Node:Syntax, Next:Options, Previous:Starting, Up:Starting
The command-line syntax is
{ftangle | fweave} [-option...] webfile[.web] [changefile[.ch]]
A file name is anything that doesn't begin with a -
, except that
a lone hyphen stands for the special file name
stdin
, which means `read from the standard input.' (This should
not be used except for very special effects.)
Command-line options begin with a -
. File names and options can
be intermixed, or the
options may appear after the file names. The first file name
encountered is the web source file; the second, if it exists, is
the change file (see Change files). [When no change file is
specified, FWEB attempts
to read from the null file (/dev/null
on UNIX systems). This
name should be specified when FWEB is installed
(see Customization), or can be set in the style file fweb.sty
.
See null_file.]
The web file is shown as required since one is normally processing a
source. However, some of the information options (see Info options)
will work without specifying any file name. For example, one can obtain a
list of all of the style-file parameters and their default values by saying
ftangle -Z
.
