\input file
file name of the file


The command \input filename is replaced by the content of the text file filename.

When no file extension is specified the extension .tex is assumed.

Unlike the case with project structure commands such as \environment, \input will not cause ConTeXt to look in parent directories for the specified file (unless of course the given filename is actually a path beginning with ../ or the equivalent).


We have two files, each containing a chapter:

% chapter-01.tex
\subject{Chapter 1}

This is the first chapter.
% chapter-02.tex
\subject{Chapter 2}

This is the second chapter.

The book file inputs both chapters:

% complete-book.tex

% No extension specified, so .tex assumed
\input chapter-01
\input chapter-02


Compiling book.tex produces the following:

See also

  • \ReadFile: Similar to \input but the filename is specified as an argument
  • \readfile: Similar to \ReadFile with additional options when file is not found.
  • \getbuffer: Get back the "formatted" content of a buffer.
  • \typebuffer: Get back the content of a buffer as verbatim text.
  • \typefile: Print a file verbatim
  • \component and \environment for input commands with more descriptive names.
  • Dummy text for other ways to produce filler text

Default input files

ConTeXt includes a number of files that you can use with \input when you quickly need some filler text.
