NAME
findent - Indents and optionally converts Fortran program source
SYNOPSIS
findent [OPTION]...
Findent reads from STDIN and writes to STDOUT.
DESCRIPTION
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.
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).
Environment:
findent parses the environment variable FINDENT_FLAGS before the command-line flags
Usage with vim:
--vim_help
outputs directions to use findent in (g)vim
--vim_fortran
outputs file 'fortran.vim', see --vim_help
--vim_findent
outputs file 'findent.vim', see --vim_help
Usage with gedit:
--gedit_help
outputs directions to use findent in gedit
--gedit_external
outputs script 'findent-gedit', see --gedit_help
--gedit_plugin
outputs file 'findent.plugin', see --gedit_help
--gedit_plugin_py
outputs file 'python.py', see --gedit_help
Usage with emacs:
--emacs_help
outputs directions to use findent in emacs
--emacs_findent
outputs script 'findent.el', see --emacs_help
Examples:
indent: findent < in.f > out.f
findent -i2 -r0 < in.f > out.f
convert fixed to free form: findent -ofree < prog.f > prog.f90
convert free to fixed form: findent -ofixed < prog.f90 > prog.f
refactor 'end': findent -Rr < in.f90 > out.f90
BUGS:
* Also for free-format, findent is space-insensitive, while the standard states that
space must be used as general separator.
* There are some issues with labels in a continuation when converting from free to
fixed format. For example:
123&
4 continue
The problems arise because it is not possible to define a statement label in a
continuation in fixed format.
* When converting from fixed format to free format, findent discards white space in a
string if the string contains a continuation, e.g:
print *,"a
+b"
is converted to:
print *,"a&
&b"
