I have a fairly large document, that I have picked apart into different sections etc, each in their own file. To include graphics that are not in one central directory I use \graphicspath which works quite nicely. Is there a similar command I could use to include tex files from multiple directories without me explicitly naming them?

The idea would be the following:


The I would like to call within the document:

\includegraphics{fig_from_Figures1}% this works

\input{doc_from_Files1}% this would be awesome

The facility used by the graphics package is in fact really for tex input files, it just locally redefines the path for graphics. Just define \input@path with the same syntax:

Graphics defines


and then locally within \includegraphics sets


so if instead you just globally defined \input@path it would affect \input{} and \read.

However for both TeX files and graphics I would probably not use this mechanism (even though I implemented it) but instead just set TEXINPUTS=.//: before running LaTeX and then all subdirectories of the current directory will be searched anyway.

  • Is there a particular reason you avoid these graphics and tex file path definitions?

    @Markus, well mainly the kpathsea search algorithm is implemented in C and the latex input@path algorithm is implemented in TeX macros and is a gazillion times slower. Aug 13 '13 at 20:45
