golem copied to clipboard

When passing multiple arguments to the functions, the function will fail.

colin:golem colin$ cd /tmp/
colin:tmp colin$ Rscript -e "golem::create_golem('pouet')"

A new golem named pouet was created at /private/tmp/pouet .
To continue working on your app, start editing the 01_start.R file.
colin:tmp colin$ cd pouet/
colin:pouet colin$ Rscript -e "golem::add_module(c('plif', 'plouf'))"

• Go to R/mod_plif.R

Should these functions:

• Take only the first value of the vector or
• Fail gracefully

I think we should fail gracefully.

attempt::stop_if(name, ~ length(.x) > 1, "Name should be of length 1")

Other idea, vectorized versions :

golem::add_modules()
golem::add_css_files()
etc.
