Summary

OpenCode's TSX sources were reaching Perry's React-style JSX path and Solid's non-reactive server modules. Compile them with the Solid universal renderer selected by the nearest tsconfig.json or an explicit perry.jsx.runtime, and select Solid's client builds throughout the graph.

Changes

  • Read jsxImportSource from JSONC tsconfigs, including inherited settings, and support { "runtime": "@opentui/solid" } in package/TOML configuration. Preserve the existing "solid" and "default" modes and track configuration inputs for caching.
  • Emit static properties, tracked property effects with previous values, text nodes, child accessors and insertion markers, component getters, refs, directives, ordered spreads and fragments. Resolve lexical bindings so constant/imported callback refs never gain invalid assignment fallbacks.
  • Resolve Solid core/store to their client builds across dependencies, re-exports and initialization ordering, preserving nested package instances. Recollect if a nested JSX package activates Solid after earlier imports were resolved. Select OpenTUI's Bun entry only in Bun platform mode.
  • Add a pinned OpenTUI differential fixture, a native Solid renderer fixture, configuration regressions and documentation.

Fixes #10099.

Test plan

  • Coherent perry-dev build of perry, perry-runtime-static and perry-stdlib-static, using --no-default-features --features perry/dev-cli.
  • HIR Solid tests: 4 passed.
  • CLI Solid configuration/resolver unit tests: 4 passed; existing tsconfig resolver tests: 11 passed.
  • solid_jsx_config CLI integration tests: 8 passed, including cache/config switches and nested-package recollection.
  • compare.py with the built compiler and OpenCode v1.18.30 (3104c1428ec91f809e5ab86631300de41eb6952e): semantic fixture agrees with the real OpenTUI Babel transform; identical OpenTUI character frames before/after updates; native fixture passes with reactive core/store and exactly five native modules; all 110 TSX files in both source trees pass both transforms and HIR lowering without fallback jsx()/jsxs() references.
  • Existing perry-solid JSX behavioral fixture passes through the new expansion under Bun.
  • Changed Rust files pass rustfmt; scripts/check_file_size.sh, scripts/check_node_version_consistency.py --list and git diff --check pass.

Native validation ran on Windows with PERRY_RS4GC=0 for the existing LLVM WinEH limitation (#7354), using freshly rebuilt matching archives. The OpenTUI frame comparison executes both expansions under Bun; the native executable uses the real solid-js/universal renderer with a deterministic headless host.

The full OpenCode native TUI first frame is not claimed here: runtime plugin inactivation and worker/runtime-plugin support remain paired work in #10100, #10103 and #10105. No Babel transform or JavaScript engine is used by Perry's JSX compilation.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Refs and use: directives execute in reverse source order.

Both branches call result.statements.insert(0, ...) inside the attribute loop. Each later attribute is inserted in front of the earlier one. For <box use:first={a} use:second={b} />, the generated code runs second before first. The same inversion applies between a ref and a directive on the same element.

Solid's universal transform preserves source order for directives and applies the ref first. Collect these prologue statements in a separate vector, then prepend the vector once after the loop.

Bun install lockfile behavior package-lock.json bun.lock existing node_modules official documentation

💡 Result:

<search_synthesis>
When you run bun install, the tool manages lockfiles and node_modules based on the following behaviors: Lockfile Management and Migration - Default Lockfile: Bun currently uses a text-based lockfile named bun.lock [1][2]. - Migration: If you run bun install in a project that lacks a bun.lock but contains package-lock.json (from npm, version 2 or higher), yarn.lock (v1), or pnpm-lock.yaml, Bun will automatically migrate the existing lockfile to the bun.lock format, preserving existing resolutions [2]. It does not modify or delete the original lockfile [2]. - Legacy Binary Lockfiles: Prior to Bun 1.2, the default was a binary lockfile called bun.lockb [1][2]. You can migrate this to the new format by running bun install --save-text-lockfile --frozen-lockfile --lockfile-only, then manually deleting the old bun.lockb file [1][2]. - Opt-out: You can prevent the creation of a lockfile by using the --no-save flag [2]. Existing node_modules Behavior - Incremental Installs: If a node_modules folder exists, Bun checks it before installing [3]. If the folder already contains all expected packages with the versions required by your project, bun install completes without downloading or extracting tarballs [1][3]. - Performance: When updates are required, Bun downloads missing dependencies lazily and utilizes the global cache to minimize redundant downloads [1][3]. It uses efficient syscalls like hardlinks (Linux/Windows) or copy-on-write clonefile (macOS) to move packages from the global cache into node_modules [3]. Frozen Lockfile - To ensure reproducible builds, especially in CI environments, use the --frozen-lockfile flag [1][4]. This forces Bun to use the versions specified in bun.lock exactly as they are [1]. If your package.json conflicts with bun.lock, Bun will exit with an error [1][4]. Note that --frozen-lockfile is not enabled automatically in CI; you must pass the flag or use bun ci [1][4].

Bun installs `peerDependencies` by default. - Runs your project&`#39`;s `{pre|post}install` and `{pre|post}prepare` scripts at the appropriate time. For security reasons Bun does not execute lifecycle scripts of installed dependencies unless they are trusted. - Writes a `bun.lock` lockfile to the project root. ... `--production` implies `--frozen-lockfile`. It only controls what gets installed. `devDependencies` already in `node_modules` from an earlier install stay there. Use `bun prune --production` to remove them. ... For reproducible installs, use `--frozen-lockfile`. Bun installs the exact versions specified in the lockfile and does not update it. If your `package.json` disagrees with `bun.lock`, Bun exits with an error. ... Bun does not enable `--frozen-lockfile` automatically in CI; pass the flag or use `bun ci`. If there is no lockfile at all, `--frozen-lockfile` installs from `package.json` without writing one. ... `--frozen-lockfile` works on a pruned monorepo checkout (e.g. `turbo prune` output, or a Docker context with only some workspace folders copied in). If a workspace listed in `bun.lock` is missing its `package.json` on disk, Bun skips it with a `note:` and does not install its exclusive dependencies. If a remaining workspace depends on a skipped one, the install fails. ... validate the lockfile without installing, use `bun install --frozen-lockfile --dry-run`. ... See lockfile for more on `bun.lock`. ... A `configVersion` field in your lockfile controls the default. For a detailed explanation, see isolated installs. ... When the `node_modules` folder exists, Bun decides whether to install a package by checking that the `"name"` and `"version"` in its `package.json` at the expected `node_modules` location match the expected name and version. It uses a custom JSON parser which stops parsing as soon as it finds `"name"` and `"version"`. ... When a `bun.lock` doesn’t exist or `package.json` has changed dependencies, Bun downloads and extracts tarballs eagerly while resolving. ... When a `bun.lock` exists and `package.json` hasn’t changed, Bun downloads missing dependencies lazily.

Before Bun 1.2, the lockfile was binary and called `bun.lockb`. To upgrade an old lockfile to the new format, run `bun install --save-text-lockfile --frozen-lockfile --lockfile-only`, then delete `bun.lockb`. ... Bun migrates projects from pnpm automatically.

Yes #### Generate a lockfile without installing? To generate a lockfile without installing to `node_modules`, use the `--lockfile-only` flag. Bun always saves the lockfile to disk, even if it is already up to date with your project&`#39`;s `package.json`(s). The exception is when `--frozen-lockfile` (or `--production`) is set. ```bash bun install --lockfile-only ``` `bun add`, `bun remove`, and `bun update` also accept `--lockfile-only`. `--lockfile-only` still populates the global install cache with registry metadata and git/tarball dependencies. #### Can I opt out? To install without creating a lockfile: ```bash bun install --no-save ``` To write a Yarn lockfile in addition to `bun.lock`: ```bash bun install --yarn ``` ```toml [install.lockfile] # whether to save a non-Bun lockfile alongside bun.lock # only "yarn" is supported print = "yarn" ``` #### Text-based lockfile Bun v1.2 changed the default lockfile format to the text-based `bun.lock`. To migrate an existing binary `bun.lockb`, run `bun install --save-text-lockfile --frozen-lockfile --lockfile-only` and delete `bun.lockb`. For more on the format, see the blog post. #### Automatic lockfile migration When you run `bun install` in a project without a `bun.lock`, Bun automatically migrates existing lockfiles: - `yarn.lock` (v1) - `package-lock.json` (npm, `lockfileVersion` 2, 3 or 4) - `pnpm-lock.yaml` (pnpm) Bun does not migrate a `package-lock.json` from npm 6 or older (`lockfileVersion` 1); it prints a warning and resolves from `package.json` instead. Bun preserves the original lockfile. You can remove it manually after verification. <title>Global cache | Bun Docs</title> https://bun.com/docs/pm/global-cache Global cache | Bun Docs # Global cache How Bun stores and manages packages in its global cache Bun stores every package downloaded from the registry in a global cache at `~/.bun/install/cache`, or the path set by the `BUN_INSTALL_CACHE_DIR` environment variable. Packages live in subdirectories named like `${name}@${version}`, so Bun can cache multiple versions of a package. Configuring cache behavior bunfig.toml ``` [install.cache] # the directory to use for the cache dir = "~/.bun/install/cache" # when true, don&`#39`;t load from the global cache. # Bun may still write to node_modules/.cache disable = false # when true, always resolve the latest versions from the registry disableManifest = false ``` Copy to clipboard ## Minimizing re-downloads# When installing a package, if the cache already contains a version in the range specified by `package.json`, Bun uses the cached copy instead of downloading it again. Installation details If the semver version has a pre-release suffix (`1.0.0-beta.0`) or a build suffix (`1.0.0+20220101`), Bun replaces the suffix with a hash of that value instead, to reduce the chance of errors from long file paths. When the `node_modules` folder exists, before installing, Bun checks that `node_modules` contains all expected packages with appropriate versions. If so, `bun install` completes. Bun uses a custom JSON parser which stops parsing as soon as it finds `"name"` and `"version"`. If a package is missing or has a version incompatible with the `package.json`, Bun checks for a compatible module in the cache. If the cache has one, Bun installs it into `node_modules`. Otherwise, Bun downloads the package from the registry, then installs it. ## Fast copying# Once a package is downloaded into the cache, Bun still needs to copy those files into `node_modules`. It uses the fastest syscalls available for this: hardlinks on Linux and Windows, `clonefile` on macOS. ## Saving disk space# On Linux and Windows, Bun uses hardlinks to "copy" a module into a project&`#39`;s `node_modules` directory, so the contents of the package only exist in a single location on disk. This greatly reduces the disk space used by `node_modules`. The same applies on macOS, with a caveat. There Bun uses `clonefile`, which is copy-on-write: the clone occupies no extra disk space, but it counts towards the drive&`#39`;s limit. Because the copy only happens on write, patching `node_modules/*` in one project can&`#39`;t affect other installations. Installation strategies Configure this with the `--backend` flag, which all of Bun&`#39`;s package management commands respect. - `hardlink`: Default on Linux and Windows. - `clonefile`: Default on macOS. - `clonefile_each_dir`: Similar to `clonefile`, except it clones each file individually per directory. It is only available on macOS and tends to perform slower than `clonefile`. - `copyfile`: The fallback used when any of the above fail. It is the slowest option. On macOS, it uses `fcopyfile()`; on Linux it uses `copy_file_range()`. - `symlink`: Symlinks each file instead of copying it.

Use a clean workspace and the checked-in lockfile.

compare.py reuses work/ and omits package-lock.json. Therefore, bun install can reuse stale bun.lock or node_modules state, or resolve from package.json without the checked-in npm lockfile. Match fixture.sh by removing work/, copying package-lock.json, and using npm ci.

Proposed fix
 work = fixture / "work"
-work.mkdir(exist_ok=True)
-for name in ["package.json", "tsconfig.json", "host.ts", "main.tsx", "frames.tsx", "oracle.mjs"]:
+if work.exists():
+    shutil.rmtree(work)
+work.mkdir()
+for name in ["package.json", "package-lock.json", "tsconfig.json", "host.ts", "main.tsx", "frames.tsx", "oracle.mjs"]:
     shutil.copy2(fixture / name, work / name)
 
-run(["bun", "install", "--ignore-scripts"])

Build the Perry compiler before using --perry.

The perry-hir example build does not build the separate perry binary. compare.py executes target/perry-dev/perry when --perry is provided, so the documented sequence fails from a clean checkout. Add the standalone compiler build:

Neither PR is wrong on its own; both breaks only exist once the twelve land
together, which is what the train is for.

- `module_require/dynamic_import_tests.rs` (#10131) called
  `js_module_dynamic_import_fallback` and `js_module_dynamic_import_deferred`
  at their old arity. #10128 gave both an `options` parameter for import
  attributes (`import(path, { with: { type: "toml" } })`), so the three test
  call sites now pass `undefined()` for it. Test-only; no behaviour change.

- `compile/solid_config.rs` (#10135) declares `JsxMode` as `pub(super)` while
  `CompilationContext::solid_jsx` exposes it as a `pub` field on a
  `pub(crate)` struct, which is a private-interface violation and fails the
  product scope under `-D warnings`:

      type `JsxMode` is more private than the item
      `compile::types::CompilationContext::solid_jsx`

  Widened to `pub(crate)` to match its own exposure.

Landed on main via merge train #10139 (rebase-merged, per-commit authorship preserved).

Your commits are on main starting at 8b282192fa; the train tree was verified identical to main after the merge (git diff origin/main HEAD --stat empty).

Two things needed fixing to land alongside the others. (1) JsxMode is declared pub(super) while CompilationContext::solid_jsx exposes it as a pub field on a pub(crate) struct — a private-interface violation that fails the product scope under -D warnings (cargo check -p perry --bins). Widened to pub(crate); worth checking, since that would have reddened CI's warnings job on its own. (2) Your tsconfig.json addition to the build-cache key list collided with #10129's perry.json; both kept, since each is a cache key.

Closing as landed — GitHub cannot auto-close through a train branch.
