| excerpt: Today, we're releasing version 0.69 of Nu. This is release continues to make nushell nicer. | ||
| --- | ||
|
|
||
| # Nushell 0.69 | ||
|
|
||
| Nushell, or Nu for short, is a new shell that takes a modern, structured approach to your commandline. It works seamlessly with the data from your filesystem, operating system, and a growing number of file formats to make it easy to build powerful commandline pipelines. | ||
|
|
||
| Today, we're releasing version 0.69 of Nu. | ||
| <!-- more --> | ||
|
|
||
| # Where to get it | ||
|
|
||
| Nu 0.69 is available as [pre-built binaries](https://github.com/nushell/nushell/releases/tag/0.69.1) or from [crates.io](https://crates.io/crates/nu). Note: this release is officially "0.69.1" because of a last-minute issue that was found and fixed. If you have Rust installed you can install it using `cargo install nu`. | ||
|
|
||
| If you want all the built-in goodies, you can install `cargo install nu --features=extra`. | ||
|
|
||
| As part of this release, we also publish a set of optional plugins you can install and use with Nu. To install, use `cargo install nu_plugin_<plugin name>`. | ||
|
|
||
| # Themes of this release | ||
|
|
||
| ## Finishing the rework of modules and environment ([WindSoilder, kubouch](https://github.com/nushell/nushell/pull/6468)) | ||
|
|
||
| If you followed the development since the last release, you might have noticed we successfully applied "the method of dead ends" pioneered by [Jára Cimrman](https://en.wikipedia.org/wiki/J%C3%A1ra_Cimrman): "Somebody had to probe this dead end of human knowledge and announce to the world: Not this way, friends!" | ||
| In short, the `source-env` experiment did not work out as planned. | ||
| We hoped to allow to call `source-env` with dynamic paths which, however, proved unfeasible. | ||
| Therefore, in this release, we remove all notions of `source-env` from Nushell and instead **`use` will be used activate the module's environment**. | ||
| Any call to `use` will run the module's `export-env { ... }` block (if there is one) and keep its environment. | ||
| A positive side of it is that one call of `use` is enough to import both commands/aliases and the environment, there is no need to call two separate commands as we planned for `source-env`. | ||
|
|
||
| We're also keeping the `source` command for now, as well as the current config file format. | ||
| One reason is that we want to first investigate whether it is possible to export also regular variables from modules and whether we can use the `module` keyword inside modules. | ||
| However, the use of modules is still preferred over `source` as it will become the default way in the future. | ||
|
|
||
| ### Summary of deprecations | ||
|
|
||
| Here is a recap of the table posted in the previous release post with updated entries. | ||
|
|
||
| | command | pre-previous release (0.67) | previous release (0.68) | this release (0.69) | | ||
| | ------------ | --------------------------------------------------- | ---------------------------------------------------------------------- | --------------------------------- | | ||
| | `source` | imports everything into the current scope | same (deprecated) | same (deprecated) | | ||
| | `source-env` | N/A | imports environment variables | removed | | ||
| | `use` | imports environment variables, commands and aliases | same | same | | ||
| | `hide` | hides enviornment variables, commands and aliases | same | hides only commands and aliases* | | ||
| | `hide-env` | hides environment variables | same | same | | ||
| | `export env` | defines a single environment variable in a module | same | removed | | ||
| | `export-env` | N/A | (in a module) defines the envrionment for the whole module | same | | ||
| | `export-env` | N/A | (in a script) when evaluated, preserves the environment from the block | same | | ||
| | `export ...` | only allowed in a module | allowed in a script as well | same | | ||
| | `config.nu` | plain script | plain script | plain script | | ||
| | `env.nu` | plain script | plain script | plain script | | ||
| | `login.nu` | plain script | plain script | plain script | | ||
|
|
||
| * Technically, `hide` still hides environment variables but it works in a "compatibility mode" that is intended to only serve its purpose in the virtualenv activation script. As soon as the virtualenv integration gets updated, hiding environment variables with `hide` will be removed completely. | ||
|
|
||
| ## Upcoming `virtualenv` activation changes (kubouch) | ||
|
|
||
| To reflect the recent changes to the module environment, we are changing the virtualenv integration to use overlays. | ||
| This will come in effect as soon as [this PR](https://github.com/pypa/virtualenv/pull/2422) gets merged. | ||
| In practice, this means that instead of `source activate.nu`, you'll use `overlay use activate.nu`, `deactivate` will work the same. | ||
|
|
||
| Under the hood, calling `overlay use activate.nu` will activate the `activate` overlay and `deactivate` is just an alias for calling `overlay hide activate`. | ||
| If you wish, you can manually name the overlay, for example `overlay use activate.nu as spam`, but then you'd need to remove it with `overlay hide spam` instead of `deactivate`. | ||
|
|
||
| ## Grammar Experiments (JT) | ||
|
|
||
| We've recently also started working on some improvements to Nushell's syntax. While these aren't part of Nushell 0.69, you can try this experimental syntax in our new [grammar](https://github.com/nushell/grammar) repo. Some experiments we're looking into: | ||
|
|
||
| Traditional function definition syntax | ||
| ``` | ||
| def foo(x: int) { ... } | ||
| ``` | ||
|
|
||
| Traditional function call syntax | ||
| ``` | ||
| foo(3) | ||
| ``` | ||
|
|
||
| And much more. We're hoping to talk more about these experiments as they mature. | ||
|
|
||
|
|
||
| # Breaking changes | ||
|
|
||
| We found a regression in the correctness of the `-d` and `-t` flags of `touch`. To get the release out, we've removed these flags, but hope to replace them with correct implementations in the future. | ||
|
|
||
| We also removed support for duration literals above weeks, including month, year, and decade literals. These were found to be confusing as it's unclear what a duration of a month is (30 days? 31 days?) | ||
|
|
||
| The `str collect` command is now `str join`. | ||
|
|
||
| # Next Steps | ||
|
|
||
| We've been progressing with our design towards 0.80 as outlined in [this Notion page](https://kubouch.notion.site/4db276462ba24704919edb4cc4b86be7?v=10506505557f4f7b9a65155128c04250). | ||
|
|
||
| Some time was spent trying out possible new syntax directions but we were not confident to release them yet. In the next release we'll see a removal of features deprecated in this release and we'll continue to push ahead for the 0.80. | ||
