Inform the Protocol clj-frontend. #155

Open felipecc opened 9 years ago

Hello everybody,

How can I tell clj-frontend protocol. My goal is within my workflow execute commands to be my clojures functions. I'm sorry for bad English.

Thanks in advance

Sorry, I don't really understand what you're asking. clj-frontend isn't a protocol for defining what your steps do within a drakefile; it is an alternative mechanism for programmatically constructing a workflow instead of using a drakefile. @dirtyvagabond, it sounds like this might be about how to make a step run clojure code, and I'm not quite sure how this is supposed to be done. I see c4-rows, which lets you apply a clojure function on each row of an input, but I can't find something that just runs a clojure function against the input as a whole (eg, by passing it a Reader). Does such a thing exist? If so, that may be what @felipecc is looking for but as I said I'm not sure.

Thanks for answering. Reading about the clj-frontend in the examples noted that only bash commands were executed, I think not expressed myself in the right way and I apologize, really like inside the frontend clj-in commands like to be able to use clojures functions, it would be possible ? The C4 is interesting, but did not see a way to call some functions already created earlier, if there is a way to do this solves my issue. I believe clojure is very able to do within steps of transformations. Thank you, and sorry for my bad English.
