Next message: [erlang-questions] a surprising atom Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Well, since [] (or "") is a valid string, and list_to_atom/1 will convert a valid string to a valid atom*, it's perfectly logical that there should be an "empty atom" as well.

"hello world". 13 Jan 2017 Elixir has a wealth of data types available. The usual basic types integer, float, boolean, and string are here, but so are the atom / symbol, list, 2> F("lists:concat(['haha',B,'ok!']).",[{'B',23}]). [{atom,1,lists}, {':',1} String fields are mapped to Erlang strings unless the --erl-bin-str command line option is Optional fields either contain a value or contain the atom 'nil' . I am pretty sure that is inherited directly from Erlang, from what I remember.

If you’ve never really jumped in, Erlang may seem kinda… weird. And if you had a closer look, it may seem even weirder. Similar to s, but the resulting string is converted into an atom.

Some ten thousands atoms is perfectly normal, but more could indicate that the BIF erlang:list_to_atom/1 is used to dynamically generate a lot of different atoms, which is never a good idea. 4.2 Memory information Is this Erlang or Elixir?

Erlang - concat - The method concats 2 strings and returns the concatenated string. Bert.decode and Bert.encode use a nodejs Buffer object containing the binary erlang term, converted using the following rules : erlang atom foobar is js {type: "Atom",value: "foobar", toString->value} create it with Bert.atom("foobar") the toString() method allows you to match with string myatom == 'foobar' erlang list is js list

Thus, it is not necessary to specify the module name. For example, the calls atom_to_list(erlang) and erlang:atom_to_list(erlang) are identical. Similar to s, but the resulting string is converted into an atom. c The number of characters equal to the field width are read (default is 1) and returned as an Erlang string. Identifier = lists: flatten (io_lib: format ( "~s:~s()", [Mod, Name])), Len = max ( 40, string: len (Identifier)), % That weird syntax is similar to a C format string, but % in erlang's own weird way. 2021-04-11 · 3.12 String. Strings are enclosed in double quotes ("), but is not a data type in Erlang.
