Handle --requirement argument, not just -r

Lines 158 to 160 in 110c931

	req_option = '-r'
	if dep_name.startswith(req_option):
	return dep_name[len(req_option):]

is great, but doesn't handle the long-form option:

[testenv:test]
deps =
    --no-deps
    --requirement deps/test.txt

This would be a good issue for someone to handle for Hacktoberfest 😄

@Zac-HD indeed it doesn't. Thank you for reporting.

I haven't seen usage of --no-deps before.
Does tox config skipsdist work for you?

[Zac-HD]

No problem 😄

--no-deps means "install exactly the packages listed, and nothing else - not even their dependencies". It's obviously only useful with lockfiles, but important in case e.g. your lockfile was missing something which would then not be properly locked. So tox's skipsdist is really a separate thing - --no-deps isn't related to this issue, it's just something I have in my config.

While I think about it, it would be good to handle all of the following cases - currently only file1.txt-style is supported:

[testenv]
deps =
    -rfile1.txt
    -r file2.txt
    -r=file3.txt
    --requirement file4.txt
    --requirement=file5.txt
