What version of ripgrep are you using?

ripgrep 0.8.1

What operating system are you using ripgrep on?

macOS High Sierra

Bug

This command detects multiple -v params:

$ rg -ve foo -ve bar /dev/null
error: The argument '--invert-match' was provided more than once, but cannot be used multiple times

This doesn't:

$ rg -ve foo -v -e bar /dev/null

Also this one:

$ rg -v -e foo --invert-match --invert-match -e bar /dev/null

I'm not sure what should be the expected behaviour, but I think it's not consistent.

This looks like a clap bug. The expected behavior is for multiple -v flags to be allowed, but it looks like you found a case where clap doesn't permit it, even though AppSettings::AllArgsOverrideSelf is set.

Thanks for the ping! I'll look into it soon, it appears that it'll be a super easy fix.

@kbknapp Should I create an issue on clap's repo for this or does one already exist?

ripgrep began it's life with docopt for argument parsing. Then it moved
to Clap and stayed there for a number of years. Clap has served ripgrep
well, and it probably could continue to serve ripgrep well, but I ended
up deciding to move off of it.

Why?

The first time I had the thought of moving off of Clap was during the
2->3->4 transition. I thought the 3.x and 4.x releases were great, but
for me, it ended up moving a little too quickly. Since the release of
4.x was telegraphed around when 3.x came out, I decided to just hold off
and wait to migrate to 4.x instead of doing a 3.x migration followed
shortly by another 4.x migration. Of course, I just never ended up doing
the migration at all. I never got around to it and there just wasn't a
compelling reason for me to upgrade. While I never investigated it, I
saw an upgrade as a non-trivial amount of work in part because I didn't
encapsulate the usage of Clap enough.

The above is just what got me started thinking about it. It wasn't
enough to get me to move off of it on its own. What ended up pushing me
over the edge was a combination of factors:

* As mentioned above, I didn't want to run on the migration treadmill.
This has proven to not be much of an issue, but at the time of the
2->3->4 releases, I didn't know how long Clap 4.x would be out before a
5.x would come out.
* The release of lexopt[1] caught my eye. IMO, that crate demonstrates
exactly how something new can arrive on the scene and just thoroughly
solve a problem minimalistically. It has the docs, the reasoning, the
simple API, the tests and good judgment. It gets all the weird corner
cases right that Clap also gets right (and is part of why I was
originally attracted to Clap).
* I have an overall desire to reduce the size of my dependency tree. In
part because a smaller dependency tree tends to correlate with better
compile times, but also in part because it reduces my reliance and trust
on others. It lets me be the "master" of ripgrep's destiny by reducing
the amount of behavior that is the result of someone else's decision
(whether good or bad).
* I perceived that Clap solves a more general problem than what I
actually need solved. Despite the vast number of flags that ripgrep has,
its requirements are actually pretty simple. We just need simple
switches and flags that support one value. No multi-value flags. No
sub-commands. And probably a lot of other functionality that Clap has
that makes it so flexible for so many different use cases. (I'm being
hand wavy on the last point.)

With all that said, perhaps most importantly, the future of ripgrep
possibly demands a more flexible CLI argument parser. In today's world,
I would really like, for example, flags like `--type` and `--type-not`
to be able to accumulate their repeated values into a single sequence
while respecting the order they appear on the CLI. For example, prior
to this migration, `rg regex-automata -Tlock -ttoml` would not return
results in `Cargo.lock` in this repository because the `-Tlock` always
took priority even though `-ttoml` appeared after it. But with this
migration, `-ttoml` now correctly overrides `-Tlock`. We would like to
do similar things for `-g/--glob` and `--iglob` and potentially even
now introduce a `-G/--glob-not` flag instead of requiring users to use
`!` to negate a glob. (Which I had done originally to work-around this
problem.) And some day, I'd like to add some kind of boolean matching to
ripgrep perhaps similar to how `git grep` does it. (Although I haven't
thought too carefully on a design yet.) In order to do that, I perceive
it would be difficult to implement correctly in Clap.

I believe that this last point is possible to implement correctly in
Clap 2.x, although it is awkward to do so. I have not looked closely
enough at the Clap 4.x API to know whether it's still possible there. In
any case, these were enough reasons to move off of Clap and own more of
the argument parsing process myself.

This did require a few things:

* I had to write my own logic for how arguments are combined into one
single state object. Of course, I wanted this. This was part of the
upside. But it's still code I didn't have to write for Clap.
* I had to write my own shell completion generator.
* I had to write my own `-h/--help` output generator.
* I also had to write my own man page generator. Well, I had to do this
with Clap 2.x too, although my understanding is that Clap 4.x supports
this. With that said, without having tried it, my guess is that I
probably wouldn't have liked the output it generated because I
ultimately had to write most of the roff by hand myself to get the man
page I wanted. (This also had the benefit of dropping the build
dependency on asciidoc/asciidoctor.)

While this is definitely a fair bit of extra work, it overall only cost
me a couple days. IMO, that's a good trade off given that this code is
unlikely to change again in any substantial way. And it should also
allow for more flexible semantics going forward.

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this issue Nov 28, 2023
14.0.2 (2023-11-27)
===================
This is a patch release with a few small bug fixes.

Bug fixes:

* [BUG #2654](BurntSushi/ripgrep#2654):
  Fix `deb` release sha256 sum file.
* [BUG #2658](BurntSushi/ripgrep#2658):
  Fix partial regression in the behavior of `--null-data --line-regexp`.
* [BUG #2659](BurntSushi/ripgrep#2659):
  Fix Fish shell completions.
* [BUG #2662](BurntSushi/ripgrep#2662):
  Fix typo in documentation for `-i/--ignore-case`.


14.0.1 (2023-11-26)
===================
This a patch release meant to fix `cargo install ripgrep` on Windows.

Bug fixes:

* [BUG #2653](BurntSushi/ripgrep#2653):
  Include `pkg/windows/Manifest.xml` in crate package.


14.0.0 (2023-11-26)
===================
ripgrep 14 is a new major version release of ripgrep that has some new
features, performance improvements and a lot of bug fixes.

The headlining feature in this release is hyperlink support. In this release,
they are an opt-in feature but may change to an opt-out feature in the future.
To enable them, try passing `--hyperlink-format default`. If you use [VS Code],
then try passing `--hyperlink-format vscode`. Please [report your experience
with hyperlinks][report-hyperlinks], positive or negative.

[VS Code]: https://code.visualstudio.com/
[report-hyperlinks]: BurntSushi/ripgrep#2611

Another headlining development in this release is that it contains a rewrite
of its regex engine. You generally shouldn't notice any changes, except for
some searches may get faster. You can read more about the [regex engine rewrite
on my blog][regex-internals]. Please [report your performance improvements or
regressions that you notice][report-perf].

[report-perf]: BurntSushi/ripgrep#2652

Finally, ripgrep switched the library it uses for argument parsing. Users
should not notice a difference in most cases (error messages have changed
somewhat), but flag overrides should generally be more consistent. For example,
things like `--no-ignore --ignore-vcs` work as one would expect (disables all
filtering related to ignore rules except for rules found in version control
systems such as `git`).

[regex-internals]: https://blog.burntsushi.net/regex-internals/

**BREAKING CHANGES**:

* `rg -C1 -A2` used to be equivalent to `rg -A2`, but now it is equivalent to
  `rg -B1 -A2`. That is, `-A` and `-B` no longer completely override `-C`.
  Instead, they only partially override `-C`.

Build process changes:

* ripgrep's shell completions and man page are now created by running ripgrep
with a new `--generate` flag. For example, `rg --generate man` will write a
man page in `roff` format on stdout. The release archives have not changed.
* The optional build dependency on `asciidoc` or `asciidoctor` has been
dropped. Previously, it was used to produce ripgrep's man page. ripgrep now
owns this process itself by writing `roff` directly.

Performance improvements:

* [PERF #1746](BurntSushi/ripgrep#1746):
  Make some cases with inner literals faster.
* [PERF #1760](BurntSushi/ripgrep#1760):
  Make most searches with `\b` look-arounds (among others) much faster.
* [PERF #2591](BurntSushi/ripgrep#2591):
  Parallel directory traversal now uses work stealing for faster searches.
* [PERF #2642](BurntSushi/ripgrep#2642):
  Parallel directory traversal has some contention reduced.

Feature enhancements:

* Added or improved file type filtering for Ada, DITA, Elixir, Fuchsia, Gentoo,
  Gradle, GraphQL, Markdown, Prolog, Raku, TypeScript, USD, V
* [FEATURE #665](BurntSushi/ripgrep#665):
  Add a new `--hyperlink-format` flag that turns file paths into hyperlinks.
* [FEATURE #1709](BurntSushi/ripgrep#1709):
  Improve documentation of ripgrep's behavior when stdout is a tty.
* [FEATURE #1737](BurntSushi/ripgrep#1737):
  Provide binaries for Apple silicon.
* [FEATURE #1790](BurntSushi/ripgrep#1790):
  Add new `--stop-on-nonmatch` flag.
* [FEATURE #1814](BurntSushi/ripgrep#1814):
  Flags are now categorized in `-h/--help` output and ripgrep's man page.
* [FEATURE #1838](BurntSushi/ripgrep#1838):
  An error is shown when searching for NUL bytes with binary detection enabled.
* [FEATURE #2195](BurntSushi/ripgrep#2195):
  When `extra-verbose` mode is enabled in zsh, show extra file type info.
* [FEATURE #2298](BurntSushi/ripgrep#2298):
  Add instructions for installing ripgrep using `cargo binstall`.
* [FEATURE #2409](BurntSushi/ripgrep#2409):
  Added installation instructions for `winget`.
* [FEATURE #2425](BurntSushi/ripgrep#2425):
  Shell completions (and man page) can be created via `rg --generate`.
* [FEATURE #2524](BurntSushi/ripgrep#2524):
  The `--debug` flag now indicates whether stdin or `./` is being searched.
* [FEATURE #2643](BurntSushi/ripgrep#2643):
  Make `-d` a short flag for `--max-depth`.
* [FEATURE #2645](BurntSushi/ripgrep#2645):
  The `--version` output will now also contain PCRE2 availability information.

* [BUG #884](BurntSushi/ripgrep#884):
  Don't error when `-v/--invert-match` is used multiple times.
* [BUG #1275](BurntSushi/ripgrep#1275):
  Fix bug with `\b` assertion in the regex engine.
* [BUG #1376](BurntSushi/ripgrep#1376):
