i'm trying write script update text file replacing instances of characters, (i.e. 'a', 'w') word (i.e. 'airplane', 'worm'). if single line of text this: a.function(); a.callmethod(w); e.aa(w); i'd want become this: airplane.function(); airplane.callmethod(worm); e.aa(worm); the difference subtle important, i'm changing 'a' , 'w' it's used variable, not character in other word. , there's many lines in file. here's i've done far: original = open('original.js', 'r') modified = open('modified.js', 'w') # iterate through each line of file line in original: # search character 'a' when not part of word of sort line = re.sub(r'\w(a)\w', 'airplane', line) modified.write(line) original.close() modified.close() i think re pattern wrong, , think i'm using re.sub() method incorrectly well. appreciated. if you're concerned...

i using qml-box2d library. create box2d body fixtures in c++ , use in qml. unfortunately, time create b2body object , create fixtures object app crashes. if use box2dbody object, comes qml-box2d library, doesn't show in qml. i need box2d body fixtures in c++ collide box2d bodies in qml. proper way this? pay attention - box2dbody not visual item since derived qobject . adds physical properties target . anyway, think easiest way create physical bodies in qml . if still want in c++ can use code below. suppose, have scene in main.qml qml rect item: window { width: 800 height: 600 visible: true world {} rectangle { objectname: "rect" width: 100 height: 100 x: 350 y: 50 color: "green" } rectangle { id: floor height: 50 anchors { left: parent.left right: parent.right bottom: parent.bottom } col...

i have 2 arrays: $users[] , $types[] with return result this: users = array ( [0] => 1 [1] => 1 [2] => 1 ) types = array ( [0] => 0 [1] => 1 [2] => 0 ) how can call them $user['0] , $types['0] in foreach ? want return them this: 1,0 1,1 1,0 foreach ($users $index => $code) { // return users first number echo $code; // want here return type first number of array aswell? } thanks, it's easy: foreach ($users $index => $code) { echo $users[$index].', '.$types[$index]; } if it's possible, each array contains different number of elements (or better don't know, how many items each array contains), should check, if particular element exists in second array: foreach ($users $index => $code) { echo $users[$index].', '.(isset($types[$index]) ? $types[$index] : 'doesn\'t exist'); } you can use example for loop: // array indexes start 0, if they're not set explicitly el...

i came across interview question states: how represent letters a , b , c , d , e , f , g in sorted order using binary tree representation? it's stumped me. if take g root of tree left child e , right child f right subtree "greater than" left subtree. node e, left child , right child b , f 's left child c , right child d . is correct or else have different answer? the binary tree described binary heap , used implement priority queue. instead, use binary search tree , keeps keys in sorted order.

in c#, if implements ix , b inherits , follow b implements ix? if yes because of lsp ? there differences between : 1. interface ix; class : ix; class b : a; and 2. interface ix; class : ix; class b : a, ix; ? is there terminology associated b implementing ix though chain of inheritance or b implementing ix directly? ps: assuming in both cases interface implemented implicitly, not explicitly. patterns utilize on 1 , not work if implemented in 2? from msdn : a class inherits interface implementations provided base classes. without explicitly re-implementing interface, derived class cannot in way alter interface mappings inherits base classes. however, goes on if base class implements interface method virtual, can overridden derived class. implicit implementation can overridden in derived class explicitly.

i'm running shell script gradle, issue shell script running prerequisites need run before gradle continues. i tried following seems gradle opening child process shell script sleep.sh echo 'hi1' sleep 1 echo 'hi2' sleep 10 echo 'bye' gradle: task hello3(type: exec) { println 'start gradle....' commandline 'sh','sleep.sh' println 'end gradle....' } result: start gradle.... end gradle.... :hello3 hi1 hi2 bye your problem println statements executed when gradle parses build.gradle file, not when executes task. you should move println statements dofirst , dolast follows make things clear: task hello3(type: exec) { dofirst { println 'start gradle....' } commandline 'sh','sleep.sh' dolast { println 'end gradle....' } } i believe, gradle waits script finish before doing else, not need special make wait. gradle start shell script in child process. ...

i have got wstring , want convert const char in order write write function of fstream library. tried following: std::ofstream out("test.txt", std::ios::out | std::ios::app | std::ios::binary); char mbstr[11]; std::wcstombs(mbstr, strvalue.c_str(), 11); //strvalue wstring out.write(mbstr, 11); ... // have got 4 wstring. i not sure did, result text file weird: 0.100693 ÌÌ0.000000 ÌÌ0.004094 ÌÌ0.360069 ÌÌ0.086034 any idea how can write wstring in file? you're converting correctly, you're not writing correctly. out << mbstr; . you're writing 11 bytes in array no matter what's in there, , strange characters see random junk after area written wcstombs . of course, better way might use wofstream in first place. can insert wide string directly.
