GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
# GNU AFFERO GENERAL PUBLIC LICENSE
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Version 3, 19 November 2007
Preamble
Copyright (C) 2007 Free Software Foundation, Inc.
<https://fsf.org/>
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
## Preamble
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains
free software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
@ -26,65 +27,56 @@ them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing
under this license.
The precise terms and conditions for copying, distribution and
modification follow.

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for
the specific requirements.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".

## 🧪 Installation
### Download and install dependencies
Clone the repo
```sh
git clone https://git.waifuism.life/waifu/kemoverse.git
cd kemoverse
```
Setup a virtual environment (Optional, recommended)
```sh
python3 -m venv venv
source venv/bin/activate
```
Install project dependencies via pip
```sh
python3 -m pip install -r requirements.txt
```
### Setup config file
A sample config file is included with the project as a template: `example_config.ini`
Create a copy of this file and replace its' values with your own. Consult the
template for more information about individual config values and their meaning.
Config files are environment-specific. Use `config_dev.ini` for development and
`config_prod.ini` for production. Switch between environments using the
`KEMOVERSE_ENV` environment variable.
```sh
cp example_config.ini config_dev.ini
# Edit config_dev.ini
```
### Setup database
To set up the database, run:
```sh
KEMOVERSE_ENV=dev python3 setup_db.py
```
### Run the bot
```sh
KEMOVERSE_ENV=dev ./startup.sh
```
If all goes well, you should now be able to interact with the bot.
### Running in production
To run the the in a production environment, use `KEMOVERSE_ENV=prod`. You will
also need to create a `config_prod.ini` file and run the database setup step
again if pointing prod to a different database. (you are pointing dev and prod
to different databases, right? 🤨)
### Updating
To update the bot, first pull new changes from upstream:
```sh
git pull
```
Then run any database migrations. We recommend testing in dev beforehand to
make sure nothing breaks in the update process.
**Always backup your prod database before running any migrations!**
```sh
# Backup database file
cp gacha_game_dev.db gacha_game_dev.db.bak
# Run migrations
KEMOVERSE_ENV=dev python3 setup_db.py
```

<h1>About This Gacha</h1>
<p>This is a playful Misskey-themed gacha tracker made with Flask and SQLite.</p>
<p>All rolls are stored, stats are tracked, and characters are added manually for now.</p>
<p>Built with love, chaos, and way too much caffeine ☕.</p>
