How to inject quasi quotes array - scala

Question

I have an array of quasi quotes called definitions which I want to inject to the quasi quote tree. How do I go about doing this?
private def generateDaoComponent(files: Array[File]) = {
val file = createNewFile(compDirectory)
val definitions = files.map(f => {
val daoName = f.getName.replace(".java", "")
val daoType = TypeName(daoName)
val daoTerm = TermName(daoName)
q"""def $daoTerm = getValueOrInstantiate($daoName, () => new $daoType(configuration))
"""
})
val tree = q"""
package database.dao {
import org.jooq.SQLDialect
import org.jooq.impl.DefaultConfiguration
import utility.StrongHashMap
trait $componentType extends StrongHashMap[String, Dao] {
this: DaoManager =>
private lazy val configuration = new DefaultConfiguration().set(connection).set(SQLDialect.POSTGRES_9_4)
${definitions.foreach(f => q"${f}")}
}
}"""
writeToFile(file, tree)
}

This is some crazy late night coding, but I found it thanks to this website
3 approaches to Scala code generation
I noticed when it passed the $params array into the quasi quote it used two .. in front of the class constructor like this:
val params = schema.fields.map { field =>
val fieldName = newTermName(field.name)
val fieldType = newTypeName(field.valueType.fullName)
q"val $fieldName: $fieldType"
}
val json = TypeSchema.toJson(schema)
// rewrite the class definition
c.Expr(
q"""
case class $className(..$params) {
def schema = ${json}
}
"""
)
There are two steps to the code I posted in the question to make this working.
1) Convert $definitions.toList to List
2) Add the two .. in front
So the final code looks like this:
val definitions = files.map(f => {
val daoName = f.getName.replace(".java", "")
val daoType = TypeName(daoName)
val daoTerm = TermName(new StringBuilder("get").append(daoName).toString())
q"""def $daoTerm = getValueOrInstantiate($daoName, () => new $daoType(configuration))"""
}).toList <--- HERE!
val tree = q"""
package database.dao {
import org.jooq.SQLDialect
import org.jooq.impl.DefaultConfiguration
import utility.StrongHashMap
trait $componentType extends StrongHashMap[String, Dao] {
this: DaoManager =>
private lazy val configuration = new DefaultConfiguration().set(connection).set(SQLDialect.POSTGRES_9_4)
..$definitions <-- AND HERE!
}
