Code conventions
================
When writing new code, please adhere to the following conventions.
White space:
- Expand tabs to 4 spaces.
- Don't leave trailing whitespace at the end of a line.
- For control blocks (if, for, while), put 1 space between the
keyword and the opening parenthesis.
- Put 1 space after a comma, and 1 space around operators.
Braces:
- Use braces for all blocks, even no-line and single-line pieces of
code.
- Put opening braces on the end of the line it belongs to, not on
a new line.
- For else-statements, put the else on the same line as the previous
closing brace.
Include directives:
- Don't include within a header file.
Type names and declarations:
- When defining a type, put '_t' after it.
Examples
--------
Braces and spaces:
int foo(int x, int y) {
if (x < y) {
foo(y, x);
} else {
foo(x + 1, y - 1);
}
for (int i = 0; i < x; i++) {
}
}
Type declarations:
typedef struct _my_struct_t {
int member;
void *data;
} my_struct_t;
