Erlang tab completion

Why

When you are working on the shell chances are you are looking to be fast. A way to be faster is to leverage the EShell’s tab completion.

Assumptions

Readers are assumed to be comfortable using the EShell to run Erlang code interactively. This feature this guide describes only works with Zotonic modules only from zotonic debug. With the zotonic shell command, the Zotonic modules need to be explicitly loaded to work with tab-completion.

How

The Erlang shell has tab-completion. IIt is very handy for using in Zotonic, especially because of Zotonic’s naming scheme. Just type:

1> z_<tab>

And you get a list of zotonic library modules. Type:

2> mod_<tab>, type m_<tab> a list of models.

You get the idea. The really nice thing is that it works for function names too.
