@Shufei @julienxx It's alive!!! I'm really excited about the Go+Plan9 combo.I've pushed a lot of good new stuff to Molly in the past week or so (and there's more to come!), but none of it is documented yet. Hit me up if you are interested in (S)CGI.

@solderpunk so I know next to nothing about CGI. Should I just put a script that returns text in cgi-bin and molly-brown will execute it and serve the output? Do I need to handle the header in the script? @Shufei

@julienxx @Shufei More or less, yes. Define one or more CGIPaths in the config file, put your script in any subdirectory of one of those paths, make it world-executable, and Molly Brown will run it as its own process. Various details about the request (e.g. the URL the client sent) will be available as environment variables. Whatever the script writes to stdout will be send back to the client. This needs to include the response header.

@julienxx @Shufei Note that, due to limitations of Go, which will hopefully be lifted in a future release, the script is run as the same user as the server itself - which means it can do things like read/write the log file, or read the TLS private key, etc. So if you write something which accepts user input and maps that to the filesystem, be ultra careful! SCGI lets you get around this and run your scripts as `nobody`, and possibly chrooted, but it's a bit more faff to set up.

@solderpunk thanks! Plan 9 has other concepts for env, chroot... I'll have to check how everything fits

@julienxx Oh! No environment variables? I have no idea how well, if at all, CGI will work there, then.Does it have an equivalent of unix domain sockets? SCGI relies on those. Well, Molly's current implementation does. In principle you can do it over the loopback network interface too, but I haven't written anything for that yet.

@solderpunk env vars are files, as a matter of fact everything is a file in plan 9.Simple CGI (a script that calls uptime) works, now I'll try to get the vars

@solderpunk so I created a script in cgi-bin, made it executable. If I understand the code correctly here https://tildegit.org/solderpunk/molly-brown/src/branch/master/dynamic.go#L131I should have all those variables passed to my script by molly-brown?
