# Description <!-- Thank you for improving Nushell. Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> Replaces #8824, which was languishing in review limbo and becoming increasingly difficult to keep current with upstream changes. In addition to all the edits, this PR includes updated documentation for running unit tests via `std run-tests`. # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> A CONTRIBUTING.md documenting guidelines and getting started info for potential stdlib contributors. # Tests + Formatting <!-- Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass - `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the standard library > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` --> # 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. │
. . .
├────┼─────────────────────────────┼────────────────────────────────────────────────────────────────┤
│ # │ name │ usage │
╰────┴─────────────────────────────┴────────────────────────────────────────────────────────────────╯
🧰 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.
