Start Portal and capture all evaluation results over nrepl when portal middleware included in the REPL startup.

All evaluation carried out over nREPL, i.e. between the connected editor and the Clojure REPL, will be sent to Portal.

Use Practicalli Clojure CLI Config aliases or define your own alias in the project or user deps.edn file.

:repl/reloaded aliases from Practicalli Clojure CLI Config starts a REPL process with Portal and nrepl middleware

Connect an editor to the REPL via the nREPL server port created during the REPL startup

clojure -M:repl/reloaded

make repl also launches Portal listening over nREPL in projects created with Practicalli Project Templates

Define an alias that includes the portal library in the :extra-deps section and portal.nrepl/wrap-portal nrepl middleware in the :main-opts section with the --middleware flag.

Launching Portalλ︎

Start Portal listening to all evaluations

(ns portal
   [portal.api :as inspect]))

(def instance
  "Open portal window if no portal sessions have been created.
   A portal session is created when opening a portal window"
  (or (seq (inspect/sessions))
      (inspect/open {:portal.colors/theme :portal.colors/gruvbox})))

;; Add portal as tapsource (add to clojure.core/tapset)
(add-tap #'portal.api/submit)


A portal theme can be specified when starting portal, e.g. :portal.colors/gruvbox.
