It gets information about each uncommitted change in your repository. Ignored items are not returned unless you provide the `IncludeIgnored` switch. You can get status for specific files and directories with the Path parameter. If you provide a `RepoRoot` parameter to work with a specific repository, the values of the `Path` parameter should be relative to the root of that repository. With no `RepoRoot` parameter, the paths in the `Path` parameter are treated as relative to the current directory. Wildcards are supported and are passed directly to Git to evaluate (i.e. use Git wildcard syntax not PowerShell's). The `LibGit2Sharp.StatusEntry` objects returned have several extended type data members added. You should use these members instead of using the object's `State` property. * `IsStaged`: `$true` if the item has been staged for the next commit; `$false` otherwise. * `IsAdded`: returns `$true` if the item is new in the working directory or has been staged for the next commit; `$false` otherwise. * `IsConflicted`: returns `$true` if the item was merged and currently has conflicts; `$false` otherwise. * `IsDeleted`: returns `$true` if the item was deleted from the working directory or has been staged for removal in the next commit; `$false` otherwise. * `IsIgnored`: returns `$true` if the item is ignored; `$false` otherwise. You'll only see ignored items if you use the `IncludeIgnored` switch. * `IsModified`: returns `$true` if the item is modified; `$false` otherwise. * `IsRenamed`: returns `$true` if the item was renamed; `$false` otherwise. * `IsTypeChanged`: returns `$true` if the item's type was changed; `$false` otherwise. * `IsUnchanged`: returns `$true` if the item is unchanged; `$false` otherwise. * `IsUnreadable`: returns `$true` if the item is unreadable; `$false` otherwise. * `IsUntracked`: returns `$true` if the item is untracked (i.e. hasn't been staged or added to the repository); `$false` otherwise. When displayed in a table (the default), the first column will show characters that indicate the state of each item, e.g. State FilePath ----- -------- a PowerGit\Formats\LibGit2Sharp.StatusEntry.ps1xml a PowerGit\Functions\Get-GitRepositoryStatus.ps1 m PowerGit\PowerGit.psd1 a PowerGit\Types\LibGit2Sharp.StatusEntry.types.ps1xml a Tests\Get-GitRepositoryStatus.Tests.ps1 The state will display: * `i` if the item is ignored (i.e. `IsIgnored` returns `$true`) * `a` if the item is untracked or staged for the next commit (i.e. `IsAdded` returns `$true`) * `m` if the item was modified (i.e. `IsModified` returns `$true`) * `d` if the item was deleted (i.e. `IsDeleted` returns `$true`) * `r` if the item was renamed (i.e. `IsRenamed` returns `$true`) * `t` if the item's type was changed (i.e. `IsTypeChanged` returns `$true`) * `?` if the item can't be read (i.e. `IsUnreadable` returns `$true`) * `!` if the item was merged with conflicts (i.e. `IsConflicted` return `$true`) If no state characters are shown, the file is unchanged (i.e. `IsUnchanged` return `$true`). This function implements the `git status` command. .EXAMPLE Get-GitRepositoryStatus Demonstrates how to get the status of any uncommitted changes for the repository in the current directory. .EXAMPLE Get-GitRepositoryStatus -RepoRoot 'C:\Projects\PowerGit' Demonstrates how to get the status of any uncommitted changes for the repository at a specific location. .EXAMPLE Get-GitRepositoryStatus -Path 'build.ps1','*.cs' Demonstrates how to get the status for specific files at or under the current directory using the Path parameter. In this case, only modified files named `build.ps1` or that match the wildcard `*.cs` under the current directory will be returned. .EXAMPLE Get-GitRepositoryStatus -Path 'build.ps1','*.cs' -RepoRoot 'C:\Projects\PowerGit` Demonstrates how to get the status for specific files under the root of a specific repository. In this case, only modified files named `build.ps1` or that match the wildcard `*.cs` under `C:\Projects\PowerGit` will be returned. #> [CmdletBinding()] [OutputType([LibGit2Sharp.StatusEntry])] param( [Parameter(Position = 0)] [string[]] # The path to specific files and/or directories whose status to get.
