GLV-1.12556: The First Gemini Protocol Server It's named after the NASA designation for Gemini 1, which is fitting, because it's the first Gemini protocol server written. Features: * Serves any type of document * Configurable filenames for default Gemini index files * Configurable extension for Gemini index files * Will create a Gemini index file for directories sans a Gemini index file * Support for CGI * Gemini-specific CGI scripts * HTTP-specific CGI scripts * Support for user directories * Authentication by client certificates * Easily extensible with support for custom handlers * Configuration via file Prerequisites: * Lua 5.3 * LibreSSL 2.5.0 or higher * GNU libmagic (NOTE: This is NOT image manipulation, but file identification) * A whole bunch of Lua modules, availble at: * https://github.com/spc476/lua-conmanorg * https://github.com/spc476/LPeg-Parsers Installation: This will require some work. You will need to download the modules listed above from Github and get them installed. The lua-conmanorg repository will take some futzing around to get it compiled (first hint: remove any mention of tcc in the Makefile). But once you have all the prerequisites installed, the server should just work. Bulding: Just type "make" (there's one C module that might be required, depending upon your desired configuration). If you have the Lua include files in a non-standard location, you may need to do: make LUA_INCDIR=/path/to/Lua/includes You can do "make install" if you want to install the server onto the system: make install This will install files in the following locations: /usr/local/bin/GLV-1.12556 # server /usr/local/lib/lua/5.3/GLV-1 # server modules (written in C) /usr/local/share/lua/5.3/GLV-1 # server modules (written in Lua) To fine tune, you can from the command line: make [location] install The various [location] options are (multiple can be specified) predix=taget-dir target-dir/bin/GLV-1.12556 target-dir/lib/lua/5.3/GLV-1 target-dir/share/lua/5.3/GLV-1 LUADIR=target-dir target-dir/GLV-1 # modules written in Lua LIBDIR=target-dir target-dir/GLV-1 # modules written in C BINDIR=target-dir target-dir/GLV-1.12556 # server program If the Lua include files are in a non-standard location, you can specify: make LUA_INCDIR=/path/to/lua/includes But you do not need to install anything if you run GLV-1.12556.lua directly in the Lua subdirectory. The program requires a single argument, the location of the configuration file. Configuration: You will need to generate a certificate, as the protocol requires the use of TLS. There are plenty of on-line tortorials about generating a self-signed certificate, or you could use a certificate from Let's Encrypt. The file "minimal-conf.lua" is the bare minimum configuration file you'll need to serve up files from a directory, but do look at the sample-conf.lua file as that has extensive comments about each section and what is required, and what isn't. It will help to know some Lua, especially Lua string patterns (its form of regex) as various sections of the configuration are applied to requests via pattern matching of the request. To run CGI scripts, you'll need to include the cgi section in the configuration file, After that, any file that the filesystem handler encounters that is marked executable will be treated as a CGI script and run. If CGI is NOT enable, the server will simply return a temporary error (and log the condition via syslog()). Miscellaneous: The handlers under GLV-1.handlers.non-std are in use with my server and require additional files and configuration than mentioned here. You can use these to see how handlers are written, but these are specialized for the content on my server at <gemini://gemini.conman.org/>.
