# CHAMELEON
Feeds the Gallifrey time database with entity events
### Building the project
1. mvn clean install
2. mvn package
### Generating a code coverage report
1. mvn clean install
2. mvn exec:java -Dexec.classpathScope=test -Dexec.mainClass='clojure.main' -Dexec.args="--main cloverage.coverage -n 'chameleon.*' -t 'chameleon.testing'"
2.1. Follow the instructions to view the report.
3. To tweak the report generation, follow the instrustions here:
https://github.com/cloverage/cloverage
### Developing
1. I use Leiningen for building my clojure project and for dependency
management. You can read about Leiningen and follow the tutorial at
the link:
https://github.com/technomancy/leiningen
2. If you make ** changes to the project.clj file, you are required to
re-generate the pom.xml by running `lein pom`** (requires leiningen
to be instaled).
You can also add your changes to the pom.xml file manually.
3. I use Emacs as my editor and CIDER for interactive development in
Clojure.
- CIDER: https://github.com/clojure-emacs/cider
- Emacs: https://www.gnu.org/software/emacs/
- Here is a tutorial on Emacs: https://www.gnu.org/software/emacs/tour/
- Here is the emacs configuration I've used, it includes the CIDER
package:
https://github.com/sandhu/emacs.d
4. Start nrepl `C-c M-j` (you have to be in any *.clj file in the
chameleon project). If the cider-repl buffer doesn't open
automatically, use `C-x b` and use the arrow keys to find the
`cider-repl chameleon` buffer and press enter.
5. Open the dev.clj file by `C-x C-f`, load it `C-c C-k` and switch
your namespace to dev `C-c M-n`.
6. In the repl buffer you should see that the namespace went from `user`
to `dev`.
7. Make sure the configuration is correct in the dev.clj file and once
verified, in the repl buffer type `(go)` and press enter.
8. You can verify everything is running by generating/adding an event
to dmaap and seeing it flow through chameleon in the error.log file.
### Running it locally (Assuming you're not using Emacs and using
`lein repl` from the command line)
**Make you're in the directory at the root of your project. Open the
file `chameleon/dev.clj` and update the config to the correct
dmaap host, topic, and make sure you're using the correct
consumer group and id.**
1. On the command line, execute `lein repl`
2. Once in the clojure repl, load the dev namespace
(load "dev")
3. Go into the dev namespace
(in-ns 'dev)
4. Run the following command in the repl
(go)
