README

vcs

Package vcs provides a more complete version control system (ex: git) interface, building on Masterminds/vcs.

It adds the following methods on top of what is available in Masterminds/vcs:

  • Files: files in the repository, and their FileStatus

  • Add, Move, Delete, CommitFile, RevertFile: manipulate files in the repository.

  • Log, CommitDesc, Blame: details on prior commits

The total interface is now sufficient for complete management of a VCS.

Current Status

Only git and svn are currently supported in vcs; other repositories supported in vcs include Mercurial (Hg) and Bazaar (Bzr); contributions from users of those VCS's are welcome.

Functions

func AllFiles 

func AllFiles(path string) ([]string, error)

AllFiles returns a slice of all the files, recursively, within a given directory

func DetectRepo 

func DetectRepo(path string) vcs.Type

DetectRepo attempts to detect the presence of a repository at the given directory path -- returns type of repository if found, else vcs.NoVCS. Very quickly just looks for signature file name: .git for git .svn for svn -- but note that this will find any subdir in svn repo

func FieldsThroughDelim 

func FieldsThroughDelim(flds [][]byte, delim byte, idx int) (int, string)

FieldsThroughDelim gets the concatenated byte through to point where field ends with given delimiter, starting at given index

func RelPath 

func RelPath(repo Repo, path string) string

RelPath return the path relative to the repository LocalPath()

Types

type Commit 

type Commit struct {

	// revision number / hash code / unique id
	Rev string

	// date (author's time) when committed
	Date string

	// author's name
	Author string

	// author's email
	Email string

	// message / subject line for commit
	Message string `width:"100"`
}

Commit is one VCS commit entry, as returned in a Log

type FileStatus 

type FileStatus int32 //enums:enum

FileStatus indicates the status of files in the repository 

const (
	// Untracked means file is not under VCS control
	Untracked FileStatus = iota

	// Stored means file is stored under VCS control, and has not been modified in working copy
	Stored

	// Modified means file is under VCS control, and has been modified in working copy
	Modified

	// Added means file has just been added to VCS but is not yet committed
	Added

	// Deleted means file has been deleted from VCS
	Deleted

	// Conflicted means file is in conflict -- has not been merged
	Conflicted

	// Updated means file has been updated in the remote but not locally
	Updated
