tfswitch treats version constraint differently than terraform

[atheri]

If I use the pessimistic constraint like so

terraform {
  required_version = "~> 1.0"
}

terraform will allow me to use terraform version 1.1, but tfswitch will only switch to 1.0.x

╰─ tfswitch
Reading required version from terraform file
Reading required version from constraint: ~> 1.0
Matched version: 1.0.11
Switched terraform to version "1.0.11" 

terraform allowing 1.x version seems consistent with how they documented it here. I would expect tfswitch to follow the same pattern.

[warrensbox]

terraform {
  required_version = "~> 1.0"
}

Should get the latest stable version of 1.0.0 which is 1.0.11

If you want the latest of V1 terraform:
Simply use:

terraform {
  required_version = "~> 1.0"
}

**Should get the latest stable version of 1 ** which is 1.1.4.

I will fix the documentation to reflect this

@warrensbox Last code example should probably have been written as required_version = "~> 1"?

Correct, I had a typo. It should be:

terraform {
  required_version = "~> 1"
}

@warrensbox Just for clarity, I don't think it works quite like the comment.

Testing your fix out locally I get the following results (which is in line with what I expected, but not quite the same as your comment)

terraform {
  required_version = "~> 1.0.0"
}

╰─ ~/go/bin/terraform-switcher
Reading required version from terraform file
Reading required version from constraint: ~> 1.0.0
Matched version: 1.0.11
Switched terraform to version "1.0.11" 

^ Get latest stable of 1.0.x

terraform {
  required_version = "~> 1.0"
}

╰─ ~/go/bin/terraform-switcher
Reading required version from terraform file
Reading required version from constraint: ~> 1.0
Matched version: 1.1.4
Switched terraform to version "1.1.4" 

^ Get latest stable of 1.x.x. This is new, it used to get 1.0.x per the original issue.

terraform {
  required_version = "~> 1"
}

╰─ ~/go/bin/terraform-switcher
Reading required version from terraform file
Reading required version from constraint: ~> 1
Matched version: 1.1.4
Switched terraform to version "1.1.4" 

^ Get latest stable of x.x.x. Coincidentally the same as the last one, but if a 2.0.0 release existed it should return that.
