options

问题 When I open a text file in Notepad, it shows a blank line if there is a carriage return at the end of the last line containing text. However, in Vim it does not show this blank line. Another thing I've noticed is that the Vim editor adds a carriage return to the last line by default (even though it doesn't show it). I can tell, because if I open a file in Notepad that was created in Vim, it shows a blank line at the end of the file. Anyway, I can live with these two differences, but I'm

问题 Is there any way to kick off OptionParser several times in one Ruby program, each with different sets of options? For example: $ myscript.rb --subsys1opt a --subsys2opt b Here, myscript.rb would use subsys1 and subsys2, delegating their options handling logic to them, possibly in a sequence where 'a' is processed first, followed by 'b' in separate OptionParser object; each time picking options only relevant for that context. A final phase could check that there is nothing unknown left after

问题 I have a configurable product with 3 options, see below: I want to replace the +£24.00 and the +£75.00 with the actual prices of the products. So instead it would say: £69.00 and £120.00 I have located the code being in js/varien/product.js I've spent a bit of time chopping and changing the code, but can't quite decipher what needs to change. Line 240 downwards in this file handles the JavaScript events for configurable products. I'd appreciate any help here. 回答1: This is performed by

问题 How can I implement options hashes? How is the structure of a class that has option hashes in it? Say I have a person class. I want to implement a method such as my_age that when called upon will tell me my age using options hashes. 回答1: You could do something like this: class Person def initialize(opts = {}) @options = opts end def my_age return @options[:age] if @options.has_key?(:age) end end and now you're able to call to the age like this p1 = Person.new(:age => 24)<br/> p2 = Person.new

问题 The data.table has a nice feature that suppresses output to the head and tail of the table. Is it possible to view / print more than 100 rows at once? library(data.table) ## Convert the ubiquitous "iris" data to a data.table dtIris = as.data.table(iris) ## Printing 100 rows is possible dtIris[1:100, ] ## Printing 101 rows is truncated dtIris[1:101, ] I often have data.table results that are somewhat large (e.g. 200 rows) that I just want to view. 回答1: The print method of data.table has an

问题 I used code from these posts (1,2) to create custom stock options: function add_custom_stock_type() { ?> <script type="text/javascript"> jQuery(function(){ jQuery('._stock_status_field').not('.custom-stock-status').remove(); }); </script> <?php woocommerce_wp_select( array( 'id' => '_stock_status', 'wrapper_class' => 'hide_if_variable custom-stock-status', 'label' => __( 'Stock status', 'woocommerce' ), 'options' => array( 'instock' => __( 'In stock', 'woocommerce' ), 'outofstock' => __( 'Out

问题 Usage: I have a form that has a select drop-down that's controlled by another select drop-down. On loading the page (if values where selected before, PHP loads them) select drop-down #2 hides several options (this works). When selecting a particular option with select drop-down #1, select drop-down #2 hidden options become available (.show(), this works). The problem: (An example to outline the problem: http://jsfiddle.net/RqhbY/7/) When the hidden options are shown/available and one is

问题 First, I'm asking this here, rather than on the Microsoft forums, because they're, well, you know what they are. I like the VS2015 Intellisense autocomplete features -- when I want them. But they've stupidly added the spacebar as a selection key. Even more stupidly, they've added the '.' the ':' and probably other boundary characters as selection keys, too. What this means, is I'm often typing happily along (and rather quickly), and whenever one of the "stupid" selection keys is pressed, I'm

问题 First question, ahhhh! Does anyone know / have info about why mongoose writes its debug log to stderr? Is there anyway to write it to stdout? 回答1: The debug option accepts a function instead of a boolean: mongoose.set("debug", function (collection, method, paramA, paramB, paramC) { console.log(collection) console.log(method) console.log(paramA) console.log(paramB) console.log(paramC) }) The reason I put paramA, paramB, paramC is because the arguments are dependent upon the method and options

问题 NOTE The keyword here is "default". I know I can hit escape and the default behavior gets aborted. I don't want to hit the escape key every time the IDE thinks it knows what I want. I didn't have to do this in 2013. ADDENDUM 2 It seems I'm still having difficulty communicating what I'm after here. What I want to happen is nothing when I press the space bar... I just want a space character to show up on my screen. The only time I want the IDE to actually insert a suggestion is when I hit the
