  • noweb dpp filter and latex not printing curly braces

    - by Dervin Thunk
    Hello. Well, this smells like a tumbleweed, but I will ask it anyway. Suppose you have a noweb file with some c# code. You also have the c++ pretty-print filter dpp. If you run the command noweave -filter ./dpp -x test.nw > csharp.tex on the file below, it will print everything except for the curly braces. Instead of them, I get an em-dash and a closing quotations marks (i.e. ?) in the dvi. The tex source looks fine... Any ideas? @ C\# test file <<test.c>>= while( (a[right] >= pivot) && (left < right) ) { right--; }

  • casting raw strings python

    - by dave
    in python, given a variable which holds a string is there a quick way to cast that into another raw string variable? the following code should illustrate what im after... def checkEqual(x, y): print True if x==y else False line1 = "hurr..\n..durr" line2 = r"hurr..\n..durr" line3 = "%r"%line1 print "%s \n\n%s \n\n%s \n" % (line1, line2, line3) checkEqual(line2, line3) #outputs False checkEqual(line2, line3[1:-1]) #outputs True The closest I have found so far is the %r formatting flag which seems to return a raw string albeit within single quote marks. Is there any easier way to do this like a line3 = raw(line1) kind of thing?

  • Using pyodbc to insert rows into a MS Access MDB, how do I escape the paramaters?

    - by MDBGuy
    Hi, I'm using pyodbc to talk to a legacy Access 2000 .mdb file. I've got a cursor, and am trying to execute this: c.execute("INSERT INTO [Accounts] ([Name], [TypeID], [StatusID], [AccountCat], [id]) VALUES (?, ?, ?, ?, ?)", [u'test', 20, 10, 4, 2]) However, doing so results in pyodbc.Error: ('HYC00', '[HYC00] [Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented (106) (SQLBindParameter)') I understand I can simply change the question marks to the literal values, but in my experience proper escaping of strings across databases is... not pretty. PHP and mysql team up to bring mysql_real_escape_string and friends, but I can't seem to find pyodbc's function for escaping values. If you could let me know what the recommended way of inserting this data (from python) is, that'd be very helpful. Alternatively, if you have a python function to escape the odbc strings, that would also be great. Thanks for the help.

  • Problem with pgfplot label

    - by harper
    I want to draw an x-y-diagram with axis labels. Unfortunately the ylabel is misplaced. It looks as depending on the actual data. When the other data line in the sample below is used instead of the upper line, it looks better. How can I move the label to the left or (more desirable) how can I tell pgfplot to do it corectly? % !TEX TS-program = pdflatex % !TEX encoding = UTF-8 Unicode \documentclass{scrartcl} \usepackage[utf8]{inputenc} \usepackage{tikz} \usepackage{pgfplots} \begin{document} \begin{tikzpicture} \begin{axis}[width=13cm,height=8cm, xlabel={I in mA}, ylabel={U in mV}] \addplot[only marks,mark=star] coordinates { % (1.36, -0.0177) (45.38, 0.0273) (74.19, 0.0413) (100.88, 0.0533) (134.80, 0.0683) (195.27, 0.1073) }; \end{axis} \end{tikzpicture} \end{document}

  • Objective-C syntax

    - by mebFace
    I've been studying objective-c for a few days now. I keep coming across these two structures: NSString * somestring (NSString *) somestring I understand the first simply sets a pointer to an NSString object, but what does the second construct do, and when should I use it? What's the deal with the asterix marks? Sorry if this question doesn't make any sense, I am completely new to this language, and haven't even reached the level of asking proper questions. Main purpose -- I'm trying to decipher this method: -(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger) row forComponent: (NSInteger)component *Also, the classes I chose don't matter. *

  • pyODBC and Unicode Problem

    - by Aviv Giladi
    Hey guys, I'm working with pyODBC communicate with a MS SQL 2005 Express server. The table to which i'm trying to save the data consists of nvarchar columns. query = u"INSERT INTO tblPersons (name, birthday, gender) VALUES('" query = query + name + u"', '" query = query + birthday + u"', '" query = query + gender + u"')" cur.execute(query ) The variables name, birthrday and gende are read from an Excel file and they are Unicode strings. When I execute the query and either look at the table with SQL Server Management Studio or execute a query that fetches the data that was just inserted, all the data that was written in a non-English languages turn into question marks. The data that was written in English is preserved and appears in the table in the correct way. I tried adding CHARSET=UTF16 to my connection string, but had no luck with that. I can use UTF-8 which works fine but as a working convention, I need all the data saved in my DB to be UTF16. Thanks!

  • .NET PostSubmitter sends backslashes

    - by Stefan N.
    Hi, I'm using C# to send JSON to a PHP-Script, like this: string json = "{"; json += "\"prop\":\"some text\""; json += "}"; PostSubmitter post = new PostSubmitter(); post.Url = "http://localhost/synch/notein.php"; post.Type = PostSubmitter.PostTypeEnum.Post; post.PostItems.Add("note", json); post.Post(); Of course I'll have to escape the inner quotes, but they get sended to the script! To make things worse: There is text, which already has quotation marks, so those must be escaped to be valid JSON. In this case I want the backslashes to be transmitted. Any idea to accomplish this?

  • How can I extract URLs from plain text with Perl?

    - by Russell C.
    I need the Perl regex to parse plain text input and convert all links to valid HTML HREF links. I've tried 10 different versions I found on the web but none of them seen to work correctly. I also tested other solutions posted on StackOverflow, none of which seem to work. The correct solution should be able to find any URL in the plain text input and convert it to: <a href="$1">$1</a> Some cases other regular expressions I tried didn't handle correctly include: URLs at the end of a line which are followed by returns URLs that included question marks URLs that start with 'https' I'm hoping that another Perl guy out there will already have a regular expression they are using for this that they can share. Thanks in advance for your help!

  • Perl TDS character sets

    - by skiphoppy
    I'm using the FreeTDS driver with DBD::Sybase, connecting to an MS SQL Server. When I query certain values of certain records, I get this error: DBD::Sybase::st fetchrow_arrayref failed: OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (9) NUMBER = (99) Server , database Message String: WARNING! Some character(s) could not be converted into client's character set. Unconverted bytes were changed to question marks ('?'). This seems to happen for records that contain special Windows character-set characters, such as curly quotes, copied and pasted from people's Outlook and Word messages. Unfortunately, I do not have any control of this database; sanitizing the input on the way in is obviously the way to go, but is not available to me. What FreeTDS settings do I need to change to be able to successfully query these records?

  • Tricky string transformation (hopefully) in LINQ

    - by Larsenal
    I'm hoping for a concise way to perform the following transformation. I want to transform song lyrics. The input will look something like this: Verse 1 lyrics line 1 Verse 1 lyrics line 2 Verse 1 lyrics line 3 Verse 1 lyrics line 4 Verse 2 lyrics line 1 Verse 2 lyrics line 2 Verse 2 lyrics line 3 Verse 2 lyrics line 4 And I want to transform them so the first line of each verse is grouped together as in: Verse 1 lyrics line 1 Verse 2 lyrics line 1 Verse 1 lyrics line 2 Verse 2 lyrics line 2 Verse 1 lyrics line 3 Verse 2 lyrics line 3 Verse 1 lyrics line 4 Verse 2 lyrics line 4 Lyrics will obviously be unknown, but the blank line marks a division between verses in the input.

  • Using Parallel Extensions with ThreadStatic attribute. Could it leak memory?

    - by the-locster
    I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread locla storrage might be sensible to allow re-use of objects by worker threads. As such I was lookign at the ThreadStatic attribute which marks a static field/variable as having a unique value per thread. It seems to me that it would be unwise to use PE with the ThreadStatic attribute without any guarantee of thread re-use by PE. That is, if threads are created and destroyed to some degree would the variables (and thus objects they point to) remain in thread local storage for some indeterminate amount of time, thus causing a memory leak? Or perhaps the thread storage is tied to the threads and disposed of when the threads are disposed? But then you still potentially have threads in a pool that are longed lived and that accumulate thread local storage from various pieces of code the threads are used for. Is there a better approach to obtaining thread local storage with PE? Thankyou.

  • Sharepoint Designer Workflow with multiple tasks in sequence

    - by Triangle Man
    I have a multi-step Sharepoint workflow in task list A that starts when a new task is created in that list and creates a task in another list, B. When that task in list B is completed, I would like the workflow in list A to create another task in list C. I am using Sharepoint Designer 2007 to build all of this and at the moment I have this represented by multiple steps. So, step one is to create the task in the other list, and store its ID as a variable. Step 2 is conditional on a value in the task created by step one being marked complete, and it creates a task in the next list, and so on. However, when I run the workflow, it marks its status as complete as soon as the item in the first list is completed, and does not go on to create the task outlined in Step 2 of the workflow. I would like to know why the workflow is marking itself complete at the end of step one, and why the subsequent steps are not executed. Thanks in advance for your help.

  • Bad interpreter: No such file or directory

    - by user1497462
    I'm working through Michael Hartl's tutorial trying to learn Rails for the first time, and I've run into some issues. I recently reinstalled the whole Rails Installer because I had apparently inadvertently deleted some important files. Now, when I try running a test I get the following error: sh.exe": /c/Program Files (x86)/ruby-1.9.3/bin/bundle: "c:/Program: bad interpre ter: No such file or directory I checked my PATH and attempted to use the solution outlined here: Bundle command not found. Bad Interpreter ..but putting quotation marks around "C:\Program Files (x86)\ruby-1.9.3\bin" didn't do anything for me. I ran $ rails -v and got the following output: $ rails -v ?[31mCould not find multi_json-1.3.6 in any of the sources?[0m ?[33mRun `bundle install` to install missing gems.?[0m So then I tried running $bundle install and got the following issue again: Tom@TOM-PC /c/sample_app (updating-users) $ bundle install sh.exe": /c/Program Files (x86)/ruby-1.9.3/bin/bundle: "c:/Program: bad interpre ter: No such file or directory I'd really appreciate any help -- I've spent 5+ hours today trying to get back on track and am still at a loss.

  • sending mail using mutt + emacs

    - by lakshmipathi
    How to sent mail from emacs? I have add from address and subject and trapped inside emacs I found this There are two ways to send the message. C-c C-s (mail-send) sends the message and marks the mail buffer unmodified, but leaves that buffer selected so that you can modify the message (perhaps with new recipients) and send it again. C-c C-c (mail-send-and-exit) sends and then deletes the window or switches to another buffer But both ( ctrl+c ctrl+s ) and (ctrl-c crtl+c) are not working ps:Thought it's not programming related. it's programmer environment related question-hoping it won't be closed :)

  • Open Source Queuing Solutions for peek, mark as done and then remove

    - by user330114
    I am looking at open source queuing platforms that allow me do the following: I have multiple producers, multiple consumers putting data into a queue in a multithreaded environment with the specific use case: I want the ability for consumers to be able do the following Peek at a message from the queue(which should mark as the message as invisible on the queue so that other consumers cannot consume the same message) The consumer works on the message consumed and if it is able to do the work successfully, it marks the message as consumed which should permanently delete it from the queue. If the consumer dies abruptly after marking the message as consumed or fails to acknowledge successful consumption after a certain timeout, the message is made visible on the queue again so that another consumer can pick it up. I've been looking at RabbitMQ, hornetQ, ActiveMQ but I'm not sure I can get this functionality out of the box, any recommendations on a system that gives me this functionality?

  • Escape characters during paste in vim

    - by Michael Anderson
    I copy stuff from output buffers into C++ code I'm working on in vim. Often this output gets stuck into strings. And it'd be nice to be able to escape all the control characters automatically rather than going back and hand editing the pasted fragment. As an example I might copy something like this: error in file "foo.dat" And need to put it into something like this std::string expected_error = "error in file \"foo.dat\"" I'm thinking it might be possible to apply a replace function to the body of the last paste using the start and end marks of the last paste, but I'm not sure how to make it fly.

  • Text Editor For Flash?

    - by JasonS
    Hi, I work for a company which produces flash websites. The CMS is built in PHP. The client can update the text on the CMS site. Currently it uses a really old, bad, flash text-editor. It needs to be upgraded to something much much better. I need a text editor that will produce 'flash-html' as well as 'valid-html'. Or even something that marks up the text in the way that would allow me to do this. I tried using TinyMCE and ran into problems trying to convert the HTML. Has anyone tried doing this? Can anyone recommend anything or give any tips on how I can do this?

Can someone help?

  • How can I accept a hash mark in a URL via $_GET?

    - by bccarlso
    From what I have been able to understand, hash marks (#) aren't sent to the server, so it doesn't seem likely that I will be able to use raw PHP to parse data like in the URL below: index.php?name=Ben&address=101 S 10th St Suite #301 I'm looking to pre-populate form fields with this $_GET data. How would I do this with Javascript (or jQuery), and is there a fallback that wouldn't break my form for people not using Javascript? Currently if there is a hash (usually in the address field), everything after that is not parsed in or stored in $_GET.

  • Questions about linux root file system.

    - by smwikipedia
    I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My questions are: Where is this "big tree" located? Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

  • Disappearing Inlineshapes

    - by Rick
    I frequently edit files that have numerous inlineshapes, one per paragraph. One of the edits I make is to eliminate "double" paragraph marks either using Search and Replace or a simple macro that performs the same operation (e.g., search for "^p^p" and replace with "^p"). This operation works fine in Word 97-2003 documents (.doc), but when I try it on .docx documents, I lose all of the inlineshapes. The .docx files seem to ignore the inlineshape, therefore seeing the paragraphs containing them as "empty". Search and Replace sees "^p^p", replaces it with "^p", and the graphic goes away. Any thoughts on how to work around this?
