fix(config): pick up pkl import changes that hk's config cache used to miss - #1422
Conversation
A `hk.pkl` using a pkl glob import did not pick up files newly added to
the matched directory until `hk.pkl` itself changed or `hk cache clear`
ran. pklr expands glob patterns to the files present at analysis time,
and only those expanded paths became the config cache's freshness
inputs, so a brand-new matching file was in neither list and was never
noticed.
Record the glob patterns themselves in `ImportAnalysis` alongside what
they expanded to. Before using a cached analysis, re-expand the recorded
patterns and re-analyze when the result differs, which covers files
added, removed, and renamed. Configs without glob imports return early
from that check and do no extra filesystem work.
Also merge the glob matches into `local_paths`. pklr's `collect_imports`
only sees the `import* "..." as name` declaration form, so with the
expression form `import*("...")` the matched files were absent from the
cache's freshness inputs entirely and editing one did not invalidate
either.

The imports cache is keyed on the root config file alone, so a cached `ImportAnalysis` kept describing the module graph as it used to be whenever an *imported* module changed its own imports. Two ways that goes wrong, both reproduced: - `other.pkl` gains an `import*` pattern. The edit invalidates the resolved config once, but the new pattern never enters the cached analysis, so files later added under it are silently omitted. - `other.pkl` starts importing `third.pkl`. `third.pkl` is absent from the recorded graph, so editing it does not invalidate anything. This one predates glob-import tracking. Record a digest of every source in the graph and re-analyze when it no longer matches, alongside the existing glob-expansion check. Both checks re-read only what the analysis already recorded. Measured on hk's own config (319 local sources, and `pkl/Builtins.pkl` is itself a glob importer): min-of-15 interleaved `hk validate` runs differ by 9ms, within noise.

A `hk.pkl` can now build its steps from a glob of other pkl files using
the
expression form of `import*`:
```pkl
local generated = import*("generated/*.pkl")
hooks {
["check"] {
steps = new Mapping<String, Step> {
for (_, mod in generated) {
...mod.STEPS
}
}
}
}
```
Each generated file contributes its own steps:
```pkl
// generated/prettier.pkl
import "package://github.com/jdx/hk/releases/download/v2.0.1/hk@2.0.1#/Config.pkl"
STEPS: Mapping<String, Config.Step> = new {
["prettier"] {
glob = List("*.md")
check = "echo prettier {{files}}"
}
}
```
With `generated/prettier.pkl` and `generated/shellcheck.pkl` on disk:
```
$ hk check --all
✔ files - Fetching all files in repo (7 files)
prettier – 1 file – *.md – echo prettier a.md
shellcheck – 1 file – *.sh – echo shellcheck b.sh
✔ shellcheck
✔ prettier
```
This is the setup in jdx/pklr#192: configurations assembled from
generated or
templated step definitions. hk's evaluator used to reject the expression
form at
parse time with `unexpected token in expression: KwImportStar`, which
kept those
projects on hk 1.x. The module-level declaration form, `import*
"generated/*.pkl"
as generated`, already worked and still does.
The support comes from pklr 3.0.0 (jdx/pklr#195). That release is major
only
because pklr's public AST enums gained variants and were marked
`#[non_exhaustive]`;
hk uses `AsyncEvaluatorBuilder`, `analyze_imports_async`, `Result`, and
the
`reqwest` re-export, none of which changed.
## Untracked remote imports
pklr 3 also allows `import(...)` anywhere an expression is allowed,
which reaches
a cache bug in hk. `Config::source_may_reference_untracked_import`
decides whether
a config pulls in a module hk cannot hash, and it only matched lines
*starting*
with `amends`/`extends`/`import`/`import*`, with the URI on that same
line. A
remote module reached from an expression slipped past it:
```pkl
local step = import("https://example.com/Step.pkl")
```
hk then treated the config as fully local-content-trackable and served
it from the
shared `resolved-config.json`, so a change to the remote module went
unnoticed
until an unrelated local `.pkl` edit or `hk cache clear`.
The scan now strips comment lines and matches each keyword to the string
literal
that follows it, so it also handles a URI on a later line, a comment
between the
keyword and its URI, and the multiline string literal that pklr parses
even though
Apple Pkl rejects it. Tying the URI to its own keyword additionally
removes a false
positive the line-based version had, where an unrelated remote URL sat
on the same
line.
## Validation
`cargo build --release`, `mise run test:cargo` (349 tests), and `cargo
fmt --check`
pass. The `hk check` output above was produced by this branch against
the published
pklr 3.0.0.
New coverage: `test/config_glob_imports.bats` exercises the expression
and
declaration forms, an empty match, and cache invalidation after editing
a matched
file — bats runs with `HK_CACHE=1`, so that last case hits the real
cache path. All
four pass under the libgit2, nolibgit2, and nogit backends, and
`scripts/validate-apple-pkl.py` evaluates every fixture with Apple Pkl
0.32.1.
`untracked_import_detection_covers_declarations_and_expressions` in
`src/config.rs`
covers the scan above, including the multiline, wrapped and commented
forms, each
verified to evaluate in both Apple Pkl 0.32.1 and pklr 3.0.0 before
being encoded
as a test.
This branch merges `main` at ac5c78a (#1422), which made glob
membership a cache
freshness input. Verified after the merge: adding
`generated/yamllint.pkl` to the
example above is picked up on the next `hk check` with no edit to
`hk.pkl` and no
`hk cache clear`. `test/cache_behavior.bats` passes here too.

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Touches Pkl evaluation (major pklr bump) and config cache eligibility
logic; incorrect untracked-import detection could still cause stale or
over-conservative caching.
>
> **Overview**
> Upgrades **pklr** from 2.x to **3.0.0** so `hk.pkl` can use the
**expression** form of glob imports (`local generated =
import*("generated/*.pkl")`), which previously failed at parse time
while the declaration form already worked.
>
> **Fixes config cache safety** for remote modules loaded via
expression-style `import` / `import*`:
`source_may_reference_untracked_import` no longer only inspects
line-leading keywords with URIs on the same line. It now finds the
string literal after each `amends`, `extends`, or `import` (including
`import*`) across comments, line breaks, and supported string forms, so
configs that pull in `http`/`https`/`package://` modules are not
incorrectly treated as fully hashable for shared cache.
>
> Adds **docs** for the generated-step pattern (`STEPS` mappings,
expression vs declaration `import*`) and **integration tests** for
glob-defined steps, empty globs, and cache invalidation when a matched
file changes.

Problem
hk caches its analysis of a config's module graph, keyed on the root
hk.pklalone. That key is too narrow in two ways, and both let a stale config run silently.1. Glob imports don't notice new matches. A project that generates step definitions into a directory and pulls them in with a glob:
With only
generated/one.pklpresent,hk check --allran stepone. Addinggenerated/two.pkland re-running still ran onlyone—twoappeared only after editinghk.pklor runninghk cache clear. Pkl glob patterns expand to the files that exist at analysis time, and hk stored only those expanded paths as freshness inputs, so a brand-new matching file was in neither list.2. Edits inside the graph don't refresh the graph. Because the cached analysis is keyed on the root config, an imported module that changed its own imports left the recorded graph describing the config as it used to be:
other.pklgains animport*pattern. The edit invalidates the resolved config once, but the new pattern never enters the cached analysis, so files later added under it stay invisible indefinitely.other.pklstarts importingthird.pkl.third.pklis absent from the recorded graph, so editingthird.pklinvalidates nothing. This one predates glob-import tracking.What changed
ImportAnalysisnow records two more things and validates them before a cached entry is used:Both checks re-read only what the analysis already recorded, so neither needs the answer it is trying to compute.
Glob matches are also merged into
local_paths. pklr's import collector only recognizes theimport* "..." as namedeclaration form, so with the expression formimport*("...")the matched files were absent from the freshness inputs entirely and editing one did not invalidate either. hk now collects both forms itself using pklr's lexer.Performance
hk validateagainst hk's own config — 319 local sources, andpkl/Builtins.pklis itself a glob importer, so both new checks are exercised — over 15 interleaved runs of a binary built with and without the digest check: min 1.929s vs 1.938s, a 9ms difference in favor of the new code, i.e. within noise on this machine. Hashing the graph is negligible against pkl evaluation, and the config cache already reads the same files to build its own key.Adoption
No new flags or settings, and no config changes are needed. Caches written by older hk versions are keyed by hk version and are not reused.
The expression form
import*("...")still does not evaluate under the pinned pklr 2.0.5 (unexpected token in expression: KwImportStar); the parsing side here handles it so it is covered when hk moves to pklr 3.x. The added documentation shows only the declaration form, which is what currently evaluates.Docs
docs/pkl_introduction.mdgained an "Import many files at once" section coveringimport*and stating that the pattern is resolved on every run. The task this came from referred to an existing caveat in that file documenting the limitation; no such section existed onmain, so this adds the feature documentation rather than editing a caveat.Validation
Each scenario was reproduced against the unfixed binary first, then confirmed fixed:
hk.pklimport*, then a file is added under ittest/cache_behavior.bats. Each was confirmed to fail against the code it fixes by stubbing out the corresponding check — exactly the intended tests went red, no others.config::testscovering both import syntaxes, glob add/remove/non-matching-file staleness, transitive source edits and deletions, and the unchanged-config path.cargo test: 341 passed, 0 failed.hk check --all --slow: clean.
