# uriel
Uriel Web Browser & IRC Client for TempleOS
Uriel Web Browser & (not-yet) IRC Client for TempleOS
This is a proof-of-concept web browser & (soon) IRC client for TempleOS.
This is a proof-of-concept web browser & (soon) IRC client for TempleOS.
It is still very early stages.
Start the proxy on the Host:
Add the following to your `/etc/hgbdd.conf`:
```
./uriel_proxy
modules: {
"uriel":"/path/to/uriel.py"
}
```
and bind a chardev in QEMU (or serial2 in VMware/VirtualBox) to TCP 127.0.0.1:7202
In your `HomeKeyPlugIns.HC` or other startup script:
```
#include "Uriel"
#include "HGBD";
#include "Uriel";
```
You can launch a Browser in the current Task with:
```
Browser(url);
```
Get files with:
```
Get(url or host_path, local_path);
```
or Send files with:
```
Send(local_path, host_path);
U_Browser(url);
```
# Prerequisites
- wget
- [HGBD](https://github.com/tramplersheikhs/hgbd)
- Beautiful Soup 4 (for DolDoc preprocessing)
- GraphicsMagick (for inline images)
- TOSZ (to download .Z files)
