EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.
Note: This library is available via Quicklisp.
Here are some of the differences:
START (async) and RUN (sync) into two separate functions, rather than using a single function with a WAIT parameter that changes the function's specification;REPLACE-ENVIRONMENT-P parameter that indicates whether provided env vars should build on or replace the current environment.Read the API documention for details. It’s a bit spartan, but should explain a lot.
Not all functionality is available on all platforms. EXTERNAL-PROGRAM provides warnings and errors when these limitations are encountered. But I'll try my best to work around them.
There is currently at least some support for:
In addition to some implementations only providing blocking calls, some don’t use $PATH – the ones that don’t won’t find bareword commands, you’ll need to use a pathname.
