⚔️ golt

golt is a CLI-based third-party game launcher for OldSchool Runescape.

Why?

The official recommendation points to several community projects, most of which involve running the launcher in Wine or a similar environment. However, I really wanted a native solution, or one that didn't require installing a 1.5GB compatibility layer solely for launcher functionality.

While there is a project that served as the inspiration for this one, and functions seamlessly on Linux, there were some boxes that it didn't tick for me:

  • Its installation size is ~460MB
  • Lack of support for overriding the client launch command/environment
  • It's a bit of a pain to compile

In comparison, the linux-amd64 build for golt is a single 6.8MB binary.

Installation

Either download the latest binary from the Releases page (or build it yourself), and add it to a directory on your PATH.

Then, create a desktop entry for this application:

[Desktop Entry]
Type=Application
Name=golt
Exec=golt %U
StartupNotify=true
Terminal=true
MimeType=x-scheme-handler/jagex;
Categories=Game;
Name[en_US]=golt

Place it under /usr/share/applications/golt.desktop

Then, register it to be the default handler for the jagex:<...> scheme:

xdg-mime default golt.desktop x-scheme-handler/jagex

And reload the MIME-types database:

update-desktop-database

Finally, set up an iptable entry to redirect localhost:80 to localhost:8080:

sudo iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 80 -j REDIRECT --to-ports 8080
Why?

The login flow is currently done in the browser:

  • The OAuth login redirects to a page which invokes a scheme handler
  • The game login step redirects to http://localhost

These redirect URLs are validated server side, so cannot be modified on the client side.

As for the iptable entry, most Linux distros don't allow binding to port 80, so golt binds to port 8080 instead.

Configuration

Environment VariableDefaultDescription
GOLT_GAME_PATHRuneLite.AppImageEither a binary on PATH, or an absolute path to the client to launch.
This value is passed to exec.Command(docs)
GOLT_BIND_PORT8080Local port to which golt will bind to to receive the OAuth response callback.
If this is not 80, you must set up an iptable entry to redirect inbound traffic from port 80 to this port.

As for the iptable entry, most Linux distros don't allow binding to port 80, so golt binds to port 8080 instead.
Configuration
Environment VariableDefaultDescription
GOLT_GAME_PATHRuneLite.AppImageEither a binary on PATH, or an absolute path to the client to launch.
This value is passed to exec.Command(docs)
GOLT_BIND_PORT8080Local port to which golt will bind to to receive the OAuth response callback.
If this is not 80, you must set up an iptable entry to redirect inbound traffic from port 80 to this port.

⚔️ golt
golt is a CLI-based third-party game launcher for OldSchool Runescape.
Why?
The official recommendation
points to several community projects, most of which involve running the launcher in Wine or a similar environment.
However, I really wanted a native solution, or one
that didn't require installing a 1.5GB compatibility layer solely for launcher functionality.
While there is a project that served as the inspiration for this one, and functions seamlessly on Linux, there were some
boxes that it didn't tick for me:
  • Its installation size is ~460MB
  • Lack of support for overriding the client launch command/environment
  • It's a bit of a pain to compile
In comparison, the linux-amd64 build for golt is a single 6.8MB binary.
Installation
Either download the latest binary from the Releases page (or build it
yourself), and add it to a directory on your PATH.
Then, create a desktop entry for this application:
[Desktop Entry]
Type=Application
Name=golt
Exec=golt %U
StartupNotify=true
Terminal=true
MimeType=x-scheme-handler/jagex;
Categories=Game;
Name[en_US]=golt

Place it under /usr/share/applications/golt.desktop
Then, register it to be the default handler for the jagex:<...> scheme:
xdg-mime default golt.desktop x-scheme-handler/jagex
And reload the MIME-types database:
update-desktop-database
Finally, set up an iptable entry to redirect localhost:80 to localhost:8080:
sudo iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 80 -j REDIRECT --to-ports 8080
Why?
The login flow is currently done in the browser:
  • The OAuth login redirects to a page which invokes a scheme handler
  • The game login step redirects to http://localhost
These redirect URLs are validated server side, so cannot be modified on the client side.
As for the iptable entry, most Linux distros don't allow binding to port 80, so golt binds to port 8080 instead.
