1+
QEMU Coding Style
2+
=================
3+
4+
Please use the script checkpatch.pl in the scripts directory to check
5+
patches before submitting.
6+
7+
1. Whitespace
8+
9+
Of course, the most important aspect in any coding style is whitespace.
10+
Crusty old coders who have trouble spotting the glasses on their noses
11+
can tell the difference between a tab and eight spaces from a distance
12+
of approximately fifteen parsecs. Many a flamewar have been fought and
13+
lost on this issue.
14+
15+
QEMU indents are four spaces. Tabs are never used, except in Makefiles
16+
where they have been irreversibly coded into the syntax.
17+
Spaces of course are superior to tabs because:
18+
19+
- You have just one way to specify whitespace, not two. Ambiguity breeds
20+
mistakes.
21+
- The confusion surrounding 'use tabs to indent, spaces to justify' is gone.
22+
- Tab indents push your code to the right, making your screen seriously
23+
unbalanced.
24+
- Tabs will be rendered incorrectly on editors who are misconfigured not
25+
to use tab stops of eight positions.
26+
- Tabs are rendered badly in patches, causing off-by-one errors in almost
27+
every line.
28+
- It is the QEMU coding style.
29+
30+
Do not leave whitespace dangling off the ends of lines.
31+
32+
2. Line width
33+
34+
Lines are 80 characters; not longer.
35+
36+
Rationale:
37+
- Some people like to tile their 24" screens with a 6x4 matrix of 80x24
38+
xterms and use vi in all of them. The best way to punish them is to
39+
let them keep doing it.
40+
- Code and especially patches is much more readable if limited to a sane
41+
line length. Eighty is traditional.
42+
- It is the QEMU coding style.
43+
44+
3. Naming
45+
46+
Variables are lower_case_with_underscores; easy to type and read. Structured
47+
type names are in CamelCase; harder to type but standing out. Enum type
48+
names and function type names should also be in CamelCase. Scalar type
49+
names are lower_case_with_underscores_ending_with_a_t, like the POSIX
50+
uint64_t and family. Note that this last convention contradicts POSIX
51+
and is therefore likely to be changed.
52+
53+
When wrapping standard library functions, use the prefix qemu_ to alert
54+
readers that they are seeing a wrapped version; otherwise avoid this prefix.
55+
56+
4. Block structure
57+
58+
Every indented statement is braced; even if the block contains just one
59+
statement. The opening brace is on the line that contains the control
60+
flow statement that introduces the new block; the closing brace is on the
61+
same line as the else keyword, or on a line by itself if there is no else
62+
keyword. Example:
63+
64+
if (a == 5) {
65+
printf("a was 5.\n");
66+
} else if (a == 6) {
67+
printf("a was 6.\n");
68+
} else {
69+
printf("a was something else entirely.\n");
70+
}
71+
72+
Note that 'else if' is considered a single statement; otherwise a long if/
73+
else if/else if/.../else sequence would need an indent for every else
74+
statement.
75+
76+
An exception is the opening brace for a function; for reasons of tradition
77+
and clarity it comes on a line by itself:
78+
79+
void a_function(void)
80+
{
81+
do_something();
82+
}
83+
84+
Rationale: a consistent (except for functions...) bracing style reduces
85+
ambiguity and avoids needless churn when lines are added or removed.
86+
Furthermore, it is the QEMU coding style.
87+
88+
5. Declarations
89+
90+
Mixed declarations (interleaving statements and declarations within blocks)
91+
are not allowed; declarations should be at the beginning of blocks. In other
92+
words, the code should not generate warnings if using GCC's
93+
-Wdeclaration-after-statement option.
94+
95+
6. Conditional statements
96+
97+
When comparing a variable for (in)equality with a constant, list the
98+
constant on the right, as in:
99+
100+
if (a == 1) {
101+
/* Reads like: "If a equals 1" */
102+
do_something();
103+
}
104+
105+
Rationale: Yoda conditions (as in 'if (1 == a)') are awkward to read.
106+
Besides, good compilers already warn users when '==' is mis-typed as '=',
107+
even when the constant is on the right.
