Paperoni is a web article downloader written in Rust. The downloaded articles are then exported as EPUB files.
|
||||||
|
|
||||||
|
> This project is in an alpha release so it is pretty unstable.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```sh
|
||||||
|
paperoni https://en.wikipedia.org/wiki/Pepperoni
|
||||||
|
```
|
||||||
|
|
||||||
|
Paperoni also supports passing multiple links as arguments. If you are on a Unix-like OS, you can simply do something like this:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
cat links.txt | xargs paperoni
|
||||||
|
```
|
||||||
|
|
||||||
|
## How it works
|
||||||
|
|
||||||
|
The URL passed to Paperoni is fetched and the returned HTML response is passed to the extractor.
|
||||||
|
This extractor retrieves a possible article using a port of the [Mozilla Readability algorithm](https://github.com/mozilla/readability). This article is then saved in an EPUB.
|
||||||
|
|
||||||
|
> The port of the algorithm is still unstable as well so it is not fully compatible with all the websites that can be extracted using Readability.
|
||||||
|
|
||||||
|
## How it (currently) doesn't work
|
||||||
|
|
||||||
|
This program is still in alpha so a number of things currently break:
|
||||||
|
|
||||||
|
- Links with redirects will crash the program as it has no redirect logic.
|
||||||
|
- Websites that only run with JavaScript cannot be extracted.
|
||||||
|
- Website articles that cannot be extracted by Readability cannot be extracted by Paperoni either.
|

|
## Running locally
|
||||||
|
|
||||||
|
### Precompiled binaries
|
||||||
|
|
||||||
|
Check the [releases](https://github.com/hipstermojo/paperoni/releases) page for precompiled binaries. Currently there are only builds for Debian and Arch.
|
||||||
|
|
||||||
|
### Building from source
|
||||||
|
|
||||||
|
This project uses `async/.await` so it should be compiled using a minimum Rust version of 1.33. Preferrably use the latest version of Rust.
|
||||||
|
|
||||||
|
```sh
|
||||||
|
git clone https://github.com/hipstermojo/paperoni.git
|
||||||
|
cd paperoni
|
||||||
|
## You can build and install paperoni locally
|
||||||
|
cargo install --path .
|
||||||
|
## or use it from within the project
|
||||||
|
cargo run -- # pass your url here
|
||||||
|
```
