pwsh-live-doc's Issues
Write example page for [Parameter(Mandatory)] not accepting an array if the first element is null
function MyFunc {
[CmdletBinding()]
param(
[Parameter(Mandatory)]
[Object[]] $Array
}
# this works
MyFunc @(1, 2, 3)
# this doesn't
MyFunc @($null, 1, 2, 3)Should also test with null in other positions in the array.
Add page about assigning to $null
$null = 4
Add page for whatever's going on here
PS> @(1, 5, 2) -eq 5
5
PS> @(1, 5, 2) -eq 6
PS> @(1, 5, 2) -eq 2
2
Add page about variable scopes/variable inheritance
Add `$null` to `PSCustomObject` `Count` section
Perform syntax highlighting at compile time
You can use highlightjs from npm to output highlighted code. That way the site doesn't need to load unnecessary javascript when the user browses to it.
This will require adding npm to this project.
Add page about script blocks and closures
/what a script block's environment actually is.
Add page about strict mode
$_ status variable
For example, can $_ be redefined in a child scope with nested ForEach-Objects?
Run multiple versions of Windows PowerShell with the version parameter
This can be done with powershell -Version [version]
Set up CI to run on a scheduled time
This doesn't need to be often. Just once a week, or every other day. The idea is that when new versions of PowerShell are released, we automatically pull them into our documentation without needing developers to add any commits.
Improve the site to be able to handle more than just a couple example topics
I think this will require a few changes:
- Generate and save the HTML generated from each example script
- This way the same static HTML can be used in multiple places
- Make a page for each example script
- The URL should be the script's title converted to all kebabcase (or snakecase maybe?)
- The
<title>element should be the script's title
- There should be a main page with links to a few random pages determined at page load
- There should be a sidebar with links to all pages
When we have more content, we'll also want to add a search box and categorization for pages (for example, we could have an "error handling" category that collapses pages under it on the sidebar). For now, however, this seems like a good start.
Write example page about how in versions before 6.1, PSCustomObjects don't have a count
PS> $object = [PSCustomObject]@{Name='TestObject'}
PS> $object.count
$nullRun tests against different instances of PowerShell in parallel
This shouldn't be too difficult, and could speed build time up by a bunch
Add page about the -Action parameter of Set-PSBreakPoint having side effects
For example the $? variable propagates out.
Look into printing to stderr in class method
For some reason, outputting to stderr from below a class method causes the method to fail early. At least I think that's what's happening? I reproed it with Invoke-Expression "pwsh -c stnhaosutnhou".
This might make a good page.
The "Method output" page produces different output on my machine than in GitHub Actions
Specifically, the section describing non-void methods when ErrorActionPreference is Continue. I'm not sure yet what causes the difference....
Also, no luck running 7.0.1 locally to match the runner.

Write example page for empty arrays condensing into nulls
For the function to not return null, you need ,@()
Also, this applies to returning things like Tuples as well. You need to do Tuple::Create((,@())).
Make a page that when calling Get-Member on an array, you should use -InputObject rather than pipe
Otherwise it will get the types of the array contents
Write example page about how `0 -eq ""` is true
The opposite isn't true though.
