Subject [GitHub] brooklyn-server issue #554: Ensured the \n character is escaped when escapin...

Github user Graeme-Miller commented on the issue:
    @aledsage has pointed out a way to get around the problem I am having, so I no longer
need this PR. However, I think it might still be useful
    @neykov, the use case here is that I have brooklyn.config like this:
      brooklyn.cfg.additions: | = test_ident = test_key
    Brooklyn sets the config to be 
    ``` = test_ident\
= test_key
    (please note '\n' is a character, not a '\\' followed by an 'n'. If you use a '\\' followed
by an 'n' this works)
    I later pump this config into a bash env variable like this:
      BROOKLYN_CFG_ADDITIONS: $brooklyn:config("brooklyn.cfg.additions")
    However, when the string is bash encoded, the '\n' is not encoded. My script then ends
up looking like this:
    BROOKLYN_CFG_ADDITIONS=" = test_ident = test_key"
    Which means the \n is used to create a line break in the script (which does nothing) rather
than keeping the \n in the variable.
    Changing this bash encoding means my script ends up looking like this:
    BROOKLYN_CFG_ADDITIONS=" = test_ident\
= test_key"
    Whilst Aleds suggestion will work, I worry others might try to use multi line bash config
in the same way that I did.
