I'm trying to create a new environment in my LaTeX document where indentation in the next paragraph following the environment is suppressed.
I have been told (TeXbook and LaTeX source) that by setting \everypar to {\setbox0\lastbox}, the TeX typesetter will execute this at the beginning of the next paragraph and thus remove the indentation:
\everypar{\setbox0\lastbox}
So this is what I do, but to no effect (following paragraph is still indented):
\newenvironment{example}
{\begin{list}
{}
{\setlength\leftmargin{2em}}}
{\end{list}\everypar{\setbox0\lastbox}}
I have studied LaTeX's internals as well as I could manage. It seems that the \end routine says \endgroup and \par at some point, which may be the reason LaTeX ignores my \everypar setting. \global doesn't help either. I know about \noindent but want to do this automatically.
Example document fragment:
This is paragraph text. This is paragraph text, too.
\begin{example}
\item This is the first item in the list.
\item This is the second item in the list.
\end{example}
This is more paragraph text. I don't want this indented, please.
Internal routines and switches of interest seem to be \#endpetrue, \#endparenv and others. Thanks for your help.
I couldn't get anything to work without redefining \end, but I'm certainly no expert.
The following is quite hacky, but worked in my limited testing. Of course this will interfere with nested environments (you should be able to redefine \begin to restore the old \end if you have problems).
\newenvironment{example}{%
\bgroup
\let\oldend=\end
\def\end##1{\oldend{##1}\csname #afterindentfalse\endcsname
\csname #afterheading\endcsname}
\begin{list}{}
{\setlength\leftmargin{2em}}
}{%
\end{list}
\egroup
}
Can't you avoid this by not having a blank line between your environment and the next line?
This is paragraph text. This is paragraph text, too.
\begin{example}
\item This is the first item in the list.
\item This is the second item in the list.
\end{example}
% (No blank line)
This is more paragraph text. I don't want this indented, please.
Something as simple as this works for me:
\makeatletter
\newenvironment{example}{%
\bgroup
\list{}{}
}{%
\endlist
\#afterindentfalse
\#afterheading
\egroup
}
\makeatother
But, it doesn't work before the first \section (or \chapter, in the case of classes "book" and "report") is called. I don't know why.
I tried the Ivan's answer, but it wasn't working for me. But I did get it working! Here's what I did:
\makeatletter
\renewenvironment{quotation}{%
\bgroup%
\let\oldend=\end%
\def\end##1{\oldend{##1}\csname #afterindentfalse\endcsname%
\csname #afterheading\endcsname}%
\list{}{\listparindent 1.5em%
\itemindent \listparindent%
\leftmargin 1.5em% This controls the size of the indentation
\rightmargin \leftmargin
\parsep \z# \#plus\p#}% This line reduces inter-paragraph space to normal values.
\item\relax%
}{%
\endlist%%
\egroup%
}
\makeatother
The advantage to this is that it typesets your blockquotes very nicely, and removes the indentation from paragraph after the blockquote.
You can do this without redefining \end
\makeatletter
\newenvironment{example}
{\begin{list}
{}
{\setlength\leftmargin{2em}}}
{\end{list}%
\def\if#endpe{%
\#doendpe
\let\par\##par
\iffalse}}
\makeatother
Explanation
\end changes \everypar after expanding \endexample. To make things even more complicated it sets \par to restore \everypar{}. Appearently \#doendpe is ment to make sure that there is no indentation if the paragraph continues after the environment, but to restore normal behavior if there is a \par (or empty line) after the environment.
You may want to avoid changing \end because it would have to be changed at the begining of the environment and may therefore disturb nested environments. Luckily the definition of \end contains \expandafter\endgroup\if#endpe. We can use \if#endpe as a hook to inject our code to the outer scope. After the \endgroup \if#endpe is automatically restored.
Include \#afterindentfalse\#afterheading at the end of your definition.
I had the same problem. I just used this:
\noindent \newenvironment
You should not mess with the \everypar token list, unless you know exactly what you are doing. Use
\setlength{\parindent}{0pt}
to get rid of indenting in the whole document.
ending your environment with \noindent could help you

csquotes doesn't work in this case, maybe because I'm using a custom command:
\documentclass[12pt, letter, american]{article}
\usepackage[american]{babel}
\usepackage[autopunct,style=american]{csquotes}
\newcommand{\qq}[1]{\textquote{#1}}
\begin{document}
This is an \qq{example}.
\end{document}
\qq will not move the trailing period into the quotation, e.g. This is an \qq{example}. will still yield This is an “example”. I have written a book using \qq and would like to change the quotation styles to one which moves periods and colons into the quotes. Is there a safe way to achieve this automatically? Maybe a package different from csquotes? The only solution I've found on the net so far didn't work with spacing correctly.
See the csquotes documentation, section 9.2:
\documentclass[12pt]{article}
\usepackage[american]{babel}
\usepackage[autopunct,style=american]{csquotes}
\renewcommand{\mktextquote}[6]{#1#2#4#5#3#6}
\newcommand{\qq}[1]{\textquote{#1}}
\begin{document}
This is an \qq{example}.
\end{document}
I have searched but nothing useless, only "use \newline" or "use \".
I'm creating a simple latex document to store any texts instead of using .txt, and the problem is that the pdf document contains the lines going towards right until they go out of the paper.
I'm using this simple code
\documentclass[a4paper]{article}
\usepackage{geometry}
\geometry{
a4paper,
total={170mm,257mm},
left=5mm,
top=20mm,
}
\begin{document}
\section{Text 1}

\end{document}
Since latex sees it as a one word, it refuses to break it since it doenst know its hyphenation. But I would like to allow latex to break it regardless. Any thoughts ?
Remarks: I already have used:
\hspace{0pt}
\leavevmode\nobreak\hspace{0pt}
\mbox{Loremip...larorum.}
Nothing worked.
I think I got why nothing worked. See my code below, that I managed to compile successfully after editing your MWE.
You basically have two ways to force hyphenation here.
As in the comment by SamCarter, you manually split words within text, just using \- where necessary. I did it below in line 18 (6 from bottom).
You add to your preamble the command \hyphenation{word-to-split}: I did this below to hyphenate the word in line 20 (4 from bottom). Notice that, in this case, you use - instead of \- within the braces {} enclosing the argument.
\documentclass[a4paper]{article}
\usepackage{geometry}
\geometry{
a4paper,
total={170mm,257mm},
left=5mm,
top=20mm,
}
\hyphenation{Duisauteiruredolorinre-prehenderitinvoluptatevelitesse-cillum doloreeufugiatnullapariatur}
\begin{document}
\section{Text 1}

\end{document}
Finally, if the full stop character . is not followed by a space, two separate words may be interpreted as one and the command \hyphenation may not work as expected. Not sure that this was the detail making you write that nothing worked, but be careful to this too.
I am writing a beamer presentation. My problem is a syntax issue with \section[Outline]{title}. \section is working fine with all of my section titles except in the following example:
\section[$\mathbb{Z}[G]$-module constructions]{$\mathbb{Z}[G]$-modules and Geometric Constructions}
I need a [ or \[ symbol around the G (i.e., [G]) in the Outline part of \section,however, Tex throws tons of errors whenever anything resembling a bracket is in there.
All ideas are welcome and thanks in advance.
Michael Anderson points out a much cleaner way of doing the same in the comments. Define the command in your preamble as
\newcommand[1]{\bracket}{[#1]}
and use the syntax $\bracket{G}$ to place brackets around G.
The problem is because LaTeX interprets the ] in [G] as a closing bracket for the [Outline] part of the command. Here's a work around for that. In your preamble, add the following:
\newcommand{\rbracket}{]}
Now define your section as
\section[$\mathbb{Z}[G\rbracket $-module constructions]{$\mathbb{Z}[G]$-modules and Geometric Constructions}
This is how the outline should look like
By wrapping the short title in an additional layer of {...} you can "hide" the problematic content from latex:
\documentclass{beamer}
\begin{document}
\begin{frame}
\tableofcontents
\end{frame}
\section[{$\mathbb{Z}[G]$-module constructions}]{$\mathbb{Z}[G]$-modules and Geometric Constructions}
\begin{frame}
content...
\end{frame}
\end{document}
Michael Anderson gave a nice solution, but when I tried it, I got errors. Then I wrote this:
\newcommand{\bracket}[1]{[#1]}
and that worked to get brackets in brackets with:
\bracket{content}
to get [content].
This stems out of How can one number paragraphs in LaTeX?, which I asked earlier today:
Running with Brent.Longborough's suggestion for how to number paragraphs in a document:
\setcounter{secnumdepth}{5}
...
\paragraph{If we want to}
\paragraph{do something}
This results in LaTeX producing something likeso:
0.0.0.1 If we want to
0.0.0.2 do something
How can one change the numbering scheme of \paragraph{} to produce something like:
1. If we want to
2. do something
or alternatively
A. If we want to
B. do something
Thank you.
To change the number referenced when referring to paragraphs, you want to change \theparagraph. Here's an example:
\documentclass[12pt]{article}
\setcounter{secnumdepth}{5}
\renewcommand\theparagraph{\roman{paragraph}}
\usepackage{lipsum}
\begin{document}
\paragraph{foo} \lipsum[1]
\paragraph{bar} \lipsum[2]
\end{document}
Instead of \roman you can also use \Roman, \arabic, \alph, \Alph. Although if you have lots of paragraphs you'll want to use the alphalph package and use \alphalph to get more than 26 paragraphs.
Note that \paragraph takes an argument for the "paragraph title". If you never want that, you'll probably want to define your own command to simplify things:
\newcommand\PARA{\paragraph{}}
You'll also probably want to remove the way that paragraphs are numbered "within" sections; i.e., they reset from "1" for every new section. You can get around this with something like
\usepackage{remreset}
\makeatletter
\#removefromreset{paragraph}{section}
\makeatother
How to make word 'appendix' appear in the table of contents? Right now toc looks like this:
1 ......
2 ......
.
.
A .....
B .....
I would like it to be:
1 ......
2 ......
.
.
Appendix A .....
Appendix B .....
My latex source file structure is like this:
\begin{document}
\tableofcontents
\include{...}
\include{...}
\appendix
\include{...}
\include{...}
\end{document}
There's a couple of ways to solve this problem; unfortunately, I've only got a hack for you at this stage. One problem is that if we redefine the section number "A" to include the word "Appendix", it messes up the formatting of the table of contents. So instead, I've just defined a new sectioning command that prints the section without a number and inserts "Appendix X" manually.
Kind of ugly, but at least it works without having to change any markup :)
\documentclass{article}
\makeatletter
\newcommand\appendix#section[1]{%
\refstepcounter{section}%
\orig#section*{Appendix \#Alph\c#section: #1}%
\addcontentsline{toc}{section}{Appendix \#Alph\c#section: #1}%
}
\let\orig#section\section
\g#addto#macro\appendix{\let\section\appendix#section}
\makeatother
\begin{document}
\tableofcontents
\section{goo}
\label{a}
This is sec~\ref{a}
\section{har}
\label{b}
This is sec~\ref{b}
\appendix
\section{ji}
\label{c}
This is app~\ref{c}
\subsection{me}
does this look right?
\end{document}
For my thesis, I did the following:
\appendix
\addcontentsline{toc}{section}{Appendix~\ref{app:scripts}: Training Scripts}
\section*{Sample Training Scripts}
\label{app:scripts}
Blah blah appendix content blah blah blah.
Explanation: I manually added a line to the TOC so I would have "Appendix X:..." show up in my TOC. Then I excluded the actual section command from the TOC by using an asterisk.
This is probably most easily achieved by using the appendix
package, or the memoir class.
If you don't want to use a prepackaged solution, you'll have to
hack the sectioning commands. When I needed to do this for my
dissertation, I cloned the report class, and edited until I made
the margins lady happy. What you're looking for is the
definition of the \addcontentsline macro.
The appendix package is really good and simple solution. My answer can be helpful for who wants to change chapters numbering style, for example, with using cyrillic alphabet or roman digits. The appendices numbering style is hardcoded in the \#resets#pp command (I looked in sources here http://hal.in2p3.fr/docs/00/31/90/21/TEX/appendix.sty). I solved it by simple redefining this command to my own. Just add this code into your preamble:
\makeatletter
\renewcommand{\#resets#pp}{\par
\#ppsavesec
\stepcounter{#pps}
\setcounter{section}{0}
\if#chapter#pp
\setcounter{chapter}{0}
\renewcommand\#chapapp{\appendixname}
\gdef\thechapter{\Asbuk{chapter}} % changed
\else
\setcounter{subsection}{0}
\gdef\thechapter{\Asbuk{section}} % changed
\fi
\if#pphyper
\if#chapter#pp
\renewcommand{\theHchapter}{\theH#pps.\Asbuk{chapter}} % changed
\else
\renewcommand{\theHsection}{\theH#pps.\Asbuk{section}} % changed
\fi
\def\Hy#chapapp{\appendixname}%
\fi
\restoreapp
}
\makeatother
As a result,
Appendix A
Appendix B
Appendix C
...
will change to
Appendix A
Appendix Б
Appendix В
... etc
I'm not a latex expert, and I can't guarantee this code won't break something else.
Based on #Will Robertson's answer, the code below defines the same thing but for chapter and also fixes the fact that chapter* does not add to the header when using the fancyhdr package.
With this in the preable all issues are resolved.
\makeatletter
\newcommand\appendix#chapter[1]{%
\refstepcounter{chapter}%
\def\app#ct{Appendix \#Alph\c#chapter: #1}
\orig#chapter*{\app#ct}%
\markboth{\MakeUppercase{\app#ct}}{\MakeUppercase{\app#ct}}
\addcontentsline{toc}{chapter}{\app#ct}%
}
\let\orig#chapter\chapter
\g#addto#macro\appendix{\let\chapter\appendix#chapter}
\makeatother
