With V 0.1.29 c599a4c on Windows 10 2004:

  1. Works.
  2. Runes aren't implemented, yet.
  3. Works, no warnings.
  4. Works, no warnings.
  5. path_tracing.v needs updated to the latest changes in V. Shows a lot of warnings, now.
  6. Same as 2.
  7. Works, with one warning (due to recent change in V).
  8. This was with v run log.v... and I still get the same output. Is it supposed to crash?
  9. Works, with one warning (due to recent change in V).
  10. Works, with one warning (due to recent change in V).
  11. Works, with one warning (due to recent change in V).
  12. I got a different error.
  13. Works, with one warning (due to recent change in V).
  14. Works.
  15. Works.
  16. Several errors, but this was for older version of V. New net.http code is in a PR.
  17. Definitely needs updated.
  18. I get the same error.
  19. There is no such file in the examples/gg directory now. Probably because the last vestiges of freetype have been removed.
  20. There is no such file in the examples/gg directory now.
  21. Works.

So, with the latest V, there are some warnings to clean up due to recent V changes, a couple of examples need to be updated (they were just plain written for older versions of V), a few things to update, and one duplication for a feature that isn't implemented, yet. Should probably remove that example until it does.

Not as bad as it looked from the list of things above.

  The object of Roulette is to pick the number where the spinning ball will land on the wheel.
   If your number is the good one, you'll get your bet x3.
   If your number is the same color as the ball one, you'll get your bet /2.
   Otherwise, you will lose your bet.

You start the game with 1000 V.

Reminder: odd numbers are red and even are black.
Type the number you want to bet on (between 0 and 49):
2

Is this normall?

Probably, you need a Bourne shell for that. Try MSYS if you're interested.

ntrel picture ntrel on 15 Aug 2020

I'm on Windows 2004 and none of the GUI based examples work at all, while less than half of the command line based ones barely hold themselves together. Problems like this in natively coded examples is likely to cause people(like myself) to view the language or the compiler as buggy and unstable, while disproving your own statements as the language being "stable", and "cross-platform". However, I love the work you guys have put into this and am sure you will fix these someday :D

The problem's only on Windows, all of these will be fixed of course.

Graphical applications should all work now.

As of V 0.1.29 7727aad (commit pushed this morning):

2 - Runes aren't implemented, yet.
5 - path_tracing.v needs updated to the latest changes in V. Shows a lot of warnings, now.
6 - DUPLICATE - Same as 2.
8 - This was with v run log.v... and I still get the same output. Is it supposed to crash?
12 - I got a different error.
16 - Several errors, but this was for older version of V. New net.http code is in a PR.
17 - Definitely needs updated.
18 - I get the same error.

The rest work as expected (or are no longer there). The warnings reported on others are gone.

So out of the 21 issues reported, we're down to only 7 that need some attention. They'll get it once things settle a bit with the compiler and library.
