allow specifying a custom pypi url

[wbolster]

the pypi url is currently hardcoded, which makes it impossible to use this package properly with custom pypi repos (e.g. devpi). adding a customizable variable would be a solution for this. an auto-detect feature that uses the pip config file to obtain the index-url would be even better... :)

I can fix that. I'll open a PR, if I find the time.

also there's PIP_INDEX_URL env var

hey @Wilfred thanks for picking this up.

that said, 216cd16 does not actually respect any of the configuration files or env vars, so this doesn't really ‘work out of the box’.

any advice on getting it working automatically?

[Wilfred]

How about something like this?

(require 'subr-x)

(defun wh/set-url-from-pip ()
  (setq
   pip-requirements-index-url
   (string-trim
    (shell-command-to-string
     "pip config get global.index-url"))))

(add-hook 'pip-requirements-mode-hook
          #'wh/set-url-from-pip)

This will set the variable every time you open a new requirements file.
