# Scribe
Pretty-print tables of Elixir structs and maps. Inspired by [hirb](https://github.com/cldwalker/hirb).
## Installation
1. Add `scribe` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:scribe, "~> 0.10"}
]
end
```
## Usage
Print a list of maps or structs as a table. Header columns are taken from the
keys of the first element.
```elixir
iex(1)> data = [%{key: "value", another_key: 123},
...(1)> [%{key: "test", another_key: :key}]
iex(2)> Scribe.print(data)
+----------------+-------------+
| :another_key | :key |
+----------------+-------------+
| 123 | "value" |
| :key | "test" |
+----------------+-------------+
```
Useful for printing large collections, such as results of database queries
```elixir
# %User{id: nil, email: nil}
iex(1)> User |> limit(5) |> Repo.all |> Scribe.print
+-------------+----------------------------+------+
| :__struct__ | :email | :id |
+-------------+----------------------------+------+
| User | "[email protected]" | 5171 |
| User | "[email protected]" | 4528 |
| User | "[email protected]" | 1480 |
| User | "[email protected]" | 2084 |
| User | "[email protected]" | 6599 |
+-------------+----------------------------+------+
```
## Use Scribe Automatically
Scribe can override `Inspect` to automatically return maps in table format.
Add the following to your `config/dev.exs`:
```elixir
config :scribe,
compile_auto_inspect: true,
auto_inspect: true
```
Temporarily disable in the shell if needed:
```elixir
iex(1)> Scribe.auto_inspect(false)
:ok
```
**Note: Auto-inspect will not work in production Distillery
releases. Leave it out of your prod.exs**
## Pagination
Scribe uses [pane](https://github.com/codedge-llc/pane) to paginate large tables.
Use with `Scribe.console/2`.
```elixir
# %User{id: nil, email: nil, first_name: nil, last_name: nil}
iex(1)> User |> limit(5) |> Repo.all |> Scribe.console
+-------------+------------------------+-------------+-------+------------+
| :__struct__ | :email | :first_name | :id | :last_name |
+-------------+------------------------+-------------+-------+------------+
| User | "celestine_satterfield | "Gene" | 9061 | "Krajcik" |
| User | "[email protected]" | "Maeve" | 9865 | "Gerlach" |
| User | "[email protected]" | "Theodora" | 2262 | "Wunsch" |
| User | "[email protected] | "Oswaldo" | 4977 | "Simonis" |
| User | "caesar_hirthe@reynold | "Arjun" | 3907 | "Prohaska" |
+-------------+------------------------+-------------+-------+------------+
[1 of 1] (j)next (k)prev (q)quit
```
## Printing Custom Tables
`Scribe.print/2` takes a list of of columns on the `:data` options key to
customize output. You can use either the atom key or customize the header
with `{"Custom Title", :key}`.
```elixir
# %User{id: nil, email: nil, first_name: nil, last_name: nil}
User
|> limit(5)
|> Repo.all
|> Scribe.print(data: [{"ID", :id}, :first_name, :last_name])
+------+--------------+-------------+
| "ID" | :first_name | :last_name |
+------+--------------+-------------+
| 9061 | "Gene" | "Krajcik" |
| 9865 | "Maeve" | "Gerlach" |
| 2262 | "Theodora" | "Wunsch" |
| 4977 | "Oswaldo" | "Simonis" |
| 3907 | "Arjun" | "Prohaska" |
+------+--------------+-------------+
```
### Function Columns
You can specify functions that take the given row's struct or map as its only argument.
```elixir
# %User{id: nil, email: nil, first_name: nil, last_name: nil}
results =
User
|> limit(5)
|> Repo.all
|> Scribe.print(data: [{"ID", :id}, {"Full Name", fn(x) -> "#{x.last_name}, #{x.first_name}" end}])
+--------------------------+----------------------------------------------+
| "ID" | "Full Name" |
+--------------------------+----------------------------------------------+
| 9061 | "Krajcik, Gene" |
| 9865 | "Gerlach, Maeve" |
| 2262 | "Wunsch, Theodora" |
| 4977 | "Simonis, Oswaldo" |
| 3907 | "Prohaska, Arjun" |
+--------------------------+----------------------------------------------+
:ok
```
## Styling Options
### Width
Pass a `width` option to define table width.
```elixir
iex> Scribe.print(data, width: 80)
+-------------------+-----------------------------------------------------+
| :id | :key |
+-------------------+-----------------------------------------------------+
| 910 | "B1786AC67B4DEB19" |
| 313 | "30CB8A2DE4750070" |
| 25 | "D0859205FC7E7298" |
| 647 | "8F0060AD0BD6AB04" |
| 253 | "65509A684D619182" |
+-------------------+-----------------------------------------------------+
```
### Disable Colors
```elixir
iex> Scribe.print(data, colorize: false)
```
