Nice work!
Please write a short article into wiki (or copy from readme): http://nsis.sourceforge.net/NsJSON_plug-in

very nice, especially since none of the xml plugins worked to my satisfaction and i got the option to use json files for the same purpose. thanks stu!

[Brummelchen]

can i use it to parse json backup files from firefox (bookmark backup file/places)?

[Afrow UK]

If it is valid JSON then yes.

New version:

1.0.0.1 - 1st July 2012
* Fixed parsing of single digit numbers.
* Fixed Serialize not writing the output file when the stack isn't empty.

I've tested this version on Chrome's Preferences JSON file.

New version:

1.0.0.2 - 15th August 2012
* Fixed Unicode build parsing and serializing.

Note the Unicode build still expects ASCII encoded JSON files at the moment. I will perhaps add support for UTF-8 encoded JSON in the future.

Hey Stu, is it possible to parse floating numbers with comma instead of point?
Some currencies use it: "1.23" is "1,23"

[Afrow UK]

You have to wrap the value in quotes so that it will be treated as a string rather than a float. It is not possible any other way as a comma is used as the delimiter between objects and values (whitespace is ignored).

New version (with a fair number of changes):

1.0.1.0 - 28th August 2012
* Added /unicode switch to the Serialize function. Output files for both plug-in builds are now encoded in ANSI by default.
* Removed the Parse function in favour of Set /file [/unicode].
* Added /type, /key, /exists, /count, /isempty to the Get function.
* Added /index switch for referencing nodes by index.

Awesome plugin Stu. Any chance of extending it to support multiple json instances open at once?

[Afrow UK]

That is already supported kind of. You just need to use Set /file with a node path to load a JSON file into. The only thing you cannot do is serialize a specific node to a file, which is where a change would be necessary. How much do you need multiple instance support (give an example of usage)?

I'm using in-memory json to store lots of my own user-specific data rather than tons of global variables.
Then I want to open up a program's settings file which is also in json, add a value and resave that settings.json.

It's also useful to separate different blocks of data and only serialize the parts I need during debug.

I guess the only thing that's really needed is the ability to serialize a specific node.

Unless I can find a better solution for my in-memory storage... Actually, thinking about it I could probably use your arrays plugin and do arrays of pointers to arrays using a counter or concatenating names like
CarPark0 = array of license plates (e.g. 0=ABC123, 1=DEF456, 2=GHI789)
CarPark0_ABC123 = array of that particular car's properties (e.g. Make=ShinyThingsInc, Color=Green)

So yeah, it probably isn't necessary to have the json plugin handle more than 1 root json object at a time. I'll just write my own serializer for the arrays.

Cheers again for your awesome stuff.

I am getting truncated string values when they have spaces:

nsJSON::Set `more_stuff` `PSCHED_009_NAME` /value `QoS Packet Scheduler`

Results in:

"more_stuff": { "PSCHED_009_NAME": QoS }

[Afrow UK]

Values are parsed as JSON. If you want quoted strings you must use double quotes around the value:

nsJSON::Set `more_stuff` `PSCHED_009_NAME` /value `"QoS Packet Scheduler"`
