@egreg are you around? Hi

egreg

@OFFSHARING I am.

OFFSHARING

@egreg I have a little problem with writing stuff at a certain chapter within a specific section.

egreg

@OFFSHARING I saw, but I couldn't understand what you're aiming at.

OFFSHARING

@egreg I mean after you finish the table of contents, and run the file, when you go down the pages you see the name of chapters and sections, right?

egreg

@OFFSHARING Yes, so?

OFFSHARING

12:21 AM

@egreg That is you see the table of contents, and then after that you see all chapters and sections that are found on the table of contents.

The question is how I start writing stuff at a certain chapter and a specific section?

egreg

@OFFSHARING Sorry, but I can't follow.

OFFSHARING

@egreg Suppose you finished the table of contents. How you begin writing the document itself starting with chapter I say?

Or the table of contents must be put on a different file?

David Carlisle

12:37 AM

@OFFSHARING latex will generate the table of contents for you, just put \tableofcontents where you want it to appear

OFFSHARING

@DavidCarlisle Yes, but how I start writing after that the content? Say I have this example

Tables

1. Chapter X problems

2. Chapter Y problems

3. Chapter Z problems

Now I'am done with the table of contents.

Then I wanna write the first X problem in Chapter X problems. That is to write the whole document.

David Carlisle

@OFFSHARING so you want

\tableofcontents
\chapter{X problems}
stuff here
\chapter{Y problems}
more stuff

OFFSHARING

@DavidCarlisle Oh, I need to add it there?

Let me check pls!

David Carlisle

@OFFSHARING don't even think about the table of contents until you have finished, latex will just make it based on your document sections

OFFSHARING

@DavidCarlisle It was so simple and I feel so dumb now! :-(

David Carlisle

12:43 AM

@OFFSHARING things always seem easier when you know how to do them:-)

OFFSHARING

@DavidCarlisle Thank you very very much!

@egreg It's my fault I don't know such elementary things. Perhaps you didn't even imagine this might be a problem to me.

@DavidCarlisle In all this time I thought it should be put elsewhere.

David Carlisle

@OFFSHARING you could read a tutorial such as lshort texdoc lshort has a table of contents example on page 8

OFFSHARING

@DavidCarlisle Thank you.

Hello @egreg

Joseph Wright

@DavidCarlisle I'm wondering if I should combine all (most?) of the Unicode loaders in to one file. I see Chris's point about separate ideas but I'm not sure anyone will use them like that: probably all or nothing.

Danu

I've got a puzzling little issue.

Joseph Wright

@Danu Fire away

Danu

I received an answer to my recent tex.se question, but got some errors when I tried to implement the answer in my document.

Joseph Wright

@Danu Link?

Danu

9:37 AM

To test what was going on, I compiled just the solution with my preamble, cutting out the rest of the document.

1

A: How can I specify a different style for (a difficult to describe concretely) part of a line?

Specifically for the arrows, you can use the decorations.markings library with, if desired, arrows.meta for enhanced tip options. These can be added as single markings or in stepwise fashion. You can measure in absolute units (e.g. 5mm) or as a fraction of path length (e.g. 0.5) and from the sta...

That compiled just fine (?!)

Sorry, I'm talking about the answer that does not just implement the arrowheads, but also the colored segment.

Joseph Wright

@Danu Yes, works for me

Danu

The error I get when compiling in my larger document is in a part that is seemingly unrelated. However, if I remove the solution to my question the document compiles just fine.

What could possibly be going wrong? I'm embedding the solution into a "larger" tikzpicture but that picture compiles just fine, separately.

Okay, I've made some progress: Eliminating the part where the supposed error occurs also cures my problem.

Could it really be that I've made some error in part of my code which doesn't give any problems when compiling as long as I don't insert a certain piece of code into my tikzpicture, but then suddenly gives problems?!

The error I'm getting is in a list that occurs later on: The error message is "Lonely \item---perhaps a missing list environment" (this is not the case)

The compiled pdf does indeed have problems with the list

Is it possible that list environments + certain tikz things somehow interfere with each other's workings?

Ohhhh... there is something involving "list" in the solution!!!

Boom, fixed

David Carlisle

9:55 AM

@JosephWright I should think having it all in one file and setting up all the defaults in one file is file, especially of more or less same loader code could then be used by packages to re-input unicodedata.txt to pick up new settings if needed

Danu

Replacing the occurrences of \list by \somerandomword fixed it.

I assume itemize, enumerate etc. use the \list command somehow.

David Carlisle

@Danu itemize, enumerate, center, verbatim, quote, .... all use \list

Danu

@DavidCarlisle ...so it's very bad practice to use the command \list as an auxiliary variable in tikzpicture!

David Carlisle

@Danu there is a reason that latex uses \newcommand that warns the user if they are about to break the system, rather than \def which silently does whatever it's asked:-)

@Danu "very bad" is a mild description, yes:-)

Danu

@DavidCarlisle I wish I understood more of the inner workings of latex...

@DavidCarlisle I'm pretty proud that I somehow managed to figure this out :P

Joseph Wright

10:07 AM

@DavidCarlisle Indeed: I'll adjust (again)

David Carlisle

@JosephWright fighting with github again (moving MathML spec there....) CVS is so much simpler:-)

Thanks again, amazing people of TeX - LaTeX.

David Carlisle

@Danu oh so you got an answer last night?

Danu

@DavidCarlisle Not a really satisfactory one, but it'll do for now.

The answer only works for "simple" segments of the curve (i.e. ones not including the sharp bends).

David Carlisle

@Danu that describes typical state of latex development:-)

Danu

10:17 AM

I'm still hoping for a better answer, but we'll see.

Faheem Mitha

Are there other people here having problems with excessive browser memory consumption?

This isn't new. It's been going on for awhile.

Danu

Sometimes I think I do, yes.

yo'

@FaheemMitha This happens from time to time.

Faheem Mitha

@yo' Time to time? It's a chronic thing here.

yo'

@FaheemMitha that sucks.

Now, I gotta go, Numeration Systems class is waiting...

Faheem Mitha

10:27 AM

@yo' Indeed it does.

egreg

@EllaJay Good morning!

Ella Jay

@egreg please let me know when you are back :) thanks

oh - timing!

goodmorning

egreg

@EllaJay Can you make that JPG available?

Ella Jay

@egreg sure. on it

@egreg dropbox.com/s/4xoefxn2alj49fw/XSlice1.jpg?dl=0

egreg

@EllaJay I tried, but the JPG is included correctly. This is what I get from identify: XSlice1.jpg JPEG 773x786 773x786+0+0 8-bit sRGB 131KB 0.000u 0:00.000

Ella Jay

10:48 AM

@egreg That is strange - I see it properly

David Carlisle

@egreg is it possible that lyx is using latex not pdflatex (which would make that error)

egreg

@DavidCarlisle It would say "No Bounding Box".

@EllaJay In my test, pdflatex includes the JPG. Does it in your case? Or what are we discussing about?

David Carlisle

@egreg oh yes, I wrote that code:-)

Ella Jay

@egreg ok yesterday it didn't work (errors I told you) now it seems to work. But I get some different errors. Will just work on them and brb

Joseph Wright

@DavidCarlisle Yes, that is true (certainly for projects with a linear history)

Ella Jay

11:06 AM

@egreg seems to be working! either you did some tele-magic or lyx is testing my patience ^_^

@egreg

egreg

@EllaJay :)

Ella Jay

@egreg thank you in ny case! i will likely be back!

Q: Latex file saved as .pdf instead of.tex format accidentally

I have saved my .tex file as .pdf accidentally and I cannot open now this odf file. How can I recover it? Thanks.

pdf

egreg

3:17 PM

@ChristianHupfer Silly. ;-)

Joseph Wright

5:02 PM

@DavidCarlisle I stumbled across Blocks.txt, which is a handy reference for the different Unicode blocks (surprising!). However, while it's used by ucharclasses I don't think it's ideal for the basic set up: there's no differentiation on character meaning within a class.

@DavidCarlisle (Indeed, one can see that really a wrapper is needed around \XeTeXcharclass to allow for the fact that different 'views' of code points need different divisions)

Faheem Mitha

5:14 PM

If I want to move a few lines a few characters to the right, what's a good way to do it?

Never mind, I think it's been asked already...

David Carlisle

@JosephWright yes I use blocks.txt as an input into unicode.xml it's a pretty course categorisation though.

@JosephWright but could be like the catcodetable stack handling where we left the code in the format as pretty basic and put a higher level interface to swapping it in and out into a package...

@JosephWright almost working... w3c.github.io/mathml

Joseph Wright

6:33 PM

@DavidCarlisle Indeed

@DavidCarlisle Question really is whether the current data is useful: I think from Qing Lee's comment it's certainly handy for the CJK package authors (though in an L3 context I'm minded to say we'll over-write it entirely)

Danu

7:58 PM

@DavidCarlisle An amazing amount of attention for my question: I got four answers!

Finally managed to get it right how I wanted.

in The h Bar, 1 min ago, by Danu

@UlrikeFischer's curveto decoration proved to be the key.

David Carlisle

8:36 PM

@Danu I think she may have used TeX before.

Stefan Kottwitz

9:13 PM

@JosephWright I wrote the community manager that our site user's want to have hats and sent the link to the meta post

Danu

9:24 PM

@DavidCarlisle Oh, really? ;)

Joseph Wright

10:34 PM

@StefanKottwitz Saw that: thanks

Stefan Kottwitz

@JosephWright No problem! I can write a blog post about great hat events :-)

@egreg Greetings from Venezia! I'm the 3rd week here now. Very foggy here today.

egreg

@StefanKottwitz Yes, here too! Are you going home on Saturday?

Stefan Kottwitz

@egreg I planned to fly home Thursday let evening

egreg

@StefanKottwitz Will you get back?

Stefan Kottwitz

@egreg Yes, I will return for sure! Next week I don't know (as I did my job already well) but next year I'll be in Venezia again from time to time, until April

egreg

10:54 PM

@StefanKottwitz Good!

Stefan Kottwitz

@egreg Steampunk here. In the midst of thousands of tons of pure metal, cutting, welding, in claustrophobic corridors full of wires lines for energy, light, welding, I build a redundant 10G fiber and WiFi network.

egreg

@StefanKottwitz Nice job indeed!

Stefan Kottwitz

Hotel in Venezia, work in port of Maghera

@egreg I use TeX for documentation, TikZ drawings, time enough during the weekly flights

egreg

@StefanKottwitz It's still called Marghera, as far as I know. ;-) I believe you find Venice a little nicer than Marghera.

Stefan Kottwitz

ah ja, Marghera, I just know that industrial area

but we live in Mestre

egreg

11:00 PM

@StefanKottwitz Well, Mestre is not as bad as Marghera, but, still…

Stefan Kottwitz

@egreg yes :-) I was often in Venezia, so I know

egreg

@StefanKottwitz Just like a dinner at “Chez Maxim” or at a “fish and chips”.

Stefan Kottwitz

Currently, I'm living at Piazza Ferretto,

formerly, well, classic Venice

at midnight my girlfriend wanted to take a gondola back to our ship, as she was a bit drunk :-)

egreg

@StefanKottwitz Well, some decades ago it would have been the only way. ;-) I seem to remember there's a description of a long gondola trip in “Der Tod in Venedig”.
