WHAT IS A VERSION?

DO LIKE THIS?

SVN / CVS

SO ITS ABOUT• Basically the point is to share and backup projects • 'Easy to set up‘

1. Create the repository2. Install the client3. Use it

SET UP YOUR REPOSITORY (1 / 3)1. Download PuTTy (for example)2. Login

• Host name: ssh.itu.dk• Port: 22• Input username and password when prompted (hint: password wont show)

Connect to your repository from Tortoisesvn+ssh://<username>@ssh.itu.dk/import/home/<username>/<folder>

SET UP YOUR REPOSITORY (2 / 3)If you want a shared repository, you send an e-mail to sysadm@itu.dk with:• Group name• Purpose• User names (ITU mail)• Expire date

If you want to test it, or just want a repository for yourself, then• Use SSH to log into ITU• Use the command “svnadmin create PATH” where PATH is the FULL path of

your desired SVN repository (for example /import/home/username/svn)

SET UP YOUR REPOSITORY (3 / 3)Install the Client found at:

http://tortoisesvn.tigris.org/

USE IT!Basic SVN• Demonstration

Merging• Automated merge• Assisted merge (conflicts)• BUT this can only be done with text files like code and LaTex

Think about this, if you are alone working on a single file, no problem, but if youare 5 guys working on 25 files...

WHAT IS LATEX• Typesetting system• Uses logic to describe the document (almost like code)• Needs to be 'compiled'• Sets up the document at compile time• Chooses the most correct typesetting for you• Has a steeper learning curve• Enables the sharing of work• Can have some annoying things

RESOURCESDownload LaTex for Windows here:http://miktex.org/2.7/setup

Two editors:http://www.texniccenter.org/ (LaTex Editor)http://www.lyx.org/ (A bit “Word’ish”, but still uses LaTex)

Guide to LaTexhttp://tobi.oetiker.ch/lshort/lshort.pdf

Danish beginners guide to LaTexhttp://www.student.dtu.dk/~latex/index.php

SOME GOOD ADVICE• You have to work for it (learning by doing)• It will take some time in the beginning• You will have to search the Internet for some solutions to something (but it will

be there)• Give it a shot

THE LATEX DOCUMENTThe Preamble (the document settings)• Documentclass• Packages• Page styles

Documentclass is the type of the document, are you doing a report, an article. Think of packages of stuff you need to import, before using it... For example if you are going to do math, you need to import that math package. The pagestyles sets up, for example, headers.

The actual documentChapters, sections, text, etc

THE LATEX FLOW

A SIMPLE LATEX DOCUMENTSimple\documentclass{article}\begin{document}Small is beautiful.\end{document}

There is no packages here, just a documentclass with a class. Save it as a *.Tex file.Either use your IDE to compile it, or use pdflatex (for example pdflatex test.tex, if the path is set correctly).

A “NORMAL” LATEX DOCUMENT\documentclass[a4paper,11pt]{article}\author{H.~Partl}\title{Minimalism}\begin{document}\maketitle\tableofcontents\section{Some Interesting Words}\subsection{Some not so interesting words}\subsubsection{Boring words}Well, and here begins my lovely article.\section{Good Bye World}\ldots{} and here it ends.\end{document}

Now we have a document class with an option and a class (still no packages). We have a title and a table of contents as well.

WHATS NOWIT-intro exercises1. Create your own repository2. Create and compile a LaTex document3. Insert this LaTex document into your repository

No computer / programs (or not going to use it)• Work on your introweek project

Evaluation• REMEMBER to evaluate! The ONLY way we get better. What you have gone

through is the result of last years evaluation! (And for this check your ITU mail!)
