if statements highlighted as error in Nextflow .config files

[mblanche]

Hi, with the new 1.0.2 release, I'm now getting an highlighted error when using if () {} block statement in config files.

Issue:

if (params.outdir){
  process {
    withName: 'bam2bigwig' {
      publishDir = [
        [
          path: { "${params.outdir}/bigwig" },
          mode: params.publish_dir_mode,
        ]
      ]
    }

  }
}

The if is underlined in red with the error: Unexpected input: 'if'

Expected behavior:

No error

If statements are not supported in the strict config syntax: https://nextflow.io/docs/latest/vscode.html#configuration-syntax

These language server errors will eventually become errors in Nextflow
