* ks/type-doc-cleanup/OTP-10850: Add support for printing <<_:_*1>> as bitstring() Clean up of documentation of type language
2013-02-14Add float_to_binary and binary_to_floatLukas Larsson
2013-02-14Add new binary conversion bifsLukas Larsson
Added: binary_to_integer/1,2, integer_to_binary/1,2
2013-02-11Clean up of documentation of type languageKostis Sagonas
Prompted by noticing that the type language description was a bit vague in its explanation of the syntax and semantics of bitstring types, I decided to add this information. While at it, a general clean up and rephrasing was performed. The binary() type is now described as an alias, as it should be, and a bitstring() type is also described as a built-in alias.

2013-01-25Extend char() to Unicode charactersHans Bolinder
The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.
2013-01-02[stdlib, kernel] Introduce Unicode support for Erlang source filesHans Bolinder
Expect modifications, additions and corrections. There is a kludge in file_io_server and erl_scan:continuation_location() that's not so pleasing.

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.

2011-10-13Allow noncharacter code points in unicode encoding and decodingBjörn Gustavsson
The two noncharacter code points 16#FFFE and 16#FFFF were not allowed to be encoded or decoded using the unicode module or bit syntax. That causes an inconsistency, since the noncharacters 16#FDD0 to 16#FDEF could be encoded/decoded. There is two ways to fix that inconsistency. We have chosen to allow 16#FFFE and 16#FFFF to be encoded and decoded, because the noncharacters could be useful internally within an application and it will make encoding and decoding slightly faster.

Wrote and changed some tests in stdlib:erl_lint_SUITE nowarn_bif_clash is obsoleted but will remove warnings and errors about bif clashes. The recommended way is to use no_auto_import directives instead. Hopefully erlang.erl is the only user in the world of nowarn_bif_clash.

2009-12-13Change the expected return value for on_load functionsBjörn Gustavsson
An on_load function is supposed to return 'true' to indicate that the module should be loaded, and 'false' if it should be unloaded. But returning any other term, as well as causing an exception, will also unload the module. Since we don't like boolean values mixed with other values, change the expected return value as follows: * If 'ok' is returned, the module will remain loaded and become callable. * If any other value is returned (or an exception is generated), the module will be unloaded. Also, if the returned value is not an atom, send a warning message to the error_logger (using error_logger:warning_msg/2). The new interpretation of the return value means that an on_load function can now directly return the return value from erlang:load_nif/2.
