Make company-mode support for nginx-mode

1 At the beginning

I'm learning a little about Nginx recently, I hope can setup web server by myself when someday I want to build up a website for startup or something else.

Like Ansible, Terraform, they all have keywords completions support.

Emacs already has an major mode nginx-mode, but it does not provide Nginx directives completion. I know company-mode has company-keywords-alist. So I can support for Nginx too.

2 Fetch all Nginx directives

2.1 TODO Elisp implementation

(require 'elquery)

(with-current-buffer (url-retrieve-synchronously "https://nginx.org/en/docs/dirindex.html")
  (message "%S"
           (elquery-$ "body #main #content p"
                      (elquery-read-string (buffer-string)))))

(let ((html (with-current-buffer
                (set-buffer-multibyte nil)
              (url-retrieve-synchronously "https://nginx.org/en/docs/dirindex.html")
              (elquery-read-string
               (buffer-string)))))
  (elquery-$ "#content p" html))

NOTE: This version does not work, because some low-level reason.

2.2 another Python implementation

import urllib.request
import urllib.parse
import bs4

req = urllib.request.Request("https://nginx.org/en/docs/dirindex.html")
respond = urllib.request.urlopen(req)
html_page = respond.read().decode("utf-8")
parsed_html = bs4.BeautifulSoup(html_page, "html")
p = parsed_html.find('div', attrs={'id': 'content'}).find('p')
# print(p)

a = p.find_all('a')
# print(a)

directives = []

for x in a:
    directives.append(x.text)

print(directives)
