1.1 deraadt 38: .Sh NAME
39: .Nm fsplit
40: .Nd split a multi-routine Fortran file into individual files
41: .Sh SYNOPSIS
42: .Nm fsplit
1.3 aaron 43: .Op Fl e Ar efile Op Ar ...
1.1 deraadt 44: .Op Ar file
45: .Sh DESCRIPTION
1.6 aaron 46: .Nm
1.1 deraadt 47: takes as input either a file or standard input containing Fortran source code.
48: It attempts to split the input into separate routine files of the
49: form
50: .Ar name.f ,
51: where
52: .Ar name
1.7 aaron 53: is the name of the program unit (e.g., function, subroutine, block data or
54: program).
55: .Pp
56: The name for unnamed block data subprograms has the form
57: .Ar blkdtaNNN.f ,
1.1 deraadt 58: where NNN is three digits and a file of this name does not already exist.
59: For unnamed main programs the name has the form
60: .Ar mainNNN.f .
61: If there is an error in classifying a program unit, or if
62: .Ar name.f
63: already exists,
64: the program unit will be put in a file of the form
1.7 aaron 65: .Ar zzzNNN.f ,
1.1 deraadt 66: where
67: .Ar zzzNNN.f
68: does not already exist.
1.7 aaron 69: .Pp
70: The options are as follows:
1.8 aaron 71: .Bl -tag -width Ds
1.5 aaron 72: .It Fl e Ar efile
1.7 aaron 73: Normally each subprogram unit is split into a separate file.
74: When the
1.1 deraadt 75: .Fl e
76: option is used, only the specified subprogram units are split into separate
1.7 aaron 77: files. e.g.,
1.1 deraadt 78: .Pp
1.10 deraadt 79: .Dl $ fsplit -e readit -e doit prog.f
1.1 deraadt 80: .Pp
1.7 aaron 81: will split
82: .Dq readit
83: and
84: .Dq doit
85: into separate files.
1.1 deraadt 86: .El
87: .Sh DIAGNOSTICS
88: If names specified via the
89: .Fl e
90: option are not found, a diagnostic is written to
91: standard error.
92: .Sh HISTORY
93: The
1.6 aaron 94: .Nm
1.9 aaron 95: command appeared in

1.1 deraadt 99: .Sh BUGS
1.6 aaron 100: .Nm
1.1 deraadt 101: assumes the subprogram name is on the first noncomment line of the subprogram
1.7 aaron 102: unit.
103: Non-standard source formats may confuse
1.1 deraadt 104: .Nm fsplit .
105: .Pp
106: It is hard to use
107: .Fl e
108: for unnamed main programs and block data subprograms since you must
109: predict the created file name.
