What is wrong with this "else if" statement?

[olgabot]

Hello, I'm trying to write a workflow that executes the following logic:

1. If method == "minhash", run sourmash.CompareFastqs
2. Else If molecule == "protein" --> fail because only sourmash supports "protein"
3. Else If method == "hyperloglog", run dashing.CompareFastqs with distance := "dist"
4. Else If method == "truejaccard", run dashing.CompareFastqs with distance := "truejaccard"
5. Fail because the method and molecule are not supported.

Constructing this conditional has been tricky so far. Here's the relevant code snippet:

val matrix = if method == "minhash" {
  sourmash.CompareFastqs(reads, names, molecule, log2_sketch_size, ksize, threads)
  } else if molecule == "protein" {
      panic("Molecule 'protein' is currently only supported by 'minhash' "+
        "method, not 'hyperloglog' or 'truejaccard'")
  } else if method == "hyperloglog" {
    distance := "dist"
    dashing.CompareFastqs(reads, names, log2_sketch_size, ksize, threads, distance)
  } else if method == "truejaccard" {
    distance := "setdist"
    dashing.CompareFastqs(reads, names, log2_sketch_size, ksize, threads, distance)
  } else {
    panic("Method '" + method + "' is not currenly supported. Please "+ 
      "use either 'minhash', 'hyperloglog', or 'truejaccard'")
  }

And here's the error:

(base)
 ✘  Mon 25 Feb - 12:05  ~/code/kmer-hashing/reflow   origin ☊ olgabot/dashing ↑2 15☀ 1● 
  reflow doc compare_fastqs.rf
compare_fastqs.rf:60:12: syntax error: unexpected tokIf, expecting '{'

(this is the } else if molecule == "protein" { line)

Can you spot the error? It seems like it should be really simple but my eyes just don't catch it.

Warmest, Olga

We did not make a new github release after adding else if. reflow0.6.8 was made in August. Let me get that going.
