# Render Me Pretty
[](https://www.boltops.com)
Let's say you have an error in your ERB template:
```
line 1
<%= sdsd %>
line 3
```
Normally, when render it with ERB you get an error message that looks something like this:
```sh
NameError:
undefined local variable or method `sdsd' for #
(erb):2:in `get_binding'
./lib/render_me_pretty.rb:71:in `render'
./spec/lib/render_me_pretty/erb_spec.rb:41:in `block (3 levels) in '
```
Instead, this library produces an output with an error pointing out the original line in the ERB template like so:
```
NameError evaluating ERB template on line 2 of: spec/fixtures/invalid.erb
1 line 1
2 <%= sdsd %>
3 line 3
```
The output also colorizes the error line in red so it stands out.
## Usage
Here's a simple example:
```ruby
erb = RenderMePretty::Erb.new("/path/to/tempate.erb", a: 3) }
erb.render(a: 4)
```
There's also a convenience class method:
```ruby
RenderMePretty.result("/path/to/tempate.erb", a: 5)
```
### Layout Support
```ruby
RenderMePretty.result("/path/to/tempate.erb", layout: "/path/to/layout.erb")
```
### Custom Context
```ruby
person = Person.new("tung")
erb = RenderMePretty::Erb.new("/path/to/tempate.erb", a: 3, context: person) } # passing context here
erb.render(a: 4)
person = Person.new("tung")
erb = RenderMePretty::Erb.new("/path/to/tempate.erb", a: 3) }
erb.render(person, a: 4) # passing context here
```
The context's methods and instance variables are available in the ERB template. Variables passed at initialization time to `RenderMePretty::Erb.new` or at call time for `render` be set as instance variables to a clone of the original context object.
So in the case above, if there was an `@a` instance variable in the Person object, it will not get respected. Instead the value would be `@a = 4`.
### Context
You can pass in a context object also. Examples:
A few more examples are in the [erb_spec.rb](spec/lib/render_me_pretty/erb_spec.rb)
