Fork c2p2_template

The easiest way to start is to fork this template: https://github.com/nanvel/c2p2-template.

Templates API

The application looks for templates inside SOURCE_FOLDER, so we need to add them. Minimal list of files required is:

- site
    - engine
        - templates
            - 404.html
            - 500.html
            - index.html
            - page.html
            - label.html
            - sitemap.xml

index.html, page.html, label.html and sitemap.xml receives, beside tornado standart template context, variable c, that uses to access a list of pages and labels, for example:

{{ c.page }}
{{ c.page.title }}
{{ c.page.labels }}
{{ c.label }}
{% for page in c.pages %}
{{ c.pages['<page_slug>'] }}
{{ c.pages.for_label('<label_slug>') }}

c.page is available only in page.html. It returns current page object.

Page object has next attributes:

• uri

• html

• created

• modified

• title

• meta

• labels

page.meta returns PageMeta object, where all variables specified in the top of the page is available.

// page.md
created: 2015-10-10T00:00
show_comments: true
labels: Label1
        Label2

// page.html
{{ c.page.meta.created }} -> '2015-10-10T00:00'
{{ c.page.meta.created }} -> '2015-10-10T00:00'
{{ c.page.meta.labels }} -> 'Label1'
{{ c.page.meta.get('labels') }} -> 'Label1'
{{ c.page.meta.get_list('labels') }} -> ['Label1', 'Label2']
{{ c.page.meta.show_comments }} -> true
{{ c.page.meta.not_exist }} -> None

page.labels returns list of Label objects connected to the page:

{% for label in c.page.labels %}{{ label.title }}{% end %}

Label object has next attributes:

• title

• slug

c.pages returns an iterable that allows to get all pages list. In label.html it return only pages belong to the label. You also can get any page by uri using c.pages.

{% for page in c.pages %}{{ page.title }}{% end %}

{{ c.pages['2010/09/blog-post'].html }}

{{ c.pages.for_label('default') }}

Running the server

To run the application use site/engine/app.py:

import os.path

from c2p2 import app
from c2p2.settings import settings


rel = lambda p: os.path.join(os.path.dirname(os.path.realpath(__file__)), p)


if __name__ == '__main__':
    settings.SOURCE_FOLDER = rel('..')
    app.run()

Run locally

cd site
virtualenv venv --no-site-packages -p /usr/local/bin/python3.5
source venv/bin/activate
pip install c2p2
python engine/app.py

Open http://localhost:5000 in browser.

Update site if md file was changed without server restart (watch md files)

Use UPDATE_TIMEOUT setting.

Update site on GitHub push

Create a new GitHub hook for your repository:

• url: http://mysite.com/pull

• secret: should be equal to GITHUB_SECRET setting value

Production configuration

Example settings:

• DEBUG=false

• UPDATE_TIMEOUT=0

• GITHUB_VALIDATE_IP=true

• GITHUB_SECRET=<webhook secret>

• GITHUB_BRANCH=master

Example supervisor configuration:

[program:mysite]
process_name=mysite
directory=/home/deploy/mysite
environment=C2P2_PORT=5100,C2P2_DEBUG=false,C2P2_UPDATE_TIMEOUT=0,C2P2_GITHUB_VALIDATE_ID=true,C2P2_GIHUB_SECRET=123xyz,C2P2_GITHUB_BRANCH=master
command=/home/deploy/mysite/venv/bin/python engine/app.py
user=deploy
stdout_logfile=/var/log/mysite/out.log
stderr_logfile=/var/log/mysite/err.log
autostart=true
autorestart=true

Example nginx configuration:

upstream mysite {
    server 127.0.0.1:5100;
}

server {
    listen   80;

    # If you need to restrict access
    # auth_basic "Restricted";
    # auth_basic_user_file /etc/nginx/.htpasswd;

    server_name mysite.com;

    location / {
        proxy_cache off;
        proxy_pass http://mysite;
    }

    location ~* \.(?:css|png|jpe?g|gif|ico|zip|txt)$ {
        root /home/deploy/mysite;
        log_not_found off;
    }

    error_page 500 502 503 504 /home/deploy/mysite/engine/templates/500.html;
    error_page 400 402 403 404 /home/deploy/mysite/engine/templates/400.html;
}

Favicon and robots.txt

Just add favicon.ico and robots.txt to root folder of your site.
