2014-05-09Fix reverting map in syntax_toolsRoland Karlsson
There was a copy-paste bug in erl_syntax when running e.g. erl_syntax:revert_forms, affecting maps. Instead of getting Key/Value you got Key/Key in the resulting abstract form.

A named fun's name is a variable name, its type in syntax_tools is named_fun_expr.

2014-01-21Fix reverting of local implicit funs in erl_syntaxAnthony Ramine
This partially reverts 290dc2b08a2f92157ac5358fba815f4dbb32f8f2 in which implicit funs were mistakenly thought to be using abstract terms for their name and arity.
2013-12-12EEP 37: Funs with namesAnthony Ramine
This adds optional names to fun expressions. A named fun expression is parsed as a tuple `{named_fun,Loc,Name,Clauses}` in erl_parse. If a fun expression has a name, it must be present and be the same in every of its clauses. The function name shadows the environment of the expression shadowing the environment and it is shadowed by the environment of the clauses' arguments. An unused function name triggers a warning unless it is prefixed by _, just as every variable. Variable _ is allowed as a function name. It is not an error to put a named function in a record field default value. When transforming to Core Erlang, the named fun Fun is changed into the following expression: letrec 'Fun'/Arity = fun (Args) -> let <Fun> = 'Fun'/Arity in Case in 'Fun'/Arity where Args is the list of arguments of 'Fun'/Arity and Case the Core Erlang expression corresponding to the clauses of Fun. This transformation allows us to entirely skip any k_var to k_local transformation in the fun's clauses bodies.

Implicit funs parts in plain AST are no longer in concrete form since Erlang/OTP R15.
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.

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.

2010-10-26syntax_tools: Fix an erroneous type and strengthen some specsKostis Sagonas
The declaration of the stubDescriptop() type in 'igor' was erroneous, both in the -type and in the published documentation of the module. While fixing this some specs where strengthened and used a remote type to refer to ordsets:ordset(T). Consequently, this patch depends on the ordsets module exporting the ordset/1 type.
