Python Regex to detect musical chords? (modified) -

-

I am working on a wire transposer in Python, and I'm mostly working, but some problems with my Reggae And I was thinking that if someone is more intelligent in reggax methods then there can be an idea of ​​fixing me. I am essentially using this regex, found in another thread: 

  import ref def (line): notes = "[CDEFGAB]"; Accidental = "(?: ### | B | Bb)?"; Chords = "(?: Maj | min | m | sus | aug | dim)?"; Extra = "[0- 9]?" # A1, which works: Line = "AA7 AM 7 BM CMA 7" Print SearchCode (line) ['A', 'A7', 'M7', 'BB', 'CMJ 7'] # Case 2, who thinks the capital C is a string in the chorus. Line = "chorus: a7 am 7 bb cmaz 7" print searchcard (line) ['c', 'a', 'a7', 'm7', 'bb', 'cmaj 7']   P> As you can see, "Case 1" above works just fine. However, "case 2" fails, the word "chorus" has a wire considering the capital C.  
 Can anyone think of a way to modify the "notes" portion of Regedek, which is smart enough to make such a mistake? This should also leave things like "B" in "baseball" etc.  
 Thanks for any help.   
 
 
 to start regex  r '\ b'  and finally Add  r '(?! \ W!)' , by creating it so that regex can only be against something that is a complete word (where "word" is the sequence of alphanumeric characters and / or underscores Is):  
  def findChords (line): notes = "[CDEFGAB]"; Accidental = "(?: ### | B | Bb)?"; Chords = "(?: Maj | min | m | sus | aug | dim)?"; Extra = "[0- 9]?" Return Refunds (RB + + + Notes + Accidentally + Cord + Adwords + R '(?! \ W)', line)   
 (Note that we can not use  R '\ b'  Finally because a string ending with  #  will never be accepted.)

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...
