Add blank line before every section marker?

[alok]

I want something like

\section
...

to always have a blank line inserted between if there isn't one already. I looked at the modifyLineBreaks settings but wasn't able to figure it out.

Please provide examples of what your code looks like before and what you would like it to look like after.

[alok]

before

\section{Introduction}
A sentence

after

\section{Introduction}

A sentence.

[cmhughes]

This is not possible with the current implementation of latexindent.

If you started with

\section{introduction} a sentence

then we could produce

\section{introduction}

a sentence

using

modifyLineBreaks:
    mandatoryArguments:
        RCuBFinishesWithLineBreak: 3

I'm not in a position to say that I can take this on. It would mean the full development of a new polyswitch; furthermore, every single one of the core regular expressions would need overhauling, which would represent an absolutely massive task. Sorry about this.

[cmhughes]

A work around is to run latexindent twice, as follows:

alok1.yaml

modifyLineBreaks:
    mandatoryArguments:
        section:
            RCuBFinishesWithLineBreak: -1

and

alok2.yaml

modifyLineBreaks:
    mandatoryArguments:
        section:
            RCuBFinishesWithLineBreak: 3

and then run

latexindent -m -o=+-mod1 -l=alok1.yaml myfile.tex
latexindent -m -l=alok2.yaml myfile-mod1.tex

and you'll receive your desired output.

I've been thinking about this a lot.

Since I posted my work around, I've been wondering if the internal calls to the relevant polyswitch/line break parts could be tweaked in such a way so that if, for example, a polyswitch is specified as 4 could the polyswitch/line break parts be called first of all with a temporary value of -1 (line break removal) and then with a value of 3 (add blank line mode)....

This would mean that the core regular expressions would be left alone (win!) and that the testing would not be too arduous because the new polyswitch is formed by combining existing ones....

I'm going to reopen this issue, and commit to exploring this idea. I'll report back.

[cmhughes]

As of cd8312d, a new poly-switch value of 4 is implemented which facilitates the feature you describe.

If you start with

section1.tex

\section{Introduction}
A sentence

and the YAML:

tmp.yaml

modifyLineBreaks:
    mandatoryArguments:
        RCuBFinishesWithLineBreak: 4

and run

latexindent.pl -m  section1.tex -l=tmp.yaml

then you receive

\section{Introduction}

A sentence

I'm preparing a new release soon.

Thanks for getting in touch!

Implemented as of #169 upload to ctan soon.
