I want to provide some structure for my thesis source files. I decided to use nested directories. Every directory contains main.tex index file to be imported by a file in the parent directory.

From Path to External Files in Nested \input I learned about import package, however it is not working for me.

For the simplest case

/
+- main.tex: |\documentclass{report}
|            |\usepackage{import}
|            |\begin{document}
|            |main
|            |
|            |\subimport{a}{main.tex}
|            |\end{document}
+- a/
    +- main.tex: |a main

I expect to have result like:

main

a main

Instead, I get the following error during compilation:

$ pdflatex main

l.1 \documentclass
                  {report}

\subimport{a}{main} nor \subimport{a/}{main} neither works.

How can I tell the import package not to look for import files in the root directory? Also I wonder, if the issue won't occur in subdirectories too (at the moment I was unable to cause it).

  • The best way is to have unique names ... – Zarko Feb 8 '17 at 20:49
  • why use \import at all? just use \input{a/main} but i see no advantage in giving multiple files the same name. – David Carlisle Feb 8 '17 at 21:00
  • @Zarko: names are unique within a directory – abukaj Feb 8 '17 at 21:04
  • @DavidCarlisle: imagine length of a path for file in sub-sub-subdirectory, all directories with meaningful names. Then imagine that for some reason I may want to move/rename one of the directories with minimal effort. – abukaj Feb 8 '17 at 21:08

    the input all need to be relative to the working directory – David Carlisle Feb 8 '17 at 21:30
