Is there a pretty print for PHP?

由 只愿长相守 提交于 2019-11-27 05:01:06
问题 I'm fixing some PHP scripts and I'm missing ruby's pretty printer. i.e. require 'pp' arr = {:one => 1} pp arr will output {:one => 1}. This even works with fairly complex objects and makes digging into an unknown script much easier. Is there some way to duplicate this functionality in PHP? 回答1: Both print_r() and var_dump() will output visual representations of objects within PHP. $arr = array('one' => 1); print_r($arr); var_dump($arr); 回答2: This is what I use to print my arrays: <pre> <?php

How can I pretty-print JSON using Go?

由 丶灬走出姿态 提交于 2019-11-27 05:00:27
问题 Does anyone know of a simple way to pretty-print JSON output in Go? The stock http://golang.org/pkg/encoding/json/ package does not seem to include functionality for this (EDIT: it does, see accepted answer) and a quick google doesn't turn up anything obvious. Uses I'm looking for are both pretty-printing the result of json.Marshal and just formatting a string full of JSON from wherever, so it's easier to read for debug purposes. 回答1: By pretty-print, I assume you mean indented, like so {

NumPy: Pretty print tabular data

由 陌路散爱 提交于 2019-11-27 04:39:06
I would like to print NumPy tabular array data, so that it looks nice. R and database consoles seem to demonstrate good abilities to do this. However, NumPy's built-in printing of tabular arrays looks like garbage: import numpy as np dat_dtype = { 'names' : ('column_one', 'col_two', 'column_3'), 'formats' : ('i', 'd', '|S12')} dat = np.zeros(4, dat_dtype) dat['column_one'] = range(4) dat['col_two'] = 10**(-np.arange(4, dtype='d') - 4) dat['column_3'] = 'ABCD' dat['column_3'][2] = 'long string' print(dat) # [(0, 0.0001, 'ABCD') (1, 1.0000000000000001e-005, 'ABCD') # (2, 9.9999999999999995e-007,

Pretty print in lxml is failing when I add tags to a parsed tree

由 隐身守侯 提交于 2019-11-27 03:45:19
问题 I have an xml file that I'm using etree from lxml to work with, but when I add tags to it, pretty printing doesn't seem to work. >>> from lxml import etree >>> root = etree.parse('file.xml').getroot() >>> print etree.tostring(root, pretty_print = True) <root> <x> <y>test1</y> </x> </root> So far so good. But now >>> x = root.find('x') >>> z = etree.SubElement(x, 'z') >>> etree.SubElement(z, 'z1').attrib['value'] = 'val1' >>> print etree.tostring(root, pretty_print = True) <root> <x> <y>test1<

How do I print out a tree structure?

由 牧云@^-^@ 提交于 2019-11-27 03:11:22
I'm trying to improve performance in our app. I've got performance information in the form of a tree of calls, with the following node class: public class Node { public string Name; // method name public decimal Time; // time spent in method public List<Node> Children; } I want to print out the tree such that I can see lines between the nodes - something like in this question . What's an algorithm I can use in C# for doing that? Edit: Obviously I need to use recursion - but my attempts keep putting the lines in the wrong places. What I'm asking for is a specific algorithm that will print the

Jax-rs json pretty output

问题 in Java when i use the @Produces("application/json") annotation the output is not formated into human readable form. How do i achive that? 回答1: Just for the record, if you want to enable the pretty output only for some resources you can use the @JacksonFeatures annotation on a resource method. Here is example: @Produces(MediaType.APPLICATION_JSON) @JacksonFeatures(serializationEnable = { SerializationFeature.INDENT_OUTPUT }) public Bean resource() { return new Bean(); } 回答2: Create this class

Pretty print XML in java 8

问题 I have an XML file stored as a DOM Document and I would like to pretty print it to the console, preferably without using an external library. I am aware that this question has been asked multiple times on this site, however none of the previous answers have worked for me. I am using java 8, so perhaps this is where my code differs from previous questions? I have also tried to set the transformer manually using code found from the web, however this just caused a not found error. Here is my
