Hypergraphia Indulged

The link to the source is broken :(

My apologies for barging in here, knowing nothing about any of this---and not belonging here at all. But I just wanted to say, Geewhiz! If I knew about all of this stuff, my hypergraphia could take off in an entirely new direction. Unfortunately, I don't induge mine. It indulges me a moment or two of calm every once in awhile. Oh well.

Thank you for this code! It's simple and gets the job done! You saved me a bunch of time!

I had to tweak it because we are currently using Gson 1.3, and I added a couple of ppJson() overloads, one that takes a JsonElement in case you already have one all parsed and one that takes a String with Json in it, and returns it pretty-printed. That's what I really needed was to reformat unformatted Json.

Besides the added methods, I modified the ppJson method that calls gson.toJsonTree() to construct a JsonElement. For Gson 1.3, you use gson to make the JSON string then you create a JsonElement from that. Below is the modified method and the two new overloads.

Thanks again!


public void ppJson(final Object o, final PrintWriter pw, Type t) {

final String jsonString = gson.toJson(o, t);
final JsonParser parser = new JsonParser();

final JsonElement jsonTree = parser.parse(jsonString);
final List<String> stringList = toStringList(jsonTree);
for (final String s : stringList) {
pw.println(s);
}
}

public String ppJson(final String jsonString) {
final JsonParser parser = new JsonParser();
final JsonElement jsonTree = parser.parse(jsonString);

final StringWriter sw = new StringWriter(128);
final PrintWriter pw = new PrintWriter(sw);
ppJson(jsonTree, pw);

return new String(sw.toString());
}

public void ppJson(final JsonElement jsonElement, final PrintWriter pw) {
final List<String> stringList = toStringList(jsonElement);
for (final String s : stringList) {
pw.println(s);
}
}


thanks for that one ! it does the job beautifully

(i don't get why such a formatter is not included is the default distribution :/)

thanks for the code. it makes my work pretty

A sail veering about the blank bay waiting for a swollen designer sunglasses wholesale bundle to bob up, roll over to the sun a puffy replica sunglasses wholesale face, salt white. Here I am. They followed the winding path down to the creek. Buck Mulligan stood on a stone, in shirtsleeves, his wholesale cheap sunglasses unclipped tie rippling over his shoulder. A young man clinging to a spur of rock near him moved slowly frogwise his green sunglass wholesale legs in the deep jelly of the water. Buck Mulligan sat down to unlace his wholesale oakley sunglasses boots. An elderly man shot up near the spur of rock a blowing red sunglasses for wholesale face. He scrambled up by the stones, water glistening on his fashion sunglasses wholesale pate and on its garland of grey hair, water rilling over his chest and paunch and spilling jets out of his wholesale sunglasses china black sagging loincloth.
