partial

问题 I have a extract of all the files on a network drive, and in the some file names is a part number, the part numbers format is 0000-000000-00 . Now in the 600,000+ path names in this file I'm trying to figure out how to extract my part numbers out of the path names. I think a mid formula might work but I am at a loss on how to tell it to find anything with the part # format 0000-000000-00 and extract only those 14 characters from the path? input looks like this c:\users\stuff\folder_name\1234

问题 I have the following code that allows me to search through the data on a table by using the option buttons I created that match the table headings. I can set the search criteria to be exact matches or partial. However, what I would like is to be able to search through different columns in the table without always having to go into the VBA code to toggle this option on and off. i.e some columns I would like an exact match, others I would like partial. Any help on where I can amend the code

问题 I have a partial that I want rendered with a collection and another variable. Is it possible to pass more than one variable to a partial? To illustrate: Category HABTM Brands This is just semi-pseudo-code, but I want to do something like: <% @categories.each do |c| %> <%= c.name %> <%= render :partial => "mypartial", :collection => c.brands, :object => c.id %> <% end %> The partial needs the category id as well as the "current_brand". Any ideas? 回答1: Inside of your view, you pass a hash to

问题 I want a regexp to match partial weekday names. For example, I want to match "Thursday", "thurs", "thur" or "Thu". I tried "thu(rsday)?", but that only matched "thu" and "thursday". The complete regular expression to match abbreviated weekdays would be excessively long. I tried this regex string: Mon(day)?|Tue(sday)?|Wed(nesday)?|Thu(rsday)?|Fri(day)?|Sat(urday)?|Sun(day)? The strings I have look like this: 3-Dec Mon 1:00pm Premiere USPHL Sk3-Red 4-Dec Tue 8:10pm U16 USPHL Sk3-Red 6-Dec Thur

问题 I am using this function of tensorflow to get my function jacobian. Came across two problems: The tensorflow documentation is contradicted to itself in the following two paragraph if I am not mistaken: gradients() adds ops to the graph to output the partial derivatives of ys with respect to xs. It returns a list of Tensor of length len(xs) where each tensor is the sum(dy/dx) for y in ys. Blockquote Blockquote Returns: A list of sum(dy/dx) for each x in xs. Blockquote According to my test, it

问题 Given interfaces A and B, which contain a x1 property in common interface A { a1: number; a2: number; x1: number; // <<<< } interface B{ b1: number; x1: number; // <<<< } And given the implementations a and b let a: A = {a1: 1, a2: 1, x1: 1}; let b: B = {b1: 1, x1: 1}; This simply passes, even though b1 does not belong to Partial<A> : let partialA: Partial<A> = b; but this fails because b1 does not belong to Partial<A> : let partialA: Partial<A> = {b1: 1, x1: 1}; Could someone please tell me

问题 I am using typescript@2.3.4. I have a target object: interface MyTarget { a: string; b: string; c: string; d: string; } I want to create multiple converts of partial objects using generics. One such convert might look like this: const convert = <T extends object>(t: T): MyTarget => { return { c: "c", d: "d", ...t, }; }; Yet this yields into: error TS2698: Spread types may only be created from object types. even though I guard the generic T to be an object . I then remember that there is a

问题 I have a regular expression that I'm testing a input stream of characters. I wonder if there is a way to match the regular expression against the input and determine if it is a partial match that consumes the entire input buffer? I.e. the end of the input buffer is reached before the regexp completes. I would like the implementation to decide whether to wait for more input characters, or abort the operation. In other words, I need to determine which one is true: The end of the input buffer

问题 I was thinking about how I could save myself from undefinition, and one idea I had was to enumerate all possible sources of partiality. At least I would know what of to beware. I found three yet: Incomplete pattern matches or guards. Recursion. (Optionally excluding structural recursion on algebraic types.) If a function is unsafe, any use of that function infects the user code. (Should I be saying "partiality is transitive"?) I have heard of other ways to obtain a logical contradiction, for

问题 I've created entity model for my DB classes, here is one of them: [EdmEntityTypeAttribute(NamespaceName="SotiModel", Name="SKUPrice")] [Serializable()] [DataContractAttribute(IsReference=true)] public partial class SKUPrice : EntityObject { ... } and created partial class for one of them public partial class SKUPrice { } The problem here is that 'partial' world is written in 'light' color and resharper suggests: 'partial class with a single part' . It seems like my 'own' part of partial class
