can transform string in template expression or lambda expression in kotlin?

val tm = "x = $"+"x" val fn: (x: string) -> string = { -> tm} val str = fn("this x!!!") 

need get

x = x!!!

why?: can receive templates, example, database ps: or suggestions

kotlin templates evaluated @ compile time - won't work.

you should use 3rd party template engine.

freemarker such engine format similar kotlin's own templating format:

val tm = "x = \${x}"  fun fn (x: string) : string {     val t = template("name", stringreader(tm), configuration(configuration.version_2_3_26))     val out = stringwriter()     t.process(mapof("x" x) ,out)     return out.tostring() }  println (fn("this x!!!")) // x = x!!! 

two notes:

  • you won't able use "$x" on freemarker, "${x}"
  • $ sign can escaped in kotlin string using \$
