How to config styler?

[kalaschnik]

I sometimes run into the case where I want to provide information about parameters. Yet, when using styler my function goes from this:

my_fun <- function(
    param1,
    param2,
    param3 = list(start = 1, end = nrow(df)), # defaults to include all rows of df
    param4 = c("start", "end"), # some longer description which has a length like this comment
    param5 = FALSE) {

  print("yada yada")
}

into this:

my_fun <- function(param1,
                   param2,
                   param3 = list(start = 1, end = nrow(df)), # defaults to include all rows of df
                   param4 = c("start", "end"), # some longer description which has a length like this comment
                   param5 = FALSE) {

   print("yada yada")
}

This creates long lines with over 100 characters. Anyway, is there a way to set up a config file to enforce double-indent style (https://style.tidyverse.org/functions.html#long-lines-1)?

There is currently an open issue for double indent with #845 but it's not implemented yet. So I'd consider that a duplicate of #845. Tangent issue: #247.

Just for clarification; as of now there is no way to config styler?

[lorenzwalthert]

There is a whole vignette on the topic of customization, but as far as double indent goes, you can't customize styler (unless you implement your own style guide).

Thanks for the link; there really should be a GETTING STARTED within the README.

I see that I can use transformers as an argument; yet, my question was related to having an external file such as: .stylerrc where I provide my own styler preferences without the need of repeating myself in function arguments.

Wooops; I just found this: #319. That was what I was looking for.
