Arbetet med trådlösa sensornätverk är ett ungt område där svenska forskare i Det lilla formatet innebär att elektroderna ska kunna användas av personer i involved in the development of the Mozart and Erlang programming systems.

this actually causes the shell to emit ansi/vt control codes, where the user's terminal may or may not choose to respond. that's why scrolling "fixes" it, is that erlang has no idea that happened, and is faithfully repainting.

Sep 29, 2014 We use io:format() function for the formatted output to the terminal. Here we used pattern matching in the function argument list. This allowed us to

Module names, application names, and node names are still restricted to the ISO Latin-1 range.

The ~n adds a new line to our output.

Erlang进程不是孤立的,进程都属于进程组,进程组都有group leader.所有的进程组的IO都会重定向到group leader.当一个进程被创建的时候,它就会继承父进程的group leader.系统初始化的时候，init是它自己和其它所有进程的group leader.我们下面在Erlang Shell中做一下检验:

Module names, application names, and node names are still restricted to the ISO Latin-1 range. %% Print out a formatted string containing a string like "module:func()" %% but padded to a minimum or 40 chars. show_name (Mod, Name) - > I dentifier = 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.
