What I do now is open project.clj, add dependency there, run lein deps restart repl, then use, require and so on.
The thing is that I don't really like to restart repl because the startup time is slow and I have to reload my files again.
So is there a better way to add dependency to lein project? without restarting the repl?
回答1:
You can use Alembic, a dynamic classpath loader and dependencies resolver. The good thing is that it doesn't load all pomegranate dependencies.
Add the following to your .lein/profiles.clj:
{:user
{:dependencies [[alembic "0.3.2"]]}}
Then in your Repl just load the classpaths you need, they will be pulled from the repositories by leinif need:
(require 'alembic.still)
(alembic.still/distill '[enlive "1.1.5"])
(require 'net.cgrand.enlive-html) should now work.
回答2:
for quick testing you can use pomegranate to add dependencies on the fly
=> (use '[cemerick.pomegranate :only (add-dependencies)])
nil
=> (add-dependencies :coordinates '[[incanter "1.2.3"]])
for actually adding a dependency I ususally hit
- Alt-x nrepl-restart
- ctrl-cctrl-k to reload the file,
- ctrl-calt-n to get back to the namespace i in the buffer
The whole process takes the jvm startup time (which i agree is a touch painful) plus five seconds. It helps to keep your project in a state where loading a file does all the require initialization.
