November 11, 2022 by Tarik

In your main app.js or what is in it’s place: Express 4.x if (app.get(‘env’) === ‘development’) { app.locals.pretty = true; } Express 3.x app.configure(‘development’, function(){ app.use(express.errorHandler()); app.locals.pretty = true; }); Express 2.x app.configure(‘development’, function(){ app.use(express.errorHandler()); app.set(‘view options’, { pretty: true }); }); I put the pretty print in development because you’ll want more efficiency with … Read more

Pretty-Print JSON Data to a File using Python

October 23, 2022 by Tarik

You should use the optional argument indent. header, output = client.request(twitterRequest, method=”GET”, body=None, headers=None, force_auth_header=True) # now write output to a file twitterDataFile = open(“twitterData.json”, “w”) # magic happens here to make it pretty-printed twitterDataFile.write(simplejson.dumps(simplejson.loads(output), indent=4, sort_keys=True)) twitterDataFile.close()

Convert JSON String to Pretty Print JSON output using Jackson

October 18, 2022 by Tarik

To indent any old JSON, just bind it as Object, like: Object json = mapper.readValue(input, Object.class); and then write it out with indentation: String indented = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json); this avoids your having to define actual POJO to map data to. Or you can use JsonNode (JSON Tree) as well.

Printing Java Collections Nicely (toString Doesn’t Return Pretty Output)

You could convert it to an array and then print that out with Arrays.toString(Object[]): System.out.println(Arrays.toString(stack.toArray()));

How do I get python’s pprint to return a string instead of printing?

October 9, 2022 by Tarik

The pprint module has a function named pformat, for just that purpose. From the documentation: Return the formatted representation of object as a string. indent, width and depth will be passed to the PrettyPrinter constructor as formatting parameters. Example: >>> import pprint >>> people = [ … {“first”: “Brian”, “last”: “Kernighan”}, … {“first”: “Dennis”, “last”: … Read more

Formatting floats without trailing zeros

October 7, 2022 by Tarik

Me, I’d do (‘%f’ % x).rstrip(‘0’).rstrip(‘.’) — guarantees fixed-point formatting rather than scientific notation, etc etc. Yeah, not as slick and elegant as %g, but, it works (and I don’t know how to force %g to never use scientific notation;-).

Pretty-Print JSON in Java

October 3, 2022 by Tarik

Google’s GSON can do this in a nice way: Gson gson = new GsonBuilder().setPrettyPrinting().create(); JsonParser jp = new JsonParser(); JsonElement je = jp.parse(uglyJsonString); String prettyJsonString = gson.toJson(je); or since it is now recommended to use the static parse method from JsonParser you can also use this instead: Gson gson = new GsonBuilder().setPrettyPrinting().create(); JsonElement je = … Read more

How can I pretty-print JSON using Go?

September 30, 2022 by Tarik

By pretty-print, I assume you mean indented, like so { “data”: 1234 } rather than {“data”:1234} The easiest way to do this is with MarshalIndent, which will let you specify how you would like it indented via the indent argument. Thus, json.MarshalIndent(data, “”, ” “) will pretty-print using four spaces for indentation.

Pretty-print a NumPy array without scientific notation and with given precision

September 18, 2022 by Tarik

Use numpy.set_printoptions to set the precision of the output: import numpy as np x = np.random.random(10) print(x) # [ 0.07837821 0.48002108 0.41274116 0.82993414 0.77610352 0.1023732 # 0.51303098 0.4617183 0.33487207 0.71162095] np.set_printoptions(precision=3) print(x) # [ 0.078 0.48 0.413 0.83 0.776 0.102 0.513 0.462 0.335 0.712] And suppress suppresses the use of scientific notation for small numbers: … Read more
