Anarki: a publicly modifiable 'wiki-like' fork of PG's and RTM's Arc Lisp (http://www.paulgraham.com/arc.html)
The intention is to be extremely permissive in accepting patches. For commit privileges, just submit your first pull request or ask on http://arclanguage.org/forum.
Important: If you are already running a HN-like site, migrating to this fork might mess up your site's data. Come talk to us first, and be sure to make a backup before the migration.
Anarki is explicitly not constrained to maintain compatibility with pg's releases, and compatibility status may swing wildly from commit to commit depending on who takes an interest.
To run, install Racket from http://racket-lang.org, then:
$ git clone http://github.com/arclanguage/anarki $ cd anarki $ ./arc # interactive repl arc> :a $
Anarki has thorough automated tests. To run them, install mercurial, then:
# start in the anarki directory $ hg clone https://bitbucket.org/zck/unit-test.arc $ ./arc arc> (load "tests.arc")
To run the HN server, first pick your (the admin's) username:
$ mkdir www $ echo __username__ > www/admins
(You can have multiple admins. Add them all to www/admins, separated by whitespace.)
Now bring up the server:
There'll be a pause while the server loads up, with some messages, then you'll see the 'arc> ' prompt.
Go to http://localhost:8080. Click on login, and create the account for your username. You should now be logged in as an admin.
Don't worry about "user break" or "error writing" messages.
To customize News, change the variables at the top of lib/news.arc. To change the port your server runs at, modify lib/run-news.
Any interactive changes to the prompt will be reflected immediately in the server, without needing to restart it. Don't forget to add them to the .arc files as appropriate, otherwise they'll be lost when you stop the server or it dies for some reason.
