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) {
^
TypeError: Cannot call method 'trim' of undefined

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.
