# Newlines styleguide
This style guide recommends best practices for newlines in Ruby code.
## Rule: separate code with newlines only to group together related logic
```ruby
# bad
def method
issue = Issue.new
issue.save
render json: issue
end
```
```ruby
# good
def method
issue = Issue.new
issue.save
render json: issue
end
```
## Rule: separate code and block with newlines
### Newline before block
```ruby
# bad
def method
issue = Issue.new
if issue.save
render json: issue
end
end
```
```ruby
# good
def method
issue = Issue.new
if issue.save
render json: issue
end
end
```
## Newline after block
```ruby
# bad
def method
if issue.save
issue.send_email
end
render json: issue
end
```
```ruby
# good
def method
if issue.save
issue.send_email
end
render json: issue
end
```
### Exception: no need for newline when code block starts or ends right inside another code block
```ruby
# bad
def method
if issue
if issue.valid?
issue.save
end
end
end
```
```ruby
# good
def method
if issue
if issue.valid?
issue.save
end
end
end
```
