fsplit(1) Unsupported fsplit(1)Namefsplit - split a multi-routine Fortran file into individual files
Syntaxfsplit [-e efile...] [file]
The command takes as input either a file or standard input containing
Fortran source code. It attempts to split the input into separate rou‐
tine files of the form name.f, where name is the name of the program
unit (for example, 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 is put in a file of the form zzzNNN.f where zzzNNN.f
does not already exist.
Normally each subprogram unit is split into a separate file.
Options-e efile Splits only specified subprogram units into separate files.
The following example splits readit and doit into separate files:
fsplit-e readit -e doit prog.f
The command assumes the subprogram name is on the first noncomment line
of the subprogram unit. Nonstandard source formats may confuse
It is hard to use -e for unnamed main programs and block data subpro‐
grams since you must predict the created file name.
If names specified using the -e option are not found, a diagnostic is
written to standard error.
