line-numbers

I'm creating a text editor for a domain specific language. I'm using the WPF RichTextBox as the basic control. I don't know how to gracefully include line numbering. Does anyone know of any examples? AvalonEdit is a good one, and it's open source. I think it has nearly all of the features of the Aqistar control such as syntax highlighting and folding. Ease to configure and use. Further details can be found here . I would create a composite control, with a stack panel control and text blocks on the left which you would use to handle the line numbering. If you are concerned with the number of

I have a Multiline richtextbox control into which i want to integrate the feature of adding a line number. i have considered many approaches Add a label and updating the line numbers as the line count changes Add a picturebox along with to draw string on it. Add another textbox along with and show line numbers on it Add listbox along and display line numbers in it. I got two doubts. The richtextbox which i'm using is a custom made control and derieves from RichTextBox class. How can i add multiple controls to it. What is the best approach to show line numbers for the multiline text in c# My

Though I've never heard of this but, is it possible to retrieve a node from the DOM using JS, and then find out on what line of the file that node occurred on? I'm open to anything, alternative browsers plugins/add-ons etc...it doesn't need to be cross-browser per say. I would assume that this would be possible somehow considering that some JS debuggers are capable of finding the line number within a script tag, but I'm not entirely sure. Ok, forgive me for how large this is. I thought this was a very interesting question but while playing with it, I quickly realized that innerHTML and its ilk

When you write something in BASIC, you are required to use line numbers. Like: 10 PRINT "HOME" 20 PRINT "SWEET" 30 GOTO 10 But I wonder: who came up with the idea to use line numbers at all? It is such a nuisance, and left quite an "echo" in the developing (pun intended) world! The idea back then was that you could easily add code everywhere in your program by using the appropriate line number. That's why everybody uses line numbers 10, 20, 30.. so there is room left: 10 PRINT "HOME" 20 PRINT "SWEET" 30 GOTO 10 25 PRINT "HOME" On the first interfaces BASIC was available for, there was no shiny

I have a file with 15 million lines (will not fit in memory). I also have a small vector of line numbers - the lines that I want to extract. How can I read-out the lines in one pass? I was hoping for a C function that does it on one pass. The trick is to use connection AND open it before read.table : con<-file('filename') open(con) read.table(con,skip=5,nrow=1) #6-th line read.table(con,skip=20,nrow=1) #27-th line ... close(con) You may also try scan , it is faster and gives more control.

When I do a git diff or a git log -p , how do I get line numbers of the source file(s) inlined with the output? I tried to look it up man git-diff | grep "line numbers" and I tried googling but got nothing quickly. You can't get human-readable line numbers with git diff There aren't currently any options to get line-numbers displayed vertically on the side with git diff . Unified-diff format That information is available in the (c)hunk headers for each change in the diff though, it's just in unified-diff format : @@ -start,count +start,count @@ The original state of the file is represented

I can :set number from within a file I'm editing but how can I have them always be on by default? Tim Pote Add set number to your .vimrc file in your home directory. If the .vimrc file is not in your home directory create one with vim .vimrc and add the commands you want at open. Here's a site that explains the vimrc and how to use it. abe312 To change the default setting to display line numbers in vi/vim: vi ~/.vimrc then add the following line to the file: set number Either we can source ~/.vimrc or save and quit by :wq , now vim session will have numbering :) sagar mahajan Terminal > su >
