Structs

BrokenView

Dataset

What a view is matched against: where the dataset was read from, and which table of it. Standard input’s - is a path no path criterion fits, so data piped in or a frame handed over is matched by its columns alone.

MatchCriteria

SavedChart

A view’s chart: what is charted, and the options it is drawn with.

SavedChartExport

A chart export’s settings, as a view keeps them.

SavedSample

A view’s sample as a view keeps it: which rows, how they are picked, how many, and the seed that draws the same ones again.

SavedView

Every field but the settings may be left out, so an exported chart’s recipe, which carries only the settings, reads as a view.

ViewManager

ViewSettings

Views

The saved views, read on a worker from the moment run starts.

Enums

MatchReason

Why a view’s criteria fit the open file, in the words the list annotates rows with. The strongest reason wins: the same file beats the same columns beats a glob.

Functions

criteria_match

Whether the view’s own criteria match this file: a path or pattern hit, or every schema column the view asks for present. Distinct from the relevance score, which also carries usage and recency and so is never zero for a view that has been used — a ranking, not a claim of fit.

exact_location

A dataset’s location as a view records it: a URL as written, a local path made absolute and resolved. The save form offers this and matching compares with it, so the two are spelled alike.

exact_path_matches

Whether the view’s exact path names the dataset at file_path. A URL compares as text less any trailing slash, which is how a directory’s URL may or may not end, and with its scheme in either case, as datui opens it.

filename_pattern_matches

Whether the view’s filename pattern fits the name of file_path.

match_reason

The strongest criterion of the view’s that fits this file, or None when none does. This is the same test criteria_match gates on, kept in one place so the list’s “why it matches” annotation can never disagree with what V and auto-apply do.

path_pattern_matches

Whether the view’s path pattern fits file_path, as opened or as the save form spells it: a file opened by a relative path or through a link is still under the resolved directory its pattern was suggested from.

relative_location

A local dataset’s path relative to the working directory, when it is under it. A URL has none: it names the same data wherever datui runs.

relative_path_matches

Whether the view’s relative path names the dataset at file_path.
