Override default function for handling ES6 template strings (quasi-literals)

ES6 offers template strings, such as 

`Hello ${name}`

In this case a default template builder is called. You can also use your own "tags":

tag`Hello ${name}`

where tag is a function which is passed information about the template string and generates a result.

My question is, is there any way to override the default function called when no tag is specified?

Another question: Is there any way to determine if the tag function is being called by the system to construct a template string, versus say being called directly, other than examining the first argument for a raw property?

Solution

  • No. They are different syntactic productions with different semantic meanings. `stuff` is more akin to a string literal, whereas tag`stuff` is more akin to a function call.
