Is there an Erlang IDE?
The “official” development environment for Erlang is Emacs, and there’s a special emacs mode for Erlang. This can be found in lib/emacs/erlang.el under the source tree. VI fans have several options. There is a colouring mode for nedit. VIM has a fully-fledged Erlang mode. A basic version is included in VIM as of version 5.6, a much more complete version is available for download. There is an Eclipse plugin for Erlang. Some Windows developers use Ultraedit. Danie Schutte contributed a wordfile which provides syntax highlighting. There is an Erlang editor for NetBeans : ErlyBird There is a defunct X IDE for unix systems called “xerl”. It isn’t worth using.
