# Single And Double Quoted String Notation
|
|
|
|
If you are building a string that involves interpolation and literal double
|
|
quotes, then you'll have to do some escaping. Here is an example:
|
|
|
|
```ruby
|
|
> feet, inches = [6, 4]
|
|
> puts "I am #{feet}'#{inches}\" tall"
|
|
I am 6'4" tall
|
|
```
|
|
|
|
Having to escape a single instance of a double quote isn't so bad. If you find
|
|
yourself having to do it a bunch, Ruby has something for you. It is a string
|
|
syntax feature called [Percent Notation](percent-notation.md).
|
|
|
|
You can use percent notation to define double-quoted strings using `Q`:
|
|
|
|
```ruby
|
|
> puts %Q[I am #{feet}'#{inches}" tall]
|
|
I am 6'4" tall
|
|
```
|
|
|
|
No need to escape the double quote here.
|
|
|
|
There is a single-quoted version as well using `q`:
|
|
|
|
```ruby
|
|
> puts %q[I am #{feet}'#{inches}\" tall]
|
|
I am #{feet}'#{inches}\" tall
|
|
```
|
|
|
|
This is notably less useful than `%Q`. For that reason, `%Q` makes sense as a
|
|
default and it makes up the percent notations unmodified behavior:
|
|
|
|
```ruby
|
|
> puts %[I am #{feet}'#{inches}" tall]
|
|
I am 6'4" tall
|
|
```
