styler

The goal of styler is to provide non-invasive pretty-printing of R source code while adhering to the tidyverse formatting rules. Support for custom style guides is planned.

You can install the package from GitHub:

# install.packages("remotes")
remotes::install_github("krlmlr/styler")

You can style a simple character vector of code with style_text():

ugly_code <- "a<-function( x){1+1}           "
style_text(ugly_code)
#> a <- function(x) {
#>   1 + 1
#> }

There are a few variants of style_text():

• style_file() styles .R and/or .Rmd files.
• style_dir() styles all .R files in a directory.
• style_pkg() styles the source files of an R package.
• RStudio Addins for styling the active file, styling the current package and styling the highlighted code region.
