[Tex/LaTex] How to include tex files

formattingincludeinput

Is there any way that I can add different .tex files (From different folders) into another folder's .tex file?

I meant that all of the .tex files will be fine and separated and I just need to aggregate into one without copy & pasting these files into a single one.

enter image description here

I have saved the input file like this, but it's not working when I write in another file,
like enter image description here

\include{oscillonsource.tex}.

It's still not working. 🙁

Here is a complete example of the input/include command at work:

The example consists of 3 files in a folder structure as follows:

[Parent Folder]
 |
 +-- file1.tex
 |
 +-- fig.jpg
 |
 +-- [folder]
      |
      +-file2.tex

fig.jpg is just an ordinary jpg image file. The contents of file1.tex are as follows:

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\input{folder/file2.tex}
\end{document}

Note the inclusion of the (relative) path as well as the filename of file2.tex.

The contents of file2.tex are

\includegraphics{fig.jpg}

Note that file2.tex does not have its own preamble, document class, \begin{document} etc.

Think of \input as having a similar effect to you manually copying and pasting whatever is in file2.tex into file1.tex: no need to include anything you wouldn't want to copy in this fashion. Following through this copying/pasting logic: note also that the path to fig.jpg needs to be relative to file1.tex, not file2.tex. Since fig.jpg is in the same folder as file1.tex this means that we don't have to specify any path.

Saving this file/folder structure and compiling file1.tex results in a document with fig.jpg included in it.

[Tex/LaTex] How to include files in subfolders

I am not sure of want you have in this files and what you want obtain, but supposing that you have a main file book.tex in the directory "Bellankonda", and files as chap_page_015 are only chunks of body text (no fully compilable LaTeX documents) and you want obtain a unique PDF merging all these chunk, then the book file could be somethig as this:

\documentclass{book}
\begin{document}
\input{Chapter_02/chap_page_015}
\input{Chapter_02/chap_page_016}
\input{Chapter_02/chap_page_017} 
% etcetera
\end{document}

If the subfiles are something as whole chapters, that must start-end newpages, may be you want use \include instead of \input. Please see When should I use \input vs. \include?

If the child documents are complete LaTeX files with preamble (starting with \documentclass and ended with \end{document} you can use the same file put including in the preample the packages standalone, or docmute, or subfiles (in this case use \subfiles instead of \input). The child documents must be all of the same class, in other case, you can try the combine class, but usually this usually this means asking for troubles. Another option in this case could be produce PDF files of individual pages and merge all with pdfpages package.

Edit

As the comment of Aku ask for a loop to write automatically the \input commands, a solution could be the \foreach command. The code below is a simple example where the main document include from page1.tex to page5.tex using this command:

% Main file  
\documentclass{article}
\usepackage{tikz}
\begin{document}
 \foreach \c in {1,...,5}{\input{page\c.tex} }
\end{document}

With the subdocuments made from the commandline in this way:

echo " page {\em number 1}\par " > page1.tex  
echo " page {\em number 2}\par " > page2.tex  
echo " page {\em number 3}\par " > page3.tex  
echo " page {\em number 4}\par " > page4.tex  
echo " page {\em number 5}\par " > page5.tex

The results must be the following:

[Tex/LaTex] Include tex-files and compile separately

While there are packages I'd use the standard latex \include functionality.

Put each chapter in a separate file (starting \chapter not \documentclass) and use \label and \ref freely across chapters. have a main.tex that looks like

\documentclass{book}
% \includeonly{chapter2}
\begin{document}
\include{chapter1}
\include{chapter2}
\end{document}

When you are working on chapter 2 uncomment the \includeonly and just chapter2 will be processed. References to chapter 1 will still work so long as the .aux file from previous runs that included chapter 1 are still around.
