Description
Consider the following code.
# Consider the following code.
Markdown.render <<~MARKDOWN
# Hello there
This is a Markdown file. See?
1. This is a list
2. With items
3. And more items
MARKDOWN
There's a lot of "Markdown" that's repeated.
# Or this
SQL.execute <<~SQL
SELECT * FROM users WHERE id = 1;
SQL
It's fine. It works. The key feature is that it understands the text in that block is indented.
Not requiring the name could make the syntax less redundant and free developers up from having to name the string. Here's what that could look like:
# Now with 75% less markdown!
Markdown.render <<~
# Hello there
This is a Markdown file. See?
1. This is a list
2. With items
3. And more items
~>>
# We can't sell SQL symbols fast enough!
SQL.execute <<~
SELECT * FROM users WHERE id = 1;
~>>
I implement a lot of my application UI in Phlex. The dream is that I can build pages out that look like this:
class Form < ApplicationForm
def view_template
input(type: "text", name: "name", placeholder: "Name")
fieldset{
h2 { "Agreement" }
article(class: "prose"){
markdown <<~

}
}
button{ "Submit" }
end
end
The closest I can get to that today is if I do this:
SQL.execute <<~_
SELECT * FROM users WHERE id = 1;

I've proposed a similar feature a while back and chimed in on similar proposals, but after thinking about it for a bit I realized "Anonymous HEREDOC blocks" is a slightly different approach that could be a different possible path forward.
