Reframe CLI, revise quickstart, and reorganize tutorials #849

awwad · 2019-04-04T21:18:39Z

This PR:

correctly frames the CLI's current state as a tutorial toy.
provides a friendlier quickstart that puts what it's doing into perspective and guides you to next steps.
provides a better sense of what each tutorial/quickstart doc is for.
makes the getting started page slightly more friendly.
combines the two CLI docs, CLI.md and CLI_EXAMPLES.md
clarifies some installation instructions
other minor tweaks to the quickstart and CLI docs

The larger task this PR is part of is Issue #808.

CLI.md and CLI_EXAMPLES.md are really doing the same thing and should probably be merged into a single file: CLI_EXAMPLES.md, either in this PR or a later PR.

I think your changes/additions to the quickstart guide are really good (left a few minor comments inline). The overall structure of the various documents can still be improved as you point out aptly in #808.

+Unlike the underlying TUF modules that the CLI uses, the CLI itself is a bit
+bare-bones.  Using the CLI is the easiest way to familiarize yourself with

...? I think this is missing the end of the sentence.

Thanks. ^_^

docs/QUICKSTART.md

-`tufclient` directories are created in the current working directory.
+**Step (0)** - Make sure TUF is installed
+
+See the [installation instructions for TUF](docs/INSTALLATION.rst).


We are in the same directory INSTALLATION.rst. Remove docs form relative path or use absolute path.

Also, would it be bad to just provide the snippet here? So that quickstarters don't have to go through INSTALLATION.rst?

pip install tuf securesystemslib[crypto,pynacl]

They do need to go through the installation instructions to install TUF. Prior text was a bit misleading in that it suggested that they only needed to run the ssl install. In any case, that step is listed two lines down, to emphasize it, since it would otherwise be optional.

But isn't the line I'm suggesting all that's required for the quick start?

No, you need TUF installed.

Simplified. Installing pip produces everything you need already on a basic Ubuntu platform, so I didn't delve into python-dev or libssl-dev, etc. Just provided the single command in the QUICKSTART.

python-dev or libssl-dev

To contextualize, you need this to build the native support for the openssl backend. I think it's better to keep this from becoming a transient dependency as that may change at some point in the future...

I'm not clear on your suggestion, sorry: are you saying that we should avoid implicitly requiring that libssl-dev or similar packages be installed, or that we should avoid advising it explicitly since it may not be necessary? (Or something else?)

oh, the opposite. I understood that you were advising to remove these deps because something else is pulling them in. I'd rather have them explicitly just in case this is not the default in the future.

Currently, those requirements are now only in the collaborator docs, not in the installation docs. I was wondering if I should move them back into the installation docs. You're suggesting that we include them, which is good to hear, so I'll pull them back in to the natural place to put them (the installation instructions). I'll frame them as as-necessary installations, I guess, to try to keep things simple.

That's beyond the scope of this PR, so I'll just do that in the next one, but for this PR, I'll split the difference in QUICKSTART.md in anticipation of that change....

docs/QUICKSTART.md

 ```

-**Step (4)** - Fetch a target file from the repo.  The client downloads
-any required metadata and the requested target file.
+**Step (4)** - Obtain and verify the `testfile` update on a client.


minuscule nit-pick: You end some heading sentences with a period and other not.

docs/GETTING_STARTED.rst

- `CLI <CLI.md>`_
- `CLI Usage Examples <CLI_EXAMPLES.md>`_
- `Tutorial <TUTORIAL.md>`_
+- Beginner Tutorials (using the basic command-line interface): `Quickstart <QUICKSTART.md>`_; `CLI Tutorial <CLI.md>`_; `CLI Further Examples <CLI_EXAMPLES.md>`_


The long line looks a little daunting now. I would leave QUICKSTART.md separate and see if the cli tutorials could be combined, or restructured? From a quick glance, CLI.md looks like a documentation of the interface, whereas CLI_EXAMPLES.md looks like a slightly more in-depth version of QUICKSTART.md.

Fixed, and I've now combined the two CLI documents.

If you call it advanced tutorial here, which I think is a good idea, you maybe also want to call it that in the document heading?

Fixed there and elsewhere, thanks.

@awwad It's because cryptography manylinux1 wheel bundles its own copy of OpenSSL, unless you use something glib-c incompatible, like Alpine
