clj-repl-gui

Simple tools for visualising data at the repl using swing

Data-table

(data-table data {:keys [override-column-labels])

Returns a swing JTable containing the data, laid out as sensibly as possible. Handles lists, maps and beans, both homogeneous and heterogeneous.

• override-column-labels to override inferred column headings

Clicking on a cell in a data-table will show a new data-table for the data within the cell.

Watcher

(watcher reference {:keys [limit elide-duplicates?]
                     :or {limit 0 elide-duplicates? false)

Watches for changes to the reference, returns a data-table containing the history of changes.

• limit restricts the length of history kept, 0 means unlimited history
• elide-duplicates? will not record changes that maintain the same state as before

Show it on-screen

(show! component)

Pops up a small scrollable window containing the swing component passed in.

Example usage

; watching changes on an atom
(def x (atom [1]))
(show! (watcher x {:limit 10 :elide-duplicates? true}))
(swap! x conj 2)
(swap! x conj 3)


; showing various pieces of data
(show! (data-table [1 2 3]))

(show! (data-table [[1 "jon" :user]
                    [56 "dave" :admin]
                    [24 "roger" :user :optional-value]]
                    {:override-column-labels ["id" "name" "role" "other"]}))
                    
(show! (data-table [{:id 1 :name "jon" :role :user}
                    {:id 56 :name "dave" :role :admin}
                    {:id 24 :name "roger" :role :user :optional-key :optional-value}]))
                    
(show! (data-table {:a 1 :b 2 :c {:hello [1 2 3] :test "world" :other #{2 4}}))

(show! (data-table (new java.util.Date)))
