-pretty=list
Controls certain messages related to
the appearance of the source code. These warn about things that might
make a program less readable or be deceptive to the reader. By default,
all warnings are turned on.
This setting provides detailed control over
the warnings about appearance. The list consists of keywords separated
by commas or colons. Since all warnings are on by default, include a keyword
prefixed by no- to turn off a particular warning. There are three special
keywords: all to turn on all the warnings about misleading appearances,
none to turn them all off, and help to print the list of all the keywords
with a brief explanation of each. If list is omitted, -pretty is equivalent
to -pretty=all , and -nopretty is equivalent to -pretty=none . The warning
keywords with their meanings are as follows:
- embedded-space:
- Space embedded
in variable names.
- continuation:
- Continuation mark following a comment
line.
- long-line:
- Lines (except comments) over 72 columns in width (beyond
72 is normally ignored by compiler).
- missing-space:
- Lack of space between
variable and a preceding keyword.
- multiple-common:
- COMMON block declared
in multiple statements. No warning is given if the statements are consecutive
except for comment lines.
- multiple-namelist:
- NAMELIST declared in multiple
statements. No warning is given if the statements are consecutive except
for comment lines.
- parentheses:
- Parentheses around a variable by itself.
As a subprogram argument, this makes the argument an expression, not
modifiable by the subprogram.
