TeXstudio Settings – Understanding the ‘Long Range Repetitions’ Feature

texstudio

I am trying to adjust TeXstudio's settings so that it only highlights a word which is repeated immediately immediately (like I just did). "Aardvark Banana Aardvark" should not be highlighted.

My TeXstudio settings page looks like this:

What is a "Long Range Repetition"? How is it different from a regular repetition? My best guess is that:

Words Between Repetitions = 3 means that the second Aardvark is flagged in "Aardvark 1 2 3 Aardvark" but not in "Aardvark 1 2 3 4 Aardvark"
Min Length of Words with Long Repetition = 6 means that "12345" would be ignored when searching for long range repetitions, but "123456" would not

But Long Range Repetitions = 10 is completely opaque to me. If I want to turn

Best Answer

The wording is a bit confusing but apparently "long range" means "long words", so words with a minimal length (as specified in the option below).

From https://github.com/texstudio-org/texstudio/blob/master/src/configdialog.ui:

Equal words are marked as repetition if there are no more than this number of words between them.

Equal, longer words are marked as long range repetition if there are no more than this number of words between them.

Only words with have this length are checked for long range repetitions.

TeXStudio Error – Does Not Recognize \colon

The macro \colon is defined in plain.tex as a punctuation mark (: is a relation symbol in math mode)

\mathchardef\colon="603A

and redefined by amsmath.

Unfortunately, TeXstudio doesn’t recognize the command even if the amsmath.cwl completion file is selected.

But we can create our own .cwl file. On Windows, custom .cwl files are stored and recognized by TeXstudio in %appdata%\texstudio\completion\user. In Linux in ~/.config/texstudio/completion/user. (more information in 4.13.4 cwl file placement)

Create your own .cwl file, I named it custom.cwl. One line suffices:

\colon#m

Notes:

m declares it as a math mode command, the use of \colon in text mode will still give you the unrecognized highlighting.
S, as I understand it, gives you recognizing (i.e. correct highlighting) but not completion.

After saving the file custom.cwl start TeXstudio go to the “Options” menu and open the “Configure TeXstudio” dialog. In the “Completion” tab select custom.cwl and apply your changes (“OK”).

Code

\documentclass{article}
\begin{document}
$a:b$\par
$a{:}b$ \par
$a\mathrel{:}b$ \par
$a{:\,}b$ \par% \colon
$a\colon b$ \par
a \colon b
\end{document}

TikZ-PGF – Gnuplot-TikZ-TeXstudio Setting Problem

I think you are a little bit confused about TikZ capabilities and of course the package pgfplots. First problem is that you need to let pdflatex or whichever engine you are using to reach out the system commands. For example, I use TeXnicCenter and my command line parameters are configured as

-synctex=-1 -max-print-line=120 -interaction=nonstopmode "%wm" -shell-escape

The last bit allows for system calls (and the "%wm" bit is equivalent to your %.tex). And direct compilation of your code gives me

but I don't have TeXStudio so I couldn't test it. However the idea is essentially the same.

Alternatively you can use TikZ or pgfplots for plotting functions if your function is not really esoteric or complicated.

Here are two examples :

In TikZ you replace one line of your code with

\draw plot (\x,{sin(\x r)}) node[right] {$f(x) = \sin x$};

And in pgfplots with default settings

\documentclass[a4paper]{article}
\usepackage{pgfplots,mathrsfs}

\begin{document}
\begin{tikzpicture}
\begin{axis}[axis lines=middle,xmax=6,ymin=-1,ymax=1]
    \addplot[domain=0:4] {sin(deg(x))} node[right]{$f(x)=\sin(x)$};
\end{axis}
\end{tikzpicture}
\end{document}
