* Disable clickable links when we can't get metadata of files
Fixes#6498
* Refactor path name rendering related code
* Make clickable links smarter
* Remove unneeded clone
* Return early if `use_ls_colors` is disabled
* 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`
