opaque: blogging software written in OPA

opaque is some simple blogging software written in OPA that I'm writing for projectaweek. I got an invite, so I might as well use it!

Features

  • MathJax support (uses mathjax CDN)
  • Syntax highlighting - for Haskell only at the moment (via shjs.)
  • Markdown support via upskirt.

Building

You shouldn't need anything special if you have OPA installed. Just do:

 $ make

And you have opaque.exe waiting for you.

If you want to run with opa-cloud (see below) you'll also need haproxy installed on the machine that will start the distribution and do load balancing:

 $ brew install haproxy # homebrew
 $ aptitude install haproxy # deb/ubuntu
 $ yum install haproxy # fedora
 # etc...

Supported platforms

POSIX only at the moment. You'd just need to replace the getrusage()/uname() usage inside the native binding to make it work somewhere else, really. Alas, OPA isn't available for windows yet anyway.

Running

After you've built it, you can either do:

 $ make run

Or simply:

 $ ./opaque.exe

which will start the HTTP server on port 8080 by default.

RUN IN THE CLOUD! THE CLOOOOOUUUD

Naturally your blog is so popular (due to you being awesome) that any normal server by its lonesome would never be able to handle the relentless onlslaught of crazed visitors 24/7. Let the cloud save you:

 $ make cloud CLOUD_OPTS=...

where 'CLOUD_OPTS' are the options you would normally give to opa-cloud. By default it just launches two instances on localhost. Make sure your own ssh public key is in your ~/.ssh/authorized_keys:

 $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

Admin password will be generated on the first run, and output to server debug console.

Destroying DB data

If you want to clean everything, run:

 $ make clean-db

Bugs & Misc

  • There's some weird behavior with mathjax ATM where you need to double-escape backslashes in order to use inline/block style math. So, don't use \[\alpha\], use \\[\alpha\\] and it should mostly work. Needs to be fixed.
  • The Upskirt binding is bound via OCaml. It could probably be useful in its own right, but I don't know how to get it out there (put it on GODI I guess?)
Something went wrong with that request. Please try again.
