Get-GitHubRepositoryLanguage for multiple repos?

[HowardWolosky]

I'm unable to repro your issue, and you failed to include any verbose logs (either by copy/pasting the relevant section of your log file, or by re-running the command with -Verbose) that would provide pointers into the issue that you're having.

For reference, this command works fine:

Get-GitHubRepositoryLanguage -OwnerName microsoft -RepositoryName powershellforgithub

returns:

PowerShell
----------
   1446793

@HowardWolosky, thank you for looking at the question. It requires querying multiple repos. Here is more information.

PS C:\> Get-GitHubRepositoryLanguage -OwnerName microsoft -RepositoryName PowerShellForGitHub

PowerShell
----------
   1446793

PS C:\> Get-GitHubRepositoryLanguage -OwnerName powershell -RepositoryName powershell

C#               : 30816340
PowerShell       : 5130858
Roff             : 216538

JavaScript       : 8738
Dockerfile       : 6482
Batchfile        : 24

However, when the two commands are run sequentially or in a script, the output contains only language 'PowerShell' information.

This is simply the nature of PowerShell ... nothing specific to this module.

This will produce the same result.

$a = Get-GitHubRepositoryLanguage -OwnerName microsoft -RepositoryName PowerShellForGitHub -Verbose
$b = Get-GitHubRepositoryLanguage -OwnerName powershell -RepositoryName powershell -Verbose

$a
>> $b

Or more simply:

$a = [PSCustomObject]@{'a' = 1} 
$b = [PSCustomObject]@{'a' = 1; 'b' = 2; 'c' = 3 }

$a
>> $b

What are you trying to accomplish with that command? It's pretty ambiguous at the moment.

@HowardWolosky, I would like to produce a list of repos and the languages used. Something like:

RepoName    Language            Loc
--------    --------            ---
repo1       PowerShell          0858
repo2       C#                  30816340
repo2       PowerShell          5130858
repo2       Roff                216538
repo2       Shell               57893
repo3       Rich Text Format    40664
repo3       HTML                18166

ConvertFrom-Json converts a json string into a [PSCustomObject], and that's what PowerShellForGitHub is built on top of (as is almost any PowerShell module that interacts with a REST Api). The objects that come out of that Get-GitHubRepositoryLanguage are not guaranteed to have the same properties however (both PowerShell and PowerShellForGitHub have a PowerShell property, but PowerShell has a number of other ones as well). PowerShell doesn't know how to merge disparate [PSCustomObject]s into a single table.

To achieve that list, you'll need to do post-processing of the data. Something like this:

$repos = @(
    @{'owner' = 'PowerShell'; 'name' = 'PowerShell' },
    @{'owner' = 'microsoft'; 'name' = 'PowerShellForGitHub' }
)

$repoLanguages = @()

foreach ($repo in $repos)
{
    $result = Get-GitHubRepositoryLanguage -OwnerName $repo.owner -RepositoryName $repo.name
    foreach ($lang in $result.PSObject.Properties.Name)
    {
        $repoLanguages += [PSCustomObject]@{
            'owner' = $repo.owner
            'repo' = $repo.name
            'language' = $lang
            'loc' = $result.$lang
        }
    }
}

# this will spit out a table that matches what you're looking for:
$repoLanguages

<#
