This is problematic, as the lib value is a unique key passed via -m. This will effectively mean that the CommonMarker (pre 1.0?) class could never be activated. We should definitely maintain support for the old format, which would require this commonmarker key be changed-- it's not idela, but maybe :commonmarker1?

CommonMarker seems still accessible.

Even if it’s not, v1.0 CommonMaker should have priority over pre-1.0 Commonmarker.
Separating a commonmarker1 key keeps commonmarker out of date.
YARD does not have a system that checks provider versions and has long1 exposed users to Commonmarker 1.0’s backward incompatibility. We should improve this compatibility rather than make users work an extra step.

Even if it’s not, v1.0 CommonMaker should have priority over pre-1.0 Commonmarker.

Unfortunately this would be a breaking change and would need a major version bump-- we're very unlikely to major version bump YARD just for a single (optional) markup library.

YARD is currently still in 0.x versions, so I’m not sure what you meant by ‘major’.

That said, together with #1540 (comment), I see your concern.
YARD currently has designs tailored for CommonMarker v0.x but it’s not documented anywhere.
We can only treat Commonmarker v1.x as a separate provider.

YARD's 0.x releases are a major version. Believe it or not, there was a time before "SemVer", and YARD predates the existence of the now-popular semantic versioning specification, along with its arbitrary distinction that only 1.0+ are considered API stable. YARD's 0.x releases are considered a stable API. "0" is the current major version for YARD, we simply use 0-based indexing.

YARD does not have a system that checks provider versions

We might wanna add one. But for now, …

YARD currently has designs tailored for CommonMarker v0.x but it’s not documented anywhere.

… I’ll add a comment in the code since it’s now linked in the README.

At first glance it seems like YARD is no longer able to support the pre 1.0 commonmarker lib due to a change in the markup_helper lookup table.

Actually, we might not be able to support both Commonmarker and CommomMarker at all.
Commonmarker 1.x shadows CommonMarker 0.x. We’d have to write individual Bundler.requires in our specs.

This should stay as skip for systems that do not have the dependencies installed (testing outside of bundle exec).
