# Powershell wrapper function to make WSL commands work with Windows path:

function WrapWSLCmd ($cmd) {
  return {
    $expr = 'wsl ' + $cmd

    for ($i=0; $i -lt $args.Count ; $i++) {
      $expr += ' '

      # Keep WSL command options:
      if ( "$( $args[$i] )".StartsWith('-') ) {
        $expr += $args[$i]
        continue
      }

      $expr += '`"`$`(' + 'wslpath -a ' + "```'" + "$( $args[$i] )" + "```'" + '`)`"'
    }

    Invoke-Expression "$expr"
  }.GetNewClosure()

#
# $function:vim      = $(WrapWSLCmd('vim'))
# $function:vimdiff  = $(WrapWSLCmd('vimdiff'))
# $function:view     = $(WrapWSLCmd('view'))
