845 path/pkg arg consistency

[ilyaZar]

fixes #845

Maybe path is a bit more general because it can be used for files and package-dirs, but the issue suggests pkg.

I have made a commit per file to identify the instances so if required one can quickly change from pkg back to path.

DONE: path - > pkg changes

• R/golem-yaml-get.R
• R/config.R
• R/golem-yaml-set.R
• R/is_golem.R
• R/pkg_tools.R

TO-DO: decide here I do not think pkg makes sense because:

1. sometimes path is a path to a file so pkg is just weird:
   - utils.R - > create_if_needed()-dance for files
   - use_file.R - > template files
   - use_favicon.R - > path to favicon files
   - templates.R - > all functions refer to template files I think
   - modules_fn.R - > module_template() it does use a path to a file
   - add_r_files.R - > append_roxygen_comment() path to the R script where the module will be
   - bundle_resources.R - > bundle_resources() needs a path to a subdir, not the package
   - config.R - > everything but the last function attempts to find a config-file trying different paths
   - create_golem.R - > creates a golem in the specified path and the package_name can be seperately
   - enable_roxygenize -> path to .Rproj file

2. for bootstrapped functions, same as above, plus their args are already named path, I wouldn’t want to change that:

   • bootstrap_fs.R
   • bootstrap_attachment.R
   • bootstrap_dockerfiler.R
   • bootstrap_pkgload.R
   • bootstrap_usethis.R

Thanks a lot @ilyaZar, I'll cherry pick this and merge.

You're right about not changing some of the args, as far as I can tell the idea is to have a consistency in user-facing functions where we need to refer to a path to a working directory.

And all things considered, I'm thinking about switching to an arg called golem_wd, so that it's clear what we are talking about :)

@ColinFay allright thanks! let me know which of the commits you'd like to cherry pick (i.e. which of the files basically).

and when you decide on golem_wd or another name, I can make changes to my branch (current pull of upstream dev plus name changes to golem_wd) or squash/separate commits if it helps with the merge

cheers
