pack

问题 I am not able to get variable padding using d3.layout.pack().padding(). I want to put different padding at group and at leaf nodes. d3.layout.pack() .sort(null) .size([this.width , this.height]) .children(function (d) { return d.values; }) .value(function (d){ return 1; }) .padding(function (d){ return d.padding; }) .nodes({ values: outerClusterData }) // Sample data outerClusterData = [ { key: "africa", padding: 100, values: [ { name: "city1", padding: 10 }, { name: "city2", padding: 10 } ]

I understand little & big endian, but What's "machine byte order" mean? 回答1: In pack the phrase "machine byte order" means that the endianess is determined by the current machine 1 PHP itself makes no guarantees

问题 pack() syntax is (from http://php.net/manual/en/function.pack.php) string pack ( string $format [, mixed $args [, mixed $... ]] ) so assuming I need to pack three bytes $packed = pack( "c*", 65, 66, 67 ); But what if I have to pack an arbitrary number of bytes? They could coveniently be stored into an array so I naively tried $a = array( 65, 66, 67 ); $packed = pack( "c*", $a ); But it doesn't work. Is there a way to make pack() work with an array ? 回答1: At little late to the party, but for

问题 I am PHP beginner and my task is to build commands which will later be sent over UDP to a device. Running: OSX, PHP 5.5.3.8 To create the binary data I am using "pack". Here is an example of my code: <?php $in_1 = 0x3100; $in_2 = 0031; echo "Inputs: " . $in_1 . "\t" . $in_2; $bin = pack("v*", $in_1, $in_2); echo "\nlength: ". strlen($bin); printf ("\npacked result: %x \n",$bin); printf("HEX result %h\n", $bin); file_put_contents("ausgabe.log", $bin, FILE_APPEND); ?> the output in my terminal

问题 We are moving an e-commerce website to a new platform and because all of their pages are static html and they do not have all their product information in a database, we must scrape their current website for the product descriptions. Here is one of the pages: http://www.cabinplace.com/accrugsbathblackbear.htm What is the best was to get the description into a string? Should I use html agility pack? and if so how would this be done? as I am new to html agility pack and xhtml in general. Thanks

问题 I am trying to find out how I can pack an integer or float value in to a byte array in Julia. In Python I would just do the following: struct.pack("<q",1) Which would give me '\x01\x00\x00\x00\x00\x00\x00\x00' or for a float: struct.pack("<f",0.1) Is there any package in Julia that provides this? Thanks! 回答1: See the StrPack package: https://strpackjl.readthedocs.org/en/latest/ This is actually one of the oldest Julia packages around. 回答2: A couple other options to StrPack.jl: julia> function

问题 How can I get a similar function with pack/unpack (or other short function)? function getHEX($number) { switch($number) { case 0: $ret = "\x00\x00\x00\x00"; break; case 1: $ret = "\x00\x00\x00\x01"; break; case 2: $ret = "\x00\x00\x00\x02"; break; case 3: $ret = "\x00\x00\x00\x03"; break; // (...) default: $ret = "\x00\x00\x00\x00"; } return $ret; } 回答1: You could do it with dechex in PHP: <?php echo dechex(10) . "\n"; echo dechex(47); ?> 回答2: This function has solved my problem pack("H*",
