File I/O Blocks

Blocks for reading and writing various file formats

Teach blockr.io a file format or a container – a location holding several tables – and build read expressions from what is registered.

register_format(): Register a file format
register_container(): Register a container
format_read_expr(): Read expression for a single file
container_read_expr(): Read expression for a container
container_kinds(): What containers are registered
container_list_tables() container_table_info(): Discover the tables in a container

An entry declares what it accepts, and blocks generate their settings fields from the answer.

opt_choice() opt_text() opt_number() opt_flag(): Declare a format's reader options
format_options(): The options a format declares
source_options(): The options a source offers
member_options(): The options a set of files understands
format_options_ui(): Fields for a set of declared options
format_options_values(): Read declared option fields back off the inputs
format_options_update(): Push option values back into declared option fields
