A few improvements to du implementation: (#1533)
1. Fixed a bug where `--all` wasn't showing files at the root directories.
2. More use of `Result`'s `map` and `map_err` methods.
3. Making tables be homogeneous so one can, for example, `get directories`.

Fix poor message for executable that user doesn't have permissi… (#1535)
Previously, if the user didn't have the appropriate permissions to execute the
binary/script, they would see "command not found", which is confusing.

This commit eliminates the `which` crate in favour of `ichwh`, which deals
better with permissions by not dealing with them at all! This is closer to the
behaviour of `which` in many shells. Permission checks are then left up to the
caller to deal with.

2ddab3e8ce Some small improvements to du readability.
Mostly, making more use of `map` and `map_err` in `Result`. One benefit
is that at least one location had duplicated logic for how to map the
error, which is no longer the case after this commit.

35dc7438a5 Make use of interruptible stream in various places 2020-03-29 17:03:01 -04:00
Jason Gedge
2a54ee0c54 Introduce InterruptibleStream type.
An interruptible stream can query an `AtomicBool. If that bool is true,
the stream will no longer produce any values.

Also introducing the `Interruptible` trait, which extends any `Stream`
with the `interruptible` function, to simplify the construction and
allow chaining.

Respect CARGO_TARGET_DIR when set (#1528)
This makes the `binaries` function respect the `CARGO_TARGET_DIR` environment variable when set. If it's not present it falls back to the regular target directory used by Cargo.

Fix '/' and '..' not being valid mv targets (#1519)
* Fix '/' and '..' not being valid mv targets

If `/` or `../` is specified as the destination for `mv`, it will fail with an error message saying it's not a valid destination. This fixes it to account for the fact that `Path::file_name` return `None` when the file name evaluates to `/` or `..`. It will only take the slow(er) path if `Path::file_name` returns `None` in its initial check.

Fixes #1291

Don't emit a newline in autoview. (#1466)
The extra newline character makes it hard to use nu as part of an
external processing pipeline, since the extra character could taint the
results. For example:

```
$ nu -c 'echo test | xxd'
00000000: 7465 7374                                test
```

versus

```
nu -c 'echo test' | xxd
00000000: 7465 7374 0a                             test.

`nu-cli` will have to be rebuilt (and anything that depends on it).

Use threads to avoid blocking reads/writes in externals. (#1440)
In particular, one thing that we can't (properly) do before this commit
is consuming an infinite input stream. For example:

```
yes | grep y | head -n10
```

will give 10 "y"s in most shells, but blocks indefinitely in nu. This PR
resolves that by doing blocking I/O in threads, and reducing the `await`
calls we currently have in our pipeline code.

Update more futures-preview to futures (#1346) 2020-02-05 20:28:42 -08:00

Futures v0.3 upgrade (#1344)
* Upgrade futures, async-stream, and futures_codec

These were the last three dependencies on futures-preview. `nu` itself
is now fully dependent on `futures@0.3`, as opposed to `futures-preview`
alpha.

Because the update to `futures` from `0.3.0-alpha.19` to `0.3.0` removed
the `Stream` implementation of `VecDeque` ([changelog][changelog]), most
commands that convert a `VecDeque` to an `OutputStream` broke and had to
be fixed.

The current solution is to now convert `VecDeque`s to a `Stream` via
`futures::stream::iter`. However, it may be useful for `futures` to
create an `IntoStream` trait, implemented on the `std::collections` (or
really any `IntoIterator`). If something like this happends, it may be
worthwhile to update the trait implementations on `OutputStream` and
refactor these commands again.

While upgrading `futures_codec`, we remove a custom implementation of
`LinesCodec`, as one has been added to the library. There's also a small
refactor to make the stream output more idiomatic.

[changelog]: https://github.com/rust-lang/futures-rs/blob/master/CHANGELOG.md#030---2019-11-5

* Upgrade sys & ps plugin dependencies

They were previously dependent on `futures-preview`, and `nu_plugin_ps`
was dependent on an old version of `futures-timer`.

* Remove dependency on futures-timer from nu

* Update Cargo.lock

* Fix formatting

* Revert fmt regressions

CI is still on 1.40.0, but the latest rustfmt v1.41.0 has changes to the
`val @ pattern` syntax, causing the linting job to fail.

7efb31a4e4 Restructure and streamline token expansion (#1123)
Restructure and streamline token expansion

The purpose of this commit is to streamline the token expansion code, by
removing aspects of the code that are no longer relevant, removing
pointless duplication, and eliminating the need to pass the same
arguments to `expand_syntax`.

The first big-picture change in this commit is that instead of a handful
of `expand_` functions, which take a TokensIterator and ExpandContext, a
smaller number of methods on the `TokensIterator` do the same job.

The second big-picture change in this commit is fully eliminating the
coloring traits, making coloring a responsibility of the base expansion
implementations. This also means that the coloring tracer is merged into
the expansion tracer, so you can follow a single expansion and see how
the expansion process produced colored tokens.

One side effect of this change is that the expander itself is marginally
more error-correcting. The error correction works by switching from
structured expansion to `BackoffColoringMode` when an unexpected token
is found, which guarantees that all spans of the source are colored, but
may not be the most optimal error recovery strategy.

That said, because `BackoffColoringMode` only extends as far as a
closing delimiter (`)`, `]`, `}`) or pipe (`|`), it does result in
fairly granular correction strategy.

The current code still produces an `Err` (plus a complete list of
colored shapes) from the parsing process if any errors are encountered,
but this could easily be addressed now that the underlying expansion is
error-correcting.

This commit also colors any spans that are syntax errors in red, and
causes the parser to include some additional information about what
tokens were expected at any given point where an error was encountered,
so that completions and hinting could be more robust in the future.

* Externals now spawn independently. (#1230)

This commit changes the way we shell out externals when using the `"$it"` argument. Also pipes per row to an external's stdin if no `"$it"` argument is present for external commands. 

Further separation of logic (preparing the external's command arguments, getting the data for piping, emitting values, spawning processes) will give us a better idea for lower level details regarding external commands until we can find the right abstractions for making them more generic and unify within the pipeline calling logic of Nu internal's and external's.

* Make having --help the default
