Get R styler package to remember settings-CodePudding

I am trying to get the r package styler to remember a simple alteration to tidyverse_style(), i.e.

styler::tidyverse_style(indent_by = 4L)

When using the rstudio addin tab addins > Set style and inputting the above option, styler remembers to indent by 4 spaces for each tab, but forgets this setting when Rstudio is closed.

If I input the above line in the console, it does not remember the 4L indentation at all, defaulting to 2L.

I have tried caching and that doesn't work, probably because all it is used for is to prevent redundant linting.

> styler::cache_activate()
Using cache 1.9.0 at C:\Users\<user>\AppData\Local\R\cache\R\R.cache/styler/1.9.0.
> styler::cache_info()

I have trawled through the documentation and cannot find a simple way to store styler settings and call it up everytime Rstudio starts up. It would be silly if the only way to do this is to write a styler package and import it with library(mystyle).

CodePudding user response：

From the documentation of the styler package you have to set styler.addins_style_transformer in your .Rprofile:

The style transformers are memorized within an R session via the R option styler.addins_style_transformer so if you want it to persist over sessions, set the option styler.addins_style_transformer in your .Rprofile.

Following the example in the docs add e.g.

val <- "styler::tidyverse_style(indent_by = 4L)"
options(
  styler.addins_style_transformer = val
)

to your .Rprofile.
