This library provides middleware/interceptorware to replace a response containing emoji names with bundled emoji images.
Add to your project.clj:
[emoji "0.1.0"]
The below usages are taken from the full pedestal service and compojure app examples in examples.
To use as an interceptor for a pedestal service:
(require '[io.pedestal.service.interceptor :refer [defon-response]])
(require '[emoji.core :refer [emoji-response]])
(defon-response emoji-interceptor
[response]
(emoji-response response))
;; add emoji-interceptor to a route
["/" {:get some-endpoint ^:interceptors [emoji-interceptor]]With emoji in place, a response body such as This page is on :fire:
becomes This page is on <img height='20' src='/images/emoji/fire.png' style='vertical-align:middle' width='20' />.
To use as middleware for a ring app:
(require '[emoji.core :refer [emoji-response]])
(require '[ring.middleware.resource :refer [wrap-resource]])
;; Assuming a compojure routes table called app-routes
;; resource middleware is needed to serve up bundled emojis
(-> app-routes
wrap-emoji
(wrap-resource "/public"))Options emoji-response and wrap-emoji can take:
- :wild - Converts every word that is a valid emoji name, no colon-delimitation necessary. For example "This page is on fire" would yield two emojis since on and fire are emoji names.
- :replace-fn - Customize the replacement text for an emoji. Useful for customizing the emoji image tag.
- :images-dir - Specify a local directory for emoji images.
To copy the bundled emojis: lein trampoline run -m emoji.core [DIRECTORY]
Please report them on github.
- This project would not be possible without @github providing their emojis.
