JS/TS nREPL
Forcefully intergrating JS into the foreign realm of Clojure tooling. Both of them can evaluate code at runtime, so why not?
This is an implementation of an nREPL
server wrapping
ts-node.
Example usage with CIDER
(require 'typescript-mode)
(require 'expand-region)
(require 'js2-mode)
(defmacro my/def-ts-eval (name &rest body)
"Create a function evaluating Typescript code in CIDER.
NAME will appear at the created function's name
BODY is a snippet that marks a region of code to be evaluated in CIDER"
(declare (indent defun))
`(defun ,(intern (format "my/typescript-eval-%s" name)) ()
(interactive)
(save-mark-and-excursion
(progn
,@body
(call-interactively #'cider-eval-region)))))
(my/def-ts-eval defun (er/mark-js-function))
(my/def-ts-eval symbol (er/mark-symbol))
(my/def-ts-eval region (ignore))
(my/def-ts-eval line
(beginning-of-line)
(set-mark (point))
(end-of-line))
