Lisp Flavored Erlang (LFE) is a functional, concurrent, garbage collected, general-purpose programming language and Lisp dialect built on Core Erlang and the Erlang virtual machine ().LFE builds on Erlang to provide a Lisp syntax for writing distributed, fault-tolerant, soft real-time, non-stop applications.LFE also extends Erlang to support metaprogramming with Lisp macros and an improved
io:format(F, FormatString, Args) % write to open file; io_lib:format(FormatString, Args) % return an iolist; Common control sequences in format strings. While there are many different control sequences for io:format and io_lib:format, most of the time you'll use only three different ones: ~s, ~p and ~w. ~s. The ~s is for strings.

Output − When we run the above program, we will get the following result. Example1 Let us now discuss some other methods available for file operations − file:write_file (Filename, IO) is the simplest function for writing a file at once.

Conversely, the return value of io_lib:format that you see as "\"test\". " is simply the erlang shell's representation of the same string, with the quotes and newline escaped, and surrounded by its own quotes. 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. The asterisk signifies that % we read the length of the string from the argument list, % instead of specifying it directly -record(person, { name, age, status = single }). run() -> P1 = #person{name="Joe Doe", age="25"}, io:format("Created person ~p~n", [P1#person.name]), io:format("Record fields: ~p~n", [record_info(fields, person)]), io:format("Record size: ~p~n", [record_info(size, person)]).

pi ]) "Pi is approximately given by: 3.142 " The function call io:format ("~s!~n", ["Hello"]). includes the token ~s, which accepts strings and bitstrings as arguments, and ~n. The final output message would thus be "Hello! ". Another widely used token is ~p, which will print an Erlang term in a nice way (adding in indentation and everything). The functions in the io module cannot be used, as they can only talk to an Erlang process. Instead, use functions read/2 , read_line/1 , and write/2 .
