This is a set of thingies to run our Monarch-Of-The-Hill contest,
which in the past has been called
"Tracer FIRE",
"Project 2",
"HACK",
"Queen Of The Hill",
"Cyber Spark",
"Cyber Fire",
"Cyber Fire Puzzles",
and "Cyber Fire Foundry".

Information about these events is at
http://dirtbags.net/contest/

This software serves up puzzles in a manner similar to Jeopardy.
It also tracks scores,
and comes with a JavaScript-based scoreboard to display team rankings.


Running a Development Server
============================

To use example puzzles

    docker run --rm -it -p 8080:8080 dirtbags/moth-devel

or, to use your own puzzles

    docker run --rm -it -p 8080:8080 -v /path/to/puzzles:/puzzles:ro dirtbags/moth-devel

And point a browser to http://localhost:8080/ (or whatever host is running the server).

The development server includes a number of Python libraries that we have found useful in writing puzzles.

When you're ready to create your own puzzles,
read [the devel server documentation](doc/devel-server.md).

Click the `[mb]` link by a puzzle category to compile and download a mothball that the production server can read.


Running a Production Server
===========================

    docker run --rm -it -p 8080:8080 -v /path/to/moth/state:/state -v /path/to/moth/balls:/mothballs:ro dirtbags/moth

You can be more fine-grained about directories, if you like.
Inside the container, you need the following paths:

* `/state` (rw) Where state is stored. Read [the overview](doc/overview.md) to learn what's what in here.
* `/mothballs` (ro) Mothballs (puzzle bundles) as provided by the development server.
* `/resources` (ro) Overrides for built-in HTML/CSS resources.





Getting Started Developing
-------------------------------

If you don't have a `puzzles` directory,
you can copy the example puzzles as a starting point:

    $ cp -r example-puzzles puzzles

Then launch the development server:

    $ python3 devel/devel-server.py

Point a web browser at http://localhost:8080/
and start hacking on things in your `puzzles` directory.

More on how the devel sever works in
[the devel server documentation](doc/devel-server.md)


Running A Production Server
====================

Run `dirtbags/moth` (Docker) or `mothd` (native).

`mothd` assumes you're running a contest out of `/moth`.
For Docker, you'll need to bind-mount your actual directories
(`state`, `mothballs`, and optionally `resources`) into
`/moth/`.

You can override any path with an option,
run `mothd -help` for usage.


State Directory
===============


Pausing scoring
-------------------

Create the file `state/disabled`
to pause scoring,
and remove it to resume.
You can use the Unix `touch` command to create the file:

    touch state/disabled

When scoring is paused,
participants can still submit answers,
and the system will tell them whether the answer is correct.
As soon as you unpause,
all correctly-submitted answers will be scored.


Resetting an instance
-------------------

Remove the file `state/initialized`,
and the server will zap everything.


Setting up custom team IDs
-------------------

The file `state/teamids.txt` has all the team IDs,
one per line.
This defaults to all 4-digit natural numbers.
You can edit it to be whatever strings you like.

We sometimes to set `teamids.txt` to a bunch of random 8-digit hex values:

    for i in $(seq 50); do od -x /dev/urandom | awk '{print $2 $3; exit;}'; done

Remember that team IDs are essentially passwords.


Enabling offline/PWA mode
-------------------

If the file `state/export_manifest` is found, the server will expose the 
endpoint `/current_manifest.json?id=<teamId>`. This endpoint will return 
a list of all files, including static theme content and JSON and content 
for currently-unlocked puzzles. This is used by the native PWA 
implementation and `Cache` button on the index page to cache all of the 
content necessary to display currently-open puzzles while offline. 
Grading will be unavailable while offline. Some puzzles may not function 
as expected while offline. A valid team ID must be provided.

Mothball Directory
==================

Installing puzzle categories
-------------------

The development server will provide you with a `.mb` (mothball) file,
when you click the `[mb]` link next to a category.

Just drop that file into the `mothballs` directory,
and the server will pick it up.

If you remove a mothball,
the category will vanish,
but points scored in that category won't!
