Hackable Mercurial for Windows
An approach to easily hack on the Mercurial source on Windows.
Contents
1. What is the Hackable package?
Compiling Mercurial is a significant barrier to testing and developing Mercurial on Windows. This package attempts to minimize that barrier by including:
- a private copy of Python (32-bit)
- complete Mercurial history
- pre-compiled extensions (32-bit MinGW GCC)
- an hg.exe wrapper to add to your path
- in-place editable source checked out and ready to go
2. Downloading and using
The package can be found here. Simply download, unzip, and run the included hg.exe. Simply use hg pull and hg update to upgrade to the latest version.
This package will not interfere with your existing Mercurial or Python installation.

This package includes no global configuration, so if you're not already using Mercurial, you will need to configure your username and merge tools.
3. How it's built and how to build your own from scratch
Needed components:
- Python MSI installer, versions 2.4 - 2.7
- Mercurial source release, see [Downloads]
MinGW mingw-get tool
The exemaker launcher
Steps:
- Download all the needed components
Install Python with msiexec /i python-2.6.6.msi /qb
Unpack the mingw-get tool into c:\MinGW and add c:\MinGW\bin to your path
Install the gcc compiler with mingw-get gcc
Unpack Mercurial source into c:\hg
Copy the Python install from c:\Python26 to c:\hg\hg-python26
Edit c:\hg\hg-python26\Lib\distutils\cygwinccompiler.py to remove all references to -mno-cygwin (thanks, GCC!)
Build Mercurial extensions in c:\hg with hg-python26\python setup.py build_ext -i --compiler=mingw32
Copy the c:\hg\hg to c:\hg.py and change the #! line to '#!hg-python/python.exe'
Unpack exemaker and copy exemaker.exe to c:\hg\hg.exe
