`roman` is written in [Nim](https://nim-lang.org). Binaries are not yet available, so you will need to build from source. With `nim 0.20` installed, you should simply need to run `nimble build`. 

`roman` uses [`html2text`](http://alir3z4.github.io/html2text/) to display post bodies. You will need to have it installed on your system. [`nim-html2text`](https://git.sr.ht/~reesmichael1/nim-html2text) is being actively developed to replace this dependency.

## Usage

To subscribe to feeds, use the `subscribe` command. For example,

`roman` is still in very early development. [Several improvements are planned!](https://todo.sr.ht/~reesmichael1/roman) However, `roman` is already quite usable.

### Renderers

By default, `roman` uses [`html2text`](http://alir3z4.github.io/html2text/) to display post bodies. You will need to have it installed on your system. 

However, if `roman` is compiled with `-d:internalRenderer`, the experimental [`nim-html2text`](https://git.sr.ht/~reesmichael1/nim-html2text) library will be used instead. This library still needs work, but it removes the need for an external dependency.

## Configuration

You will need to copy the `config/config` file in this repository to `roman/config` within your platform's standard config directory. You can change the values in the file to your taste.
