I have something really weird going on with lein: when I run lein figwheel, compile seems to work fine, it loads up to

Prompt will show when Figwheel connects to your application
[Rebel readline] Type :repl/help for online help info

figwheel seems to compile old sources, not new ones. I have no idea why or where lein takes these sources from

How can I find out what's wrong (why lein is taking old sources over and over again)

@kurt-o-sys I have resolved that kind of situation by clearing the browser cache, although I am unsure of the underlying cause (unless it's just too many browser tabs)

did that also, will tray again 😛

when lein isn't running, I get an error in the browser (as expected). well, I'll try again 😛

hey guys, does lein offer a way to execute code inside the project.clj? i’m really just trying to use it to read env variables defined in an upstream process

@lwhorton you can use the ~ inside of the defproject

and you can also evaluate things at the top of the project.clj before the defproject

I’ve also seen people use read-eval literals in defproject It works and I do not know that I see a major difference between that and ~. However, there is a comment I’ve found in Leiningen core functions under defproject that says the next major version, 3, of lein will drop support for ~ in favor of using Clojure’s read-eval syntax instead

e.g.

(defproject mine/proj #=(find-my-version) 
 )

The ~ (unquote) style can be seen in the sample project https://github.com/technomancy/leiningen/blob/stable/sample.project.clj#L12 It is used in several places in this

The 3.0 deprecation of unquote is mentioned here https://github.com/technomancy/leiningen/wiki/ThreePointZero#custom-unquote
