on reloading a transpile-to-Clojure language about boot-reload HOT 11 CLOSED

@jiyinyiyong you can make a cirru task that compiles your files to .cljs and those will be picked up by the cljs task and later in the pipeline by the reload task. Definitely sounds doable. I suggest asking in the Slack channel if you're looking for further advice on how to implement this.

from boot-reload.

Martin is right. All you need to do is write a task to do your compile.
When you compose your external task, the order of your sub-tasks will be
something like serve, watch, speak, reload, custom, cljs. (I'm assuming
boot-jetty here. For boot-http, I think serve goes at the end.)

@jiyinyiyong compiling to ClojureScript is awesome! Boot was originally motivated to make exactly this easy. https://github.com/hoplon/boot-hoplon might be a useful reference. It's the task for http://hoplon.io that compiles .cljs.hl into .cljs files and is compatible with all other boot-cljs tooling.

@alandipert sounds good. Have you used that with boot-reload yet, does it work well?

@martinklepsch I will ask in Slack next morning. Actually these lines of code made me worried. I tried to look into fileset emitted from watch, and it seemed to be a full list of files, and in boot-reload it compares all the files in order to find changes, which means I have to compile all my files. That is unlike incremental compiling:
https://github.com/adzerk-oss/boot-reload/blob/master/src/adzerk/boot_reload.clj#L18-L24

(defn- changed [before after static-files]
  (when before
    (->> (fileset-diff before after :hash)
         output-files
         (sort-by :dependency-order)
         (map tmp-path)
         (remove static-files))))

I'll try to dig deeper...

I believe this is the cost of easy composition. All the sub-steps are fully
decoupled. Efficiency in the form of incremental compilation goes out the
window. Your cljs converter shouldn't even need to know that it is being
invoked multiple times.

It is the KISS approach that can accomplish a great deal in a
straight-forward way. Without much in the way of preconceptions about what
needs to be done, which is what you often need but rarely get from a build
tool. And while it may seem inefficient, remember that the most valuable
resource is qualified developers and that such an approach lends itself to
use within a cluster. :D

Iron being really cheap these days.

In my estimation, boot is pure genius. You just need to think cloud.

@laforge49 I came from JavaScript community and Webpack already did a very good job on such cases. I mean files are compiled incrementally in develop mode. I believe there's a solution for Clojure too, but with the help of boot-reload supporting it.

I find myself repeatedly in awe of the clojure community at large.

@jiyinyiyong boot-cljs handles incremental compilation of cljs sources. And similarly you can implement your cirru compiler to do some sort of incremental compilation. boot-reload solely provides a mechanism to reload files in a browser, it has nothing to do with compilation, you can use it for CLJS and CSS and other types of files

Thanks. I finished the plugin days back. Closing.

(deftask dev []
  (set-env!
    :source-paths #{"cirru/src"})
  (comp
    (html-file :data {:build? false})
    (watch)
    (transform-cirru)
    (reload :on-jsload 'boot-workflow.core/on-jsload)
    (cljs)
    (target)))
