anything else

Hey,

I played around with some line wrapping options and I experienced that after a \[ \] there is no indentation inside the {}, after a subsection there is one tab indentation and after a section there is 1/2 tab indentation.

Is there an option to make this consistent e.g. never indent the code inside {} like after the \[ \]?

Thanks for looking into this.

EDIT: some additional examples

[cmhughes]

Have you tried

noAdditionalIndentGlobal:
  UnNamedGroupingBracesBrackets: 1

[domi413]

\documentclass[10pt, a4paper]{article}
\usepackage{amsmath}

\begin{document}
\section{first section}
\[ f(x) = \sqrt{e^x} = \left(e^{x}\right)^{\dfrac{1}{2}} = e^{\dfrac{1}{2}x} \]

{ \small
\begin{align*}
	f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
\end{align*}
}

\( x_0 \)

{ \small
	\begin{align*}
		f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
	\end{align*}
}

hello world

	{ \small
		\begin{align*}
			f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
		\end{align*}
	}

\subsection{subsection}
{ \small
	\begin{align*}
		f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
	\end{align*}
}

\section{Other section}
 { \small
  \begin{align*}
	  f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
  \end{align*}
 }
\end{document}

A bit better compared to the previous result, but still some odd formatting

[cmhughes]

Can you make sure this is as minimal and clear as possible please? One specific example at a time.

[domi413]

sorry for the delay.

Here's a minimal .latexindent.yaml

defaultIndent: "\t"

noAdditionalIndentGlobal:
  UnNamedGroupingBracesBrackets: 1

input tex file:

\documentclass[10pt, a4paper]{article}
\usepackage{amsmath}

\begin{document}
\( x_0 \)

{ \small
	\begin{align*}
		f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
	\end{align*}
}
\end{document}

desired output:

\documentclass[10pt, a4paper]{article}
\usepackage{amsmath}

\begin{document}
\( x_0 \)

{ \small
\begin{align*}
	f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
\end{align*}
}
\end{document}

actual output:

\documentclass[10pt, a4paper]{article}
\usepackage{amsmath}

\begin{document}
\( x_0 \)

{ \small
	\begin{align*}
		f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
	\end{align*}
}
\end{document}

As you can see, the \begin{align*} is indented, but it should not.

[cmhughes]

Thanks for this.

Using the following gives your desired output

defaultIndent: "\t"

noAdditionalIndent:
  always-un-named:
    body: 1
    mandatoryArguments: 1
    optionalArguments: 1

This is sort of mentioned in https://latexindentpl.readthedocs.io/en/latest/sec-default-user-local.html#unnamedgroupingbracesbrackets but I don't think it has enough details.

I'll update the documentation to cover this, so please leave this issue open :)

[domi413]

Hey, thanks for the answer :)

unfortunately, it looks like that those configs "only" fixes 1/4 cases.

Here are the remaining cases, that (with the above formatter settings) still have some indenation

\documentclass[10pt, a4paper]{article}
\usepackage{amsmath}

\begin{document}
hello world
	{ \small
		\begin{align*}
			f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
		\end{align*}
	}

\subsection{subsection}
{ \small
	\begin{align*}
		f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
	\end{align*}
}

\section{Other section}
 { \small
  \begin{align*}
	  f(x) & = e^{\dfrac{1}{2} x} &  & \Rightarrow f(0) = e^0 = 1 \\
  \end{align*}
 }
\end{document}

[cmhughes]

The following gives your desired output:

defaultIndent: "\t"

noAdditionalIndentGlobal:
  mandatoryArguments: 1
  namedGroupingBracesBrackets: 1

indentRules:
  section: ''
