# PyWebServer # Amethyst Web Server
## GitHub ## A word of warning!
The upstream of this project is on my own [Gitea instance](https://git.novacow.ch/Nova/PyWebServer/). Currently Amethyst is in very early alpha stage, a lot of things will be broken, names won't be correct,
Because of that I'll mostly reply to issues and PRs there, you can submit issues and PRs on GitHub, but it might take longer before I read it. promised features missing, but I'm very much working on it live!
Every save I do increments the build number by 1, I won't publish all of them, but most of them will be published.
Once a milestone is hit (e.g. a new feature fully implemented), I'll publish a release!
## Installing ## Currently working features:
Installing and running PyWebServer is very simple. * New configuration is ~75% done, most features work.
Assuming you're running Linux: * Fixed **A LOT** of unreported bugs from the old code.
```bash * More resilliency against errors.
git clone https://git.novacow.ch/Nova/PyWebServer.git * Improved security.
cd ./PyWebServer/
```
Windows users, make sure you have installed Git, from there:
```powershell
git clone https://git.novacow.ch/Nova/PyWebServer.git
Set-Location .\PyWebServer\
```
Then, open `pywebsrv.conf` in your favorite text editor and change the `directory` key to the full path where your files are stored.
After that, put your files in and run this:
Linux:
```bash
python3 /path/to/pywebsrv.py
```
Windows:
```powershell
# If you have installed Python via the Microsoft Store:
python3 \path\to\pywebsrv.py
# Via the python.org website:
py \path\to\pywebsrv.py
```
## SSL Support ## Project status:
PyWebServer supports SSL/TLS for authentication via HTTPS. In the config file, you should enable the HTTPS port. After that you need to create the certificate. Amethyst will stay in beta for a while, I want all features to work, put I will make pre-release versions that are mostly stable.
Currently PyWebServer looks for the `cert.pem` and the `key.pem` files in the root directory of the installation. They can be found as the `amethyst-prerel-0.a.b` releases. I won't guarantee 100% stability, but waay more than just some random build.
## HTTP support ## Install instructions:
Currently PyWebServer only supports HTTP/1.1, this is very unlikely to change, as most of the modern web today still uses HTTP/1.1. Install Python, and change the provided config.
For methods PyWebServer only supports `GET`, this is being reworked though, check issue [#3](https://git.novacow.ch/Nova/PyWebServer/issues/3) for progress.
## Files support ## Minimum requirements:
Unlike other small web servers, PyWebServer has full support for binary files being sent and received (once that logic is put in) over HTTP(S). Python 3.8+
And whatever PC that happens to run that.
I recommend Python 3.10 or above though, with a PC running:
* Windows 8.1+
* macOS 10.15+
* Linux 4.19+
* FreeBSD 13.2R+
* Some other somewhat recent OS.
## Support ## Currently W.I.P. Check back later!
PyWebServer will follow a standard support scheme.
### 1.x
For every 1.x version there will be support until 2 newer versions come out.
So that means that 1.0 will still be supported when 1.1 comes out, but no longer be supported when 1.2 comes out.
### 2.x
I am planning on releasing a 2.x version with will have a lot more advanced features, like nginx's server block emulation amongst other things.
When 2.0 will come out, the last version of 1.x will be supported for a while longer, but no new features will be added.
