+Mana Hacking Guide
+----------------------------
+
+This guide is also available at http://gitorious.org/mana/pages/Hacking
+including more tips about C++ programming in general.
+
+With multiple coders working on the same source files, there needs to be a
+standard specifying how code is written down. Not doing so can cause quite some
+annoyance for certain coders and easily creates more version conflicts than
+necessary.
+
+* Indentation:
+ Code is indented using 4 spaces, no tabs.
+
+* Line length:
+ Should not exceed 79 characters.
+
+ One reason for this is to keep code readable. In such cases it would often be
+ better to spread the line over multiple lines or use some extra temporary
+ variables. Another reason is that some of us are using editors that default
+ to an 80 character wide screen, and often put two instances next to
+ eachother. 79 character wide lines leave just a spot for the cursor at the
+ end of the line.
+
+* Control constructs like this:
+
+ Good:
+
+ if (condition)
+ {
+ }
+ else
+ {
+ }
+
+ for (init; condition; step)
+ {
+ }
+
+ while (condition)
+ {
+ }
+
+ /**
+ * Documentation about behaviour
+ * ...
+ *
+ * @param param1 the first argument
+ * @param param2 the second argument
+ */
+ void function(param1, param2)
+ {
+ }
+
+ class TheClass : public TheSubclass
+ {
+ };
+
+ When there is only one statement you may leave out the braces, but don't
+ place the statement on the same line as the condition:
+
+ Good:
+
+ if (condition)
+ statement;
+
+ Bad:
+
+ if (condition) statement;
+
+* Includes:
+ Source files should include their header first, to make sure the headers are
+ self-contained. After that follow other project includes, grouped by
+ directory and alphabetically ordered. System includes come last. All project
+ includes are done relative from the 'src' directory.
+
+ Good (subdirectory/source.cpp):
+
+ #include "subdirectory/header.h"
+
+ #include "somesub/bar.h"
+ #include "somesub/zaro.h"
+
+ #include <systemlib.h>
+
+* Comments:
+ Single line C++ style comments are indented the same as the previous line.
+
+ Good:
+ // comment
+
+ Multiple line C style comments are initially indented like previous line
+ except every new line of the comment begins with a asterisk ('*') which lines
+ up with the initial asterisk of the comment opening (1 space indent). The
+ comment is closed also with the asterisk lining up. Comment text is only
+ placed on a line starting with a asterisk.
+
+ Good:
+ /*
+ * Some comment
+ * additional comment material
+ */
+
+ Bad:
+ /* text
+ comment
+ */
+
+ Note that for documenting functions, methods and other things that can use
+ documentation, you should use Doxygen style as in the function example above.
+ For details see the manual at http://www.doxygen.org/.
+
+* Whitespace examples:
+
+ Good:
+ x = ((5 + 4) * 3) / 1.5;
+ afunction(12, 3, (1 + 1));
+
+ Bad:
+ x = ( ( 5 + 4 ) * 3 ) / 1.5;
+ afunction(12,3,(1+1));
+
+* Method, class, member and constant naming is based on the
+ generally accepted way Java code is written.
+
+ Class: CapitalizedWords
+ Method: camelCase
+ Member: mCamelCase
+ Constant/enum: UPPERCASE_UNDERSCORES
+
+ To denote global variables and functions the lowercase_underscores style may
+ be used. Hungarian style should be avoided.
+
+* Whenever you add a new source file somewhere in ./src do not forget to add
+ them in ./src/Makefile.am as well!
