Description

When a ConfigObject is written to file all values are quoted with ". This leads to problems if a value contains a $ for example.

Consider the following code snipet:

def config = new ConfigObject()
config.instObject = '1. Dyn. Aktber. ($IO_AKTBER)   # Aktenbereich (V-AKTBER)'

println "config before writing to file:    ${config}"

def file = new File('C:/Temp/config.groovy')
file.withWriter { writer ->
    config.writeTo(writer)
}

config = new ConfigSlurper().parse(file.getText())
println "config after reloading from file: ${config}"

The output is:

config before writing to file:    [instObject:1. Dyn. Aktber. ($IO_AKTBER)   # Aktenbereich (V-AKTBER)]
config after reloading from file: [IO_AKTBER:[:], instObject:1. Dyn. Aktber. ([:])   # Aktenbereich (V-AKTBER)]

The according file content:

instObject="1. Dyn. Aktber. ($IO_AKTBER)   # Aktenbereich (V-AKTBER)"

As can be seen the two config objects differ widely. A solution could perhaps be writing properties quoted by ' or writing the properties the way they are quoted in the source code, e. g. config.property1 = "$property1" would become property1 = "$property1" in the file and config.property2 = '$property1' would become property2 = '$property1'. This way the programmer could control the desired behaviour.
