App-GHGen-0.06

Changes for version 0.06 - 2026-07-17

Bug Fixes
- Approved https://github.com/nigelhorne/App-GHGen/pull/6 Missing unescaped $ failed to interpolate variable into double-quoted string Thanks to https://github.com/chromatic
- Fixed enable_linter_unused having no effect when set to 1 via the non-interactive code path. The POD Params::Validate block (default => 0) is documentation only; the actual runtime default was the // 0 on the assignment line (line 286). Changed to // 1.
New Features
- Added Perl syntax linting step to generated workflows (enable_linter, default: on) Uses shell: perl {0} so it runs cross-platform without OS-specific branching. Searches lib/ and bin/, uses do $file with a stub @INC handler for every .pm file, and covers every matrix cell (all OS × Perl version combinations). No extra CPAN dependencies required.
- Added unused-variable check (enable_linter_unused, default: on). The check is embedded inside the lint step and runs PERL5OPT=-Mwarnings::unused prove -lr t/ so variable lifetimes are exercised at runtime (perl -c is compile-only and cannot detect unused vars). Gated on RUNNER_OS == Linux and continue-on-error: true.
- Added import-hygiene check (enable_perlimports, default: on). Installs App::perlimports and runs perlimports --lint across all .pm files under lib/. Scoped to latest Perl + ubuntu-latest; continue-on-error: true so it is advisory rather than blocking.
- Both enable_linter_unused and enable_perlimports are exposed in the interactive --customize prompt for Perl workflows under the "Code Quality Tools" heading.
- Regression test added in t/pull_6.t for the PR #6 cost-display bug fix.
- Tests added/extended in t/linter.t covering presence/absence, ordering, and platform-gating of all lint-stage steps.
- Added t/extended_tests.t: 99 branch-coverage tests targeting uncovered paths across all 8 modules (Analyzer, CostEstimator, Detector, Fixer, Generator, Interactive, PerlCustomizer, Reporter). Flags Analyzer::has_deployment_steps as dead code (defined but not exported and not called from analyze_workflow).
CI Matrix
- Default Perl matrix is now 5.36, 5.38, 5.40, 5.42 (max_perl_version bumped from 5.40 to 5.42). Perl::Critic, perlimports, and coverage steps are now gated on 5.42 (always the latest version in the matrix).
- Perl 5.44 added to the known-versions table as an opt-in. Projects wanting to test against 5.44 before it becomes the default can pass max_perl_version => '5.44' to generate_custom_perl_workflow, or set perl_versions explicitly. No code change needed on the caller's side.
- POD for generate_custom_perl_workflow updated: max_perl_version default corrected to 5.42, opt-in examples for 5.44 added under the max_perl_version item.
