Evaluating Clojure

Practicalli recommends evaluating Clojure expressions in the source code buffer, which displays the results next to the expression until you move the cursor.

, e f evaluates the top-level expression at cursor.

, e p f evaluates the top-level expression at cursor and pretty prints the result in a separate buffer. Useful for results that are collections and nested collections. Use the cider inspector for large data sets.

, e ++semi-colon++ evaluates the top-level expression at cursor and add the result as a comment. Useful for a design journal and when exploring a code base.

Review the evaluating expressions page for more examples and a deeper explanation.

Pretty Print results

Pretty Print displays evaluation results in an expanded structure which is more human readable.

, e p e displays the evaluation result from evaluating the last s-expression in a separate popup buffer window

, e p f is the same, but for the top level expression

, e p ++semi-colon++ and , e p ++semi-colon++ pretty print results as a comment under the evaluated form.

Displaying large results

, e p f or , e p e pretty prints the results into a new buffer. This is excellent for evaluating expressions that return a large result, eg. a large map. Keep the Cider Inspector buffer open to see the results of further evaluation commands, until the inspector buffer is closed.

, d v the cider-inspector is a great way to navigate through a large data structure, especially if it is nested.

Quick reference

, e menu provides many different ways of evaluating parts of an expression, or a complete expression.
