So, to be clear, this is what is desired?
do_something(); switch(foo) { case bar: a=1; case baz: a=2; case asd: a=3; default: a=0;
} do_something_else();
My question is this: Say I have a long case statement (dozens of cases with subsequent
processing blocks, enough
to run off both vertical edges of my screen) and it's "conveniently"
located in the middle of a large source file
with other case blocks and "normal code" above and below it. With the style
above I will have problems finding the
end of the case block, which is why I started indenting them like this:
do_something(); switch(foo) { case bar: a=1; case baz: a=2; case asd: a=3; default: a=0;
} do_something_else();
I think what is desired is something like this:
do_something();
switch(foo) {
case bar:
a=1;
break;
case baz: {
a=2;
...long case block...
c=4;
break;
}
case asd:
a=3;
break;
default:
a=0;
}
do_something_else();
The { and } in case blocks are not really needed and my preference would be not to use
them there. If needed, they
should be indented as any other block. The style in GIT adds an extra indentation level to
those {-} case blocks,
which is what Slavek and I were "complaining".
<snip> This is the current consensus as far as I
can tell: 1.) Every conditional uses braces 2.) Hard tabs 3.)
Conditional indentation like so:
if (foo) { a=0; } else if (bar) { a=1; } else { a=2; }
We still need to discuss how to handle large chains of conditionals, e.g. these
pathological cases:
https://git.trinitydesktop.org/cgit/tdelibs/tree/tdecore/tdehw/tdehardwared…
Is the style shown there acceptable?
My preference would be for breaking after the logical operator and either have no
indentation or double indentation
for the subsequent lines.
if ((disktype & TDEDiskDeviceType::CDROM) ||
(disktype & TDEDiskDeviceType::CDR) ||
(disktype & TDEDiskDeviceType::CDRW))
or
if ((disktype & TDEDiskDeviceType::CDROM) ||
(disktype & TDEDiskDeviceType::CDR) ||
(disktype & TDEDiskDeviceType::CDRW))
Also on the docket are how to handle simple variable assignments; there are several ways
I've seen: a=2; a = 2; a=
2; a =2;
I'm fairly undecided on this. For consistency with larger statements "a =
1;" should probably be used but it seems
such a waste of space compared with "a=1;". Thoughts?
Both "a=1" and "a = 1" are fine for me. For long time I used the first
way, but in the last couple of years I switched
ti the second one: usually more readable for simple expressions but can become confusing
with long and complex ones
such as:
if ((a = 2) && (++b != (c + (x * y) / f(q,w,e))))
Choice is up to you and Slavek.
One other issue is the whitespace within conditional expressions. As you can see I'm
fairly undecided on this as
well, having used multiple styles already:
https://git.trinitydesktop.org/cgit/tdelibs/tree/tdecore/tdehw/tdehardwared…
https://git.trinitydesktop.org/cgit/tdelibs/tree/tdecore/tdehw/tdehardwared…
Given a choice I slightly prefer the style shown on line 2518; my only strong preference
here is that I don't want
to see any whitespace between two matched parenthesis: Correct: execute_something()
Wrong: execute_something( )
Thoughts are welcome here as well.
Same as you, no spaces at the beginning and end parenthesis, i.e. line 2518 is
better for me.
Also, I suggest to have a space between function parameters as in
foo(par1, par2, par3, par4)
instead of
foo(par1,par2,par3,par4)
Cheers
