Render a pipeline as a canonical GDALG command line

Serializes a parsed parse_pipeline() result back into a single-line command_line string, using the same minimal quoting that GDAL itself uses when it writes *.gdalg.json files. The result round-trips: parsing the output again yields an equivalent pipeline.

Usage

render_command_line(x, prog = TRUE, type = NULL)

Arguments

x

A gdalviz_pipeline, or a string/path accepted by read_gdalg().

prog

Logical or NULL. Whether to emit the leading gdal <type> pipeline program prefix. Defaults to TRUE.

type

Pipeline type ("vector" or "raster"). Defaults to the type detected during parsing, falling back to "vector".

Value

A length-one character vector.
