Pack one file

[SHAESEN2]

When packing only one file, I get an error that I traced back to the following piece of code:

idx_content_end <- c(idx_pkg[2L:nblocks] - 2L, nlines)

This line of code identifies the end of each block. If you have three files packed in the .txt file it will look for:

• the start of the second block of content = end of first block
• the start of the third block of content = end of second block
• the end of the .txt file = end of third block

When you only pack one file, this logic does not work because nblocks is 1.

This can be solved by eg

if (nblocks == 1) { idx_content_end <- c(nlines) } else if (nblocks>1) { idx_content_end <- c(idx_pkg[2L:nblocks] - 2L, nlines) }

It would be good to include a unit test for this.

So if you have one file, does it make more sense to use/exchange it as-is? Just a thought 🤔

Alternatively, you could build an R package for it, which (I know) is a huge ask sometimes... but that will almost surely make it more than two or three files.

It makes sense for experimentation and training purposes. If you are not inclined to add a few lines of code to fix the issue, could you consider adding an informative message or documenting the behavior?

Hmm, good question, but after some rethinking, I'm still going to say no, and here is my reasoning:

1. For experimentation and training purposes, any R package scaffolding tool such as usethis::create_package() that creates a proper package will create more than one file.
2. It's common sense that more that one file will be involved under the context of packing a proper R package, so emphasizing an expected behavior would sound a bit unnecessary to me.

Thanks for bringing this up, though!
