regex - Unescape unicode in character string -

-

To parse the Jason string with the Unicode escape sequence, it looks like there is a long standing in RJSONIO The bug is like the need to be fixed in the bug libjson which can not be done any time soon, so I have a solution in R which is the first scenes feeding \ uxxxx Some references are being made to create unescapes: Jason data is always unicode, by default using utf-8 , etc. No need to avoid is not. But for historical reasons, JSN supports UNICODE, therefore JSN data 

  {"x": "zürich"}   
 and  
  {"x": "Z \ u00FCrich"}   
 is equivalent and results in exactly the same output when parsed. But for any reason, later does not work in  RJSONIO . The extra is due to the fact that it supports the reserved Unicode itself. So when we type  "Z \ u00FCrich"  in the R console, it automatically gets converted to  "Zürich" . In order to get the actual Jason String in hand, we need to avoid backslash which is the first letter of the Unicode escape sequence in Jason:  
  test & lt; - '{"x": "jade \\ u00FCrich"}' cat (test)   
 So my question is: has given a big Jason string in R, how do I get all the Unicode sequences Can I save To wit. How do I change all the events of  \ uxxxx  by the respective Unicode character? Again, here the  \ uxxxx  represents the actual string of 6 characters, which starts with the backslash. Then a  unescape  function must be completed:  
  #Escaped strings escaped & lt; - "Z \\ u00FCrich" #Unescape Unicode Unescope == "Rich in ZA ¼" This is the only thing unescape (escaped) == "Z \ u00FCrich"   < P> One thing things can be hard to do is that if backslash has escaped json with another backslash, it is  not  part of the Unicode escape sequence like  unescape  should also be completed:  
  escaped the backslash for the unescape #Watch ("Z \\\\ u00FCrich") == "Z \\\\ u00FCrich" unescape ("Z" \\\\ u00FCrich ") ==" Jade \\\\ ¼rich "  
 
 \ Uxxxx  is searching for patterns, and then analyze those parsing those people:  
  unescape_unicode & lt; - Function (X) {#single string only stopifnot (is.character (x) & amp; Length (x) == 1) Metering match #find & lt; - gregexpr ("(\ \\\) + U [0-9A-Z] {4}", X, ignoring SEAS = TRUE) if (ME [[1]] [1]> gt; -1) {#parse matches p & lt; - Vapply (regmatches (x, m) [[1]], function (txt) {gsub ("\\", "\\\\", pars (text = paste 0 ('' ', txt,' '') ) List (p)} x}   
 This works for all cases and I'm not getting any strange results yet

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...
