Description
Real world example:
https://github.com/gijzelaerr/spiel/blob/181b889c77a59a83f1939a2e2c08d8aea5e14469/steps/wsclean.cwl
The tool expects -size 2048 2048
and the POSIX shell sh
turns that into three entries in the argument array: -size
, 2048
, and 2048
. However this description passes the sizes in as a single string which becomes only two entries -size
and 2048 2048
which is rejected by the tool.
Ideally the tool would accept 2048 2048
(with the embedded space) or have split options for each element (like -xsize
and -ysize
)
Here's a workaround using arguments
that doesn't require any code changes to the underlying tool
