# Description Closes: #15755 I think it's a good feature, to achieve this, we need to get all hidden envs(it's defined in `get_hidden_env_vars`, and then restore these envs back to stack) # User-Facing Changes ### Before ```nushell > $env.foo = 'bar' > overlay new xxx > hide-env foo > overlay hide xxx > $env.foo Error: nu:🐚:column_not_found × Cannot find column 'foo' ╭─[entry #21:5:1] 4 │ overlay hide xxx 5 │ $env.foo · ────┬───┬ · │ ╰── value originates here · ╰── cannot find column 'foo' ╰──── ``` ### After ```nushell > $env.foo = 'bar' > overlay new xxx > hide-env foo > overlay hide xxx > $env.foo bar ``` ## Note But it doesn't work if it runs the example code in script: `nu -c "$env.foo = 'bar'; overlay new xxx; hide-env foo; overlay hide xxx; $env.foo"` still raises an error says `foo` doesn't found. That's because if we run the script at once, the envs in stack doesn't have a chance to merge back into `engine_state`, which is only called in `repl`. It introduces some sort of inconsistency, but I think users use overlays mostly in repl, so it's good to have such feature first. # Tests + Formatting Added 2 tests # After Submitting NaN
Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
