Did you further think about your previous suggestion to provide the functionality of "calling" a qualified function from the command line of clojure.main?
I'd like to see a (:main...) clause supported by ns to name the "main" entry point for a namespace. In the absence of that, "main" itself is a decent substitute.
I'd still like to suggest a '-E' flag, which basically specifies the entry point to call. So one could do clojure.main -E some.namespace/some-func
I like that. Perhaps we could even leave out the "-E" resolving the namespace/filepath ambiguity by trying the namespace first and if it's not found, trying the filepath.
This would require some.namespace to be on the classpath. clojure.main some/file.clj would just execute some/file.clj as a script.
clojure.main does this one now.
clojure.main -E some.namespace/some-func some/namespace.clj
I like this too.
would first read some/namespace.clj and then execute some.namespace/some-func. This would not require some.namespace to be on the classpath, because it could be defined in the given file.
Right. very flexible.
This would allow to make the loading of script files side-effect free, which would ease their use during debugging. And it would allow different entry points in a single script.
Nice benefit.I like these changes. More discussion, especially from everyone interested in more flexible launching of Clojure via clojure.main would give us an indication of how important a change it is.
