Is there a way in a detekt spec (for a rule I'm working on) to use

${...}

in the compiled test code? If I do:

val code = """
    fun foo() {
        println("The list is ${listOf(1, 2, 3)}"
    }
""".trimIndent()
assertThat(subject.compileAndLintWithContext(wrapper.env, code)).hasSize(0)

then the compiled

ktFile

has the list expanded, but if I do:

val code = """
    fun foo() {
        println("The list is \$\{listOf(1, 2, 3)\}"
    }
""".trimIndent()
assertThat(subject.compileAndLintWithContext(wrapper.env, code)).hasSize(0)

then the compiled

ktFile

maintains the escape characters, so the code isn't actually doing the expansion

Nice to hear that you are working on a detekt rule. 🙂 The mentioned problem actually relates to the Kotlin multi-line string behavior. This has nothing to do with the

compileAndLint

functionality.

Yeah, I was wondering if perhaps a case like this had been hit before and

compileAndLint

(or some other helper function) existed to work around it in detekt

Nope there isn't, sorry. Please submit a PR, if you develop a helper function for that case.

Ok, thanks for clarifying

We might need test files containing the code to test interpolation code.

Is there a way to do that currently? i.e. if I put a

.kt

file in resources or something, is there a form of

compileAndLintWithContext

that takes in a file?

have you tried

${'$'}

instead of an escape?

val code = """
    fun foo() {
        println("The list is ${'$'}{listOf(1, 2, 3)}"
    }
	""".trimIndent()

I haven't, but looks like that did it! Thanks @Czar!

Thanks for sharing this!

You're welcome, funny thing is someone was just asking how to escape

$

without resorting to

${'$'}

several messages above 😄
