b9-0.5.67: CHANGELOG.md

# Changelog for B9

## 0.5.67

* Iron out UTF-8 decoding issues

  * Use `Data.Text` in more places

  * Remove `ByteStringGenerator`

  * Change `ToContentGenerator` to produce only (strict) `Data.Text.Text`s

* Add `B9.Text` a module with conversion functions for different string types.

* Add helper functions and type for Erlang parsing:

  * `textToErlangAst`,

  * `stringToErlangAst` and

  * `ErlangAST`

## 0.5.66

* Fix the Nix package:

  * Get rid of the virsh path configuration item

  * Allow setting the path to @/.../libexec/libvirt_lxc@ via environment variable

## 0.5.65

* Refactor the B9 Monad to use `extensible-effects`

## 0.5.64

* Refactor and prepare for more drastic changes

* Fix runtime errors due to `undefined` values in the environment

## 0.5.63

* Depend on `shake-0.17.6` to fix build errors

## 0.5.62

* Rewrite `B9.Shake.SharedImageRules` in line with
  Shake's example for custom rules

* Replace `ConcatableSyntax` by using `Binary` instances, and also

  * Remove/Inline `encodeSyntax` by using `Binary.encode`

  * Rename `decodeSyntax` to `decodeOrFail'` and delegate to `Binary.decodeOrFail`.

* Add a newtype wrapper around `YamlObject` for **cloud-init** yaml documents
  `CloudConfigYaml`

  This new type serves the purpose of add the `#cloud-config`
  line to the top of the generated yaml document,
  as [required by cloud-init](https://cloudinit.readthedocs.io/en/latest/topics/format.html#cloud-config-data).

  The `Binary` instance adds this **header line** and
  delegates the rendering of the yaml document to
  `YamlObject`.

* Remove the rendering of this header line in the `YamlObject`
  `Binary` instance.

* Rename `RenderYaml` to `RenderYamlObject` In order to prevent unexpected
  runtime behaviour in code that uses this library.

* Introduce the type `Environment` that replaces the ubiquotus `[(String, String)]`
  by a lazy `Text` based `HashMap`.

* Add `addLocalPositionalArguments`

* Rename the previous `B9.Artifact.Content` to `B9.Artifact.Content`

* Introduce `ContentGenerator` as an open, extensible alternative
  to `Content`, `AST` and `CanRender` in the module
  `B9.Artifact.Content`
* Rename-and-Split refactor `B9.ArtifactSource{Impl}` to `B9.Artifact.Generator.{..}`

* Move `CanRender` from `B9.Artifact.Content.AST` to `B9.Artifact.Content`

* Switch to lazy `Text`s and `ByteString`s where possible, since B9 might
  read/generate large files.

* Rename `CanRender` to `ToContentGenerator`
  and change the method signatur to return the new `ContentGenerator` type

* Fix spelling: Rename B9Invokation to B9Invocation

* Rename `FromAST` to `FromAST`

* Rearrange modules for content generation:

  * Introduce `Content.FromByteString`

  * Remove deprecated `Concatenation`
