2016-01-29Eliminate redundant double is_function testBjörn Gustavsson
When tuple funs were still supported, the idiom for allowing real funs with a certain arity but not tuple funs was: is_function(Fun) andalso is_function(Fun, Arity) The reason that both tests were needed is because: is_function({M,F}) would return 'false' is_function({M,F}, Arity) would return 'true' In 53ec991d19, is_function/2 was updated to only return 'false' for tuples, so the call to is_function/1 can be removed.

2013-12-12Support named funs in the shellAnthony Ramine
The current code for the evaluation of ordinary funs is dependent on the order on variables in the fun environment as returned by erlang:fun_info(Fun, env). To avoid the problem in the future, make sure that we only have one free variable in the funs that we will need to inspect using erlang:fun_info(Fun, env).

2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.

2010-02-12Merge branch 'ks/stdlib-cleanups' into ccase/r13b04_devErlang/OTP
* ks/stdlib-cleanups: stdlib: clean up as suggested by tidier OTP-8435: ks/stdlib-cleanups
2010-02-10stdlib: clean up as suggested by tidierKostis Sagonas
Hans Bolinder (the author/maintainer of qlc) prefers for readability reasons to use length/1 in a guard when it is known that the list is guaranteed to be short, so the change suggested by tidier for line 875 of qlc_pt has not been included.
