A list of transformer functions that operate on flat parse tables.

Vector of file extensions indicating which file types should be styled. Case is ignored, and the . is optional, e.g. c(".R", ".Rmd"), or c("r", "rmd"). Supported values (after standardization) are: "r", "rprofile", "rmd", "rnw".

Character vector with paths to files that should be excluded from styling.

Character vector with directories to exclude (recursively). Note that the default values were set for consistency with style_dir() and as these directories are anyways not styled.

Whether or not to style code in roxygen examples.

Integer scalar indicating by how many spaces the whole output text should be indented. Note that this is not the same as splitting by line and add a base_indention spaces before the code in the case multi-line strings are present. See 'Examples'.

To indicate whether styler should run in dry mode, i.e. refrain from writing back to files ."on" and "fail" both don't write back, the latter returns an error if the input code is not identical to the result of styling. "off", the default, writes back if the input and output of styling are not identical.
