Mult

Problem

Developer workflows accumulate one-off scripts: slugify a batch of filenames, strip duplicates, resize images, audit permissions. Each script has its own flags, error shape, and dry-run behavior. Consistency disappears; muscle memory replaces design.

Mult registers discrete operations behind a shared core contract so new capabilities plug in without rewriting the CLI shell.

Operation families

• Rename transforms — slugify, regex replace, sequential numbering, CSV-driven batches, and metadata-aware renames
• Media and document ops for image, video, audio, and document pipelines
• Analysis and security passes over filesystem trees
• Archive and cleanup helpers for bulk maintenance
• Plugin-style registration via core.DefaultRegistry with category and audience metadata

type slugifyOp struct{}

func (o slugifyOp) Name() string            { return "slugify" }
func (o slugifyOp) Description() string     { return "convert filenames to URL-safe slugs" }
func (o slugifyOp) Category() core.Category { return core.CategoryRename }

func (o slugifyOp) Execute(_ context.Context, entry core.FileEntry, _ core.Options) (core.Result, error) {
    stem, extension := splitStemExtension(entry.Name)
    newStem := filename.Slug(stem)
    return renameResult(entry, newStem+extension, "already slugified"), nil
}

func init() { core.DefaultRegistry.Register(slugifyOp{}) }
