`(sigil browser local-storage)`

(sigil browser local-storage) - Browser localStorage facade.

None of these raise: the JavaScript side catches every exception the storage API can throw (a quota error, a sandboxed page with storage disabled, no localStorage at all) and reports it as #f, so a caller decides what a missing or unwritable value means. Under a non-browser build every procedure answers #f too.

Exports

local-storage-getprocedure

Read the string stored under KEY, or #f when there is none.

raises: never; a missing key, a blocked storage API and a non-browser target all answer #f.

(local-storage-get "save")  ; => "(board ...)" or #f

local-storage-set!procedure

Store VALUE (a string) under KEY. Returns #t when stored.

raises: never; #f means the write did not happen (quota, a blocked storage API, a non-browser target).

(local-storage-set! "save" "(board ...)")  ; => #t

local-storage-remove!procedure

Remove KEY. Returns #t when the storage API accepted the call, whether or not the key existed.

raises: never; #f means storage is unavailable.

(local-storage-remove! "save")  ; => #t
