Move .tex files from TeXlipse to TeXShop

Question

I am a newbie at LaTeX/TeXlipse/TeXShop.

I am currently writing a LaTeX document using TeXlipse plugin in Ubuntu. Due to hardware issues on the Ubuntu machine I need to port the .tex files to TeXShop on a Mac OS X. Since I was using TeXlipse, it had created all the .tex files in a project format. My entry point is document.tex

\begin{document}

%include other pages
\input{./title.tex}
%\input{./certificate.tex}

\input{./abstract.tex}
\input{./acknow.tex}
\pagenumbering{roman} %numbering before main content starts
\tableofcontents
\listoffigures

\newpage
\pagenumbering{arabic} %reset numbering to normal for the main content

\input{./introduction.tex}
\input{./systemarchitecture.tex}
\input{./implementation.tex}
\input{./experimentresults.tex}
\input{./conclusion.tex}
\input{./ref.tex}

\end{document}

When I try to preview this document.tex file I am able to see the corresponding PDF file. But any changes made to the introduction.tex file are not visible. I am not sure if this is because TeXShop does not support this kind of a project structure, or do I have to include all of the data into a single .tex file?

The error I see in the console is as follows:

/introduction.tex:3: LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
...       

Since introduction.tex is not another document but the part of a bigger document should I include \begin{document} in every .tex file?

Answer 1

In TeXShop, you can add the information of the main file (the one you're actually "compiling") using the pre-processor command:

% !TEX root = mainfile.tex

(substitute "mainfile" for whatever you're calling yours). You can also add directory indications (e.g., ./mainfile.tex).

You should use this pre-processor command in all of your "child" documents (i.e., those which you call with \include or \input from your main file).

In the TeXShop menu, go to Macros->Root->Root, to create the command.
