php - How can ignore a string in quotes in this regex match? -

-

How can I ignore the examples of string "or" when inside single / double quotes?

The current expression is / ^ (? = \ $) (. +?) (?: \ S + or \ s +) (. +?) $ / S < / P>

Test value 1: $ test or "default value"

Test value 2: $ errors- & gt; Is ('email')? 'Error or failure': ''

Test value should affect 1, but value 2 should be unaffected.

Test Script:

To update $ expression . 

  & lt ;? Php function issetDefaults ($ value) {// Original expression with problem // $ expression = '/ ^ (? = \ $) (. +)) ??? s = ++++++ (++) ) / S '; // @ Avinash Raj's version; Almost there; Test 2 $ has failed on expression = '/ ([\' 'altered] (??? :: ?? \\).) * Or (? :(?!? 1).) ****** **************************************************************************************************** ***). ^ (\ S +) or ([\ '"]. * [\'"]) / '; Return preg_replace ($ expression, 'provider ($ 2)' $ 2: $ 3 ', $ value);} // test $ Tests = array (//' $ test or 'default value' ',' $ age or 90 'Myfunc' (\ 'foo or bar \') should not be affected, '$ errors (' 'email' ')? \' Error or failure \ ': \' \ ',' $ errors- & ("Email")? "Error or failure": "" ',' $ Errors- & gt; ("email") "error" or "failure": "" '); // Output Test Foreign Currency ($ test as $ rate => $ test) {$ num = $ key 1; Anco '& lt; Strong & gt; Original value '. $ Num '& Lt; / Strong> Echo '& lt; Pre & gt; Print (Test $ true,). & Lt; / Pre & gt; '; Echo '& lt; Strong & gt; Values ​​'. $ Num. ' '& Lt; / Pre & gt; '; Echo '& lt; Hr / & gt; ';}  after work & lt; / Strong> 'Echo' & lt; Pre & gt; 'Print_r (issetDefaults ($ test)   
 
 
 Regex string  or  Which would not match within the single or double quotes,  
  ([?]) (?: (? !! 1).) Or (?: (?! \ 1 ). * 1 (* SKIP)

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
