python?

user2751530I mean instead of lualatex. I came across the python package, so I am not asking about python support. What was so special about lua that people spent so much time on that instead of doing something with python (and which would be arguably be more useful)?

python lua
Too broad, offtopic.
 
Szabolcs
Szabolcs
Is there something one can do when references start turning out ugly like this?
I have 7 of them that look like this with two-column revtex4.
I made the mistake of writing the paper with pdflatex + microtype but now need to switch to latex -> dvi before submission ...

@PauloCereda do you understand this comment, the very idea seems shocking to me:
Have been using this for a while now with great success. Just to mention a bug I just hit, for the archives: The \ztag command has to be placed in the last column. E.g. if you just have content in the leftmost column, you still have to do my stuff goes here && \ztag{Foo}. Otherwise, the tag is not set, and I think even equation numbers are messed up. — rainmaker 5 mins ago

@DavidCarlisle A bug? Preposterous. :)

@Brent.Longborough They really had a bad idea when they adopted the dotless i.

@egreg Really? How did we get here?
 
egreg

The dot on the i is similar to the small sign that Germans were used to draw over their lowercase u's in handwriting, to distinguish them from the n's. The dot was used for avoiding misunderstandings and has remained also in print.
 
Brent.Longborough
Brent.Longborough
@egreg Thanks. I wasn't aware of that.
 
egreg
egreg
@Brent.Longborough The Latin I had no dot, of course.
Turkish should have used i and ï
 
Brent.Longborough
Brent.Longborough
@egreg Hmm, but surely that was only because of blackletter?
 
egreg
egreg
@Brent.Longborough It started long before blackletter: fr.wikipedia.org/wiki/Point_suscrit_dans_l%27alphabet_latin
 
Brent.Longborough
Brent.Longborough
9:19 PM
@egreg Fascinating!
 
egreg
egreg
@Brent.Longborough Russians draw a small line over their т in order to distinguish it from a ш. In handwriting they bear the same relationship as "n" and "u"; the т is written as we write "m".
Just to make things easier, the handwritten п (pe) is written like our "n"; and г (ge) is written like a dotless i.
The и is written like a "u" and д is our "g"

@egreg Nooo.
@egreg It was a lecture at the university about archives in general. And you need to read Sütterlin/Kurrant to know what had been written down. Being able to wright it was an extra bonus.
