start

docker-compose up --build -d

develop

The /bot folder is mounted into the container, so you just need to restart to get your updated changes.

docker-compose build
docker-compose up # ctrl-c to stop and run up again to restart

linting

This codebase uses the PEP 8 code style. We enforce this with isort, black & flake8. In addition to the standards outlined in PEP 8, we have a few guidelines (see setup.cfg for more info):

First build the tester Docker image

$ make build

Format the code with black & isort

$ make fixme

To check if it is formatted properly, run:

$ make check

A git pre-commit hook for automatically linting before comitting can be found in git-hook, to install it:

$ cp git-hook .git/hooks/pre-commit

How to Use

The main use for fiskebot is to easily set up a CTF for your discord server to play as a team. The following commands listed are probably going to be used the most.

• !help Display the main help commands.

• !create "ctf name" This is the command you'll use when you want to begin a new CTF. This command will make a text channel with your supplied name. The bot will also send a message in chat where members can react to join the CTF.

• !add <challenge name> This will create a new channel for a given challenge.

• !done [@users ...] Mark a challenge as done. Needs to be done inside the challenge channel. Optionally specify other users who also contributed to solving the challenge, space separated without the @s.

• !ctf archive Mark the ctf as over and move it to the archive categories (specified in /bot/config.py).

---

The following commands use the api from ctftime

• !ctftime countdown/timeleft Countdown will return when a selected CTF starts, and timeleft will return when any currently running CTFs end in the form of days hours minutes and seconds.

• !ctftime upcoming <number> Uses the api mentioned to return an embed up to 5 upcoming CTFs. If no number is provided the default is 3.

• !ctftime current Displays any currently running CTFs in the same embed as previously mentioned.

• !ctftime top <year> Shows the ctftime leaderboards from a certain year (dates back to 2011).

• !ctftime team [team name/id] Display the top 10 events a team have gotten points for this year.
