node.js - fs.readFile().toString terminated by empty string -

-

the following node script, (wc.js) return value wich different unix utility wc;

fs = require('fs'); //console.log(fs.readfilesync(process.argv[2]).tostring().split('\n') ); console.log(fs.readfilesync(process.argv[2]).tostring().split('\n').length );

the output on itself, is:

vagrant@precise32:~/stuff$ wc -l wc.js 3 wc.js vagrant@precise32:~/stuff$ node wc.js wc.js 4

and printing array, seems file get's terminated empty string:

vagrant@precise32:~/stuff$ node wc.js wc.js [ 'fs = require(\'fs\');', 'console.log(fs.readfilesync(process.argv[2]).tostring().split(\'\\n\') );', '//console.log(fs.readfilesync(process.argv[2]).tostring().split(\'\\n\').length );', '' ]

is expected behavior? cannot see reported in node documentation.

are sure don't have trailing newline character @ end of file?

$ node wc.js wc.js [ 'fs = require(\'fs\');',   'console.log(fs.readfilesync(process.argv[2]).tostring().split(\'\\n\') );',   '// console.log(fs.readfilesync(process.argv[2]).tostring().split(\'\\n\').length );' ]

you can ignore last newline character .replace(/\n$/, ''), believe behavior of wc.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
