findent - Indents and optionally converts Fortran program
source
findent [OPTION]...
Findent reads from STDIN and writes to STDOUT.
Findent indents a Fortran source. Findent uses various kinds of
indentations, see OPTIONS. Findent can convert from fixed form to free form,
and can supplement single 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>.
Errors in OPTIONS are silently ignored.
Below: <n> denotes an unsigned decimal number. 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
- -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
- -ofree,
--output_format=free
- force free format output
- -osame,
--output_format=same
- output format same is input format
- -Rr,
--refactor_procedures
- refactor procedures and modules: a single 'end'
is, if possible, replaced by
'end subroutine <name>' or
'end function <name>' or
'end program <name>' or
'end blockdata <name>' or
'end module <name>'
where <name> is the name of the appropriate block
- -RR,
--refactor_procedures=upcase
- same as -Rr, but 'SUBROUTINE' in stead of 'subroutine' etc
- -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>,

- ENUM indent
- -F<n>,
--indent_forall=<n>
- FORALL indent
- -j<n>,
--indent_interface=<n>
- INTERFACE indent
- -m<n>,

- -x<n>,
--indent_critical=<n>
- CRITICAL 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
