rlang minimum version

[igordot]

You should add a minimum version for rlang in DESCRIPTION. I got an error installing styler 1.1.0. It was resolved by updating rlang to the latest version (0.3). I forgot to record the exact error I got, but it was environment-related. For example, you use rlang::new_environment() which was added in 0.1.1, so it would have to be at least that recent.

Thanks. Indeed you are right:

# remotes::install_github("lorenzwalthert/namespaces")
namespaces::find_first_release("rlang", "new_environment")
#> [1] "0.1.1"

Oh wow! I didn't know about namespaces::find_first_release(). It seems like something that should be in usethis or testthat.

It was a toy project so far, but it indeed might prove useful. However, it still can only handle standard exports, has no unit tests etc. Maybe it could be imported by another package if it is more mature. Also, it needs to do binary search on the NAMESPACE file of all releases for a package via
the GitHub API for https://github.com/cran, which is not very elegant, but I am not sure what else to do.
