* Implement minmax for Range; Simplify range command
* Port random integer to enginep; New FromValue impl
Now, FromValue is implemented for Tagged<Range> to allow extracting args
into this type.
* Make sure range value extraction fails properly
The range endpoint extraction methods now return error instead of
silently clipping the value. This now makes `random integer ..-4` fail
properly since -4 can't be cast as u64.
* Port random decimal to enginep & Refactor
This added a way to interpret Range limits as f64 and a Primitive helper
to get its value as f64.
A side effect of this commit is that it is now possible to specify the
command bounds as true decimals. E.g., `random decimal 0.0..3.14` does
not clip 3.14 to 3.
* Removes arg serialization
* action stream -> output stream
* uses nu_protocol::Range instead of NumericRange
* random missing newline I found in the code
* add nu-pretty-hex, add into binary, update binaryview
* updated parameter name, updated examples
* fixed nu-pretty-hex test
* fixed tests again! and added a no color option to pretty-hex
It compiles and works without errors, but the pager is not asynchronous
anymore (i.e., you need to wait for `seq 1 1000000` to finish before the
pager is displayed).
* Add new path parse subcommand
This includes a slight refactor to all the path subcommand `action()`
functions.
* Remove filestem and extension; Fix example
* Add additional description to path parse
* Put join arg behind flag; Fix missing import (Win)
* Fix error when column path is passed as arg
* Add structured path joining
Structured path is implicitly joined at every patch subcommand call.
* Fix existing path join tests; Fix rustfmt
* Remove redundant 'static lifetime (clippy)
* Add initial impl of path split subcommand
* Add ability to join path from parts
* Fix wrong results in path split examples
* Fix remaining asyncs after engine change
* Do not wrap split path parts into table
When the input is just a list of values, the `path split` command will
split each value directly into the output stream, similar to
`split-row`. Column path--specified values are still wrapped into a
table so they can still be used to replace table fields.
* Join list of values instead of going one-by-one
When `path join` encounters a list of values, it attempts to join them,
instead of going one-by-one like the rest of the path commands. You can
still `each { echo $it | path join }` to join them one-by-one, if the
values are, e.g., tables.
Now, the behavior of `path split` and `path join` should match the
`split-row` and `str collect` counterparts and should hopefully align
better with user's expectations.
* Make sure path join detects structured path
* Fix panic on empty input stream
Also, doesn't collect input into vector unnecessarily.
* Fix path join not appending value
* Remove argument serialization
* Make better errors; Misc refactor
* OsStr -> String encoding is now lossy, instead of throwing an error
* The consequence is action() now always returns Value instead of Result
* Removed redundant handle_value() call in `path join`
* Fix possible incorrect error detection in `path split`
* Applied rustfmt + clippy
* Add more usage, examples & test; Fix type error
The 'parent' column was required to be a path but didn't work with
string.
* Add more help & examples; Maybe fix Windows error

We can check if `any` (or `all`) rows of tables match predicates.
Small `all?` example: Given the following table with `services` running:
```
> echo [[status]; [UP] [UP]]
───┬────────
# │ status
───┼────────
0 │ UP
1 │ UP
───┴────────
```
We can ask if all services are UP, like so:
```
> echo [[status]; [UP] [UP]] | all? status == UP
true
```

This reverts commit 8fc8fc89aa.
* Add tests
* Refactor .nu-env
* Change logic of Config write to logic of read()
* Fix reload always appends to old vars
* Fix reload always takes last_modified of global config
* Add reload_config in evaluation context
* Reload config after writing to it in cfg set / cfg set_into

* No let before return
* Add import for indexmap
Improvements overall to Nu. Also among the changes here, we can also be more confident towards incorporating `3041`. End to end tests for checking envs properly exported to externals is not added here (since it's in the other PR)
A few things added in this PR (probably forgetting some too)
* no writes happen to history during test runs.
* environment syncing end to end coverage added.
* clean up / refactorings few areas.
* testing API for finer control (can write tests passing more than one pipeline)
* can pass environment variables in tests that nu will inherit when running.
* No longer needed.
* no longer under a module. No need to use super.
* add support for timestamp-based time conversion by specifing timezone or 'UTC/Local'
* [fix] fix the wrong test sample
* code formating
* code formating and import missing mod to test
* code formating again
While the "main" separator in Windows is the backslash, it supports the
forward slash as a separator too.
Add support for this so that the behavior is similar to the way Windows
PowerShell handles the forward slash: it is recognized as a separator,
and when using <tab> for path completion the slash is reversed.
* Playground infraestructure (tests, etc) additions.
A few things to note:
* Nu can be started with a custom configuration file (`nu --config-file /path/to/sample_config.toml`). Useful for mocking the configuration on test runs.
* When given a custom configuration file Nu will save any changes to the file supplied appropiately.
* The `$nu.config-path` variable either shows the default configuration file (or the custom one, if given)
* We can now run end to end tests with finer grained control (currently, since this is baseline work, standard out) This will allow to check things like exit status, assert the contents with a format, etc)
* Remove (for another PR)
* Make opening a directory enter it.
Not sure if this change is wanted, but I'm not sure what else opening a directory could mean.
And I find myself accidentally using `open <dir>` to mean `enter <dir>`
* Add example to open directory
* Open dir should list it's contents
* Update example description and fix style
* update docs to refer to length instead of count
* rename count to length
* change all occurrences of 'count' to 'length' in tests
* format length command
* Move run_script to engine
* Add which dep and feature to engine
* Change unwrap to expect
* Add wasm specification
* Remove which from default, add specification correctly
* Add nu-platform-specifics
* Move is_external_cmd to platform_specifics
* Add is_external_cmd to host and use it instead of nu_platform directly
* Clean up if else logic in is_external_cmd
* Bump nu-platform-specifics version
* Pass context to print_err
* Commit cargo.lock
* Move print functions to own module inside nu-engine
* Hypocratic change to run windows-nightly again
* Add import for Ordering
* Move printing of error to host
* Move platform specific which functionality to basic host
* Allow no use of cmd_name
* Fix windows compile issue
* Split help message into brief and full help
Demonstrate on ansi command
Brief help is printed when running `help commands` so it doesn't clutter
the table. Full help is printed when normal help message is requested
(e.g., `help ansi`, `ansi --help`, etc.).
* Split long command descriptions
Some are not split, just edited to be shorter.
* Capitalize the usage of all commands
* Make sure every usage ends with dot
* Fix random typo
* use the InputHandler functionality from minus
* respond to Q and ESC character to quit
* use arijit79/minus main branch until new release is pushed
* rename NushellMinusInputHandler to MinusInputHandler
* Refactor path subcommand argument handling
DefaultArguments are no longer passed to each subcommand. Instead, each
subcommand has its own Path<xxx>Arguments. This means that it is no
longer necessary to edit every single path subcommand source file when
changing the arguments struct.
* Add new path join subcommand
Makes it easier to create new paths. It's just a wrapper around Rust's
Path.join().
* This adds table paging, relying on minus to perform the paging functionality
This is gated behind the table-pager feature
* fix problem with long running InputStreams blocking table() returning
* some comments regarding Arc clones, and callback from minus
* fix case where parent_name was {nu, term} and possibly others in the future by doing an extra test first to see if if the *parent_name key actually exists in cmap
* update with help generate_docs testing
`drop` is used for removing the last row. Passing a number allows dropping N rows.
Here we introduce the same logic for dropping columns instead.
You can certainly remove columns by using `reject`, however, there could be cases
where we are interested in removing columns from tables that contain, say, a big
number of columns. Using `reject` becomes impractical, especially when you don't
care about the column names that could either be known or not known when exploring
tables.
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]]
─────────┬───────────
lib │ extension
─────────┼───────────
nu-core │ rs
rake │ rb
─────────┴───────────
```
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]] | drop column
─────────
lib
─────────
nu-core
rake
─────────
```
There are many use cases. Here we introduce the following:
- The rows can be rolled `... | roll` (up) or `... | roll down`
- Columns can be rolled too (the default is on the `left`, you can pass `... | roll column --opposite` to roll in the other direction)
- You can `roll` the cells of a table and keeping the header names in the same order (`... | roll column --cells-only`)
- Above examples can also be passed (Ex. `... | roll down 3`) a number to tell how many places to roll.
Basic working example with rolling columns:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 0 │ 0 │ 0 │ 1 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
We want to "shift" three bits to the left of the bitstring (four in decimal), let's try it:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit4 │ bit5 │ bit6 │ bit7 │ bit8 │ bit1 │ bit2 │ bit3
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
The tables was rolled correctly (32 in decimal, for above bitstring). However, the *last three header names* look confusing.
We can roll the cell contents only to fix it.
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3 --cells-only
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
There we go. Let's compute it's decimal value now (should be 32)
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| roll column 3 --cells-only
| pivot bit --ignore-titles
| get bit
| reverse
| each --numbered { = $it.item * (2 ** $it.index) }
| math sum
32
```
The autoenv logic mutates environment variables in the running session as
it operates and decides what to do for trusted directories containing `.nu-env`
files. Few of the ways to interact with it were all in a single test function.
We separate out all the ways that were done in the single test function to document
it better. This will greatly help once we start refactoring our way out from setting
environment variables this way to just setting them to `Scope`.
This is part of an on-going effort to keep variables (`PATH` and `ENV`)
in our `Scope` and rely on it for everything related to variables.
We expect to move away from setting (`std::*`) envrironment variables in the current
running process. This is non-trivial since we need to handle cases from vars
coming in from the outside world, prioritize, and also compare to the ones
we have both stored in memory and in configuration files.
Also to send out our in-memory (in `Scope`) variables properly to external
programs once we no longer rely on `std::env` vars from the running process.

* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).
* Further clean up the lexer
- Consolidate the logic of the various token builders into a single type
- Improve and clean up the event-driven BlockParser
- Clean up comment parsing. Comments now contain their original leading
whitespace as well as trailing whitespace, and know how to move some
leading whitespace back into the body based on how the lexer decides
to dedent the comments. This preserves the original whitespace
information while still making it straight-forward to eliminate leading
whitespace in help comments.
