infix operators don't conform to tidyverse standards

[nathaneastwood]

I have found a difference between lintr and styler. styler will correct the following

(10 ^ (x - 1)) + 1

to

(10^(x - 1)) + 1

This gives the following lintr errors:

Put spaces around all infix operators.
Place a space before left parenthesis, except in a function call.

Looking at the current tidyverse style guide, styler is correct here. To get around this you can use

styler::style_pkg(".", math_token_spacing = list(one = c("'^'", "'+'", "'-'", "'*'", "'/'")))

A similar issue exists with

break ()

which gets corrected to

break()

by styler. I am not sure which is correct with regards to the tidyverse here.

The ^ behavior is a bug, PR are welcome.

break is a statement, not a function call, so you should not have () in your code at all in this case.

Quick question: I noticed that this fix is not present on the CRAN version, which is around 6 months more recent than the fix itself. Any idea what happened?

Hello, I believe this is still an issue:

x^(y + z)

lintr_2.0.1 still says

Place a space before left parenthesis, except in a function call.
