"Predefined formatting styles for ESS code.
|
|
Use `ess-set-style' to apply a style in all R buffers. The values of
|
|
all styles except OWN are fixed. To change the value of variables
|
|
in the OWN group, customize the variable `ess-own-style-list'.
|
|
DEFAULT style picks default (aka global) values from ESS
|
|
indentation variables. In addition, ESS provides many indentation
|
|
styles, the most important being the RRR and the RStudio
|
|
variants.
|
|
|
|
RRR is the common R style that adheres closely to R internal
|
|
standards. RRR+ is the same except it also aligns blocks in
|
|
function calls with the opening delimiter, producing more
|
|
indentation. The C++ style (named like this for historical
|
|
reasons rather than any resemblance to existing C++ indentation
|
|
schemes) is halfway between these two styles and indent block
|
|
arguments from the start of the surrounding function's name.
|
|
|
|
The RStudio style closely mimics the indentation of the RStudio
|
|
editor. RStudio- is the same except it does not align arguments
|
|
in function calls, which corresponds to the settings of some
|
|
RStudio users.
|
|
|
|
ESS indentation is fully specified by the following offsets and
|
|
variables. See the documentation of these variables for examples.
|
|
|
|
Offsets:
|
|
|
|
- `ess-indent-offset': main offset inherited by other settings
|
|
|
|
- `ess-offset-arguments': offset type for function and bracket
|
|
arguments
|
|
|
|
- `ess-offset-arguments-newline': offset type of arguments
|
|
when ( or [ is followed by a new line.
|
|
|
|
- `ess-offset-block': offset type for brace and anonymous
|
|
parenthesis blocks
|
|
|
|
- `ess-offset-continued': offset type for continuation lines in
|
|
multiline statements
|
|
|
|
|
|
Overrides (implies vertical alignment):
|
|
|
|
- `ess-align-nested-calls': functions whose nested calls
|
|
should be aligned.
|
|
|
|
- `ess-align-arguments-in-calls': calls where
|
|
`ess-offset-arguments' should be ignored
|
|
|
|
- `ess-align-continuations-in-calls': whether to ignore
|
|
`ess-offset-continued' in calls.
|
|
|
|
- `ess-align-blocks': whether to ignore `ess-offset-blocks' for
|
|
function declarations or control flow statements.
|
|
|
|
|
|
Control variables:
|
|
|
|
- `ess-indent-from-lhs': whether to indent arguments from
|
|
left-hand side of an assignment or parameter declaration.
|
|
|
|
- `ess-indent-from-chain-start': whether to indent arguments from
|
|
the first of several consecutive calls.
|
|
|
|
- `ess-indent-with-fancy-comments': whether to indent #, ## and
|
|
### comments distinctly.")
