erl_types typesets mandatory keys with :=, and uses "..." as a shorthand for "any() => any()". Add these to erl_parse so that all representable types can be written in type-specs.

Also move check of non-atom states in callback mode state_functions to where the state function is called. This gives homogenous diagnostics for state functions, code_change/4 and system_replace_state StateFun. Irregularities pointed out by James Fish.

2016-03-01Generalize bit string comprehensionsBjörn Gustavsson
The expression in a bit string comprehension is limited to a literal bit string expression. That is, the following code is legal: << <<X>> || X <- List >> but not this code: << foo(X) || X <- List >> The limitation is annoying. For one thing, tools that transform the abstract format must be careful not to produce code such as: << begin %% Some instrumentation code. <<X>> end || X <- List >> One reason for the limitation could be that we'll get reduce/reduce conflicts if we try to allow an arbitrary expression in a bit string comprehension: binary_comprehension -> '<<' expr '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. Unfortunately, there does not seem to be an easy way to work around that problem. The best we can do is to allow 'expr_max' expressions (as in the binary syntax): binary_comprehension -> '<<' expr_max '||' lc_exprs '>>' : {bc,?anno('$1'),'$2','$4'}. That will work, but functions calls must be enclosed in parentheses: << (foo(X)) || X <- List >>

2016-02-17Implement ?FUNCTION_NAME and ?FUNCTION_ARITY macrosBjörn Gustavsson
For a long time, users have asked for one or more macros that would return the name and arity of the current function. We could define a single ?FUNCTION macro that would return a {Name,Arity} tuple. However, to access just the name or just the arity for the function, element/2 must be used. That would limit its usefulness, because element/2 is not allowed in all contexts. Therefore, it seems that we will need two macros. ?FUNCTION_NAME that expands to the name of the current function and ?FUNCTION_ARITY that expands to arity of the current function. Converting the function name to a string can be done like this: f() -> atom_to_list(?FUNCTION_NAME) ++ "/" ++ integer_to_list(?FUNCTION_ARITY). f/0 will return "f/0". The BEAM compiler will evaluate the entire expression at compile-time, so there will not be any run-time penalty for the function calls. The implementation is non-trivial because the preprocessor is run before the parser. One way to implement the macros would be to replace them with some placeholder and then let the parser or possibly a later pass replace the placeholder with correct value. That could potentially slow down the compiler and cause incompatibilities for parse transforms. Another way is to let the preprocessor do the whole job. That means that the preprocessor will have to scan the function head to find out the name and arity. The scanning of the function head can be delayed until the first occurrence of a ?FUNCTION_NAME or ?FUNCTION_ARITY. I have chosen the second way because it seems less likely to cause weird compatibility problems.

2015-12-15doc: Remove 'is_subtype' from Types and Function SpecificationsHans Bolinder
It is harder to remove is_subtype from the parser since the abstract format does not separate is_subtype from the '::' syntax.

- at appending when allocating new binary object its size will be double (the old size + size of data to be appended) not just double the old size - correct some unused byte counts
