  • Debian package libmarkdown-php, how can I use it? [closed]

    - by JamesM-SiteGen
    Hello all, I am just wondering how do you implement libmarkdown-php in a php script? By this, I mean: What code do I run to use the markdown library? Does it simply just add one function? Does it allows me to encode markdown2html and vise versa? Where is a doc for this package, I can't find one? :( Okay, so it terns out that I found the docs, just did not match them up, the project-page did not contain any info on it being the Squeeze package libmarkdown-php, Said to know it is not in Lenny. Thanks @palhmbus for matching them. :)

  • Rendering citations and references in HTML using PHP/Perl/Python/

    - by Nick
    Is there a PHP/Perl/Python/... library for picking citations out of an HTML file and rendering a nice list of references at the bottom, like in Wikipedia? I'm developing a website with heavily-sourced content, and I'd really like to have automatically-generated lists of formatted references, like in Wikipedia. (Check out their philosophy page, and see how the superscript numbered citations interact with the references at the bottom. This is all dynamically generated, automatically ordered & linked.) They do it really well: the citations are linked to the references (which are backlinked to the citations), when you click on one of the links, the target is highlighted, etc. I'm tempted to build the site on MediaWiki just for this one feature, but it seems like overkill. Do I have any options?

  • Is there a portal dedicated to HTML5 games?

    - by Bane
    Just to get something straight; by "portal", I mean a website that frequently publishes a certain type of games, has a blog, some articles, maybe some tutorials and so on. All of these things are not required (except the game publishing part, of course), for example, I consider Miniclip to be a flash game portal. The reason for defining this term is because I'm not sure if other people use it in this context. I recently (less than a year ago) got into HTML5 game development, nothing serious, just my own small projects that I didn't really show to a lot of people, and that certainly didn't end up somewhere on the web (although, I am planning to make a website for my next game). I am interested in the existence of an online portal where indie devs (or non-indie ones, doesn't really matter that much) can publish their own games, sort of like "by devs for devs", also a place where you can find some simple tutorials on basic HTML5 game development and so on... I doubt something like this exists for several reasons: You can't really commercialize an HTML5 game without a strong server-side and microtransactions The code can be easily copied HTML5 is simply new, and things need time to get their own portals somewhere... If a thing like this does not exist, I think I might get into making one some day...

  • Python Image Library: How to combine 4 images into a 2 x 2 grid?

    - by Casey
    I have 4 directories with images for an animation. I would like to take the set of images and generate a single image with the 4 images arranged into a 2x2 grid for each frame of the animation. My code so far is: import Image fluid64 = "Fluid64_half_size/00" fluid128 = "Fluid128_half_size/00" fluid512 = "Fluid512_half_size/00" fluid1024 = "Fluid1024_half_size/00" out_image = "Fluid_all/00" for pic in range(1, 26): blank_image = Image.open("blank.jpg") if pic < 10: image_num = "0"+str(pic) else: image_num = str(pic) image64 = Image.open(fluid64+image_num+".jpg") image128 = Image.open(fluid128+image_num+".jpg") image512 = Image.open(fluid512+image_num+".jpg") image1024 = Image.open(fluid1024+image_num+".jpg") out = out_image + image_num + ".jpg" blank_image.paste(image64, (0,0)).paste(fluid128, (400,0)).paste(fluid512, (0,300)).paste(fluid1024, (400,300)).save(out) Not sure why it's not working. I'm getting the error: Traceback (most recent call last): File "C:\Users\Casey\Desktop\Image_composite.py", line 24, in <module> blank_image.paste(image64, (0,0)).paste(fluid128, (400,0)).paste(fluid512, ( ste(fluid1024, (400,300)).save(out) AttributeError: 'NoneType' object has no attribute 'paste' shell returned 1 Any help would be awesome.

  • Does anyone know of a library in Java that can parse ESRI Shapefiles?

    - by KingNestor
    I'm interested in writing a visualization program for the road data in the 2009 Tiger/Line Shapefiles. I'd like to draw the line data to display all the roads for my county. The ESRI Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products.1 A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required. Does anyone know of existing libraries for parsing and reading in the line data for Shapefiles?

  • Compiling external C++ library (Octave) for iPhone (Fortran compiler missing?)

    - by Shaggy Frog
    A friend of mine asked me if it would be possible to port the Octave project to the iPhone. I haven't compiled an external package for an iPhone project before, so I downloaded the source code, and then used some scripts found on a couple of different Web sites (one, two) to try and build the libraries. However, when I try either of these scripts (which are nearly identical), they eventually die during the configure phase with the following error output: [...snip checks...] checking whether we are using the GNU Fortran 77 compiler... no checking whether accepts -g... no checking how to get verbose linking output from ... configure: WARNING: compilation failed checking for Fortran 77 libraries of ... rm: conftest.dSYM: is a directory checking for dummy main to link with Fortran 77 libraries... rm: conftest.dSYM: is a directory none checking for Fortran 77 name-mangling scheme... configure: error: cannot compile a simple Fortran program See `config.log' for more details. Is the problem that the iPhone SDK/Xcode doesn't include a Fortran cross-compiler, or am I doing something wrong?

  • Haskell Linear Algebra Matrix Library for Arbitrary Element Types

    - by Johannes Weiß
    I'm looking for a Haskell linear algebra library that has the following features: Matrix multiplication Matrix addition Matrix transposition Rank calculation Matrix inversion is a plus and has the following properties: arbitrary element (scalar) types (in particular element types that are not Storable instances). My elements are an instance of Num, additionally the multiplicative inverse can be calculated. The elements mathematically form a finite field (??2256). That should be enough to implement the features mentioned above. arbitrary matrix sizes (I'll probably need something like 100x100, but the matrix sizes will depend on the user's input so it should not be limited by anything else but the memory or the computational power available) as fast as possible, but I'm aware that a library for arbitrary elements will probably not perform like a C/Fortran library that does the work (interfaced via FFI) because of the indirection of arbitrary (non Int, Double or similar) types. At least one pointer gets dereferenced when an element is touched (written in Haskell, this is not a real requirement for me, but since my elements are no Storable instances the library has to be written in Haskell) I already tried very hard and evaluated everything that looked promising (most of the libraries on Hackage directly state that they wont work for me). In particular I wrote test code using: hmatrix, assumes Storable elements Vec, but the documentation states: Low Dimension : Although the dimensionality is limited only by what GHC will handle, the library is meant for 2,3 and 4 dimensions. For general linear algebra, check out the excellent hmatrix library and blas bindings I looked into the code and the documentation of many more libraries but nothing seems to suit my needs :-(. Update Since there seems to be nothing, I started a project on GitHub which aims to develop such a library. The current state is very minimalistic, not optimized for speed at all and only the most basic functions have tests and therefore should work. But should you be interested in using or helping out developing it: Contact me (you'll find my mail address on my web site) or send pull requests.

  • Java: Use jar library's from package manager in Linux.

    - by jonescb
    I'm trying to find the best way to use Java libraries that were installed by the package manager instead of just putting a copy into ${project.root}/lib My distro, Gentoo, has a package for Java libraries like jdbc-postgresql. It's installed to /usr/share/jdbc-postgresql/lib/jdbc-postgresql.jar I assume that this path may be different in Ubuntu, Fedora, or Arch. Is there any way to do like what C does? Where you just add a -lfoo, and the linker would find libfoo.so. I'm using Ant 1.8.0 and Java 1.6.0_19.

  • Getting 'error while loading shared libraries' when using -L to specifically find the library.

    - by e5
    I've been trying to solve this for a few hours now. I am compiling some c files using gcc. The files require libpbc, so I am using the -L flag to point gcc at the directory which contains libpbc.so.1. The code compiles without error yet when I attempt to run it I get the following error message: ./example.out: error while loading shared libraries: libpbc.so.1: cannot open shared object file: No such file or directory Looking at similar questions this error message seems to indicate that gcc can't find libpbc.so.1. I know gcc sees libpbc.so.1 because when I rename libpbc.so.1 to something else it fails to compile. I am using -L to point to the directory which contains libpbc.so.1. Not sure what next steps I can take to figure this out. Would appreciate any ideas. What does this error message mean exactly?

  • Is this too much code for a header only library?

    - by Billy ONeal
    It seems like I had to inline quite a bit of code here. I'm wondering if it's bad design practice to leave this entirely in a header file like this: #pragma once #include <string> #include <boost/noncopyable.hpp> #include <boost/make_shared.hpp> #include <boost/iterator/iterator_facade.hpp> #include <Windows.h> #include "../Exception.hpp" namespace WindowsAPI { namespace FileSystem { class FileData; struct AllResults; struct FilesOnly; template <typename Filter_T = AllResults> class DirectoryIterator; namespace detail { class DirectoryIteratorImpl : public boost::noncopyable { WIN32_FIND_DATAW currentData; HANDLE hFind; std::wstring root; public: inline DirectoryIteratorImpl(); inline explicit DirectoryIteratorImpl(const std::wstring& pathSpec); inline void increment(); inline bool equal(const DirectoryIteratorImpl& other) const; inline const std::wstring& GetPathRoot() const; inline const WIN32_FIND_DATAW& GetCurrentFindData() const; inline ~DirectoryIteratorImpl(); }; } class FileData //Serves as a proxy to the WIN32_FIND_DATA struture inside the iterator. { boost::shared_ptr<detail::DirectoryIteratorImpl> iteratorSource; public: FileData(const boost::shared_ptr<detail::DirectoryIteratorImpl>& parent) : iteratorSource(parent) {}; DWORD GetAttributes() const { return iteratorSource->GetCurrentFindData().dwFileAttributes; }; bool IsDirectory() const { return (GetAttributes() | FILE_ATTRIBUTE_DIRECTORY) != 0; }; bool IsFile() const { return !IsDirectory(); }; bool IsArchive() const { return (GetAttributes() | FILE_ATTRIBUTE_ARCHIVE) != 0; }; bool IsReadOnly() const { return (GetAttributes() | FILE_ATTRIBUTE_READONLY) != 0; }; unsigned __int64 GetSize() const { ULARGE_INTEGER intValue; intValue.LowPart = iteratorSource->GetCurrentFindData().nFileSizeLow; intValue.HighPart = iteratorSource->GetCurrentFindData().nFileSizeHigh; return intValue.QuadPart; }; std::wstring GetFolderPath() const { return iteratorSource->GetPathRoot(); }; std::wstring GetFileName() const { return iteratorSource->GetCurrentFindData().cFileName; }; std::wstring GetFullFileName() const { return GetFolderPath() + GetFileName(); }; std::wstring GetShortFileName() const { return iteratorSource->GetCurrentFindData().cAlternateFileName; }; FILETIME GetCreationTime() const { return iteratorSource->GetCurrentFindData().ftCreationTime; }; FILETIME GetLastAccessTime() const { return iteratorSource->GetCurrentFindData().ftLastAccessTime; }; FILETIME GetLastWriteTime() const { return iteratorSource->GetCurrentFindData().ftLastWriteTime; }; }; struct AllResults : public std::unary_function<const FileData&, bool> { bool operator()(const FileData&) { return true; }; }; struct FilesOnly : public std::unary_function<const FileData&, bool> { bool operator()(const FileData& arg) { return arg.IsFile(); }; }; template <typename Filter_T> class DirectoryIterator : public boost::iterator_facade<DirectoryIterator<Filter_T>, const FileData, std::input_iterator_tag> { friend class boost::iterator_core_access; boost::shared_ptr<detail::DirectoryIteratorImpl> impl; FileData current; Filter_T filter; void increment() { do { impl->increment(); } while (! filter(current)); }; bool equal(const DirectoryIterator& other) const { return impl->equal(*other.impl); }; const FileData& dereference() const { return current; }; public: DirectoryIterator(Filter_T functor = Filter_T()) : impl(boost::make_shared<detail::DirectoryIteratorImpl>()), current(impl), filter(functor) { }; explicit DirectoryIterator(const std::wstring& pathSpec, Filter_T functor = Filter_T()) : impl(boost::make_shared<detail::DirectoryIteratorImpl>(pathSpec)), current(impl), filter(functor) { }; }; namespace detail { DirectoryIteratorImpl::DirectoryIteratorImpl() : hFind(INVALID_HANDLE_VALUE) { } DirectoryIteratorImpl::DirectoryIteratorImpl(const std::wstring& pathSpec) { std::wstring::const_iterator lastSlash = std::find(pathSpec.rbegin(), pathSpec.rend(), L'\\').base(); root.assign(pathSpec.begin(), lastSlash); hFind = FindFirstFileW(pathSpec.c_str(), &currentData); if (hFind == INVALID_HANDLE_VALUE) WindowsApiException::ThrowFromLastError(); while (!wcscmp(currentData.cFileName, L".") || !wcscmp(currentData.cFileName, L"..")) { increment(); } } void DirectoryIteratorImpl::increment() { BOOL success = FindNextFile(hFind, &currentData); if (success) return; DWORD error = GetLastError(); if (error == ERROR_NO_MORE_FILES) { FindClose(hFind); hFind = INVALID_HANDLE_VALUE; } else { WindowsApiException::Throw(error); } } DirectoryIteratorImpl::~DirectoryIteratorImpl() { if (hFind != INVALID_HANDLE_VALUE) FindClose(hFind); } bool DirectoryIteratorImpl::equal(const DirectoryIteratorImpl& other) const { if (this == &other) return true; return hFind == other.hFind; } const std::wstring& DirectoryIteratorImpl::GetPathRoot() const { return root; } const WIN32_FIND_DATAW& DirectoryIteratorImpl::GetCurrentFindData() const { return currentData; } } }}

  • Static library woes in iPhone 3.x with categories and C libraries

    - by hgpc
    I have a static library (let's call it S) that uses a category (NSData+Base64 from MGTwitterEngine) and a C library (MiniZip wrapped by ZipArchive). This static library is used in an iPhone 3.x project (let's call it A). To be able to use the MiniZip library I included its files in project A as well as the static library S. If not I get compilation errors. Project A works fine on the simulator. When I run it on the device, I get unrecognized selector errors when the category is used. As pointed out here, it seems there's a linker bug that affects categories in iPhone 3.x (http://stackoverflow.com/questions/1147676/categories-in-static-library-for-iphone-device-3-0). The workaround is to add -all_load to the Other Linker Flags of the project that references the static library. However, if I do this then I get duplicate symbol errors because I included the MiniZip libraries in project A. A workaround is to include the category files in project A as well. If I do this, project A works well in the device, but fails to build on the simulator because of duplicate symbol errors. How should I set up project A to make it work on the simulator and the device with the same configuration?

  • filtering itunes library items by file location

    - by Cawas
    3 answers and unfortunately no solution yet. The Problem I've got way more than 1000 duplicated items in my iTunes Library pointing to a non-existant place (the "where" under "get info" window), along with other duplicated items and other MIAs (Missing In Action). Is there any simple way to just delete all of them and only them? From the library, of course. By that I mean some MIAs are pointing to /Volumes while some are pointing to .../music/Music/... or just .../music/.... I want to delete all pointing to /Volumes as to later I'll recover the rest. Check the image below. Some Background I tried searching for a specific key word on the path and creating smart play list, but with no result. Being able to just sort all library by path would be a perfect solution! I believe old iTunes could do that. PowerTunes can do it (sort by path) but I can't do anything with its list. I would also welcome any program able to handle this, then import and properly export back the iTunes library. Since this seems to just not be clear enough... AppleScript doesn't work That's because AppleScript just can't gather the missing info anywhere in iTunes Library. Maybe we could use AppleScript by opening the XML file, but that's a whole nother issue. Here's a quote from my conversation with Doug the man himself Adams last december: I don't think you do understand. There is no way to get the path to the file of a dead track because iTunes has "forgotten" it. That is, by definition, what a dead track is. Doug On Dec 21, 2010, at 7:08 AM, Caue Rego wrote: yes I understand that and have seem the script. but I'm not looking for the file. just the old broken path reference to it. Sent from my iPhone On 21/12/2010, at 10:00, Doug Adams wrote: You cannot locate missing files of dead tracks because, by definition, a dead track is one that doesn't have any file information. If you look at "Super Remove Dead Tracks", you will notice it looks for tracks that have "missing value" for the location property.

  • LGPL library with plugins of varied licenses

    - by Chris
    Note: "Plugins" here refers to shared objects that are accessed via dlopen() and friends. I'm writing a library that I'm planning on releasing under the LGPL. Its functionality can be extended (supporting new audio file formats, specifically) through plugins. I'm planning on creating an exception to the LGPL for this library so that plugins can be released under any license. So far so good. I've written a number of plugins already, some of which use LGPL and some of which use GPL libraries. I'm wary of releasing them with the main library, however, due to licensing issues. The LGPL-based ones would generally be fine, but for my "any license" clause. Would distributing these LGPL-based plugins with the library require the consent of the other license holders to create this exception? Along the same lines, would the inclusion of GPL-based plugins with my library force the whole thing to go GPL? I could also release the plugins separately. The advantage, I presume, is that the plugins an d library will now not be distributed together, creating more separation. But this seems to be no different, really, in the end. Boiled down: Can I include, with my LGPL library, plugins of varied licenses? If not, is it really any different releasing them separately? And if so, there's no real need to create an exception for non-LGPL plugins, is there? It's LGPL or nothing. I'd prefer asking a lawyer, of course, but this is just a hobby and I can't afford to hire a lawyer when I don't expect or want monetary compensation. I'm just hoping others have been in similar situations and have insight.

  • How does Task Parallel Library scale on a terminal server or in a web application?

    - by Lasse V. Karlsen
    I understand that the TPL uses work-stealing queues for its tasks when I execute things like Parallel.For and similar constructs. If I understand this correctly, the construct will spin up a number of tasks, where each will start processing items. If one of the tasks complete their allotted items, it will start stealing items from the other tasks which hasn't yet completed theirs. This solves the problem where items 1-100 are cheap to process and items 101-200 are costly, and one of the two tasks would just sit idle until the other completed. (I know this is a simplified exaplanation.) However, how will this scale on a terminal server or in a web application (assuming we use TPL in code that would run in the web app)? Can we risk saturating the CPUs with tasks just because there are N instances of our application running side by side? Is there any information on this topic that I should read? I've yet to find anything in particular, but that doesn't mean there is none.

  • How are Flash library symbols constructed? Why are width/height already available in constructor?

    - by Triynko
    Suppose I draw a square on the stage, convert it to a symbol, export it for ActionScript with a classname of "MySquare" (and of course a base class of MovieClip). How is it that in the MySquare constructor, the width and height of this MovieClip are already available? In fact, any named instances in the clip are also available. I'm confused about how the Flash player seems to be able to pre-construct my movie clip by populating its properties and child clips before my constructor for the class ever runs. I thought that it would have to first construct the clip, calling my constructor code, and then construct and add any children, but obviously the player is doing something special for clips designed in the Flash authoring environment.
