When committing changes, by default Git only commits changes that have been staged. Use this function on each file you want to commit before committing. No other files will be committed. Use the `PassThru` switch to get `IO.FileInfo` and `IO.DirectoryInfo` objects back for each file and directory added, respectively. If the items are already added or were unmodified and not added to the staging area, you'll still get objects back for them. This function implements the `git add` command. .LINK Save-GitCommit .EXAMPLE Add-GitItem -Path 'C:\Projects\PowerGit' Demonstrates how to add all the items under a directory to the next commit to the repository in the current directory. .EXAMPLE Add-GitItem -Path 'C:\Projects\PowerGit\Functions\Add-GitItem.ps1','C:\Projects\PowerGit\Tests\Add-GitItem.Tests.ps1' Demonstrates how to add multiple items and files to the next commit. .EXAMPLE Get-ChildItem '.\PowerGit\Functions','.\Tests' | Add-GitItem Demonstrates that you can pipe paths or file system objects to Add-GitItem. When passing directories, all untracked/new or modified files under that directory are added. When passing files, only that file is added. .EXAMPLE Add-GitItem -Path 'C:\Projects\PowerGit' -RepoRoot 'C:\Projects\PowerGit' Demonstrates how to operate on a repository that isn't the current directory. .EXAMPLE Get-ChildItem | Add-GitItem Demonstrates that you can pipe `IO.FileInfo` and `IO.DirectoryInfo` objects to `Add-GitItem`. Plain strings are also allowed. .EXAMPLE Add-GitItem -Path 'file1','directory1' -PassThru Demonstrates how to get `IO.FileInfo` and `IO.DirectoryInfo` objects returned for each file and directory, respectively. #> [CmdletBinding()] param( [Parameter(Mandatory, Position = 0, ValueFromPipeline, ValueFromPipelineByPropertyName)] [Alias('FullName')] [string[]] # The paths to the files/directories to add to the next commit. $Path, [string] # The path to the repository where the files should be added.
