Add a function show_dplyr() that prints the resulting dplyr code instead of running it.

ianmcook commented 4 years ago

The current implementation of show_dplyr() has the following known issue:

Inside calls to functions with more than 5 arguments passed to them, all arguments beyond the 5th are truncated in the printed dplyr code. This is caused by truncation logic in rlang:::list_deparse().

I documented the argument truncation behavior and added a test for it in c1aee8c.

I opened an rlang PR to control the truncation behavior https://github.com/r-lib/rlang/pull/897

I made changes to prepare for r-lib/rlang#897 in 77c12a4
