# Description This PR adds raw string support by using `r#` at the beginning of single quoted strings and `#` at the end. Notice that escapes do not process, even within single quotes, parentheses don't mean anything, $variables don't mean anything. It's just a string. ```nushell ❯ echo r#'one\ntwo (blah) ($var)'# one\ntwo (blah) ($var) ``` Notice how they work without `echo` or `print` and how they work without carriage returns. ```nushell ❯ r#'adsfa'# adsfa ❯ r##"asdfa'@qpejq'## asdfa'@qpejq ❯ r#'asdfasdfasf ∙ foqwejfqo@'23rfjqf'# ``` They also have a special configurable color in the repl. (use single quotes though)  They should work like rust raw literals and allow `r##`, `r###`, `r####`, etc, to help with having one or many `#`'s in the middle of your raw-string. They should work with `let` as well. ```nushell r#'some\nraw\nstring'# | str upcase ``` closes https://github.com/nushell/nushell/issues/5091 # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> # 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 -A clippy::result_large_err` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass - `cargo run -- -c "use std testing; testing run-tests --path crates/nu-std"` 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. --> --------- Co-authored-by: WindSoilder <WindSoilder@outlook.com> Co-authored-by: Ian Manske <ian.manske@pm.me>
