FirebaseLink package does not work on windows

UPDATE: 25-Jan-17 12:02AM CET

The problem could probably be reduced to: "How do I get the literal string

"{\" foo3 \":\" bar3 \"}"

from the association

<|"foo3" -> "bar3"|>


This makes the problem testable, I suppose.


I am working on a notebook where I have to execute external Windows10 commands ( i.e. write data to a Firebase database using curl ). In question How to call external commands with parameters on Win7? I found that I should use


At the DOS level I want to execute a string in this format:

curl -X PUT -d "{\"name\":{\"last\": \"sparrow\"}}" https://samplechat.firebaseio-demo.com/users/jack.json

( See also question: Firebase - How to write using curl? )

The string

"{\"name\":{\"last\": \"sparrow\"}}"

must be in JSON format recognizable by Firebase. In my application this data comes from a function which returns a list of associations.

ExportString[getBkmkCompEvntMrkt[], "JSON"]

So I have

curl -X PUT -d
ExportString[getBkmkCompEvntMrkt[], "JSON"], and

to work with.

Sofar I have consistently failed to get this working.

Please advise.

For your updated question this might work:

KeyValueMap[Colon, <|"foo3" -> "bar3"|>]
ToString[%, InputForm]
StringReplace[%, "\[Colon]" -> ":"]
{"foo3" \[Colon] "bar3"}

"{\"foo3\" \[Colon] \"bar3\"}"

"{\"foo3\" : \"bar3\"}"
  • $\begingroup$ Thanks. This question got a bit out of hand, really ( also mathematica.stackexchange.com/questions/136166/… ). - The point is that I had problems with the FirebaseLink package which is a Mac only hack. While modifying the package I came across some of the issues above. - It is all running now. $\endgroup$ Jan 26, 2017 at 18:00
  • $\begingroup$ The FirebaseLink package is not from Wolfram, it lives on Github. $\endgroup$ Jan 26, 2017 at 18:01

The question arose from using the package FirebaseLink. It turned out that this package does not work on Windows(!). I solved the issue here: Patch for FirebaseLink if you want to use the package in a windows environment.

Windows requires Run for external programs and does not allow single quotes around the firebase URL.
