Setup 5.x in a single folder as setup.py used to do

[Dan'l B]

It seems to me I saw a comment that using a venv it is still possible to enable the setup to locate all weewx files in a single folder, as setup.py used to do.

I've looked through the wiki and docs and can't find anything.

Can this be done?

stations are separate data (by definition) but can have shared code base e.g.

  ~weewx/venv/

  ~weewx/station1/

  ~weewx/station2/

A pip installation all goes in the $HOME directory of the user that ran pip, so it's all in one directory (/home/pi or whatever) that has two subdirectories underneath. 

• $HOME/weewx-venv is where the code of core weewx goes (don't mess under there).
  
• $HOME/weewx-data is where skins, installed extensions/services, the database(s) and any generated output files go (you 'can' edit under there)
  

The 'weewx-venv' name above is what the pip quickstart uses as a name for the venv. You can use whatever name there you want if desired.

If you really want to recreate what setup.py did, you can try

pip install --target /home/weewx/bin weewx

python3 /home/weewx/bin/weectl.py station create /home/weewx

Normally, pip installs into the site-packages subdirectory of whatever instance of python you are using.  The first line tells pip to install into /home/weewx/bin instead. 

The second line says to create a new station under the directory /home/weewx. So the configuration file, skins, archive database, etc, will all be put in /home/weewx

The results will approximate an old setup.py install with a couple of differences:

1. Everything will be put in /home/weewx. That is, not just the weewx code, but also its dependencies.

2. The files weewxd.py and weectl.py are not executable. You have to give them as an argument to python3. For example,

    python3 /home/weewx/bin/weewxd.py /home/weewx/weewx.conf

Vince, Tom,

Thanks for the pointers. I am getting used to the VENV way of installing WeeWx so your advice was invaluable.
