Hi,

When do you plan to integrate loadJSON function as it is proposed in the wiki ?

http://wiki.plantuml.net/site/preprocessing-json

Thanks

Good morning!

I implemented a loadJSON function yesterday and wanted to make a pull request shortly. The implementation uses SFile and SURL so that JSON data can be loaded locally and from REST interfaces. I followed the proposal on the http://wiki.plantuml.net/site/preprocessing-json site. However, there are two more optional parameters. A default JSON if the data source does not provide any data and the possibility to define a charset encoding.

Here is an example:

@startuml

' This example works only with the latest plantuml snapshot an implemented
' %loadJSON function

' Default JSON, if we don't get a content from the data source
!$DEF={"status": "not connected"}

' Load from Spring boot service with actuator 'health' endpoint
!$TEST=%loadJSON("http://localhost:7778/management/health", $DEF)

' Load from local file (relative located in plantuml.include.path list)
!$DEMO=%loadJSON("demo.json")

title Load JSON example with $DEMO.status

' Simple usage
[Service] -> ($TEST.status): is

' Embedded rendering of JSON structure
 rectangle Inner #tan as "
    {{json
    $TEST
    }}
    Health of management service at %date()
    "
