From 5b48989edcc6d1171e8094c27dfb70cd63c1bb5a Mon Sep 17 00:00:00 2001 From: Edmund Miller Date: Fri, 15 Aug 2025 17:19:59 -0500 Subject: [PATCH 1/2] feat: Add extension point interfaces for standalone plugin development MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add PluginExtensionPoint base interface for all plugin extensions - Add Factory annotation for channel factory extensions - Add Function annotation for custom function extensions - Add Operator annotation for channel operator extensions - Add CommandExtensionPoint interface for first-class CLI commands These interfaces enable standalone plugin development by providing compile-time access to Nextflow extension points without requiring the full Nextflow runtime as a dependency. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../extensions/CommandExtensionPoint.groovy | 72 +++++++++++++++++++ .../nextflow/gradle/extensions/Factory.groovy | 36 ++++++++++ .../gradle/extensions/Function.groovy | 36 ++++++++++ .../gradle/extensions/Operator.groovy | 36 ++++++++++ .../extensions/PluginExtensionPoint.groovy | 56 +++++++++++++++ 5 files changed, 236 insertions(+) create mode 100644 src/main/groovy/io/nextflow/gradle/extensions/CommandExtensionPoint.groovy create mode 100644 src/main/groovy/io/nextflow/gradle/extensions/Factory.groovy create mode 100644 src/main/groovy/io/nextflow/gradle/extensions/Function.groovy create mode 100644 src/main/groovy/io/nextflow/gradle/extensions/Operator.groovy create mode 100644 src/main/groovy/io/nextflow/gradle/extensions/PluginExtensionPoint.groovy diff --git a/src/main/groovy/io/nextflow/gradle/extensions/CommandExtensionPoint.groovy b/src/main/groovy/io/nextflow/gradle/extensions/CommandExtensionPoint.groovy new file mode 100644 index 0000000..5308db9 --- /dev/null +++ b/src/main/groovy/io/nextflow/gradle/extensions/CommandExtensionPoint.groovy @@ -0,0 +1,72 @@ +/* + * Copyright 2013-2024, Seqera Labs + * + * Licensed under the Apache License, Version 2.0 (the "License");
