Upgrading

0.12 from 0.11

Update the Duct dependencies in your project file:

[duct/module.cljs "0.4.1"]

Update the duct/lein-duct plugin version:

[duct/lein-duct "0.12.1"]

0.11 from 0.10

Update the Duct dependencies in your project file:

[duct/core "0.7.0"]
[duct/module.logging "0.4.0"]
[duct/module.web "0.7.0"]
[duct/module.ataraxy "0.3.0"]
[duct/module.cljs "0.4.0"]
[duct/module.sql "0.5.0"]

Update the duct/lein-duct plugin version:

[duct/lein-duct "0.11.2"]

Change the -main function in main.clj and replace the duct/prep and duct/exec steps with duct/exec-config. The exec-config key will need an additional profiles argument that should be set to [:duct.profile/prod].

Your -main function should look something like:

(defn -main [& args]
  (let [keys     (or (duct/parse-keys args) [:duct/daemon])
        profiles [:duct.profile/prod]]
    (-> (duct/resource "bar/config.edn")
        (duct/read-config)
        (duct/exec-config profiles keys))))

Between version 0.10 and 0.11 the way configuration files connect together has changed.

First, add these new profile keys to your config.edn file:

:duct.profile/base  {}
:duct.profile/dev   #duct/include "dev"
:duct.profile/local #duct/include "local"
:duct.profile/prod  {}

Then remove the following keys from all your configuration files, including dev.edn and local.edn:

  • :duct.core/include
  • :duct.core/environment

Finally, move all your non-module keys in config.edn into the :duct.profile/base key. Your configuration should look something like:

{:duct.profile/base
 {:duct.core/project-ns example
  ;; ... more non-module keys
  }

 :duct.profile/dev   #duct/include "dev"
 :duct.profile/local #duct/include "local"
 :duct.profile/prod  {}

 :duct.module/logging {}
 ;; ... more module keys
 }

If you have split your configuration up into multiple files, and have updated your :duct.core/include key, then you'll need to change this into #duct/include directives and profile keys that inherit from :duct/profile or :duct.profile/base if you want the profile to be included by default.

So for example, if you had a configuration with:

{:duct.core/include ["migrations"]}

Then you'd change it to:

{:duct.profile/migrations #duct/include "migrations"}

And in your src/duct_hierarchy.edn file, you'd add a derivation like:

{:duct.profile/migrations [:duct.profile/base]}

If you have any custom modules in your application, these will have to be changed as well. In 0.11, dependencies for modules are added with ig/prep-key, and the transformation function returned by ig/init-key.

So if you have something like this in 0.10:

(defmethod ig/init-key :foo.module/example [_ opts]
  {:req [:some.existing/key]
   :fn  (fn [config] ...)})

In 0.11 this would be changed to:

(defmethod ig/prep-key :foo.module/example [_ opts]
  (assoc opts ::requires (ig/ref :some.existing/module)))

(defmethod ig/init-key :foo.module/example [_ opts]
  (fn [config] ...))

Note that dependencies added by prep can only be between modules or profiles, so instead of depending on :duct/logger, for example, you might depend on :duct.module/logging.

You can also use ig/refset to make an optional dependency. If a module exists, ensure that your module comes after it - otherwise order as normal.

0.10 from 0.9

Update the Duct dependencies in your project file:

[duct/core "0.6.1"]
[duct/module.logging "0.3.0"]
[duct/module.web "0.6.0"]
[duct/module.ataraxy "0.2.0"]
[duct/module.cljs "0.3.0"]
[duct/module.sql "0.3.0"]

Update the duct/lein-duct plugin version:

[duct/lein-duct "0.10.0"]

Add the duct.core/load-hierarchy function to main.clj and dev.clj. This should be a top-level form placed just below the ns declaraton:

(duct/load-hierarchy)

Change the -main function in main.clj to include a prep step. It should look something like:

(defn -main [& args]
  (let [keys (or (duct/parse-keys args) [:duct/daemon])]
    (-> (duct/read-config (io/resource "foo/config.edn"))
        (duct/prep keys)
        (duct/exec keys))))

Add a require for duct.core.repl in dev.clj:

[duct.core.repl :as duct-repl]
