alias

问题 I would like to change the target of an alias using python. do I have to download some external library to do this. I played around with aliases a bit and can't figure out any way to edit them without user input. I'm using mac, python 2.6 回答1: As far as I can tell it should be possible using PyObjC to get at the Mac's Foundation library. I think NSURLBookmarkResolutionWithoutUI is what you are looking for. 回答2: PyObjC was a good suggestion. I couldn't find a solution anywhere, but after

问题 I am using VBA behind MS Access Say I have global methods foo1 and foo2 that gets the same arguments but do different things. I know that in C++ I can assign a function an alias. Something like: instead of: If (term) then foo1 arg1, arg2, arg3 else foo2 arg1, arg2, arg3 End If I want to write: Var new_func = Iff (term, foo1,foo2) new_func arg1, arg2, arg3 Can I do this on vba? 回答1: Would Run suit? new_func = IIf(term, "foo1", "foo2") ''new_func arg1, arg2, arg3 res = Run(new_func, "a", "b", 1

问题 I see this pattern every once in a while, especially in questions about Bash prompt customization. alias f='_ () { useful code; }; _' I can see no reason at all to create an alias here. The obvious refactoring f () { useful code; } which avoids declaring an alias altogether, and simply defines the function once and for all, seems simpler, more understandable, less brittle, and more efficient. (In case it's not obvious, the alias ends up redeclaring the function every time you invoke the alias

问题 Could someone help me interpret the alias function output for testing for multicollinearity in a multiple regression model. I know some predictor variables in my model are highly correlated, and I want to identify them using the alias table. Model : Score ~ Comments + Pros + Cons + Advice + Response + Value + Recommendation + 6Months + 12Months + 2Years + 3Years + Daily + Weekly + Monthly Complete : (Intercept) Comments Pros Cons Advice Response Value1 UseMonthly1 0 0 0 0 0 0 0

问题 Here are a list of aliases in C# (compliments of What is the difference between String and string in C#?): object: System.Object string: System.String bool: System.Boolean byte: System.Byte sbyte: System.SByte short: System.Int16 ushort: System.UInt16 int: System.Int32 uint: System.UInt32 long: System.Int64 ulong: System.UInt64 float: System.Single double: System.Double decimal: System.Decimal char: System.Char I can see bool through char being lowercase aliases, because they are primitive

问题 I'm not sure why but my Bash aliases don't seem to work. Here is my .bashrc file # v 0.0.1 - 7/03/12 [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting # expanding history to 10000 commands export HISTSIZE=10000 # don't store repeated commands more than once export HISCONTROL=ignoredups # where to look for Java export JAVA_HOME=/Library/Java/Home # tomcat server

问题 If I fail to explicitly call exit for certain function-based Bash scripts then there are additional unexpected executions for some functions. What is causing this? The behavior was first noticed while making a git alias as part of answering another user's question on StackOverflow. That alias was composed of this script ( which runs the function twice instead of once ): #!/usr/bin/env bash github(){ echo github; }; twitter(){ echo twitter; }; facebook(){ echo facebook; }; if [[ $(type -t "$1"

问题 So "cs" will be mapped to "/College/" so that I can run the command "cd cs"? 回答1: I believe you are asking about how to create a symbolic link (or symlink) like: ln -s College cs Although, there are other ways to speed up your workflow, such as setting the CDPATH: export CDPATH=.:~/:/College/ Or you could even make "cs" an alias that will perform the action "cd /College/": alias cs='cd /College/' If you did the above, you would type cs instead of cd cs to get there. See also ln - man page for

问题 I want to delete rows from a SQL Server 2000/2005 table variable based on the presence of other rows in the same table (delete all 0 count rows if a non-0 count row exists with the same date). Here is a simplified example that should only delete the row added first: declare @O table ( Month datetime, ACount int NULL ) insert into @O values ('2009-01-01', 0) insert into @O values ('2009-01-01', 1) insert into @O values ('2008-01-01', 1) insert into @O values ('2007-01-01', 0) delete from @O o1

问题 I am looking for a way to emit YAML files avoiding the use of aliases (mostly for simplified human readability). I think extending Psych::Visitors::Emitter or Psych::Visitors::Visitor is the way to go, but I cannot actually find where Ruby decides whether to dump an anchor in full, or reference it with an alias. I wouldn't even mind if the anchors were used repeatedly (with their &...... references), I just need to expand aliases to the full structures. I am aware of similar questions being
