ts-node -i repl do not fflush stdout

[wsdjeg]

hello, and thanks for working for this project, and I just want to add typescript repl support in SpaceVim

the code runner works well now, but the repl do not work in my plugin, as the ts-node -i do not fflush the sdtout buffer until we send (os/exit).

@wsdjeg Can you briefly describe what you're trying to do? The REPL is written to stdout here:

ts-node/src/bin.ts

Lines 407 to 408 in 2a0f1f3

	if (name) repl.outputStream.write(`${name}\n`)
	if (comment) repl.outputStream.write(`${comment}\n`)

(it's initialized here:

ts-node/src/bin.ts

Lines 343 to 345 in 2a0f1f3

	input: process.stdin,
	output: process.stdout,
	terminal: process.stdout.isTTY,

). There might be some options to tweak here.

what is terminal: process.stdout.isTTY,? I do not use ts-node in terminal but in pipe.

@wsdjeg it's an option passed to repl.start, explained here: https://nodejs.org/docs/latest-v13.x/api/repl.html#repl_repl_start_options

EDIT disregard this comment, I think I'm wrong about this. (previous comment is still accurate)

@wsdjeg This should be fixed by #1019, which has been released in v8.9.1

Thank you for the bug report!
