add some startup performance metrics (#7851) # Description This PR changes the old performance logging with `Instant` timers. I'm not sure if this is the best way to do it but it does help reveal where time is being spent on startup. This is what it looks like when you launch nushell with `cargo run -- --log-level info`.

Fix: update engine_state when history.isolation is true (#9268) (#9616) <!-- if this PR closes one or more issues, you can automatically link the PR with them by using one of the [*linking keywords*](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword), e.g. - this PR should close #xxxx - fixes #xxxx you can also mention related issues, PRs or discussions! --> # Description Fixes #9268, the issue was due to the fact that when `history_isolation` was set to true the engine_state's `session_id` wasn't updated. This PR mainly refactors the code that updates the line_editor's history information into one function `update_line_editor_history` and also updates the engine_state's `session_id` when `history_isolation` is set to `true` by calling the function `store_history_id_in_engine`. <!-- Thank you for improving Nushell.

The test checks that after a call to the function `update_line_editor_history`, the `engine_state` and the returned `line_editor` do have the same `session_id`.

color_config now accepts closures as color values (#7141) # Description Closes #6909. You can now add closures to your `color_config` themes. Whenever a value would be printed with `table`, the closure is run with the value piped-in. The closure must return either a {fg,bg,attr} record or a color name (`'light_red'` etc.). This returned style is used to colour the value. This is entirely backwards-compatible with existing config.nu files. Example code excerpt: ``` let my_theme = { header: green_bold bool: { if $in { 'light_cyan' } else { 'light_red' } } int: purple_bold filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } } duration: purple_bold date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } } range: yellow_bold string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } } nothing: white ``` Example output with this in effect: ![2022-11-16 12 47 23 AM - style_computer rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952558-482de05d-69c7-4bf2-91fc-d0964bf71264.png) ![2022-11-16 12 39 41 AM - style_computer rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952580-2384bb86-b680-40fe-8192-71bae396c738.png) ![2022-11-15 09 21 54 PM - run_external rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952601-343fc15d-e4a8-4a92-ad89-9a7d17d42748.png) Slightly important notes: * Some color_config names, namely "separator", "empty" and "hints", pipe in `null` instead of a value. * Currently, doing anything non-trivial inside a closure has an understandably big perf hit. I currently do not actually recommend something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }` for serious work, mainly because of the abundance of string-type data in the world. Nevertheless, lesser-used types like "date" and "duration" work well with this. * I had to do some reorganisation in order to make it possible to call `eval_block()` that late in table rendering. I invented a new struct called "StyleComputer" which holds the engine_state and stack of the initial `table` command (implicit or explicit). * StyleComputer has a `compute()` method which takes a color_config name and a nu value, and always returns the correct Style, so you don't have to worry about A) the color_config value was set at all, B) whether it was set to a closure or not, or C) which default style to use in those cases. * Currently, errors encountered during execution of the closures are thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors result in a huge perf hit when they are encountered. I think what should be done is to assume something terrible happened to the user's config and invalidate the StyleComputer for that `table` run, thus causing subsequent output to just be Style::default().) * More thorough tests are forthcoming - ran into some difficulty using `nu!` to take an alternative config, and for some reason `let-env config =` statements don't seem to work inside `nu!` pipelines(???) * The default config.nu has not been updated to make use of this yet. Do tell if you think I should incorporate that into this. # User-Facing Changes See above. # Tests + Formatting Don't forget to add tests that cover your changes.

So, using a few find-replaces regexes, I increased their usage.

enable history isolation (#9063) # Description This PR impacts the nushell sqlite history only. This is the first PR that enables history isolation in nushell for the sqlite history. Hopefully, we can continue building on this. This PR allows "history isolation" which means that other nushell session's history won't be available in the current session when using the uparrow/downarrow history navigation. This change only impacts the uparrow downarrow history navigation. What remains to be done is making ctrl+r history menu respect this setting too. Right now, the history menu will still show you all entries from all sessions. The history command also shows all history items from all sessions. This may remain unchanged since you can just filter by history session right now. This also fixes a bug where the session id is 0 in the sqlite history since my April 18th reedline PR.

color_config now accepts closures as color values (#7141) # Description Closes #6909. You can now add closures to your `color_config` themes. Whenever a value would be printed with `table`, the closure is run with the value piped-in. The closure must return either a {fg,bg,attr} record or a color name (`'light_red'` etc.). This returned style is used to colour the value. This is entirely backwards-compatible with existing config.nu files. Example code excerpt: ``` let my_theme = { header: green_bold bool: { if $in { 'light_cyan' } else { 'light_red' } } int: purple_bold filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } } duration: purple_bold date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } } range: yellow_bold string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } } nothing: white ``` Example output with this in effect: ![2022-11-16 12 47 23 AM - style_computer rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952558-482de05d-69c7-4bf2-91fc-d0964bf71264.png) ![2022-11-16 12 39 41 AM - style_computer rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952580-2384bb86-b680-40fe-8192-71bae396c738.png) ![2022-11-15 09 21 54 PM - run_external rs_-_nushell_-_VSCodium](https://user-images.githubusercontent.com/83939/201952601-343fc15d-e4a8-4a92-ad89-9a7d17d42748.png) Slightly important notes: * Some color_config names, namely "separator", "empty" and "hints", pipe in `null` instead of a value. * Currently, doing anything non-trivial inside a closure has an understandably big perf hit. I currently do not actually recommend something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }` for serious work, mainly because of the abundance of string-type data in the world. Nevertheless, lesser-used types like "date" and "duration" work well with this. * I had to do some reorganisation in order to make it possible to call `eval_block()` that late in table rendering. I invented a new struct called "StyleComputer" which holds the engine_state and stack of the initial `table` command (implicit or explicit). * StyleComputer has a `compute()` method which takes a color_config name and a nu value, and always returns the correct Style, so you don't have to worry about A) the color_config value was set at all, B) whether it was set to a closure or not, or C) which default style to use in those cases. * Currently, errors encountered during execution of the closures are thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors result in a huge perf hit when they are encountered. I think what should be done is to assume something terrible happened to the user's config and invalidate the StyleComputer for that `table` run, thus causing subsequent output to just be Style::default().) * More thorough tests are forthcoming - ran into some difficulty using `nu!` to take an alternative config, and for some reason `let-env config =` statements don't seem to work inside `nu!` pipelines(???) * The default config.nu has not been updated to make use of this yet. Do tell if you think I should incorporate that into this. # User-Facing Changes See above. # Tests + Formatting Don't forget to add tests that cover your changes.

FEATURE: add the startup time to `$nu` (#8353) # Description in https://github.com/nushell/nushell/issues/8311 and the discord server, the idea of moving the default banner from the `rust` source to the `nushell` standar library has emerged :yum: however, in order to do this, one need to have access to all the variables used in the default banner => all of them are accessible because known constants, except for the startup time of the shell, which is not anywhere in the shell... #### this PR adds exactly this, i.e. the new `startup_time` to the `$nu` variable, which is computed to have the exact same value as the value shown in the banner. ## the changes in order to achieve this, i had to - add `startup_time` as an `i64` to the `EngineState` => this is, to the best of my knowledge, the easiest way to pass such an information around down to where the banner startup time is computed and where the `$nu` variable is evaluated - add `startup-time` to the `$nu` variable and use the `EngineState` getter for `startup_time` to show it as a `Value::Duration` - pass `engine_state` as a `&mut`able argument from `main.rs` down to `repl.rs` to allow the setter to change the value of `startup_time` => without this, the value would not change and would show `-1ns` as the default value... - the value of the startup time is computed in `evaluate_repl` in `repl.rs`, only once at the beginning, and the same value is used in the default banner :ok_hand: # User-Facing Changes one can now access to the same time as shown in the default banner with ```bash $nu.startup-time ``` # Tests + Formatting - :green_circle: `cargo fmt --all` - :green_circle: `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` - :green_circle: `cargo test --workspace` # After Submitting ``` $nothing ```
