If you are using a mode whose indentation is provided by SMIE, you can
customize the indentation to suit your preferences. You can do this
on a per-mode basis (using the option smie-config), or a
per-file basis (using the function smie-config-local in a
file-local variable specification).
This option lets you customize indentation on a per-mode basis.
It is an alist with elements of the form (mode . rules).
For the precise form of rules, see the variable’s documentation; but
you may find it easier to use the command smie-config-guess.
This command tries to work out appropriate settings to produce your preferred style of indentation. Simply call the command while visiting a file that is indented with your style.
Call this command after using smie-config-guess, to save your
settings for future sessions.
This command displays the rules that are used to indent the current line.
This command adds a local rule to adjust the indentation of the current line.
This function adds rules as indentation rules for the current buffer.
These add to any mode-specific rules defined by the smie-config option.
To specify custom indentation rules for a specific file, add an entry
to the file’s local variables of the form:
eval: (smie-config-local '(rules)).
