# Mercurial support for Smalltalk/X

**stx:libscm** is a new source code management library for [Smalltalk/X][1]. Currently only [Mercurial][2] is supported

but its design allow for other source code management systems to by plugged in if required.

The Mercurial support consist of:

* low-level Mercurial API allowing to query and manipulate Mercurial repositories

* Integration into Smalltalk/X IDE allowing to commit, branch or merge Smalltalk/X packages directly within Smalltalk/x IDE. 

## Installation

1.  **Install Mercurial command line client.** 

    See [Mercurial wiki page](http://mercurial.selenic.com/wiki/Download) for details 

    how to install Mercurial on your machine. 

2.  **Download and run an installer script**

    Download [`HGInstaller.st`](https://bitbucket.org/janvrany/stx-libscm/raw/default/mercurial/HGInstaller.st) script and run it as:

    `stx --execute HGInstaller.st`

**NOTE**: Smalltalk/X *jv-branch* has Mercurial support already included,

so there's no need to install it explicitly.

See [installation instruction](https://bitbucket.org/janvrany/stx-libscm/wiki/Installation) for more details.

## Supported version

**stx:libscm** works - to some extent - on three Smalltalk/X versions

- [Smalltalk/X "jv branch"][6] - fully "supported" (i.e, all features should work, this is where libscm development takes place)

- Smalltalk/X "eXept HEAD" - should work, though not regularly tested. If not, please file in a bugreport here. 

- [Smalltalk/X 6.2.2][1] - generally not supported. The last version working on 6.2.2 was released as [1.0][7], which allows basic commit. If you need more recent version running on 6.2.2 (or any other older version), please contact the autor. 

For more detauls see [release notes](https://bitbucket.org/janvrany/stx-libscm/wiki/ReleaseNotes.md).
