# Simplified LNCS Template



> Quick start for modern LaTeXing with [LNCS](http://www.springer.com/computer/lncs).



To build the whole document, execute following command.

Note that this requires a working perl installation.



    latexmk paper



In case something goes wrong, you can instruct the LaTeX compiler to stop at the first error:



    pdflatex paper



## Benefits



Following features are enabled in this template:



- Provides a skeletal [paper.tex](https://latextemplates.github.io/LNCS/paper.tex) file

- Example to have an image being placed right to a text

- Automatic setting of "Fig." and "Section"/"Sect." according to the LNCS style.

  Just use `\Cref{sec:xy}` at the beginning of a sentence and `\cref{sec:xy}` in the middle of a sentence.

  Thanx to [cleveref].

- Sharper font (still compatible with Springer's requirements).

- (Optional) Typesetting of listings using advanced highlighting powered by the [minted] package.

- Generated PDF allows for copy and paste of text without getting words with ligatures such as "workflow" destroyed.

  This is enabled by `glyphtounicode`, which encodes ligatures (such as fl) using unicode characters.

- Support of hyperlinked references without extra color thanx to [hyperref].

- Better breaking of long URLs.

- Support for `\powerset` command.

- (Optional) Support todos as pdf annotations. This is enabled by the [pdfcomment] package.

- [microtypographic extensions](https://www.ctan.org/pkg/microtype) for a better look of the paper.

- Modern packages such as [microtype], [cleveref], [csquotes], [hyperref], [hypcap], [upquote], [natbib], [booktabs].

- (Optional) LaTeX compilation using the modern lualatex compiler.

- Ready-to-go configuration for [latexindent].



## Disabled features



Following features were not activated for this template.

You can run the [latex template generator] to enable the features.



Hints on writing an abstract and thesis by Dirk Fahland.



## Examples



- [paper.pdf](https://latextemplates.github.io/LNCS/paper.pdf) - normal paper.

- [paper-minted.pdf](https://latextemplates.github.io/LNCS/paper-minted.pdf) - paper showing minted in action.

- [paper-newtx.pdf](http://latextemplates.github.io/LNCS/paper-newtx.pdf) - paper typeset in Times Roman to save some space.

- [paper-minted-newtx.pdf](http://latextemplates.github.io/LNCS/paper-minted-newtx.pdf) - paper typeset in Times Roman to save some space.



## Background



The official template is available at  --> "Templates, samples files & useful links" --> "LaTeX2e Proceedings Templates (zip)"



## Quick start



- Click on `Download ZIP` or [here](https://github.com/latextemplates/LNCS/archive/main.zip).

- Extract `LNCS-main.zip` in the folder where you want to write your paper.

- Edit [paper.tex](paper.tex).

- `latexmk paper`.



When using on overleaf, you have to switch Overleaf to use TeXLive 2022 (or later).



As you see on GitHub actions, the paper compiles out of the box.

There is no need to adjust the packages or to remove some of them.

This might lead to undesiered results such as hyperlinks not working any more or no good microtypographic features.

In case you think, a package needs to be altered or added, feel free to open an issue.



## Tool hints



There is currently no official biblatex support.

A first step towards that is done at [biblatex-lncs](https://ctan.org/pkg/biblatex-lncs).



MiKTeX installation hints are given at .



- Grammar and spell checking is available at [TeXstudio].

  Please download [LanguageTool] (Windows: `choco install languagetool`) and [configure TeXstudio to use it](http://wiki.languagetool.org/checking-la-tex-with-languagetool#toc4).

  Note that it is enough to point to `languagetool.jar`.

  **If TeXstudio doesn't fit your need, check [the list of all available LaTeX Editors](http://tex.stackexchange.com/questions/339/latex-editors-ides).**

- Use [JabRef] to manage your bibliography (Windows: `choco install jabref`).



To have minted running properly, you have to do following steps on Windows:



1. Install python: `choco install python` - that uses [chocolatey](https://chocolatey.org/) to install Python

2. Install [pygments]: `pip instal pygments` - that uses the Pyhton package manager to install the pygments library

3. When latexing, use `-shell-escape`: `pdflatex -shell-escape paper`.

   You can also just execute `latexmk paper`.



## Usage with docker



The generated `Dockerfile` is based on the [Dockerfile by reitzig](https://github.com/reitzig/texlive-docker).

The idea of that system is to host the document sources in a directory separated from the output directory.



    docker run --rm -v "c:\users\example\latex-document:/work/src" -v "c:\users\example\latex-document\out:/work/out" ltg work latexmk



Following one-time setup is requried:



    docker build -t ltg .



## FAQs



### Q: ShareLaTeX outputs a warning regarding the llncs class



ShareLaTeX might output following warning:



> LaTeX Warning: You have requested, on input line 8, version

> 2018/03/10' of document class llncs, but only version 2004/08/17 v2.14

> LaTeX document class for Lecture Notes in Computer Science'

> is available.



The reason is that you did not use `llncs.cls` (included in your LaTeX distribution).

Please remove the file and update your LaTeX distribution.



### Q: How can I synchronize updates from the template to my repository?



1. Initialize your git repository as usual

2. Add this repository as upstream: `git remote add upstream https://github.com/latextemplates/LNCS.git`

3. Merge the branch `upstream/main` into your `main` branch: `git merge upstream/main`.



After that you can use and push the `main` branch as usual.

Notes on syncing with the upstream repository [are available from GitHub](https://help.github.com/articles/syncing-a-fork/).



### Q: I get the error  `! pdfTeX error (font expansion): auto expansion is only possible with scalable fonts.`



Install the `cm-super` package using the MiKTeX package manager. Then, run `initexmf --mkmaps` on the command line. (Long description: )



### Q: I get `Package csquotes Error: Unbalanced groups or invalid nesting.` What can I do?



A: You have activated `\MakeOuterQuote{"}` and used some special babel command to allow hyphenation at other places as a dash. One example is writing `application"=specific`.

Now, you have to decide whether you want keep using plain quotes to enquote a word or use the special hyphenation command.

In other words: Do you want `"quote"` and `app\-lication\-specific` or `\enquote{quote} and  application"=specific`?



Note that this should not happen when the template is generated as the setting `tweakouterquote` ensures that these two options are mutually exclusive.



### Q: I need more space. What can I do?



The most simple solution to get more space is to exchange the font.



### Q: How can I reformat my `.tex` files?



Execute following command:



    latexindent -l -s -sl -w paper.tex



### Q: I want to obey the one-sentence-per-line rule. How can I do that?



Execute following command:



    latexindent -m -l -s -sl -w paper.tex



Attention! This is work in progress and does not always produce best results.



### Q: Is it possible to have a footer indicating that the paper is intended to be submitted/submitted/published?



Activate the `llncsconf` package.

The possible options are listed in `paper.tex`.



### Q: Can I also write in German?



Yes. You can regenerate the template and choose "German" as language.
