Bootstraping: ============= Some files in SPOT's source tree are generated. They are distributed so that users do not need to tools to rebuild them, but we don't keep all of them under CVS because it can generate lots of changes or conflicts. Here are the tools you need to bootstrap the CVS tree, or more generally if you plan to regenerate some of the generated files. GNU Autoconf 2.57 GNU Automake 1.7.3 GNU Flex (the version probably doesn't matter much, we used 2.5.4) The CVS version of GNU Bison (called 1.875b at the time of writing) Bootstrap the CVS tree by running autoreconf -vfi and then go on with the usual ./configure make Coding conventions: =================== Here are the conventions we follow in Spot, so that the code looks homogeneous. Comments -------- * The language to use is American. * When comments are sentences, they should start with a capital and end with a dot. Dots that end sentences should be followed by two spaces (i.e., American typing convention), like in this paragraph. Formating --------- * Braces on their own line. * Text within braces is two-space indented. { f(12); } * Anything after a control statement is two-space indented. This includes braces. if (test) { f(123); while (test2) g(456); } * Braces from function/structure/enum/classe/namespace definitions are not indented. class foo { public: Foo(); protected: static int get_mumble(); }; * The above corresponds to the `gnu' indentation style under Emacs. * Put return types or linkage specifiers on their own line in function/method _definitions_ : static int Foo::get_mumble() { return 2; } This makes it easier to grep functions in the code. Function/method declarations can be put on one line. * Space before parentheses in control statements if (test) { do { something(); } while (0); } * No space before parentheses in function calls. (`some()->foo()->bar()' is far more readable than `some ()->foo ()->bar ()' is) * No space after opening or before closing parentheses, however put a space after commas (as in english). func(arg1, arg2, arg3); * No useless parentheses in return statements. return 2; (not `return (2);') * Spaces around infix binary or ternary operators: 2 + 2; a = b; a <<= (3 + 5) * 3 + f(67 + (really ? 45 : 0)); * No space after prefix unary operators, or befor postfix unary operators: if (!test && y++ != 0) { ++x; } * When an expression spans over several lines, split it before operators. If it's inside a parenthesis, the following lines should be 1-indented w.r.t. the opening parenthesis. if (foo_this_is_long && bar > win(x, y, z) && !remaining_condition) { ... } * If a line takes more than 80 columns, split it or rethink it. Naming ====== * Functions, methods, types, classes, etc. are named with lowercase letters, using an underscore to separate words. int compute_this_and_that(); class this_is_a_class; typedef int int_array[]; That is the style used in STL. * private members end with an underscore. class my_class { public: ... int get_val() const; private: int name_; }; * Identifiers (even internal) starting with `_' are best avoided to limit clashes with system definitions. * Template arguments use capitalized name, with joined words. template class foo { ... }; * Enum mumblers also use capitalized name, with joined words. * C Macros are all uppercase. * Pointers and references are part of the type, and should be put near the type, not near the variable. int* p; // not `int *p;' list& l; // not `list &l;' void* magic(); // not `void *magic();' * Do not declare many variables on one line. Use int* p; int* q; instead of int *p, *q; The former declarations also allow you to describe each variable. * The include guard for src/somedir/foo.hh is SPOT_SOMEDIR_FOO_HH
