provide read-po-str to parse from a string

[omar-polo]

Hi,

I'm proposing the following patch to allow parsing the po file from a given string. I need this because I'm using shadow-cljs slurp-resource to inline parsed po files in a clojurescript application.

slurp-resources returns the content of the resources (equivalent to (-> "res-path" io/resource slurp)), in a way that shadow-cljs can recompile the bundle if that resource changes. To inline the parsed po file as clojure map in the clojurescript files I'm doing something like this:

;; clojure
(ns <app>.tr
  (:require [shadow.resource :as res]
            [pottery.po :as po]))

(defmacro inline-po [fname]
  (po/read-po-str (res/slurp-resource &env fname)))


;; clojurescript
(ns <app>.frontend.tr
  (:require-macros [<app>.tr :refer [inline-po]]))

(def DICT
  {:en (inline-po "gettext/en.po")
   :it (inline-po "gettext/it.po")})

I'm testing this (with a small pot) and it seems to work.

Cheers!

P.S.: the alternative would be to make ->kv public, but I like this approach better.

Hi @omar-polo, thanks for the PR! The approach is great. A nice solution to get recompilation going with Shadow, I'll add your example to the README and follow up with a clojars release.

Version 0.0.3 has been released with the changes. Note I've added read-po-str to the public interface of pottery.core so you don't have to include pottery.po anymore should this change in future releases.

Awesome, thanks!
