  • How to create a bash function with variable parameters/arguments to grep several keywords/tags

    - by CornSmith
    I'm using the :!grep "tag1" filename | grep "tag2" filename | grep -n "tag3 or more" filename command in vim to search for my code snippets based on their tags (a simple comment at the top of a snippet) in one big file. I use snippets to remember tricky things. This is painful to write out each time. I'd like to make an alias, or function to do something like this: :!greptag tag1 tag2 ... tag39 And it should search the current doc and return the lines with all the tags on them. Vim is set to interactive shell mode so that it can parse my bashrc for aliases/functions. set shellcmdflag=-ic How can I construct a function that allows for variable arguments like this in bash?

  • How to create a better tables Structure.

    - by user160820
    For my website i have tables Category :: id | name Product :: id | name | categoryid Now each category may have different sizes, for that I have also created a table Size :: id | name | categoryid | price Now the problem is that each category has also different ingredients that customer can choose to add to his purchased product. And these ingredients have different prices for different sizes. For that I also have a table like Ingredient :: id | name | sizeid | categoryid | price I am not sure if this Structure really normalized is. Can someone please help me to optimize this structure and which indexed do i need for this Structure?

  • How to create newline in a rebol block ?

    - by Rebol Tutorial
    let's say I have a config.txt which contains: "param11" "param12" "param21" "param22" I'll load it in memory with config: load %config.txt I can save it back with save %config.txt config So far so good. Now the problem occurs for me when I want to add "param31" "param32" I have tried append config reduce [newline "param31" "param32"] save %config.txt config But that doesn't give the expected result "param11" "param12" "param21" "param22" "param31" "param32" but this instead "param11" "param12" "param21" "param22" #"^/" "param31" "param32" So how to ?

  • Using Visual Studio 2010 Express to create a surface I can draw to

    - by Joel
    I'm coming from a Java background and trying to port a simple version of Conway's Game of Life that I wrote to C# in order to learn the language. In Java, I drew my output by inheriting from JComponent and overriding paint(). My new canvas class then had an instance of the simulation's backend which it could read/manipulate. I was then able to get the WYSIWYG GUI editor (Matisse, from NetBeans) to allow me to visually place the canvas. In C#, I've gathered that I need to override OnPaint() to draw things, which (as far as I know) requires me to inherit from something (I chose Panel). I can't figure out how to get the Windows forms editor to let me place my custom class. I'm also uncertain about where in the generated code I need to place my class. How can I do this, and is putting all my drawing code into a subclass really how I should be going about this? The lack of easy answers on Google suggests I'm missing something important here. If anyone wants to suggest a method for doing this in WPF as well, I'm curious to hear it. Thanks

  • Micrsoft Silverlight 3 cannot create service reference to localhost:port

    - by Monte
    Windows Server 2003 (IIS 6) Visual Studio 2008 .NET FrameWork 3.5 SP1 I am a .NET developer for a living and I have over 40 hours in the problem Project type = "Silverlight Navigation Application", "APS.NET Web Site" (when I tried it as "ASP.NET Web Application Project" I could not copy it to the production web site - well I could copy it but I could not make it run) Created a service.cs on the .Web side of the application. Created a reference to that service.cs on the Silverlight side. For a time all is good as I can reference the service as localhost:port (e.g. localhost:1374) in Visual Studio and debug both Silverlight side and service.cs To access the application in production mode (from IE) I update the service refrence and replace localhost:port with the IP address. The problem with the IP address is I cannot debug the service.cs so I have to change it back to localhost:port to debug. Now to the problem. After a period of time localhost:port just plain breaks. I get an error message no service at the other end Yes I know the port can change - that is not the problem - the port on the service side just plain breaks! For example from Visual Studio from the Silverlight side of the project right click "Service Reference", "Add Service Reverence". It finds 1 service in the application on a port. But when I click that service under "Services:" in the modal dialog box "Add Service Reference" I get an error: There was an error downloading 'http://localhost:1377/SehaleCSS.Web/Service.svc'. The request failed with the error message: -- Could not load file or assembly 'App_Web_tipnndfq, If I go back to the IP address the service is repsponding (with the right answer) The service just plain goes a while responding to localhost:port and then fails Even making NO change to service.cs it go a while then fails as a localhost:port It is not IIS environmental as I can go back to a prior saved version of the code and it works Something is happening that the .web side of the application is failing. It still works as an IP and it still exposes itself as a localhost:port but it fails to properly repsonde as a localhost:port.

  • how to create a backup of a file once the current one is changed using php

    - by SkyLar
    I'm playing around with file info in php and i'm wondering if its possible to do the following: once a file is changed get the contents of the file, then put the contents of the file into another file. kinda like a "backup system" so once you make a change to the file a duplicate one is created, each change to the original file overwrites the duplicate one. i'm trying to do this with storing the time in the db, is this possible? i don't know what there is to test against? more clearly, i would like to do the following: execute a script once a specifeced file is changed on the server

  • Attempt to create nested for loops generating missing arguments error

    - by JerryK
    Am attempting to teach myself to program using Tcl. (I want to become more familiar with the language to understand someone else's code - SCID chess) The task i've set myself to motivate my learing of Tcl is to solve the 8 queens problem. My approach to creating a program is to sucessively 'prototype' a solution. So. I'm up to nesting a for loop holding the q pos on row 2 inside the for loop holding the q pos on row 1 Here is my code set allowd 1 set notallowd 0 for {set r1p 1} {$r1p <= 8} {incr r1p } { puts "1st row q placed at $r1p" ;# re-initialize r2 'free for q placemnt' array after every change of r1 q pos: for {set i 1 } {$i <= 8} {incr i} { set r2($i) $allowd } for { set r2($r1p) $notallowd ; set r2([eval $r1p-1]) $notallowd ; set r2([eval $r1p+1]) $notallowd ; set r2p 1} {$r2p <= 8} { incr r2p ;# end of 'next' arg of r2 forloop } ;# commnd arg of r2 forloop placed below: {puts "2nd row q placed at $r2p" } } My problem is that when i run the code the interpreter is aborting with the fatal error: "wrong #args should be for start test next command. I've gone over my code a few times and can't see that i've missed any of the for loop arguments.

  • How to create AppStore.com short link?

    - by acidic
    For my resume, I am attempting to add a shortened link to the app that I created. I looked around and found that apple provides a link shortener for iOS apps using the AppStore.com URL. Unfortunately, since my app contains the ² character, I cannot figure out how to link to my app. The long link for my app is: https://itunes.apple.com/us/app/squared2/id498133871?mt=8 Also, is there a way to link to an app without having iTunes automatically open (only show the iTunes preview page)?

  • c# Create a unique name with a GUID

    - by Dave Rook
    I am creating a back up solution. I doubt there is anything new in what I'm trying to achieve. Before copying the file I want to take a backup of the destination file in case anything becomes corrupt. This means renaming the file. I have to be careful when renaming in case the file already exists and adding a 01 to the end is not safe. My question is, based upon not finding the answer else where, would adding a GUID to the file name work. So, if my file was called file01.txt, renaming the file to file01.txtGUID (where GUID is the generated GUID), I could then perform my back up of that file (at this instance having 2 back ups) and then, after ensuring the file has copied (by comparing length of file to the source), delete the file with the GUID in the name. I know the GUID is not 100% guaranteed to be unique but would this suffice?

    I have an edit view in my app which is a instance of UITableViewController and contains one cell with a textfield in a grouped table. At the moment this cell is at the top of the screen and is firstResponder so they keyboard is visible as well. But in all the Apples apps like the Contacts App when you edit a piece of information like an Email it buts both of its rows in the middle between the Nav Bar and the Keyboard not at the top of the screen. How do I achieve this effect? Many Thanks

  • rbind.zoo doesn't seem create consistent zoo object

    - by a-or-b
    I want to rbind.zoo two zoo object together. When I was testing I came across the following issue(?)... Note: The below is an example, there is clearly no point to it apart from being illustrative. I have an zoo object, call it, 'X'. I want to break it into two parts and then rbind.zoo them together. When I compare it to the original object then all.equal gives differences. It appears that the '$class' attribute differs, but I can't see how or why. Is I make these xts objects then the all.equal works as expected. i.e. ..... X.date <- as.POSIXct(paste("2003-", rep(1:4, 4:1), "-", sample(1:28, 10, replace = TRUE), sep = "")) X <- zoo(matrix(rnorm(24), ncol = 2), X.date) a <- X[c(1:3), ] # first 3 elements b <- X[c(4:6), ] # second 3 elements c <- rbind.zoo(a, b) # rbind into an object of 6 elements d <- X[c(1:6), ] # all 6 elements all.equal(c, d) # are they equal? ~~~~ all.equal gives me the following difference: "Attributes: < Component 3: Attributes: < Length mismatch: comparison on first 1 components "
