hey guys is there something in lein that will reload my app when there are changes? so i don't have to ctrl + c and restart?

Reload what in particular?

like i'm working on a server and running it on localhost for dev

and it would be nice if lein run would reload itself when changes were made

Oh there's a plugin for that. Give me a moment

cool, thanks

Look up lein reload and lein auto reload

nice, thank you

Although editors with repl functionality usually have the ability to reload a namespace

Vim-fireplace has Require! for example

Also, be aware that reloading on save may cause issues if you're not completely sure of what you're saving

Endless loops in code, for example

yeah that's a good point

If you're running an editor with repl integration, they usually have a motion to send the current form off, so full namespace reload is only usually needed when playing with protocols and other fun things

Anyways, hope that helped

thanks for all the advice, i'm gonna check out some of the plugins and see how bad it could possibly be

Oh, if you're running a ring server you'll want the reload middleware from that instead

i'm using compojure which i believe uses ring?

Reloading the namespace has issues due to when things are attached

you mean like sockets and stuff?

Errr ring.middleware.reload/wrap-reload

Nah, iirc when routes are declared the functions are compiled and attached

oh, attached in that sense

Reloading the namespace changes the functions, but not the ones attached to the routes

The reload middleware searches on request and recompiles the namespace accordingly

(And recompiles the routes)

hey folks, is there an easy way to swap the name of my jar and uberjar in lein?

say :jar-name foo-min-SNAPSHOT-1.1.jar and :uberjar-name foo-SNAPSHOT-1.1.jar?

assuming project name is foo

@markbastian yes, you can customize the jar & uberjar names. See https://github.com/technomancy/leiningen/blob/master/sample.project.clj#L400-L404

;; Including %s will splice the project version into the filename. :jar-name "sample.jar"

so, does this mean I can do "sample-%s.jar" for example?

are other project variables available, like in maven (e.g. http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-properties.html)?

it appears only :version is supported. Here’s the source code of that: https://github.com/technomancy/leiningen/blob/0edda36f63a3f714230fe93104f9eff7174ccba7/src/leiningen/jar.clj#L221-L222

actually, it looks like :version and :name are both being referenced. I wonder if there's a way to get the project in a repl and dump the map.

You can use the profile in the target directory name, so maybe that too?
