Code foldingλ︎

Code folding allows you to collapse a code block onto one line, allowing you to see more of your code in the window. A code block for Clojure includes comments, def, defn and the threading macros -> and -->.

Overview of a namespace

z m shows just the names of all function definitions and vars in a namespace, providing a quick way to review all namespace api.


Evil state Description
z a Toggle fold for current code block
z c Folds a code block
z m Folds all code in buffer
z o Opens current folded code block
z O Opens current folded code block recursively
z r Opens all folded code blocks in the buffer

Code Fold Transient Stateλ︎

Space z opens a transient state for folding code, most useful when reviewing code.

Code folding methodsλ︎

There are two code folding methods, evil folding (the default) and origami. Evil fold is recommended for Clojure development.

Origami adds a recursive open and close and what it calls an org-mode header collapse (didn't seem to work on Clojure code). Origami seems less useful for Clojure than evil-fold, as folding seems to only work at the top level.

Origami allows you to write your own parser to teach different ways to fold code. Origami is a great choice if you want to customise your code folding.
