Android Code Snippet PyJSON

Here's a treat for my Pythonic friends who got used to its JSON module!

Based on: https://docs.python.org/3/library/json.html

B4X Code Module:

Private Sub Process_Globals
    Public  Indent = 4 As Int
    Private gen As JSONGenerator
    Private par As JSONParser
End Sub

Public Sub LoadS(data As String) As Object
    Dim obj As Object 
    Do While True
        Try
            par.Initialize(data)
            obj = par.NextArray
            Exit
        Catch
            Pass
        End Try
        Try
            par.Initialize(data)
            obj = par.NextObject
            Exit
        Catch
            Pass
        End Try
        Try
            par.Initialize(data)
            obj = par.NextValue
            Exit
        Catch
            LogError(LastException)
        End Try
        Exit
    Loop
    Return obj
End Sub

Public Sub DumpS(obj As Object) As String
    If obj Is Map Then
        gen.Initialize(obj)
        Return gen.ToPrettyString(Indent)
    Else If obj Is List Then
        gen.Initialize2(obj)
        Return gen.ToPrettyString(Indent)
    End If
    Return obj
End Sub

Public Sub Dump(obj As Object, filedir As String, filename As String)
    File.WriteString(filedir, filename, DumpS(obj))
End Sub

Public Sub Load(filedir As String, filename As String) As Object
    Return LoadS(File.ReadString(filedir, filename))
End Sub

Public Sub Pretty(data As String) As String
    Return DumpS(LoadS(data))
End Sub

Private Sub Pass As Boolean
    Return True
End Sub

Usage:

'Module name: Json.bas

Json.Indent = 2 'Optional - default: 4
Dim obj = Json.Load(File.DirApp, "data.json") As Object
Log(Json.DumpS(obj))

Awesome, just what I needed as I'm so much more comfortable/productive with Python.

Many thanks.
