how can i define my own quantifier? like, let's say i want to use C as a quantifier, so I can write $C_{n = 0}^{k}$ and get $n = 0$ typeset below $C$, and $k$ typeset above $C$
@Canageek just a small collection: imagemagick (image files from and to pdf), pdfjam (a shell script to the LaTeX package pdfpages), pdfjoin (a wrapper around pdfjam), qpdf (PDF to PDF conversions, I use it frequently to remove passphrases) maybe pandoc (don't know its features, but there are some questions concerning it on TeX.SX). I think one can also shell script libreoffice but I'm not sure what is possible with it.
@DavidCarlisle Yet another reminder for myself to gather up all my information about wrong uses of \text and make a question+answer listing all these. I think nowadays, wrong use of \text is almost seen more often than users using \\ or \newline in the text.
@JosephWright I'm fighting with l3build and trying to get the tds layout for lualibs right. I have a number of lua files in the main dir. Almost all of them should be installed in texmf/tex/luatex, two in texmf/source and build.lua which is also in the main dir should not be installed.
@JosephWright I'm not quite sure if they (like the makefiles) really belong to ctan. But in the current package they are there, and so I was trying to keep this.
@JosephWright ctan.org/tex-archive/macros/luatex/generic/luaotfload. The mkXXX-files are lua-scripts. In texlive they ended in the scripts-folder. Thinking about it, I should simply not sent them to ctan. It doesn't make sense.
Using \string# (this is within double quotes as there are also spaces in the file name) produces the correct result but only after several error messages.
@JosephWright \includegraphics{"<file name with path containing spaces and #>"}. Wondering what the trick to use #` in a file name is. Using "\string#" produces the correct result, but only after errors that I have to skip over.
@JosephWright wouldn't an \edef\temp{\noexpand\includegraphics{\detokenize{"foo#"}}\temp be better (active " due to babel could lead to problems and the \detokenize would solve any number of questionable characters)?

This is a document.
It uses a nonzero parskip.
Better not doing it.

I can't compile the answer given here:
In LuaTex is it possible to change font/language according to the script/glyphs used?
Is it because it's old? My compiler says that \luatexdirectlua is undefined.
PS. With \directlua the error is:
! LuaTeX error luatexinterchartoks.lua:1: unexpected symb...
@ahorn it's not that you should change it yourself but just saying some code "causes problems" without saying what the problem is or what code you are using makes it hard to help
@ahorn it is better to use \usepackage{newtxtext,newtxmath} especially if you have any math
@ahorn there are hundreds of answers about that on site, look for longtable package (or supertab or tabu, but longtable is most common, and part of the core latex release)
@ahorn Maybe you want to have a look at tex.stackexchange.com/q/283701/121799 . Of course, you could read the ticks from the table and then build up a simple list in which you only take every 4th element, or employ one of the more sophisticated and powerful answers of that question.
@ahorn Of course you can change your input like this. The question is whether this will lead to your desired output. I'd like to argue that it would be simpler to check if the \tick is divisible by 4 and only print it then.
@ahorn just try `xticklabel={% \pgfmathsetmacro{\mytest}{ifthenelse(\tick/4-int(\tick/4)==0,1,0)} \ifnum\mytest=1 \tick \fi},` and if this does not work, which is quite possible because I do not have a full example, ask a question on the main site.
@ahorn I can reproduce your problem doing \abstract{Text of the abstract} which is wrong. You should use \begin{abstract} and \end{abstract} around the abstract text.
\documentclass{article}
\usepackage{parskip,pgfplots, needspace, times, hyperref, url, }
\begin{document}
\begin{abstract}
This is an abstract
\end{abstract}
This is a document.
It uses a nonzero parskip.
Better not doing it.
