There are two cases of interest configured by this variable.
|
|||
|
|
|
|||
|
|
- Case (A) is when at least one function argument is on the same
|
|||
|
|
line as the function name.
|
|||
|
|
- Case (B) is the opposite (no arguments are on the same line as
|
|||
|
|
the function name). Note that the body of macros is not
|
|||
|
|
affected by this variable, it is always indented by
|
|||
|
|
`lisp-body-indent' (default 2) spaces.
|
|||
|
|
|
|||
|
|
Note that this variable configures the indentation of function
|
|||
|
|
forms (and function-like macros), it does not affect macros that
|
|||
|
|
already use special indentation rules.
|
|||
|
|
|
|||
|
|
The possible values for this variable are keywords indicating how
|
|||
|
|
to indent function forms.
|
|||
|
|
|
|||
|
|
`:always-align' - Follow the same rules as `lisp-mode'. All
|
|||
|
|
args are vertically aligned with the first arg in case (A),
|
|||
|
|
and vertically aligned with the function name in case (B).

case (B) is indented like a macro body.
