fsplit
takes as input either a file or standard input
containing Fortran source code. It attempts to split the input into separate
routine files of the form name.f, where
name is the name of the program unit (e.g. function,
subroutine, block data or program). The name for unnamed block data
subprograms has the form blkdtaNNN.f where NNN is three
digits and a file of this name does not already exist. For unnamed main
programs the name has the form mainNNN.f. If there is an
error in classifying a program unit, or if name.f
already exists, the program unit will be put in a file of the form
zzzNNN.f where zzzNNN.f does not
already exist.
-e
efile
- Normally each subprogram unit is split into a separate file. When the
-e
option is used, only the specified subprogram
units are split into separate files. E.g.:
fsplit -e readit -e doit
prog.f
will split readit and doit into separate files.
If names specified via the -e
option are not found, a
diagnostic is written to standard error.
The fsplit
command appeared in
4.2BSD.
Asa Romberger and Jerry Berkman
fsplit
assumes the subprogram name is on the first
noncomment line of the subprogram unit. Nonstandard source formats may confuse
fsplit
.
It is hard to use -e
for unnamed main
programs and block data subprograms since you must predict the created file
name.
