This commit adds a --completion-bash option to node which can be sourced to
provide bash code completion for node options.

Usage:

$ node --completion-bash > node_bash_completion
$ source node_bash_completion
$ ./node --[tab]  # (press the 'tab' key)
--abort_on_uncaught_exception  --inspect-brk-node=            --require

I know some UNIX CLI tools ship something like tool --completion baked into the executable, which provides a source-able bash script as the output. Would that make sense?

Sorry about the delay on this. Just to clarify, your suggestion is that we provide an option to node which returns the source-able bash script? Something like:

$ node --completion

How robust is this? That is how much can we change the output of node --help before this breaks?

Perhaps @addaleax suggestion about #22490 (which I've not looked into yet) might help making this more robust. I'll take a closer look next week.

I'm tending toward -0 on this, as is. Since the real "magic" is baked into the --help logic, this seems like a too specific change for a specific target (IIUC just bash), that could be replaced with a simple independant snippet:

_node_complete()
{
  local cur_word options
  cur_word="${COMP_WORDS[COMP_CWORD]}"
  options="`$1 --help`"
  if [[ "${cur_word}" == -* ]] ; then
    COMPREPLY=( $(compgen -W '${options}' -- "${cur_word}") )
    return 0
  else
    COMPREPLY=( $(compgen -f "${cur_word}") )
    return 0
  fi
}
complete -F _node_complete node node_g

src/node.cc Outdated
" return 0\n"
" fi\n"
"}\n"
"complete -F _node_complete node node_g\n");

Notable changes:

* assert
  * The diff output is now a tiny bit improved by sorting object
    properties when inspecting the values that are compared with each
    other. #22788
* cli
  * The options parser now normalizes `_` to `-` in all multi-word
    command-line flags, e.g. `--no_warnings` has the same effect as
    `--no-warnings`. #23020
  * Added bash completion for the `node` binary. To generate a bash
    completion script, run `node --completion-bash`. The output can be
    saved to a file which can be sourced to enable completion.
    #20713
* crypto
  * Added support for PEM-level encryption.
    #23151
  * Added an API asymmetric key pair generation. The new methods
    `crypto.generateKeyPair` and `crypto.generateKeyPairSync` can be
    used to generate public and private key pairs. The API supports
    RSA, DSA and EC and a variety of key encodings (both PEM and DER).
    #22660
* fs
  * Added a `recursive` option to `fs.mkdir` and `fs.mkdirSync`. If
    this option is set to true, non-existing parent folders will be
    automatically created. #21875
* http2
  * Added a `'ping'` event to `Http2Session` that is emitted whenever a
    non-ack `PING` is received.
    #23009
  * Added support for the `ORIGIN` frame.
    #22956
  * Updated nghttp2 to 1.34.0. This adds RFC 8441 extended connect
    protocol support to allow use of WebSockets over HTTP/2.
    #23284
* module
  * Added `module.createRequireFromPath(filename)`. This new method can
    be used to create a custom require function that will resolve
    modules relative to the filename path.
    #19360
* process
  * Added a `'multipleResolves'` process event that is emitted whenever
    a `Promise` is attempted to be resolved multiple times, e.g. if the
    `resolve` and `reject` functions are both called in a `Promise`
    executor. #22218
* url
  * Added `url.fileURLToPath(url)` and `url.pathToFileURL(path)`. These
    methods can be used to correctly convert between file: URLs and
    absolute paths. #22506
* util
  * Added the `sorted` option to `util.inspect()`. If set to `true`,
    all properties of an object and Set and Map entries will be sorted
    in the returned string. If set to a function, it is used as a
    compare function. #22788
  * The `util.instpect.custom` symbol is now defined in the global
    symbol registry as `Symbol.for('nodejs.util.inspect.custom')`.
    #20857
  * Added support for `BigInt` numbers in `util.format()`.
    #22097
* V8 API
  * A number of V8 C++ APIs have been marked as deprecated since they
    have been removed in the upstream repository. Replacement APIs
    are added where necessary. #23159
* Windows
  * The Windows msi installer now provides an option to automatically
    install the tools required to build native modules.
    #22645
* Workers
  * Debugging support for Workers using the DevTools protocol has been
    implemented. #21364
  * The public `inspector` module is now enabled in Workers.
    #22769
