This =kiwix.el= supports query =kiwix-tools='s =kiwix-serve= server through URL API.

The =kiwix-serve= server can be started from command-line if you have =kiwix-tools=
installed, or from Docker container [fn:1].

* Setup kiwix-serve

If you use kiwix-serve Docker container, you can create an Systemd unit service
to auto start Docker container. Here is the systemd unit config file:

** Dockerize kiwix-tools (kiwix-serve, etc)

How to run?

Given =wikipedia.zim= ([[#ZIM][Zim database files]]) resides in =/tmp/zim/=, execute the
following command:

#+begin_src sh :eval no
# if you don't have libraries index file "library.xml"
docker container run -d --name kiwix-serve -v /tmp/zim:/data -p 8080:80 kiwix/kiwix-serve wikipedia.zim
# if you have libraries index file "library.xml"
docker container run -d --name kiwix-serve -v /tmp/zim:/data -p 8080:80 kiwix/kiwix-serve --library library.xml

*NOTE*: You can generate the libraries index file "library.xml" with following command:

#+begin_src sh
cd ~/

for zim in $(ls *.zim); do
  kiwix-manage library.xml add $zim

*NOTE*: Using the libraries index file method, you can have all libraries served
in Docker container instead of just one library.

If you put ZIM files in other places not =/tmp/zim/=, you can use follow my command:

#+NAME: create kiwix-serve container with custom port
#+begin_src sh :session "*kiwix-serve*"
docker container run -d \
       --name kiwix-serve \
       -v ~/ \
       -p 8089:80 \
       kiwix/kiwix-serve wikipedia_zh_all_2015-11.zim

Visit http://localhost:8080 or http://localhost:8089 (if you exposed different

For easy launch the docker run command, you can add command alias in shell profile:

#+begin_src shell :eval no
alias kiwix-docker-wikipedia_zh_all="docker container run --name kiwix-serve -d -v ~/ -p 8089:80 kiwix/kiwix-serve wikipedia_zh_all_2015-11.zim"
alias kiwix-docker-wikipedia="docker container run --name kiwix-serve -d -v ~/ -p 8089:80 kiwix/kiwix-serve wikipedia.zim"

*NOTE*: Because =kiwix-serve.service= use command =docker container start

* Config

** use-package

#+begin_src emacs-lisp
(use-package kiwix
  :ensure t
  :after org
  :custom ((kiwix-server-use-docker t)
           (kiwix-server-port 8089)

  :commands (kiwix-launch-server kiwix-at-point)
  :init (require 'org-kiwix)
  :config (add-hook 'org-load-hook #'org-kiwix-setup-link))

* Usage

** Use in Emacs

=[M-x kiwix-at-point]=

** Org Mode integration

#+begin_src emacs-lisp
(require 'org-kiwix)

=[C-c C-l]= to insert link.

The link format is like this:


The =(library)= can be =wikipedia_en=, =wikipedia_zh=, =wiktionary_en=, or =en=, =zh= etc.

** EWW integration

Set following option in your config to use EWW in Emacs as your default _for
Kiwix only_.

#+begin_src emacs-lisp
(setq kiwix-default-browser-function 'eww-browse-url)

* Changelog

** DONE implemented async instantly input suggestion completion in Ivy
   CLOSED: [2019-10-08 Tue 22:07]
   - State "DONE"       from              [2019-10-08 Tue 22:07]

This feature is very subtle :)

* Test

- [[wikipedia:Operations%20Research][Operations Research]] :: query contains space.
- [[wikipedia:Operations%20research][Operations research]] :: the second word is not capitalized.
- [[wikipedia:%E4%B8%AD%E5%9B%BD][中国]] :: non-english query
- [[wikipedia:meta-circular%20interpreter][meta-circular interpreter]] :: only capitalize the first word.

* How does this extension work?

** integrate with Emacs

*** core

I found Kiwix will return a URL like this:

____________________  _____________________  __  _____________________________

< server address >    < library >                <one of the returned results>

*** steps

1. auto start ~kiwix-serve~ HTTP server.
2. query/search on kiwix server.
   1. open kiwix server index page to input to search. (But this is slow, waste time)
   2. use http language binding library to query on kiwix HTTP server.
      1. select library in library list page.
      2. after load a library, simulate type query string in the search input
         box, the submit to search.
      3. return the result page HTML or page URL.
      4. view the result with page URL or page HTML with Emacs browser.

*** auto start kiwix HTTP server

Here is a simple script, you can put it in Linux "*auto-start*".

#+begin_src org
,#+BEGIN_SRC sh :tangle "~/scripts/"
#!/usr/bin/env sh

/usr/lib/kiwix/bin/kiwix-serve --library --port=8000 --daemon ~/

*** search

1. kiwix-search command -> return a list of results.

   #+begin_src org
   ,#+BEGIN_SRC sh
   /usr/lib/kiwix/bin/kiwix-search ~/ linux

2. use one element of list as part of the URL.

   #+begin_src org
   ,#+BEGIN_SRC emacs-lisp
   (browse-url (concat "" "LIBRARY" "/A/" "RESULT"))

*** more advanced?

If you want more advanced functions, you can use communicate kiwix HTTP server
with RESTful API.

- I don't know what Emacs library to use.
- Or you can use other language to do this, like Ruby or Python etc.
