icon.to_svg
#
```
## Documentation
The `Octicon` class takes two arguments. The first is the symbol of the icon, and the second is a hash of arguments representing html attributes
### `symbol` _(required)_
This is the name of the octicon you want to use. For example `alert`. [Full list of icons](/)
### Options
* `:height` - When setting the height to a number, the icon will scale to that size. For example, passing `32`, will calculate the width based on the icon's natural size.
* `:width` - When setting the width to a number, the icon will scale to that size. For example, passing `32`, will calculate the width based on the icon's natural size.
If both `:width, :height` are passed into the options hash, then the icon will be sized exactly at those dimensions.
### Attributes
Once initialized, you can read a few properties from the icon.
#### `symbol`
Returns the string of the symbol name
```rb
icon = Octicons::Octicon.new("x")
icon.symbol
# "x"
```
#### `path`
Path returns the string representation of the path of the icon.
```rb
icon = Octicons::Octicon.new("x")
icon.path
#
```
#### `options`
This is a hash of all the `options` that will be added to the output tag.
```rb
icon = Octicons::Octicon.new("x")
icon.options
# {:class=>"octicon octicon-x", :viewBox=>"0 0 12 16", :version=>"1.1", :width=>12, :height=>16, :"aria-hidden"=>"true"}
```
#### `width`
Width is the icon's true width. Based on the svg view box width. _Note, this doesn't change if you scale it up with size options, it only is the natural width of the icon_
#### `height`
Height is the icon's true height. Based on the svg view box height. _Note, this doesn't change if you scale it up with size options, it only is the natural height of the icon_
#### `keywords`
Returns an array of keywords for the icon. The data comes from the [data file in lib](../data.json). Consider contributing more aliases for the icons.
```rb
icon = Octicons::Octicon.new("x")
icon.keywords
# ["remove", "close", "delete"]
```
### Methods
#### `to_svg`
Returns a string of the svg tag
```rb
icon = Octicons::Octicon.new("x")
icon.to_svg
#
```
