2013-05-28Support callback attributes in erl_ppAnthony Ramine
2013-05-16[stdlib] Fix pretty printing of invalid formsHans Bolinder
Thanks to Tomáš Janoušek.
2013-02-18Fix some Unicode issuesHans Bolinder
Also let the Erlang shell use the new function io:printable_range().
2013-02-15[stdlib] Correct handling of Unicode filenamesHans Bolinder
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.
2013-01-16Remove support for the query keyword and query expressionsLoïc Hoguin
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.

2011-03-22Fix a bug concerning record field typesHans Bolinder
The default value 'undefined' was added to records field types in such a way that the result was not always a well-formed type. This bug has been fixed. --- erl_pp has since OTP-8150 formatted types so that 'undefined' was removed from union types assigned to record fields. Since one cannot distinguish between 'undefined' added by the parser or supplied by the user, a side effect was that user supplied 'undefined's were also removed. Now the pretty printer shows 'undefined' even if added by the parser. This is a minor issue.
2010-06-02OTP-8664 Erlang parser augmented with operators for integer typesHans Bolinder
Expressions evaluating to integers can now be used in types and function specifications where hitherto only integers were allowed ("Erlang_Integer").
2010-03-09OTP-8501 stdlib: erl_pp no longer quotes atoms in typesHans Bolinder
The erlang pretty printer (erl_pp) no longer quotes atoms in types.
2010-03-02OTP-8473 stdlib: erl_pp bugfix abstract type 'fun'Hans Bolinder
The abstract type 'fun' could not be printed. This bug has been fixed.
