### Client Configuration
You can configure the client (the JS part) via `data-` attributes:
* data-title
When you start a new thread (= first comment on a page), Isso sends
a GET request that page to see if it a) exists and b) parse the site's
heading (currently used as subject in emails).
Isso assumes that the title is inside an `h1` tag near the isso thread:
```html
<html>
<body>
<h1>Website Title</h1>
<article>
<header>
<h1>Post Title</h1>
<section id="isso-thread">
...
```
In this example, the detected title is `Post Title` as expected, but some
older sites may only use a single `h1` as their website's maintitle, and
a `h2` for the post title. Unfortunately this is unambiguous and you have
to tell Isso what's the actual post title:
```html
<section data-title="Post Title" id="isso-thread">
```
Make sure to escape the attribute value.
* data-isso
Isso usually detects the REST API automatically, but when you serve the JS
script on a different location, this may fail. Use `data-isso` to
override the API location:
```html
<script data-isso="/isso" src="/path/to/embed.min.js"></script>
```
* data-isso-css
Set to `false` prevents Isso from automatically appending the stylesheet.
Defaults to `true`.
```html
<script src="..." data-isso-css="false"></script>
```
* data-isso-lang
Override useragent's preferred language. Currently available: german (de),
english (en) and french (fr).
* data-isso-reply-to-self
Set to `true` when spam guard is configured with `reply-to-self = true`.
### Webserver configuration
* nginx configuration to run Isso on `/isso`:

Isso API
========
The Isso API uses HTTP and JSON as primary communication protocol.
## JSON format
When querying the API you either get an error, an object or list of objects
representing the comment. Here's a example JSON returned from Isso:
```json
{
"text": "Hello, World!",
"author": "Bernd",
"website": null,
"votes": 0,
"mode": 1,
"id": 1,
"parent": null,
"hash": "68b329da9893e34099c7d8ad5cb9c940",
"created": 1379001637.50,
"modified": null
}
```
text
: required, comment as HTML
author
: author's name, may be `null`
website
: author's website, may be `null`
votes
: sum of up- and downvotes, defaults to zero.
mode
: * 1, accepted comment
* 2, comment in moderation queue
* 4, comment deleted, but is referenced
id
: unique comment number per thread
parent
: answer to a parent id, may be `null`
hash
: user identification, used to generate identicons
created
: time in seconds sinde epoch
modified
: last modification time in seconds, may be `null`
## List comments
List all visible comments for a thread. Does not include deleted and
comments currently in moderation queue.
GET /?uri=path
You must encode `path`, e.g. to retrieve comments for `/hello-world/`:
GET /?uri=%2Fhello-world%2F
To disable automatic Markdown-to-HTML conversion, pass `plain=1` to the
query URL:
GET /?uri=...&plain=1
As response, you either get 200, 400, or 404, which are pretty self-explanatory.
GET /
400 BAD REQUEST
GET /?uri=%2Fhello-world%2F
404 NOT FOUND
GET /?uri=%2Fcomment-me%2F
[{comment 1}, {comment 2}, ...]
## Create comments
...
## Delete comments

Client Configuration
====================
You can configure the client (the JS part) with custom data attributes,
preferably in the script tag which embeds the JS:
.. code-block:: html
<script data-isso="/prefix/"
data-isso-css="true"
data-isso-lang="ru"
data-isso-reply-toself="false"
src="/prefix/js/embed.js"></script>
Furthermore you can override the automatic title detection inside
the embed tag, e.g.:
.. code-block:: html
<section id="isso-thread" data-title="Foo!"></section>
data-isso
---------
Isso usually detects the REST API automatically, but when you serve the JS
script on a different location, this may fail. Use `data-isso` to
override the API location:
.. code-block:: html
<script data-isso="/isso" src="/path/to/embed.min.js"></script>
data-isso-css
-------------
Set to `false` prevents Isso from automatically appending the stylesheet.
Defaults to `true`.
.. code-block:: html
<script src="..." data-isso-css="false"></script>
data-isso-lang
--------------
Override useragent's preferred language. Currently available: german (de),
english (en) and french (fr).
data-isso-reply-to-self
-----------------------
Set to `true` when spam guard is configured with `reply-to-self = true`.

Multiple Sites
--------------
Isso is designed to serve comments for a single website and therefore stores
comments for a relative URL to support HTTP, HTTPS and even domain transfers
without manual intervention. But you can chain Isso to support multiple
websites on different domains.
The following example uses `gunicorn <http://gunicorn.org/>`_ as WSGI server (
you can use uWSGI as well). Let's say you maintain two websites, like
foo.example and other.foo:
.. code-block:: bash
$ cat /etc/isso.d/foo.example.cfg
[general]
host = http://foo.example/
dbpath = /var/lib/isso/foo.example.db
$ cat /etc/isso.d/other.foo.cfg
[general]
host = http://other.foo/
dbpath = /var/lib/isso/other.foo.db
Then you run Isso using gunicorn:
.. code-block:: bash
$ export ISSO_SETTINGS="/etc/isso.d/foo.example.cfg;/etc/isso.d/other.foo.cfg"
$ gunicorn isso.dispatch -b localhost:8080
In your webserver configuration, proxy Isso as usual:
.. code-block:: nginx
server {
listen [::]:80;
server_name comments.example;
location / {
proxy_pass http://localhost:8080;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
}
}
To verify the setup, run:
.. code-block:: bash
$ curl -vH "Origin: http://foo.example" http://comments.example/
...
$ curl -vH "Origin: http://other.foo" http://comments.example/
...
In case of a 418 (I'm a teapot), the setup is *not* correctly configured.

Setup
=====
Sub-URI
-------
You can run Isso on the same domain as your website, which circumvents issues
originating from CORS_. Also, privacy-protecting browser addons such as
`Request Policy`_ wont block comments.
.. code-block:: nginx
server {
listen [::]:80;
listen [::]:443 ssl;
server_name example.tld;
root /var/www/example.tld;
location /isso {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Script-Name /isso;
proxy_pass http://localhost:8080;
}
}
Now, the website integration is just as described in :doc:`../quickstart` but
with a different location.

Isso API
========
The Isso API uses HTTP and JSON as primary communication protocol.
JSON format
-----------
When querying the API you either get an error, an object or list of
objects representing the comment. Here's a example JSON returned from
Isso:
.. code-block:: js
{
"text": "Hello, World!",
"author": "Bernd",
"website": null,
"votes": 0,
"mode": 1,
"id": 1,
"parent": null,
"hash": "68b329da9893e34099c7d8ad5cb9c940",
"created": 1379001637.50,
"modified": null
}
text : required, comment as HTML
author : author's name, may be ``null``
website : author's website, may be ``null``
votes : sum of up- and downvotes, defaults to zero.
mode : \* 1, accepted comment \* 2, comment in moderation queue \* 4,
comment deleted, but is referenced
id : unique comment number per thread
parent : answer to a parent id, may be ``null``
hash : user identification, used to generate identicons
created : time in seconds sinde epoch
modified : last modification time in seconds, may be ``null``
List comments
-------------
List all visible comments for a thread. Does not include deleted and
comments currently in moderation queue.
GET /?uri=path
You must encode ``path``, e.g. to retrieve comments for
``/hello-world/``:
::
GET /?uri=%2Fhello-world%2F
To disable automatic Markdown-to-HTML conversion, pass ``plain=1`` to
the query URL:
::
GET /?uri=...&plain=1
As response, you either get 200, 400, or 404, which are pretty
self-explanatory.
::
GET /
400 BAD REQUEST
GET /?uri=%2Fhello-world%2F
404 NOT FOUND

uWSGI
=====
In short: `uWSGI <http://uwsgi-docs.readthedocs.org/>`_ is awesome. Isso
has builtin support for it (and simple fallback if uWSGI is not
available). Use uWSGI if you think that the builtin WSGI server is a bad
choice or slow (hint: it's both).
With uWSGI, you have roughly 100% performance improvements for just
using it. Instead of one thread per request, you can use multiple
processes, hence it is more "web scale". Other side effects: spooling,
fast inter-process caching.
Installation
------------
You need uWSGI 1.9 or higher, fortunately you can install it with
Python:
.. code-block:: sh
~> apt-get install build-essential python-dev
~> pip install uwsgi
Configuration
-------------
For convenience, I recommend a INI-style configuration (you can also
supply everything as command-line arguments):
.. code-block:: ini
[uwsgi]
http = :8080
master = true
processes = 4
cache2 = name=hash,items=1024,blocksize=32
spooler = %d/mail
module = isso
virtualenv = %d
env = ISSO_SETTINGS=%d/sample.cfg
You shoud adjust ``processes`` to your CPU count. Then, save this file
to a directory if choice. Next to this file, create an empty directory
called ``mail``:
.. code-block:: sh
~> mkdir mail/
~> ls
uwsgi.ini mail/
Now start Isso:
.. code-block:: sh
~> uwsgi /path/to/uwsgi.ini

Overview
========
Welcome to the Isso's documentation. This documentation will help you get
started fast. If you get any problems when using Isso, you can find the answer
in troubleshooting or you can ask me on IRC or GitHub.
What's Isso?
------------
Isso is a lightweight commenting server similar to Disqus. It allows anonymous
comments, maintains identity and is simple to administrate. It uses JavaScript
and cross-origin ressource sharing for easy integration into static websites.
No, I meant "Isso"
------------------
Isso is an informal, german abbreviation for "Ich schrei sonst!", which can
roughly be translated to "I'm yelling otherwise". It usually ends the
discussion without any further arguments.
In germany, Isso `is also pokémon N° 360`__.
.. __: http://bulbapedia.bulbagarden.net/wiki/Wynaut_(Pok%C3%A9mon)
What's wrong with Disqus?
-------------------------
No anonymous comments (IP address, email and name recorded), hosted in the USA,
third-party. Just like IntenseDebate, livefrye etc. When you embed Disqus, they
can do anything with your readers (and probably mine Bitcoins, see the loading
times).
Isso is not the first open-source commenting server:
* `talkatv <https://github.com/talkatv/talkatv>`_, written in Python.
Unfortunately, talkatv's (read "talkative") development stalled. Neither
anonymous nor threaded comments.
* `Juvia <https://github.com/phusion/juvia>`_, written in Ruby (on Rails).
No threaded comments, nice administration webinterface, but... yeah... Ruby.
* `Tildehash.com <http://www.tildehash.com/?article=why-im-reinventing-disqus>`_,
written in PHP. Did I forgot something?
* `Unobtrusive, self-hosted comments <http://stackoverflow.com/q/2053217>`_,
discussion on StackOverflow.

Quickstart
==========
Assuming you have successfully :doc:`installed <install>` Isso, here's
a quickstart quide that covers common setups.
Configuration
-------------
You must provide a custom configuration. Most default parameters are useful for
development, not persistence. Two most important options are `dbpath` to set
the location of your database and `host` which is your website:
.. code-block:: ini
[general]
; database location, check permissions
dbpath = /var/lib/isso/comments.db
; your website or blog (not the location of Isso!)
host = http://example.tld/
; you can add multiple hosts for local development
; or SSL connections. There is no wildcard to allow
; any domain.
host =
http://localhost:1234/
http://example.tld/
https://example.tld/
Note, that multiple, *different* websites are **not** supported in a single
configuration. To serve comments for diffent websites, refer to
:ref:`Multiple Sites <configure-multiple-sites>`.
You moderate Isso through signed URLs sent by email or logged. By default,
comments are accepted and immediately shown to other users. To enable
moderation queue, add:
.. code-block:: ini
[moderation]
enabled = true
To moderate comments, either use the activation or deletion URL in the logs or
:ref:`use SMTP <configure-smtp>` to get notified on new comments including the
URLs for activation and deletion:
.. code-block:: ini
[general]
notify = smtp
[smtp]
; SMTP settings
Migration
---------
You can migrate your existing comments from Disqus_. Log into Disqus, go to
your website, click on *Discussions* and select the *Export* tab. You'll
receive an email with your comments. Unfortunately, Disqus does not export
up- and downvotes.
To import existing comments, run Isso with your new configuration file:
.. code-block:: sh
~> isso -c /path/to/isso.cfg import user-2013-09-02T11_39_22.971478-all.xml
[100%] 53 threads, 192 comments
.. _Disqus: <https://disqus.com/>
Running Isso
------------
To run Isso, simply execute:
.. code-block:: sh
$ isso -c /path/to/isso.cfg run
2013-11-25 15:31:34,773 INFO: connected to HTTP server
Next, we configure Nginx_ to proxy Isso. Do not run Isso on a public interface!
A popular but often error-prone (because of CORS_) setup to host Isso uses a
dedicated domain such as ``comments.example.tld``; see
:doc:`configuration/setup` for alternate ways.
Assuming both, your website and Isso are on the same server, the nginx
configuration looks like this:
.. code-block:: nginx
server {
listen [::]:80 default ipv6only=off;
server_name example.tld;
root ...;
}
server {
listen [::]:80;
server_name comments.example.tld;
location / {
proxy_pass http://localhost:8080;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
Now, you embed Isso to your website:
.. code-block:: html
<script data-isso="http://comments.example.tld/"
src="http://comments.example.tld/js/embed.min.js"></script>
<section id="isso-thread"></section>
Note, that `data-isso` is optional, but when a website includes a script using
``async`` it is no longer possible to determine the script's external URL.
That's it. When you open your website, you should see a commenting form. Leave
a comment to see if the setup works. If not, see :doc:`troubleshooting`.

Deployment
----------
Isso ships with a built-in web server, which is useful for the initial setup.
But it is not recommended to use the built-in web server for production. A few
WSGI servers are supported out-of-the-box:
* gevent_, coroutine-based network library
* uWSGI_, full-featured uWSGI server
* gunicorn_, Python WSGI HTTP Server for UNIX
.. _gevent: http://www.gevent.org/
.. _uWSGI: http://uwsgi-docs.readthedocs.org/en/latest/
.. _gunicorn: http://gunicorn.org/
gevent
^^^^^^
Probably the easiest deployment method. Install with PIP (requires libevent):
.. code-block:: sh
$ pip install gevent
Then, just use the ``isso`` executable as usual. Gevent monkey-patches Python's
standard library to work with greenlets.
To execute Isso, just use the commandline interface:
.. code-block:: sh
$ isso -c my.cfg run
Unfortunately, gevent 0.13.2 does not support UNIX domain sockets (see `#295
<https://github.com/surfly/gevent/issues/295>`_ and `#299
<https://github.com/surfly/gevent/issues/299>`_ for details).
uWSGI
^^^^^
The author's favourite WSGI server. Due the complexity of uWSGI, there is a
:doc:`separate document <extras/uwsgi>` on how to setup uWSGI for use
with Isso.
gunicorn
^^^^^^^^
Install gunicorn_ via PIP:
.. code-block:: sh
$ pip install gunicorn
To execute Isso, use a command similar to:
.. code-block:: sh
$ export ISSO_SETTINGS="/path/to/isso.cfg"
$ gunicorn -b localhost:8080 -w 4 --preload isso

uWSGI
=====
In short: [uWSGI](http://uwsgi-docs.readthedocs.org/) is awesome. Isso has
builtin support for it (and simple fallback if uWSGI is not available). Use
uWSGI if you think that the builtin WSGI server is a bad choice or slow (hint:
it's both).
With uWSGI, you have roughly 100% performance improvements for just using it.
Instead of one thread per request, you can use multiple processes, hence it
is more "web scale". Other side effects: spooling, fast inter-process caching.
Installation
------------
You need uWSGI 1.9 or higher, fortunately you can install it with Python:
```sh
~> apt-get install build-essential python-dev
~> pip install uwsgi
```
Configuration
-------------
For convenience, I recommend a INI-style configuration (you can also supply everything
as command-line arguments):
```ini
[uwsgi]
http = :8080
master = true
processes = 4
cache2 = name=hash,items=1024,blocksize=32
spooler = %d/mail
module = isso
virtualenv = %d
env = ISSO_SETTINGS=%d/sample.cfg
```
You shoud adjust `processes` to your CPU count. Then, save this file to a directory
if choice. Next to this file, create an empty directory called `mail`:
```sh
~> mkdir mail/
~> ls
uwsgi.ini mail/
```
Now start Isso:
```sh
~> uwsgi /path/to/uwsgi.ini
```
