alias

问题 I created a Git alias based off of the Git Immersion tutorial by EdgeCase that looks like this: hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short But now it seems to be paging the results — Terminal shows (END) after the results are displayed, forcing me to hit Q to continue working. I read that by adding in the --no-pager tag, you can disable this feature; how do I incorporate it into the alias? I've tried it at the end, before the log , and right after, and none of

问题 Given my research, I don't believe the following is easily accomplished, if at all. As a last resort, however, I figured I'd check here. In Powershell 2.0, I'd like a way to reduce the (annoyingly) long names of parameters to various cmdlets. I would like absolute control over what the shorthand version looks like. (As opposed to being a slave to whatever parameter abbreviation scheme PS uses.) So, for example, I'd like to be able to do something like this: # Command goes on this first line

问题 I am working with multiply repositories. Is it possible to create an alias for repositories. So I can use them instead of raw urls? Namely instead of: svn ls https://mysvnrepos.abs/trunk I could use: svn ls myrepo 回答1: If you use Linux or Mac OS, you can define a global variable for your shell. export myrepo="https://mysvnrepos.abs/trunk" Then you can call svn ls $myrepo If you want to keep this variable, add the line above to your ~/.bashrc file (create it, if it does not exist). 回答2: No, I

问题 Why doesn't the following work? $ alias sayHello='/bin/echo "Hello world!"' $ sayHello Hello world! $ nohup sayHello nohup: appending output to `nohup.out' nohup: cannot run command `sayHello': No such file or directory (the reason I ask this question is because I've aliased my perl and python to different perl/python binaries which were optimized for my own purposes; however, nohup gives me troubles if I don't supply full path to my perl/python binaries) 回答1: Because the shell doesn't pass

问题 Perhaps I am demonstrating my ignorance of some oft-used feautre of C# or the .NET framework, but I would like to know if there is a natively-supported way to create a type alias like EmailAddress which aliases string but such that I can extend it with my own methods like bool Validate() ? I know of the using x = Some.Type; aliases but these are not global nor do they provide type safety, i.e. one could swap out an ordinary string for the using alias in the current file. I would like my

问题 In Python, you can set an alias for a module with 'as': import mymodule as mm But I can't seem to find an equivalent for ruby. I know that you can include rather than require a module, but this risks namespace collisions. Is there any equivalent to Python module aliases? 回答1: Modules in Ruby aren't really that special, so you can just assign them to another constant: [4] (pry) main: 0> module TestModule [4] (pry) main: 0* def self.foo [4] (pry) main: 0* "test" [4] (pry) main: 0* end [4] (pry)

问题 Does somebody know why this works with both table alias "x"? Select x.company_name ,x.employee_name FROM company x JOIN employee x ON x.company_id = 5 I know that the JOIN with id 5 makes no sense... Thanks for the lesson! 回答1: The first two queries below are equivalent. In the ON clause of the join the table alias x only refers to the last table to use that alias so only the employee table is restricted. In the SELECT and WHERE expressions the x alias refers to both tables - so, where the

问题 Let's have a following example: public class X { } public class Y { } public class Z { } public delegate IDictionary<Y, IList<Z>> Bar(IList<X> x, int i); public interface IFoo { // ... Bar Bar { get; } } public class Foo : IFoo { // ... public Bar Bar { get { return null; //... } } } void Main() { IFoo foo; //= ... IEnumerable<IList<X>> source; //= ... var results = source.Select(foo.Bar); // <- compile error here } The compiler says: The type arguments for method 'System.Linq.Enumerable
