Minimal but usable interactive Gemini client in < 100 LOC of Lua.
|
|
|
|
Depends upon:
|
|
|
|
* [LuaSocket](http://w3.impa.br/~diego/software/luasocket/)
|
|
* [LuaSec](https://github.com/brunoos/luasec)
|
|
* [Microlight](https://stevedonovan.github.io/microlight/)
|
|
|
|
## Rationale
|
|
|
|
One of the original design criteria for the Gemini protocol was that
|
|
"a basic but usable (not ultra-spartan) client should fit comfortably
|
|
within 50 or so lines of code in a modern high-level language.
|
|
Certainly not more than 100". This client was written to gauge how
|
|
close to (or far from!) that goal the initial rough specification is.
|
|
|
|
## Capabilities
|
|
|
|
This crude but functional client:
|
|
|
|
* Has a minimal interactive interface for "Gemini maps"
|
|
* Will print plain text in any encoding if it is properly declared in
|
|
the server's response header
|
|
* Will follow redirects
|
|
* Will report errors
|
|
* Does NOT DO ANY validation of TLS certificates
|
|
|
|
Non-text files are not yet handled.
|
|
|
|
It's a *snug* fit in 100 lines, but it's possible. A 50 LOC client
|
|
would need to be much simpler.
|
|
|
|
## Usage
|
|
|
|
Run the script and you'll get a prompt. Type a Gemini URL (the scheme
|
|
is implied, so simply entering e.g. `gemini.conman.org` will work) to
|
|
visit a Gemini location.
|
|
|
|
If a Gemini menu is visited, you'll see numeric indices for links, ala
|
|
VF-1 or AV-98. Type a number to visit that link.
|
|
|
|
There is very crude history: you can type `b` to go "back".
|
|
|
|
Type `q` to quit.
