1:   Pike 8: Changes since Pike 7.8 (scratch area for future release notes)   ---------------------------------------------------------------------- + -- New language features    - ___ TOTALLY UNORGANIZED AND TOO SHORT CHANGELOG FOLOWS __ - o decode_value now throws the error object Error.DecodeError. Useful -  to catch format errors in the decode string. + o local:: + o variant +  | class Test1 { int b(); } +  | class Test2 { int a(); } +  | +  | class Foo +  | { +  | variant string foo( object q ){ return "Genericfoo"; } +  | variant string foo( Test1 x ) { return "Test 1"; } +  | variant string foo( Test2 x ) { return "Test 2"; } +  | +  | variant string bar( int(0..0) s ) { return "0"; } +  | variant float bar( int(1..1) s ) { return 1.0; } +  | variant int bar( int(2..2) s ) { return 2; } +  | } +  + o New typechecker +  + o Support for ", ##__VA_ARGS__" cpp feature. +  + o Allow '.' to be used as an index operator in the few places id did +  not work before. +  + o safe index +  + X[?10] -- index X with 10, or if X is null, evaulates to 0. +  + X?->foo -- index X with foo, or if X is null, evaluates to 0. +  + o Added the '?:' operator for compatibility with other C-like languages. +  It is identical to '||' in pike. +  + o && changed, when doing A && B, and A is false, keep A instead of +  pushing 0. +  + o X::this +  + o dynamic macros (master()->add_predefine("MACRO()", callback) etc) +  | > master()->add_predefine("RND()", lambda( string arg1 ) { return random((int)arg1); }); +  | > RND(10); +  | (2) Result: 9 +  | > cpp("RND(123)") +  | (3) Result: "19" +  | +  | It can also be used to override the default builtin macros.
