Clojure Write

How to Evaluate Code

Bottom-up Dev Loop

1. Write code into a file.
2. Evaluate the file's namespace and make sure it loads correctly with:

./bin/mage -repl --namespace metabase.app-db.connection

3. Call functions in the namespace with test inputs, and observe that the outputs are correct Feel free to copy these REPL session trials into actual test cases using deftest and is.
4. Once you know these functions are good, return to 1, and compose them into the task that you need to build.

Critical Rules for Editing

• Be careful with parentheses counts when editing Clojure code
• After EVERY change to Clojure code, verify readability with -check-readable
• End all files with a newline
• When editing tabular code, where the columns line up, try to keep them aligned
• Spaces on a line with nothing after it is not allowed
