Newer versions of mise specifically only
look for tool versions in mise.toml as well as the asdf .tool-versions file.
A lot of Ruby projects use the .ruby-version file to indicate the Ruby version
of a project. To continue to use the .ruby-version file instead of migrating
to mise.toml, you need to tell mise that you prefer to use the idiomatic
version file.
I added the following line to my
~/.config/mise/config.toml
file:
idiomatic_version_file_enable_tools = ["ruby"]Now, whenever mise is looking for the specified Ruby version of a project, it
will also look for .ruby-version.
Here is a full list of idomatic version files supported by
mise.
See
idiomatic_version_file_enable_tools
as well as the Ruby-specific documentation
for more details.
