Clojure Text Objects and Indentation

Text Objects (textobjects.scm)

Match in/around selections for Clojure code:

f (function)

• Inside: (defn foo [x] |body|) - body only
• Around: |(defn foo [x] body)| - entire form

e (class/data structure)

• Inside: (defrecord Point [x y] |methods|) - body after name
• Around: |(defrecord Point [x y] methods)| - entire form

T (test)

• Inside: (deftest my-test |(is (= 1 1))|) - test body
• Around: |(deftest my-test (is (= 1 1)))| - entire form

a (parameter)

• Inside: [|x y z|] - parameters only
• Around: |[x y z]| - includes brackets

entry

• Inside/Around: (foo |bar| baz) - same, selects individual element

c (comment)

• Inside: |; single comment| - one comment
• Around: |; comment 1\n; comment 2| - consecutive comments (matches upward from cursor)

Indentation (indents.scm)

Indentation rules for Clojure code:

1. Two-element alignment: When a list has two elements on the first line (excluding literals and special forms), align subsequent lines to the second element
2. Nested list alignment: When the first element is a list on its own line, align the outer list to it
3. Single-element indent: When the first element is on its own line (not a literal or special form), indent the body by one level
4. Literal alignment: When the first element is a literal (true, false, nil, string, number, keyword), align to it
5. Special forms: def*, let*, binding, loop, for, doseq, when-*, if-*, with-*, fn, and ns forms indent their body by one level
6. Vector/map alignment: When first two elements are on the same line (common in let bindings), align subsequent pairs to them
7. Collection indent: Vectors, maps, and sets are indented by one level
