As reference, here are the options of findent:
~/findent-3.1.7$ findent -h
findent [options]
Format fortran source.
Findent reads from STDIN, writes to STDOUT.
Findent uses various kinds of indentations, see OPTIONS.
Findent can convert from fixed form to free form and vice versa and
can supplement END statements, see 'Refactor' below.
Comment lines with '!' in column one are not indented.
You can correct findent related indenting errors by
inserting comment lines:
! findentfix: <fortran statement>
where <fortran statement> is for example DO, END, WHERE() etcetera.
Findent will adjust the indentation according to <fortran statement>.
OPTIONS (errors are silently ignored):
General options:
Below: <n> denotes an unsigned decimal number.
<c> denotes a character.
In the long options, you can replace '_' with '-'.
-h, --help : print this text
-H, --manpage : print man page
--readme : print some background information
-v, --version : prints findent version
-q, --query_fix_free : guess free or fixed, prints 'fixed' or 'free' and exits
--continuation=<c> : ' ': (default) do not change continuation characters
'0': create numbered continuation characters
other: use that continuation character
default for conversion from free to fixed is '&'
--include_left=<n> : (0/1) 1: indent include statements to starting indent (default:0)
-l<n>, --label_left=<n> : (0/1) 1: move statement labels to start of line (default:1)
(only for free format)
-lastindent, --last_indent : prints computed indentation of last line
(for usage with vim)
-lastusable, --last_usable : prints line number of last line usable
as start for indenting(for usage with vim)
-iauto, --input_format=auto : determine automatically input format (free or fixed)
-ifixed, --input_format=fixed : force input format fixed
(default: auto)
-ifree, --input_format=free : force input format free
(default: auto)
-i-, --indent=none : do not change indent (useful in combination with -R)
-L<n>, --input_line_length=<n> : use only first <n> characters of each line
default=0: take whole lines
-L<n>g, --input_line_length=<n>g : same as above, but use gfortran convention
for counting the characters with tabbed lines
example: --input_line_length=72g
-M<n>, --max_indent=<n> : maximum output indent, default 100, 0: no limit
-ofixed, --output_format=fixed : force fixed format output
-ofree, --output_format=free : force free format output
-osame, --output_format=same : output format same is input format
--openmp=<n> : 0: do not indent openmp conditionals
1: indent openmp conditionals (default)
NOTE: for free format, the omp sentinel must be '!$ '
-Rr, --refactor_procedures : refactor procedures and modules: the END line
of a subroutine, program etc. is, if possible, replaced by
'end subroutine <name>' or
'end function <name>' or
'end procedure <name>' or
'end program <name>' or
'end block data <name>' or
'end module <name>' or
'end submodule <name>'
where <name> is the name of the appropriate procedure, subroutine etc.
NOTE1: if the END line contains a continuation the results are undefined
NOTE2: a line like 'end function fun' will be replaced by
'end subroutine sub' if the END line ends 'subroutine sub'
-RR, --refactor_procedures=upcase : same as -Rr, but 'END SUBROUTINE <name>'
in stead of 'end subroutine <name>' etc.
Indenting options:
-I<n>, --start_indent=<n> : starting indent (default:0)
-Ia, --start_indent=a : determine starting indent from first line
-i<n>, --indent=<n> : all indents except I,c,C,e (default: 3)
-a<n>, --indent_associate=<n> : ASSOCIATE indent
-b<n>, --indent_block=<n> : BLOCK indent
-d<n>, --indent_do=<n> : DO indent
-f<n>, --indent_if=<n> : IF indent
-E<n>, --indent_enum=<n> : ENUM indent
-F<n>, --indent_forall=<n> : FORALL indent
-j<n>, --indent_interface=<n> : INTERFACE indent
-m<n>, --indent_module=<n> : MODULE indent
-r<n>, --indent_procedure=<n> : FUNCTION,
SUBROUTINE and PROGRAM indent
-s<n>, --indent_select=<n> : SELECT indent
-t<n>, --indent_type=<n> : TYPE indent
-w<n>, --indent_where=<n> : WHERE indent
-x<n>, --indent_critical=<n> : CRITICAL indent
--indent_changeteam=<n> : CHANGE TEAM indent
-C-, --indent_contains=restart, : restart indent after CONTAINS
-k<n>, --indent_continuation=<n> : continuation indent except
for lines starting with '&'
free to free only
-k-, --indent_continuation=none : continuation lines not preceded
by '&' are untouched
free to free only
: next defaults are: all - all/2
-c<n>, --indent_case=<n> : CASE negative indent
-C<n>, --indent_contains=<n> : CONTAINS negative indent
-e<n>, --indent_entry=<n> : ENTRY negative indent
Dependencies:
--deps : output dependency information only, other flags are ignored.
This can be used to generate a dependencies file for usage with make(1).
The format of this information:
Fortran source -> findent output
include "file1" -> inc file1
#include "file2" -> cpp file2
#include <file3> -> std file3
??include 'file4' -> coc file4
use module1 -> use module1
submodule(m) subm -> use m
mod m:subm
module module2 -> mod module2
--makefdeps : outputs a sh(1) script that serves as a an example
to generate dependencies for use in make(1).
