# Serene (Simple) version
|
|
**Serene simple** is a lisp that is implemented in Java as a proof of concept and as an experience
|
|
to collect data on some of the ideas and implementations that I have. For the full story checkout
|
|
my [blog](https://lxsameer.com/).
|
|
|
|
## Requirements
|
|
* JDK >= 1.8
|
|
* rlwrap
|
|
* gradle
|
|
|
|
## Repl
|
|
in order to run the REPL, run `make repl`
|
|
|
|
## nRepl
|
|
Use `make nrepl` command to fire up a nRepl process and connect to it using `netcat` or something
|
|
similar. If you're using Emacs, there is a `serene-mode` available that distributes as part of
|
|
[FG42](https://gitlab.com/FG42/FG42/blob/master/lib/extensions/serene/serene-simple-mode.el).
|
|
|
|
Serene's nRepl is super simple. It waits for a newline char and then evaluates the
|
|
given input. It sends back the result of the evaluation in `<status-char><value>` format.
|
|
`status-char` is either `0` or `1`. **Zero** means the evaluation was successful and the `value`
|
|
is the result of evaluation while **one** means there was an error during the evaluation and
|
|
the `value` is the traceback for the exception.
