This is a very simple JSON parser. I'm sure it could be a lot better but I just wanted something quick. It only works with 1 level. If anyone has a better solution please post. Sorry for lack of commenting. Wink

{"firstName":"Chris","lastName":"Gingerich"}

Code:

  #define function,json
  #define command,json

  #%t = @json(create)
  #json write,%t,name,VDSFreak
  #json write,%t,email,"chris@insuresign.com"
  #info @json(text,%t)
  #info @json(read,%t,email)
  #stop

:json
  #very simple JSON parser
  #%t = @json(create)
  # Creates a JSON ID (a list)
  #%t = @json(read,<JSON ID>,<name>,<default value>)
  #%t = @json(text,<JSON ID>)
  #json loadfile,<JSON ID>,<File name>
  #json write,<JSON ID>,<name>,<value>
  #json savefile,<JSON ID>,<file name>
  if @not(%1)
    error 2
  end
  if @equal(%1,read)
    if @not(%2)
      error 2
    end
    %%_json_text = @text(%2)
    #first try with ,
    %%exit = @strslice(%%_json_text,@chr(34)%3@chr(34):@chr(34),@chr(34)@chr(44))
    if @not(%%exit)
      #then with }
      %%exit = @strslice(%%_json_text,@chr(34)%3@chr(34):@chr(34),@chr(34)"}")
    end
    if @not(%%exit)
      if %4
        %%exit = %4
      end
    end
    #end
    exit %%exit
  elsif @equal(%1,write)
    if @not(%2)
      error 2
    end
    #get the text from the list
    %%_json_text = @trim(@text(%2))
    %p = @pos(@chr(34)%3@chr(34):@chr(34),%%_json_text)
    if @not(@greater(%p,0))
      %c = @pos("}",%%_json_text)
      if @equal(%%_json_text,"{}")
        #if a new JSON string don't add the ,
        %%exit = @strins(%%_json_text,%c,@chr(34)%3@chr(34):@chr(34)%4@chr(34))
      else
        %%exit = @strins(%%_json_text,%c,@chr(44)@chr(34)%3@chr(34):@chr(34)%4@chr(34))
      end
      list clear,%2
      list add,%2,%%exit
      exit
    else
      %l = @len(@chr(34)%3@chr(34):@chr(34)@chr(44))
      %s = @sum(%l,@pred(%p))
      %%p2 = @pred(@pos(@chr(34),%%_json_text,%s))
      %e = @strdel(%%_json_text,%s,%%p2)
      %%exit = @strins(%e,%s,%4)
      list clear,%2
      list add,%2,%%exit
      exit
    end
  elsif @equal(%1,create)
    %l = @new(list)
    list add,%l,"{}"
    exit %l
  elsif @equal(%1,text)
    if @not(%2)
      error 2
    end
    exit @text(%2)
  elsif @equal(%1,savefile)
    if @not(@both(%2,%3))
      error 2
    end
    list savefile,%2,%3
  elsif @equal(%1,loadfile)
    if @not(%2)
      error 2
    end
    list loadfile,%2,%3
    exit
  end
  exit



EDIT: Updated to use a list

Nice!

Yeah to go to nested levels will be a different beast. I remember struggling with this grabbing inner windows and with the original array function.

Thanks. Seems like everything outputs to json and I like using this more than an ini file for writing to disk.

I vaguely remember someone going through this issue when they were trying to work with XML files. I am sure they had a solution to this. This was before VDS offered support for XML files. Try searching the forums for the XML threads.

Found it, thanks Garrett.

I'll take a look and see if I can use it for JSON
