Sigra.Organizations.Slug (Sigra v0.2.2)

Slug generation and validation for organizations.

Validates slug format (D-07), length (D-07), and reserved words (D-08). The reserved word list is hardcoded in the library with an additive extension point via additional_reserved_slugs config.

Summary

Functions

default_reserved_slugs()

Returns the default reserved slug list.

generate(name)

Phase 16 Plan 03 alias for generate_slug/1.

generate_slug(name)

Generates a slug from a name string.

validate_slug(changeset, config)

Validates the :slug field on a changeset.

Functions

default_reserved_slugs()

@spec default_reserved_slugs() :: [String.t()]

Returns the default reserved slug list.

generate(name)

@spec generate(String.t() | nil) :: String.t() | nil

Phase 16 Plan 03 alias for generate_slug/1.

Pure slug generator used by OrganizationsLive.Index and OrganizationsLive.New for live preview as the user types the org name. Reservation and uniqueness checks live in validate_slug/2 and the changeset — this function never touches the database.

generate_slug(name)

@spec generate_slug(String.t() | nil) :: String.t() | nil

Generates a slug from a name string.

Downcases, replaces non-alphanumeric runs with hyphens, trims hyphens. Does NOT validate the result -- call validate_slug/2 on the changeset after setting the generated slug.

validate_slug(changeset, config)

@spec validate_slug(Ecto.Changeset.t(), map()) :: Ecto.Changeset.t()

Validates the :slug field on a changeset.

Config keys used:

reserved_slugs (default: ~25 hardcoded words)
additional_reserved_slugs (default: [])
slug_format (default: ^[a-z][a-z0-9-]*[a-z0-9]$)
slug_length (default: {3, 63})
