A Clojure CLI to the REPtiLe server to expose a shared PREPL

The CLI depends on the the server lib reptile-lib - a server that can be started in various contexts for example the dev env or the CLI.

I have a sister UI project reptile-tongue - a browser based client for REPtiLe.

In this mode, a PREPL socket server will be started as in process.

The command takes these run time parameters: http-port - a number above 1024, on which the web server will be exposed shared-secret - to hand out to clients so that they can connect

$ clojure -A:reptile 8888 warm-blooded-lizards-rock

In this mode, another process is running a PREPL socket server and REPtiLe will connect to it.

The command takes these run time parameters: http-port - a number above 1024, on which the web server will be exposed shared-secret - to hand out to clients so that they can connect

socket-host - the host which is running the socket server socket-port - port number for socket server

$ clojure -A:reptile 8888 warm-blooded-lizards-rock localhost 9075

An example of an application that can be used as the other process in this mode is the add-lib-demo-app

The first version will be considered feature complete once the server provides

• Shared REPL state
• Shared view of edits in real-time
• Shared REPL history
• Authentication using shared secret
• Dynamic addition of new libraries to the REPL
• Documentation to explain client / server hosting options
• Limit user count (2, 3, 4, etc...)
• Limit users based on user names (jane, joe, mary, etc...)

After the initial version these additional features are planned

• Incremental feedback on long running REPL evaluations
• Cancel long running REPL evaluations
• Choice of Java / node runtime REPLs
• Investigate GraalVM
