Re: "How does Gemini differ from the Nex protocol? I see Nex..."

In: s/Gemini

I would describe Nex as a stripped-down Gopher. Comparing to Gemini:

Plain TCP sockets, no TLS (i.e., no certificates or encryption of any kind).
Client requests a path → server sends just the file contents or a directory listing. No URLs, response headers, status codes, or MIME types are involved.
Directory listings use a plain text format with `=> ` link lines. Whitespace is not normalized so you can fancily preformat the page as you want. There is no word wrapping, which makes things simpler, but it can be a bit awkward on small screens.

Nex also can support a cgi-like page though without input parameters I guess, this is not currently available, but the author is planing to support some kind of page generation or has already implemented that. Also there is an option to provide input data but that is not in the nex protocol but uses an additional socket connect, there is an example of that on the nightfall.city site

otherwise the protocol reminds me of HTTP/0.9 which did not use headers yet, so there was no content-type

Thanks for the comments everyone. Since it doesn’t use TLS, I should probably have asked how it compares to Spartan, although then this wouldn’t be the right forum for that.

The hidden file .directory-listing-okay in Gemini does what I need as far as directory listings are concerned. So based on my understanding now, Nex would have to have a very simple server executable for me to justify running it.

That said, nightfall does have a gorgeous looking Nex page. The links to the files and directories are often followed by a comment. In Gemini, a link would be replaced with such text rather than complimented.

How does Gemini differ from the Nex protocol? I see Nex used for directory listings and serving files. Gemini seems to do this and much more. Is it as simple as that?
