Use board that for a website that uses the data.txt
data.txt file is a YAML that provides some basic metadata
about a directory of files.
legacy_datatxt( url, headers = NULL, cache = board_cache_path(name), needs_index = TRUE, browse_url = url, index_updated = NULL, index_randomize = FALSE, path = NULL, versions = FALSE, name = NULL, ... ) board_register_datatxt( url, name = NULL, headers = NULL, cache = board_cache_path(name), ... )
Path to the
data.txt file or directory containing it.
Optional list of headers to include or a function to generate them.
Cache path. Every board requires a local cache to avoid downloading files multiple times. The default stores in a standard cache location for your operating system, but you can override if needed.
Does this board have an index file?
Not currently used
Callback function used to update index
data.txt at a parameter with random
query string to defeat caching?
Should this board be registered with support for versions?
An optional name used identify the board. This is no longer generally needed since you should be passing around an explicit board object.
Additional parameters required to initialize a particular board.
