PowerShell Script Analyzer: Good, consistent and pretty code
summary
PSScriptAnalyzer lints PowerShell by walking the AST inspection and applying built‑in and custom rules; several rules expose a fix parameter so the analyzer can auto-fix suggestions like replacing aliases, reindenting, or remove trailing whitespace. Demo runs on a ~4,000‑line script show the fixer removed 503 trailing spaces; an experimental repo tool generates one commit per file with fixes (testing it on a 120,000‑line codebase succeeded but the customer asked not to run it again). Integration into CI and editor formatting also works.
