* uniq: Add counting option (WIP!)
Usage:
fetch https://raw.githubusercontent.com/timbray/topfew/master/test/data/access-1k | lines | wrap item | uniq | sort-by count | last 10
* uniq: Add first test
* uniq: Re-enable the non-counting variant.
* uniq: Also handle primitive lines.
* uniq: Update documentation
* uniq: Final comment about error handling. Let's get some feedback
* uniq: Address review comments.
Not happy with the way I create a TypeError. There must be a cleaner
way. Anyway, good for shipping.
* uniq: Use Labeled_error as suggested by jturner in chat.
* uniq: Return error directly.

* Move sum tests into math directory
* Move sum documentation over to math documentation
One sum example already existed in the math examples and a few of the others were outdated and didn't work, so I only moved one over, and updated their output
* Remove no-longer-in-use mod statement
* Add support to allow the week day start in cal to be configurable
* Fix variable name
* Use a flag instead of a configuration setting for specifying the starting day of the week
* Add 'every' command
* Add --skip option to 'every' command
This option skips instead of selects every nth row
* Fix descriptions for 'every' command
* Add docummentation for 'every' command
* Check actual filenames in 'every' command tests
* Converting average.rs to math.rs
* Making some progress towards math
Examples and unit tests failing, also think I found a bug with passing in strings
* Fix typos
* Found issue with negative numbers
* Add some comments
* Split commands like in split and str_ but do not register?
* register commands in cli
* Address clippy warnings
* Fix bad examples
* Make the example failure message more helpful
* Replace unwraps
* Use compare_values to avoid coercion issues
* Remove unneeded code
* WIP - not compiling
* compiling but panicing
* still broken
* nearly working
* reverted deserializer_string changes
updated enter.rs and open.rs to use Option<Tagged<String>>
Accepted Clippy suggestions
Accepted fmt suggestions
Left original code from open.rs
We may want to use some of it and only fallback to encoding.
* Don't exit when there is an unknown encoding.
* When encoding is unknown default to utf-8.
* only do encoding if the user says to it
* merged some conflicts on open
* made error messages consistent
* Updated unwrap with expect
* updated open test to pass with more descriptive err
updated enter test to not fail
* change _location to location
* changed _visitor to visitor
* Added a more verbose usage statement for encoding

Primarily, instead of building a parse pattern enum, we just build the regex
directly, with the appropriate capture group names so that the column name
codepaths can be shared between simple and `--regex` patterns.
Also removed capture group count compared to column name count. I don't think
this codepath can possibly be reached with the regex we now use for the
simplified capture form.
* Show error when trying to sort by invalid column
* Added test for changes
* Addressed comments, updated test
* Removed unnecessary mutable keyword
* Changed split-column to solt column after rebase from upstream
* Adding iniitial draft for the addition of the count column on the histogram command
* Update histogram documentation
* Add count column test to histogram command
* Fix error in histogram documentation
* Don't include year and month by default, adds an option to display the quarters of the year
* Add a test for cal that checks that year requested is in the return
* rustfmt the cal tests
* Add cal command
* Fix docmentation to show commands on two lines
* Use bullet points on flag documentation for cal
* Dereference day before calling string method
* Silence Clippy warning regarding a function with too many arguments
* Update cal flag descriptions and documentation
* Add some tests for the cal command
* make trim apply to strings contained in tables (also at deeper nesting
levels), not just top-level strings
* remove unnecessary clone (thanks clippy)
* fix: absolutize path against its parent if it was a symlink.
On Linux this happens because Rust calls readlink but doesn't canonicalize the resultant path.
* feat: playground function to create symlinks
* fix: use playground dirs
* feat: test for #1631, shift tests names
* Refactor InputStream and affected commands.
First, making `values` private and leaning on the `Stream` implementation makes
consumes of `InputStream` less likely to have to change in the future, if we
change what an `InputStream` is internally.
Second, we're dropping `Option<InputStream>` as the input to pipelines,
internals, and externals. Instead, `InputStream.is_empty` can be used to check
for "emptiness". Empty streams are typically only ever used as the first input
to a pipeline.
* Add run_external internal command.
We want to push external commands closer to internal commands, eventually
eliminating the concept of "external" completely. This means we can consolidate
a couple of things:
- Variable evaluation (for example, `$it`, `$nu`, alias vars)
- Behaviour of whole stream vs per-item external execution
It should also make it easier for us to start introducing argument signatures
for external commands,
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs

* Insert Column[index] if no header info is found.
* Update error description
* Add initial test

* Add empty sheet to test file
* Revert "Add empty sheet to test file"
This reverts commit a4bf38a31d.
* Show error message when given empty table
* 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
* Add test
* Custom canonicalize method for FilesystemShell.
* Use custom canonicalize method.
Fixed missing import.
* Move function body to already impl body.
* Create test that aims to resolve.
This improves incremental build time when working on what was previously
the root package. For example, previously all plugins would be rebuilt
with a change to `src/commands/classified/external.rs`, but now only
`nu-cli` will have to be rebuilt (and anything that depends on it).
