Factory Pattern

Function that encapsulates object creation, returning an allocated and initialized struct. Centralizes construction logic and hides allocation details from callers.

ikigai Application

Current usage:

• ik_scrollback_create()

  - creates scrollback buffer

• ik_mark_create()

  - creates checkpoint marks

• ik_input_parser_create()

  - creates input parser

Convention: Use

*_create()

for heap allocation (caller owns),

*_init()

for initializing pre-allocated memory.

With ik_env_t: Factories should receive

ik_env_t *env

as first parameter for access to logger, config, and clock during construction.

Testing: Factories enable injecting dependencies at creation time rather than reaching for globals.
