- Replaced `start`/`end` with span. - Fixed standard library. - Add `help` option. - Add a couple more errors for invalid record types. Resolve #10914 # Description # User-Facing Changes - **BREAKING CHANGE:** `error make` now takes in `span` instead of `start`/`end`: ```Nushell error make { msg: "Message" label: { text: "Label text" span: (metadata $var).span } } ``` - `error make` now has a `help` argument for custom error help. |

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.
