In JS, the expression ".1" is a floating point number. Issue 4268 concerns the
REPL interpreting floating point numbers that lead with a "." as keywords. The
original bugfix worked for this specific case but not for the general case:
var x = [
.1,
.2,
.3
];
The attached change and test (`.1+.1` should be `.2`) fix the bug.
Closes#4513.
Don't give names of built-in libraries special treatment.
Changes the REPL's behavior from this:
> var path = 42
> path
A different "path" already exists globally
To this:
> var path = 42
> path
42
Fixes#4512.
Fixes#3226.
Consider a production server that uses a REPL to debug. Creating the instance
would wipe out the global cache of modules, and subsequent "require" calls in
the server would be reloaded from disk. The REPL should observe only, without
altering, its environment.
Before there was this weird module-scoped "context" variable which seemingly
shared the "context" of subsequent REPL instances, unless ".clear" was invoked
inside the REPL. To be proper, we need to ensure that each REPL gets its own
"context" object. I literally don't know why this "sharing" behavior was in place
before, but it was just plain wrong.
Wrong order of operands was causing problems while trying to use command
buffering:
> {
... a: 3,
...
repl.js:284
if (cmd.trim().match(/^npm /) && !self.bufferedCommand) {
^

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
