问题 I'm using GNAT GPS studio IDE in order to train a bit in Ada. I'm having an issue with package visibility. First I specify a package in a file called "DScale.ads" containing a type: package DScale is type DMajor is (D, E, F_Sharp, G, A, B, C_Sharp); end DScale; Then I specify in a different file ("Noteworthy.ads") a package that defines a procedure that will use the DMajor type of the DScale package: with Ada.Text_IO; with DScale; package NoteWorthy is procedure Note; end NoteWorthy; Finally

问题 I've made a desktop-friendly django app and would prefer not to have to rewrite all of the html/css to allow proper view on mobile browsers. I'm on django 1.5 and python 2.7 Is there a package or library or quicker way to efficiently create a mobile version of my django (web) app instead of having to re-write a whole new template with html/css ? Thank you! 回答1: In a word, no. You're going to have to rewrite most of your templates to be "responsive" to smaller (mobile) screen sizes. I'd

问题 Can one use the same python package (wheel file) for Linux , windows etc.? I am asking this as some packages include not only python files but EXEs as well, which I assume are python code turned into exe (at least with pip.exe and Django admin tool). Exe files are platform specific in the same way there are separate python interpreters for windows and Linux so that arises a question. 回答1: Some wheel packages are cross-platform; some are platform-specific. This information is included in the

问题 After pulling some code updates I found I got this message when building. Some NuGet packages are missing from the solution. The packages need to be restored in order to build the dependency graph. Restore the packages before performing any operations In solution explorer the references links displayed with a missing reference icon I deleted the references Then at the package manager console a button appeared asking if I wanted to install the missing packages. However, this did not work. 回答1:

问题 I have my small program.jar that uses a small part of huge library.jar. Is there a tool to repackage several jars into one so it can be run stand-alone and is as small as possible? Update: size matters. 回答1: There is proguard, with ant and maven plugins. It removes unused code, optionally obfuscates and compresses to a single jar. Proguard reduces the size on two fronts only the classes that are actually used are stored in the final jar. Long names, e.g. all the long package names, class

问题 (This isn't a homework question, as it's above and beyond the class just for my personal interest.) In my Java class this semester, our instructor is giving us the compiled JUnit tests that our completed labs should pass. For example, our first lab was to design this class: package java112.labs1; public class MysteryClassOne { public int mysteryMethodOne() { return 1; } } This is very trivial Java code and to give myself a bit more of a challenge as I've had previous Java experience, I'd like

问题 In my `package.json' file, it seems that all the Angular depedencies are prefixed by @. What does this mean? E.g. "dependencies": { "@angular/common": "2.0.0-rc.5", Why not just as below, with no @? "dependencies": { "angular/common": "2.0.0-rc.5", 回答1: npm has two types of modules: Global modules - npm install mypackage Scoped modules - npm install @myorg/mypackage Scopes are a way of grouping related packages together, and also affect a few things about the way npm treats the package. 来源：

问题 I have two jar files from a client, one of which is used for a testing and another for final versions. Currently I put them in different folders and modify the library path when deploying our code, but it would be nice to be able to load both jar files and switch between them dynamically at runtime. Is this possible? 回答1: You can always write your own ClassLoader and chain it with the standard ClassLoader. http://download.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html I used this
