• PDF text search and split library

  - by Horace Ho

  I am look for a server side PDF library (or command line tool) which can: split a multi-page PDF file into individual PDF files, based on a search result of the PDF file content Examples: Search "Page ???" pattern in text and split the big PDF into 001.pdf, 002,pdf, ... ???.pdf A server program will scan the PDF, look for the search pattern, save the page(s) which match the patten, and save the file in the disk. It will be nice with integration with PHP / Ruby. Command line tool is also acceptable. It will be a server side (linux or win32) batch processing tool. GUI/login is not supported. i18n support will be nice but no required. Thanks~

• Error with default argument in Source.getLines (Scala 2.8.0 RC1)

  - by Derek

  assuming I running Scala 2.8.0 RC1, the following scala code should print out the content of the file "c:/hello.txt" for ( line<-Source.fromPath( "c:/hello.txt" ).getLines ) println( line ) However, when I run it, I get the following error <console>:10: error: missing arguments for method getLines in class Source; follow this method with `_' if you want to treat it as a partially applied function Error occured in an application involving default arguments. val it = Source.fromPath("c:/hello.scala").getLines From what I understand, Scala should use the default argument "compat.Platform.EOL" for "getLines". I am wondering if I did wrong or is it a bug in scala 2.8 Thanks

• PHP getopt Operations

  - by Rachel

  This question is regarding getopt function in php. I need to pass two parameter to the php scripts like php script.php -f filename -t filetype Now depending upon the file type which can be u, c or s I need to do proper operation. I am using switch case for the same: Here is the Code I am using: // Get filename of input file when executing through command line. $file = getopt("f:t:"); Switch case should compare the type of the file which I am passing in from the command line (u, c or i) and accordingly match it and do the operation. switch("I am not sure what should go in there and this is wrong,Please advice") { case `Not sure`: $p->ini(); break; case `Not sure`: $p->iniCon(); break; case `Not sure`: $p->iniImp(); break; } Kindly advise on this !!!

• Form.ShowDialog() does not show form.

  - by clawson

  I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog() but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong. When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it. Any idea what may cause this to happen, or what I should be looking for that might be causing the problem?? Thanks for the help!

• Consistency vs Design Guidelines

  - by Adrian Faciu

  Lets say that you get involved in the development of a large project that is already in development for a long period ( more than one year ). The projects follows some of the current design guidelines, but also has a few different, that are currently discouraged ( mostly at naming guidelines ). Supposing that you can't/aren't allowed to change the whole project: What should be more important, consistency, follow the existing ones and defy current guidelines or the usage of the guidelines, creating differences between modules of the same project ? Thanks.

• Can't get InputStream read to block...

  - by mark dufresne

  I would like the input stream read to block instead of reading end of stream (-1). Is there a way to configure the stream to do this? Here's my Servlet code: PrintWriter out = response.getWriter(); BufferedReader in = request.getReader(); try { String line; int loop = 0; while (loop < 20) { line = in.readLine(); lgr.log(Level.INFO, line); out.println("<" + loop + "html>"); Thread.sleep(1000); loop++; // } } catch (InterruptedException ex) { lgr.log(Level.SEVERE, null, ex); } finally { out.close(); } Here's my Midlet code: private HttpConnection conn; InputStream is; OutputStream os; private boolean exit = false; public void run() { String url = "http://localhost:8080/WebApplication2/NewServlet"; try { conn = (HttpConnection) Connector.open(url); is = conn.openInputStream(); os = conn.openOutputStream(); StringBuffer sb = new StringBuffer(); int c; while (!exit) { os.write("<html>\n".getBytes()); while ((c = is.read()) != -1) { sb.append((char) c); } System.out.println(sb.toString()); sb.delete(0, sb.length() - 1); try { Thread.sleep(1000); } catch (InterruptedException ex) { ex.printStackTrace(); } } os.close(); is.close(); conn.close(); } catch (IOException ex) { ex.printStackTrace(); } } I've tried InputStream.read, but it doesn't block either, it returns -1 as well. I'm trying to keep the I/O streams on either side alive. I want the servlet to wait for input, process the input, then send back a response. In the code above it should do this 20 times. thanks for any help

• Ruby Thread with "watchdog"

  - by Sergio Campamá

  I'm implementing a ruby server for handling sockets being created from GPRS modules. The thing is that when the module powers down, there's no indication that the socket closed. I'm doing threads to handle multiple sockets with the same server. What I'm asking is this: Is there a way to use a timer inside a thread, reset it after every socket input, and that if it hits the timeout, closes the thread? Where can I find more information about this? EDIT: Code example that doesn't detect the socket closing require 'socket' server = TCPServer.open(41000) loop do Thread.start(server.accept) do |client| puts "Client connected" begin loop do line = client.readline open('log.txt', 'a') { |f| f.puts line.strip } end rescue puts "Client disconnected" end end end

• How can you make an emacs macro wait for cscope query results?

  - by Sudhanshu

  I am trying to write a macro which calls cscope-find-functions-calling-this-function on each and every tag in a file displayed in the *Tags List* buffer (created by list-tags command). This should create a buffer which contains list of all functions calling a set of functions defined in a certain file. This is the sequence of keystrokes: 1. <f11> ;; cscope-find-functions-calling-this-function 2. RET ;; newline [shows results of cscope in a split window] 3. C-x C-p ;; mark-page 4. C-x C-x ;; icicle-exchange-point-and-mark 5. <up> ;; previous-line 6. <end> ;; end-of-line [region to copy has been marked] 7. <f7> ;; append-results-to-buffer 8. C-x ESC O ;; [move back to split window on the right] 9. C-x b ;; icicle-buffer [Switch back to *Tags List* buffer] 10. *Tags ;; self-insert-command * 5 11. SPC ;; self-insert-command 12. List* ;; self-insert-command * 5 13. RET ;; newline 14 . <down> ;; next-line [Position point on next tag in the list] Problem: I get no results in the buffer, and I found out that's because Step 3-7 execute even before cscope prints the results of query made on Steps 1-2. I can insert a pause in the macro by using C-x q, but I'd rather like the macro to wait after Step 2, until cscope has returned with the results and only then continue further. I suspect this is not possible through a macro, maybe a LISP function... I'm not a lisp expert myself. Can someone please help? Thanks! Details: I have Icicles installed so by default I get word at point in current buffer as input in minibuffer. F11 is bound to cscope-find-functions-calling-this-function windmove is installed and C-x (C-x ESC o - as shown below) takes you to the right window. F7 is bound to append-results-to-buffer which is defined as: (defun append-results-to-buffer () (interactive) (append-to-buffer (get-buffer-create "c1") (point) (mark))) This function just appends the currently marked region to a buffer named "c1".

• Vim: Pasting from clipboard and automatically toggling :set paste

  - by Jonatan Littke

  Hey. When I paste things from the clipboard, they're normally (always) multilined, and in those cases (and those cases only), I'd like :set paste to be triggered, since otherwise the tabbing will increase with each line (you've all seen it!). Though the problem with :set paste is that it doesn't behave well with set smartindent, causing the cursor to jump to the beginning of a new line instead of at the correct indent. So I'd like to enable it for this instance only. I'm using Mac, sshing to a Debian machine with vim, and thus pasting in Insert mode using cmd-v. Cheers.

• Selecting an element based on class and id in jquery - similar to an SQL query

  - by Ankur

  I want to select an element based on it's class and id, I have seen many similar questions on SO. Most of the users ask why would you ever want to do this - which is not very helpful, trust me, this is the simplest way of solving my UI problem, and it's a very unique and intereting UI related to making generic triple stores easily browsable. At the moment the jQUery looks like this: $(document).ready( function() { $(".predicates").hide(); $(".objects").hide(); $("#subject").click( function() { $("#predId, .predicates").toggle(); // this line } ); $("#predId").click( function() { $("#objId, .objects").toggle(); } ); }); The line I am really interested in is this $("#predId, .predicates").toggle(); how do I get the select to ensure that both #predId and .predicates are true, at the moment it seems that only one or the other has to be true. Is there something like an && operator?

• How to make Inno Setup ignore the hidden attribute while searching for files?

  - by andi

  I have to copy into the installer folders containing hidden files (in my case Desktop.ini). I use a line similar to this one in the [Files] section: Source: "folder\*desktop.ini"; DestDir: "{app}\folder"; Flags: recursesubdirs uninsneveruninstall; Attribs: hidden This line only works if I remove the hidden attributes. If all are hidden, it complains that it could not find any files. How can I configure Inno to search for hidden files using patterns?

• java runtime tracing library to replace system.out.println

  - by Grzegorz Oledzki

  Have you heard of any library which would allow me to set up a tracing for specific methods at runtime? Instead of adding (and removing) lots of System.out.println in my code (and having to re-compile and re-deploy) I would like to have a magic thing which would print out a line for each call of selected method without any change in the code. This would work without re-compiling, so some kind of JVM agent (or some non-standard JVM would be needed?). Sounds like a job for aspect programming? A typical scenario would be to start an application, configure the traced methods dynamically (in a separate file or similar) and then everytime a selected method is called a line with its name (and arguments) is printed out to System.out (or some log file). Naturally one could think of tens of additional features, but this basic set would be a great tool. BTW, I use Eclipse interactive debugger too, not only the System.out tracing technique, but both have some advantages and sometimes Eclipse is not enough.

• How to overwrite specific lines on text files

  - by iTayb

  I have two text files. I'd like to copy a specific part in the first text file and replace it with a part of the second text file. This is how I read the files: List<string> PrevEp = File.ReadAllLines(string.Format(@"{0}naruto{1}.ass", url, PrevEpNum)).ToList(); List<string> Ep = File.ReadAllLines(string.Format(@"{0}naruto{1}.ass", url, EpNum)).ToList(); The part in PrevEp that I need: from the start until it meets a line that includes Creditw,,0000,0000,0000. The part I would like to overwrite in Ep: from the start to a line which is exactly Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text. I'm not so sure how may I do it. Could you lend me a hand? Thank you very much, gentlemen.

• C# ASP.Net The type or namespace name 'iAnywhere' could not be found

  - by Louis Russell

  Morning all, I know that this sounds like a simple referencing problem from the title this is becoming a nightmare! I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section. Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?) The line that the Error points to this line in the class: using iAnywhere.Data.AsaClient; I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be brilliant!

• measure rendered html in javascript without affecting the measurement

  - by drawnonward

  I am doing pagination in javascript. This is typographic pagination, not chopping up database results. For the most part it works, but I have run into a heisenberg issue where I cannot quite measure text without affecting it. I am not trying to measure text before it is rendered. I want the actual position it shows up at on screen, so I can paginate to where it is naturally wrapped. I am measuring the vertical position of characters, not the horizontal width of strings. The way I do this is similar to this answer in that I am applying a style to a block of text, then measuring the position of the newly created span. If the span does not reach the end of the page, I clear it and make a new span in a linear search. The problem is that the anti-aliased sub-pixel text layout is different when the span is applied. In rare cases, this causes the text to wrap differently when I measure it. I have only seen this when wrapping at a hyphen, and I assume it would not happen when wrapping at white space. As a concrete example, "prepared-he" is the string I am having trouble with. When I measure up to "prepare" it appears, as expected, to be within the current page. When I measure "prepared" the whole phrase wraps down to the next line, moving it to the next page, so it looks like the "d" is the character to break at. I break the text between "prepare" and "d-he" and that is wrong. Trying to evaluate individual characters opens a whole can of worms I would rather avoid. The wrapping changes because, with the new span, the line is 1 pixel wider. A solution to my problem could either be a better way to measure text using javascript, or a way to wrap text in a new element without affecting layout. I have tried setting margin-right:-1px for the class of the span being created to wrap the text. This had no noticeable effect. I am doing this in a UIWebView on the iPhone. There are some measurement related calls that are available in normal WebKit that are not available here. For example, Range does not have getBoundingClientRect or support setting an offset other than 0 in setStart or setEnd. Thank you
