Standard library commands

(Commands which have operator syntax are omitted; see Operators for a full list.)

app {bundle_identifier as string} returning value

format_code {value as anything} returning string

lowercase {text as string} returning string

uppercase {text as string} returning string

write {value as anything}

(app is currently used by aelib but will go away once global @Apps namespace is implemented; write is currently limited to stdout, c.f. Swift print)

Example of use (using “pipe” syntax):

✎ "Bob"; uppercase; format_code; write
“““BOB”””
☺︎ nothing

Tip: Use pp/spp to inspect the previous line as a value (a group of expressions):

✎ pp
((write (format_code (uppercase “Bob”))))
