# Description A slower, gentler alternative to #14531, in that we're just moving one setting *out* of `default_env.nu` in this PR ;-). All this does is transition from using `$env.NU_LIB_DIRS` in the startup config to `const $NU_LIB_DIRS`. Also updates the `sample_env.nu` to reflect the changes. Details: Before: `$env.NU_LIB_DIRS` was unnecessary set both in `main()` and in `default_env.nu` After: `$env.NU_LIB_DIRS` is only set in `main()` Before: `$env.NU_LIB_DIRS` was set to `config-dir/scripts` and `data-dir/completions` After: `$env.NU_LIB_DIRS` is set to an empty list, and `const NU_LIB_DIRS` is set to the directories above Before: Using `--include-path (-I)` would set the `$env.NU_LIB_DIRS` After: Using `--include-path (-I)` sets the constant `$NU_LIB_DIRS` # User-Facing Changes There shouldn't be any breaking changes here. The `$env.NU_LIBS_DIRS` still works for most cases. There are a few areas we need to clean-up to make sure that the const is usable (`nu-check`, et. al.) but they will still work in the meantime with the older `$env` version. # Tests + Formatting * Changed the Type-check on the `$env` version. * Added a type check for the const version. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting Doc updates
Nushell REPL
This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.
Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
