This should only be minimally used, since the `terminal` value will usually be
what you are expecting. This option is specifically for the case where `terminal`
is false, but you still want colors to be output (or vice-versa).
Previously this was a module-level setting, meaning that all REPL instances
had to share the same writer function. Turning it into one of the options
allows individual REPL instances to use their own writer function.
The overall goal here is to make readline more interoperable with other node
Streams like say a net.Socket instance, in "terminal" mode.
See #2922 for all the details.
Closes #2922.

Bugfix and update.
- Fixed bug where Node's REPL wouldn't continue when returning from ^Z
(SIGTSTP)
- Removed old readline callback
Readline API update with docs.
- ^Z (SIGTSTP) is now bypassed on Windows systems.
- SIGCONT is now bypassed on Windows systems.
- Docs updated to reflect above.
Repl is doing double evaluation of code: wrapped in parens and without
them. That's needed to allow users typing multiline chunks of code by
handling syntax errors on repl side. However if function declaration is
wrapped in parens (`(function a() {})`) calling it will be impossible,
so we're evaluating functions twice. That works fine for declaration,
but if entered code chunk returns function - it should not be called
twice.
fix #2773
- Removed extra newline from .question(); Users can input a
newline if it they require it.
- Removed .close() due to it only emulating closing, causing a bug where
readline is left open to trigger events such as .on('line', ...').
- Removed ._attemptClose()
- .pause() now triggers event .on('pause', ...)
- .resume() now triggers event .on('resume', ...)
- CTRL-C (SIGINT) in readline will now default to .pause() if no SIGINT event
is present.
- CTRL-D (delete right) will also default to .pause() if there is nothing to
delete (signaling the end of the file).
- Added new event `SIGTSTP`
- Added new event `SIGCONT`
- Added `resume` to `write` to resume the stream if paused.
- Docs updated.
- Updated repl.js
Fixes #2063.
REPLServer.prototype.resetContext:
Reset the line cache
REPLServer.prototype.memory (don't know if I like that name, called from finish)
pushes what cmd's have been executed against it into this.lines
pushes the "tab depth" for bufferedCommands, in this.lines.level
REPLServer.prototype.displayPrompt:
Uses "tab depth" from this.lines.level to adjust the prompt to visually
denote this depth e.g.
> asdf = function () {
… var inner = {
….. one:1
REPLServer.prototype.complete:
Now notices if there is a bufferedCommand and attempts determine locally
scoped variables by removing any functions from this.lines and evaling these
lines in a nested REPL e.g.
> asdf = function () {
… var inner = { one: 1};
… inn\t
will complete to 'inner' and inner.o\t will complete to 'inner.one'
If the nested REPL still has a bufferedCommand it will falls back to the
default.
ArrayStream is a helper class for the nested REPL to get commands pushed to it.
new REPLServer('', new ArrayStream());
Finally added two new REPL commands .save and .load, each takes 1 parameter,
a file and attempts to save or load the file to or from the REPL
respectively.

It's been a while now, and we've seen how this separate context thing
works. It constantly confuses people, and no one actually uses '.clear'
anyway, so the benefit of that feature does not justify the constant
WTFery.
This makes repl.context actually be a getter that returns the global
object, and prints a deprecation warning. The '.clear' command is gone,
and will report that it's an invalid repl keyword. Tests updated to
allow the require, module, and exports globals, which are still
available in the repl just like they were before, by making them global.
* Don't buffer command, before it's execution (repl)
* `quit` command, custom streams for .start, stubbed out test, disable
history repeation for non-tty (debugger)
