Use `frg replace` for codebase-wide search and replace. Shows a diff preview by default, applies changes with `--write`. Works on unindexed trees — no `frg index` required.
Performs batch find-and-replace using sd CLI (sed alternative) for variable renames, import updates, regex patterns, and string replacements across files with safe preview workflows.
Builds srgn CLI commands for syntax-aware source-code search, transformation, scoped refactors, and CI checks. Use for multi-file rewrites, tree-sitter queries, or lint-like validations.
Searches codebases using ripgrep (rg) with regex patterns, file type/extension filtering, multi-line support, and .gitignore respect. Use for text patterns, code snippets, or multi-file analysis.
