pypi package does not install the command "traad" #71

Closed PythonNut closed 9 years ago

PythonNut commented 9 years ago

Ideally, users should be able to install traad with just pip and package.el.

Another thing that would be nice is an emacs traad-install-server function that installs the server automatically.

abingham commented 9 years ago

pip definitely installs the traad command when I use it. Are you using Python3? If so, then it actually installs the command traad3, not traad, so maybe this is causing some confusion.

If you're absolutely sure that the setup.py included with traad isn't properly installing the traad or traad3 command, tell me your Python version, operating system, and the commands you're using to install it.

Regarding installation of traad for the user, that's something I've considered but never had the time to dive into. I know that jedi does it by using the python-environment library, and since traad is pure Python I think we could follow the same path. Do you have any interesting in trying to implement this feature?

abingham commented 9 years ago

(I'm going to make a few notes about this feature.)

We need to make sure we concurrently support both Python2 and Python3. Ultimately, it may be simplest to support arbitrary virtual environments since people may need sub-major-version support. When we design this support in, we need to think about the future possibility of automatically detecting Python versions.
We need to continue to work properly with traad's installed manually. When there's a conflict between auto-installed and manually-installed traads, we should favor the auto-installed version, i.e. it's OK to make it inconvenient to use a manual install.
See jedi for an example of how to approach this feature.

Ah, indeed. Thanks for being so responsive. I suppose this has become sort of like #50.

traad is now working for me, and I'm happy using it. You might want to document that traad is on pypi, because that makes me feel safer and more correct for some reason.

abingham commented 9 years ago

Thanks for the feedback. I've updated the wiki to instruct people to use pip unless they have a good reason no to.

abingham commented 9 years ago

I've added the traad-install-server command and supporting infrastructure. Once it's up in melpa, give it a shot and let me know if it works for you.

PythonNut commented 9 years ago

It works fine for me, as far as I can tell.

abingham commented 9 years ago

@PythonNut Excellent, thanks for letting me know.

Are you by any chance using traad with Python3? I've recently started seeing very (very) strange bugs that only seem to manifest when I'm talking to a Python3 traad server. The bug is that emacs gets an unbalance bytecode stack, so it seems extremely unlikely that Python 3 is involved in any way, but I'm trying to see if anyone else is having problems. I started seeing these problems after I made this change, though that may just be coincidence.

PythonNut commented 9 years ago

I don't actually know how to use traad with Python3. Is it as simple as opening a Py3 file and doing everything normally?

abingham commented 9 years ago

Unfortunately it's a bit complex. You have to install traad with Python 3 (eg with a Python 3 virtual environment) and then make sure your using that environment when you call traad-open.

The readme and wiki should cover this, but let me know of it's unclear. I'm on vacation right now, so I may not be able to give great support for the next few weeks.
