new task: run about leiningen

[ericlavigne]

I created a plugin for this issue:

 http://github.com/ericlavigne/leiningen-run

Also it would be nice if you wouldn't need MainClass for it but just run Clojure script.

[ericlavigne]

I can find MainClass in project.clj. How would I determine which file to use as the script?

One way is to pass it as a commandline argument

• lein run main.clj

However, I would also like to be able to provide arguments to -main

• lein run 8080 true

which makes this ambiguous

• lein run main.clj 8080 true

[ericlavigne]

Is it worth adding a "script" task that is identical to "run" except that it expects a script name?

• lein run 8080 true
• lein script main 8080 true

[neotyk]

How about adding :script to project.clj so you don't have to change optional parameters syntax?

[ericlavigne]

If the project only has one :script, then it seems the only advantage of script vs main class is to avoid "(:gen-class)" and "(defn main []", which will still be needed if you want to create an executable jar for this application.

Though I am not convinced that you must have a script, script functionality could mimic Leiningen's behaviour in how it uses project.clj.

lein run could run main.clj by convention (run.clj might be a better name because it matches the name of the Leiningen task) if it exists. Any other scripts or behaviour could be dispatched from that script. This script wouldn't be run by a executable jar but could be useful for porting legacy Clojure scripts to Leiningen, and non-slime users who run a new repl every time they save their code (they do exist).

I haven't tried lein run yet. If my opinion changes I will feedback here.

Closing this issue here; will merge into leiningen proper after the run plugin has seen more use. Thanks!
