[Tex/LaTex] How to break lines automatically when there are inline code format

line-breaking

My TeX have a lot of inline code to compile, so sometimes the output of PDF seems like this:

The outlined part is coded in {\tt set_task_state(current_state)}, How to automatically break the line within the set_task_state(current_stat)?

Best Answer

Line breaking for monotype font is a hard issue. Below, five options (really less since some of them produce results which are not acceptable); I'd suggest you to use the listings package instead of just \ttfamily (by the way, \tt is deprecated and shouldn't ne used anymore) to write your listings. I loaded showframe to have a visual guide of the text area.

\documentclass{article}
\usepackage{listings}
\usepackage{underscore}
\usepackage{showframe}

\lstset{
  basicstyle=\ttfamily\small,
  columns=fullflexible,
  breaklines=true
}

\begin{document}

The method {\ttfamily set_current_state(current_state)} is synonimous to {\ttfamily set_task_state(current_state)}

The method \lstinline|set_current_state(current_state)| is synonimous to \lstinline|set_task_state(current_state)|

{\sloppy
The method \lstinline|set_current_state(current_state)| is synonimous to \lstinline|set_task_state(current_state)|\par}

{\sloppy
The method {\ttfamily set_current_state(current_state)} is synonimous to {\ttfamily set_task_state(current_state)}\par}  

{\raggedright
The method \lstinline|set_current_state(current_state)| is synonimous to \lstinline|set_task_state(current_state)|\par}

{\raggedright
The method {\ttfamily set_current_state(current_state)} is synonimous to {\ttfamily set_task_state(current_state)}\par}

{{\ttfamily\hyphenchar\the\font=`\-}%
The method {\ttfamily set_current_state(current_state)} is synonimous to {\ttfamily set_task_state(current_state)}\par}

\end{document}

The result

Some comments

Using linebreaks=true enables line-break points; however, in this case, the verbatim text still protrudes.

Using sloppy leaves horrible big gaps between words.

Using \raggedright gives a somehow better and acceptable result here.

[Tex/LaTex] break lines in minted code

Version 2.1 of minted has breaklines and linenos:

\documentclass[a5paper]{article}
\usepackage[T1]{fontenc}
\usepackage[]{minted}

\begin{document}
\begin{minted}[linenos,tabsize=2,breaklines]{text}
output {
    elasticsearch {
        host => "192.168.229.133"
    }

    statsd {
        sender => "%{datacenter}"
        increment => [ "%{server}.%{project}.%{web}.iis.response. %{response}" ]
        timing => [ "%{server}.%{project}.%{web}.iis.servetime", "%{time-taken}" ] 
        count => [ "%{server}.%{project}.%{web}.iis.bytessend", "%{bytessend}", "%{server}.%{project}.%{web}.iis.bytesreceived", "%{bytesreceived}" ]

[Tex/LaTex] How to align lines and automaticaly break the lines if they are too long

An equation-oriented environment such as align* isn't well suited for the task at hand. Instead, consider using a table-like environment such as tabularx.

The following code uses the construct @{${}={}$} to insert a properly-spaced = symbol between the first and second column of the tabularx environment; the X column type, used for the second column, "wraps" its contents automatically as needed. The overall width of the table is set to 0.75\textwidth -- adjust this setting as you see fit.

\documentclass{article}
\usepackage{tabularx}
\begin{document}

\begin{center}
\begin{tabularx}{0.75\textwidth}{>{$}r<{$} @{${}={}$} X}
  n &number of days in the support and resistance range; \\
  e &used for an alternative definition of extrema where 
     a low (high) can be defined as the most recent closing     
     price that is less (greater) than the n previous closing 
     prices; \\
  b &fixed band multiplicative value.\\
\end{tabularx}
\end{center}
