def TLA.ProofMode.tlaClearExceptTac : Lean.ParserDescr

tla_clear * - h₁ h₂ ... removes every temporal hypothesis except the named ones. The kept hypotheses stay in their original order. For example, from hp : p, hq : q, hr : r,

tla_clear * - hq

leaves only hq : q.

def TLA.ProofMode.tlaClearTac : Lean.ParserDescr

tla_clear h₁ h₂ ... removes temporal hypotheses from the proof-mode context. The target predicate is unchanged, but the remaining proof must not use the cleared hypotheses.

For example, from a context containing hp : p, hq : q, and goal q,

tla_clear hp

leaves only hq : q in the proof-mode context.
