# Summary
Hi. Current `heredoc` injection for Ruby language captures the
`heredoc_end` token. That's a bit incorrect because we want to capture
the content only. Suppose we have the following Ruby code:
```ruby
<<~JS
function myFunc() {
const myConstant = [];
}
let a = '1'
JS
```
And this is its syntax tree:
```
[program] [0, 0] - [7, 0]
[heredoc_beginning] [0, 0] - [0, 5]
[heredoc_body] [0, 5] - [6, 2]
[heredoc_content] [0, 5] - [6, 0]
[heredoc_end] [6, 0] - [6, 2]
```
Current injection capture all content of the `heredoc_body`:
But we want to capture the `heredoc_content` only and this PR resolves
that, additionally it downcases the language like Zed does in other
languages like Terraform.
