indentation behaviour incorrect using phpeclipse code templates. if code indented @ start of template insertion, indent depth ignored , tabs used if use spaces indenting. example: "function" code template, inserted when indent depth 4 spaces: function function_name( $param ) { // 4 spaces return ; // tab? } // nothing! i specified use spaces in window -> preferences -> phpeclipse -> php -> typing tab -> checked insert spaces tab and window -> preferences -> phpeclipse -> php -> formatter -> style tab -> unchecked indentation represented tab i tried use tabs, nothing: function function_name( $param ) { // 1 tab return ; // 1 tab... (*sigh*) } // nothing! i checked code template, seems correct , similar java code templates, work expected. "use code formatter" checked. , goog...

i'm trying come way html/text user sees on given url, though of see may produced dynamically (on page-load, example) not in dom, manually loading javascripts , putting resulting data page. my thinking this: (naively) return array of javascript files scraping <script> tags src attribute. return array of on-page hard-coded javascripts like: <script> var example = true; </script> create function decide real urls encountered in internal , external page javascripts. example, when encountering example $.ajax({ url: '/relative-js-file.js' , figure out absolute url php may access page. using php, load of javascript found on page in way resembles being loaded on actual page (the page came from). take whatever data javascript returns (plain, html, etc.), , inject new plain-text and/or html original page <body> . i realize not work lot of time, hope @ least starting point until can find better solution or create more advanced function handle u...

i generating groundwater elevation contour matplotlib. see below here have now; how can add water flow arrows image below? i want add arrows make this: if has ideas and/or code samples appreciated. you'll need recent (>= 1.2) version of matplotlib, streamplot this. need take negative gradient of head (a.k.a. "water table" surface aquifers) grid. as quick example generated random point observations of head: import numpy np scipy.interpolate import rbf import matplotlib.pyplot plt # make data repeatable np.random.seed(1981) # generate random wells random head (water table) observations x, y, z = np.random.random((3, 10)) # interpolate these onto regular grid xi, yi = np.mgrid[0:1:100j, 0:1:100j] func = rbf(x, y, z, function='linear') zi = func(xi, yi) # -- plot -------------------------- fig, ax = plt.subplots() # plot flowlines dy, dx = np.gradient(-zi.t) # flow goes down gradient (thus -zi) ax.streamplot(xi[:,0], yi[0,:], dx, dy, co...

i have used java quite long time, never did find out, makes factories special. can please explain me? there reason why should want implement own factory (if it's possible)? factory patterns fantastic decoupling classes. example, let's assume common interface, animal , , classes implement it. dog , cat . if not know user want generate @ run time, can not create dog pointer. won't work! what can though, port separate class, , @ run time, pass discriminator factory class. class return object. example: public animal getinstance(string discriminator) { if(discriminator.equals("dog")) { return new dog(); } // etc. } and calling class uses: string type = "dog"; animal value = factory.getinstance(type); this makes code extremely readable, separates decision logic logic performed on value , decouples classes via common interface. in all, pretty nice pattern!

i have multiple elements that'll have same data attributes different values, how can jquery change value? below example html. <div data-one="test" data-two="test2"></div> <div data-one="testing" data-two="hello"></div> <div data-one="yo" data-two="test3"></div> by default, value of div data-one when class active on body tag, change values data-two value. i thought storing values variable easier although divs don't have id's , they're scattered around in dom makes difficult. so far had this: if($('body').hasclass('active')) { $('div').html($(div).data('two')); } you can use html method. var has = $('body').hasclass('active'); $('div').html(function() { return has ? $(this).data('two') : $(this).data('one'); }); http://jsfiddle.net/44du5/
