If an input stream would emit `end` event, like
`fs.createReadStream`, then readline need to get the last line
correctly even though that line isnt ended with `\n`.
On windows, libuv will immediately make a `ReadConsole` call (in the
thread pool) when a 'flowing' `uv_tty_t` handle is switched to
line-buffered mode. That causes an immediate issue for some users,
since libuv can't cancel the `ReadConsole` operation on Windows 8 /
Server 2012 and up if the program switches back to raw mode later.
But even if this will be fixed in libuv at some point, it's better to
avoid the overhead of starting work in the thread pool and immediately
cancelling it afther that.
See also f34f1e3, where the same change is made for the opposite
flow, e.g. move `resume()` after `_setRawMode(true)`.
Fixes#5927

Ability to return just the length of listeners for a given type, using
EventEmitter.listenerCount(emitter, event). This will be a lot cheaper
than creating a copy of the listeners array just to check its length.
Make lines ending \r\n emit one 'line' event, not two (where the second
one is an empty string).
This adds a new keypress name: 'return' (as in: 'carriage return').
Fixes#3305.
While updating the readline test cases to test both "terimal: false" and
"terminal: true" mode, it turned out that the test case testing utf8 chars
being sent over multiple write() calls was failing. The solution is to use
a string_decoder instance when parsing the "keypress" events.
Before this commit, readline was inconsistent in whether or not it would emit
"line" events with or without the trailing "\n" included. When "terminal"
mode was true, then there would be no "\n", when it was false, then the "\n"
would be present. However, the trailing "\n" doesn't add much, and most of the
time people just end up stripping it manually.
Part of #4243.
The idea here is to reduce the number of times that `setRawMode()` is called
on the `input` stream, since it is expensive, and simply pause()/resume()
should not call it.
So now `setRawMode()` only gets called at the beginning of the Interface
instance, and then when `Interface#close()` is called.
Test case included.
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.
This reverts commit 443071db57.
Patch was overly compilicated and made some incorrect assumptions about the
position of the cursor being at the bottom of the screen. @rlidwka and I are
working on getting a proper implementation written.
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.
- 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
