Pass a function (or, for withFieldLabel, a character vector) to
register it; pass NULL explicitly to clear that slot; omit the
argument to leave it untouched. Call with no arguments to inspect.
register_scenario_format(build, parse, withFieldLabel)Function (custom path builder), or NULL to clear.
Function (custom path parser), or NULL to clear.
Either:
a character vector of field names (e.g. c(".rep", ".SSP"))
– those fields' path segments get prefixed with the field name
itself (.rep5, .SSP370); or
a named character vector mapping field name to display label
(e.g. c(.rep = "rep", .SSP = "_ssp")) – those fields' path
segments get prefixed with the mapped label (rep5, _ssp370).
Pass character(0) or NULL to clear.
Invisibly, the current (build, parse, withFieldLabel) triple.
Lookup precedence (highest first): registered slot ->
pathBuild/pathParse defined in the global environment -> the
package defaults.
Override signature contract:
build(..., pre = "outputs") — receives the scenario as named
... args (one per field) plus pre; returns a path string.
parse(path, pre = "outputs") — returns a named list of fields.
