What is Hg4J
Hg4J is an independent pure Java implementation of a popular Mercurial distributed version control system.
From a developer's perspective, Hg4J is a software library that provides an API enabling Java applications to read and modify local and remote Mercurial repositories.
Hg4J Major Features
Inititally we focused on read-only functionality, and Hg4J version 1.0 might be sufficient if your application doesn't need to alter repository in any way. History ('hg log'), status ('hg status') and get content ('hg cat') are most common operations for regular use. Besides, 1.0 knows how to detect incoming and outgoing changes, and provides access to various Mercurial control files - pretty much that's it what you can do without touching a repository
Latest release, Hg4J version 1.1, is not that shy about repository changes any longer. We've decided to touch local repositories and working directories first:
- Manage working directory: checkout, revert, add/remove files
- Deliver changes: commit command
- Respect others: working directory and storage area locks
- Blame: annotate and diff commands
- Understand phases and bookmarks
- Read-only support for mq and rebase extensions
If you're curious what's next, Hg4J version 1.2 is on the way, sheduled for release later this year, with focus on operations with remote servers. Looking forward to SSH repositories, push and pull commands and a lot of other improvements
Hg4J runs with Java™ 5 with no external dependency whatsoever
