Typedef Documentation

dt_style_scenario_result_t

typedef struct dt_style_scenario_result_t dt_style_scenario_result_t

One-line scenario result printed after every style has run.

The full diagnostics are emitted where the failure is detected. This summary keeps only the first failure reason so the final output stays readable when several fixtures are executed in a single run.

Variable Documentation

test_image_dir

char* test_image_dir = NULL

static

Run style-application scenarios from tests/styles.

Each *.dtstyle file defines one scenario. The basename of the style file is used to find start_<style>.xmp and end_<style>.xmp. The start sidecar is optional: if it is missing, the runner keeps the raw import history. The end sidecar is required and provides the expected history after applying the style.

The comparison is intentionally limited to the resulting pipe order and final enabled states. The history stack can legitimately differ after a merge, so the enabled-state check only looks at the last active history item for each module instance.
