问题 I'm looking for a way to automatically format and color code I write in an HTML document. I know wikipedia does it, for example on the page: http://en.wikipedia.org/wiki/Nested_function I'm sure there are libraries out there to do this, but I can't for the life of me, find one. Does anyone have any suggestions? 回答1: Have a look at the Prettify JavaScript library. It's the one generally used by people (it's the one being used here on SO, for example.) You would use it like this: In your <head>

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

阅读更多关于 Printing Java Collections Nicely (toString Doesn't Return Pretty Output)

I wish to print a Stack<Integer> object as nicely as the Eclipse debugger does (i.e. [1,2,3...] ) but printing it with out = "output:" + stack doesn't return this nice result. Just to clarify, I'm talking about Java's built-in collection so I can't override its toString() . How can I get a nice printable version of the stack? You could convert it to an array and then print that out with Arrays.toString(Object[]) : System.out.println(Arrays.toString(stack.toArray())); String.join(",", yourIterable); (Java 8) tlavarea The MapUtils class offered by the Apache Commons project offers a MapUtils

How do I pretty-print HTML with Nokogiri?

阅读更多关于 How do I pretty-print HTML with Nokogiri?

问题 I wrote a web crawler in Ruby and I'm using Nokogiri::HTML to parse the page. I need to print the page out and while messing around in IRB I noticed a pretty_print method. However it takes a parameter and I can't figure out what it wants. My crawler is caching the HTML of the webpages and writing it to files on my local machine. I would like to "pretty print" the HTML so that it looks nice and properly formatted when I do so. 回答1: By "pretty printing" of HTML page I presume you meant that you

How can I “pretty” format my JSON output in Ruby on Rails?

阅读更多关于 How can I “pretty” format my JSON output in Ruby on Rails?

I would like my JSON output in Ruby on Rails to be "pretty" or nicely formatted. Right now, I call to_json and my JSON is all on one line. At times this can be difficult to see if there is a problem in the JSON output stream. Is there way to configure or a method to make my JSON "pretty" or nicely formatted in Rails? jpatokal Use the pretty_generate() function, built into later versions of JSON. For example: require 'json' my_object = { :array => [1, 2, 3, { :sample => "hash"} ], :foo => "bar" } puts JSON.pretty_generate(my_object) Which gets you: { "array": [ 1, 2, 3, { "sample": "hash" } ],

Pretty printing XML with javascript

I have a string that represents a non indented XML that I would like to pretty-print. For example: <root><node/></root> should become: <root> <node/> </root> Syntax highlighting is not a requirement. To tackle the problem I first transform the XML to add carriage returns and white spaces and then use a pre tag to output the XML. To add new lines and white spaces I wrote the following function: function formatXml(xml) { var formatted = ''; var reg = /(>)(<)(\/*)/g; xml = xml.replace(reg, '$1\r\n$2$3'); var pad = 0; jQuery.each(xml.split('\r\n'), function(index, node) { var indent = 0; if (node

NumPy: Pretty print tabular data

问题 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[\
