==== Limitations ====
By default, inferior-shell uses xcvb-driver:run-program/
as its universal execution backend, and has its limitations,
which are as follows.
Platforms supported inferior-shell at this time include:
ABCL, Allegro, CLISP, ClozureCL, CMUCL, ECL, LispWorks, RMCL, SBCL, SCL, XCL.
Platforms NOT supported (yet) include:
CormanLisp (untested), GCL (untested), Genera (unimplemented), MKCL (untested).
On supported platforms, inferior-shell works on both Unix and Windows.
One current limitation is lack of support for arbitrary input redirection.
The only possible input redirection is from /dev/null
or by inheriting the parent's standard input
when running in :interactive mode.
Last but not least, inferior-shell only supports
synchronous execution of sub-processes.
For asynchronous execution, please use IOlib or executor.
IOlib requires C compilation and linking, and may or may not support Windows.
executor only supports select implementations.
