codeq

Section titled “codeq”

codeq (‘co-deck’) is Clojure+Datomic application designed to do code-aware imports of your git repos into a Datomic db

Usage

Section titled “Usage”

Clone the codeq repo. Then (in it) run:

lein uberjar

Get Datomic Free

Unzip it, then start the Datomic Free transactor. Follow the instructions for running the transactor with the free storage protocol

cd theGitRepoYouWantToImport


java -server -Xmx1g -jar whereverYouPutCodeq/target/codeq-0.1.0-SNAPSHOT-standalone.jar datomic:free://localhost:4334/git

This will create a db called git (you can call it whatever you like) and import the commits from the local view of the repo. You should see output like:

Importing repo: git@github.com:clojure/clojure.git as: clojure
Adding repo git@github.com:clojure/clojure.git
Importing commit: e54a1ff1ac0d02560e80aad460e77ac353efad49
Importing commit: 894a0c81075b8f4b64b7f890ab0c8522a7a9986a

Analyzing...
Running analyzer: :clj on [.clj]
analyzing file: 17592186045504
analyzing file: 17592186045496
Analysis complete!

The import is not too peppy, since it shells to git relentlessly, but it imports e.g. Clojure’s entire commit history in about 10 minutes, plus analysis.

You can import more than one repo into the same db. You can re-import later after some more commits and they will be incrementally added.

You can then (or during) connect to the same db URI with a peer. Or, just start the Datomic REST service and poke around:

cd whereverYouPutDatomicFree
bin/rest -p 8080 free datomic:free://localhost:4334/

Browse to localhost:8080/data/. You should see the free storage and the git db within it.

The schema diagram will help you get oriented.
