1  # KNXD Coding Style
 2  
 3  KNXD is written in C++. It has originally been formatted using "indent",
 4  which unfortunately knows only C but next to nothing about C++, thus some
 5  of the spacing in the code doesn't look at all like idiomatic C++.
 6  
 7  Please try to adhere to the formatting of existing code as much as
 8  possible, or at least as much as you're comfortable with. Specifically,
 9  please adhere to the two/four-space indent scheme:
10  
11      if (x)
12        {
13          more_statements;
14          more_statements;
15        }
16      else
17        single_statement;
18  
19  ## "#ifdef"s
20  
21  All "#ifdef" statements should be either
22  
23  * guard macros (#ifndef foo / #define foo … / #endif)
24  
25  * conditional on a specific compiler (cf. "#ifdef __gnuc__" in
26    src/common/types.h)
27  
28  * conditional on "HAVE_XXX" as discovered by autoconf.
29  
30  Operating system specific conditionals are not allowed: they tend
31  to stop working when you switch compilers, cross-compile, or build
32  with an alternate libc.
