LyX

Introduction

LyX is a WHYSIWYM (what you see is what you mean) Texteditor. This article not for introducing this superb wordprocessor for the LaTeX programming language, but for documententation of common solutions around running on linux operting system (mainly ubuntu).

Trouble Shooting

Fonts look ugly in PDF viewer

The reason for this mostly is, that the fonts you are using are not embedded into the PDF-file. This mostly is due to licence issues. This can lead to serious problems if you e.g. are dealing with customers or official organisations with only use proprietary software to read PDF-documents:

• https://www.sas.upenn.edu/computing/help/students/dissertation-pdf#embed

You can check, if your PDF-file has the necessary fonts embedded.

pdffonts your_file.pdf

The best way on Ubuntu (14.04 / 16.04) to get this fixed is to install the computer modern fonts package:

sudo apt-get install cm-super

• https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/261312

If you have plenty of space (app. 800 MB) you can install the package:

sudo apt-get install texlive-fonts-extra 

And or another (free) font

sudo apt-get install ttf-bitstream-vera

• viewing the german UserGuide with pdflatex

Solution for ubuntu:

sudo apt-get install lmodern

Helper Scripts

Convert all lyx files to pdflatex

Converts ALL existing lyx files in a local path or recursively into pdf files (pdflatex).

Usage:

convert_all_lyx_files_to_pdflatex { -l | -r }

#!/bin/bash

[ "${1}" == "" ] && echo "Please specify -l (local path only) or -r (recursive) as parameter." && exit 1

if [ "${1}" == "-r" ]
then
	for myfile in "$(find . -name *.lyx | awk '{print $0}' | sed -e 's/ /\\ /g')"
	do 
        	echo "${myfile}" | awk '{system("lyx --export pdf2 -f " $0);}'
	done
fi

if [ "${1}" == "-l" ]
then
	for myfile in "$(ls *.lyx | awk '{print $0}' | sed -e 's/ /\\ /g')"
	do 
        	echo "${myfile}" | awk '{system("lyx --export pdf2 -f " $0);}'
	done
fi

Pack all pdf files recursivly into a zip and tar.gz file

Searches the actual path for pdf files and packs them into a zip and tar.gz file.

Requires 7z because there are a couple of problems zipping with "gnu zip" and using utf-8!

sudo apt-get install p7zip p7zip-full

Use without any parameters.

#!/bin/bash

[ "${1}" == "" ] && echo "Please apply a filename as parameter!" && exit 1
[ -e /usr/bin/7z ] || echo "7z must be installed" || exit 1

for myfile in "$(find . -name *.pdf | awk '{print $0}' | sed -e 's/ /\\ /g')"
do 
	#echo "${myfile}" | awk '{system("zip -u zipfile.zip " $0);}'
	echo "${myfile}" | sed -e 's/.\///' | awk '{system("tar rvf tarfile.tar " $0);}'
	echo "${myfile}" | sed -e 's/.\///' | awk '{system("7z u -tzip 7zipfile.zip " $0);}'
done

gzip -f tarfile.tar
#mv zipfile.zip "${1} -  for Windows systems only.zip"
mv tarfile.tar.gz "${1}.tar.gz"
mv 7zipfile.zip "${1}.zip"

echo ----------------------------------
echo "The following files where created:"
echo ----------------------------------
#ls -lah "${1}"* | sed -e 's/ /\\ /g' | awk '{system("echo -n " $8";echo \" - size: \""$5);}'
ls -lah "${1}"*

Docbook

Docbook, Lyx and Ubuntu / Debian

To be able to use the default templates provides by lyx it is necessary to install the package sgmlutils-lite.

To be able to view and produce DVI / Postscript output you need the docbook-utils package.

sudo apt-get install sgmlutils-lite docbook-utils

So I was able to use the lyx-template docbook_article that brings very limited support for editing documents.

Hanging initials

Thanks to Initials with yinit - GER.

The yinit fonts are fine granular fonts (old style).

\usepackage{lettrine}

\usepackage{dropping}

Does NOT work with pdflatex !

\documentclass{article} 
  \usepackage [german] {babel}

hatte drei Söhne, seine Mühle, einen Esel und einen Kater; die Söhne
mußten mahlen, der Esel Getreide holen und Mehl forttragen, die Katze
dagegen die Mäuse wegfangen. Als der Müller starb, teilten sich die
drei Söhne in die Erbschaft: der älteste bekam die Mühle, der
zweite den Esel, der dritte den Kater; weiter blieb nichts für ihn übrig.

Manual (buggy)

One can also use the cmr17 fonts.

\newfont{\tmpfont}{cmr17 scaled 3000}{\tmpfont O}
\vspace*{-8ex}

\hangindent=3em \hangafter=-3

LyX on Windows

Under windows vista it is possible to export your linux default in ~/.lyx-directory.

(HINT: For other windows versions see the Lyx Wiki - section UserDir.)

Now copy your layout and templates files in the corresponding directory under

c:\Users\Your Username\AppData\Roaming\LyX<VERSION>\templates
c:\Users\Your Username\AppData\Roaming\LyX<VERSION>\layouts

<Version> defaults to e.g. <16> for the Lyx 1.6.x series.

Since MikTeX is the default TeX distribution for windows - and is bundled with the an LyX installer package - you can also alter your TeX files locally.

MikTeX also has a local directory which defaults to

c:\Users\Your Username\AppData\Roaming\MiKTex\2.8\tex\latex

There you can pack all your packages into.

After that run the administration tool of MiKTeX, refresh and update the database and formats in the General tab (Maintenance section).

Start LxX, run the reconfiguration process and restart lyx (Tools->Reconfiguration). In my case I also had to review the installed tex-informations (Tools->Tex-Informations) and read them in again, then starting the reconfiguration process.

After a LyX restart you will be prompted with all the new layouts you created.
