3.1 Input files

FWEB reads files with a variety of default extensions.

.fweb — Initialization file (optional; for setting up default options used for all runs). This file is always in the user’s home directory. See Initialization.

fweb.sty — Style file (optional; for customizing the behavior of a particular web file or group of files). See Style. This file is always in the directory of the web file that is being tangled unless that is changed by environment variable FWEB_STYLE_DIR. The basic name can be changed by the ‘-z’ option (see -z). A sample fweb.sty file is provided with the FWEB distribution.

name.web — Source file.

name.ch — Change file (optional; for making incremental changes to a web source file). See Change files.

name.hweb — Code included into web file with ‘@i’ (see ATi). Include files are searched for in the path set by the environment variable FWEB_INCLUDES and/or the ‘-I’ option (see -I_). If that path is empty, then the current directory is searched.

name.hch — Optional change file for include file.
