# Description
`htmlescape` is unmaintained: https://crates.io/crates/htmlescape
while `v_htmlescape` is: https://crates.io/crates/v_htmlescape
and is used by two popular crates (`actix-files` and `minijinja`)
Let's use this instead - I'm packaging `nu` in Fedora and there is
understandable reluctance in bringing in an unmaintained crate if we can
avoid it.
# User-Facing Changes
Should not be any; drop-in replacement
# Tests + Formatting
Tested using:
- `cargo build` in the root folder (needed by some `nu-command` tests)
- `cargo test --features sqlite` in `crates/nu-command`
(`tests/commands/database/into_sqlite.rs` needs `rusqlite`)
- `cargo test` in `crates/nu-cmd-extra`

# Description
Hi,
This closes#10446 , wherein we start implementing `mv` from `uutils`.
There are some stuff to iron out, particularly
* Decide on behavior from ignored tests
* Wait for release/PRs to be approved on `uutils` side, but still can be
tested for now. See [PR
approved](https://github.com/uutils/coreutils/pull/5428), and
[pending](https://github.com/uutils/coreutils/pull/5429).
* `--progress` does not seem to work on `uutils mv` either and have not
checked whether certain `X` size has to be achieved in order for it to
appear, thus something to investigate as well, but thought it wasnt
important enough to not make the PR.
See [issue
comment](https://github.com/nushell/nushell/issues/10446#issuecomment-1764497988),
on the possible strategy to follow, mainly copy what we did with `ucp`.
I still left some comments on purpose particularly on tests, which of
course would be removed before something is decided here. :) @fdncred

# Description
Currently, the `into sqlite` command collects the entire input stream
into a single Value, which soaks up the entire input into memory, before
it ever tries to write anything to the DB. This is very problematic for
large inputs; for example, I tried transforming a multi-gigabyte CSV
file into SQLite, and before I knew what was happening, my system's
memory was completely exhausted, and I had to hard reboot to recover.
This PR fixes this problem by working directly with the pipeline stream,
inserting into the DB as values are read from the stream.
In order to facilitate working with the stream directly, I introduced a
new `Table` struct to store the connection and a few configuration
parameters, as well as to make it easier to lazily create the table on
the first read value.
In addition to the purely functional fixes, a few other changes were
made to the serialization and user facing behavior.
### Serialization
Much of the preexisting code was focused on generating the exact text
needed for a SQL statement. This is unneeded and less safe than using
the `rusqlite` crate's serialization for native Rust types along with
prepared statements.
### User-Facing Changes
Currently, the command is very liberal in the input types it accepts.
The strategy is basically if it is a record, try to follow its structure
and make an analogous SQL row, which is pretty reasonable. However, when
it's not a record, it basically tries to guess what the user wanted and
just makes a single column table and serializes the value into that one
column, whatever type it may be.
This has been changed so that it only accepts records as input. If the
user wants to serialize non-record types into SQL, then they must
explicitly opt into doing this by constructing a record or table with it
first. For a utility for inserting data into SQL, I think it makes more
sense to let the user choose how to convert their data, rather than make
a choice for them that may surprise them.
However, I understand this may be a controversial change. If the
maintainers don't agree, I can change this back.
#### Long switch names
The `file_name` and `table_name` long form switches are currently
snake_case and expect to be as such at the command line. These have been
changed to kebab-case to be more conventional.
# Tests + Formatting
To test the memory consumption, I used [this publicly available index of
all Wikipedia articles](https://dumps.wikimedia.org/enwiki/20230820/),
using the first 10,000, 100,000, and 1,000,000 entries, in that order. I
ran the following script to benchmark the changes against the current
stable release:
```nu
#!/usr/bin/nu
# let shellbin = $"($env.HOME)/src/nushell/target/aarch64-linux-android/release/nu"
let shellbin = "nu"
const dbpath = 'enwiki-index.db'
[10000, 100000, 1000000]
| each {|rows|
rm -f $dbpath;
do { time -f '%M %e %U %S' $shellbin -c (
$"bzip2 -cdk ~/enwiki-20230820-pages-articles-multistream-index.txt.bz2
| head -n ($rows)
| lines
| parse '{offset}:{id}:{title}'
| update cells -c [offset, id] { into int }
| into sqlite ($dbpath)"
)
}
| complete
| get stderr
| str trim
| parse '{rss_max} {real} {user} {kernel}'
| update cells -c [rss_max] { $"($in)kb" | into filesize }
| update cells -c [real, user, kernel] { $"($in)sec" | into duration }
| insert rows $rows
| roll right
}
| flatten
| to nuon
```
This yields the following results
Current stable release:
|rows|rss_max|real|user|kernel|
|-|-|-|-|-|
|10000|53.6 MiB|770ms|460ms|420ms|

# Note
I started this branch kind of at the same time as my others, but I
understand the feedback that smaller PRs are preferred. Let me know if
it would be better to split this up.
I do think the scope of the changes are on the bigger side even without
the behavior changes I mentioned, so I'm not sure if that will help this
particular PR very much, but I'm happy to oblige on request.

Fix the breaking changes.
Get's rid of some outdated transitive dependencies.
Sadly we need to expose more of `procfs` to `nu-command` based on how
the features of `nu-system` are exposed right now.
Conditional compilation/dependencies from hell included
Supersedes #11101
closes#10845
I've opened this a little prematurely to get some questions answered
before I cleanup the code.
As I started trying to better understand GNUs `mktemp` I've realized its
kind of peculiar and we might want to change its behavior to introduce
it to nushell.
#### quiet and dry run
Does it make sense to keep the `quiet` and `dry_run` flags? I don't
think so. The GNU documentation says this about the dry run flag "Using
the output of this command to create a new file is inherently unsafe, as
there is a window of time between generating the name and using it where
another process can create an object by the same name." So yeah why keep
it? As far as quiet goes, does it make sense to silence the errors in
nushell?
#### other confusing flags
According to the [gnu
docs](https://www.gnu.org/software/coreutils/manual/html_node/mktemp-invocation.html),
the `-t` flag is deprecated and the `-p`/ `--tempdir` are the same flag
with the only difference being `--tempdir` takes an optional path, Given
that, I've broken the `-p` away from `--tempdir`. Now there is one
switch `--tmpdir`/`-t` and one named param `--tmpdir-path`/`-p`.
GNU mktemp
```
-p DIR, --tmpdir[=DIR] interpret TEMPLATE relative to DIR; if DIR is not
specified, use $TMPDIR if set, else /tmp. With
this option, TEMPLATE must not be an absolute name;
unlike with -t, TEMPLATE may contain slashes, but
mktemp creates only the final component
-t interpret TEMPLATE as a single file name component,
relative to a directory: $TMPDIR, if set; else the
directory specified via -p; else /tmp [deprecated]
```
to
nushell mktemp
```
-p, --tmpdir-path <Filepath> # named param, must provide a path
-t, --tmpdir # a switch
```
Is this a terrible idea?
What should I do?

Implements `whoami` using the `whoami` command from uutils as backend.
This is a draft because it depends on
https://github.com/uutils/coreutils/pull/5310 and a new release of
uutils needs to be made (and the paths in `Cargo.toml` should be
updated). At this point, this is more of a proof of concept 😄
Additionally, this implements a (simple and naive) conversion from the
uutils `UResult` to the nushell `ShellError`, which should help with the
integration of other utils, too. I can split that off into a separate PR
if desired.
I put this command in the "platform" category. If it should go somewhere
else, let me know!
The tests will currently fail, because I've used a local path to uutils.
Once the PR on the uutils side is merged, I'll update it to a git path
so that it can be tested and runs on more machines than just mine.

New `whoami` command. This might break some users who expect the system
`whoami` command. However, the result of this new command should be very
close, just with a nicer help message, at least for Linux users. The
default `whoami` on Windows is quite different from this implementation:

Reverts nushell/nushell#10812
This goes back to a version of `regex` and its dependencies that is
shared with a lot of our other dependencies. Before this we did not
duplicate big dependencies of `regex` that affect binary size and
compile time.
As there is no known bug or security problem we suffer from, we can wait
on receiving the performance improvements to `regex` with the rest of
our `regex` dependents.
r? @fdncred
Last one, I hope. At least short of completely redesigning `registry
query`'s interface. (Which I wouldn't implement without asking around
first.)
# Description
User-Facing Changes has the general overview. Inline comments provide a
lot of justification on specific choices. Most of the type conversions
should be reasonably noncontroversial, but expanding `REG_EXPAND_SZ`
needs some justification. First, an example of the behavior there:
```shell
> # release nushell:
> version | select version commit_hash | to md --pretty
| version | commit_hash |
| ------- | ---------------------------------------- |
| 0.85.0 | a6f62e05ae |
> registry query --hkcu Environment TEMP | get value
%USERPROFILE%\AppData\Local\Temp
> # with this patch:
> version | select version commit_hash | to md --pretty
| version | commit_hash |
| ------- | ---------------------------------------- |
| 0.86.1 | 0c5a4c991f |
> registry query --hkcu Environment TEMP | get value
C:\Users\CAD\AppData\Local\Temp
> # Microsoft CLI tooling behavior:
> ^pwsh -c `(Get-ItemProperty HKCU:\Environment).TEMP`
C:\Users\CAD\AppData\Local\Temp
> ^reg query HKCU\Environment /v TEMP
HKEY_CURRENT_USER\Environment
TEMP REG_EXPAND_SZ %USERPROFILE%\AppData\Local\Temp
```
As noted in the inline comments, I'm arguing that it makes more sense to
eagerly expand the %EnvironmentString% placeholders, as none of
Nushell's path functionality will interpret these placeholders. This
makes the behavior of `registry query` match the behavior of pwsh's
`Get-ItemProperty` registry access, and means that paths (the most
common use of `REG_EXPAND_SZ`) are actually usable.
This does *not* break nu_script's
[`update-path`](https://github.com/nushell/nu_scripts/blob/main/sourced/update-path.nu);
it will just be slightly inefficient as it will not find any
`%Placeholder%`s to manually expand anymore. But also, note that
`update-path` is currently *wrong*, as a path including
`%LocalAppData%Low` is perfectly valid and sometimes used (to go to
`Appdata\LocalLow`); expansion isn't done solely on a path segment
basis, as is implemented by `update-path`.
I believe that the type conversions implemented by this patch are
essentially always desired. But if we want to keep `registry query`
"pure", we could easily introduce a `registry get`[^get] which does the
more complete interpretation of registry types, and leave `registry
query` alone as doing the bare minimum. Or we could teach `path expand`
to do `ExpandEnvironmentStringsW`. But REG_EXPAND_SZ being the odd one
out of not getting its registry type semantics decoded by `registry
query` seems wrong.
[^get]: This is the potential redesign I alluded to at the top. One
potential change could be to make `registry get Environment` produce
`record<Path: string, TEMP: string, TMP: string>` instead of `registry
query`'s `table<name: string, value: string, type: string>`, the idea
being to make it feel as native as possible. We could even translate
between Nu's cell-path and registry paths -- cell paths with spaces do
actually work, if a bit awkwardly -- or even introduce lazy records so
the registry can be traversed with normal data manipulation ... but that
all seems a bit much.
# User-Facing Changes
- `registry query`'s produced `value` has changed. Specifically:
- ❗ Rows `where type == REG_EXPAND_SZ` now expand `%EnvironmentVarable%`
placeholders for you. For example, `registry query --hkcu Environment
TEMP | get value` returns `C:\Users\CAD\AppData\Local\Temp` instead of
`%USERPROFILE%\AppData\Local\Temp`.
- You can restore the old behavior and preserve the placeholders by
passing a new `--no-expand` switch.
- Rows `where type == REG_MULTI_SZ` now provide a `list<string>` value.
They previously had that same list, but `| str join "\n"`.
- Rows `where type == REG_DWORD_BIG_ENDIAN` now provide the correct
numeric value instead of a byte-swapped value.
- Rows `where type == REG_QWORD` now provide the correct numeric
value[^sign] instead of the value modulo 2<sup>32</sup>.
- Rows `where type == REG_LINK` now provide a string value of the link
target registry path instead of an internal debug string representation.
(This should never be visible, as links should be transparently
followed.)
- Rows `where type =~ RESOURCE` now provide a binary value instead of an
internal debug string representation.
[^sign]: Nu's `int` is a signed 64-bit integer. As such, values >=
2<sup>63</sup> will be reported as their negative two's compliment
value. This might sometimes be the correct interpretation -- the
registry does not distinguish between signed and unsigned integer values
-- but regedit and pwsh display all values as unsigned.
# Description
This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.
In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.
# User-Facing Changes
This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.
update: here's an example of the error you'll see:

# Description
This new command `into value` is a command that tries to infer the type
of data you have in a table. It converts each cell to a string and then
runs a set of regular expressions on that string. This was mostly
cobbled together after looking at how polars does similar things. The
regular expressions were taken straight form polars and tweaked.
### Before
```nushell
❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] |
update col1 {|r| $r.col1 | into int } |
update col3 {|r| $r.col3 | into float } |
update col4 {|r| $r.col4 | into bool } |
update col5 {|r| $r.col5 | into datetime } |
update col6 {|r| $r.col6 | into datetime }
╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮
│0│ 1│two │3.40│true│a month ago│8 hours ago│
╰─┴────┴────┴────┴────┴───────────┴───────────╯
```
or
```nushell
❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] |
into int col1 |
into float col3 |
into bool col4 |
into datetime col5 col6
╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮
│0│ 1│two │3.40│true│a month ago│8 hours ago│
╰─┴────┴────┴────┴────┴───────────┴───────────╯
```
### After
```nushell
❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] | into value
╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮

╰─┴────┴────┴────┴────┴───────────┴───────────╯
```
It's definitely not perfect. There are ways it will fail because on
regular expressions not working on all formats. My hope is that people
will pick this up and add more regular expressions and if there are
problems with the existing ones, change them. This is meant as a
"starter command" with easy entry for newcomers that are looking to chip
in and help out.
Also, some tests probably need to be added to ensure what we have now
doesn't break with updates.
