• Portable way to determine the platform's line separator

  - by Adrian McCarthy

  Different platforms use different line separator schemes (LF, CR-LF, CR, NEL, Unicode LINE SEPARATOR, etc.). C++ (and C) make a lot of this transparent to most programs, by converting '\n' to and from the target platform's native new line encoding. But if your program needs to determine the actual byte sequence used, how could you do it portably? The best method I've come up with is: Write a temporary file in text mode with just '\n' in it, letting the run-time do the translation. Read back the temporary file in binary mode to see the actual bytes. That feels kludgy. Is there a way to do it without temporary files? I tried stringstreams instead, but the run-time doesn't actually translate '\n' in that context (which makes sense). Does the run-time expose this information in some other way?

• Shortest distance between two line segments

  - by Frank

  I need a function to find the shortest distance between two line segments. A line segment is defined by two endpoints. So for example one of my line segments (AB) would be defined by the two points A (x1,y1) and B (x2,y2) and the other (CD) would be defined by the two points C (x1,y1) and D (x2,y2). Feel free to write the solution in any language you want and I can translate it into javascript. Please keep in mind my geometry skills are pretty rusty. I have already seen http://stochastix.wordpress.com/2008/12/28/distance-between-two-lines/ and I am not sure how to translate this into a function. Thank you so much for help.

• New line or Carraige Return syntax problems

  - by Smoka

  Im pretty new to coding, heres my problem. Results->Text = "G55 > Y" + System::Convert::ToString(destY); "Results" is a System.Windows.Forms.Textbox "multiline btw", or so says VS. That line works fine, but i need a "new line or CR" at the end, so that i can repeat that line with different Literals and a different var in ToString. For days now ive tried different syntax's ive read about, and i cant get it to take any of them. Or even a complete different way to input text into Results-Text that would allow for tidy multiline use. Sidenote: since im using -Text and System::Convert::ToString in VC, would this code be considered just c++ or .net or CLI? to tighten my searches.

• preg_replace only replaces first occurrence then skips to next line

  - by Dom

  Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced. What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content: $resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content); Does anyone know a solution for why it only replaces the first match per line?

• How to deal with the new line character in the Silverlight TextBox

  - by Ian Oakes

  When using a multi-line TextBox (AcceptsReturn="True") in Silverlight, line feeds are recorded as \r rather than \r\n. This is causing problems when the data is persisted and later exported to another format to be read by a Windows application. I was thinking of using a regular expression to replace any single \r characters with a \r\n, but I suck at regex's and couldn't get it to work. Because there may be a mixture of line endings just blindy replacing all \r with \r\n doesn't cut it. So two questions really... If regex is the way to go what's the correct pattern? Is there a way to get Silverlight to respect it's own Environment.NewLine character in TextBox's and have it insert \r\n rather just a single \r?

• Store code line in a string?

  - by user1342164

  I need to store code in a string so that if a value is true, it is in the code line if not true its not in the code line. When I populate summarytextbox if consulting amount is "" then dont use this code if is does have an amount include the code. Is this possible? Other wise I would have to do a bunch if then statements. When I do the following below it cant convert to double. Dim ConsultingFee As String Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Session("ConsultingFeeAmount") = "" Then Else 'Store the following line in a string???? ConsultingFee = +Environment.NewLine + Session("ConsultingFee") + " Amount: " + Session("ConsultingFeeAmount") End If SummaryTextBox.Text = Session("TeachingHospital") + Environment.NewLine + Session("HospitalAddress") + Environment.NewLine + Session("HospitalCity") + Environment.NewLine + Session("HospitalState") + Environment.NewLine + Session("HospitalZip") + Environment.NewLine + Session("HospitalTIN") + ConsultingFee End Sub

• Doctrine: textarea line breaks & nl2br

  - by Tom

  Hi, I'm pulling my hair out with something that should be very simple: getting line breaks to show up properly in text that's returned from the database with Doctrine 1.2 I'm saving a message: $body = [text from a form textarea]; $m = new Message(); $m->setSubject($subject); $m->setBody($body); $m->save(); Querying the message: $q = Doctrine_Query::create() ->from('Message m') ->where('m.message_id = ?', $id) ->limit(1); $this->message = $q->execute(array(), Doctrine_Core::HYDRATE_ARRAY); In my template: echo $message[0]['body'] ... outputs the text without line breaks echo ln2br($message[0]['body']) ... no difference ... and I've tried every combination I could think of. Is Doctrine doing something to line breaks that's affecting this, or is there something that I'm just missing? Any help would be appreciated. Thanks.

• Is file_get_contents multi line?

  - by Abs

  Hello all, Does file_get_contents maintain line breaks? I thought it did but I have tried this: if($conn){ $tsql = file_get_contents('scripts/CreateTables/SLR05_MATCH_CREATETABLES.sql'); $row = sqlsrv_query($conn, $tsql); print_r(sqlsrv_errors()); } The errors I get is that SQL Server complains that there is incorrect syntax. I get the same errors when I run the SQL Script without any line breaks, which suggests file_get_contents removes them? When I run the script normally (open the file in SQL Server Management Studio) and execute it, it works perfectly. So is there something that I can use that maintains line breaks etc? Or is there another problem here in using queries from a file with the SQL Server PHP Driver from Microsoft? Thanks all for any help

• Small line-height cross-browser difference

  - by AESM

  So basicly my problem is that the line-heights in Firefox are a little bittle "larger" than in other browsers even though they're all fixed line-heights. For example, you have a block element which has a height from 100px and the line-height is set to 102px. Now, in Firefox the vertical alignment of text is perfect. But in the latest Chrome and Safari 4, the text stands 2px or so higher. Isn't there any way to fix this? Thanks.

  Hello, Suppose I have this html markup: <div id="wrapper"> $(function(){ // hide all links except for the first $('ul.child:not(:first)').hide(); $("a.slide:first").css("background-color","#FF9900"); $('ul.parent a.slide').click(function(){ $('ul.parent a.slide').css("background-color","#3399FF"); $('ul.parent a.slide').mouseout(function(){ $(this).css("background-color","#3399FF"); }); $('ul.parent a.slide').mouseover(function(){ $(this).css("background-color","#66CC66"); }); }); }); </div> What is the easiest way to read each line of code present in the div. How do I extract each line of code from that div or loop over each line styling in any way I want. Thanks

• Vertical line problem in the detail section of Crystal report

  - by nav100

  Hello, I have a little problem with the vertical lines in Detail section. In detail section at the end there is horizontal line. Also I have Report Footer section which displays total number of records. I suppressed Page Footer section. I would like end all the vertical lines to the last line of the records not to extend beyond the "Total"(Report Footer). It works fine if everything on the same page. The problem starts when the last line of the detail is on the first page and the "Total" wouldn't fit on the first page. It displays "Total" on the second page and it draws vertical lines to the end of the page. Thanks for any suggestion.

• Importing CSV with line breaks in Excel 2007

  - by ph0enix

  I'm working on a feature to export search results to a CSV file to be opened in Excel. One of the fields is a free-text field, which may contain line breaks, commas, quotations, etc. In order to counteract this, I have wrapped the field in double quotes ("). However, when I import the data into Excel 2007, set the appropriate delimiter, and set the text qualifier to double quote, the line breaks are still creating new records at the line breaks, where I would expect to see the entire text field in a single cell. I've also tried replacing CR/LF (\r\n) with just CR (\r), and again with just LF (\n), but no luck. Has anyone else encountered this behavior, and if so, how did you fix it? TIA, -J

• Drawing a 2D line on a canvas

  - by Jason94

  I have the datalist = 62, 76, 80, 72, 71, 75, 77 that i want to present as a 2D line drawed point to point. In my Wpf application i have a canvas with the height: 173 and width: 455. How do i go about it and draw a line by my datalist and use almost the whole height of the canvas? as it is now the data is just represented on a line at the bottom at the canvas, not using (and therefor giving a bad representation of the data) whole heigh of the canvas. It would also be nice to place it in the center of the box too...

• Jump-To-Code-Line Eclipse Shortcuts

  - by scrr

  Hello, is it possible, in Eclipse, to mark certain lines with Shortcuts and be able to quickly jump to those lines? Example: Let's say I have maintenanceHeavyMethod() at line 120 in my class, gameLoop() at line 800 and some listener at line 1460. I'd like to f.ex. press CTRL-SHIFT-1, 2, 3 etc. to mark those positions, and then use f.ex. CTRL-1, 2, 3 to immediately jump to them. I don't like split-screens etc, but I need to jump around when writing. Is there such a feature? I'm using latest Eclipse to write Java-programs.

• Clojure: using *command-line-args* in the script rather than REPL

  - by Teflon Mac

  I've clojure running within Eclipse. I want to pass arguments to clojure when running it. In the below the arguments are available in the REPL but not in the script itself. What do I need to do such that in the below typing arg1 in the REPL will return the first argument? Script: (NS Test) (def arg1 (nth *command-line-args* 0)) After clicking on the Eclipse "Run"... Clojure 1.1.0 1:1 user=> #<Namespace test> 1:2 test=> arg1 nil 1:3 test=> *command-line-args* ("bird" "dog" "cat" "pig") 1:4 test=> (def arg2 (nth *command-line-args* 1)) #'test/arg2 1:5 test=> arg2 "dog" 1:6 test=>

• How to access the calling source line from interactive shell

  - by TJD

  I want to make a function that can determine the source code of how it was called. I'm aware of how to do this generally with the inspect module. For example, this question, works well and provides my desired output in the lines variable as shown below: def hello(x): frame,filename,line_number,function_name,lines,index=\ inspect.getouterframes(inspect.currentframe())[1] print(frame,filename,line_number,function_name,lines,index) The problem is that this solution doesn't work in an interactive command line session. For example, from a command line, the result looks like: >>> y = hello(7) (<frame object at 0x01ECA9E8>, '<stdin>', 1, '<module>', None, None) The problem is that the source file is '<stdin>', so the lines variable is None. How can I access the calling line to find the result containing the string y = hello(7) during an interactive session?

• Cross vertion line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• Execute a line in a text file

  - by apophis

  Hi I have a program that reads text files filled with code designed to be executed line by line by the program, like a script file. The problem is that I don't no how to do the line executing part. Here is my code, I thought using the \r would fool the console. But it just shows me a list of lines in the file. if (tok[0] == "read" && length == 2) { try { StreamReader tr = new StreamReader(@"C:\Users\Public\"+tok[1]+".txt"); while (!tr.EndOfStream) { Console.WriteLine(tr.ReadLine()); } } catch { Console.WriteLine("No such text file.\n"); } Prompt(); If I knew what to search for to fix my problem in Google, I would have. But I've got no idea. Thanks

• index was outside the bounds of the array because of \n (new line) in richTextBox

  - by revvs

  If i go into the next line with richTextBox1.Text + "\n" you can't use richTextBox with anything anymore normally. Why not ? because index will be outside the bounds of the array and you won't be able to transport the data into database or work with it normally...it will be all messed up. It is like the story with cin and getline in C++, but much worse. Here you won't see errors, not until you'll try to transport it into database. If you use "\n" to write new lines into txt, your txt will be also unusable. It will look like up to the byte the same as if you would write it by hand same sentences but "\n" will fuck it up. So how do i go into the next line and not have this "\n" screwing up my program ??! How do i go into the new line ?

• New line before header()

  - by MetalAdam

  I'm working with a custom made Joomla script that generates an image from a blob in a database. However, when we moved it from an Apache server to an IIS server, the script is breaking. Upon investigation, it seems that now, there is a line break that is getting appended before the header function is being run (when I comment out the image portion, and do an echo "test";, test gets printed on line 2 of the source code. I've gone through the script over and over again, and through the many files in the component, and can't seem to find out where this new line is coming from. At all. I've tried using ob_start() and many similar functions, but nothing seems to work. I'm completely out of ideas, and don't know where to turn. Is there a way to trace what files are being called in the page, perhaps? Any thoughts on further steps?

• wrap all lines that are longer than line length

  - by user1919840

  I am writing a program that limits each line to a certain length. this is what i got so far, i am almost done but i still need to cut each line, but i cant figure it out. def main(): filename = input("Please enter the name of the file to be used: ") openFile = open(filename, 'r+') file = openFile.read() lLength = int(input("enter a number between 10 & 20: ")) while (lLength < 10) or (lLength > 20) : print("Invalid input, please try again...") lLength = int(input("enter a number between 10 & 20: ")) wr = textwrap.TextWrapper() wraped = wr.wrap(file) print("Here is your output formated to a max of", lLength, "characters per line: ") wr.width = lLength wr.expand_tabs = True for lines in wraped: print(lines) an example of what the output SHOULD be is this. If the file specified contains this text: hgytuinghdt #here the length is 11 ughtnjuiknshfyth #here the length is 16 nmjhkaiolgytuhngjuin #here the length is 20 and the lLength is specified to 15 then this should print out: hgytuinghdt ughtnjuiknshfyt h nmjhkaiolgytuhng juin Thanks.
