fixes #10455 @KAAtheWiseGit, I'm sorry, I didn't mean to block your first PR #10461, didn't see you had submitted it till I got around to submitting this. If you want to incoporate useful ideas from this PR into yours, I do not mind deferring to you. # Description Changes made in `datetime-diff`: * Initialize millisecond and microsecond fields in `$current`, to fix the error when borrow needs to refer to them. * Fix `borrow_nanoseconds` to borrow from seconds, not from (unused) microseconds. * Added error check to insist that first argument is >= second argument. `datetime-diff` doesn't represent negative durations correctly (it tries to borrow out of the year, resulting in negative year and positive all other fields). We don't currently have a use case requiring negative durations. * Add comments so help is a bit clearer (I was surprised that the first argument, named `$from` was actually supposed to be the *later* datetime. The order of arguments is reasonable (reminiscent of <later> <minus> <earlier>), so I just changed the param name to match its purpose. Changes made in `pretty-print-duration`: * changed type of argument from `duration` to `record`. (it's not clear why Nu was not complaining about this!) * changed test for skipping a clause from `> 0` to `!= 0`. Even though `datetime-diff` won't present a negative field in the record, user might call `pretty-print-duration` with one, might as well handle it. (but I think `hour:-2` will be rendered as `-2hr`, not `-2hrs`...). * added help and an example. # User-Facing Changes none requiring code changes. # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` - - # After Submitting <!-- If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date. --> |

Welcome to the standard library of `nushell`!
The standard library is a pure-nushell collection of custom commands which
provide interactive utilities and building blocks for users writing casual scripts or complex applications.
To see what's here:
> use std
> help commands | select name usage | where name =~ "std "
╭────┬─────────────────────────────┬────────────────────────────────────────────────────────────────╮
│ # │ name │ usage │
├────┼─────────────────────────────┼────────────────────────────────────────────────────────────────┤
│ 0 │ std assert │ Universal assert command │
│ 1 │ std assert equal │ Assert $left == $right │
. . .
│ 11 │ std clip │ put the end of a pipe into the system clipboard. │
│ 12 │ std dirs add │ Add one or more directories to the list. │
. . .

🧰 Using the standard library in the REPL or in scripts
All commands in the standard library must be "imported" into the running environment
(the interactive read-execute-print-loop (REPL) or a .nu script) using the
use command.
You can choose to import the whole module, but then must refer to individual commands with a std prefix, e.g:
use std
std log debug "Running now"
std assert (1 == 2)
Or you can enumerate the specific commands you want to import and invoke them without the std prefix.
use std ["log debug" assert]
log debug "Running again"
assert (2 == 1)
This is probably the form of import you'll want to add to your env.nu for interactive use.
