Note

Medium Risk
Changes affect cross-command flag prefix binding and multi-shell completion semantics; behavior is covered by new tests but still touches core parse and completion paths.

Overview
6.x release documentation is marked done in PLAN.md: limitations are aligned with the compatibility matrix, stale claims are dropped, and public snippets now point at usage / clap_usage 6 (including completions and clap integration docs). Runtime/version identity wording in docs/rust/spec.md is tightened around version_spec vs computed --version.

clap → usage spec generation now clones and build()s the command with help/version subcommands disabled so action-derived metadata (e.g. append arity) is visible to fidelity reporting without leaking clap’s implicit help into the spec; the caller’s Command is left unchanged and declared disable_* settings are restored recursively. Snapshots/tests reflect specs without a bare flag --usage and with default="false" where appropriate.

Shell completion behavior treats text after a restart token (:::) like a fresh invocation for command_args (commands again, then arbitrary paths), in both argv completion and complete_word (after_restart_token). Zsh executable completion switches from *(*) to *(-/,*) so directories stay offered alongside executables (Rust/Go script generators updated).

Parsing records negation on prefix flag bindings so an inferred --no-cl prefix stays bound to the ancestor flag across subcommand redeclaration instead of losing negation when the child redefines the same flag.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds executable and command completion across CLI metadata and generated shell scripts. It also updates completion and clap integration documentation, and marks related parser, compatibility, migration, and API work complete in PLAN.md.

Changes

Command-aware completion

Layer / File(s) Summary
Restart-aware command completion
argv/src/complete.rs, cli/src/cli/complete_word.rs, cli/tests/complete_word.rs
Completion distinguishes command names from executable paths, tracks variadic values, handles restart tokens, discovers executables from PATH, and applies platform-specific matching.
Cross-shell completion markers
argv/src/script.rs
Bash, Zsh, Fish, Nushell, and PowerShell support separate executable and command completion markers with shell-specific discovery and filtering.

Project and integration documentation

Layer / File(s) Summary
Plan and integration documentation
PLAN.md, docs/rust/completions.md, docs/spec/integrations/clap.md
The plan records completed parser, compatibility, migration, API, runtime, and performance items. Documentation updates dependencies to version 6 and describes clap fidelity reports and lossless validation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 4bdc1

The PR changes shell completion behavior and updates 6.x documentation, but the current version can suggest invalid Nushell paths, mis-handle forwarded child flags, and invert a narrowly scoped negated option; several documentation examples also remain inaccurate. These bounded correctness issues should be fixed or explicitly accepted before merging.

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: markdown on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1, startup on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1

Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run.

Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

Shadow comparison

Parsing mise use -g node@20 against a shadow of mise's committed spec.
Reported, not gated: the shadow grows as the derive learns to express more, so
what to watch is the ratio rather than either column.

Bound the printed max_values in the ValueArity detail.

num_args(2..) and ArgAction::Append produce an open upper bound. range.max_values() then returns usize::MAX. The detail string renders num_args=2..=18446744073709551615, which is hard to read in a migration report.

Emit an open range when the upper bound is unbounded.

Assert the loss count before you index losses()[0].

The test indexes the first loss directly. If the report is empty, the test panics with an index-out-of-bounds message and does not show the report. If a future change adds a loss that sorts earlier, the test fails on the wrong entry.

Consider marking FidelityLoss as #[non_exhaustive].

FidelityFeature is already #[non_exhaustive]. FidelityLoss is a public struct with public fields and no such attribute. If a later release adds a field, for example a span or a severity, the change breaks downstream struct literals and exhaustive destructuring. This PR ships 6.0.0, so the attribute costs nothing now and preserves room to extend the report.

Remove the now-unreachable built-in fallbacks in long_flag.

find_long_form already returns (&HELP_LONG, false) for name == b"help" at Line 1714, and (&VERSION_LONG, false) for name == b"version" when self.cmd.version at Line 1717. The if let Some((flag, negated)) = self.find_long_form(name) branch at Line 1352 therefore always takes those cases. The two blocks at Lines 1373-1389 can no longer execute.

Leaving them in place duplicates the built-in precedence rule in two locations. A future change to one location would not change behavior, which hides the mistake.

Hoist the repeated inference lookups out of the parse loops.

out.cmds.iter().any(|cmd| cmd.infer_subcommands) and the infer_long_args equivalent appear at Lines 838, 898, 1154, 1229, and 1446. Each one walks the whole command chain, and Lines 1154 and 1229 run once per token.

Both values only change when out.cmds gains a command. Two mutable flags updated at each descent would remove the repeated walks and would keep the two Phase 2 call sites from drifting apart.

This is a readability and consistency improvement. The current cost is small.

Make the negative Nushell assertion less brittle.

glob qualifier; both sites require the identical change.

In `@clap_usage/src/generate.rs`:
- Around line 28-35: Update spec_with_report to call cmd.build() before invoking
report(cmd) and spec(cmd, bin_name), ensuring derived argument arity is
populated before both operations.

In `@cli/src/cli/complete_word.rs`:
- Around line 363-388: Update the command_args completion flow around
command_was_bound so that, when automatic positional collection is active and
the command word is already bound, dash-prefixed tokens are treated as forwarded
argument values before CLI flag routing. Preserve normal CLI flag completion for
unbound command_args and other non-forwarded contexts, while allowing path or
forwarded-argument fallback candidates for cases such as mycli usage -h.

In `@docs/rust/args-and-flags.md`:
- Line 87: Update the ValueHint::FilePath documentation table entry to describe
only file or path completion, removing wording that suggests command-name
completion; keep command-related wording reserved for CommandName,
CommandString, and CommandWithArguments.

In `@docs/rust/spec.md`:
- Around line 100-108: Update the documentation around Cli::runtime_app() to
describe that computed version values are formatted via ToString for --version
output while version_spec remains static, and that runtime_app() currently
applies only name and bin. Add .version(...) to the explicit override example,
unless runtime_app() is changed to apply the computed version as well.

In `@docs/spec/integrations/clap.md`:
- Around line 26-35: Update the migration guidance around spec_with_report and
generate_with_report to clarify that is_lossless() covers only losses detectable
through public clap getters. Instruct readers to audit the compatibility
matrix’s usage-only and lossy bridge rows against the Rust declaration before
treating the generated spec as fully compatible.

In `@lib/src/parse.rs`:
- Around line 1212-1221: Preserve the Phase 1 negation state for bound inferred
flags by storing the matched negation value in prefix_bindings and reusing it
during Phase 2 instead of relying on Arc::ptr_eq or the full-spelling fallback.
Update the flag-resolution logic around prefix_bindings and add a regression
test covering a mount redeclaration where --no-cl matches global --no-clean and
remains Bool(false).

---

Nitpick comments:
In `@argv/src/lib.rs`:
- Around line 1371-1395: Remove the redundant built-in help and version fallback
blocks from long_flag; find_long_form already handles these cases, so retain its
precedence behavior and leave the unknown_flags handling and word fallback
unchanged.

In `@argv/src/script.rs`:
- Around line 573-576: Update the assertion in the relevant test to verify
directly that wants_files does not contain the commands marker, rather than
matching the generated script’s exact newline and indentation. Keep the failure
message focused on the whitespace-independent wants_files property.

In `@clap_usage/src/lib.rs`:
- Around line 23-24: Mark the public FidelityLoss struct as #[non_exhaustive],
matching FidelityFeature, so future fields can be added without breaking
downstream struct literals or exhaustive destructuring.

In `@clap_usage/src/report.rs`:
- Around line 281-298: Update the ValueArity detail formatting in the range
handling around range.max_values() so an unbounded upper limit is rendered as an
open range instead of usize::MAX; preserve the existing bounded formatting and
action/minimum-value details.

In `@clap_usage/tests/fidelity_report.rs`:
- Around line 66-72: Update the test around spec_with_report and
FidelityFeature::AllowNegativeNumbers to first assert that report.losses()
contains exactly one entry, then inspect that sole loss without relying on an
unchecked index. Preserve the existing command, argument, and feature
assertions.

In `@docs/rust/performance.md`:
- Around line 15-28: Add benchmark provenance to the performance documentation:
include the benchmark command, measurement commit or specification revision,
release toolchain, and runner/OS details. Document that reported ratios are
calculated from unrounded measurements, including how the 238x wall-time ratio
corresponds to the displayed rounded values.

In `@lib/src/parse.rs`:
- Around line 1148-1158: Hoist the repeated infer_subcommands and
infer_long_args checks out of the parse loops by maintaining mutable inference
flags alongside command descent and updating them whenever out.cmds gains a
command. Reuse these flags at the resolve_long_flag call and the corresponding
subcommand-resolution sites, including the existing checks near the other
referenced locations, so Phase 2 uses consistent values without repeatedly
scanning out.cmds.

In `@lib/src/spec/cmd.rs`:
- Around line 784-791: Add a round-trip test alongside the existing
the_setting_survives_a_round_trip test in parse.rs covering both
infer_subcommands and infer_long_args, including a nested cmd. Serialize the
spec, parse the generated KDL again, and assert both inference settings remain
enabled after reparsing.

In `@usage-rs/tests/external.rs`:
- Around line 10-22: Remove the unnecessary output binding in the external
fixture command helper and return the chained Command::output result directly,
preserving the existing command arguments, environment, and expect message.

297-338: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Preserve executable-only filtering in Nushell.

Line 297 combines the files, dirs, and executables markers. When Line 338 returns null, Nushell performs generic path completion. Generic path completion includes non-executable files.

Keep executable-marker state separate. For executables, return only directories and executable files. Do not use the generic path fallback.
