Groovy check () handle dollar sign ($)

below code cannot work

def map = [name:"Test :: ( %2f %25 \$ * & ! @ # ^)"] String s = map.inspect() println Eval.me(s)

get error:

 Script1.groovy: 1: illegal string body character after dollar sign; solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 1, column 30. ["name":"Test :: ( %2f %25 $ * & ! @ # ^)"]

but if the line contains other special char like \ ", it works correctly. in any way how to walk around, this is crashing for me

(In response to the foregoing)

OK, if you just want to exchange information, then you should use a data exchange format such as XML or JSON. I recommend JSON because it is lightweight, fast and very easy to use:

Computer 1

 def map = [name:"Test :: ( %2f %25 \$ * & ! @ # ^)"] def json = new groovy.json.JsonBuilder() json(map) println json.toString()

Computer 2

 def incoming = '{"name":"Test :: ( %2f %25 $ * & ! @ # ^)"}' def jsonInput = new groovy.json.JsonSlurper() def map = jsonInput.parseText(incoming) println map

Please note that they require Groovy 1.8.0 or later. There are many examples for older versions of Groovy, and Grails also has its own parsers.

Use single quotes around your string:

 def map = [name:'Test :: ( %2f %25 \$ * & ! @ # ^)']

When you use double quotes, dollar char is used for patterns

Use single quotes and double backslashes, e.g.

 def map = [name:'Test :: ( %2f %25 \\$ * & ! @ # ^)'] String s = map.inspect() println Eval.me(s)

I just tested the following and it worked for me

 > a = ["guy":"mogr \$ abi"] Eval.me(a.inspect())["guy"] mogr $a bi
