Add lib/salesforce/ with two new helpers:

  • mkSfPlugin builds an oclif plugin from its npm registry tarball,
    stripping dev dependencies to work around incomplete shrinkwrap files
  • sfWithPlugins relinks the Salesforce CLI with plugins as core
    plugins so they resolve from the store instead of mutable user data

Add two new packages sf-plugin-code-analyzer and sfdx-git-delta,
update package count badge to 44, and document the new library and
withPlugins usage in CLAUDE.md and README.md.

feat(pkgs): add Salesforce CLI plugin infrastructure and new plugins

  • Introduce mkSfPlugin and sfWithPlugins helpers from lib/salesforce
    to support composable SF CLI plugin packaging
  • Refactor salesforce-cli to expose runtimeEnv, withPlugins passthru
    and extract env-wrapping logic for reuse by plugin wrappers
  • Add sf-plugin-code-analyzer package (v5.16.0) with JDK21 and Python3
    runtime inputs for PMD, SFGE, ApexGuru and Flow engine support
  • Add sfdx-git-delta package (v6.45.1) for generating delta packages
    from git diffs

This adds Salesforce CLI plugin packaging and composition, but plugins using version-1 npm lockfiles can fail to build during lockfile sanitization. The issue is bounded to unsupported lockfile shapes and should be resolved before broad plugin-builder use.

🟡 Changes recommended

lib/salesforce/default.nix is prone to infinite recursion when callPackage auto-fills the sfWithPlugins argument for with-plugins.nix, which can break evaluation/builds.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR adds a small Salesforce-focused Nix library (lib/salesforce) to package oclif-based Salesforce CLI plugins from the npm registry and to produce a salesforce-cli.withPlugins variant that links those plugins as core plugins from the Nix store.

Changes:

  • Add mkSfPlugin and sfWithPlugins helpers under lib/salesforce/ and wire them into pkgs/default.nix.
  • Refactor salesforce-cli to expose runtimeEnv and a withPlugins passthru for composing plugins.
  • Add two new plugin packages (sf-plugin-code-analyzer, sfdx-git-delta) and update docs/README accordingly.

57-61: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Handle both npm lockfile names in mkSfPlugin.

mkSfPlugin accepts oclif plugins from npm, but postPatch always reads npm-shrinkwrap.json. If another supported tarball contains only package-lock.json, the patch step fails before npm ci with a missing-file error. The two pinned plugins currently contain npm-shrinkwrap.json, so this is a contract gap for other inputs.

♻️ Select the available lockfile
+      if [ -f npm-shrinkwrap.json ]; then
+        lockfile=npm-shrinkwrap.json
+      elif [ -f package-lock.json ]; then
+        lockfile=package-lock.json
+      else
+        echo "mkSfPlugin requires npm-shrinkwrap.json or package-lock.json" >&2

36-37: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Set pname and version on the composed CLI, and drop the inherited updateScript.

withPlugins is a documented consumer-facing package output. It currently exposes neither pname nor version, so consumers that read salesforce-cli.withPlugins [...].version get an evaluation error. Its merged passthru also retains the base package's updateScript, which advertises the composed derivation as independently updatable even though updates target pkgs/salesforce-cli/default.nix.

♻️ Proposed fix
     inherit (salesforce-cli) meta;
-    passthru = salesforce-cli.passthru // {
+    inherit (salesforce-cli) pname version;
+    passthru = removeAttrs salesforce-cli.passthru [ "updateScript" ] // {
       inherit plugins;

Make sfWithPlugins recurse through a let binding instead of taking itself
as a callPackage argument, expose pname/version on the composed CLI and
drop the base package's updateScript from it, and accept either npm
lockfile name in mkSfPlugin.

All three review comments addressed in 15ccd17.

lib/salesforce/with-plugins.nixpname/version and updateScript (CodeRabbit)

Confirmed: (salesforce-cli.withPlugins [ ... ]).version raised a missing-attribute error, since runCommand only sets name. Now inherits pname, version and meta from the base package, and drops updateScript from the merged passthru so the composition is not advertised as independently updatable.

{ hasUpdateScript = false; name = "salesforce-cli-2.149.9"; pname = "salesforce-cli"; version = "2.149.9"; }

lib/salesforce/plugin.nix — lockfile name (CodeRabbit)

postPatch now selects npm-shrinkwrap.json or package-lock.json, whichever the tarball ships, and fails with a named error if neither is present. Both pinned plugins ship a shrinkwrap, so npmDepsHash is unchanged for them.

lib/salesforce/default.nixsfWithPlugins self-reference (Copilot)

Answered inline: it evaluated correctly, but the file no longer relies on autoArgs for it.

Verified after the changes: nix flake check passes, and on the nested composition (cli.withPlugins [ sfdx-git-delta ]).withPlugins [ sf-plugin-code-analyzer ], with PATH=/usr/bin:/bin so the bundled JDK is the only one reachable:

sf plugins --core      → code-analyzer 5.16.0 (core), sfdx-git-delta 6.45.1 (core)
sf sgd source delta    → runs
sf code-analyzer run   → 3 PMD violations on a sample Apex class

The dev prune walks .packages, which lockfileVersion 1 does not have, so
the jq filter failed on null instead of reporting the unsupported input.
