# Create an enum type for `values`, which additionally accepts deprecated
# values listed in the `renames` attrset as `old = new` pairs.
#
# Example:
#
# vim.languages.typescript.lsp.servers = mkOption {
# type = renamedEnum
# "vim.languages.typescript.lsp.servers"
# ["typescript-language-server" "some-other-server"]
# { ts_ls = "typescript-language-server"; };

#
# With this option definition, when users enter `ts_ls`, they
# get a warning "`ts_ls` is deprecated, use `typescript-language-server`
# instead", and typescript-language-server is automatically used.
