Upgrade notes

This document contains notes to help upgrade from previous versions of PSDocs.

Upgrade to v0.9.0

Follow these notes to upgrade to v0.9.0 from previous versions.

Empty documents

Previously output would be generated from any Document block.

For example:

Document 'WithTitle' {
    Title 'Read me'
    Metadata @{
        key = 'value'
    }
}

Documents that do not generate any body content are ignored. If a document only sets a title or metadata the document is ignored. To generate a document, set any body content.

For example:

Document 'WithText' {
    Title 'Read me'

    'Some content'
}

Document 'WithBlockQuote' {
    Title 'Read me'

    'Some content' | BlockQuote
}

Upgrade to v0.7.0

Follow these notes to upgrade to v0.7.0 from previous versions.

Inline blocks

Previously a Document block and the command that generated the document could be called inline within the same script.

For example:

Document 'SampleMessage' {
    'Testing 123.'
}

Sample -InputObject @{ }

Support for inline Document blocks has been removed. Use the following steps to migrate inline blocks to a file if you previously used this feature:

  • Create a new file ending with .Doc.ps1 file extension. For example Sample.Doc.ps1.
  • Copy and paste the previous inline Document block into the file. Multiple document blocks can be included in the same file.
  • Update command-line to use Invoke-PSDocument instead of using the name of the document block directly.

Example Sample.Doc.ps1:

Document 'SampleMessage' {
    'Testing 123.'
}

The cmdlet Invoke-PSDocument can be called as follows:

Invoke-PSDocument -Path .\Sample.Doc.ps1 -Name SampleMessage;

On Linux, the file extension .doc.ps1 is not automatically found by PSDocs because of file system case-sensitivity. For consistency, use .Doc.ps1 on all platforms.

Helper functions

Previously helper functions could be defined with the default scope.

For example:

function SampleHelperFn {
    # Do something
}

Document 'SampleDocument' {
    SampleHelperFn;
}

The execution model of PSDocs now uses a separate runspace sandbox. Blocks are enumerated first then executed. Helper functions can still be used however must be flagged with the global scope modifier.

For example:

function global:SampleHelperFn {
    # Do something
}

Document 'SampleDocument' {
    SampleHelperFn;
}

Script block usage of Note and Warning

Previously Note and Warning blocks could contain a script block.

For example:

Document 'NoteScriptBlock' {
    Note {
        'A note'
    }
}

This syntax was deprecated as of v0.6.0, and has been removed as of v0.7.0. Instead of using a script block, pipe the note or warning text to Note, Warning.

For example:

Document 'NotePipe' {
    'A note' | Note
}

Section -When parameter

Previously the -When parameter could be used with the section keyword.

For example:

Document 'SectionWhen' {
    Section -When { $i -eq 0 } {
        'Sample section text.'
    }
}

The -When parameter was replaced with -If as of v0.6.0, and has been removed as of v0.7.0. Instead of using -When, update section blocks to use -If.

For example:

Document 'SectionIf' {
    Section -If { $i -eq 0 } {
        'Sample section text.'
    }
}
