Full Changelog: belav/csharpier@1.2.0...1.2.1

1.2.0

What's Changed

Custom XML Parser #​1679

CSharpier now has a custom xml parser. XmlDocument and XDocument do not provide the original white space or the original attribute values from the file that was parsed which blocked the ability to implement supporting keeping empty new lines and not automatically encoding attributes.

Support for keeping empty lines in xml files #​1599

CSharpier now supports keeping a single empty line between elements in xml files. It will remove any initial or trailing empty lines.

<!-- input -->
<Root>

  <Element />


  <Element />

</Root>

<!-- expected output -->
<Root>
  <Element />

  <Element />
</Root>

<!-- 1.1.2 -->

  <Element />
</Root>

Xml - don't automatically encode attribute values #​1610

CSharpier will no longer encode attribute values. It will leave them encoded if they are supplied that way.

<!-- input & expected output -->
<Target Name="Transform" BeforeTargets="Build">
  <Message Importance="high" Text="@(MyItems->'MyItems has %(Identity)', ', ')" />
</Target>

<!-- 1.1.2 -->
<Target Name="Transform" BeforeTargets="Build">
  <Message Importance="high" Text="@(MyItems-&gt;'MyItems has %(Identity)', ', ')" />
</Target>

Add option to all integrations to report incorrect formatting as a warning instead of error #​1687

Formatting "using" import split on multiple lines requires formatting it twice to get the expected result #​1698

When a using contained a newline before the namespace it was not being sorted properly.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
