Add control over where files are appended inside zip irrespective of source path #117
Description
It would be really nice if I could specify where in the zip file I want another file to be added without needing that file to already be in a directory structure mirroring what I want in the zip file.
For example, if I have a zip file called file.zip and inside the zip file is the directory test and I want to add file2 inside the test folder of file.zip. As far as I can tell, I need to first move file2 into a folder named test and then I can use zip_append() to add it to the test folder of file.zip.
Using the example from the help file:
## Some files to zip up. We will run all this in the R session's
## temporary directory, to avoid messing up the user's workspace.
dir.create(tmp <- tempfile())
dir.create(file.path(tmp, "mydir"))
cat("first file", file = file.path(tmp, "mydir", "file1"))
cat("second file", file = file.path(tmp, "mydir", "file2"))
zipfile <- tempfile(fileext = ".zip")
zip::zip(zipfile, "mydir", root = tmp)
## List contents
zip_list(zipfile)
## Add another file outside "mydir"
cat("third file", file = file.path(tmp, "file3"))
# Say I want to add the file to "mydir" inside the zip file how can I do that here?
# As-is this will add file3 to the root of the zip file.
# zip_append(zipfile, "file3", root = tmp)
# zip_list(zipfile)
