# list_as_table

#### _Pretty print proplists in erl shell_

## Synopsis

This is a simple module to present lists of proplists in form of ascii table.

## How to install

Add in deps section of `rebar.config`

```
{deps, [
  {list_as_table, {git, "https://github.com/eiri/list_as_table.git", {tag, "0.2.0"}}}
]
```

## How to use

`last_as_table` is just a library, so just make sure it is in `--pa` path and then pass a list of proplists to it as `list_as_table:print(List)`

### Example

Lets output VM's process list as a table, simlar to erl's `i().`

```
Eshell V6.0  (abort with ^G)
(list_as_table@StarFortress)1> Keys = [registered_name,initial_call,current_function,heap_size,reductions,stack_size].
[registered_name,initial_call,current_function,heap_size,
 reductions,stack_size]
(list_as_table@StarFortress)2> F = fun(Pid, L) -> [{pid, Pid}|[{K, proplists:get_value(K, L)} || K <- Keys]] end.
#Fun<erl_eval.12.106461118>
(list_as_table@StarFortress)3> P = [F(Pid, erlang:process_info(Pid)) || Pid <- erlang:processes()].
[[{pid,<0.0.0>},
  {registered_name,init},
  {initial_call,{otp_ring0,start,2}},
... looong list ...

(list_as_table@StarFortress)4> list_as_table:print(P).

Much more readable now, isn't it?

Simple example application included in _example_ directory. Run `make run` to compile and start it, then call `tabula:demo()` in erlang shell.
