## Example Sites

See the [wiki](https://github.com/redline6561/coleslaw/wiki/Blogroll) for a list of coleslaw-powered blogs.

## Hacking

A core goal of *coleslaw* is to be both pleasant to read and easy to
hack on and extend. If you want to understand the internals and bend
*coleslaw* to do new and interesting things, I strongly encourage you
to read the [Hacker's Guide to Coleslaw][hackers]. You'll find some
current **TODO** items towards the bottom.

[hackers]: https://github.com/redline6561/coleslaw/blob/master/docs/hacking.md

## Installation

Coleslaw should run on any conforming Common Lisp implementation but
testing is primarily done on [SBCL](http://www.sbcl.org/) and
[CCL](http://ccl.clozure.com/).

Coleslaw can either be run **manually** on a local machine or
triggered **automatically** on git push to a server.  If you want a
server install, run these commands on your server _after_ setting up a
[git bare repo](http://git-scm.com/book/en/Git-on-the-Server-Setting-Up-the-Server).
Otherwise, run the commands on your local machine.

1. Install a Common Lisp implementation (we recommend SBCL) and
   [Quicklisp](http://quicklisp.org/).
2. Place a config file for coleslaw in your `$HOME` directory. If you
   want to run multiple blogs with coleslaw, you can keep each blog's
   config file in that blog's repo.  Feel free to copy and edit the
   [example config][ex_config] or consult the [config docs][conf_docs]
   to create one from scratch.
3. This step depends on whether you're setting up a local or server install.
   * Server Install: Copy and `chmod +x` the
     [example post-receive hook][post_hook] to your blog's bare repo.
   * Local Install:  Just run the following commands in the
     REPL whenever you're ready to regenerate your blog:
     ```
     (ql:quickload :coleslaw)
     ;; Note that the incremental plugin currently requires a "last git revision" argument.
     (coleslaw:main "/path/to/my/blog/")
     ```
4. Optionally, point the web server of your liking at your config-specified
   `:deploy-dir`. Or "deploy-dir/.curr" if the `versioned` plugin is enabled.

Now just write posts, git commit and build by hand or by push.

[conf_docs]: https://github.com/redline6561/coleslaw/blob/master/docs/config.md
[post_hook]: https://github.com/redline6561/coleslaw/blob/master/examples/example.post-receive

## The Content Format

Coleslaw expects content to have a file extension matching the class
of the content. (I.e. `.post` for blog posts, `.page` for static
pages, etc.)

There should also be a metadata header on all files
starting and ending with the config-specified `:separator`, ";;;;;" by
default. Example:

```
;;;;;
title: foo
tags: bar, baz
date: yyyy-mm-dd hh:mm:ss
format: html (for raw html) or md (for markdown)
;;;;;
your post
```

Posts require the `title:` and `format:` fields.
Pages require the `title:` and `url:` fields.

To omit a field, simply do not have the line present, empty lines and
fields (e.g. "tags:" followed by whitespace) will be ignored.

## Theming

Two themes are provided: hyde, the default, and readable (based on
[bootswatch readable](http://bootswatch.com/readable/)).
