Path Command Enhancement Project (#2742) * Add string argument support for path subcommands * Add --replace option to 'path extension' command * Add examples of replacing for path extension * Refactor path extension and its example * Add replacement functionality to path basename * Refactor path subcommands to support more args This adds a lot of redundancy to non-relevant subcommands such as type, exists or expand. * Add replace and num_levels options to path dirname * Rename num_levels option to num-levels * Remove commented code * Clean up path basename * Fix path dirname description * Add path filestem opts; Rename extension -> suffix * Add prefix option and examples to path filestem * Fix broken num-levels of path dirname * Fix failing example test of path filestem * Fix failing test of path extension * Formatting * Add Windows-specific path subcommand examples `path expand` is still broken but otherwise seems to fix all examples on Windows * Fix weird path expand on Windows Also disable example tests for path expand. Failed caconicalization (e.g., due to path not existing) returns the original path so the examples always fail. * Formatting * Return path datatype when appropriate * Do not append empty remainder to path dirname * Add tests for path subcommands * Formatting * Revisit path subcommand description strings * Apply clippy suggestions; Formatting * Remove problematic test checking '~' expansion Wouldn't run on minimal due to useing optional dependency. The test success was also deending on the presence of home dir on the testing machine which might not be completely robust. * Add missing newline to file

Table content rolling. (#3097) 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 ```

90 degree table rotations (clockwise and counter-clockwise) (#3086) Also for 180 degree is expected. Rotation is not exactly like pivoting (transposing) for instance, given the following table: ``` > echo [[col1, col2, col3]; [cell1, cell2, cell3] [cell4, cell5, cell6]] ───┬───────┬───────┬─────── # │ col1 │ col2 │ col3 ───┼───────┼───────┼─────── 0 │ cell1 │ cell2 │ cell3 1 │ cell4 │ cell5 │ cell6 ───┴───────┴───────┴─────── ``` To rotate it counter clockwise by 90 degrees, we can resort to first transposing (`pivot`) them adding a new column (preferably integers), sort by that column from highest to lowest, then remove the column and we have a counter clockwise rotation. ``` > echo [[col1, col2, col3]; [cell1, cell2, cell3] [cell4, cell5, cell6]] | pivot | each --numbered { = $it.item | insert idx $it.index } | sort-by idx | reverse | reject idx ───┬─────────┬─────────┬───────── # │ Column0 │ Column1 │ Column2 ───┼─────────┼─────────┼───────── 0 │ col3 │ cell3 │ cell6 1 │ col2 │ cell2 │ cell5 2 │ col1 │ cell1 │ cell4 ───┴─────────┴─────────┴───────── ``` Which we can get easily, in this case, by doing: ``` > echo [[col1, col2, cel3]; [cell1, cell2, cell3] [cell4, cell5, cell6]] | rotate counter-clockwise ───┬─────────┬─────────┬───────── # │ Column0 │ Column1 │ Column2 ───┼─────────┼─────────┼───────── 0 │ col3 │ cell3 │ cell6 1 │ col2 │ cell2 │ cell5 2 │ col1 │ cell1 │ cell4 ───┴─────────┴─────────┴───────── ``` There are also many powerful use cases with rotation, it makes a breeze creating tables with many columns, say: ``` echo 0..12 | rotate counter-clockwise | reject Column0 ───┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬──────────┬──────────┬──────────┬────────── # │ Column1 │ Column2 │ Column3 │ Column4 │ Column5 │ Column6 │ Column7 │ Column8 │ Column9 │ Column10 │ Column11 │ Column12 │ Column13 ───┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼──────────┼──────────┼──────────┼────────── 0 │ 0 │ 1 │ 2 │ 3 │ 4 │ 5 │ 6 │ 7 │ 8 │ 9 │ 10 │ 11 │ 12 ───┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴──────────┴──────────┴──────────┴────────── ```

Obey precedence rules in which; Fix #2875 (#2885) * Obay precedence rules in which; Fix #2875 Before which did not obay the precedence of alias before def commands. Furthermore, `which -a echo` would only report either an alias or a def command or an internal command with the provided name. Not all. With this commit applied its fixed :) Example: ```shell /home/leo/repos/nushell(fix/which_reports_wrong_usage)> def echo [] {^echo hi} /home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo hi /home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo ───┬──────┬──────────────────────────┬───────── # │ arg │ path │ builtin ───┼──────┼──────────────────────────┼───────── 0 │ echo │ Nushell custom command │ No 1 │ echo │ Nushell built-in command │ Yes 2 │ echo │ /usr/bin/echo │ No ───┴──────┴──────────────────────────┴───────── /home/leo/repos/nushell(fix/which_reports_wrong_usage)> alias echo = ^echo hi there /home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo hi there /home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo ───┬──────┬──────────────────────────┬───────── # │ arg │ path │ builtin ───┼──────┼──────────────────────────┼───────── 0 │ echo │ Nushell alias │ No 1 │ echo │ Nushell custom command │ No 2 │ echo │ Nushell built-in command │ Yes 3 │ echo │ /usr/bin/echo │ No ───┴──────┴──────────────────────────┴───────── ``` * Fix clippy lint * Fix vec always Some even if empty
