LONG DESCRIPTION

Powershell Driven Git

Powdrgit is a PowerShell module that makes it easy to work across repositories and branches.

Rather than providing wrappers around existing git functionality, the module is centered around functions that handle repositories and branches as PowerShell objects, and can therefore leverage the PowerShell pipeline for gathering information or making changes to many repositories or branches at once. The module also includes functions that allow object handling for commits and tags, and other functions related to git and Powdrgit configuration.

The module functions

For working across repositories and branches:

• Get-GitRepo
• Set-GitRepo
• Get-GitBranch
• Set-GitBranch

For working inside a repository:

• Get-GitCommit
• Get-GitCommitFile
• Get-GitFileHistory
• Get-GitLog
• Get-GitTag
• Invoke-GitExpression
• Get-GitDiff
• Format-GitDiff

For repository management and Powdrgit configuration:

• New-GitRepo
• Invoke-GitClone
• Find-GitRepo
• Remove-GitRepo
• Get-GitConfigFile
• Add-PowdrgitPath
• Remove-PowdrgitPath
• Test-PowdrgitPath

---

QUICK START GUIDE

1. Install the module.

The module is available through the PowerShell Gallery. Run the following command in a PowerShell console to install the module:

Install-Module -Name powdrgit -Force

Run the following to import the module into the current session:

Import-Module -Name powdrgit

To see the list of available commands:

Get-Command -Module powdrgit

If you see a list of functions similar to those above, your install was successful.

To see a list of aliases:

Get-Alias | Where-Object ModuleName -eq powdrgit | Select-Object Name,ResolvedCommand

2. Configure Powdrgit.

Powdrgit needs to know which repositories you're interested in working with. It does this by storing a list of paths to those repositories in a module variable $Powdrgit.Path. Powdrgit will only 'see' repos that are in that list. There are a number of ways to populate the list:

• Plain ol' variable assignment:
  • Once the module is loaded, simply add the paths you want, e.g.:

    $Powdrgit.Path = 'C:\PowdrgitExamples\MyToolbox;C:\PowdrgitExamples\Project1'
    

  • $Powdrgit.Path can also be updated using any standard Powershell technique.
• Use the Find-GitRepo function:
  • Find-GitRepo can help you find git repositories on your computer. Using the -SetPowdrgitPath switch will replace the existing list with a list of all of the repository paths it just found. Using the -AppendPowdrgitPath switch will add any of the paths it just found to the list (if they're not already there). E.g.:

    Find-GitRepo -Path 'C:\' -SetPowdrgitPath
    

    This will set $Powdrgit.Path to the list of all repositories on your C drive.
• Use the Add-PowdrgitPath and Remove-PowdrgitPath functions:
  • Paths can be added and removed using Add-PowdrgitPath and Remove-PowdrgitPath. Also, some module functions have switches that will update $Powdrgit.Path for you. E.g.:

    Add-PowdrgitPath -Path 'C:\PowdrgitExamples\MyToolbox;C:\PowdrgitExamples\Project1'
    

To have the configuration available whenever a console window is opened, put the commands into your PowerShell profile.

3. Check the configuration.

Run:

Test-PowdrgitPath

If a path that was added is not actually git repository (i.e. doesn't have a .git subdirectory or is not a bare .git directory), or doesn't exist, a warning is generated. It's safe to leave them in the list, however, as Powdrgit will just ignore them. Whether or not any warnings were generated, Test-PowdrgitPath will also output a number, which shows the number of valid paths in the list.

4. Run your first command.

You're good to go! Simply run:

Get-GitRepo

You should see the valid repositories that you just added to $Powdrgit.Path. The Powdrgit module always takes the name of the top-level repository directory as the repository name. It does not use values from a repository's config or origin URL as the name.

---

---

LEARNING THE COMMANDS

Each function has numerous examples to help you understand how the function can be used and what results it provides. To view the help for any function, use PowerShell's built-in Get-Help function, e.g.:

Get-Help -Full Get-GitRepo

Many of the examples refer to repositories in the C:\PowdrgitExamples directory. If you'd like to follow along with the examples verbatim, you can use the following script to create the example repositories:

Powdrgit Help Examples - Setup Script

The script is also available in the module folder at powdrgit\scripts\PowdrgitHelpExampleSetup.ps1.

Note: the SHA1Hash values in the examples will be different to the ones you see on your own computer.

FURTHER CONFIGURATION

Powdrgit has a module variable, $Powdrgit, that has various properties that can customize the behavior of Powdrgit:

• .AutoCompleteFullPaths:
  • When set to $true, autocompletion values for any -Repo parameter will always show the full path of the repository. When set to $false, if the repository name is unique within Powdrgit, then only the name of the repository is shown. If a repository name is not unique within Powdrgit, the full path is always shown.
  • Default is $false.
• .BranchExcludes:
  • PowerShell object array that contains filters used to limit the branches displayed with Get-Gitbranch.
  • Default is an empty object: [PSCustomObject]@{ RepoPattern = ''; BranchPattern = ''; ApplyTo = '' }.
• .BranchExcludesNoWarn:
  • Suppresses the warning message shown by Get-GitBranch when branches have been excluded by a filter.
  • Default is $false.
• .DebugIndentChar:
  • Debug output is indented to match the nested depth of the function. The first character of $Powdrgit.DebugIndentChar is used as the first character of the indent.
  • Default is >.
• .DefaultCloneUrl:
  • When frequently cloning repositories from the same collection, the only part of the URL that may change is the name of the repository. $Powdrgit.DefaultCloneUrl can hold the URL, with a placeholder, <RepoName>, for the repository name. Then, when using Invoke-GitClone, only the repository name needs to be provided. A full URL can always be used regardless of the value of $Powdrgit.DefaultCloneUrl.
  • Default is $null.
• .DefaultDir:
  • When working with many repositories, if they are kept in the same parent directory, it can be useful to set $Powdrgit.DefaultDir to this directory. This then allows using the UseDefaultDir switch instead of having to explicitly specify the path.
  • Default is $null.
• .DefaultGitScriptSeparator:
  • Contains the default script separator for commands passed to the -GitScript parameter of Set-GitBranch. If required, the -GitScriptSeparator parameter can be used to override this default at the time the command is run.
  • Default is ;.
• .DefaultInitialCommit:
  • When creating new repositories, it may be desirable to make an initial commit to the repository before any further changes are made. New-GitRepo allows the message for the initial commit to be specified. If the same message is always required for the initial commit, the message can be specified in $Powdrgit.DefaultInitialCommit and applied using the -UseDefaultInitialCommit switch.
  • Default is 'Initial commit'.
• .DiffLineColorNew:
  • Color to use for displaying new (added) lines in a diff with Format-GitDiff.
  • Default is 'Cyan'.
• .DiffLineColorOld:
  • Color to use for displaying old (removed) lines in a diff with Format-GitDiff.
  • Default is 'Magenta'.
• .DiffLineColorSame:
  • Color to use for displaying unchanged lines in a diff with Format-GitDiff.
  • Default is 'DarkGray'.
• .DiffLineColorSame:
  • Color to use for displaying file summary information in a diff with Format-GitDiff.
  • Default is 'Gray'.
• .Path:
  • As described earlier, $Powdrgit.Path holds a semicolon separated list of repository paths. A repository's path needs to be in $Powdrgit.Path for the repository to be visible in Powdrgit.
  • Default is $null.
• .ShowWarnings:
  • Controls whether Powdrgit generates warnings.
  • Default is $true.
