Individual TemplateElements are not supported

[magiblot]

Hello,

The structure of TemplateLiteral is as follows:

The elements of quasis are TemplateElement nodes. When parsing TemplateLiteral nodes, astring accesses the quasis' content directly:

astring/src/astring.js

Line 686 in 21f5c2c

state.write(quasis[i].value.raw)

This is OK unless you ask astring to parse the TemplateElement node individually. In that case, astring will crash as it doesn't have a specific method for this node type.

I wonder if this was an oversight or if it is intentional. Should I just write my own generator for TemplateElement?

Thank you very much.

Thanks for reporting this. You're right, Astring should render any Estree node. Failing to do so should be considered a bug. Feel free to submit a PR.

It doesn't seem too hard, though I don't know what to do with the EXPRESSIONS_PRECEDENCE values. What should the value for TemplateElement be?

[davidbonnet]

No EXPRESSIONS_PRECEDENCE required. All there is to do is to add an extra handler called TemplateElement that does state.write(quasis[i].value.raw).
