ironflow-ops-git 0.1.0

//! Git operations for Ironflow workflows, powered by [`git2`].
//!
//! This crate provides a comprehensive set of Git operations as Ironflow
//! [`Operation`](ironflow_core::operation::Operation) implementations. Each
//! operation wraps a [`git2`] API call, running it inside
//! [`spawn_blocking`](tokio::task::spawn_blocking) since `git2` is synchronous.
//!
//! # Architecture
//!
//! - [`GitRepo`] is the central handle, wrapping a repository path
//! - Each operation is a standalone struct implementing [`Operation`](ironflow_core::operation::Operation)
//! - All operations return `kind() == "git"`
//! - Parameters are set at construction time, not via [`OperationContext`](ironflow_core::operation::OperationContext)
//!
//! # Quick start
//!
//! ```no_run
//! use ironflow_ops_git::GitRepo;
//! use ironflow_ops_git::repository::RepoInit;
//! use ironflow_ops_git::commit::CommitCreate;
//! use ironflow_ops_git::index::IndexAdd;
//! use ironflow_core::operation::{Operation, OperationContext, NoopSecretResolver};
//! use std::sync::Arc;
//!
//! # async fn example() -> Result<(), ironflow_core::error::OperationError> {
//! let ctx = OperationContext::new(Arc::new(NoopSecretResolver));
//!
//! // Initialize a repo
//! let init = RepoInit::new("/tmp/my-repo", false);
//! init.execute(&ctx).await?;
//!
//! // Stage a file and commit
//! let add = IndexAdd::new("/tmp/my-repo", "README.md");
//! add.execute(&ctx).await?;
//!
//! let commit = CommitCreate::new("/tmp/my-repo", "Initial commit", "Alice", "alice@example.com");
//! commit.execute(&ctx).await?;
//! # Ok(())
//! # }
//! ```
//!
//! # Tracked operations
//!
//! Every operation implements [`Operation`](ironflow_core::operation::Operation),
//! so it can be passed to `WorkflowContext::operation()` for step lifecycle
//! tracking (step record, status transitions, duration, output persistence).
//!
//! # Modules
//!
//! Operations are organized by Git domain:
//!
//! | Module | Operations |
//! |--------|-----------|
//! | [`repository`] | Init, Open, Clone, Discover, State |
//! | [`index`] | Add, AddAll, Remove, RemoveAll, UpdateAll, WriteTree |
//! | [`commit`] | Create, Find, Amend, Signed |
//! | [`branch`] | Create, Delete, Rename, List, Lookup, IsHead, SetUpstream |
//! | [`tag`] | CreateLightweight, CreateAnnotated, Delete, List, ListMatch |
//! | [`remote`] | Create, Delete, Rename, SetUrl, List, Lookup |
//! | [`fetch`] | Fetch, Push, Prune, DefaultBranch |
//! | [`merge`] | Branch, Analysis, Commits, Base, CleanupState |
//! | [`rebase`] | Init, Next, Commit, Abort, Finish |
//! | [`cherrypick`] | Cherrypick, CherrypickCommit, Revert, RevertCommit |
//! | [`stash`] | Save, Apply, Pop, Drop, List |
//! | [`diff`] | TreeToTree, TreeToIndex, IndexToWorkdir, Stats, FindSimilar, Apply |
//! | [`checkout`] | Head, Index, Tree |
//! | [`blame`] | BlameFile |
//! | [`log`] | RevwalkNew, RevwalkPushRange, RevwalkSimplifyFirstParent |
//! | [`refs`] | Create, Delete, Rename, Lookup, NameToId |
//! | [`reflog`] | Read, Append, Drop |
//! | [`submodule`] | Add, Init, Update, Lookup, List |
//! | [`worktree`] | Add, List, Validate, Prune |
//! | [`config`] | Get, Set, Delete, List |
//! | [`status`] | File, List, ShouldIgnore |
//! | [`reset`] | Reset (soft, mixed, hard) |
