Functions

func AddRemote 

func AddRemote(dir, name, url string) error

AddRemote adds a named remote pointing at url.

func CherryPick 

func CherryPick(dir, rev string) error

CherryPick applies the changes from a single commit onto the current branch, creating a new commit. Can conflict (uses the same conflict machinery as merge/rebase); resolve then CherryPickContinue, or CherryPickAbort.

func CherryPickAbort 

func CherryPickAbort(dir string) error

CherryPickAbort cancels an in-progress cherry-pick and restores the pre-cherry-pick state.

func CherryPickContinue 

func CherryPickContinue(dir string) error

CherryPickContinue resumes an in-progress cherry-pick after conflicts are resolved and staged.

func Clone 

func Clone(url, dest string) (string, error)

Clone clones url into dest. dest is the target directory for the working copy (e.g. C:\repos\gitmate). If dest is empty, git derives it from the URL's repo name, placed under the current directory. Returns the absolute path of the resulting repo directory.

Unlike other operations, clone runs OUTSIDE any existing repo — git is invoked in dest's parent directory (created if needed) so the clone lands correctly.

func CommitMerge 

func CommitMerge(dir string) (string, error)

CommitMerge finishes an in-progress merge by committing with git's prepared MERGE_MSG (no editor). Use after all conflicts are resolved + staged. Returns the new commit's short hash.

func ConflictedFiles 

func ConflictedFiles(dir string) ([]string, error)

ConflictedFiles returns paths currently in a conflicted (unmerged) state.

func CreateCommit 

func CreateCommit(dir, message string) (string, error)

CreateCommit creates a commit with the given message and returns the new short hash.

func CreateTag 

func CreateTag(dir, name, message string) error

CreateTag makes a tag at HEAD. If message is non-empty it's an annotated tag (-a -m); otherwise a lightweight tag. Fails if the tag already exists.

func CurrentBranch 

func CurrentBranch(dir string) (string, error)

CurrentBranch returns the checked-out branch name.

func DeleteBranch 

func DeleteBranch(dir, name string, force bool) error

DeleteBranch deletes a branch. With force=false it uses safe delete (-d), which refuses to delete a branch holding commits not merged elsewhere. With force=true it uses -D, deleting regardless (may orphan commits). Git refuses to delete the currently checked-out branch either way.

func DeleteRemoteTag 

func DeleteRemoteTag(dir, name string) error

DeleteRemoteTag deletes a tag from origin (git push origin --delete <tag>). Local deletion is separate (DeleteTag) — this only removes it from the remote.

func DeleteTag 

func DeleteTag(dir, name string) error

DeleteTag removes a local tag.

func Discard 

func Discard(dir string, paths ...string) error

Discard throws away working-tree changes to tracked paths, restoring them to their staged/HEAD state. This is DESTRUCTIVE — uncommitted edits are lost and cannot be recovered. It does not touch untracked files (git restore ignores them); callers should guard against passing untracked paths.

func Fetch 

func Fetch(dir, remote string) error

Fetch downloads objects and refs from a remote without merging. Empty remote defaults to "origin". Updates remote-tracking branches (so ahead/behind reflect the remote) but does not touch the working tree.

func FetchTags 

func FetchTags(dir string) error

FetchTags syncs tags from origin, pruning local tags that were deleted on the remote (so ListTags reflects the remote after e.g. a browser-side deletion).

func GetRemoteURL 

func GetRemoteURL(dir, name string) (string, error)

GetRemoteURL returns the URL of the named remote (e.g. "origin").

func HeadSHA 

func HeadSHA(dir string) (string, error)

HeadSHA returns the full commit SHA that HEAD currently points at. Used to capture a restore point before a history-moving operation (merge/rebase/reset).

func IsRepo added in v0.7.0 

func IsRepo(dir string) bool

IsRepo reports whether dir is inside a git working tree. Used to gate all git and GitHub operations so the app doesn't fire (and cascade-fail) when launched in a non-repository folder.

func LastCommitSubject 

func LastCommitSubject(dir, branch string) (string, error)

LastCommitSubject returns the subject line of the most recent commit on the given branch (or HEAD if branch is empty). Used to default a PR title.

func MarkResolved 

func MarkResolved(dir, path string) error

MarkResolved stages a (hand-edited) conflicted file, marking it resolved.

func MaybeRunRebaseEditor 

func MaybeRunRebaseEditor(args []string) (handled bool, exitCode int)

MaybeRunRebaseEditor checks os.Args for the hidden rebase-editor subcommands and, if present, performs the edit and returns true (the caller should then exit). Both the CLI and GUI mains call this at the very top of main() so that when git invokes "<self> __rebase-seq-editor <prepared> <gitTodo>" the process does the copy and exits — no external script, identical on every OS.

Returns (handled, exitCode). When handled is true, main must exit with exitCode. When false, main proceeds normally.

func Merge 

func Merge(dir, branch string) error

Merge merges the named branch into the current branch. On conflicts git exits non-zero and leaves conflict markers; that error is returned to surface.

func MergeAbort 

func MergeAbort(dir string) error

MergeAbort aborts an in-progress merge, restoring the pre-merge state.

func MergeInProgress 

func MergeInProgress(dir string) bool

MergeInProgress reports whether a merge is underway (MERGE_HEAD exists).

func Pull 

func Pull(dir string, rebase bool) error

Pull integrates remote changes into the current branch. rebase=true replays local commits on top of upstream (linear); otherwise merges. Either mode can conflict — returned as an error for the caller to surface.

func Push 

func Push(dir, remote, branch string, setUpstream bool) error

Push pushes a branch to a remote. setUpstream adds -u to link the local branch to remote/<branch> (needed the first time a branch is pushed).

func PushTag 

func PushTag(dir, name string) error

PushTag pushes a single tag to origin. This is what triggers a tag-based release workflow — tags do NOT travel with a normal `git push`.

func ReadPRTemplate 

func ReadPRTemplate(dir string) string

ReadPRTemplate returns the repo's PR template contents, or "" if none.

func Rebase 

func Rebase(dir, base string) error

Rebase replays the current branch's commits on top of base. Like merge it can conflict — but per replayed commit, so it may stop repeatedly. On conflict git exits non-zero; resolve then RebaseContinue, or RebaseAbort to bail.

func RebaseAbort 

func RebaseAbort(dir string) error

RebaseAbort aborts an in-progress rebase, restoring the pre-rebase state.

func RebaseContinue 

func RebaseContinue(dir string) error

RebaseContinue resumes a rebase after conflicts are resolved and staged.

func RebaseInProgress 

func RebaseInProgress(dir string) bool

RebaseInProgress reports whether a rebase is underway (the rebase-merge or rebase-apply state dir exists under .git).

func RemoveRemote 

func RemoveRemote(dir, name string) error

RemoveRemote deletes a remote reference (does not touch commits).

func RenameBranch 

func RenameBranch(dir, oldName, newName string) error

RenameBranch renames a branch (git branch -m). Renaming the current branch is allowed.

func RenameRemote 

func RenameRemote(dir, oldName, newName string) error

RenameRemote renames a remote (and its remote-tracking refs).

func RepoRoot 

func RepoRoot(dir string) string

RepoRoot resolves dir to the top level of its git working tree (via rev-parse --show-toplevel). Returns the input unchanged if resolution fails (e.g. not a repo yet). The GUI uses this to pin repoDir to the repo ROOT, so path-relative git commands don't resolve against a subdirectory like gui/.

func Reset 

func Reset(dir, rev string, mode ResetMode) error

Reset moves HEAD to rev using the given mode.

func ResolveOurs 

func ResolveOurs(dir, path string) error

ResolveOurs resolves a file by taking our side entirely (git checkout --ours).

func ResolveTheirs 

func ResolveTheirs(dir, path string) error

ResolveTheirs resolves a file by taking their side entirely (git checkout --theirs).

func Revert 

func Revert(dir, rev string) error

Revert creates a NEW commit that undoes the changes of a previous commit — the safe, history-preserving undo (unlike Reset, which rewrites history). Can conflict; resolve then RevertContinue, or RevertAbort.

func RevertAbort 

func RevertAbort(dir string) error

RevertAbort cancels an in-progress revert and restores the pre-revert state.

func RevertContinue 

func RevertContinue(dir string) error

RevertContinue resumes an in-progress revert after conflicts are resolved and staged.

func RunInteractiveRebase 

func RunInteractiveRebase(dir, base string, steps []RebaseStep) error

RunInteractiveRebase performs an interactive rebase onto base, applying the given plan (reorder/drop/squash/fixup/reword) by driving git non-interactively via the injectable sequence/message editors.

func SequencerInProgress 

func SequencerInProgress(dir string) (cherryPick bool, revert bool)

SequencerInProgress reports whether a cherry-pick or revert is mid-operation (paused on a conflict). Both use git's "sequencer" state.

func SmartDeleteTag 

func SmartDeleteTag(dir, name string) (string, error)

SmartDeleteTag deletes a tag wherever it exists: local, remote, or both. It checks presence first so it never errors trying to delete a side that isn't there. Returns a short description of what was removed.

func Stage 

func Stage(dir string, paths ...string) error

Stage runs `git add`. With no paths, stages everything (new, modified, deleted).

func StageHunk 

func StageHunk(dir, path string, h Hunk) error

StageHunk stages a single hunk of a file by building a patch for just that hunk and applying it to the index (git apply --cached). This is how you stage part of a file's changes without staging the whole file.

func StashApply 

func StashApply(dir, ref string) error

StashApply applies a stash WITHOUT removing it from the stash list (unlike StashPop, which applies and drops). Empty ref applies the most recent.

func StashDrop 

func StashDrop(dir, ref string) error

StashDrop discards a stash entry without applying it. An empty ref drops the most recent. Destructive — the stashed changes are lost.

func StashPop 

func StashPop(dir, ref string) error

StashPop applies the stash at the given ref and removes it from the stash list. An empty ref pops the most recent (stash@{0}).

func StashSave 

func StashSave(dir, message string, includeUntracked bool) error

StashSave stashes tracked working-tree and index changes. If message is non-empty it's used as the stash description. includeUntracked also stashes untracked files (git stash push -u). Returns nil even if there was nothing to stash — callers can re-check status.

func Switch 

func Switch(dir, branch string) error

Switch changes the checked-out branch. Git refuses if uncommitted changes would be overwritten; that refusal is returned as an error for the caller to surface (commit, discard, or — once available — stash first).

func SwitchNew 

func SwitchNew(dir, branch string) error

SwitchNew creates a new branch from the current HEAD and switches to it (git switch -c). Fails if the branch already exists.

func UndoTo 

func UndoTo(dir, sha string) error

UndoTo hard-resets HEAD back to a previously captured SHA — the mechanism behind "undo last operation". The pre-undo state remains recoverable via the reflog, so an undo is itself reversible.

func Unstage 

func Unstage(dir string, paths ...string) error

Unstage removes paths from the index (staged -> unstaged), leaving the working tree untouched. With no paths, unstages everything.

func UnstageHunk 

func UnstageHunk(dir, path string, h Hunk) error

UnstageHunk removes a single staged hunk from the index by applying its patch in reverse against the index (git apply --cached --reverse).

	Subject string       // commit subject (for display)
	Action  RebaseAction // pick/reword/squash/fixup/drop
	Message string       // replacement/combined message for reword & squash; empty otherwise
}

RebaseStep is one line of the interactive-rebase plan: a commit + the action to take, plus (for reword/squash) an optional replacement message.

func InteractiveRebaseTodo 

func InteractiveRebaseTodo(dir, base string) ([]RebaseStep, error)

func Reflog 

func Reflog(dir string, limit int) ([]ReflogEntry, error)

Reflog returns HEAD's reflog, newest first, up to limit entries (0 = all). This is the "undo safety net" — every position HEAD has held, so a bad reset or rebase can be traced back and recovered.

}

Remote is a named remote and its fetch URL.

func ListRemotes 

func ListRemotes(dir string) ([]Remote, error)

type ResetMode string

ResetMode is soft (move HEAD, keep index + working tree), mixed (move HEAD + reset index, keep working tree — the default), or hard (move HEAD + reset index + working tree, DISCARDING uncommitted changes and orphaning commits after the target — recoverable via reflog until it expires). 

const (
	ResetSoft  ResetMode = "soft"
	ResetMixed ResetMode = "mixed"
	ResetHard  ResetMode = "hard"
)
