Accepts a raw pipeline command line (with or without the gdal [vector|raster] pipeline prefix) and parses it into an ordered list of steps, resolving nested pipelines ([ ... ]) and associating arguments with their values using the GDAL contract to disambiguate boolean flags.

Usage

parse_pipeline(x, contract = gdalviz_contract())

Arguments

x

A pipeline command-line string.

contract

A gdalviz_contract used to disambiguate argument types.

Value

A gdalviz_pipeline object.
