<# .SYNOPSIS git log input .DESCRIPTION Extends the parameters for git log, making it easier to use from PowerShell. Allows timeframe parameters to be tab-completed: * After/Since become --after * Before/Until become --before * Author/Committer become --author Adds -CurrentBranch, which gives the changes between the upstream branch and the current branch. Also adds -IssueNumber, which searchers for commits that reference particular issues. .EXAMPLE git log -CurrentBranch #> [ValidatePattern('^git log')] [Management.Automation.Cmdlet("Use","Git")] [CmdletBinding(PositionalBinding=$false)] param( # The number of entries to get. [Alias('CommitNumber','N','Number')] [int] $NumberOfCommits, # Gets logs after a given date [DateTime] [Alias('Since')] $After, # Gets before a given date [DateTime] [Alias('Until')] $Before, # Gets lof from a given author or committer [Alias('Committer')] [string] $Author, # If set, will get all changes between the upstream branch and the current branch. [Alias('UpstreamDelta','ThisBranch')] [switch] $CurrentBranch, # One or more issue numbers. Providing an issue number of 0 will find all log entries that reference an issue. [Parameter(ValueFromPipelineByPropertyName)] [Alias('ReferenceNumbers','ReferenceNumber','IssueNumbers','WorkItemID','WorkItemIDs')] [int[]] $IssueNumber, # If set, will get statistics associated with each change [Alias('Stat')] [switch] $Statistics, # If provided, will search for specific strings within the change sets of a commit. # This is especially useful when finding references to or changes to a given function or structure. [Parameter(ValueFromPipelineByPropertyName)] [Alias('Search')] [string] $SearchString, # If provided, will search for specific patterns within the change sets of a commit. # This is especially useful when finding references to or changes to a given function or structure. [Parameter(ValueFromPipelineByPropertyName)] [Alias('Pattern')] [string] $SearchPattern ) # If the number of commits was provided, it should come first. if ($NumberOfCommits) { '-n' "$NumberOfCommits" } foreach ($dashToDoubleDash in 'after', 'before', 'author') { if ($PSBoundParameters[$dashToDoubleDash]) { "--$dashToDoubleDash" "$($PSBoundParameters[$dashToDoubleDash])" } } if ($CurrentBranch) { $headbranch = git remote | git remote show | Select-Object -ExpandProperty HeadBranch -First 1 $currentBranchName = git branch | Where-Object IsCurrentBranch if ($currentBranchName -ne $headbranch) { "$headbranch..$currentBranchName" } else { Write-Warning "On $headBranch" } } if ($IssueNumber) { "--perl-regexp" foreach ($IssueNum in $IssueNumber) { '--grep' if ($IssueNum -eq 0) { '\#\d+\D' } else { "\#$IssueNum\D" } } } if ($SearchString) { "-S" $SearchString } if ($SearchPattern) { "-G" $SearchPattern } if ($Statistics) { '--stat' } |
