  • Using clang to analyze C++ code

    - by aneccodeal
    We want to do some fairly simple analysis of user's C++ code and then use that information to instrument their code (basically regen their code with a bit of instrumentation code) so that the user can run a dynamic analysis of their code and get stats on things like ranges of values of certain numeric types. clang should be able to handle enough C++ now to handle the kind of code our users would be throwing at it - and since clang's C++ coverage is continuously improving by the time we're done it'll be even better. So how does one go about using clang like this as a standalone parser? We're thinking we could just generate an AST and then walk it looking for objects of the classes we're interested in tracking. Would be interested in hearing from others who are using clang without LLVM.

  • How to render Asian characters in a PDF using xhtmlrenderer

    - by Mark Derricutt
    I was wondering what steps were needed to render Asian characters using the java based xhtmlrenderer (flying saucer) library? I am wanting to render the following: <html> <body>????????</body> </html> Without any font settings being added to the HTML this renders fine in normal browsers, but I can't find anyway to render this to PDF using the iTextRenderer portion of xhtmlrenderer. After following various threads on the mailing list, I see lots of posts talking about adding .TTF files from the c:\windows\fonts directory, and I have modified the examples to run on linux ( https://gist.github.com/643173745182c9becc57 ), which shows me various fonts being displayed, but I don't see any Asian glyffs. Does anyone have any decent pointers, or clean solutions to this problem? Or am I looking at the wrong problem with a really simple solution elsewhere?

  • PartCover shows 0% coverage for getter and 100% coverage for setter despite the code being commented

    - by Gorgsenegger
    Hi all, I have a public property in my code as below: [DependencyInjection] public IEVentController EventController { get; set; } I also have a line of code referencing the EventController property: EventController.ExecuteObjectEvents( someObject, null ); Now currently (due to some missing implementation in another part of the application) I commented both these code sections out. Nevertheless, when I run PartCover it shows me a coverage of 0% for get_EventController and 100% for set_EventController. The strange thing is, that the Coverage Details view also correctly shows me that the code is commented out and therefore should not be treated as code - why does PartCover recognise it anyway? I would have expected to not get the getter and setter listed in the PartCover result. There is definitely no other reference to that code in the class to be tested, any ideas? Thanks in advance & Best regards G.

  • Compact representation of GUID/UUID?

    - by chakrit
    I need to generate a GUID and save it via a string representation. The string representation should be as short as possible as it will be used as part of an already-long URL string. Right now, instead of using the normal abcd-efgh-... representation, I use the raw bytes generated and base64-encode them instead, which results in a somewhat shorter string. But is it possible to make it even shorter? I'm OK with losing some degree of uniqueness and keeping a counter, but scanning all existing keys is not an option. Suggestions?

  • XML to DOC to PDF

    - by Max
    what is the easiest(and fastest) way to perform this kind of transformation: "Data in XML" to "Some MS Word 2003 Supported format" to PDF using Java? My first guess was to fill the template with XML data (using Placeholders for example) and then save it and convert it to PDF. But I can't just put placeholders to DOC files, and I can't convert from some other Word formats to PDF... My primary task is to convert XML Data to PDF allowing users to change the PDF on-demand. The best way to change the PDF on-demand seems to give user some kind of MS Word readable document, and then convert it back. There are 2 main problems with this task: 1) I can't use OpenOffice for conversion. 2) System should be able to convert ~1 page of table-based document per 1 second on 2Ghz Core. 3) RTF does not provide enough styling, so some more complex format should be used. Thanks in advance.

  • Prawn html formatting

    I have some simple lists and bold/italic text to format with prawn. How do I get prawn to pay attention to the html tags instead of just displaying them explicitly. If prawn can't do this, what are my other options?

  • I want to merge two PostScript Documents, pagewise. How?

    - by Peter Miehle
    hello, i have a tricky question, so i need to describe my problem: i need to print 2-sided booklets (a third of a paper) on normal paper (german A4, but letter is okay also) and cut the paper afterwards. The Pages are in a Postscript Level 2 File (generated by an ancient printer driver, so no chance to patch that, except ps2ps) generated by me with the ancient OS's Printing driver facilities (GpiMove, GpiLine, GpiText etc). I do not want to throw away two-thirds of the paper, so my idea is: Take file one, two and three, merge them (how?) on new double-sided papers by translate/move file two and three by one resp. two thirds and print the resulting new pages. If it helps, I can manage to print one page of the booklet per file. I cannot "speak" postscript natively, but I am capable of parsing and merging and manipulating files programmaticly. Maybe you can hint me to a webpage. I've read through the manuals on adobe's site and followed the links on www.inkguides.com/postscript.asp Maybe there are techniques with PDF that would help? I can translate ps2pdf. Thanks for help Peter Miehle PS: my current solution: i.e. 8 pages: print page 1, 4 and 7 on page one, 2,5,8 on page two and 3,6,blank on page three, cut the paper and restack. But i want to use a electrical cutting machine, which works better with thicker stacks of paper.

  • x86 instruction encoding tables

    - by Cheery
    I'm in middle of rewriting my assembler. While at it I'm curious about implementing disassembly as well. I want to make it simple and compact, and there's concepts I can exploit while doing so. It is possible to determine rest of the x86 instruction encoding from opcode (maybe prefix bytes are required too, a bit). I know many people have written tables for doing it. I'm not interested about mnemonics but instruction encoding, because it is an actual hard problem there. For each opcode number I need to know: does this instruction contain modrm? how many immediate fields does this instruction have? what encoding does an immediate use? is the immediate in field an instruction pointer -relative address? what kind of registers does the modrm use for operand and register fields? sandpile.org has somewhat quite much what I'd need, but it's in format that isn't easy to parse. Before I start writing and validating those tables myself, I decided to write this question. Do you know about this kind of tables existing somewhere? In a form that doesn't require too much effort to parse.

  • How to pretend to be a Printer on iOS like the Apps Save2PDF or Adobe® CreatePDF?

    - by Lindemann
    I want to convert HTML to PDF on an iOS Device... ...but I dont want to load my HTML in a UIWebView, take a snapshot and generate an ugly PDF from this snapshot picture...because the text must be selectable for my purpose. I wonder how Apps like Save2PDF or Adobe® CreatePDF are able to converting multiple files into PDF and save them. I guess they don't generate the PDF's by their own, but get them from Apples Printing Framework. How does this Apps work?

  • Adding text over existing PDFs using reportlab

    - by Shane
    I'm interested in filling out existing PDF forms programatically. All I really need to do is pull information from user input and then place the appropriate text over an existing PDF in the appropriate locations. I can already do this with reportlab by feeding the same sheet of paper into a printer, twice, but this just really rubs me the wrong way. I'm tempted to just personally reverse engineer each existing PDF and draw every line and character myself before adding the user-inputted text, but I wanted to check to see if there was an easy way to take an existing PDF and set it as a background for some extra text. I'd really prefer to use python as it's the only language I feel comfortable with. I also realize that I could just scan the document itself and use the resulting raster image as a background, but I would prefer the precision of vector graphics. It seems like ReportLab has a commercial product with this functionality, and the specific function I'm looking for is in it (copyPages) - but it seems like overkill to pay for a 4 figure product for a single, simple function for a nonprofit use.

  • Need to merge multiple pdf's into a single PDF with Table Of Contents sections

    - by Jason
    Will have 50-100 single PDF's that we'll be generating with a php script. PDF's are generally grouped into groups of 10-20. Each group needs to have it's own Table of Contents or Index, and then there also needs to be a Master Table of Contents or Index at the beginning. Or if that is too difficult we could get away with a single Table of Contents at the beginning. What's the best way to go about this? Will we need to create the Table of Contents and then export that to PDF and append it to the beginning and mash the rest of the files after that? Or is there a better solution? And what's the best tool for us to merge the pdf's? Will be running on a Linux server.

  • Test assembly code on a mac

    - by happyCoding25
    Hello, A while back I was following some tutorials an assembly. I was running it all on a windows machine, compiling with NASM and then writing the compiled code to a floppy disk, then reboot and try the code. This process was long and time consuming and sadly was not on a mac. When I found out that Xcode for mac installed NASM I immediately tried to compile some code. The code compiled fine. The issue is testing it. On a mac I have no floppy (not like I want to use one) so Im not sure how to test this. I looked in to Q (kju) and found it would only emulate things on an ISO file. So I guess what Im asking is is it possible to install the compiled code on an ISO file for testing? (Note: the code when compiled forms a .bin file) Thanks for any help

  • wkhtmltopdf - cannot convert local file

    - by user522962
    I just downloaded version 10.0 for opensuse v. 11.3. I can convert a webpage (ie www.google.com) using it but cannot convert a local file. I grant all permissions on the file (& i've even tried running under sudo to no avail). This is the error: "Loading pages (1/6) Error: Failed loading page file:///file.html". The file exists but wkhtmltopdf refuses to load it. I even tried version 9.9 w/ the same result What am I missing?

  • PHP and C# communication on IIS7 (to generate dynamic PDF)

    - by David Murdoch
    Background: I couldn't find any decent free HTML to PDF conversion utilities in C#. There are 100s of them for PHP with extensive documentation, support, and CSS support. So I am using html2ps and html2pdf (php). I have PHP 5.2 installed on IIS7 and its working beautifully to create PDFs. I have the following in getPDF.aspx <!-- Output the header --> <DM:header runat="server" ID="header" /> <asp:Placeholder id="content" runat="server" /> <!-- Output the footer --> <DM:footer runat="server" ID="footer" /> and in getPDF.aspx.cs: protected void Page_Load(object sender, EventArgs e){ // AddContentControl simples adds a controls to the content Placeholder. AddContentControl("controls/page1.ascx"); AddContentControl("controls/page2.ascx"); AddContentControl("controls/page3.ascx"); } and in generatePDF.php: <?php /* ... includes and stuff here ... */ $data = "THE HTML GOES HERE!"; // creates the PDF from the $data and Outputs the created file. convert_to_pdf($data); ?> -- getPDF.aspx works perfectly...except the output is HTML. So how can I get getPDF.aspx to output its HTML as PDF generated by generatePDF.php?

  • Rails: creating a custom data type / creating a shorthand

    - by Shyam
    Hi, I am wondering how I could create a custom data type to use within the rake migration file. Example: if you would be creating a model, inside the migration file you can add columns. It could look like this: def self.up create_table :products do |t| t.column :name, :string t.timestamps end end I would like to know how to create something like this: t.column :name, :my_custom_data_type The reason for this to create for example a "currency" type, which is nothing more than a decimal with a precision of 8 and a scale of 2. Since I use only MySQL, the solution for this database is sufficient enough. Thank you for your feedback and comments!

  • Easiest way of unit testing C code with Python

    - by Jon Mills
    I've got a pile of C code that I'd like to unit test using Python's unittest library (in Windows), but I'm trying to work out the best way of interfacing the C code so that Python can execute it (and get the results back). Does anybody have any experience in the easiest way to do it? Some ideas include: Wrapping the code as a Python C extension using the Python API Wrap the C code using SWIG Add a DLL wrapper to the C code and load it into Python using ctypes Add a small XML-RPC server to the c-code and call it using xmlrpclib (yes, I know this seems a bit far-out!) Is there a canonical way of doing this? I'm going to be doing this quite a lot, with different C modules, so I'd like to find a way which is least effort.

  • Looking for a reporting tool that will allow vector graphics in output file (PDF)

    - by Richard West
    I have been tasked with evaluating our current system that we use for creating and outputing reports. Currently we are using Crystal Reports ver 8, (I know that this is and old version.), which has a custom commandline app that we wrote in C# to execute the report for a given parameter passed through the command line. We like Crystal becuase it's easy to setup and design the report. It's also easy to print and create a PDF file from crystal using our custom commandline program. One of the problems/complaints that we have is that Crystal does does not appear to have a method that will allow us to create a PDF file with a vector images, such as our company logo. Crystal Reports always converts an image into a bitmap. When the PDF is printed, the results are less than flattering, and the PDF file size is increased. Does anyone have any recomendadtions for a reporting product that we should consider?

  • How to recursively delete some xml elements using XSLT

    - by Monomachus
    Hi, So I got this situation which sucks. I have an XML like this <table border="1" cols="200 100pt 200"> <tr> <td>isbn</td> <td>title</td> <td>price</td> </tr> <tr> <td /> <td /> <td> <span type="champsimple" id="9b297fb5-d12b-46b1-8899-487a2df0104e" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f"> [prénom] </span> <span type="champsimple" id="e103a6a5-d1be-4c34-8a54-d234179fb4ea" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f">[nom]</span> <span></span> </td> </tr> <tr></tr> <tr> <td></td> <td>Phill It in</td> </tr> <tr> <table id="cas1"> <tr> <td ></td> <td >foo</td> </tr> <tr> <td >bar</td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas2"> <tr> <td ></td> <td >foo</td> </tr> <tr> <td ></td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas3"> <tr> <td >bar</td> <td ></td> </tr> <tr> <td >foo</td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas4"> <tr> <td /> <td /> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <table id="cas4"> <tr> <td /> <td /> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> <tr> <td /> <td /> </tr> </table> Now the question is how would I recursively delete all empty td, tr and table elements? Now I use this XSLT <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*"/> </xsl:copy> </xsl:template> <xsl:template match="td[not(node())]" /> <xsl:template match="tr[not(node())]" /> <xsl:template match="table[not(node())]" /> </xsl:stylesheet> But it doesn't do very well. After I delete td, a tr becomes empty but it doesn't handle that. Too bad. See the table element with "cas4". <table border="1" cols="200 100pt 200"> <tr> <td>isbn</td> <td>title</td> <td>price</td> </tr> <tr> <td> <span type="champsimple" id="9b297fb5-d12b-46b1-8899-487a2df0104e" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f"> [prénom] </span> <span type="champsimple" id="e103a6a5-d1be-4c34-8a54-d234179fb4ea" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f">[nom]</span> <span /> </td> </tr> <tr> <td>Phill It in</td> </tr> <tr> <table id="cas1"> <tr> <td>foo</td> </tr> <tr> <td>bar</td> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas2"> <tr> <td>foo</td> </tr> <tr> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas3"> <tr> <td>bar</td> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas4"> <tr /> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <table id="cas4"> <tr /> <tr> <td>foo</td> <td>boo</td> </tr> </table> <tr /> </table> How would you solve this problem?
