# How to use
## Including
More often, you will include the library as a dependency to your project. In order to do this, add the following lines to your **Cargo.toml** file :
```toml
[dependencies]
prettytable-rs = "0.4.0"
```
## Basic usage
You can start using it the following way :
```rust
#[macro_use] extern crate prettytable;
use prettytable::Table;
use prettytable::row::Row;
use prettytable::cell::Cell;
fn main() {
// Create the table
let mut table = Table::new();
// Add a row
table.add_row(row!["ABC", "DEFG", "HIJKLMN"]);
table.add_row(row!["foobar", "bar", "foo"]);
// Or the more complicated way :
table.add_row(Row::new(vec![
Cell::new("foobar2"),
Cell::new("bar2"),
Cell::new("foo2")])
);
table.printstd();
}
```
This code will produce the following output :
```text
+---------+------+---------+
| foobar | bar | foo |
+---------+------+---------+
| foobar2 | bar2 | foo2 |
+---------+------+---------+
```
## Using macros
To make the code simpler, the `table!` macro is there for you. The following code would produce the exact same output :
```rust
#[macro_use] extern crate prettytable;
fn main() {
let table = table!(["ABC", "DEFG", "HIJKLMN"],
["foobar", "bar", "foo"],
["foobar2", "bar2", "foo2"]
);
table.printstd();
}
```
Using the `ptable!` macro would even print it on stdout for you.
Tables also support multiline cells content. As a consequence, you can print a table into another table (yo dawg ;).
For example, the following code
```rust
let table1 = table!(["ABC", "DEFG", "HIJKLMN"],
["foobar", "bar", "foo"],
["foobar2", "bar2", "foo2"]
);
let table2 = table!(["Title 1", "Title 2"],
["This is\na multiline\ncell", "foo"],
["Yo dawg ;) You can even\nprint tables\ninto tables", table1]
);
table2.printstd();
```
Would print the following text :
```text
+-------------------------+------------------------------+
| This is | foo |
| a multiline | |
| cell | |
+-------------------------+------------------------------+
| Yo dawg ;) You can even | +---------+------+---------+ |
| print tables | | ABC | DEFG | HIJKLMN | |
| into tables | +---------+------+---------+ |
| | | foobar | bar | foo | |
| | +---------+------+---------+ |
| | | foobar2 | bar2 | foo2 | |
| | +---------+------+---------+ |
+-------------------------+------------------------------+
```
Rows may have different numbers of cells. The table will automatically adapt to the largest row by printing additional empty cells in smaller rows.
## Do it with style
Tables can be added some style like colors (background / foreground), bold, and italic, thanks to the `term` crate.
You can add `term` style attributes to cells programmatically :
```rust
extern crate term;
use term::{Attr, color};
(...)
table.add_row(Row::new(vec![
Cell::new("foobar2")
.with_style(Attr::ForegroundColor(color::GREEN))
.with_style(Attr::Bold),
Cell::new("bar2")
.with_style(Attr::ForegroundColor(color::RED)),
Cell::new("foo2")])
);
```
Or you can use the style string :
```rust
Cell::new("foo2").style_spec("FrByc")
```
Where **FrBybc** means **F**oreground: **r**ed, **B**ackground: **y**ellow, **b**old, **c**enter
With macros it's even simpler :
In rows, for each cells :
```rust
row![FrByb:"ABC", FrByb:"DEFG", "HIJKLMN"];
```
Or for the whole row :
```rust
row![FY -> "styled", "bar", "foo"];
```
In tables, for each cells :
```rust
table!([FrBybl:"A", FrBybc:"B", FrBybr:"C"], [123, 234, 345, 456]);
```
Or for each rows :
```rust
table!([Frb -> "A", "B", "C"], [Frb -> 1, 2, 3, 4], [1, 2, 3]);
```
### List of style specifiers :
* **F** : **F**oreground (must be followed by a color specifier)
* **B** : **B**ackground (must be followed by a color specifier)
* **b** : **b**old
* **i** : **i**talic
* **u** : **u**nderline
* **c** : Align **c**enter
* **l** : Align **l**eft
* **r** : Align **r**ight
* **d** : **d**efault style
### List of color specifiers :
* **r** : Red
* **b** : Blue
* **g** : Green
* **y** : Yellow
* **c** : Cyan
* **m** : Magenta
* **w** : White
* **d** : Black
Capital letters are for **bright** colors. Eg :
* **R** : Bright Red
* **B** : Bright Blue
* ... and so on ...
