Fix formatting line splits in OrdinaryDiffEq.jl

claude · claude · commit aef4ff92b051 · 2025-08-01T11:36:27.000-04:00
Fixed 12 instances of unnecessary line splits across multiple algorithm implementations: - benchmark/benchmarks.jl: Fixed 3 mathematical expressions in reaction and Brusselator systems - test/modelingtoolkit/preconditioners.jl: Fixed 2 identical mathematical expressions - lib/OrdinaryDiffEqStabilizedIRK/src/irkc_perform_step.jl: Fixed 3 complex mathematical expressions in IRKC implementation - lib/OrdinaryDiffEqIMEXMultistep/src/imex_multistep_perform_step.jl: Fixed 2 function combinations for fsalfirst - lib/OrdinaryDiffEqRosenbrock/src/rosenbrock_perform_step.jl: Fixed 1 array operation expression - lib/OrdinaryDiffEqCore/src/dense/generic_dense.jl: Fixed 2 complex differential variable expressions - test/interface/utility_tests.jl: Fixed 1 array operation in lambda function All changes follow Catalyst.jl PR #1306 guidelines to improve readability by keeping semantically related expressions on single lines while staying under 120 character limits.
