  • get bash history to vi

    - by nameanyone
    When I try to read bash history into vim, I get nothing. :r !history If I just execute the command, i.e. :!history instead of history I get a snapshot of my terminal as it looked before I started vim. How can I read the output of "history" into vim? Reading the contents of .bash_history won't do as I save history with timestamps: HISTTIMEFORMAT='%Y.%m.%d %R '

  • $.ajax ColdFusion cfc JSON Hello World

    - by cf_PhillipSenn
    I've simplified this example as much as I can. I have a remote function: <cfcomponent output="false"> <cffunction name="Read" access="remote" output="false"> <cfset var local = {}> <cfquery name="local.qry" datasource="myDatasource"> SELECT PersonID,FirstName,LastName FROM Person </cfquery> <cfreturn local.qry> </cffunction> </cfcomponent> And using the jQuery $.ajax method, I would like to make an unordered list of everyone. <!DOCTYPE HTML> <html> <head> <script src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1"); </script> <script type="text/javascript"> jQuery(function($){ $.ajax({ url: "Remote/Person.cfc?method=Read&ReturnFormat=json", success: function(data){ var str = '<ul>'; // This is where I need help: for (var I=0; I<data.length; I++) { str += '<li>' + I + data[I][1]+ '</li>' } str += '</ul>'; $('body').html(str); }, error: function(ErrorMsg){ console.log("Error"); } }); }); </script> </head> <body> </body> </html> The part where I'm lost is where I'm looping over the data. I prefer to the use jQuery $.ajax method because I understand that $.get and $.post don't have error trapping. I don't know how to handle JSON returned from the cfc.

  • Code golf: Reverse quine

    - by Eduardo León
    Write a program that outputs the reverse of its source code as a string. If the source is abcd efg (i.e., the C string "abcd\nefg") Then the output should be gfe dcba (i.e., the C string "gfe\ndcba") Bonus points for using esoteric languages such as brainf*ck. *EDIT:** Removed the unnecessary \0 characters.+

    I'm getting a System.NullReferenceException when my application starts up (after a small login screen) which doesn't crash the entire app but prevents it from loading correctly.

  • Do WordPress widget (or sidebar) hooks exist?

    - by Jeff
    I'm trying to filter ALL widget output through a simple filter, but can't find any hooks and was hoping to be pointed in the right direction. Or possibly my efforts are not even possible? My simple filter is something like this: function clean_widget_output( $input ) { return str_replace( array( "\t", "\n", "\r" ), '', $input ); } add_[FILTER OR ACTION]( 'need_a_hook', 'clean_widget_output', 99 ); Any ideas? I'm pretty new to PHP, but I can get around.

  • Netstat -ban (or -oan) equivalent in C#

    I'd like to know if a particular process is using a given port, i.e. netstat -ban. I came across using IPGlobalProperties to get the list of active connections, but this doesn't seem to include process information. It would be nice if there exists some class in C# that lets me do this programmatically. Ideally, I wouldn't have to pipe the cmd shell Process output. Thanks in advance.

  • MSBuild: Items + Batching + CreateItem + Transforms Question

    - by KeithCS
    I have this bit of an msbuild project that is making me wonder why it the outcome is the way it is. Not that it is causing an issue or anything of the sort, but I would like to try and better my understanding of it. <?xml version="1.0" encoding="utf-8" ?> <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="TestTarget1;TestTarget2" ToolsVersion="3.5"> <ItemGroup> <PathDir Include="C:\RootDir\UniqueDir1"/> <PathDir Include="C:\RootDir\UniqueDir2" /> </ItemGroup> <Target Name="TestTarget1" Outputs="%(PathDir.Identity)"> <PropertyGroup> <RootPath>%(PathDir.Identity)</RootPath> </PropertyGroup> <ItemGroup> <SubDirectory Include="Common1"/> <SubDirectory Include="Common2"/> </ItemGroup> <CreateItem Include="@(SubDirectory->'$(RootPath)\%(Identity)')"> <Output TaskParameter="Include" ItemName="FullPath"/> </CreateItem> <Message Text="@(FullPath)"/> </Target> <Target Name="TestTarget2"> <Message Text="@(FullPath)"/> </Target> </Project> So I have two main paths that are unique, and within each I have two directories with the same names in each of the unique paths. In target1, I am batching against the identity of the items in PathDir, and then performing a transform on item SubDirectory, which contains the common folder names found in the unique directories, to create a new item containing the full paths. So anyways, after that, the output for the targets is as follows: Target 1: C:\RootDir\UniqueDir1\Common1;C:\RootDir\UniqueDir1\Common2 C:\RootDir\UniqueDir2\Common1;C:\RootDir\UniqueDir2\Common2 Target 2: C:\RootDir\UniqueDir1\Common1;C:\RootDir\UniqueDir1\Common2;C:\RootDir\UniqueDir2\Common1;C:\RootDir\UniqueDir2\Common2 So my question I guess is ... why does target1 only display the directories containing the directory it is batching against? I know it probably has to do with batching, but thats all I know.
