7974 :: Nimble Disallow Version

• fengkehh (orginal) [2021-05-13T20:34:22+02:00] view original

  I built a library using Weave which is currently incompatible with nim 1.4.6 currently. As such I have specified in its nimble file:

  
  requires nim >= 1.4
  requires nim < 1.4.6
  Run

  Turns out problem with Weave was fixed in the current 1.5.1 devel past 04/30/2021. So right now I'd like to specifically blacklist Nim 1.4.6 but allow anything else past 1.4. Is there a way to do this in the nimble file? I've tried requires nim != 1.4.6 already and it doesn't seem to work.

  What is the commit in devel that fixes it? We might want to backport it to 1.4.8 and hen you can simply say requires nim >= 1.4.8.

  I'm guessing this: https://github.com/nim-lang/Nim/pull/13793

  I could be wrong though. Here's the issue post on Weave repo: https://github.com/mratsim/weave/issues/171

  It could be this one https://github.com/nim-lang/Nim/commit/444658fe5817808d71c06f1b5c272c1132d89bfb

  How it's done in other PM:s: https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#multiple-requirements

  Unfortunately nimble's version string parser is a bit barebones right now. AFAIK it can't really parse single line ranged versions involving logical AND through ,. This is why I'm working around it using two lines of requires nim. Also doesn't seem to understand != unlike pip.

  Here is how you would do it in Nimble:

  
  requires "nim >= 1.4 & < 1.4.6"
  Run

  Should work, we've got tests for this: https://github.com/nim-lang/nimble/blob/master/src/nimblepkg/version.nim#L300 :)

  Works like a charm, thanks! Is there a way to do logical OR or NOT?

---

• dom96 (orginal) [2021-05-16T01:25:21+02:00] view original

  Nope, but I don't think those are necessary. Can you give an example where you'd use them?

  Mainly to blacklist a particular version of a library etc. For example, even if 1.4.8 has the compatibility fixes for Weave backported to it, as it is right now it will require me to effectively blacklist all Nim versions prior to 1.4.8. With negation or OR I can blacklist just 1.4.6.
