The Tannhauser Gate

A proof-of-concept script to allow content in geminispace to be accessed from any gopher browser.

gopher://tannhauser.ulthar.xyz

M$ Github doesn't hyperlink gopher urls, so here's a floodgap link

Dependencies

• nmap, for ncat
• geomyidae

Known Bugs

• Content-type handler is screwy. The case statement always defaults, even when the content-type is text/gemini.
• Path and URL handling parsing is brittle. The parsing logic in tannhauser.dcgi and the creation logic in gmi2gph.awk work about 90% of the time, but fail for relative links in the current directory and links to parent directories.

TODO

• We don't support any kind of Gemini user input yet.
• Pass the torture test.
• Figure out a portable way to removing nmap as a dependency.
• Make this script server-agnostic.
• Wrap lines at 72 columns.
• Make sure there aren't any code-injection vulnerabilities (^_^;).
