Java and Kotlin lambdas break the parser

Hey, it’s me again 👋

I’m having an issue which breaks the code generator similarly to https://github.com/casid/jte/issues/112.

This time it’s happening with Java and Kotlin lambdas. Examples:

Lambdas.jte

!{var name = java.util.Optional.<String>ofNullable(null)}
${name.map((n) -> { "name: " + n }).orElse("")}

Which produces:

public static void render(gg.jte.TemplateOutput jteOutput, gg.jte.html.HtmlInterceptor jteHtmlInterceptor) {
	var name = java.util.Optional.<String>ofNullable(null);
	jteOutput.writeContent("\n");
	jteOutput.writeUserContent(name.map((n) -> { "name: " + n );
	jteOutput.writeContent(").orElse(\"\")}\n");
}

While this:

Lambdas.kte

!{val name: String = null}
${name?.let { "name: $it" } ?: ""}

Produces:

@JvmStatic fun render(jteOutput:gg.jte.TemplateOutput, jteHtmlInterceptor:gg.jte.html.HtmlInterceptor?) {
	val name: String? = null
	jteOutput.writeContent("\n")
	jteOutput.writeUserContent(name?.let { "name: $it" )
	jteOutput.writeContent(" ?: \"\"}\n")
}

Looks like the parser is accepting the first } character as closing the ${} block.

Thanks!

Ahh, right. Forgot you’re generating Kotlin code. In this case you’re using ContentType.Plain anyways and there’s no output escaping. Thanks for clarifying!

I’ll try to release a new version this weekend.
