# Charred Gold

This is a fork of [Charred Black](https://github.com/modality/charred-black) Below is a partial fork of the original README of Charred Black; especially since there is a departure from some of the original values.  The unofficial, online, Burning Wheel Gold (+Codex) character burner. Adapted from [Charred](https://charred.herokuapp.com/). Later adapted from [Charred Black](https://github.com/modality/charred-black)

## Project Structure

* `Dockerfile` and `Dockerfile.dev` - Container definition files. The dev container has automated reloading if you mount the container's filesystem to the host machine. These mostly serve as examples to launch the app yourself, and are no longer supported. The app uses Sinatra to hope, and you should just be able to `bundle install` and then run `ruby app.rb` from the source directory. I will try to publish a SysV initscript soon.
* `src/data` - Binaries and data files for lifepaths live here, see `dark_elf` and `wizard` directory for well-defined examples
* `src/lib` - Ruby scripts for caching, PDF generation, and data loading
* `src/public` - Javascript and CSS
* `src/views` - HTML templates
* `src/app.rb` - The webapp, uses Sinatra

## Beliefs

We welcome community contributions, and you are welcome to fork this source code if you want to go your own way. As the maintainer, here's what you can expect from me when I judge contributions.

### Do One Thing Well

Charred Gold is a character creation utility. You are welcome to use the data, source code, or character files in the creation of other gaming tools, but let's keep this tool focused on one thing and do it really well.

### Stick To Published Material

In order to keep the scope of my maintainership finite, I'm not planning to accept community-made lifepaths et al. for inclusion in this codebase. Each additional data set increases Charred Gold's startup time and memory requirements. The design of your lifepath requirements and emotional attributes may not be supported by the editor, or may be convoluted to implement. Most importantly, deciding to include any community-made content makes me an arbiter of quality, and I'd prefer not to have the Enmity Clause invoked because I rejected someone's homebrew.

The current maintainers of Charred Gold are working on some tooling to allow "easy" creation of new settings, stocks, LPs, and so on. The exact method for handling has not been decided precisely.

### Keep It Mostly Stateless

Charred Gold uses an in-memory cache to allow users to upload JSON and then download .char and .pdf files. I don't know how the original Charred handled this, but the tradeoffs of this approach are:

1. Works as expected without an update to the frontend
2. PDF generation happens entirely in one process, limiting the amount of futzing you have to do with distributed systems
3. Because the cache is in memory, you can't scale processes horizontally

The cache has a limited number of keys, and only the first 16kb of data are used, with the aim of making this this app useless for nefarious purposes. The average size of a 4-lifepath character is around 4kb, so this should be more than enough. If you're trying to do something weird and your character file is bigger than this, consider using a pencil and paper.

More guidelines:

* Only JSON should be stored in the cache.
* Cached items should be invalidated upon access (by using the delete method to get the data) to restrict the usefulness of this app
  to bad actors.
* Only .pdf and .char file formats should be returned as responses when getting data out of the cache. I'll consider other formats
  on a case-by-case basis: for example, I'd be open to a format which could be used with Roll20.

## Contribution Best Practices

### Capital Case
No matter what's in the book, always use Capital Case for skills, traits, lifepaths and settings.

* Path Of Spite Subsetting
* Never A Moment Of Peace
* Ages Of The Etharch
* Reeks Of Alcohol

### Hyphens

The word after the hyphen is not capitalized.

* Rabble-rouser
* Burden Of The Crown-wise

### Lifepath Example

Some notes:
1. The best way to create new lifepaths is by following the same advice that Burning Wheel gives you: look at something similar that already exists and adapt it.
1. In the `stat` block below, you'd get both a mental and physical stat point for taking this lifpath. If you want either/or, use `[1, "pm"]`.

# Building

Requires Ruby 3.1 or better for support.

On Debian or derivatives this requires `apt-get install ruby-dev` in order to allow eventmachine to work (which is a hard dependency for thin, the webserver we're using for charred.

In order to run in normal use, simply run:

```
# sudo apt-get install ruby-dev bundler
# bundler install # on some distros this might be bundler3.1
# cd src
# HOST=0.0.0.0 PORT=7878 RACK_ENV=production ruby app.rb
```
