* Ignore `cargo tarpaulin` output files
* Add expected result for `columns` example
Examples without provided expected output will never be tested.
The subset of commands available in `test_examples()` is limited thus
excluding the tests depending on other commands
* Add example test harness to `reject`
* Test and fix `wrap` example
* Test and fix `drop column` example
* Update `from ods` examples
* Update `from xlsx` examples
* Run `to nuon` examples
* Run `hash base64` examples
* Add example output to `path parse`
* Test and fix the `grid` examples
* Do not pass non-string env vars to externals
Also misc cleanup
* Add note to default config
* Add a test
* Ensure PATH/Path conversion list <-> string
At the moment `crossterm` apparently has a regression decoding certain important key combinations on Windows.
Thus reedline reverted to the previous version.
Some changes are necessary to remove the need for `crossterm` in the use of `lscolors`.
Introduces two local conversion traits.
Additionally update the `Highlighter` API to support the cursor
position.
This will enable brace/statement match highlighting.
Same rationale as in #4378
Also accelerate `grid`

* Use only $nu.env.PWD for getting current directory
Because setting and reading to/from std::env changes the global state
shich is problematic if we call `cd` from multiple threads (e.g., in a
`par-each` block).
With this change, when engine-q starts, it will either inherit existing
PWD env var, or create a new one from `std::env::current_dir()`.
Otherwise, everything that needs the current directory will get it from
`$nu.env.PWD`. Each spawned external command will get its current
directory per-process which should be thread-safe.
One thing left to do is to patch nu-path for this as well since it uses
`std::env::current_dir()` in its expansions.
* Rename nu-path functions
*_with is not *_relative which should be more descriptive and frees
"with" for use in a followup commit.
* Clone stack every each iter; Fix some commands
Cloning the stack each iteration of `each` makes sure we're not reusing
PWD between iterations.
Some fixes in commands to make them use the new PWD.
* Post-rebase cleanup, fmt, clippy
* Change back _relative to _with in nu-path funcs
Didn't use the idea I had for the new "_with".
* Remove leftover current_dir from rebase
* Add cwd sync at merge_delta()
This makes sure the parser and completer always have up-to-date cwd.
* Always pass absolute path to glob in ls
* Do not allow PWD a relative path; Allow recovery
Makes it possible to recover PWD by proceeding with the REPL cycle.
* Clone stack in each also for byte/string stream
* (WIP) Start moving env variables to engine state
* (WIP) Move env vars to engine state (ugly)
Quick and dirty code.
* (WIP) Remove unused mut and args; Fmt
* (WIP) Fix dataframe tests
* (WIP) Fix missing args after rebase
* (WIP) Clone only env vars, not the whole stack
* (WIP) Add env var clone to `for` loop as well
* Minor edits
* Refactor merge_delta() to include stack merging.
Less error-prone than doing it manually.
* Clone env for each `update` command iteration
* Mark env var hidden only when found in eng. state
* Fix clippt warnings
* Add TODO about env var reading
* Do not clone empty environment in loops
* Remove extra cwd collection
* Split current_dir() into str and path; Fix autocd
* Make completions respect PWD env var
* get_columns is working in the columns command
* the new location of the get_columns method is nu-protocol/src/column.rs
* reference the new location of the get_columns method
* move get_columns to nu-engine
* Proof of concept treating env vars as Values
* Refactor env var collection and method name
* Remove unnecessary pub
* Move env translations into a new file
* Fix LS_COLORS to support any Value
* Fix spans during env var translation
* Add span to env var in cd
* Improve error diagnostics
* Fix non-string env vars failing string conversion
* Make PROMPT_COMMAND a Block instead of String
* Record host env vars to a fake file
This will give spans to env vars that would otherwise be without one.
Makes errors less confusing.
* Add 'env' command to list env vars
It will list also their values translated to strings
* Sort env command by name; Add env var type
* Remove obsolete test
