about_psdocs_variables SHORT DESCRIPTION Describes the automatic variables that can be used within PSDocs document definitions. LONG DESCRIPTION PSDocs lets you generate dynamic markdown documents using PowerShell blocks. To generate markdown, a document is defined inline or within script files by using the `document` keyword. Within a document definition, PSDocs exposes a number of automatic variables that can be read to assist with dynamic document generation. Overwriting these variables or variable properties is not supported. The following variables are available for use: - $Culture - $Document - $InstanceName - $InputObject - $Section CULTURE The name of the culture currently being processed. `$Culture` is set by using the `-Culture` parameter of `Invoke-PSDocument` or inline functions. When more than one culture is set, each will be processed sequentially. If a culture has not been specified, `$Culture` will default to the culture of the current thread. Syntax: $Culture DOCUMENT An object representing the current object model of the document during generation. The following section properties are available for public read access: - `Title` - The title of the document. - `Metadata` - A dictionary of metadata key/value pairs. - `Path` - The file path where the document will be written to. Syntax: $Document Examples: document 'Sample' { Title 'Example' # The value of $Document.Title = 'Example' "The title of the document is $($Document.Title)." Metadata @{ author = 'Bernie' } # The value of $Document.Metadata['author'] = 'Bernie' 'The author is ' + $Document.Metadata['author'] + '.' } ```text author: Bernie EXAMPLE The title of the document is Example. The author is Bernie. ### InstanceName The name of the instance currently being processed. `$InstanceName` is set by using the `-InstanceName` parameter of `Invoke-PSDocument` or inline functions. When more than one instance name is set, each will be processed sequentially. If an instance name is not specified, `$InstanceName` will default to the name of the document definition. Syntax: powershell $InstanceName ### InputObject The value of the pipeline object currently being processed. `$InputObject` is set by using the `-InputObject` parameter of `Invoke-PSDocument` or inline functions. When more than one input object is set, each object will be processed sequentially. If an input object is not specified, `$InputObject` will default to `$Null`. Syntax: powershell $InputObject ### Section An object of the document section currently being processed. As `Section` blocks are processed, the `$Section` variable will be updated to match the block that is currently being processed. `$Section` will be the current document outside of `Section` blocks. The following section properties are available for public read access: - `Title` - The title of the section, or the document (when outside of a section block). - `Level` - The section heading depth. This will be _2_ (or greater for nested sections), or _1_ (when outside of a section block). Syntax: powershell $Section Examples: powershell document 'Sample' { Section 'Introduction' { # The value of $Section.Title = 'Introduction' "The current title is $($Section.Title)." } } text Introduction The current section title is Introduction. ``` NOTE An online version of this document is available at https://github.com/BernieWhite/PSDocs/blob/master/docs/concepts/PSDocs/en-US/about_PSDocs_Variables.md.
