# Description
Part of the larger cratification effort.
Moves all `reedline` or shell line editor specific commands to `nu-cli`.
## From `nu-cmd-lang`:
- `commandline`
- This shouldn't have moved there. Doesn't directly depend on reedline
but assumes parts in the engine state that are specific to the use of
reedline or a REPL
## From `nu-command`:
- `keybindings` and subcommands
- `keybindings default`
- `keybindings list`
- `keybindings listen`
- very `reedline` specific
- `history`
- needs `reedline`
- `history session`
## internal use
Instead of having a separate `create_default_context()` that calls
`nu-command`'s `create_default_context()`, I added a `add_cli_context()`
that updates an `EngineState`
# User-Facing Changes
None
## Build time comparison
`cargo build --timings` from a `cargo clean --profile dev`
### total
main: 64 secs
this: 59 secs
### `nu-command` build time
branch | total| codegen | fraction
---|---|---|---
main | 14.0s | 6.2s | (44%)
this | 12.5s | 5.5s | (44%)
`nu-cli` depends on `nu-command` at the moment.
Thus it is built during the code-gen phase of `nu-command` (on 16
virtual cores)
# Tests + Formatting
I removed the `test_example()` facilities for now as we had not run any
of the commands in an `Example` test and importing the right context for
those tests seemed more of a hassle than the duplicated
`test_examples()` implementations in `nu-cmd-lang` and `nu-command`
