Alerts

A tiny library in Respo for showing alerts.

Usage

Clojars Project

[respo/alerts "0.5.1-a1"]

Hooks usages

[respo-alerts.core :refer [use-alert use-prompt use-confirm]]

use-alert

{:trigger (comp-buttom "trigger"),
 :text "message text",
 :style {}
 :card-style {}}
(let [alert-plugin (use-alert (>> states :alert) {:title "demo"})]
 (button
  {:on-click (fn [e d!] ((:show alert-plugin) d!))}))

use-confirm

{:trigger (comp-button "trigger"),
 :text "message text"
 :style {}
 :card-style {}}
(let [confirm-plugin (use-confirm (>> states :alert) {:title "demo"})]
 (button
  {:on-click (fn [e d!] ((:show confirm-plugin) d! (fn [] (println "after confirmed"))))}))

use-prompt

{:trigger (comp-button "trigger"),
 :text "message text",
 :style {}
 :input-style {}
 :card-style {}
 :multiline? false
 :initial "default text"
 :placeholder "input"
 :button-text "Submit"
 :validator (fn [x] (if (string/blank? x) "Blank failed" nil))}
(let [prompt-plugin (use-prompt (>> states :prompt) {:title "demo"})]
  (button {:on-click (fn [e d!]
            ((:show prompt-plugin) d! (fn [text] (println "read from prompt" (pr-str text)))))})
  (:ui prompt-plugin))

use-modal

(let [demo-modal (use-modal
                   (>> states :modal)
                   {:title "demo",
                    :style {:width 400},
                    :container-style {},
                    :render (fn [on-close] (div {} (<> "Place for child content")))})])
((:show demo-modal) d!)

use-modal-menu

(let [demo-modal-menu (use-modal-menu
                        (>> states :modal-menu)
                        {:title "Demo",
                         :style {:width 300},
                         :items [{:value "a", :display "A"}
                                 {:value "b", :display (div {} (<> "B"))}],
                         :on-result (fn [result d!] (println "got result" result))})])

((:show demo-modal-menu) d!)

Components

This library provides several UI components, so you need to control their visibilities with your own states, for example: {:show-alert? true}.

[respo-alerts.core :refer [comp-alert comp-prompt comp-confirm]]

Since every component has its own internal states, I use >> in all examples:

comp-alert is like alert("message") but with a callback function:

(comp-alert (>> states :alerts)
          {:trigger (comp-buttom "trigger"),
           :text "message text",
           :style {}
           :card-style {}}
           (fn [e dispatch!]
               (dispatch! :some/action "data")))

comp-alert is like confirm("message") but with a callback function returning result:

(comp-confirm (>> states :confirm)
          {:trigger (comp-button "trigger"),
           :text "message text"
           :style {}
           :card-style {}}
          (fn [e dispatch!]
              (dispatch! :some/action "data")
              (println "confirmed!")))

comp-prompt is like prompt("message", "default") but with a callback function returning result:

(comp-prompt (>> states :prompt)
          {:trigger (comp-button "trigger"),
           :text "message text",
           :style {}
           :input-style {}
           :card-style {}
           :multiline? false
           :initial "default text"
           :placeholder "input"
           :button-text "Submit"
           :validator (fn [x] (if (string/blank? x) "Blank failed" nil))
           :card-style {}}
          (fn [result dispatch! mutate!]
              (dispatch! :some/action "data")
              (dispatch! cursor (assoc state :show-prompt? false))
              (println "finish editing!" result)))

comp-select pops up a select menu and returns a result in callback function:

(def candidates [{:value "haskell", :display "Haskell"}
                 {:value "clojure", :display "Clojure"}
                 {:value "elixir", :display "Elixir"}])

(comp-select (>> states :select) (:selected state) candidates
          {:style-trigger {},
           :text "Select a item from:"}
          (fn [result d!]
              (println "finish selecting!" result)
              (d! cursor (assoc state :selected result))))

comp-modal for rendering modal without child:

(let [on-close (fn [d!] (d! cursor (assoc state :show? false)))]
 (comp-modal
  {:title "Demo", :style {:width 400}, :container-style {}
   :render (fn [on-close] (div {} (<> "Place for child content")))}
  show?
  on-close))
(comp-modal-menu
  (:show-modal-menu? state)
  {:title "Demo", :style {:width 300}}
  [{:value "a", :display "A"} {:value "b", :display (div {} (<> "B"))}]
  (fn [d!] (d! cursor (assoc state :show-modal-menu? false)))
  (fn [result d!]
    (println "result" result)
    (d! cursor (assoc state :show-modal-menu? false)))))
