PowerShellForGitHub PowerShell Module

Usage

Table of Contents

Full Module Documentation

All commands for the module have "Comment-Based Help" available at your fingertips. You can access that help at any time by running:

Get-Help -Full <commandName>

In addition to accessing it from the commandline, all of that help documentation is also available online on our wiki.

Logging

All commands will log to the console, as well as to a log file, by default. The logging is affected by configuration properties (which can be checked with Get-GitHubConfiguration and changed with Set-GitHubConfiguration).

LogPath [string] The logfile. Defaults to ([System.Environment]::GetFolderPath('MyDocuments'))\PowerShellForGitHub.log. Will default to ([System.Environment]::GetFolderPath('LocalApplicationData'))\PowerShellForGitHub.log when there is no user profile (like in an Azure environment).

DisableLogging [bool] Defaults to $false.

LogTimeAsUtc [bool] Defaults to $false. If $false, times are logged in local time. When $true, times are logged using UTC (and those timestamps will end with a Z per the W3C standard)

LogProcessId [bool] Defaults to $false. If $true, the Process ID ($global:PID) of the current PowerShell process will be added to every log entry. This can be helpful if you have situations where multiple instances of this module run concurrently and you want to more easily isolate the log entries for one process. An alternative solution would be to use Set-GitHubConfiguration -LogPath <path> -SessionOnly to specify a different log file for each PowerShell process. An easy way to view the filtered entries for a session is (replacing PID with the PID that you are interested in):

Get-Content -Path <logPath> -Encoding UTF8 | Where { $_ -like '*[[]PID[]]*' }

Telemetry

In order to track usage, gauge performance and identify areas for improvement, telemetry is employed during execution of commands within this module (via Application Insights). For more information, refer to the Privacy Policy.

We recommend that you always leave the telemetry feature enabled, but a situation may arise where it must be disabled for some reason. In this scenario, you can disable telemetry by calling:

Set-GitHubConfiguration -DisableTelemetry -SessionOnly

The effect of that value will last for the duration of your session (until you close your console window). To make that change permanent, remove -SessionOnly from that call.

The following type of information is collected:

  • Every major command executed (to gauge usefulness of the various commands)
  • Types of parameters used with the command
  • Error codes / information

The following information is also collected, but the reported information is only reported in the form of an SHA512 Hash (to protect PII (personal identifiable information)):

  • Username
  • OwnerName
  • RepositoryName
  • OrganizationName

The hashing of the above items can be disabled (meaning that the plaint-text data will be reported instead of the hash of the data) by setting

Set-GitHubConfiguration -DisablePiiProtection -SessionOnly

Similar to DisableTelemetry, the effect of this value will only last for the duration of your session (until you close your console window), unless you call it without -SessionOnly.

The first time telemetry is tracked in a new PowerShell session, a reminder message will be displayed to the user. To suppress this reminder in the future, call:

Set-GitHubConfiguration -SuppressTelemetryReminder

Finally, the Application Insights Key that the telemetry is reported to is exposed as

Get-GitHubConfiguration -Name ApplicationInsightsKey

It is requested that you do not change this value, otherwise the telemetry will not be reported to us for analysis. We expose it here for complete transparency.

Common PowerShell API Patterns

This module adopts many of the standard PowerShell API design patterns. We want to call attention to those patterns here so that you can identify how you can most efficiently use the module.

Confirmation Required for Major Actions

All commands that result in removing/deleting an object, as well as some commands that rename objects (like renaming a repository) require user confirmation before the comamnd will be processed. You can avoid that user confirmation by passing in either -Confirm:$false or -Force.

WhatIf Supported for All State Changing Commands

Any command that isn't Get-GitHub* supports the -WhatIf switch. You can safely call that command by passing in the -WhatIf switch and know that the request will not actually be sent to GitHub. This can be useful when paired with the -Verbose switch if you are examining what is happening behind the scenes.

State Changing Commands are Silent by Default

By default, state changing commands like Set-*, Rename-*, etc... will not produce any output unless you specify the -PassThru switch. You can change that default behavior by calling

Set-GitHubConfiguration -DefaultPassThru:$true

Examples

Overview

Embracing the Pipeline

One of the major benefits of PowerShell is its pipeline -- allowing you to "pipe" a saved value or the output of a previous command directly into the next command. There is absolutely no requirement to make use of it in order to use the module, but you will find that the module becomes increasingly easier to use and more powerful if you do.

Some of the examples that you find below will show how you might be able to use it to your advantage.

Pipeline Example

Most commands require you to pass in either a Uri for the repository or its elements (the OwnerName and RepositoryName). If you keep around the repo that you're interacting with in a local var (like $repo), then you can pipe that into any command to avoid having to specify that information. Further, piping in a more specific object (like an Issue) allows you to avoid even specifying the relevant Issue number.

Without the pipeline, an interaction log might look like this:

# Find all of the issues that have the label "repro steps needed" and add a new comment to those
# issues asking for an update.
$issues = @(Get-GitHubIssue -OwnerName microsoft -RepositoryName PowerShellForGitHub -Label 'repro steps needed')
foreach ($issue in $issues)
{
    $params = @{
        'OwnerName' = 'microsoft'
        'RepositoryName' = 'PowerShellForGitHub'
        'Issue' = $issue.number
        'Body' = 'Any update on those repro steps?'
    }

    New-GitHubIssueComment @params
}

With the pipeline, a similar interaction log might look like this:

# Find all of the issues that have the label "repro steps needed" and add a new comment to those
# issues asking for an update.
Get-GitHubRepository -OwnerName microsoft -RepositoryName PowerShellForGitHub |
    Get-GitHubIssue -Label 'repro steps needed' |
    New-GitHubIssueComment -Body 'Any update on those repro steps?'

We encourage you to explore how embracing the pipeline may simplify your code and interaction with GitHub using this module!
