Q: How can I get the text values of a node?

[droslean]

In https://pkg.go.dev/github.com/yuin/[email protected]/ast#Node

type Node interface {
...
// Text returns text values of this node.
Text(source []byte) []byte
...

However, it is unclear what the source bytes are.

@yuin Any insights?

So it turns out that the source is the actual bytes that we passed to parser. It is unclear to me why we need to pass them again.

@droslean hey thanks for the explanation. I had another question hoping you could help; can you please elaborate how some nodes have Lines func defined on them but some dont? How do I tell which node kinds have Lines and which ones dont?

Also whats the difference between Text Block, and Paragraph? Similary Text vs String? I went through the docs but didnt find anything helpful there.

Thanks in advance 🙏🏾
