Title: [fixed] possible editor bug
Post by: STxAxTIC on November 06, 2021, 09:37:38 am
its not 2022 yet but i figured yall wanna know what i found whilst running windows 10, all-new qb64-everything as of last week. this problem arose maybe 3x recently, managed to capture it this time:

 
 

when i type (RND - .5) * whatever, the editor removes the .5 and throws the parentheses off.

Confirmed:
(in all the pairs you see before comment removed then after (but comment added back in so I could test more)
Code: QB64: [Select]
  1.  
  2. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) + (Rnd - .5) * BlockSize
  3. 'x = BlockSize * (i - (UBound(WorldMesh, 1) / 2)) + (Rnd () * BlockSize
  4.  
  5. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) +  BlockSize * (Rnd - .5)
  6. 'x = BlockSize * (i - (UBound(WorldMesh, 1) / 2)) + BlockSize * (Rnd ()
  7.  
  8. 'x = BlockSize * (i - UBound(WorldMesh, 1) / 2) +  BlockSize * (Rnd - .5)   'seems like extra set () remove
  9. 'x = BlockSize * (i - UBound(WorldMesh, 1) / 2) + BlockSize * (Rnd ()       ' damn!
  10.  
  11. 'x = BlockSize * (i - UBound(WorldMesh) / 2) + BlockSize * (Rnd -.5)   ' is it 2nd dim of Ubound?
  12. 'x = BlockSize * (i - UBound(WorldMesh) / 2) + BlockSize * (Rnd ()  '  nope still bad!
  13.  
  14. ' x =  i - UBound(WorldMesh) / 2 +  (Rnd -.5)
  15. 'x = i - UBound(WorldMesh) / 2 + (Rnd ()     ' still bad!!!
  16.  
  17. 'x = 10 + 8* (Rnd - .5)
  18. 'x = 10 + 8 * (Rnd - .5)   ' OK
  19.  
  20. 'x = ubound(mesh) + 8* (Rnd - .5)
  21. 'x = UBound(mesh) + 8 * (Rnd ()   ' looks like problem with Ubound
  22.  
  23. 'x = sin(mesh) + 8*(rnd -.5)
  24. 'x = Sin(mesh) + 8 * (Rnd - .5) 'ok
  25.  
  26. Dim Mesh(10 To 20)
  27. 'x = lbound(mesh) + 8* (Rnd - .5)
  28. x = LBound(Mesh) + 8 * (Rnd () ' oops again!  and the M of Mesh is fixed!!!
  29.  
  30.  
  31.  

I suspect when the Case was fixed inside LBound, UBound something got messed up.

Running Windows 10 64 bit QB64 v2.0 going back to older QB64 versions....

Here is QB64 v1.4 all looks good
Code: QB64: [Select]
  1. ' QB64 v1.4
  2. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) + (Rnd - .5) * BlockSize
  3. x = BlockSize * (i - (UBOUND(WorldMesh, 1) / 2)) + (RND - .5) * BlockSize
  4.  
  5.  
  6. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) +  BlockSize * (Rnd - .5)
  7. x = BlockSize * (i - (UBOUND(WorldMesh, 1) / 2)) + BlockSize * (RND - .5)
  8.  
  9.  
  10. 'x = BlockSize * (i - UBound(WorldMesh, 1) / 2) +  BlockSize * (Rnd - .5)   'seems like extra set () remove
  11. x = BlockSize * (i - UBOUND(WorldMesh, 1) / 2) + BlockSize * (RND - .5)
  12.  
  13. 'x = BlockSize * (i - UBound(WorldMesh) / 2) + BlockSize * (Rnd -.5)   ' is it 2nd dim of Ubound?
  14. x = BlockSize * (i - UBOUND(WorldMesh) / 2) + BlockSize * (RND - .5)
  15.  
  16. ' x =  i - UBound(WorldMesh) / 2 +  (Rnd -.5)

  26. x = SIN(mesh) + 8 * (RND - .5)
  27.  
  28. DIM Mesh(10 TO 20)
  29. 'x = lbound(mesh) + 8* (Rnd - .5)
  30. x = LBOUND(mesh) + 8 * (RND - .5)  '<< note mesh still lower case

QB64 v1.5 works OK but ran into problem DIM Mesh after I used Ubound(mesh) a couple times before last pair:
Code: QB64: [Select]
  1. 'QB64 v1.5
  2. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) + (Rnd - .5) * BlockSize
  3. x = BlockSize * (i - (UBound(WorldMesh, 1) / 2)) + (Rnd - .5) * BlockSize
  4.  
  5. 'x = BlockSize * (i - (Ubound(WorldMesh,1)/2)) +  BlockSize * (Rnd - .5)
  6. x = BlockSize * (i - (UBound(WorldMesh, 1) / 2)) + BlockSize * (Rnd - .5)
  7.  
  8. 'x = BlockSize * (i - UBound(WorldMesh, 1) / 2) +  BlockSize * (Rnd - .5)   'seems like extra set () remove
  9. x = BlockSize * (i - UBound(WorldMesh, 1) / 2) + BlockSize * (Rnd - .5)
  10.  
  11. 'x = BlockSize * (i - UBound(WorldMesh) / 2) + BlockSize * (Rnd -.5)   ' is it 2nd dim of Ubound?
  12. x = BlockSize * (i - UBound(WorldMesh) / 2) + BlockSize * (Rnd - .5) '  nope still bad!
  13.  
  14. ' x =  i - UBound(WorldMesh) / 2 +  (Rnd -.5)
  15. x = i - UBound(WorldMesh) / 2 + (Rnd - .5)
  16.  
  17. ' x =  i - UBound(WorldMesh) / 2 +  (Rnd -.5)
  18. x = i - UBound(WorldMesh) / 2 + (Rnd - .5)
  19.  
  20. 'x = ubound(mesh) + 8* (Rnd - .5)
  21. x = UBound(mesh) + 8 * (Rnd - .5)
  22.  
  23. 'x = sin(mesh) + 8*(rnd -.5)
  24. x = Sin(mesh) + 8 * (Rnd - .5)
  25.  
  26. 'Dim mesh(10 To 20)   '' this is red lined in QB64 v1.5 !!!!
  27. ReDim mesh(10 To 20) ' <<<<<<<<<< this refuses to stay with Mesh
  28. 'x = lbound(mesh) + 8* (Rnd - .5)
  29. x = LBound(mesh) + 8 * (Rnd - .5)

Fixed in the latest dev build. We'll be releasing a new stable release. Thanks @STxAxTIC for reporting and @bplus for the help in investigating.
