# 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
(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.
