pretty-print

问题 Is jq the best choice for pretty-printing arbitrary JSON? cat my.json | jq . pretty-prints the given JSON, but expands every field on a separate line. But what if some of the fields are repetitive, such as a list of points? How can fields that match a pattern be formatted on a single line with --compact-output ? For example, format "coords" and "list" fields below on a single line: [ { "field1": { "a": "", "b": "" "list": [{ "name": "x", "score": 1, "rect": { "x": 156, "y": 245, "w": 35, "h":

问题 I have a dictionary of lists and the lists are quite long. How can I print it in a way that only a few elements of the list show up? Obviously, I can write a custom function for that but is there any built-in way or library that can achieve this? For example when printing large data frames, pandas prints it nicely in a short way. This example better illustrates what I mean: obj = {'key_1': ['EG8XYD9FVN', 'S2WARDCVAO', 'J00YCU55DP', 'R07BUIF2F7', 'VGPS1JD0UM', 'WL3TWSDP8E', 'LD8QY7DMJ3',

问题 Using json.dumps I have the following output. { "1": { "fooBar": { "_foo": "foo", "_bar": "bar", "_id": "1" }, "longValueList": [ [ 1, 2, ... n, ], ... The above output is generated using this class object function. def toJSON(self): return json.dumps(self._container, default=lambda o: o.__dict__, sort_keys=True, indent=4) The key longValueList is associated with really long value list and I do not need it printed when doing these specific json prints. How can prevent pythons json.dumps from

问题 What I get from jq is: { "frameGrid": { "size": [ 24, 24 ], "dimensions": [ 1, 1 ], "names": [ [ "default" ] ] } } What I would like to see is something more like this: { "frameGrid": { "size": [24,24], "dimensions": [1,1], "names": [["default"]] } } I know both forms are valid, and that jq has a compact/pretty print mode. But is there something in-between? I'm looking to somehow format a larger json file that has many more array values than this, so that it's easily readable and printable.

问题 I am using the GoogleTest (GTest) framework in conjunction with a Qt5 application. Whenever a test fails using a QString argument, the framework tries to print all the involved values. However, it cannot automatically handle foreign types (Qt5's QString in this case). QString test = "Test"; ASSERT_EQ(test, "Value"); How can I get GoogleTest to pretty print QStrings automatically (= without having to manually convert them each time)? 回答1: The GoogleTest Guide explains how you can in general

问题 I am trying to print the current date when the template is activated. I have read that I have to pass a new Date() Java object to the template, but I don't know how to do that or where to put it in the code. Does someone know how to pass a Java object to the template in this case? Thank you !! 回答1: Actually you don't have to pass a new Date() to your template, because placing a timestamp into a template's output is quite common and therefore FreeMarker provides a special variable called .now

问题 Anyone got a ready made function that will take an XML string and return a correctly indented string? eg <XML><TAG1>A</TAG1><TAG2><Tag3></Tag3></TAG2></XML> and will return nicely formatted String in return after inserting linebreaks and tabs or spaces? 回答1: The RTL has FormatXMLData in XMLDoc.pas that accepts and returns strings. 回答2: Using OmniXML: program TestIndentXML; {$APPTYPE CONSOLE} uses SysUtils, OmniXML, OmniXMLUtils; function IndentXML(const xml: string): string; var xmlDoc:

问题 Customizing pprint.PrettyPrinter The documentation for the pprint module mentions that the method PrettyPrinter.format is intended to make it possible to customize formatting. I gather that it's possible to override this method in a subclass, but this doesn't seem to provide a way to have the base class methods apply line wrapping and indentation. Am I missing something here? Is there a better way to do this (e.g. another module)? Alternatives? I've checked out the pretty module, which looks

问题 I am using this simple code to print an array as a JSON structure. header('Content-Type: application/json'); echo json_encode($this->data, JSON_PRETTY_PRINT); I'm using Chrome Version 28.0.1500.95 m. For some odd reason the output is wrapped in a pre tag with a tab character (i.e. \t ) at the beginning. JSON seems to be parsing okay but I still get that tab character when no data is sent. How can I fix this ? <pre style="word-wrap: break-word; white-space: pre-wrap;"> { "title": "Node",
