From 06914549397f89c8234a6a468082bfa63cee9886 Mon Sep 17 00:00:00 2001 From: ChrisRackauckas Date: Sun, 3 Aug 2025 12:38:11 -0400 Subject: [PATCH 1/6] Move Moshi.jl clock functionality to extension MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change converts Moshi.jl from a required dependency to an optional extension, significantly reducing the dependency burden while maintaining full functionality when Moshi is available. ## Changes: - Move Moshi.jl from deps to weakdeps in Project.toml - Create SciMLBaseMoshiExt extension for pattern matching functionality - Replace direct Moshi usage in clock.jl with basic struct implementations - Update MLStyle extension to not require Moshi directly - Modify tests to work with both basic and Moshi implementations - Export individual clock types instead of Clocks module ## Benefits: - Reduced dependency load for users who don't need pattern matching - Maintains backwards compatibility - Preserves all existing functionality when Moshi is loaded - Cleaner separation of concerns 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Project.toml | 3 +- ext/SciMLBaseMLStyleExt.jl | 4 +- ext/SciMLBaseMoshiExt.jl | 82 ++++++++++++++++++++++++++++++++++++++ src/SciMLBase.jl | 4 +- src/clock.jl | 71 ++++++++++++++++++--------------- test/clock.jl | 25 ++++++------ 6 files changed, 137 insertions(+), 52 deletions(-) create mode 100644 ext/SciMLBaseMoshiExt.jl diff --git a/Project.toml b/Project.toml index 92b029a3a..c575a508e 100644 --- a/Project.toml +++ b/Project.toml @@ -18,7 +18,6 @@ IteratorInterfaceExtensions = "82899510-4779-5014-852e-03e436cf321d" LinearAlgebra = "37e2e46d-f89d-539d-b4ee-838fcccc9c8e" Logging = "56ddb016-857b-54e1-b83d-db4d58db5568" Markdown = "d6f4376e-aef5-505a-96c1-9c027394607a" -Moshi = "2e0e35c7-a2e4-4343-998d-7ef72827ed2d" PrecompileTools = "aea7be01-6a6a-4083-8856-8a6e6704d82a" Preferences = "21216c6a-2e73-6563-6e65-726566657250" Printf = "de0858da-6303-5e67-8744-51eddeeeb8d7" @@ -37,6 +36,7 @@ ChainRules = "082447d4-558c-5d27-93f4-14fc19e9eca2" ChainRulesCore = "d360d2e6-b24c-11e9-a2a3-2a2ae2dbcce4" MLStyle = "d8e11817-5142-5d16-987a-aa16d5891078" Makie = "ee78f7c6-11fb-53f2-987a-cfe4a2b5a57a" +Moshi = "2e0e35c7-a2e4-4343-998d-7ef72827ed2d" PartialFunctions = "570af359-4316-4cb7-8c74-252c00c2016b" PyCall = "438e738f-606a-5dbb-bf0a-cddfbfd45ab0" PythonCall = "6099a3de-0909-46bc-b1f4-468b9a2dfc0d" @@ -47,6 +47,7 @@ Zygote = "e88e6eb3-aa80-5325-afca-941959d7151f" SciMLBaseChainRulesCoreExt = "ChainRulesCore" SciMLBaseMLStyleExt = "MLStyle" SciMLBaseMakieExt = "Makie" +SciMLBaseMoshiExt = "Moshi" SciMLBasePartialFunctionsExt = "PartialFunctions" SciMLBasePyCallExt = "PyCall" SciMLBasePythonCallExt = "PythonCall" diff --git a/ext/SciMLBaseMLStyleExt.jl b/ext/SciMLBaseMLStyleExt.jl index 8b255f020..09b120911 100644 --- a/ext/SciMLBaseMLStyleExt.jl +++ b/ext/SciMLBaseMLStyleExt.jl @@ -11,7 +11,7 @@ module SciMLBaseMLStyleExt using SciMLBase: TimeDomain, ContinuousClock, SolverStepClock, PeriodicClock using MLStyle: MLStyle using MLStyle.AbstractPatterns: literal, wildcard, PComp, BasicPatterns, decons -using Moshi.Data: isa_variant +# Removed Moshi dependency -
