# Description
This PR adds an alternative alias implementation. Old aliases still work
but you need to use `old-alias` instead of `alias`.
Instead of replacing spans in the original code and re-parsing, which
proved to be extremely error-prone and a constant source of panics, the
new implementation creates a new command that references the old
command. Consider the new alias defined as `alias ll = ls -l`. The
parser creates a new command called `ll` and remembers that it is
actually a `ls` command called with the `-l` flag. Then, when the parser
sees the `ll` command, it will translate it to `ls -l` and passes to it
any parameters that were passed to the call to `ll`. It works quite
similar to how known externals defined with `extern` are implemented.
The new alias implementation should work the same way as the old
aliases, including exporting from modules, referencing both known and
unknown externals. It seems to preserve custom completions and pipeline
metadata. It is quite robust in most cases but there are some rough
edges (see later).

No effect: https://github.com/nushell/nushell/issues/8122 (we might
revisit the completions code after this PR)
Should use custom command instead:

# User-Facing Changes
Since aliases are now basically commands, it has some new implications:
1. `alias spam = "spam"` (requires command call)
* **workaround**: use `alias spam = echo "spam"`
2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than
once)
* **workaround**: use different name (commands also have this
limitation)
4. `alias ls = (ls | sort-by type name -i)`
* **workaround**: Use custom command. _The common issue with this is
that it is currently not easy to pass flags through custom commands and
command referencing itself will lead to stack overflow. Both of these
issues are meant to be addressed._
5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc.
* Should we treat the aliases as commands or should they be separated
from regular commands?
6. Needs better error message and syntax highlight for recursed alias
(`alias f = f`)
7. Can't create alias with the same name as existing command (`alias ls
= ls -a`)
* Might be possible to add support for it (not 100% sure)
8. Standalone `alias` doesn't list aliases anymore
9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay
use` won't work)
* TODO: Needs a better error message when attempting to do so

# Description
issue #8167
Remove the `(link)` to the docs for `ShellError` and `ParseError`. As
per discussion on the issue, the nu-parser version didn't update on the
docs causing deadlinks for those errors, which brought the usefullness
of these links into question and it was decided to remove all of them
that `derive(diagnostic)`.

This does two fixes for bare words:
* It changes completions for paths to wrap a path with backticks if it
starts with a number. This helps bare words that start with numbers be
separate from unit values
* It allows bare words wrapped with backticks to be the name of a
command. Backtick values in command positions are no longer treated as
strings

# Description
From nushell 0.8 philosophy:
https://github.com/nushell/nushell.github.io/blob/main/contributor-book/philosophy_0_80.md#core-categories
> The following categories should be moved to plugins:
Uncommon format support
So this pr is trying to move following commands to plugin:
- [X] from eml
- [x] from ics
- [x] from ini
- [x] from vcf
And we can have a new plugin handles for these formatting, currently
it's implemented here:
https://github.com/WindSoilder/nu_plugin_format
The command usage should be the same to original command.
If it's ok, the plugin can support more formats like
[parquet](https://github.com/fdncred/nu_plugin_from_parquet), or [EDN
format](https://github.com/nushell/nushell/issues/6415), or something
else.
Just create a draft pr to show what's the blueprint looks like, and is
it a good direction to move forward?

I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give
better error messages. Similarly for `assert!(a != b)` and
`assert_ne!(a, b)`. Basically all instances were comparing primitives
(string slices or integers), so there is no loss of generality from
special-case macros,
I have also fixed a number of typos in comments, variable names, and a
few user-facing messages.

(almost all of which were in test code) have been changed to `null`.
Now, the only place that refers to `$nothing` is the parser code which

Reverts nushell/nushell#7448
Some surprising behavior in how we do this. For example:
```
〉if (true || false) { print "yes!" } else { print "no!" }
no!
〉if (true or false) { print "yes!" } else { print "no!" }
yes!
```
This means for folks who are using the old `||`, they possibly get the
wrong answer once they upgrade. I don't think we can ship with that as
it will catch too many people by surprise and just make it easier to
write buggy code.
# Description
We got some feedback from folks used to other shells that `try/catch`
isn't quite as convenient as things like `||`. This PR adds `&&` as a
synonym for `;` and `||` as equivalent to what `try/catch` would do.

# Description
This PR is a response to the issues raised in
https://github.com/nushell/nushell/pull/7087. It consists of two
changes:
* `export-env`, when evaluated in `overlay use`, will see the original
environment. Previously, it would see the environment from previous
overlay activation.
* Added a new `--reload` flag that reloads the overlay. Custom
definitions will be kept but the original definitions and environment
will be reloaded.
This enables a pattern when an overlay is supposed to shadow an existing
environment variable, such as `PROMPT_COMMAND`, but `overlay use` would
keep loading the value from the first activation. You can easily test it
by defining a module
```
module prompt {
export-env {
let-env PROMPT_COMMAND = (date now | into string)
}
}
```
Calling `overlay use prompt` for the first time changes the prompt to
the current time, however, subsequent calls of `overlay use` won't
change the time. That's because overlays, once activated, store their
state so they can be hidden and restored at later time. To force-reload
the environment, use the new flag: Calling `overlay use --reload prompt`
repeatedly now updates the prompt with the current time each time.
# User-Facing Changes
* When calling `overlay use`, if the module has an `export-env` block,
the block will see the environment as it is _before_ the overlay is
activated. Previously, it was _after_.
* A new `overlay use --reload` flag.

# Description
As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.
And if the command is executed directly like: `cat tmp`, the result
won't change.
Fixes: #6816Fixes: #3980
Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.
If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

This reverts commit 959d14203e.
* Change `str collect` help message to say that it is deprecated
We cannot remove `str collect` currently (i.e. via
`nu_protocol::ShellError::DeprecatedCommand` since a prominent project
uses the API:
b85542c31c/src/virtualenv/activation/nushell/activate.nu (L43)
Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency.
- More understandable for newcomers, that these commands are no special to others.
- `?` syntax did not really aprove readability. For me it made it worse.
- We can reserve `?` syntax for any other nushell feature.
