//! `ull install <version> --loader <kind> [--loader-version <v>]`:加载器层的编排。
|
||
//!
|
||
//! ```text
|
||
//! 目标解析:<version> 位是原版版本 → 叠原版;是已装的加载器版本 id → 叠在它上面(仅 LiteLoader)
|
||
//! → LoaderSource::resolve(官方 meta:版本列表 → profile JSON / installer profile / LiteLoader 版本表)
|
||
//! → LoaderInstallPlan::build(纯计算:库清单 + loader 版本 JSON 落点)
|
||
//! → [--dry-run 到此为止,但多带一段 processors 计划]
|
||
//! → 原版已装?否 → vanilla::plan_and_install(先装原版)
|
||
//! → 需要 installer?→ 依赖库 → 选 Java → 串行跑 processors(M35)
|
||
//! → execute(loader 库并发下载 → 全量就绪才写 versions/<loader-id>/<loader-id>.json)
|
||
//! → register(实例 versionId 指向 loader 版本)
|
||
//! ```
|
||
//!
|
||
//! 「先装原版」是**硬前置**:loader 版本 JSON 只声明 `inheritsFrom`,jar 与资源都在原版那层,
|
||
//! 原版缺失时启动链必然断裂。已装则跳过(`is_version_installed` 判据 = 版本 JSON 在盘上)。
|
||
//!
|
||
//! **父版本**:`<version>` 位写成加载器版本 id(`1.12.2-forge-14.23.5.2860`)时,它就是父版本,
|
||
//! 原版版本从盘上的继承链读出来(`addon::loader::parent`)。只有 LiteLoader 接受这种叠法
|
||
//! (它靠 `--tweakClass` 追加生效);别家**具名拒绝**,不会默默改成叠原版。
|
||
//!
|
||
//! processors 段的顺序也是硬约束:**先跑 processors,再写版本 JSON**。版本清单存在是
|
||
//! "这版装完了"的判据,抢在 processors 前写会留下一个启动必崩却被报成已安装的实例。
