  • Embed XAML in XML Schema

    - by Michael Stoll
    I'm developping a xml data format. Besides other data there should be a xaml drawing. So I wanted to have a xml element, which can contain any valid xaml. How can this be expressed in the XML Schema? I tried to import the xaml schema, but I couldn't find a xsd file for it. The makeshift would be to use an encoded string.

    Is it possible to set a symbol for conditional compilation by setting up properties in an Xcode project? My aim is to to create a symbol that is available to all files, without having to use import/include, so that a set of common classes can have a special behavior in some projects. Like the following, but with my own symbols. #if TARGET_IPHONE_SIMULATOR ... #endif

  • How to get a html elements with python lxml

    - by Damiano
    Hello! I have this html code: <table> <tr> <td class="test"><b><a href="">aaa</a></b></td> <td class="test">bbb</td> <td class="test">ccc</td> <td class="test"><small>ddd</small></td> </tr> <tr> <td class="test"><b><a href="">eee</a></b></td> <td class="test">fff</td> <td class="test">ggg</td> <td class="test"><small>hhh</small></td> </tr> </table> I use this Python code to extract all <td class="test"> with lxml module. import urllib2 import lxml.html code = urllib.urlopen("http://www.example.com/page.html").read() html = lxml.html.fromstring(code) result = html.xpath('//td[@class="test"][position() = 1 or position() = 4]') It works good! The result is: <td class="test"><b><a href="">aaa</a></b></td> <td class="test"><small>ddd</small></td> <td class="test"><b><a href="">eee</a></b></td> <td class="test"><small>hhh</small></td> (so the first and the fourth column of each <tr>) Now, I have to extract: aaa (the title of the link) ddd (text between <small> tag) eee (the title of the link) hhh (text between <small> tag) How could I extract these values? (the problem is that I have to remove <b> tag and get the title of the anchor on the first column and remove <small> tag on the forth column) Thank you!

  • Reverse PInvoke and create a full unmanaged C# program

    - by Fire-Dragon-DoL
    I know this is a strange question but the idea is simple: I prefer C# syntax rather than C++: -Setters and getters directly inside a property -interfaces -foreach statement -possibility to declare an implicit cast operator other small things... What I really don't know is if is possible to import a c++ dll (expecially std libraries) in C# if I don't use any namespace (even System) The idea is just to write a program using everything that you will normally use in C++ (nothing from CLR so), even printf for example Thanks for any answer

  • What should a Django user know when moving from MySQL to PostgreSQL?

    - by tmitchell
    Most of my experience with Django thus far has been with MySQL and mysqldb. For a new app I'm writing, I'm dipping my toe in the PostgreSQL water, now that I have seen the light. While writing a data import script, I stumbled upon an issue with the default autocommit behavior. I would guess there are other "gotchas" that might crop up. What else should I be on the lookout for?

  • Can parser combination be made efficient?

    - by Jon Harrop
    Around 6 years ago, I benchmarked my own parser combinators in OCaml and found that they were ~5× slower than the parser generators on offer at the time. I recently revisited this subject and benchmarked Haskell's Parsec vs a simple hand-rolled precedence climbing parser written in F# and was surprised to find the F# to be 25× faster than the Haskell. Here's the Haskell code I used to read a large mathematical expression from file, parse and evaluate it: import Control.Applicative import Text.Parsec hiding ((<|>)) expr = chainl1 term ((+) <$ char '+' <|> (-) <$ char '-') term = chainl1 fact ((*) <$ char '*' <|> div <$ char '/') fact = read <$> many1 digit <|> char '(' *> expr <* char ')' eval :: String -> Int eval = either (error . show) id . parse expr "" . filter (/= ' ') main :: IO () main = do file <- readFile "expr" putStr $ show $ eval file putStr "\n" and here's my self-contained precedence climbing parser in F#: let rec (|Expr|) (P(f, xs)) = Expr(loop (' ', f, xs)) and shift oop f op (P(g, xs)) = let h, xs = loop (op, g, xs) loop (oop, f h, xs) and loop = function | ' ' as oop, f, ('+' | '-' as op)::P(g, xs) | (' ' | '+' | '-' as oop), f, ('*' | '/' as op)::P(g, xs) | oop, f, ('^' as op)::P(g, xs) -> let h, xs = loop (op, g, xs) let op = match op with | '+' -> (+) | '-' -> (-) | '*' -> (*) | '/' -> (/) | '^' -> pown loop (oop, op f h, xs) | _, f, xs -> f, xs and (|P|) = function | '-'::P(f, xs) -> let f, xs = loop ('~', f, xs) P(-f, xs) | '('::Expr(f, ')'::xs) -> P(f, xs) | c::xs when '0' <= c && c <= '9' -> P(int(string c), xs) My impression is that even state-of-the-art parser combinators waste a lot of time back tracking. Is that correct? If so, is it possible to write parser combinators that generate state machines to obtain competitive performance or is it necessary to use code generation?

  • Python multiprocessing global variable updates not returned to parent

    - by user1459256
    I am trying to return values from subprocesses but these values are unfortunately unpicklable. So I used global variables in threads module with success but have not been able to retrieve updates done in subprocesses when using multiprocessing module. I hope I'm missing something. The results printed at the end are always the same as initial values given the vars dataDV03 and dataDV04. The subprocesses are updating these global variables but these global variables remain unchanged in the parent. import multiprocessing # NOT ABLE to get python to return values in passed variables. ants = ['DV03', 'DV04'] dataDV03 = ['', ''] dataDV04 = {'driver': '', 'status': ''} def getDV03CclDrivers(lib): # call global variable global dataDV03 dataDV03[1] = 1 dataDV03[0] = 0 # eval( 'CCL.' + lib + '.' + lib + '( "DV03" )' ) these are unpicklable instantiations def getDV04CclDrivers(lib, dataDV04): # pass global variable dataDV04['driver'] = 0 # eval( 'CCL.' + lib + '.' + lib + '( "DV04" )' ) if __name__ == "__main__": jobs = [] if 'DV03' in ants: j = multiprocessing.Process(target=getDV03CclDrivers, args=('LORR',)) jobs.append(j) if 'DV04' in ants: j = multiprocessing.Process(target=getDV04CclDrivers, args=('LORR', dataDV04)) jobs.append(j) for j in jobs: j.start() for j in jobs: j.join() print 'Results:\n' print 'DV03', dataDV03 print 'DV04', dataDV04 I cannot post to my question so will try to edit the original.

  • Grails validateable not work for non-persistent domain class

    - by Hoàng Long
    I followed the instruction here: http://www.grails.org/doc/latest/guide/7.%20Validation.html and added into config.groovy: grails.validateable.classes = [liningtest.Warm'] Then added in src/groovy/Warm.groovy (it's a non-persistent domain class): package liningtest import org.codehaus.groovy.grails.validation.Validateable class Warm { String name; int happyCite; Warm(String n, int h) { this.name = n; this.happyCite = h; } static constraints = { name(size: 1..50) happyCite(min: 100) } } But it just doesn't work (both "blank false" & "size: 0..25") for the "hasErrors" function. It always returns false, even when the name is 25. Is this a Grails bug, if yes, is there any work-around? I'm using Grails 1.3.3 UPDATE: I have updated the simplified code. And now I know that constraint "size" can't be used with "blank", but still does not work. My test class in test/unit/liningtest/WarmTests.groovy package liningtest import grails.test.* class WarmTests extends GrailsUnitTestCase { protected void setUp() { super.setUp() } protected void tearDown() { super.tearDown() } void testSomething() { def w = new Warm('Hihi', 3) assert (w.happyCite == 3) assert (w.hasErrors() == true) } } And the error I got: <?xml version="1.0" encoding="UTF-8" ?> <testsuite errors="1" failures="0" hostname="evolus-50b0002c" name="liningtest.WarmTests" tests="1" time="0.062" timestamp="2010-12-16T04:07:47"> <properties /> <testcase classname="liningtest.WarmTests" name="testSomething" time="0.062"> <error message="No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode()" type="groovy.lang.MissingMethodException">groovy.lang.MissingMethodException: No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode() at liningtest.WarmTests.testSomething(WarmTests.groovy:18) </error> </testcase> <system-out><![CDATA[--Output from testSomething-- ]]></system-out> <system-err><![CDATA[--Output from testSomething-- ]]></system-err> </testsuite> UPDATE 2: When I don't use Unit test, but try to call hasErrors in the controller, it runs but return false value. (hasErrors return false with Warm('Hihi', 3) ). Does anyone has a clue?

  • Avoiding stack overflows in wrapper DLLs

    - by peachykeen
    I have a program to which I'm adding fullscreen post-processing effects. I do not have the source for the program (it's proprietary, although a developer did send me a copy of the debug symbols, .map format). I have the code for the effects written and working, no problems. My issue now is linking the two. I've tried two methods so far: Use Detours to modify the original program's import table. This works great and is guaranteed to be stable, but the user's I've talked to aren't comfortable with it, it requires installation (beyond extracting an archive), and there's some question if patching the program with Detours is valid under the terms of the EULA. So, that option is out. The other option is the traditional DLL-replacement. I've wrapped OpenGL (opengl32.dll), and I need the program to load my DLL instead of the system copy (just drop it in the program folder with the right name, that's easy). I then need my DLL to load the Cg framework and runtime (which relies on OpenGL) and a few other things. When Cg loads, it calls some of my functions, which call Cg functions, and I tend to get stack overflows and infinite loops. I need to be able to either include the Cg DLLs in a subdirectory and still use their functions (not sure if it's possible to have my DLLs import table point to a DLL in a subdirectory) or I need to dynamically link them (which I'd rather not do, just to simplify the build process), something to force them to refer to the system's file (not my custom replacement). The entire chain is: Program loads DLL A (named opengl32.dll). DLL A loads Cg.dll and dynamically links (GetProcAddress) to sysdir/opengl32.dll. I now need Cg.dll to also refer to sysdir/opengl32.dll, not DLL A. How would this be done? Edit: How would this be done easily without using GetProcAddress? If nothing else works, I'm willing to fall back to that, but I'd rather not if at all possible. Edit2: I just stumbled across the function SetDllDirectory in the MSDN docs (on a totally unrelated search). At first glance, that looks like what I need. Is that right, or am I misjudging? (off to test it now) Edit3: I've solved this problem by doing thing a bit differently. Instead of dropping an OpenGL32.dll, I've renamed my DLL to DInput.dll. Not only does it have the advantage of having to export one function instead of well over 120 (for the program, Cg, and GLEW), I don't have to worry about functions running back in (I can link to OpenGL as usual). To get into the calls I need to intercept, I'm using Detours. All in all, it works much better. This question, though, is still an interesting problem (and hopefully will be useful for anyone else trying to do crazy things in the future). Both the answers are good, so I'm not sure yet which to pick...
